Abstract
PURPOSE: To easily perform a titled mold releasing by a method wherein after a foamy molding is molded, a mold is slightly opened, and a mold releasing screen is lowered between molds and thereafter, the molding is released from the mold off the screen by means of a compressed air.
CONSTITUTION: Foamy heat plastic resin grains are foamily molded by means of a moving mold 20 and a fixed mold 10. Next thereto, while a molding A is attached to the mold 20 at one hand, the mold is slightly opened and a mold releasing screen 5 is lowered in a small gap between the mold 10 at the other hand and the molding A. Thereafter, air is injected from the mold 20 at a hand to release the molding A off the mold releasing screen 5 and at the same time the molding A is made to fall to be taken out as a foamy molding. Without using a mold releasing knock out pin, the mold releasing is performed easily to take out a product.
