Description

本発明は、ダイカスト鋳造や樹脂成型等に用いられる金型を冷却するための方法及び装置に関し、特に、金型に穿設された冷却穴内に冷却水と高圧エアを交互に供給することにより金型を冷却するようにした金型の冷却方法及び冷却装置に関し、更に詳しくは、前記冷却水及び高圧エアが流通する冷却水通路の目詰まり具合を検知することが可能な金型の冷却方法及び冷却装置に関するものである。   The present invention relates to a method and an apparatus for cooling a mold used for die casting, resin molding, and the like, and in particular, by supplying cooling water and high-pressure air alternately into cooling holes formed in the mold. More specifically, a mold cooling method and a cooling device for cooling a mold, and more specifically, a mold cooling method capable of detecting the clogging of a cooling water passage through which the cooling water and high-pressure air flow, and The present invention relates to a cooling device.

ダイカスト鋳造や樹脂成型等に用いられる金型を冷却する方法として、従来から、金型にφ２.５mm〜φ５.０mmの細い冷却穴を多数個開穿し、各冷却穴にそれぞれ金型冷却パイプを装着せしめ、冷却パイプを通して高圧の冷却水を一定時間通水した後に、金型の冷却穴内に残った冷却水を高圧エアで除去するいわゆる間欠通水冷却方法が行なわれている（例えば、特許文献１参照。）。
この金型冷却方法では、冷却水及び高圧エアが流通する冷却パイプ並びに冷却穴の内部（冷却水通路）が狭いので冷却水に含まれるごみや水垢（スケール）等の不純物が詰まりやすいため、予め目詰まりしないような対策を施すだけでなく、目詰まりを早期に検出できるようにすることが望まれていた。 Conventionally, as a method of cooling a die used for die casting or resin molding, a number of thin cooling holes of φ2.5 mm to φ5.0 mm have been drilled in the die, and a mold cooling pipe is provided in each cooling hole. A so-called intermittent water cooling method is performed in which high pressure cooling water is passed through a cooling pipe for a certain period of time and then the cooling water remaining in the mold cooling holes is removed with high pressure air (for example, patents). Reference 1).
In this mold cooling method, since the cooling pipe through which cooling water and high-pressure air flow and the inside of the cooling hole (cooling water passage) are narrow, impurities such as dust and scale (scale) contained in the cooling water are likely to be clogged in advance. In addition to taking measures to prevent clogging, it has been desired to be able to detect clogging early.

冷却水及び高圧エアが流通する冷却パイプ並びに冷却穴の内部（以下、冷却水通路と称する。）の目詰まりを検知する方策として、冷却水通路に流量センサを設置して冷却水通路内を流れる冷却水の流量の変化を監視する方法が考えられる。すなわち、冷却水通路がごみや水垢等の不純物で目詰まりをすると、それに伴って冷却水通路内を流れる冷却水の流量が減少するので、冷却水の流量変化を監視することにより冷却水通路の目詰まりを検知できると考えるものである。
しかし、流量センサは一般的に高圧の冷却水と高圧エアを交互に流通させるような環境下では故障しやすく、しかもその外形が比較的大きく且つ高価であることから、金型に多数個形成されている各冷却穴に適用することはコスト的にも不適当である。 As a measure for detecting clogging in the cooling pipe through which cooling water and high-pressure air circulate and the inside of the cooling hole (hereinafter referred to as cooling water passage), a flow sensor is installed in the cooling water passage to flow through the cooling water passage. A method for monitoring the change in the flow rate of the cooling water can be considered. That is, if the cooling water passage is clogged with impurities such as dust and scale, the flow rate of the cooling water flowing through the cooling water passage is reduced accordingly. It is thought that clogging can be detected.
However, in general, flow sensors are likely to fail in an environment in which high-pressure cooling water and high-pressure air are alternately circulated, and the outer shape thereof is relatively large and expensive. It is inappropriate to apply to each cooling hole.

