[0001] 本発明は、ダイカスト铸造ゃ榭脂成型等に用いられる金型の冷却装置に関し、更 に詳しくは、金型に穿設された冷却穴内に冷却水のみ、或いは冷却水とエアーを圧 送することにより当該金型を冷却するようにした金型冷却装置に関するものである。 背景技術  TECHNICAL FIELD [0001] The present invention relates to a mold cooling device used for die-casting resin molding and the like, and more specifically, cooling water alone or cooling water and air is compressed in a cooling hole formed in the mold. The present invention relates to a mold cooling device that cools the mold by feeding. Background art
[0002] 本発明に近い技術として、特許第 3186027号公報に開示された金型冷却装置が ある。  As a technique close to the present invention, there is a mold cooling device disclosed in Japanese Patent No. 3186027.
この金型冷却装置は、冷却水及びエアーを圧送するための圧送部に、金型の冷却 穴内に冷却水を供給する冷却水供給径路と冷却穴内の冷却水をエアーパージする ための高圧エアーを送るエアーパージ径路とを接続せしめ、これら冷却水供給径路 とエアーパージ径路を合流させる流体合流部を備えてなり、該流体合流部を通して 金型の冷却穴内に冷却水とエアーを交互に圧送することにより金型の冷却穴の内部 に冷却水が残ることによる金型の冷やし過ぎを防止して金型温度をシビアに制御す ることができるものである（特許文献 1参照。；)。  In this mold cooling device, a cooling water supply path for supplying cooling water into the cooling holes of the mold and high-pressure air for air purging the cooling water in the cooling holes are supplied to a pumping section for pumping cooling water and air. Connected to the air purge path to be sent, and is provided with a fluid merging section that merges the cooling water supply path and the air purge path, and the cooling water and air are alternately pumped into the mold cooling hole through the fluid merging section. Thus, it is possible to control the mold temperature severely by preventing overcooling of the mold due to cooling water remaining inside the mold cooling hole (see Patent Document 1).
[0003] しかし、この金型冷却装置の場合、冷却水の圧送を行なう冷却水吐出ポンプを始 めとして電磁弁やタイマー等の機器類を略箱状に形成された筐体内に収容配設せし め、これらを制御回路で制御して冷却水の吐出量や吐出タイミング及びエアーパー ジのタイミング等をコントロールする仕組みになっているため、冷却水の吐出量や吐 出タイミングの異なる冷却系統が複数必要な場合には、冷却水及びエアーの圧送部 力 複数のホースによって流体を分岐し、筐体の内部に設置された複数の電磁弁に 接続していた。 However, in the case of this mold cooling apparatus, devices such as a solenoid valve and a timer are housed in a substantially box-shaped casing, starting with a cooling water discharge pump that pumps cooling water. Therefore, these systems are controlled by a control circuit to control the cooling water discharge rate, discharge timing, air purge timing, etc., so there are multiple cooling systems with different cooling water discharge rates and discharge timings. When necessary, the pumping force of cooling water and air was divided into fluids by multiple hoses and connected to multiple solenoid valves installed inside the housing.
従って、冷却系統を追加する場合には、冷却系統数の増加と共に増えたホースが 邪魔になり、新たな電磁弁の固定と新たな冷却水及びエアーの分岐をするために行 なう筐体内部での機器類等の組み込み作業が非常に繁雑であった。このことは、電 磁弁の故障や装置のメンテナンスを行なう場合においても同様であり、筐体内部のホ ースが邪魔をして作業を繁雑なものにして!/、た。 Therefore, when adding a cooling system, the hose increased with the increase in the number of cooling systems becomes a hindrance, and the inside of the housing that is used to fix a new solenoid valve and branch new cooling water and air The installation work of equipment etc. was very complicated. The same applies to the malfunction of the solenoid valve and the maintenance of the equipment. Seuss disturbed the work! /
[0004] また、この種の金型冷却装置では、金型の冷却穴に冷却水を圧送する冷却水吐出 ポンプとして、シリンダの内部がピストンで上下に仕切られたピストンポンプを使用し、 冷却水を吐出する水室がピストンの上側に配置され、ピストンを動作させるためのェ ァ一室がピストンの下側に配置されるように筐体の内部に設置していた (特許文献 2 参照)。  [0004] Further, in this type of mold cooling apparatus, a piston pump in which the inside of a cylinder is partitioned vertically by a piston is used as a cooling water discharge pump that pumps cooling water into a cooling hole of the mold. The water chamber that discharges water is disposed on the upper side of the piston, and the chamber for operating the piston is disposed on the lower side of the piston (see Patent Document 2).
