Abstract
PURPOSE: To release mechanically and easily a core pin from a rubber molded article having the undercut after molding by injecting compressed air in between the rubber molded article and the core part.
CONSTITUTION: A lower die 27 opened after molding being moved to the position just above a pin plate 3, the core pin 29 is pushed up by a push-out pin 2 and the rubber molded article 30 with undercut is fitted in a fit-in hole 21 of a releasing jig 8. The molded article 30 is adsorbed with the vacuum produced by an air-sucking hole 24. Then, the compressed air from a cylinder chamber 18 and a slide pipe 20 is injected between the molded article 30 and the core pin 29 and, the opening of the molded article 30 being widened, the article 30 is released forcibly from the core pin 29.
