Description

本発明は、離型剤を金型のキャビティに良好に塗布することができる離型剤塗布装置およびこれを用いた離型剤塗布方法に関する。   The present invention relates to a release agent coating apparatus that can satisfactorily apply a release agent to a cavity of a mold, and a release agent application method using the same.

金型を用いて成形品を成形する金型成形では、成形品が金型内面に固着し取り出せないなどのトラブルを避けるために、キャビティ内面に離型剤を塗布するようになっている。離型剤の種類は、成形方法や成形品の素材によって異なるが、油、ワックス、シリコンを乳化したものが用いられることが多い。   In mold molding in which a molded product is molded using a mold, a release agent is applied to the inner surface of the cavity in order to avoid troubles such as the molded product sticking to the inner surface of the mold and cannot be taken out. The type of release agent varies depending on the molding method and the material of the molded product, but an oil, wax, and silicon emulsified are often used.

特に、精密金型に溶融合金を高温圧入し、高精度で鋳肌性状の良い成形品を短時間で大量生産するダイキャスト法において、成形品であるダイキャスト製品を高精度で鋳肌性状の良いまま取り外すために、離型剤は重要となっている。ダイキャスト製品は、自動車や家電製品等、種々の工業製品に使用されており、その中でもアルミニウム合金のダイキャスト製品は生産量が多い。   In particular, in the die casting method, in which a molten alloy is hot-pressed into a precision mold and mass-produced in a short time for high-precision molded products with good cast surface properties, the molded die-cast products have high-precision cast surface properties. The release agent is important for removing it in good condition. Die-cast products are used in various industrial products such as automobiles and home appliances. Among them, aluminum alloy die-cast products are produced in large quantities.

金型への離型剤の塗布がうまくいっていない場合には、ダイキャスト製品の外観的欠陥として、変形・湯巡り不良・湯皺・湯流れ模様・湯境・焼き付き・かじりなどが発生したり、内部欠陥として、巣が発生したりする。   If the mold release agent is not applied to the mold properly, the appearance defects of the die-cast product may include deformation, poor hot water circulation, hot water, hot water flow pattern, hot water boundary, seizure, galling, etc. The nest is generated as an internal defect.

変形とは、ダイキャスト製品が規定の形状となっていないことであり、応力集中のための収縮不均衡や押し出しピンの強度不足、冷却不均衡によって生じる。冷却不均衡は、通常、離型剤の種類、塗布量、塗布方法で解決が図られる。   Deformation means that the die-cast product does not have a prescribed shape, and is caused by shrinkage imbalance due to stress concentration, insufficient strength of the extrusion pin, and cooling imbalance. The cooling imbalance is usually solved by the type of release agent, the coating amount, and the coating method.

湯巡り不良とは、溶湯がダイキャスト製品の隅々まで充填されず、結果途中で凝固した状態をさす。薄肉部分で充填時間が短く、キャビティ内の離型剤分解によるガスがキャビティ内に残存しやすいときにおこりやすい。ガス抜きの工夫を盛り込んだ金型設計と離型剤の性状をガス発生の少ない構成に変更したり、離型剤の塗布量を減らす、高保温性の離型剤に変更するなどの対応がある。   Poor hot water circulation refers to a state in which the molten metal is not filled to every corner of the die-cast product and solidifies in the middle of the result. This is likely to occur when the filling time is short at the thin-walled portion and the gas due to decomposition of the release agent in the cavity tends to remain in the cavity. Responding to changes in mold design and degassing agent properties that incorporate degassing techniques to a configuration that generates less gas, reducing the amount of release agent applied, and changing to a highly heat-retaining release agent is there.

湯皺とは、ダイキャスト製品表面にできた不規則な皺状の模様をいい、湯流れ模様はスジ状の光沢のことである。これらの現象は金型温度が低いときや離型剤から発生したガスが高圧になり、ダイキャスト製品の表面を押したり、離型剤の塗布量が多い場合に発生する。対策としては、付着性のよい離型剤を低濃度で使用したり、塗布量を少なくするとともに金型を適正温度に保ったりする。   A hot water bath is an irregular cup-shaped pattern formed on the surface of a die-cast product, and the hot water flow pattern is a stripe-like gloss. These phenomena occur when the mold temperature is low or when the gas generated from the release agent becomes a high pressure and pushes the surface of the die-cast product or the amount of the release agent applied is large. As countermeasures, a mold release agent with good adhesion is used at a low concentration, or the coating amount is reduced and the mold is kept at an appropriate temperature.

湯境とは、溶湯が合流する部分で融合せず、残った境目で溶湯の入り方が不均一となり、一方の溶湯が先に凝固し境目として残る事象である。溶湯の流れをスムーズにし、溶湯や金型温度を上げることにより対処する。離型剤の塗布量を減らすことによって改善される場合もある。   The hot water boundary is an event in which the molten metal does not fuse at the portion where the molten metal joins, the molten metal enters in a nonuniform manner at the remaining boundary, and one molten metal solidifies first and remains as a boundary. This is dealt with by smoothing the flow of the molten metal and raising the temperature of the molten metal and mold. It may be improved by reducing the amount of the release agent applied.

焼き付きとは、ダイキャスト製品の表面が局所的過熱や金型の磨耗によって金型や鋳抜きピンの表面に溶着して、離型時に剥がれ取られることである。付着性のよい離型剤に変更したり、離型剤の塗布量を増やすことで改善可能である。   The seizure is that the surface of the die-cast product is welded to the surface of the mold or the core pin due to local overheating or wear of the mold, and is peeled off at the time of mold release. It can be improved by changing to a release agent with good adhesion or increasing the coating amount of the release agent.

かじりとは、ダイキャスト製品を取り出すとき、表面に生じた傷であり、キャビティ内の局部的過熱により溶湯の凝固が遅れ金型や鋳抜きピン表面に溶着をおこし焼き付いて、ダイキャスト製品の取り出し時に傷がつく。かじりは、離型剤の付着量が少ない時に発生しやすく、したがって離型剤の増量と高濃度化が解決方法である。付着性のよい離型剤に変更することもかじりの抑制になる可能性がある。   The galling is a scratch on the surface when the die-cast product is taken out, and the solidification of the molten metal is delayed due to local overheating in the cavity, and the die or cast pin surface is welded and baked to take out the die-cast product. Sometimes scratches. The galling is likely to occur when the amount of the release agent attached is small. Therefore, increasing the amount of release agent and increasing the concentration are solutions. Changing to a release agent with good adhesion may also reduce galling.

また、内部欠陥の巣は、金型内部の空気や離型剤から発するガスが溶湯内に残存したまま凝固することにより生じる空洞であり、比較的大きな空洞を巣、小さいスポンジ状のものはボロシティという場合もある。巣は離型剤の塗布量を減らしたり、低濃度化したり、さらにはガス発生の少ない離型剤に変更することにより抑制できる。   In addition, nests of internal defects are cavities generated by the solidification of the gas generated from the air and mold release agent inside the mold while remaining in the melt. In some cases. The nest can be suppressed by reducing the coating amount of the release agent, reducing the concentration, or changing to a release agent with less gas generation.

ここで、ダイキャスト金型には、例えば150〜400度の温度域があり、そのキャビティ内に合金を鋳込むため、離型剤も前記温度域で均一に付着させねばならない。離型剤の均一付着がうまくいかないと、前述したようなダイキャスト製品の内外欠陥が生じる場合がある。このような欠陥の問題を、離型剤の組成を変更して解決したり、あるいは、装置を工夫して解決したりしている。   Here, the die-cast mold has a temperature range of 150 to 400 degrees, for example, and in order to cast an alloy in the cavity, the mold release agent must be uniformly attached in the temperature range. If the uniform adhesion of the release agent is not successful, the above-described internal and external defects of the die cast product may occur. Such a defect problem is solved by changing the composition of the release agent, or by devising an apparatus.

ところで、大量生産工程では、作業時間が限られることから、塗布形式は塗布ガンあるいは塗布ノズルを1つまたは複数個設置しリンク式アームやロボットにより移動しながらあるいは固定したまま塗布することが多く、そのような装置が市販されている。   By the way, in a mass production process, since the working time is limited, the application type is often applied with one or a plurality of application guns or application nozzles being moved or fixed while being moved by a link type arm or robot. Such devices are commercially available.

例えば、特許文献1には、離型剤塗布装置の小型化とサイクルタイムの短縮を狙い、スプレーヘッドに対して可動式のスプレーノズルが提案されている。また、特許文献2には、離型剤を塗布する度に射出ユニットを移動させず、したがって稼動費用を削減でき、成形サイクルを短縮可能にするために、可動側金型に凹部を設け、この凹部から離型剤を供給する技術が開示されている。さらに、特許文献3では、移動タイプのスプレーヘッドの離型剤の塗布状況を改善するために、スプレーヘッドを三次元移動する改善案が提示されている。   For example, Patent Document 1 proposes a movable spray nozzle with respect to a spray head in order to reduce the size of the release agent coating apparatus and shorten the cycle time. Further, in Patent Document 2, the movable unit is provided with a concave portion so that the injection unit is not moved each time the mold release agent is applied, so that the operating cost can be reduced and the molding cycle can be shortened. A technique for supplying a release agent from a recess is disclosed. Further, Patent Document 3 proposes an improvement plan for moving the spray head three-dimensionally in order to improve the application state of the release agent of the moving type spray head.