本発明に係る金型の冷却方法及び冷却装置によれば、一般的に高価でしかも故障しやすい流量センサを使用せずとも堅牢で安価なフロースイッチを使用して、冷却水及び高圧エアが流通する金型の冷却穴を含む冷却水通路を流れる冷却水の通過時間を計測することにより、冷却水通路の目詰まり具合を簡便に検知することが出来る。
よって、金型の冷却穴を含む冷却水通路の目詰まり具合が許容範囲を超える前に冷却水通路に詰まっている異物や水垢を除去したり、或いは冷却水通路を構成する冷却パイプ及び金型部品(中子ピン等)を交換するなど所要のメンテナンスを施すことが可能となる。その結果、金型温度を設定温度に維持しながら金型を常に適性に冷却することが出来るようになる。 According to the mold cooling method and cooling apparatus of the present invention, cooling water and high-pressure air are circulated using a robust and inexpensive flow switch without using a flow sensor that is generally expensive and prone to failure.

Therefore, before the clogging condition of the cooling water passage including the cooling hole of the mold exceeds the allowable range, the foreign matter and scale clogged in the cooling water passage are removed, or the cooling pipe and the die constituting the cooling water passage. Necessary maintenance such as replacement of parts (core pins, etc.) can be performed. As a result, the mold can always be appropriately cooled while maintaining the mold temperature at the set temperature.

以下、本発明の具体的な好適実施例を図面を参照しながら詳細に説明するが、本発明は図示実施例のものに限定されるものではない。   Hereinafter, specific preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the illustrated embodiments.

図１は，本発明に係る金型の冷却方法及び冷却装置を金型Ａに適用した状態の実施の一例を説明する模式図であり、金型Ａには冷却を必要とする所要の個所にその背面側からキャビティ側へ向けてφ２.５mm〜φ５.０mm程度の細い冷却穴１が多数個開穿され、そして各冷却穴１にはそれぞれ金型冷却パイプ２が着脱取外し可能に装着され、冷却パイプ２を通して金型冷却穴１内に冷却水と高圧エアを交互に流すことによって金型Ａを冷却する間欠通水冷却が行なわれる仕組みになっている。   FIG. 1 is a schematic diagram for explaining an example of a state in which a mold cooling method and a cooling apparatus according to the present invention are applied to a mold A, and the mold A has a required portion that requires cooling. A large number of thin cooling holes 1 of about φ2.5 mm to φ5.0 mm are opened from the back side to the cavity side, and a mold cooling pipe 2 is detachably attached to each cooling hole 1. Intermittent water cooling for cooling the mold A is performed by alternately flowing cooling water and high-pressure air into the mold cooling hole 1 through the cooling pipe 2.

従って、各冷却パイプ２並びに冷却穴１の内部すなわち冷却水通路には、冷却水及び高圧エアが交互に流通することになる。
なお、図中の符号Ｂは、冷却水供給源に接続された冷却水配管３から供給される冷却水とエア供給源に接続されたエア配管４から供給されるエアを各冷却パイプ２に分配するための金型冷却用マニホールドであり、冷却パイプ２は入側ホース２６及び出側ホース２７を介してこの冷却用マニホールドＢに連通接続される。 Accordingly, the cooling water and the high-pressure air alternately flow through the cooling pipes 2 and the cooling holes 1, that is, the cooling water passages.
In addition, the code | symbol B in a figure distributes the cooling water supplied from the cooling water piping 3 connected to the cooling water supply source, and the air supplied from the air piping 4 connected to the air supply source to each cooling pipe 2. The cooling pipe 2 is connected to the cooling manifold B through an inlet hose 26 and an outlet hose 27.

