Description

本発明は、互いに対向させた固定金型と可動金型と所定の圧力下で型締めし、これらの金型の間に形成されたキャビティ内に溶融樹脂を充填して成形品を成形する射出成形に用いられる射出成形用金型の調整方法、及び、金型装置に関する。   The present invention is an injection in which a fixed mold and a movable mold opposed to each other are clamped under a predetermined pressure, and a molten resin is filled into a cavity formed between these molds to mold a molded product. The present invention relates to a method for adjusting an injection mold used for molding, and a mold apparatus.

特許文献１には、互いに対向させた固定金型と可動金型と所定の圧力下で型締めし、これらの金型の間に形成されたキャビティ内に溶融樹脂を充填して成形品を成形する射出成形の技術が開示されている。   In Patent Document 1, a fixed mold and a movable mold opposed to each other are clamped under a predetermined pressure, and a molded resin is molded by filling a cavity formed between these molds with a molten resin. An injection molding technique is disclosed.

特許文献１の図５や図６に示される射出成形の技術では、固定金型１及び可動金型２は、射出成形機の型締め部に互いに対向して配置された一対の取付板３，４のそれぞれに取り付けられている。固定金型１及び可動金型２は、油圧シリンダ５によって所定の圧力下（一例として、２０００〜４０００トン程度の圧力）で型締めされる。型締めにより、固定金型１と可動金型２との間にキャビティが形成される。成形品の射出成形は、キャビティ内に溶融樹脂を高圧で充填することによりなされる。そして、固定金型１と可動金型２とは、成形時にキャビティ内に充填される溶融樹脂の圧力によって開かないよう、溶融樹脂の圧力と同等又はそれ以上の圧力で締め付けられる必要がある。   In the injection molding technique shown in FIG. 5 and FIG. 6 of Patent Document 1, the fixed mold 1 and the movable mold 2 are a pair of mounting plates 3 disposed opposite to each other at a mold clamping portion of an injection molding machine. 4 is attached to each. The fixed mold 1 and the movable mold 2 are clamped by a hydraulic cylinder 5 under a predetermined pressure (for example, a pressure of about 2000 to 4000 tons). By the mold clamping, a cavity is formed between the fixed mold 1 and the movable mold 2. Injection molding of a molded product is performed by filling the cavity with molten resin at a high pressure. The fixed mold 1 and the movable mold 2 need to be clamped at a pressure equal to or higher than the pressure of the molten resin so as not to be opened by the pressure of the molten resin filled in the cavity during molding.

ここで、特許文献１に記載されているように、固定金型１や可動金型２における中央付近がパーティションライン面を開く方向に撓み、固定金型１や可動金型２の四隅がパーティションライン面を閉じる方向に撓んで、固定金型１と可動金型２と間に隙間６が生じることが一般に知られている。これは、例えば金型の構造、金型の厚さ、金型の材質、金型の型締めの構造、溶融樹脂の圧力を受ける受圧面積等によるものと考えられる。また、固定金型１や可動金型２の受圧面１ａ，２ａに配置される受圧プレート７が、隙間６の発生を助長してしまう。成形品の成形時には、この隙間６に溶融樹脂が侵入し、バリが発生してしまうことがある。   Here, as described in Patent Document 1, the vicinity of the center of the fixed mold 1 and the movable mold 2 is bent in the direction of opening the partition line surface, and the four corners of the fixed mold 1 and the movable mold 2 are the partition lines. It is generally known that a gap 6 is formed between the fixed mold 1 and the movable mold 2 by bending in the direction of closing the surface. This is considered to be due to the structure of the mold, the thickness of the mold, the material of the mold, the structure of the mold clamping, the pressure receiving area that receives the pressure of the molten resin, and the like. Further, the pressure receiving plates 7 arranged on the pressure receiving surfaces 1 a and 2 a of the fixed mold 1 and the movable mold 2 promote the generation of the gap 6. When molding a molded product, the molten resin may enter the gap 6 to generate burrs.

特許文献１には、固定金型１や可動金型２の成形時の予測撓み量を解析することと、その解析結果に基づいて取付板１１と金型１３，１４との間のシム１６や受圧面側の隙間を仮決定し金型の設計を修正することとを繰り返し、本決定された金型で成形された成形品のバリの状態を見ながらシムや隙間の状態をさらに微調整して金型の撓みによる成形製品のバリを防止することが記載されている。   Patent Document 1 discloses analyzing the predicted amount of deflection at the time of molding the fixed mold 1 and the movable mold 2, and based on the analysis result, the shim 16 between the mounting plate 11 and the molds 13 and 14, Repeatedly tentatively determining the clearance on the pressure-receiving surface side and correcting the mold design, and further adjusting the state of the shim and clearance while observing the state of burrs in the molded product molded with this determined mold It is described that the burr of the molded product due to the bending of the mold is prevented.