特開平6−312251号公報JP-A-6-312251 特開2001−113352号公報JP 2001-113352 A 特開2006−334646号公報JP 2006-334646 A

前記背景技術で記述したように、リンク式アームやロボットによる塗布装置での離型剤塗布により離型剤の塗布状況は改善されているものの、ダイキャスト製品の形状が複雑だったり、狭小部に離型剤を塗布しなければならないときは、背景技術で述べた装置・方法では十分で無い。   As described in the background art above, although the application condition of the mold release agent has been improved by the application of the mold release agent with a link type arm or robot, the shape of the die cast product is complicated or narrow. When it is necessary to apply a release agent, the apparatus and method described in the background art are not sufficient.

例えば、特許文献1に記載された可動式スプレーノズルや特許文献3に記載されたスプレーヘッドの三次元移動では、毎回同じ狭小部に離型剤を塗布することは不可能である。つまり、スプレーノズルの移動軌跡を毎回正確に同一にすることは不可能であるし、毎回同じ位置・角度に正確に停止させることも不可能である。角度が1度ずれると50cm先では8.7mmのずれになってしまう。これでは複雑形状あるいは狭小部に離型剤を塗布することは困難である。   For example, in the three-dimensional movement of the movable spray nozzle described in Patent Document 1 and the spray head described in Patent Document 3, it is impossible to apply a release agent to the same narrow portion every time. That is, it is impossible to make the movement trajectory of the spray nozzle exactly the same every time, and it is impossible to accurately stop at the same position and angle every time. If the angle is shifted by 1 degree, the shift is 8.7 mm after 50 cm. This makes it difficult to apply a release agent to a complicated shape or a narrow portion.

また、特許文献2によれば、前記の型開き後スプレーヘッドを金型内に移動し離型剤を塗布する工程のかなりの部分を省略できるため、サイクルタイム短縮に効果があると考えられる。しかし、複雑な形状のダイキャスト製品のキャビティは、当然のことながら複雑な形状をなしており、そのキャビティに均一に離型剤を塗布するには、金型内に複数の離型剤供給路を設けなければならず、必然的に金型に多数の孔を窄孔することになってしまう。仮に、キャビティに窄孔した場合は、不完全ダイキャスト製品の製造や金型の寿命短縮につながってしまう。したがって、複雑形状のダイキャスト製品には応用できない。さらに、この方式は、スプル孔、ランナ溝、ゲート孔が必須の主にマグネシウム合金の射出成形法への離型剤塗布に関するものであり、特殊な鋳造法への離型剤塗布提案となっている。また、金型の高熱部、例えばキャビティにつらなるゲート部は金型全体でも最高温部であるが、ここを早期冷却することは、ワークの品質向上やサイクルタイムの短縮に大きく貢献する。   Further, according to Patent Document 2, it is considered that a considerable part of the process of moving the spray head after opening the mold into the mold and applying the release agent can be omitted, which is effective in shortening the cycle time. However, the cavity of a die-cast product having a complicated shape naturally has a complicated shape, and in order to uniformly apply a release agent to the cavity, a plurality of release agent supply paths are provided in the mold. Inevitably, a large number of holes are confined in the mold. If the hole is confined in the cavity, it will lead to the manufacture of incomplete die-cast products and shorten the life of the mold. Therefore, it cannot be applied to complex-shaped die-cast products. In addition, this method is related to the release agent application to the injection molding method of magnesium alloy, which is essential for sprue holes, runner grooves, and gate holes. Yes. In addition, the high temperature part of the mold, for example, the gate part connected to the cavity is the highest temperature part in the entire mold, but early cooling greatly contributes to the improvement of the work quality and the reduction of the cycle time.

本発明は、キャビティの形状が複雑であったり、キャビティが狭小部を有している場合であっても、離型剤をキャビティに良好に塗布することが可能な離型剤塗布装置およびこれを用いた離型剤塗布方法を提供することを目的とする。   The present invention relates to a release agent coating apparatus capable of satisfactorily applying a release agent to a cavity even when the shape of the cavity is complicated or the cavity has a narrow portion. It aims at providing the used release agent coating method.

本発明の一実施形態を図面を参照して以下に説明する。   An embodiment of the present invention will be described below with reference to the drawings.

図1は、成形装置11を示すものである。この成形装置11は、具体的にはアルミニウム合金の成形品を成形するダイキャスト装置であり、ベースフレーム12と、ベースフレーム12上の一端側に固定状態で載置されたリンクハウジング13と、ベースフレーム12上の他端側に固定状態で載置された固定盤14と、これらリンクハウジング13および固定盤14の間に設けられた可動盤15とを有している。   FIG. 1 shows a molding apparatus 11. Specifically, this forming apparatus 11 is a die-cast apparatus for forming a molded product of an aluminum alloy, and includes a base frame 12, a link housing 13 mounted in a fixed state on one end side of the base frame 12, a base It has a fixed platen 14 mounted in a fixed state on the other end side on the frame 12, and a movable platen 15 provided between the link housing 13 and the fixed platen 14.

リンクハウジング13および固定盤14には、これらの上下左右の四隅をそれぞれ結ぶように四本のタイバー20が水平に延設されており、可動盤15は、上下左右の四隅にこれらタイバー20を挿通させている。よって、可動盤15は、これらタイバー20に沿ってスライドする。可動盤15とリンクハウジング13とはトグル機構21で連結されており、トグル機構21の型締シリンダ22の作動により可動盤15がリンクハウジング13に対して近接および離間し、その結果、可動盤15が固定盤14に対して離間および近接する。   Four tie bars 20 are horizontally extended in the link housing 13 and the fixed platen 14 so as to connect the four corners of the upper, lower, left and right sides, and the movable platen 15 is inserted into the four corners of the upper, lower, left and right sides. I am letting. Therefore, the movable platen 15 slides along these tie bars 20. The movable platen 15 and the link housing 13 are connected by a toggle mechanism 21, and the movable platen 15 approaches and separates from the link housing 13 by the operation of the mold clamping cylinder 22 of the toggle mechanism 21. As a result, the movable platen 15 Is spaced apart and close to the stationary platen 14.

固定盤14の可動盤15側には、四本のタイバー20の内側位置に、固定型25が固定されており、可動盤15の固定盤14側には、四本のタイバー20の内側位置に、可動型26が固定されている。トグル機構21の型締シリンダ22の作動により可動盤15が固定盤14側に移動すると固定型25と可動型26とが合わせ面同士を当接させる。   A fixed mold 25 is fixed to the inner side of the four tie bars 20 on the movable platen 15 side of the fixed platen 14, and the inner side of the four tie bars 20 is fixed to the fixed platen 14 side of the movable platen 15. The movable mold 26 is fixed. When the movable platen 15 moves to the fixed platen 14 side by the operation of the mold clamping cylinder 22 of the toggle mechanism 21, the fixed die 25 and the movable die 26 abut the mating surfaces.

固定型25と可動型26とは、このように合わせ面同士を当接させた型閉じ状態で、固定型25のキャビティ形成部30と可動型26のキャビティ形成部31とで成形品の形状のキャビティ32を形成することになる。また、トグル機構21の型締シリンダ22の作動により可動盤15が固定盤14とは反対側に移動すると可動型26と固定型25とが合わせ面同士を離間させる型開き状態となり、この型開き状態で、キャビティ32で成形された成形品の取り出しが可能となる。このとき、成形品は可動型26に保持されて固定型25から離れることになり、よって、可動型26が成形品が残存する保持型となり、固定型25が成形品が残存しない非保持型となる。   The fixed mold 25 and the movable mold 26 are in a mold closed state in which the mating surfaces are in contact with each other in this manner, and the shape of the molded product is determined by the cavity forming section 30 of the fixed mold 25 and the cavity forming section 31 of the movable mold 26. A cavity 32 will be formed. Further, when the movable platen 15 is moved to the opposite side of the fixed platen 14 by the operation of the mold clamping cylinder 22 of the toggle mechanism 21, the movable die 26 and the fixed die 25 are brought into a die open state in which the mating surfaces are separated from each other. In this state, the molded product molded in the cavity 32 can be taken out. At this time, the molded product is held by the movable die 26 and is separated from the fixed die 25. Therefore, the movable die 26 becomes a holding die where the molded product remains, and the fixed die 25 is a non-holding die where the molded product does not remain. Become.

可動型26と固定型25とが、型閉じ状態でキャビティ32を形成する金型33を構成することになり、この金型33と、可動型26と固定型25と四本のタイバー20とが金型装置34を構成する。なお、タイバー20は可動盤15を摺動させることになり、その結果、可動型26をタイバー20に沿って移動するように案内する。   The movable mold 26 and the fixed mold 25 constitute a mold 33 that forms the cavity 32 when the mold is closed. The mold 33, the movable mold 26, the fixed mold 25, and the four tie bars 20 are formed. A mold apparatus 34 is configured. The tie bar 20 causes the movable platen 15 to slide, and as a result, the movable die 26 is guided to move along the tie bar 20.