ちなみに、金型Ａの冷却穴１及び冷却パイプ２には、冷却水が入口側から出口側へ一方通行に流れるタイプと、図示例のごとく冷却穴１がキャビティ側へ向けて貫通せずに開穿され、その冷却穴１に内パイプ２１と外パイプ２２及びヘッド部２３とで冷却水の往路と復路を形成した２重パイプ構造の往復式タイプがあり、往復式タイプの冷却パイプでは、ヘッド部２３に形成されたホース接続口の一方を入口側（のホース接続口）２４とし他方を出口側（のホース接続口）２５としている。   Incidentally, in the cooling hole 1 and cooling pipe 2 of the mold A, the cooling water flows in one direction from the inlet side to the outlet side, and the cooling hole 1 is opened without penetrating toward the cavity side as shown in the illustrated example. There is a reciprocating type of double pipe structure in which a cooling water forward path and a return path are formed by an inner pipe 21, an outer pipe 22 and a head portion 23 in the cooling hole 1. In the reciprocating type cooling pipe, One of the hose connection ports formed in the portion 23 is the inlet side (the hose connection port) 24 and the other is the outlet side (the hose connection port) 25.

そして本発明の第１発明では、図２に示すごとく、金型の冷却穴１を通過した冷却水の出口側に設置されるフロースイッチ５と、冷却穴１に対する冷却水の通水開始から上記フロースイッチ５が通水を検知するまでの時間を計測するタイマー６と、タイマー６で得られた計測値を以前計測したデータと比較する比較部８とを備えて構成され、冷却パイプ２の入側ホース２１を通して金型の冷却穴１に供給される冷却水の通水開始からフロースイッチ５が通水を検知するまでの時間を計測して、得られた計測値をそれより以前に計測したデータと比較することにより、冷却水及び高圧エアが流通する冷却水通路の目詰まり具合を検知するものである。   And in 1st invention of this invention, as shown in FIG. 2, the flow switch 5 installed in the exit side of the cooling water which passed the cooling hole 1 of the metal mold | die, and the above-mentioned from the start of water flow of the cooling water to the cooling hole 1 A timer 6 that measures the time until the flow switch 5 detects water flow, and a comparison unit 8 that compares the measured value obtained by the timer 6 with the previously measured data are provided. The time from the start of the flow of the cooling water supplied to the mold cooling hole 1 through the side hose 21 until the flow switch 5 detects the flow of water was measured, and the measured value obtained before that was measured By comparing with the data, the degree of clogging of the cooling water passage through which the cooling water and high-pressure air flow is detected.

すなわち、金型の冷却穴１に冷却水と高圧エアを交互に流す際に、冷却水の通水開始をスタート信号とし、冷却水が冷却パイプ２の入口側２４から金型の冷却穴１を通って冷却穴１の出口側、すなわち冷却パイプ２の出口側２５に設けたフロースイッチ５が通水を検知した時の通水検知信号をストップ信号として、冷却水の通水開始からフロースイッチ５が通水を検知するまでの時間をタイマー６で計測し、ここで得られた計測値をメモリ７に蓄えられた以前に計測したデータと比較部８で比較し、今回得られた計測値が以前に計測した値（データ）より長くなった場合に目詰まりがあると判定し、冷却水及び高圧エアが流通する冷却水通路の目詰まり具合を検知するものである。
従って、フロースイッチ５は検知できる最低の流量に調節しておき、今回得られた計測値と以前計測して得られた値（データ）との差が次第に長くなる場合には冷却水通路に水垢（スケール）が徐々に成長し目詰まりが進行していると判定され、得られた計測値が無限大であった（フロースイッチが通水を検知しなかった）場合には冷却水通路が完全に目詰まりしていると判定される。 That is, when cooling water and high-pressure air are alternately flown into the mold cooling hole 1, the start of cooling water flow is used as a start signal, and the cooling water enters the mold cooling hole 1 from the inlet side 24 of the cooling pipe 2. The flow switch 5 from the start of cooling water flow using the water flow detection signal when the flow switch 5 provided on the outlet side of the cooling hole 1, that is, the outlet side 25 of the cooling pipe 2 detects water flow, as a stop signal. The time until the water is detected by the timer 6 is measured by the timer 6, the measured value obtained here is compared with the previously measured data stored in the memory 7 by the comparison unit 8, and the measured value obtained this time is When it becomes longer than the value (data) measured before, it determines with clogging, and detects the clogging state of the cooling water channel through which cooling water and high pressure air circulate.
Therefore, the flow switch 5 is adjusted to the lowest flow rate that can be detected, and when the difference between the measured value obtained this time and the value (data) obtained by the previous measurement becomes longer gradually, (Scale) grows gradually and it is judged that clogging is progressing, and when the measured value obtained is infinite (the flow switch did not detect water flow), the cooling water passage is complete Is determined to be clogged.