特開２００６−１８１７３６号公報JP 2006-181736 A

特許文献１に記載の技術は、取付板１１と金型１３，１４との間にシム１６が配置されていることを前提とするものである。このため、バリの状態を見ながらシム１６の厚み等の微調整を行う際には、大掛かりな金型１３，１４の分解が必要である。   The technique described in Patent Document 1 is based on the premise that a shim 16 is disposed between the mounting plate 11 and the molds 13 and 14. For this reason, when making fine adjustments such as the thickness of the shim 16 while observing the state of burrs, it is necessary to disassemble the large molds 13 and 14.

また、金型１３，１４のメンテナンスでパーティングライン面の補正をする際には、シム１６を取り外して行わなければならない。その際にも、大掛かりな金型１３，１４の分解が必要である。   Further, when correcting the parting line surface during the maintenance of the molds 13 and 14, the shim 16 must be removed. At that time, it is necessary to disassemble the dies 13 and 14 in a large scale.

さらに、シム１６は、取付板１１と金型１３，１４とに挟まれるよう一枚物となっている。このため、金型１３，１４の部位に応じた適切な撓みの補強を行えない。   Further, the shim 16 is a single piece so as to be sandwiched between the mounting plate 11 and the molds 13 and 14. For this reason, the reinforcement of the appropriate bending according to the site | part of the metal mold | die 13 and 14 cannot be performed.

加えて、シム１６は、溶融樹脂の射出圧や金型の型締め圧を受け、へたってコシがなくなる。このため、シム１６は、定期的に交換されなくてはならない。   In addition, the shim 16 receives the injection pressure of the molten resin and the mold clamping pressure of the mold, so that there is no stiffness. For this reason, the shim 16 must be replaced periodically.

本発明の目的は、射出成形時の金属の撓みによって発生するバリの抑制を簡単に行い、その効果を持続させることである。   An object of the present invention is to easily suppress burrs generated by bending of a metal during injection molding and to maintain the effect.

本発明の射出成形用金型の調整方法は、射出成形装置の型締め部に互いに対向して配置される一対の取付板に対し固定金型と可動金型とを互いに対向するよう取り付け、これらの金型を型締めして形成されるキャビティ内に溶融樹脂を射出して成形品を成形する射出成形に用いられる金型の調整方法であって、前記取付板において金型が取り付けられた面とは反対側の面に位置するプレートを配置する。   The method for adjusting an injection molding die according to the present invention is such that a fixed mold and a movable mold are attached to a pair of mounting plates arranged opposite to each other on a mold clamping portion of an injection molding device, and these A method for adjusting a mold used for injection molding in which a molten resin is injected into a cavity formed by clamping a mold of the mold to form a molded product, the surface of the mounting plate on which the mold is mounted Place a plate located on the opposite side of the plate.

本発明の金型装置は、射出成形装置の型締め部に配置され成形品の射出成形に用いられる金型装置であって、前記型締め部に着脱自在に取り付けられ、互いに対向して配置される一対の取付板と、互いに対向するよう前記一対の取付板に取り付けられ、溶融樹脂が射出されるキャビティを形成する固定金型及び可動金型と、前記一対の取付板の少なくとも一方に配置され、この取付板において金型が取り付けられた面とは反対側の面に取り付けられるプレートと、を備える。   A mold apparatus according to the present invention is a mold apparatus that is disposed in a mold clamping part of an injection molding apparatus and used for injection molding of a molded product, and is detachably attached to the mold clamping part and disposed opposite to each other. A pair of mounting plates, a fixed mold and a movable mold that are attached to the pair of mounting plates so as to face each other and form a cavity through which molten resin is injected, and are disposed on at least one of the pair of mounting plates. And a plate that is attached to a surface opposite to the surface on which the mold is attached in the attachment plate.

本発明によれば、取付板に対するプレートを調整することで、射出成形時の金属の撓みによって発生するバリの抑制を簡単に行い、その効果を持続させることができる。   According to the present invention, by adjusting the plate with respect to the mounting plate, it is possible to easily suppress the burrs generated due to the bending of the metal during the injection molding, and to maintain the effect.