一方、金型の冷却穴に供給される冷却水として、工業用水を循環して使用すること が多ぐすると冷却水中にごみが混入しやすくなり、そのためピストンが摺動する水室 におけるシリンダの内周面が傷つきやすぐ冷却水吐出ポンプの早期劣化を招いて いた。  On the other hand, if industrial water is circulated frequently as cooling water supplied to the cooling holes of the mold, dust tends to enter the cooling water, so that the inside of the cylinder in the water chamber where the piston slides The peripheral surface was damaged and the cooling water discharge pump was quickly deteriorated.

A fitting formed in the shape of a letter is hooked to the edge of the engagement hole, and the fixing joint is fixed to the branching mall holder to connect the connection joint to the distribution port of the branching mall holder. Since it is fixed so that it does not come off, there is no risk that the connection joint will fall off the branch connection port even if the internal pressure of the cooling system is high.
[0014] この際、図示実施例の如ぐ固定具の先端縁に突設した掛止爪を分岐マ二ホール ドの側壁部に係合掛止させるか、或 、は固定具を分岐マ二ホールドに係脱自在な掛 止ピンで固定することにより、固定具を分岐マ-ホールドに捻じ込み作業を伴うことな くワンタッチで簡便に着脱することが可能となると共に、捻じ込み作業を伴わないので ここでも筐体内部のコンパクトィ匕を図ることが可能となる。 At this time, as shown in the illustrated embodiment, a latching claw projecting from the tip edge of the fixture is engaged with the side wall of the branch manifold, or the fixture is connected to the branch manifold.

Since the discharge water chamber is located on the lower side of the piston, in the water chamber of the cooling water discharge pump, waste that has a higher specific gravity than water naturally sinks to the opposite side of the lower surface of the piston and has a higher specific gravity than water. As a result, even if the piston slides along the inner wall of the cylinder, the piston and the inner surface of the cylinder are less likely to be damaged by dust. In addition, early deterioration of the cooling water discharge pump can be prevented.

Branch distribution 4 distribution connection 4 &, 41) ', 411 is connected and connected.
接続継手 18a,18b,"',18nに分岐配管ユニット 5a,51v ",5nないし封止キャップ 10a ,10bを螺合接続させる際に、接続継手 18a,181v',18nの取付け摘み 13に工具を係 合させる。  When connecting the branch piping units 5a, 51v ", 5n or the sealing caps 10a, 10b to the connection joints 18a, 18b," ', 18n, a tool is attached to the mounting knob 13 of the connection joints 18a, 181v', 18n. Engage.
[0026] この様に、接続継手 18a,18b,"',18nは分岐マ-ホールド 4の分配接続口 4a,4b,"', 4nに挿し込み接続されているだけなので、冷却水やエアーに内圧が力かった場合 でも接続継手 18a, 18b,…， 18ηが分岐マ-ホールド 4の分配接続口 4a,41v ",4nから 脱落しな 、ように固定具 28で固定することが望ま 、。  [0026] In this way, the connection joints 18a, 18b, "', 18n are only inserted and connected to the distribution connection ports 4a, 4b,"', 4n of the branch mall 4, so that they can be connected to cooling water and air. It is desirable to fix the joints 18a, 18b, ..., 18η with the fixture 28 so that the joints 18a, 18b, ..., 18η do not fall off the branch connection 4a, 41v ", 4n even when the internal pressure is high.
[0027] 固定具 28は、鉄やアルミ等の金属材カもなる細帯板を用いて、図 4 (a)に示した実 施例のごとぐ分岐マ二ホールド 4を長手方向と直交する方向に跨ぐ大きさに略コの 字形に形成すると共に、接続継手 18a,181v',18nと対応する位置に、取付け摘み 13 の外径より少し小径で接続ネジ部 12の外径より少し大径の係合穴 29を開口形成し てなり、分岐マ-ホールド 4に適当な手段でもって着脱自在に固定される。 なお、図 4 (b)に示した実施例は、係合穴 29に連通する切り割 29 'を形成したもの である。 [0027] The fixing tool 28 uses a narrow strip made of a metal material such as iron or aluminum, and the branch manifold 4 as shown in Fig. 4 (a) is perpendicular to the longitudinal direction. It is formed in an approximately U shape so as to extend across the direction, and is slightly smaller than the outer diameter of the mounting knob 13 and slightly larger than the outer diameter of the connecting screw portion 12 at a position corresponding to the connecting joint 18a, 181v ', 18n. The engagement hole 29 is formed so as to be detachably fixed to the branch mall holder 4 by an appropriate means. In the embodiment shown in FIG. 4B, a slit 29 ′ communicating with the engagement hole 29 is formed.