固定盤14の可動盤15とは反対側には、キャビティ32内に溶湯を射出する射出機構40が設けられている。また、可動盤15の固定盤14とは反対側にはキャビティ32に成形された成形品を可動型26から押し出す押出機構41が設けられている。なお、成形品は、自動車のオートマチックトランスミッション用の複数の油圧流路を切り替えるバルブユニットのハウジング等であり、複雑な流路が形成された形状をなしている。   An injection mechanism 40 that injects molten metal into the cavity 32 is provided on the opposite side of the fixed platen 14 to the movable platen 15. Further, an extrusion mechanism 41 is provided on the opposite side of the movable platen 15 to the fixed platen 14 to push out a molded product formed in the cavity 32 from the movable die 26. The molded product is a housing of a valve unit that switches a plurality of hydraulic flow paths for an automatic transmission of an automobile, and has a shape in which a complicated flow path is formed.

金型33の可動型26には、図2に示すように、可動型26の移動方向に沿って固定型25側に突出するガイドポスト18が、キャビティ形成部30とは離間した位置に形成されており、これに位置を合わせて、固定型25に、固定型25の移動方向に沿って可動型26とは反対側に凹むガイド穴19がキャビティ形成部30とは離間した位置に形成されている。可動型26および固定型25に形成されたこれらのガイドポスト18およびガイド穴19は、型閉じ途中から型閉じ状態になるまでキャビティから離れた位置で互いに摺動可能に嵌合する。言い換えれば、ガイドポスト18は可動型26の固定型25に対する移動を案内する。なお、ガイドポスト18およびガイド穴19のいずれか一方が可動型26に、他方が固定型25に設けられていれば良く、これらは金型の33の可動型26の型分割面の不都合とならない位置に設けられることになる。   As shown in FIG. 2, a guide post 18 that protrudes toward the fixed mold 25 along the moving direction of the movable mold 26 is formed on the movable mold 26 of the mold 33 at a position separated from the cavity forming portion 30. In alignment with this, a guide hole 19 that is recessed on the opposite side of the movable mold 26 along the moving direction of the fixed mold 25 is formed at a position separated from the cavity forming portion 30 in the fixed mold 25. Yes. These guide posts 18 and guide holes 19 formed in the movable mold 26 and the fixed mold 25 are slidably fitted to each other at a position away from the cavity until the mold is closed from the middle of the mold closing. In other words, the guide post 18 guides the movement of the movable mold 26 relative to the fixed mold 25. Any one of the guide post 18 and the guide hole 19 only needs to be provided on the movable die 26 and the other is provided on the fixed die 25. These do not inconvenience the mold dividing surface of the movable die 26 of the mold 33. Will be provided at the position.

ガイドポスト18内には、図2に示すように、金型33が型開き状態にあるとき、固定型25のキャビティ形成部30および可動型26のキャビティ形成部31のうちの設定された少なくとも一方(図示例ではキャビティ形成部31)に指向する離型剤塗布ノズル45と、この離型剤塗布ノズル45に離型剤を供給する離型剤供給流路46とが形成されている。   As shown in FIG. 2, at least one of the cavity forming portion 30 of the fixed die 25 and the cavity forming portion 31 of the movable die 26 is set in the guide post 18 when the mold 33 is in the mold open state. A release agent application nozzle 45 directed to the cavity forming portion 31 (in the illustrated example) and a release agent supply channel 46 for supplying the release agent to the release agent application nozzle 45 are formed.

離型剤塗布ノズル45は、ガイドポスト18の離型剤塗布ノズル45を除くガイドポスト本体51から着脱可能となっている。図3に示すように、離型剤塗布ノズル45は、ガイドポスト本体51の取付凹部52に嵌合させられた状態で、複数のボルト53の締結によってガイドポスト本体51に固定されることになり、この状態で、離型剤塗布ノズル45が離型剤供給流路46に連通する。また、ボルト53が緩められることで、離型剤塗布ノズル45は、ガイドポスト本体51から取り外し可能となる。その結果、離型剤塗布ノズル45は離型剤供給流路46から取り外し可能となっている。   The release agent application nozzle 45 is detachable from the guide post body 51 except the release agent application nozzle 45 of the guide post 18. As shown in FIG. 3, the release agent application nozzle 45 is fixed to the guide post body 51 by fastening a plurality of bolts 53 in a state of being fitted in the mounting recess 52 of the guide post body 51. In this state, the release agent application nozzle 45 communicates with the release agent supply channel 46. Further, the release agent application nozzle 45 can be detached from the guide post body 51 by loosening the bolt 53. As a result, the release agent application nozzle 45 can be detached from the release agent supply channel 46.

図2に示すように、離型剤供給流路46は、離型剤を圧送する離型剤供給源55およびエアを圧送するエア供給源56にケーブルベア等を介して接続されており、電磁バルブ57によって、離型剤供給源55に連通し且つエア供給源56に連通しない状態と、エア供給源56に連通し且つ離型剤供給源55に連通しない状態と、離型剤供給源55およびエア供給源56のいずれにも連通しない状態とに切り替えられる。よって、離型剤供給流路46は、離型剤塗布ノズル45にエアを供給するエア供給流路を兼用している。   As shown in FIG. 2, the release agent supply channel 46 is connected to a release agent supply source 55 that pumps the release agent and an air supply source 56 that pumps air through a cable bear or the like. A state where the valve 57 communicates with the release agent supply source 55 and does not communicate with the air supply source 56, a state where communication with the air supply source 56 does not communicate with the release agent supply source 55, and a release agent supply source 55. And the state where the air supply source 56 does not communicate with the air supply source 56. Therefore, the release agent supply channel 46 also serves as an air supply channel for supplying air to the release agent application nozzle 45.

離型剤供給源55、離型剤塗布ノズル45および離型剤供給流路46が、離型剤塗布装置61を構成しており、離型剤塗布装置61は、そのうちの離型剤塗布ノズル45および離型剤供給流路46が、金型装置34のガイドポスト18内に設けられている。   The release agent supply source 55, the release agent application nozzle 45, and the release agent supply flow path 46 constitute a release agent application device 61. The release agent application device 61 includes a release agent application nozzle. 45 and a release agent supply channel 46 are provided in the guide post 18 of the mold apparatus 34.

金型33には、図4、図5および図6に示すように、可動型26に、可動型26の移動方向とは異なる方向、具体的には可動型26の移動方向と直交する方向に移動する可動中子65が設けられている。この可動中子65は、エアシリンダ等のシリンダ装置66で駆動されて前進および後退する。可動中子65は、図6に示す型閉じ状態では前進しており、この状態でシリンダ装置66とは反対側のキャビティ形成部67が固定型25および可動型26とともにキャビティ32を形成する。可動中子65のキャビティ形成部67には、シリンダ装置66とは反対側に突出する穴部形成突起68が形成されており、穴部形成突起68は、成形品に可動型26の移動方向とは異なる方向の穴部を形成する。成形品の取り外し時にこの可動中子65が後退して穴部形成突起68を穴部から抜かないと成形品を取り外すことができない。つまり、この穴部はそのままでは型抜きができないアンダーカット部分となる。可動中子65には、キャビティ形成部67とは反対側に段部70が形成されており、固定型25には、この段部70の背面71に当接して可動中子65の後退を規制する押さえ面72が形成されている。   As shown in FIGS. 4, 5, and 6, the mold 33 is moved to the movable mold 26 in a direction different from the moving direction of the movable mold 26, specifically in a direction orthogonal to the moving direction of the movable mold 26. A movable core 65 that moves is provided. The movable core 65 is driven by a cylinder device 66 such as an air cylinder to move forward and backward. The movable core 65 moves forward in the mold closed state shown in FIG. 6, and in this state, the cavity forming portion 67 opposite to the cylinder device 66 forms the cavity 32 together with the fixed mold 25 and the movable mold 26. The cavity forming portion 67 of the movable core 65 is formed with a hole forming projection 68 that protrudes on the opposite side of the cylinder device 66, and the hole forming projection 68 is formed on the molded product in the moving direction of the movable die 26. Form holes in different directions. The movable core 65 is retracted when the molded product is removed, and the molded product cannot be removed unless the hole forming projection 68 is removed from the hole. That is, this hole becomes an undercut portion that cannot be punched as it is. A step 70 is formed on the movable core 65 on the side opposite to the cavity forming portion 67, and the fixed mold 25 abuts against the back surface 71 of the step 70 to restrict the retraction of the movable core 65. A pressing surface 72 is formed.

