As described above, according to the present invention, the upper cavity forming part 107 is formed on the central surface of the upper cavity 10 having a circular outer shape, and a circular water pipe groove is formed inside so as to surround the upper cavity forming part 107. 106 is formed, and a pair of pipe-shaped water pipe mouthpieces 102 connected to the water pipe groove 106 are each attached to the outer peripheral side wall at a target position passing through the center of the upper cavity 100, and an air layer 108 is formed between the upper cavity 10 and the fixed side mold. Board 22
2 and a circular opening 222a formed in the air layer 108.
Since the circular shape of the water pipe groove 106 and the contour shape of the upper cavity forming portion 107 are configured to have the same center, for example, the water pipe 2 in the conventional technology
21 is a structure formed on a fixed side template 222 disposed outside the upper cavity 10, that is, a water pipe 22
1 is located at a far distance from the product forming section of the upper cavity 10 and is formed at unequal distances, whereas the water pipe 105 of the present invention is located at a far distance from the product forming section 107 of the upper cavity 10 that forms the product. Since they are located extremely close to each other and are circular in shape, they are equidistant, and since the heat medium flowing through the water pipes 105 flows through two semicircular paths, heat is transferred extremely quickly. The temperature approaches the temperature of the medium, and there is a certain distance between the inner peripheral side wall of the opening 222a formed in the stationary mold plate 222 outside the upper cavity 10, and heat transfer is blocked. An air layer 108 is formed, which has the effect of increasing the temperature of the upper cavity forming part. Since the temperature difference with the heat medium can be reduced quickly, it is possible to increase the cooling efficiency of the molded product and shorten the cycle time.
上キヤビテイ形成部の各部位と水管および空
気層との距離が等距離であることから、上キヤ
ビテイ形成部各部位の冷却進行温度が均一にな
り、成形品の寸法精度が向上する。 Since each part of the upper cavity forming part is equidistant from the water tube and the air layer, the cooling progress temperature of each part of the upper cavity forming part becomes uniform, and the dimensional accuracy of the molded product is improved.
長時間成形においても成形品の寸法のバラツ
キが少なくて安定可動ができる等の効果を有す
る。 Even during long-term molding, there is little variation in the dimensions of the molded product and stable movement is possible.