[0028] 而して、接続継手 18a,181v", 18ηの接続ネジ部 12に固定具 28の係合穴 29を貫揷 させて係合穴 29の口縁に取付け摘み 13を係合掛止せしめ、その状態で固定具 28 を分岐マ-ホールド 4に着脱自在に固定することにより、当該接続継手 18a,181v , 18ηを分岐マ-ホールド 4の分配接続口 4a,41v",4nに対して冷却水やエアーに内 圧が力かった場合でも抜け落ちな 、ように固定させるものである。  [0028] Thus, the engagement hole 29 of the fixture 28 is passed through the connection thread portion 12 of the connection joint 18a, 181v ", 18η, and the attachment knob 13 is engaged and latched on the lip of the engagement hole 29. In this state, the fixture 28 is detachably fixed to the branch mall holder 4 so that the connection joints 18a, 181v, 18η are connected to the distribution connection ports 4a, 41v ", 4n of the branch mall holder 4. It is fixed so that it does not fall out even when the internal pressure is strong against cooling water or air.
この場合、固定具 28を分岐マ-ホールド 4に固着する前に、各接続継手 18a,18b, ••·, 18ηに分岐配管ユニット 5&,51ν· ·,5η及び封止キャップ 10a,10bを接続しておくこと が好ましい。  In this case, before fixing the fixture 28 to the branch mall 4, connect the branch piping units 5 &, 51ν ·, 5η and the sealing caps 10a, 10b to the connecting joints 18a, 18b, ••, 18η. It is preferable to keep it.
[0029] なお、図 4 (b)に示すごとぐ係合穴 29に連通する切り割 29 'を形成した場合には、 接続継手 18a,18b," ',18nに分岐配管ユニット 5a,51v",5n及び封止キャップ 10a, 10 bを接続して、接続継手 18a, 18b," ·, 18ηを分岐マ-ホールド 4の分配接続口 4a,4b, … ,4ηに挿し込み接続せしめた後でも、切り割 29 'を通して係合穴 29の口縁を取付 け摘み 13に係合掛止させることが可能なので、最後に固定具 28を分岐マ-ホール ド 4に取り付けるようにしても良 、。  [0029] As shown in Fig. 4 (b), when the cut 29 'communicating with the engagement hole 29 is formed, the connecting joints 18a, 18b, "', 18n are connected to the branch piping unit 5a, 51v". , 5n and sealing caps 10a, 10b are connected, and after connecting joints 18a, 18b, "..., 18η are inserted into branch connection 4 distribution connection ports 4a, 4b, ..., 4η Since the lip of the engagement hole 29 can be attached and latched to the knob 13 through the slit 29 ′, the fixture 28 can be attached to the branch manifold 4 at the end.
[0030] 固定具 28を分岐マ-ホールド 4に着脱自在に固定する手段としては!、ろ 、ろ考え られるが、捻じ込み等の操作を必要とすることがなくワンタッチで着脱し得ると同時に 不用意に脱落することなく着脱し得る構造を採択するのが好ましい。  [0030] As a means of detachably fixing the fixing tool 28 to the branch holder 4, it can be considered, but it can be attached and detached with one touch without requiring an operation such as screwing. It is preferable to adopt a structure that can be attached and detached without falling off.
具体的には、図 5 (a)に示した実施例のものは、略コの字形に形成した固定具 28の 水平部 28aの先端縁に内側に向けて掛止爪 28bを突設せしめ、その掛止爪 28bを分 岐マ-ホールド 4の側壁部に凹設した係合段部 43に係脱自在に係合掛止させること により、固定具 28を分岐マ-ホールド 4に捻じ込み等の操作を必要とすることなくワン タツチで着脱し得るように構成したものである。  Specifically, in the embodiment shown in FIG. 5 (a), a hooking claw 28b is projected inwardly toward the tip edge of the horizontal portion 28a of the fixture 28 formed in a substantially U shape, By engaging and latching the latching claw 28b with the engaging step 43 provided in the side wall of the branch marker holder 4 so as to be freely disengaged, the fixing tool 28 is screwed into the branch marker holder 4, etc. It is configured so that it can be attached and detached with one touch without the need for this operation.