この押さえ面72は、金型33が型閉じ状態にあるとき、キャビティ32から離れた位置で可動中子65に覆われる固定型25の中子被覆部73の表面となっている。中子被覆部73は可動中子65を押さえるという機能を有する金型機能部位となっている。固定型25内には、この中子被覆部73の位置に、金型33が型開き状態にあるとき、固定型25のキャビティ形成部30および可動型26のキャビティ形成部31のうちの設定された少なくともいずれか一方(図示例ではキャビティ形成部30)に指向する離型剤塗布ノズル75が形成されており、固定型25内には、さらに、この離型剤塗布ノズル75に離型剤を供給する離型剤供給流路76が形成されている。   The pressing surface 72 is a surface of the core covering portion 73 of the fixed mold 25 that is covered by the movable core 65 at a position away from the cavity 32 when the mold 33 is in the mold closed state. The core covering portion 73 is a mold functional part having a function of pressing the movable core 65. In the fixed mold 25, when the mold 33 is in an open state, the cavity forming section 30 of the fixed mold 25 and the cavity forming section 31 of the movable mold 26 are set at the position of the core covering section 73. Further, a release agent application nozzle 75 directed to at least one of them (the cavity forming unit 30 in the illustrated example) is formed, and a release agent is further applied to the release agent application nozzle 75 in the fixed mold 25. A release agent supply channel 76 for supplying is formed.

この離型剤塗布ノズル95も、図示は略すが、可動型26の離型剤塗布ノズル95を除く可動型本体に対し着脱可能となっている。離型剤供給流路96も、ケーブルベア等を介して離型剤供給源55およびエア供給源56に接続されており、電磁バルブ99によって、離型剤供給源55に連通し且つエア供給源56に連通しない状態と、エア供給源56に連通し且つ離型剤供給源55に連通しない状態と、離型剤供給源55およびエア供給源56のいずれにも連通しない状態とに切り替えられる。よって、離型剤供給流路96も、離型剤塗布ノズル95にエアを供給するエア供給流路を兼用している。   Although not shown, the release agent application nozzle 95 is also detachable from the movable body excluding the release agent application nozzle 95 of the movable die 26. The release agent supply channel 96 is also connected to the release agent supply source 55 and the air supply source 56 via a cable bear or the like, and communicates with the release agent supply source 55 by an electromagnetic valve 99 and is also an air supply source. The state is not switched to the state 56, the state is not connected to the release agent supply source 55, and the state is not connected to either the release agent supply source 55 or the air supply source 56. Therefore, the release agent supply channel 96 also serves as an air supply channel for supplying air to the release agent application nozzle 95.

離型剤供給源55、離型剤塗布ノズル95および離型剤供給流路96も、上記した離型剤塗布装置61を構成しており、離型剤塗布装置61は、離型剤塗布ノズル95および離型剤供給流路96が、金型装置34の可動型26内に設けられている。具体的に、可動型26内の凹部86の位置に離型剤塗布ノズル95が設けられるとともに、可動型26内に離型剤供給流路96が設けられている。   The release agent supply source 55, the release agent application nozzle 95, and the release agent supply channel 96 also constitute the release agent application device 61 described above, and the release agent application device 61 includes the release agent application nozzle. 95 and a release agent supply channel 96 are provided in the movable mold 26 of the mold apparatus 34. Specifically, a release agent application nozzle 95 is provided at the position of the concave portion 86 in the movable mold 26, and a release agent supply channel 96 is provided in the movable mold 26.

図7および図8に示すように、搬送機構100が、型開きした状態で離間する固定型25と可動型26との間に上方から進入可能に設けられている。この搬送機構100は、押出機構41で押し出されることで可動型26から取り外された成形品Sを受け取って上方に搬送する。   As shown in FIGS. 7 and 8, the transport mechanism 100 is provided between the fixed mold 25 and the movable mold 26 that are separated from each other when the mold is opened, so that the transport mechanism 100 can enter from above. The transport mechanism 100 receives the molded product S removed from the movable die 26 by being pushed out by the extrusion mechanism 41 and transports it upward.

また、図9に示すように、別途の離型剤塗布装置102(他の離型剤塗布装置)が、型開きした状態で離間する固定型25と可動型26との間に側方から進入可能に設けられている。離型剤塗布装置102も、固定型25のキャビティ形成部30および可動型26のキャビティ形成部31に離型剤を塗布する。この離型剤塗布装置102には、離型剤を噴出可能な多数の離型剤塗布ノズル103と、エアを噴出可能な多数のエアノズル104とが個別に設けられている。   Further, as shown in FIG. 9, a separate release agent coating device 102 (another release agent coating device) enters from the side between the fixed mold 25 and the movable mold 26 that are separated when the mold is opened. It is provided as possible. The release agent application device 102 also applies the release agent to the cavity forming part 30 of the fixed mold 25 and the cavity forming part 31 of the movable mold 26. The release agent coating apparatus 102 is individually provided with a number of release agent application nozzles 103 capable of ejecting a release agent and a number of air nozzles 104 capable of ejecting air.

なお、離型剤塗布装置61と、他の離型剤塗布装置102とで、離型剤の濃度が異なっていても良い。具体的には、他の離型剤塗布装置102で塗布する離型剤を、水30に対し離型剤原液1の濃度とし、金型装置34内にある離型剤塗布装置61で塗布する離型剤を、水70に対し離型剤原液1とする。つまり、金型装置34内にある離型剤塗布装置61は、ピンポイントに確実に狙い打てるので濃度を下げることが可能であり、経済的にできる。また、比較的単純な構造の成型品でトラブルの可能性が低い場合は、他の離型剤塗布装置102の方を用いて、水50に対し離型剤原液1の濃度とし、狭小部が複雑であれば金型装置34内にある離型剤塗布補助装置61の離型剤を水30に対し離型剤原液1の濃度としたりする。これにより、カセット形式の離型剤塗布装置102側の離型剤費用を抑えることができる。   Note that the concentration of the release agent may be different between the release agent application device 61 and the other release agent application device 102. Specifically, the release agent applied by the other release agent application device 102 is applied at the concentration of the release agent stock solution 1 to the water 30 and applied by the release agent application device 61 in the mold device 34. Let the mold release agent be the mold release agent stock solution 1 with respect to the water 70. In other words, the release agent coating device 61 in the mold device 34 can reliably aim at the pinpoint, so that the concentration can be lowered and economical. If the molded product has a relatively simple structure and the possibility of trouble is low, the concentration of the release agent stock solution 1 is set to the water 50 using the other release agent application device 102, and the narrow portion is reduced. If it is complicated, the release agent of the release agent application auxiliary device 61 in the mold device 34 is set to the concentration of the release agent stock solution 1 with respect to the water 30. Thereby, the mold release agent cost by the side of the cassette type mold release agent coating apparatus 102 can be suppressed.

なお、金型装置34内に設けられる離型剤塗布装置61と、別途の離型剤塗布装置102とを設けたが、別途の離型剤塗布装置102を設けずに、金型装置34内に設けられる離型剤塗布装置61のみで離型剤を塗布することも可能である。逆に、離型剤塗布装置61に、離型剤塗布装置102や、ロボット式の離型剤塗布装置、リンクアーム式の離型剤塗布装置を適宜組み合わせて併用することも可能である。加えて、金型33の離型剤を塗布する位置や、他の機構との干渉等の設置条件等によっては、ガイドポスト18の離型剤塗布ノズル45および離型剤供給流路46と、押さえ面72の離型剤塗布ノズル75および離型剤供給流路76と、凸部85の離型剤塗布ノズル90および離型剤供給流路91と、凹部86の離型剤塗布ノズル95および離型剤供給流路96との中から、選択的に設けるものを選定しても良い。   Although the release agent application device 61 and the separate release agent application device 102 provided in the mold device 34 are provided, the separate release agent application device 102 is not provided. It is also possible to apply the release agent only by the release agent application device 61 provided in the apparatus. Conversely, the release agent application device 61, a robot type release agent application device, and a link arm type release agent application device can be used in combination as appropriate. In addition, depending on the position where the mold release agent is applied to the mold 33 and the installation conditions such as interference with other mechanisms, the release agent application nozzle 45 and the release agent supply channel 46 of the guide post 18, The release agent application nozzle 75 and the release agent supply channel 76 on the holding surface 72, the release agent application nozzle 90 and the release agent supply channel 91 on the convex portion 85, the release agent application nozzle 95 on the concave portion 86, and You may select what is provided selectively from the mold release agent supply flow path 96.

次に、離型剤塗布装置61を含む成形装置11、搬送機構100および離型剤塗布装置102からなる成形システムの離型剤塗布方法を含むいくつかの作動例を図10に示すタイムチャートに沿って説明する。   Next, several operation examples including a mold release agent application method of a molding system including the molding apparatus 11 including the release agent application apparatus 61, the transport mechanism 100, and the release agent application apparatus 102 are shown in the time chart of FIG. It explains along.

「第1作動例」
図10(a)に示すタイムチャートの第1作動例は、別途の離型剤塗布装置102が設けられており、これを使用する場合の作動例である。
"First operation example"
The first operation example of the time chart shown in FIG. 10A is an operation example in which a separate release agent coating apparatus 102 is provided and used.