図３は、金型装置１０２の側面断面図である。図４は、図３のＡ矢視図である。図４では、締結部材１０５ｂは省略されている。金型装置１０２は、第１の取付板１０３と、第２の取付板１０４と、固定金型１０５と、可動金型１０６と、受圧材１０７とを備える。   FIG. 3 is a side sectional view of the mold apparatus 102. 4 is a view taken in the direction of arrow A in FIG. In FIG. 4, the fastening member 105b is omitted. The mold apparatus 102 includes a first mounting plate 103, a second mounting plate 104, a fixed mold 105, a movable mold 106, and a pressure receiving material 107.

第１の取付板１０３は、固定盤１０１ａ（図１及び図２参照）に取り付けられる。第２の取付板１０４は、可動盤１０１ｂ（図１及び図２参照）に取り付けられる。第１の取付板１０３と第２の取付板１０４とは、互いに対向して配置される。   The first attachment plate 103 is attached to the fixed platen 101a (see FIGS. 1 and 2). The second attachment plate 104 is attached to the movable platen 101b (see FIGS. 1 and 2). The first mounting plate 103 and the second mounting plate 104 are disposed to face each other.

第１の取付板１０３には、締結部材１０５ｂによって、固定金型１０５が取り付けられる。第２の取付板１０４には、締結部材（図示せず）によって、可動金型１０６が取り付けられる。固定金型１０５に設けられる受圧面１０５ａと、可動金型１０６の受圧面１０６ａとは、互いに向かい合っている。受圧材１０７は、固定金型１０５の受圧面１０５ａの外周部分に設けられる。なお、受圧材１０７は、受圧面１０６ａの外周部分に設けられる場合もある。   A fixed mold 105 is attached to the first attachment plate 103 by a fastening member 105b. The movable mold 106 is attached to the second attachment plate 104 by a fastening member (not shown). The pressure receiving surface 105a provided on the fixed mold 105 and the pressure receiving surface 106a of the movable mold 106 face each other. The pressure receiving material 107 is provided on the outer peripheral portion of the pressure receiving surface 105 a of the fixed mold 105. The pressure receiving material 107 may be provided on the outer peripheral portion of the pressure receiving surface 106a.

図１ないし図４を参照する。第１の取付板１０３は、固定盤１０１ａに設けられたクランプ部材１０８ａにより、固定盤１０１ａに着脱自在に取り付けられる。第２の取付板１０４は、可動盤１０１ｂに設けられたクランプ部材１０８ｂにより、可動盤１０１ｂに着脱自在に取り付けられる。なお、固定盤１０１ａに対する第１の取付板１０３の取り付けや、可動盤１０１ｂに対する第２の取付板１０４の取り付けは、ボルト留め等で行われてもよい。   Please refer to FIG. 1 to FIG. The first mounting plate 103 is detachably attached to the fixed platen 101a by a clamp member 108a provided on the fixed platen 101a. The second mounting plate 104 is detachably attached to the movable platen 101b by a clamp member 108b provided on the movable platen 101b. Note that the attachment of the first attachment plate 103 to the fixed platen 101a and the attachment of the second attachment plate 104 to the movable platen 101b may be performed by bolting or the like.

油圧シリンダ１０１ｃは、可動盤１０１ｂを動かして可動盤１０１ｂを固定盤１０１ａに近づけ、固定金型１０５と可動金型１０６とを型締めする。このような型締めは、溶融樹脂の成形に必要な所定の圧力の下で行われる。   The hydraulic cylinder 101c moves the movable platen 101b to bring the movable platen 101b closer to the fixed platen 101a, and clamps the fixed mold 105 and the movable mold 106. Such mold clamping is performed under a predetermined pressure required for molding the molten resin.

このような油圧シリンダ１０１ｃの駆動により、第１の取付板１０３と第２の取付板１０４とが互いに近づき、受圧材１０７が、固定金型１０５の受圧面１０５ａと可動金型１０６の受圧面１０６ａとに挟まれる。これにより、固定金型１０５と可動金型１０６との間には、キャビティＣが形成される。キャビティＣは、パーティングライン面ＰＬにより密閉される。キャビティＣには、固定金型１０５や可動金型１０６に形成されたスプル（図示せず）を通して溶融樹脂が射出される。キャビティＣに充填された溶融樹脂は、成形されて成形品ＭＤとなる。   By such driving of the hydraulic cylinder 101 c, the first mounting plate 103 and the second mounting plate 104 come close to each other, and the pressure receiving material 107 is moved between the pressure receiving surface 105 a of the fixed mold 105 and the pressure receiving surface 106 a of the movable mold 106. Between. Thereby, a cavity C is formed between the fixed mold 105 and the movable mold 106. The cavity C is sealed by the parting line surface PL. Molten resin is injected into the cavity C through sprues (not shown) formed in the fixed mold 105 and the movable mold 106. The molten resin filled in the cavity C is molded into a molded product MD.