Fixed by inserting freely The tool 28 is configured to be detachable without requiring an operation such as screwing it into the branch mall holder 4.
[0032] 固定具 28は、分岐マ-ホールド 4に装着された複数個の接続継手 18a,181v", 18η を同時に固定できるように形成しても良いが、分岐配管ユニット 5a,51v", 5ηの一部 追加や削除が必要な場合を考慮すると、 1つ 1つの接続継手 18&,181ν··,18η毎に独 立させて設けることが好ま 、。  [0032] The fixture 28 may be formed so that a plurality of connection joints 18a, 181v ", 18η attached to the branch manifold 4 can be fixed simultaneously, but the branch pipe units 5a, 51v", 5η In consideration of the case where addition or deletion of a part is necessary, it is preferable to provide each connection joint 18 &, 181ν ··, 18η independently.
[0033] 更に、この固定具 28は、分岐マ-ホールド 4に装着された全ての接続継手 18a,18b ，…， 18ηに対して適用しても良いし、図示実施例のように封止キャップ 10a, 10bを接続 する接続継手 18ηに対してのみに適用し、分岐配管ユニット 5a,5b,"',5nを接続する 接続継手 18a,18b,…は、分岐配管ユニット 5a,5b,"',5nを介して筐体 Aに取り付ける ことにより分岐マ-ホールド 4の分配接続口 4&,41ν··,4ηから抜け出な 、ようにしても 良い。  [0033] Further, the fixture 28 may be applied to all the connection joints 18a, 18b, ..., 18η mounted on the branch mall holder 4, or a sealing cap as shown in the illustrated embodiment. Applicable only to connecting joint 18η connecting 10a, 10b, connecting pipe 18a, 18b, ... connecting branch piping unit 5a, 5b, "', 5n is connected to branch piping unit 5a, 5b,"', By attaching to the housing A via 5n, it may be possible not to escape from the distribution connection ports 4 &, 41ν,.
[0034] 分岐配管ユニット 5a,5b,"',5nを筐体 Aに取り付ける場合、外部ホース (冷却水供 給ホース 16a,161v",16nやエアー供給ホース 17a,17b,"',17n)を接続させるソケット 14a, 14b," ·, 14ηを介して筐体 Aに固定する。すなわち、ソケット 14a,14b,"',14nの外 周に取付け板 31を一体に固着しておき、その取付け板 31を筐体 Aに開口形成され た設置穴 32の口縁にあてがいビスなどで固定するものである。  [0034] When installing branch piping units 5a, 5b, "', 5n to case A, connect external hoses (cooling water supply hoses 16a, 161v", 16n and air supply hoses 17a, 17b, "', 17n) Fix it to case A via sockets 14a, 14b, "·, 14η to be connected. That is, the mounting plate 31 is fixed to the outer periphery of the sockets 14a, 14b, "', 14n integrally, and the mounting plate 31 is attached to the edge of the installation hole 32 formed in the housing A with a screw or the like. It is to be fixed.
ちなみに、分岐配管ユニット 5a,51v",5nがない封止キャップ 10a,10bと対応する部 分の設置穴 26は閉塞板 33で塞がれて ヽる。  Incidentally, the installation holes 26 corresponding to the sealing caps 10a, 10b without the branch piping units 5a, 51v ", 5n are closed by the closing plate 33.
[0035] また、金型の冷却穴に冷却水及びエアーを圧送するタイプの金型冷却装置の場合 には、図 6に示す如ぐ接続継手 18ηに分岐配管ユニット 5n,8nを螺合接続したもの を複数個（例えば、冷却水用とエアー用に各 1個で合計 2個）を並列に配設して 1組 の分岐ユニットを形成せしめ、その分岐ユニットにおける接続継手 18ηのいずれかを 冷却水用分岐マ-ホールド 4の分配接続口 4ηに抜き差し可能に挿し込み接続すると 共に、残りの接続継手をエアー用分岐マ-ホールド 7の分配接続口 7ηにそれぞれ抜 き差し可能に挿し込み接続するように構成しても良 、。  [0035] In the case of a mold cooling device of a type in which cooling water and air are pumped into the cooling holes of the mold, branch piping units 5n and 8n are screwed and connected to a connection joint 18η as shown in FIG. Plural items (for example, one each for cooling water and one for cooling water) are arranged in parallel to form one set of branch units, and one of the connecting joints 18η in that branch unit is cooled. Insert and connect to the distribution connection port 4η of the branch branch for water 4 so that it can be inserted and removed, and connect the remaining connection joints to the distribution connection port 7η of the branch port for air 7 so that they can be inserted and removed. It may be configured as follows.