型閉じされた金型33のキャビティ32内に溶湯を注入する工程が行われた後、システム制御部は、トグル機構21により可動型26を固定型25から離間する方向に移動させて金型33を型開きする工程を開始させる(t0時点)。この型開き工程の終了(t2時点)の前に、システム制御部は、離型剤塗布装置61の電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものから固定型25への離型剤の塗布を開始させる(t1時点)。つまり、可動型26および固定型25のうち成形品Sが残存しない固定型25側に、離型剤供給流路46,76,91,96のうちの設定された少なくともいずれか一つを介して離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものから、離型剤を塗布する工程を開始させる。システム制御部は、型開きが終了すると同時に、可動型26と固定型25との間への搬送機構100の下降を開始させる(t2時点)。つまり、成形品Sを成形品Sが残存する可動型26から取り外して搬送する工程を開始させる。   After the step of injecting the molten metal into the cavity 32 of the mold 33 which is closed, the system control unit moves the movable mold 26 in the direction away from the fixed mold 25 by the toggle mechanism 21 and moves the mold 33. The process of opening the mold is started (at time t0). Prior to the end of the mold opening process (at time t2), the system control unit switches at least one of the set electromagnetic valves 57, 79, 92, and 99 of the release agent coating device 61 to release the mold. Of the mold application nozzles 45, 75, 90, and 95, the one that is directed to the fixed mold 25 is started to apply the release agent to the fixed mold 25 (at time t1). That is, of the movable mold 26 and the fixed mold 25, the fixed mold 25 side where the molded product S does not remain is provided via at least one of the set release agent supply channels 46, 76, 91, 96. The step of applying the release agent is started from the release agent application nozzle 45, 75, 90, 95 which is directed to the fixed die 25. The system control unit starts to lower the transport mechanism 100 between the movable mold 26 and the fixed mold 25 at the same time as the mold opening is completed (at time t2). That is, the process of removing and transporting the molded product S from the movable mold 26 where the molded product S remains is started.

この搬送機構100の下降が終了すると、システム制御部は、押出機構41により成形品Sの押し出しを含む成形品Sの取り出しを開始させるとともに、電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものからエアを固定型25へ噴出させる(t3時点)。所定時間エアを固定型25へ噴出させると、システム制御部は、電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替えることにより、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものへのエア供給を停止させる(t4時点)。   When the lowering of the transport mechanism 100 is completed, the system control unit starts taking out the molded product S including the extrusion of the molded product S by the push-out mechanism 41, and is set among the electromagnetic valves 57, 79, 92, and 99. Then, at least one of them is switched, and air is jetted from the release agent application nozzles 45, 75, 90, 95 directed to the fixed mold 25 to the fixed mold 25 (at time t3). When air is ejected to the fixed mold 25 for a predetermined time, the system control unit switches at least one of the electromagnetic valves 57, 79, 92, and 99 to switch the release agent application nozzles 45 and 75. , 90, 95, the air supply to the fixed die 25 is stopped (at time t4).

上記のようにして押出機構41により押し出された成形品Sを搬送機構100により受け取ることで成形品Sの取り出しが終了すると、システム制御部は、搬送機構100の上昇を開始させる(t5時点)。搬送機構100の上昇中、搬送機構100の上昇の終了(t7時点)の前に、システム制御部は、可動型26と固定型25との間への、離型剤塗布装置102の横からの挿入を開始させる(t6時点)。つまり、成形品Sをこれが残存する可動型26から取り外して搬送する工程が完了する前に、他の離型剤塗布装置102を型開きされた固定型25と可動型26との間に挿入する。そして、離型剤塗布装置102の挿入が終了すると、システム制御部は、離型剤塗布装置102から離型剤の可動型26への塗布を開始させる(t8時点)。   When the removal of the molded product S is completed by receiving the molded product S extruded by the extrusion mechanism 41 as described above by the transport mechanism 100, the system control unit starts raising the transport mechanism 100 (at time t5). During the ascent of the transport mechanism 100, before the end of the lift of the transport mechanism 100 (at time t7), the system control unit moves from the side of the release agent coating apparatus 102 between the movable mold 26 and the fixed mold 25. Insertion is started (time t6). That is, before the step of removing and transporting the molded product S from the remaining movable mold 26 is completed, another release agent coating device 102 is inserted between the fixed mold 25 and the movable mold 26 that are opened. . When the insertion of the release agent application device 102 is completed, the system control unit starts application of the release agent from the release agent application device 102 to the movable mold 26 (at time t8).

Air is ejected from the coating apparatus 102 to the movable mold 26 (at time t9). When air is ejected to the movable mold 26 for a predetermined time, the system control unit stops the ejection of the air from the release agent coating apparatus 102 to the movable mold 26 and at the same time, retracts the release agent coating apparatus 102 to the side. Start (time t10). When the retraction of the release agent coating apparatus 102 is completed, the system control unit starts closing the mold 33 that brings the movable mold 26 close to the fixed mold 25 by the toggle mechanism 21 (at time t11). When the mold 33 is closed (at time t12), the system control unit causes the injection device 40 to inject the molten metal into the cavity 32 to perform the next molding.

型閉じされた金型33のキャビティ32内に溶湯を注入する工程が行われた後、システム制御部は、トグル機構21により可動型26を固定型25から離間する方向に移動させて金型33を型開きする工程を開始させる(t0時点)。この型開き工程の終了(t2時点)の前に、システム制御部は、離型剤塗布装置61の電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものから固定型25への離型剤の塗布を開始させる(t1時点)。つまり、可動型26および固定型25のうち成形品Sが残存しない固定型25側に、離型剤供給流路46,76,91,96のうちの設定された少なくともいずれか一つを介して離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものから、離型剤を塗布する工程を開始させる。システム制御部は、型開きが終了すると同時に、可動型26と固定型25との間への搬送機構100の下降を開始させる(t2時点)。つまり、成形品Sを成形品Sが残存する可動型26から取り外して搬送する工程を開始させる。   After the step of injecting the molten metal into the cavity 32 of the mold 33 which is closed, the system control unit moves the movable mold 26 in the direction away from the fixed mold 25 by the toggle mechanism 21 and moves the mold 33. The process of opening the mold is started (at time t0). Prior to the end of the mold opening process (at time t2), the system control unit switches at least one of the set electromagnetic valves 57, 79, 92, and 99 of the release agent coating device 61 to release the mold.

The step of applying the release agent is started from the release agent application nozzle 45, 75, 90, 95 which is directed to the fixed die 25. The system control unit starts to lower the transport mechanism 100 between the movable mold 26 and the fixed mold 25 at the same time as the mold opening is completed (at time t2). That is, the process of removing and transporting the molded product S from the movable mold 26 where the molded product S remains is started.

この搬送機構100の下降が終了すると、システム制御部は、押出機構41により成形品Sの押し出しを含む成形品Sの取り出しを開始させるとともに、電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものからエアを固定型25へ噴出させる(t3時点)。所定時間エアを固定型25へ噴出させると、システム制御部は、電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替えることにより、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものへのエア供給を停止させる(t4時点)。   When the lowering of the transport mechanism 100 is completed, the system control unit starts taking out the molded product S including the extrusion of the molded product S by the push-out mechanism 41, and is set among the electromagnetic valves 57, 79, 92, and 99. Then, at least one of them is switched, and air is jetted from the release agent application nozzles 45, 75, 90, 95 directed to the fixed mold 25 to the fixed mold 25 (at time t3). When air is ejected to the fixed mold 25 for a predetermined time, the system control unit switches at least one of the electromagnetic valves 57, 79, 92, and 99 to switch the release agent application nozzles 45 and 75. , 90, 95, the air supply to the fixed die 25 is stopped (at time t4).

上記のようにして押出機構41により押し出された成形品Sを搬送機構100により受け取ることで成形品Sの取り出しが終了すると、システム制御部は、搬送機構100の上昇を開始させる(t5時点)。搬送機構100の上昇中、搬送機構100の上昇の終了(t7時点)の前に、システム制御部は、可動型26と固定型25との間への、離型剤塗布装置102の横からの挿入を開始させる(t6時点)。つまり、成形品Sをこれが残存する可動型26から取り外して搬送する工程が完了する前に、他の離型剤塗布装置102を型開きされた固定型25と可動型26との間に挿入する。そして、離型剤塗布装置102の挿入が完了する前に、システム制御部は、離型剤塗布装置102から離型剤の可動型26への塗布を開始させる(t21時点)。つまり、型開きされた固定型25と可動型26との間への他の離型剤塗布装置102の挿入が完了する前に、他の離型剤塗布装置102から離型剤を塗布し始める。   When the removal of the molded product S is completed by receiving the molded product S extruded by the extrusion mechanism 41 as described above by the transport mechanism 100, the system control unit starts raising the transport mechanism 100 (at time t5).

At the same time as the application of the release agent from the apparatus 102 to the movable mold 26 is completed, the ejection of air from the release agent application apparatus 102 to the movable mold 26 is started (at time t22). When air is ejected to the movable mold 26 for a predetermined time, the system control unit stops the ejection of the air from the release agent coating apparatus 102 to the movable mold 26 and at the same time starts to retract the release agent coating apparatus 102 to the side.