固定金型１０５とは反対側の第１の取付板１０３の外側面１０３ａには、複数の孔部１１０が設けられる。孔部１１０は、キャビティＣを形成する固定金型１０５の内周面１０５ｃから第１の取付板１０３に向けて延びる仮想垂線ＶＬ上に設けられる。その結果、第１の取付板１０３で並ぶ複数の孔部１１０は、成形品ＭＤの形状に似る。本実施の形態に関して詳細に述べると、孔部１１０は、外側面１０３ａの上側に四箇所横並びし、かつ、外側面１０３ａの下側に二箇所横並びして、成形品ＭＤの形状を覆う。なお、本実施の形態で示す孔部１１０の配置は、あくまで、一例にすぎない。   A plurality of holes 110 are provided on the outer surface 103 a of the first mounting plate 103 on the side opposite to the fixed mold 105. The hole 110 is provided on a virtual perpendicular VL extending from the inner peripheral surface 105 c of the fixed mold 105 forming the cavity C toward the first mounting plate 103. As a result, the plurality of holes 110 arranged on the first mounting plate 103 resemble the shape of the molded product MD. More specifically, the holes 110 are arranged in four places on the upper side of the outer surface 103a and in two places on the lower side of the outer surface 103a to cover the shape of the molded product MD. In addition, arrangement | positioning of the hole part 110 shown by this Embodiment is only an example to the last.

それぞれの孔部１１０には、プレート１１１が嵌め込まれる。プレート１１１は、鋼材で作られる。プレート１１１には、ボルト孔１１１ａが貫通している。また、それぞれの孔部１１０には、固定金型１０５に向かって延びる雌ネジ孔１１２が形成される。プレート１１１は、孔部１１０に嵌めこまれた後、ボルト１１３がボルト孔１１１ａと雌ネジ孔１１２とに螺合することにより、第１の取付板１０３に締付固定される。   A plate 111 is fitted into each hole 110. The plate 111 is made of steel. Bolt holes 111 a pass through the plate 111. Each hole 110 is formed with a female screw hole 112 extending toward the fixed mold 105. After the plate 111 is fitted into the hole 110, the bolt 113 is screwed into the bolt hole 111 a and the female screw hole 112, thereby being fastened and fixed to the first mounting plate 103.

ところで、固定金型１０５及び可動金型１０６を設計する際、射出成形時における型締め力と型内の樹脂圧力とに基づく予測撓み量が解析される。固定金型１０５及び可動金型１０６の予測撓み量の解析は、射出成形時における型締め力と型内の樹脂圧力とに基づいて行われる。この解析には、例えば、ＣＡＥ（Ｃｏｍｐｕｔｅｒ Ａｉｄｅｄ Ｅｎｇｉｎｅｅｒｉｎｇ）等が用いられる。この解析で、固定金型１０５や可動金型１０６の予測撓み量を低減するように、個々のプレート１１１の配置、大きさ、厚さ等が決定される。このようにプレート１１１を配置することで、固定金型１０５や可動金型１０６の部位ごとに適正な撓み量補正を行えるようになる。そして、この解析結果の精度が上昇し、トライアンドエラーを実施していた撓み調整も基本的に調整レスで行えるようになる。   By the way, when designing the fixed mold 105 and the movable mold 106, the predicted deflection amount based on the mold clamping force and the resin pressure in the mold at the time of injection molding is analyzed. Analysis of the predicted deflection amount of the fixed mold 105 and the movable mold 106 is performed based on the mold clamping force and the resin pressure in the mold at the time of injection molding. For this analysis, for example, CAE (Computer Aided Engineering) is used. In this analysis, the arrangement, size, thickness, and the like of each plate 111 are determined so as to reduce the predicted deflection amount of the fixed mold 105 and the movable mold 106. By arranging the plate 111 in this way, it becomes possible to correct the amount of deflection appropriately for each part of the fixed mold 105 and the movable mold 106. Then, the accuracy of the analysis result is improved, and the deflection adjustment that has been performed by trial and error can be basically performed without adjustment.