[0036] 次に、冷却水を金型の冷却穴に圧送する冷却水吐出ポンプ 2について説明する。  Next, the cooling water discharge pump 2 that pumps the cooling water into the cooling holes of the mold will be described.
本発明に用いられる冷却水吐出ポンプ 2としては、通常用いられる周知のポンプを 使用することができる力 シリンダの内部がピストンで仕切られ、高圧エアーで動作す るピストンポンプを使用することが好まし 、。 As the cooling water discharge pump 2 used in the present invention, a well-known pump that is usually used is used. Force that can be used It is preferable to use a piston pump in which the inside of the cylinder is partitioned by a piston and operates with high-pressure air.
[0037] すなわち、図 7に模式的に示したシリンダポンプは、同軸状に連結配置された 2個 のシリンダ 34a,34b内に 1本のピストンロッド 35で連結されたピストン 36a,36bをそれぞ れ摺動自在に設置し、一方のシリンダ 34aのヘッド側を冷却水を溜めておくための水 室 2aとし、それ以外のシリンダ室内を全てエアー室 2bとなし、エアー室 2bに供給す る高圧エアーの作用により水室 2a内の冷却水を高い吐出圧力でもって圧送できると 同時に、格別に冷却装置を介在設置せずとも常温の水を冷却することが出来るよう に構成したものである。なお、図中の符号 37は冷却水の給排口であり、符号 38はェ ァ一の給排ロを示す。  That is, the cylinder pump schematically shown in FIG. 7 has pistons 36a and 36b connected by a single piston rod 35 in two cylinders 34a and 34b that are coaxially connected. It is installed slidably, and the head side of one cylinder 34a is used as a water chamber 2a for storing cooling water. The other cylinder chambers are all formed as air chambers 2b, and the high pressure is supplied to the air chamber 2b. The cooling water in the water chamber 2a can be pumped with a high discharge pressure by the action of air, and at the same time, the water at room temperature can be cooled without specially installing a cooling device. In the figure, reference numeral 37 denotes a cooling water supply / discharge port, and reference numeral 38 denotes an air supply / discharge port.
従って、このシリンダポンプを使用すれば、冷却水を吐出供給する必要がないとき には冷却水の吐出動作を停止させておくことが可能となり、その分当該ポンプ及び冷 却水用電磁弁に掛カる負担並びにランニングコストを軽減させることが出来るもので ある (詳細は、特許第 3419574号公報参照)。  Therefore, if this cylinder pump is used, it becomes possible to stop the cooling water discharge operation when it is not necessary to discharge and supply the cooling water, and accordingly, the pump and the cooling water solenoid valve are suspended. This can reduce the burden of running and running costs (see Japanese Patent No. 3419574 for details).
[0038] 本発明では、このピストンポンプを 1台又は複数台使用し、その全てのピストンポン プ（冷却水吐出ポンプ 2)が、図面に示す如ぐエアー室 2bが天側に位置し冷却水を 吐出する水室 2aが地側に位置するように、ピストン 36aの下側になるように配置されて いる。  [0038] In the present invention, one or a plurality of piston pumps are used, and all of the piston pumps (cooling water discharge pumps 2) have an air chamber 2b on the top side as shown in the drawing, and the cooling water. The water chamber 2a that discharges water is disposed below the piston 36a so that it is located on the ground side.
[0039] 従って、冷却水吐出ポンプ 1の水室 2a内部において、冷却水に混入した水より比 重の重 、ごみ (微細な小石等）は水中で自然に沈んでフランジ 39上面に溜まるように なる。その結果、水より比重の重いごみ (微細な小石等）がピストン 36aとシリンダ 34a の内周面との間に入り込むことがほとんどなくなる。  [0039] Therefore, in the water chamber 2a of the cooling water discharge pump 1, the specific gravity and dust (fine pebbles, etc.) of the specific gravity of the water mixed in the cooling water sinks naturally in the water and accumulates on the upper surface of the flange 39. Become. As a result, dust (such as fine pebbles) having a higher specific gravity than water hardly enters between the piston 36a and the inner peripheral surface of the cylinder 34a.