型閉じされた金型33のキャビティ32内に溶湯を注入する工程が行われた後、システム制御部は、トグル機構21により可動型26を固定型25から離間する方向に移動させて金型33を型開きする工程を開始させる(t0時点)。この型開き工程の終了(t2時点)の前に、システム制御部は、離型剤塗布装置61の電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものから固定型25への離型剤の塗布を開始させる(t1時点)。つまり、可動型26および固定型25のうち成形品Sが残存しない固定型25側に、離型剤供給流路46,76,91,96のうちの設定された少なくともいずれか一つを介して離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものから、離型剤を塗布する工程を開始させる。システム制御部は、型開きが終了すると同時に、可動型26と固定型25との間への搬送機構100の下降を開始させる(t2時点)。つまり、成形品Sを成形品Sが残存する可動型26から取り外して搬送する工程を開始させる。   After the step of injecting the molten metal into the cavity 32 of the mold 33 which is closed, the system control unit moves the movable mold 26 in the direction away from the fixed mold 25 by the toggle mechanism 21 and moves the mold 33. The process of opening the mold is started (at time t0). Prior to the end of the mold opening process (at time t2), the system control unit switches at least one of the set electromagnetic valves 57, 79, 92, and 99 of the release agent coating device 61 to release the mold. Of the mold application nozzles 45, 75, 90, and 95, the one that is directed to the fixed mold 25 is started to apply the release agent to the fixed mold 25 (at time t1). That is, of the movable mold 26 and the fixed mold 25, the fixed mold 25 side where the molded product S does not remain is provided via at least one of the set release agent supply channels 46, 76, 91, 96. The step of applying the release agent is started from the release agent application nozzle 45, 75, 90, 95 which is directed to the fixed die 25. The system control unit starts to lower the transport mechanism 100 between the movable mold 26 and the fixed mold 25 at the same time as the mold opening is completed (at time t2). That is, the process of removing and transporting the molded product S from the movable mold 26 where the molded product S remains is started.

この搬送機構100の下降が終了すると、システム制御部は、押出機構41により成形品Sの押し出しを含む成形品Sの取り出しを開始させるとともに、電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものからエアを固定型25へ噴出させる(t3時点)。所定時間エアを固定型25へ噴出させると、システム制御部は、電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替えることにより、離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものへのエア供給を停止させる(t4時点)。   When the lowering of the transport mechanism 100 is completed, the system control unit starts taking out the molded product S including the extrusion of the molded product S by the push-out mechanism 41, and is set among the electromagnetic valves 57, 79, 92, and 99. Then, at least one of them is switched, and air is jetted from the release agent application nozzles 45, 75, 90, 95 directed to the fixed mold 25 to the fixed mold 25 (at time t3). When air is ejected to the fixed mold 25 for a predetermined time, the system control unit switches at least one of the electromagnetic valves 57, 79, 92, and 99 to switch the release agent application nozzles 45 and 75. , 90, 95, the air supply to the fixed die 25 is stopped (at time t4).

上記のようにして押出機構41により押し出された成形品Sを搬送機構100により受け取ることで成形品Sの取り出しが終了すると、システム制御部は、搬送機構100の上昇を開始させると同時に、離型剤塗布装置61の電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの可動型26に指向するものから可動型26への離型剤の塗布を開始させる(t5時点)。つまり、成形品Sが取り外された可動型26側に離型剤供給流路46,76,91,96のうちの設定された少なくとも一つを介して離型剤塗布ノズル45,75,90,95のうちの可動型26に指向するものから離型剤を噴出する工程を開始させる。搬送機構100の上昇が終了する(t31時点)後のタイミングで、システム制御部は、離型剤塗布装置61の電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布ノズル45,75,90,95のうちの可動型26に指向するものからのエアの可動型26への噴出を開始させる(t32時点)。つまり、離型剤噴出後に離型剤供給流路46,76,91,96のうちの設定された少なくとも一つを介して離型剤塗布ノズル45,75,90,95のうちの可動型26に指向するものにエアを供給する工程を開始させる。   When the removal of the molded product S is completed by receiving the molded product S pushed out by the extrusion mechanism 41 as described above by the transport mechanism 100, the system control unit starts raising the transport mechanism 100 and at the same time releasing the mold. Switching at least one of the set electromagnetic valves 57, 79, 92, 99 of the agent coating device 61 and directing it to the movable mold 26 of the release agent coating nozzles 45, 75, 90, 95 To start application of the release agent to the movable mold 26 (at time t5). That is, the release agent application nozzles 45, 75, 90, through at least one of the release agent supply channels 46, 76, 91, 96 on the movable die 26 side from which the molded product S is removed. The step of ejecting the release agent from the one directed to the movable mold 26 out of 95 is started. At the timing after the lifting of the transport mechanism 100 ends (time t31), the system control unit turns on at least one of the set electromagnetic valves 57, 79, 92, 99 of the release agent coating device 61. Switching and release of air from the release agent coating nozzles 45, 75, 90, 95 directed to the movable mold 26 to the movable mold 26 is started (at time t32). That is, the movable mold 26 of the release agent application nozzles 45, 75, 90, 95 is passed through at least one of the release agent supply channels 46, 76, 91, 96 after the release of the release agent. The process of supplying air to the one directed to

所定時間エアを可動型26へ噴出させると、システム制御部は、離型剤塗布装置61の電磁バルブ57,79,92,99のうちの設定された少なくともいずれか一つを切り替え、離型剤塗布装置61からエアの可動型26への噴出を終了させる。それと同時に、システム制御部は、トグル機構21により可動型26を固定型25に近接させる金型33の型閉じを開始させる(t33時点)。金型33の型閉じが終了する(t34時点)と、次の成形を行うべく射出装置40からキャビティ32に溶湯を注入させる。   When air is ejected to the movable mold 26 for a predetermined time, the system control unit switches at least one of the set electromagnetic valves 57, 79, 92, and 99 of the mold release agent coating device 61 to release the mold release agent. The ejection of air from the coating device 61 to the movable mold 26 is terminated. At the same time, the system control unit starts closing the mold 33 that brings the movable mold 26 close to the fixed mold 25 by the toggle mechanism 21 (at time t33). When the mold 33 is closed (at time t34), the molten metal is injected into the cavity 32 from the injection device 40 to perform the next molding.

図10(d)は、比較のために示す離型剤塗布装置61を持たない従来の装置のタイムチャートであり、以下、これについて説明する。   FIG. 10D is a time chart of a conventional apparatus that does not have the release agent coating apparatus 61 shown for comparison, and this will be described below.

型閉じされた金型33のキャビティ32内に溶湯を注入する工程が行われた後、システム制御部は、トグル機構21により可動型26を固定型25から離間する方向に移動させて金型33を型開きする工程を開始させる(t0時点)。そして、この型開き工程が終了すると同時に、可動型26と固定型25との間への搬送機構100の下降を開始させる(t41時点)。   After the step of injecting the molten metal into the cavity 32 of the mold 33 which is closed, the system control unit moves the movable mold 26 in the direction away from the fixed mold 25 by the toggle mechanism 21 and moves the mold 33. The process of opening the mold is started (at time t0). And simultaneously with completion | finish of this type | mold opening process, the fall of the conveyance mechanism 100 between the movable mold | type 26 and the fixed mold | type 25 is started (time t41).

この搬送機構100の下降が終了すると、システム制御部は、押出機構41により成形品Sの押し出しを含む成形品Sの取り出しを開始させる(t42時点)。押出機構41により押し出された成形品Sを搬送機構100により受け取ることで成形品Sの取り出しが終了すると、システム制御部は、搬送機構100の上昇を開始させる(t43時点)。搬送機構100の上昇が終了すると、可動型26と固定型25との間への、離型剤塗布装置102の横からの挿入を開始させる(t44時点)。離型剤塗布装置102の横からの挿入が完了すると、離型剤塗布装置102から離型剤の可動型26への塗布を開始させる(t45時点)。   When the lowering of the transport mechanism 100 is completed, the system control unit causes the extrusion mechanism 41 to start taking out the molded product S including the extrusion of the molded product S (at time t42). When the removal of the molded product S is completed by receiving the molded product S pushed out by the extrusion mechanism 41 by the transport mechanism 100, the system control unit starts to raise the transport mechanism 100 (at time t43). When the raising of the transport mechanism 100 is completed, insertion of the release agent coating apparatus 102 from the side between the movable mold 26 and the fixed mold 25 is started (at time t44). When the insertion of the release agent application device 102 from the side is completed, the release agent application device 102 starts application of the release agent to the movable die 26 (at time t45).