今回得られた計測値を以前計測して得られたデータと比較部８で比較する場合に、冷却水の通水毎にその時に得られた計測値をメモリ７に記憶させて、例えば１回前又は１０回前に計測して得られた計測値と比較するようにしても良いし、或いは予め設定された数値（データ）をメモリ７に記憶させておきその設定値と比較するようにしても良い。   When the measurement value obtained this time is compared with the data obtained by the previous measurement by the comparison unit 8, the measurement value obtained at that time is stored in the memory 7 for each flow of the cooling water, for example, once. You may make it compare with the measured value obtained by measuring before or 10 times before, or memorize the preset numerical value (data) in the memory 7 and compare it with the set value. Also good.

本発明で使用されるフロースイッチ５としては、市販されている通常のフロースイッチを使用することができるが、鋳造金型の周辺に設置する関係上できるだけ小型で堅牢なケース等に収容しえるものが望ましい。具体的には、フロースイッチ本体の内部を流れる冷却水の流量変化によって動作するフラッパーがあり、冷却水の流量が設定値より増加または減少するとフラッパーの動作によりスイッチがオンして、電気信号（通水検知信号）を発信するタイプのものが好適に用いられる。   As the flow switch 5 used in the present invention, a commercially available normal flow switch can be used, but it can be housed in a case that is as small and robust as possible because it is installed around the casting mold. Is desirable. Specifically, there is a flapper that operates by changing the flow rate of the cooling water flowing inside the flow switch body. When the flow rate of the cooling water increases or decreases from the set value, the switch is turned on by the operation of the flapper and an electrical signal ( A type that transmits a water detection signal) is preferably used.

また、本発明の第２発明では、図３に示すごとく、金型冷却穴１に冷却水が入る入口側及び冷却穴１を通過した冷却水の出口側に設置されるフロースイッチ５ａ,５ｂと、上記入口側に設置したフロースイッチ５ａが通水を検知してから上記出口側に設置したフロースイッチ５ｂが通水を検知するまでの時間を計測するタイマー６と、タイマー６で得られた計測値を以前計測したデータと比較する比較部８とを備えて構成され、入側ホース２６から冷却パイプ２の入口側２４を通して金型の冷却穴１に供給される冷却水により上記入口側に設置したフロースイッチ５ａが通水を検知してから冷却穴１の出口側、すなわち冷却パイプ２の出口側２５に設置したフロースイッチ５ｂが通水を検知するまでの時間を計測して、得られた計測値をそれより以前に計測して得られたデータと比較することにより、冷却水及び高圧エアが流通する冷却水通路の目詰まり具合を検知するようにしたものである。
この第２発明の場合も、冷却水通路の目詰まり具合を検知する原理は第１発明と同様なので詳細な説明は省略する。 In the second invention of the present invention, as shown in FIG. 3, flow switches 5a and 5b installed on the inlet side where the cooling water enters the mold cooling hole 1 and on the outlet side of the cooling water passing through the cooling hole 1, The timer 6 for measuring the time from when the flow switch 5a installed on the inlet side detects water flow until the flow switch 5b installed on the outlet side detects water flow, and the measurement obtained by the timer 6 Comparing unit 8 for comparing values with previously measured data, it is installed on the inlet side by cooling water supplied from inlet hose 26 through inlet side 24 of cooling pipe 2 to mold cooling hole 1. It was obtained by measuring the time from when the flow switch 5a detected water flow until the flow switch 5b installed on the outlet side of the cooling hole 1, that is, the outlet side 25 of the cooling pipe 2, detects water flow. Measured value The clogging degree of the cooling water passage through which the cooling water and the high-pressure air circulate is detected by comparing with the data obtained by measuring before.
Also in the case of the second invention, the principle for detecting the clogging condition of the cooling water passage is the same as that of the first invention, so that the detailed explanation is omitted.