図５は、固定金型１０５の一部を拡大して示す側面断面図である。プレート１１１は、ボルト１１３によって第１の取付板１０３に取り付けられた際、距離ｄだけ第１の取付板１０３の外側面１０３ａから突出する。この距離ｄは、上記の解析結果により得られた、固定金型１０５の撓み量を最小にするような距離とする。   FIG. 5 is an enlarged side sectional view showing a part of the fixed mold 105. When the plate 111 is attached to the first attachment plate 103 by the bolt 113, the plate 111 protrudes from the outer surface 103a of the first attachment plate 103 by a distance d. This distance d is a distance obtained by the above analysis result so as to minimize the amount of bending of the fixed mold 105.

図１〜図５を参照する。このように構成された本実施の形態の射出成形装置１０１では、油圧シリンダ１０１ｃの駆動により可動盤１０１ｂが動き、固定金型１０５と可動金型１０６が開閉する。そして、キャビティＣに溶融樹脂が射出されることにより、成形品ＭＤの成形がなされる。   Please refer to FIG. In the injection molding apparatus 101 of the present embodiment configured as described above, the movable platen 101b moves by driving the hydraulic cylinder 101c, and the fixed mold 105 and the movable mold 106 open and close. Then, when the molten resin is injected into the cavity C, the molded product MD is molded.

本実施の形態の射出成形装置１０１では、成形時の撓み量の解析結果に基づいてプレート１１１が細分化されているので、そもそも固定金型１０５の調整は不要である。ここで、万が一、射出成形装置１０１の成形品ＭＤ（図２参照）の成形時にバリが生じて、固定金型１０５の調整が必要になった場合、作業者は、この成形品ＭＤを参照して、固定金型１０５におけるバリが生じたエラー箇所Ｖを特定し、エラー箇所Ｖでのバリの発生を防ぐよう、プレート１１１を部位ごとに個別に交換し、細かな厚み調整をすることもできる。   In the injection molding apparatus 101 of the present embodiment, since the plate 111 is subdivided based on the analysis result of the amount of bending at the time of molding, it is not necessary to adjust the fixed mold 105 in the first place. Here, in the unlikely event that burrs occur during the molding of the molded product MD (see FIG. 2) of the injection molding apparatus 101 and adjustment of the fixed mold 105 is necessary, the operator refers to this molded product MD. Thus, the error location V where the burr has occurred in the fixed mold 105 can be specified, and the plate 111 can be individually exchanged for each site and fine thickness adjustment can be performed so as to prevent the occurrence of burr at the error location V. .

本実施の形態では、固定金型１０５の撓み量を調整する際に、固定金型１０５を第１の取付板１０３から取り外す必要がない。そして、複数のプレート１１１が第１の取付板１０３の外側面１０３ａに細分化されて配置されており、固定金型１０５の撓み量を部位別に細かく調整できるようになっている。そのため、例えば、プレート１１１には、部位に応じた種類や厚み、材質の異なる鋼材を用いることができる。このように、本実施の形態の射出成形装置１０１では、射出成形時の金属の撓みによって発生するバリの抑制を簡単に行い、その効果を持続させることができる。   In the present embodiment, it is not necessary to remove the fixed mold 105 from the first mounting plate 103 when adjusting the amount of deflection of the fixed mold 105. A plurality of plates 111 are arranged on the outer surface 103a of the first mounting plate 103 so that the amount of bending of the fixed mold 105 can be finely adjusted for each part. Therefore, for example, steel plates having different types, thicknesses, and materials can be used for the plate 111. As described above, in the injection molding apparatus 101 of the present embodiment, it is possible to easily suppress the burrs generated by the bending of the metal during the injection molding, and to maintain the effect.

また、本実施の形態では、固定金型１０５の設計変更や固定金型１０５と第１の取付板１０３との接触箇所の調整は不要である。このため、成形品ＭＤの成形に最適な状態の固定金型１０５を容易かつ短時間で得ることができる。これは、金型製作のコストの低減や金型の納期の短縮、ひいては、成形品のコストの低減に繋がる。   Further, in the present embodiment, it is not necessary to change the design of the fixed mold 105 or adjust the contact portion between the fixed mold 105 and the first mounting plate 103. For this reason, it is possible to obtain the fixed mold 105 in an optimum state for molding the molded product MD easily and in a short time. This leads to a reduction in the cost of manufacturing the mold, a reduction in the delivery time of the mold, and a reduction in the cost of the molded product.