所定時間離型剤を可動型26へ噴出させると、システム制御部は、離型剤塗布装置102から離型剤の可動型26への塗布を停止させ、離型剤塗布装置102からエアの可動型26への噴出を開始させる(t46時点)。所定時間エアを可動型26へ噴出させると、離型剤塗布装置102からエアの可動型26へ噴出を停止させ、離型剤塗布装置102の横への退避を開始させる(t47時点)。そして、離型剤塗布装置102の退避が終了すると、システム制御部は、トグル機構21により可動型26を固定型25に近接させる金型33の型閉じを開始させる(t48時点)。金型33の型閉じが終了する(t49時点)と、次の成形を行うべく射出装置40からキャビティ32に溶湯を注入させる。   When the release agent is ejected to the movable mold 26 for a predetermined time, the system control unit stops the application of the release agent from the release agent coating apparatus 102 to the movable mold 26, and the air is moved from the release agent coating apparatus 102. The ejection to the mold 26 is started (at time t46). When air is ejected to the movable mold 26 for a predetermined time, the ejection of the air from the release agent coating apparatus 102 to the movable mold 26 is stopped, and the retraction of the release agent coating apparatus 102 to the side is started (at time t47). When the withdrawal of the release agent coating apparatus 102 is completed, the system control unit starts closing the mold 33 that brings the movable mold 26 close to the fixed mold 25 by the toggle mechanism 21 (at time t48). When the mold 33 is closed (at time t49), the molten metal is injected into the cavity 32 from the injection device 40 to perform the next molding.

なお、図11に示すように、ガイドポスト18に設けられた離型剤塗布ノズル45を以下のように変更することも可能である。   As shown in FIG. 11, the release agent application nozzle 45 provided on the guide post 18 can be changed as follows.

離型剤塗布ノズル45を一つの離型剤供給流路46に対して複数設けても良い。   A plurality of release agent application nozzles 45 may be provided for one release agent supply channel 46.

また、離型剤塗布ノズル45の離型剤の噴出方向を可変としても良い。具体的には、一方の離型剤塗布ノズル45をガイドポスト18に沿う基端分割体110と、この基端分割体110に繋がる中間分割体111と、この中間分割体111に繋がる噴出側の先端分割体112とに分ける。そして、基端分割体110に対し中間分割体111を、基端分割体111を中心に回転可能に連結する。また、中間分割体111に対し先端分割体112を基端分割体110と直交する方向に沿う軸回りに回転可能に連結するとともに六角ボルト113で角度を固定可能とする。また、他方の離型剤塗布ノズル45を離型剤供給流路46への接続側の基端分割体120と、噴出側の先端分割体121とに分けるとともに、これらをシリコンチューブやナイロンチューブ等の可撓性耐熱チューブあるいは蛇腹の耐熱チューブ等のチューブ122で結ぶ。そして、分割体121を分割体112に固定する。これにより、噴出側の先端分割体112,121が一体に角度を変更する。なお、先端分割体112,121同士は内部の流路を合流させており、離型剤供給流路46から供給された離型剤およびエアを先端分割体112,121の両方から噴出させる。   The ejection direction of the release agent from the release agent application nozzle 45 may be variable. Specifically, one of the release agent application nozzles 45 is arranged on the base end divided body 110 along the guide post 18, the intermediate divided body 111 connected to the base end divided body 110, and the ejection side connected to the intermediate divided body 111. Divided into a tip split body 112. Then, the intermediate divided body 111 is connected to the proximal end divided body 110 so as to be rotatable around the proximal end divided body 111. In addition, the distal end divided body 112 is connected to the intermediate divided body 111 so as to be rotatable about an axis along a direction orthogonal to the proximal end divided body 110 and the angle can be fixed with a hexagon bolt 113. Further, the other release agent application nozzle 45 is divided into a base end split body 120 on the connection side to the release agent supply flow path 46 and a tip end split body 121 on the ejection side, and these are divided into a silicon tube, a nylon tube or the like. And a flexible heat resistant tube or a bellows heat resistant tube. Then, the divided body 121 is fixed to the divided body 112. Thereby, the tip-end divided bodies 112 and 121 on the ejection side integrally change the angle. The tip split bodies 112 and 121 are joined together in the internal flow path, and the release agent and air supplied from the release agent supply flow path 46 are ejected from both of the tip split bodies 112 and 121.

以上に述べた本実施形態によれば、離型剤塗布ノズル45,75,90,95が、金型装置34内に設けられているため、金型装置34外に設けられている場合とは異なる方向から、型開き状態にある金型33のキャビティ形成部30,31に離型剤を噴射することができる。したがって、キャビティ32の形状が複雑であったり、キャビティ32が狭小部を有している場合であっても、離型剤をキャビティ32に良好に塗布することが可能となる。よって、合理的に離型剤を塗布することができ、優れた成形品の離型性を実現可能となって、成形品の品質向上および成形コストの低減を図ることができる。つまり、離型剤の塗布を効率化し、離型剤の必要な部位に確実に塗布する一方、離型剤塗布時間を短縮し、品質・コスト面で競争力のある成型品を得ることができる。また、離型剤塗布ノズル45,75,90,95および離型剤供給流路46,76,91,96が金型装置34内に設けられているため、これらが可動型26の移動に干渉することはなく、故障を生じ難い。また、離型剤塗布装置61に、離型剤塗布装置102や、ロボット式の離型剤塗布装置、リンクアーム式の離型剤塗布装置を適宜組み合わせて併用することにより、現有設備になるべく手をかけず、合理的に離型剤を塗布することができ、少額追加投資で優れた成形品の離型性を実現可能となる。   According to the present embodiment described above, since the release agent application nozzles 45, 75, 90, and 95 are provided in the mold apparatus 34, the case where the release agent application nozzles 45, 75, 90, and 95 are provided outside the mold apparatus 34. From a different direction, the mold release agent can be injected into the cavity forming portions 30 and 31 of the mold 33 in the mold open state. Therefore, it is possible to satisfactorily apply the release agent to the cavity 32 even when the shape of the cavity 32 is complicated or the cavity 32 has a narrow portion. Therefore, it is possible to apply the release agent reasonably, and it is possible to realize excellent mold release properties, thereby improving the quality of the molded product and reducing the molding cost. In other words, the application of the release agent is made more efficient, and the release agent application time is surely applied, while the release agent application time is shortened, and a molded product that is competitive in terms of quality and cost can be obtained. . Further, since the release agent application nozzles 45, 75, 90, 95 and the release agent supply channels 46, 76, 91, 96 are provided in the mold apparatus 34, these interfere with the movement of the movable die 26. It is not likely to cause a failure. Further, by combining the release agent application device 61 with the release agent application device 102, the robot type release agent application device, and the link arm type release agent application device in combination as appropriate, it is possible to make the existing facilities as much as possible. Therefore, it is possible to apply a release agent reasonably, and to realize excellent mold release properties with a small additional investment.

離型剤塗布ノズル45および離型剤供給流路46がガイドポスト18内に設けられるため、金型装置34に元々必要なガイドポスト18に多少の追加加工を施せば良く、離型剤塗布ノズル45および離型剤供給流路46を金型装置34内に安価で容易に設けることができる。しかも、離型剤塗布ノズル45および離型剤供給流路46の構造も単純化できるため、故障し難くなり、メンテナンス性にも優れる。また、離型剤塗布ノズル45および離型剤供給流路46をガイドポスト18内に仕込むことで、特定部位に確実に離型剤を塗布できる。   Since the release agent application nozzle 45 and the release agent supply flow path 46 are provided in the guide post 18, it is sufficient to perform some additional processing on the guide post 18 that is originally required for the mold apparatus 34. 45 and the release agent supply channel 46 can be easily and inexpensively provided in the mold apparatus 34. In addition, since the structure of the release agent application nozzle 45 and the release agent supply channel 46 can be simplified, it becomes difficult to break down and is excellent in maintainability. Further, by supplying the release agent application nozzle 45 and the release agent supply channel 46 into the guide post 18, the release agent can be reliably applied to a specific part.

金型33の型閉じ状態で可動中子65に覆われる中子被覆部73の位置に離型剤塗布ノズル75が設けられるとともに、金型33内に離型剤供給流路76が設けられているため、ガイドポスト18への離型剤塗布ノズル45の設置と同様、金型33に多少の追加加工を施せば良く、離型剤塗布ノズル75および離型剤供給流路76を、邪魔にならない金型装置34内に安価で容易に設けることができる。しかも、離型剤塗布ノズル75および離型剤供給流路76の構造も単純化できるため、故障し難くなり、メンテナンス性にも優れる。加えて、金型33内の型閉じ状態でキャビティ32を形成しない位置を有効利用して離型剤塗布ノズル75および離型剤供給流路76を設けることができる。つまり、単純な成型品の金型の型分割面は平面となっているが、成型品が複雑形状となった場合、例えばアンダーカットとなった場合は、そのままでは、型抜きができないため崩壊中子や可動中子が用いられる。可動中子の場合は、可動中子の押さえ面が型分割面に対して直角等交差して形成されたりする。このような可動中子65の押さえ面72等の金型機能部位に離型剤塗布ノズル75を設置し、これに連なる離型剤供給経路76を金型33内に設ければ、離型剤の塗布が可能となる。   A mold release agent application nozzle 75 is provided at a position of the core covering portion 73 covered with the movable core 65 in a mold closed state of the mold 33, and a mold release agent supply channel 76 is provided in the mold 33. Therefore, similar to the installation of the release agent application nozzle 45 on the guide post 18, it is sufficient to apply some additional processing to the mold 33, and the release agent application nozzle 75 and the release agent supply channel 76 are obstructed. It can be easily provided at a low cost in the mold apparatus 34 that does not become necessary. In addition, since the structure of the release agent application nozzle 75 and the release agent supply channel 76 can be simplified, it becomes difficult to break down and is excellent in maintainability. In addition, it is possible to provide the release agent application nozzle 75 and the release agent supply flow path 76 by effectively utilizing the position in the mold 33 where the cavity 32 is not formed in the closed state. In other words, the mold dividing surface of a simple molded product mold is flat, but if the molded product has a complicated shape, for example, if it is undercut, it cannot be removed as it is and is collapsing. A child or a movable core is used. In the case of a movable core, the pressing surface of the movable core may be formed so as to intersect at right angles to the mold dividing surface. If the mold release agent application nozzle 75 is installed in the mold functional part such as the pressing surface 72 of the movable core 65 and the mold release agent supply path 76 connected thereto is provided in the mold 33, the mold release agent. Can be applied.

