【発明の詳細な説明】
産業上の利用分野
本発明は、射出成形、射出圧縮成形に用いる冷却手段を
具備した樹脂成形用金型に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mold for resin molding equipped with cooling means used in injection molding and injection compression molding.
従来の技術
従来、金型を加熱する手段として金型の成形部近傍に誘
導加熱コイルや電気ヒーターを設けることにより加熱す
る方法があり、金型の成形部表面近傍に設けられた温調
媒体流路に水または混油を流して金型を冷却するという
手段を取っていた。Conventional technology Conventionally, there has been a method of heating a mold by installing an induction heating coil or an electric heater near the molding part of the mold. The method used was to cool the mold by running water or mixed oil through the channel.
発明が解決しようとする課題
しかしながら上記のような構成では、冷却の際、小さな
金型を用いたときに細い流路になると水や油では流れに
くく、高圧力のポンプが必要となってくる。Problems to be Solved by the Invention However, with the above configuration, when a small mold is used during cooling, the narrow flow path makes it difficult for water or oil to flow, necessitating a high-pressure pump.
本発明は上記問題点に鑑み、金型が小さいために冷却媒
体流路が細い流路となる場合、媒体を液化炭酸ガスある
いはエアーにすることにより流路内を流れやすくし、金
型を容易に冷却することができる樹脂成形用金型を提供
するものである。In view of the above-mentioned problems, the present invention has been developed in the case where the mold is small and the coolant flow path is narrow, by using liquefied carbon dioxide or air as the medium to facilitate the flow in the flow path, making it easier to replace the mold. The present invention provides a mold for resin molding that can be cooled to a maximum temperature.
課題を解決するための手段
上記課題を解決するために本発明の樹脂成形用金型は、
金型の成形部表面近傍に液化炭酸ガスあるいはエアーの
冷却媒体流路を設けたものである。Means for Solving the Problems In order to solve the above problems, the resin molding mold of the present invention has the following features:
A cooling medium flow path for liquefied carbon dioxide or air is provided near the surface of the molding part of the mold.
作用
本発明は上記した構成によって、細い流路内でも媒体が
スムーズに流れ、金型の冷却が容易にできることになる
。Effect of the present invention With the above-described configuration, the medium can flow smoothly even in a narrow channel, and the mold can be easily cooled.
実施例
以下本発明の一実施例の樹脂成形用金型について、図面
を参照しながら説明する。EXAMPLE Hereinafter, a mold for resin molding according to an example of the present invention will be explained with reference to the drawings.

体流路である。The drawing shows a cross section of the main part of a resin molding die in an embodiment of the present invention. In the figure, l is a fixed side mounting plate, 2 is a fixed side template, 3 is a movable side template, 4 is a movable side receiving plate,
5 is a stationary insert, 6 is a movable insert, 7 is a cavity, 8 is a sprue, 9 is an ejector turbine, and 10 is a coolant flow path.

流路内でも流れやすくなる。The fixed side template 2 is fixed to the temporary 1 at the fixed side attachment, and the movable side template 3 is fixed to the movable side receiving plate 4. A stationary insert 5 is attached to the fixed template 2, and a movable insert 6 is attached to the movable template 3. A cavity 7 is formed between the nests 5 and 6, and the resin is filled into the cavity 7 through the sprue 8. A mold heated by an induction heating coil or an electric heater is cooled by flowing liquefied carbon dioxide gas or air through the cooling medium channel 11. Since liquefied carbon dioxide gas becomes a gas when flowing through a channel, it flows more easily even in a narrow channel than liquids such as water or oil.
発明の効果
以上のように本発明は金型の成形部表面近傍に冷却媒体
流路を設け、この流路に流す媒体を液化炭酸ガスあるい
はエアーにすることにより細い流路内でも媒体が流れや
すくなり、金型を容易に冷却することができる。Effects of the Invention As described above, the present invention provides a cooling medium flow path near the surface of the molding part of the mold, and by using liquefied carbon dioxide or air as the medium to flow through this flow path, the medium can flow easily even in a narrow flow path. This allows the mold to be easily cooled.
