ドピン５及びガイド溝６の耐摩耗性の向上を図つ
ている。 In addition, the female side mold plate 1 and the male side mold plate 2 are as follows:
The guide pin 5 is integrally molded on one side, and the guide groove 6 into which the guide pin 5 is slidably fitted is integrally molded on the other side to facilitate mold matching and demolding, and to improve the wear resistance of the guide pin 5 and the guide groove 6. We are trying to improve sexual performance.

雌型本体３及び雄型本体４は、夫々Be−Cu合

する。 The female body 3 and the male body 4 are each integrally molded of metal such as Be-Cu alloy to be as thin as possible and in a shape that can be fitted into the fitting openings 1' and 2'. At the time of mold matching, a molding space 8 communicating with the material injection port 7 is formed at the boundary. Further, an inserting piece 9 is fitted into the male mold body 4, and this inserting piece 9 is inserted leaving a cooling water flow path 9' between it and the male mold main body 4, and this flow path 9' is It communicates with the cooling water supply path 2'' through a communication hole 4' formed in the male body 4.

尚、図中１０は型締機構部の固定盤、１１は同
可動盤で、前記固定盤１０には雌型側型板１を、
前記可動盤１１には雄型側型板２を、夫々ネジ止
め等の取付手段１２をもつて取付ける。 In the figure, 10 is a fixed plate of the mold clamping mechanism, 11 is a movable plate, and the female mold side mold plate 1 is attached to the fixed plate 10.
The male side templates 2 are attached to the movable platen 11 with attachment means 12 such as screws, respectively.

また、１３はオイル循環室１と雌型本体３と
の間をシールするシール材である。 Further, 13 is a sealing material that seals between the oil circulation chamber 1 and the female mold body 3.

以上の構成によれば、加熱機により供給される