金型33には、型閉じ状態にあるときキャビティ32から離れた位置で互いに嵌合する凸部85および凹部86に、離型剤塗布ノズル90,95および離型剤供給流路91,96が設けられているため、金型33に多少の追加加工を施せば良く、離型剤塗布ノズル90,95および離型剤供給流路91,96を金型装置34内に安価で容易に設けることができる。しかも、離型剤塗布ノズル90,95および離型剤供給流路91,96の構造も単純化できるため、故障し難くなり、メンテナンス性にも優れる。加えて、金型33内の型閉じ状態でキャビティ32を形成しない位置を有効利用して離型剤塗布ノズル90,95および離型剤供給流路91,96を設けることができる。例えば、もともと存在するガイドポスト18や押さえ面72等の金型機能部位に加えてさらに離型剤を塗布したい場合や、ガイドポスト18や金型機能部位が利用できない場合に有効となる。   In the mold 33, release agent application nozzles 90 and 95 and release agent supply channels 91 and 96 are provided in a convex portion 85 and a concave portion 86 that are fitted to each other at a position away from the cavity 32 when the mold is closed. Therefore, the mold 33 may be subjected to some additional processing, and the release agent application nozzles 90 and 95 and the release agent supply channels 91 and 96 are easily and inexpensively provided in the mold apparatus 34. Can do. In addition, since the structure of the release agent application nozzles 90 and 95 and the release agent supply channels 91 and 96 can be simplified, it becomes difficult to break down and is excellent in maintainability. In addition, the release agent application nozzles 90 and 95 and the release agent supply channels 91 and 96 can be provided by effectively utilizing the positions in the mold 33 where the cavity 32 is not formed in the closed state. For example, this is effective when it is desired to apply a mold release agent in addition to the originally existing mold function parts such as the guide post 18 and the pressing surface 72, or when the guide post 18 and the mold function part cannot be used.

ガイドポスト18の離型剤塗布ノズル45、押さえ面72等の機能部位の離型剤塗布ノズル75、凸部85の離型剤塗布ノズル90および凹部86の離型剤塗布ノズル95を用いることで、離型剤を塗布する部位が多数ある場合に、離型剤を良好に塗布できることになる。   By using the release agent application nozzle 45 of the guide post 18, the release agent application nozzle 75 of the functional part such as the pressing surface 72, the release agent application nozzle 90 of the convex portion 85, and the release agent application nozzle 95 of the concave portion 86. The release agent can be applied satisfactorily when there are many parts to which the release agent is applied.

可動型26および固定型25のうち成形品が残存しない非保持型である固定型25側に、離型剤供給流路46,76,91,96のうちの設定された少なくとも一つを介して離型剤塗布ノズル45,75,90,95のうちの固定型25に指向するものから離型剤を噴出する工程と、成形品をこれが残存する保持型である可動型26から取り外して搬送する工程とを並行して行うことができ、金型装置34外に設けられている他の離型剤塗布装置102を型開きされた固定型25と可動型26との間に挿入して、該他の離型剤塗布装置102から、成形品が取り外された可動型26側に離型剤を噴出することができる。したがって、成形品を保持型である可動型26から取り外して搬送する工程と、非保持型である固定型25に離型剤を噴出する工程とをオーバーラップさせて並行処理することができ、サイクルタイムを短縮することが可能となる。また、既存のカセット形式やロボットによる離型剤塗布装置は用いるものの、離型剤塗布装置61のみでは離型剤を塗布できなかったあるいは離型剤塗布ノズルの位置ずれにより離型剤が塗布されなくなってしまった等という事象が発生しなくなる。また、既存設備に導入する際は現有設備に軽微な追加にとどまるため、長期間製造ラインを停止する必要もなく、追加投資も少なくてすむ。   Of the movable mold 26 and the fixed mold 25, the fixed mold 25 which is a non-holding mold in which no molded product remains is provided via at least one of the release agent supply channels 46, 76, 91, 96. A step of ejecting the release agent from the release agent application nozzles 45, 75, 90, 95 directed to the fixed die 25, and the molded product is removed from the movable die 26, which is the holding die, and conveyed. The process can be performed in parallel, and another mold release agent coating apparatus 102 provided outside the mold apparatus 34 is inserted between the fixed mold 25 and the movable mold 26 opened, The mold release agent can be ejected from the other mold release agent applicator 102 to the movable mold 26 side from which the molded product is removed. Therefore, the process of removing the molded product from the movable mold 26 that is the holding mold and transporting it and the process of ejecting the release agent to the stationary mold 25 that is the non-holding mold can be overlapped and processed in parallel. Time can be shortened. In addition, although a release agent coating device using an existing cassette type or robot is used, the release agent cannot be applied only by the release agent application device 61 or the release agent is applied due to the displacement of the release agent application nozzle. Events such as disappearing will not occur. In addition, when installed in existing equipment, only a minor addition to the existing equipment is required, so there is no need to shut down the production line for a long period of time and additional investment is reduced.

離型剤塗布装置61と、金型装置34外に設けられている他の離型剤塗布装置102とで離型剤の濃度が異なるため、離型剤塗布位置61,102に応じてより適正な濃度の離型剤を塗布することができる。つまり、離型剤を利用するのは、もとより成型品が金型33の内面に固着し取り出せないなどのトラブルを避けるためであり、カセット形式による離型剤塗布装置102に、金型装置34内にある離型剤塗布装置61を併用するため、この2系統で離型剤の濃度を変更することは、トラブルを避けるための有効な手段となる。加えて、濃度が低くても良い方については濃度を下げることで、離型剤費用を抑えることができる。   Since the concentration of the release agent is different between the release agent application device 61 and the other release agent application device 102 provided outside the mold device 34, it is more appropriate depending on the release agent application positions 61 and 102. It is possible to apply a release agent having a proper concentration. In other words, the release agent is used in order to avoid troubles such as the molded product sticking to the inner surface of the mold 33 and cannot be taken out. Therefore, changing the concentration of the release agent in these two systems is an effective means for avoiding trouble. In addition, if the concentration may be low, the release agent cost can be reduced by reducing the concentration.

成形品をこれが残存する保持型である可動型26から取り外して金型33外に搬送する工程が完了する前に、他の離型剤塗布装置102を型開きされた固定型25と可動型26との間に挿入するため、これらの工程をオーバーラップさせて並行処理することができ、サイクルタイムを短縮することが可能となる。なお、この場合、同じ側から双方の作業を行なうことは困難で、上記例のように、成型品の取り出しを成形装置11の上側から行い、離型剤塗布装置102を横から出し入れすると双方の干渉の心配が無く好ましい。   Before the step of removing the molded product from the movable mold 26 which is the holding mold where it remains and transporting it outside the mold 33 is completed, the other mold release agent applicator 102 is opened and the fixed mold 25 and the movable mold 26 are opened. Therefore, these processes can be overlapped and processed in parallel, and the cycle time can be shortened. In this case, it is difficult to perform both operations from the same side. As in the above example, when the molded product is taken out from the upper side of the molding apparatus 11 and the release agent coating apparatus 102 is taken in and out from the side, both of the operations are performed. There is no worry of interference, which is preferable.

他の離型剤塗布装置102において、型開きされた固定型25と可動型26との間への挿入が完了する前に離型剤を塗布し始めるため、他の離型剤塗布装置102の挿入と塗布とを並行して行うことになり、サイクルタイムを短縮することが可能となる。   In another mold release agent applicator 102, since the mold release agent starts to be applied before the insertion between the fixed mold 25 and the movable mold 26 opened is completed, Insertion and application are performed in parallel, and the cycle time can be shortened.

なお、本実施形態は上記の明細内容及び図面に示した例に限定されず、自明の範囲で変更可能である。例えば、上記実施形態ではアルミニウムのダイキャスト製法について述べたが、例えば、樹脂成形にこの技術を適用することも勿論可能である。   In addition, this embodiment is not limited to the example shown in said specification content and drawing, It can change in a self-evident range. For example, in the above embodiment, the aluminum die-casting method has been described, but it is of course possible to apply this technique to resin molding, for example.
