Title: Manufacture of molded item and mold therefor
Inventor: KIKUCHI HIDETOSHI
IPC: B29C45/43
Filed: 1983-06-20
Abstract: PURPOSE:To prevent a molded item from adhering to a cavity or core that has no ejector pin, by causing the pressure between the core or cavity and the molded item to be a positive pressure, and taking out the molding item by ejector pins. CONSTITUTION:When an item W molded by a mold consisting of a core 1 and a top force 3 by injection molding is to be removed from the mold, the force 3 is moved away from the core 1 and at the same time compressed air is supplied via a hose 5. Then the air flows via a check valve 4 and its pressure acts between the force 3 and the molded item W so that the negative pressure produced when they are separated can be cancelled and at the same time the pressure between them becomes positive. As a result, the molded item W can be separated easily from the force 3. Thereafter, ejector pins 2 are pressed to the molded item W to remove the molded item W from the core 1.
