Abstract
PURPOSE: To provided uniform cooling effect to plastic moldings by a method in which a molding is pressed from inside by projecting a piston while the molding is hot and after cooling the molding, the molding is released from a chuck by returning the piston.
CONSTITUTION: By projecting a piston 22 provided for pressing on a plastic molding 17, when the plastic molding 17 just injected from an injection molder is in hot state, the side wall of the molding 17 is pressed from inside to outside and the pressed condition is kept for a fixed period of time. And, by switching the flow of compressed fluid from a piston-projecting pressure chamber formed at basal portion inside the cylinder 21 to a piston-returning pressure chamber formed at tip portion inside the cylinder 21 after cooling the molding 17, the piston 22 is restored to its original position and the molding 17 is released from a chuck 20.
