成形型のアンダーカツト処理装置。 In a mold for molding a molded product having an undercut portion on the outer periphery in a direction in which the die cutting direction intersects with the opening/closing direction of the mold body, the outer peripheral surface of the cylindrical core forming the undercut portion is tapered. A tapered hole is formed in the mold body, and the core is divided into a plurality of parts in the circumferential direction, and an elastic member is provided to bias the divided cores radially outwardly. is arranged so as to move in the direction of protrusion and retraction as the mold body is opened and closed, and when the mold is opened after molding, the core moves in the direction of protruding from the tapered hole and is expanded by the elastic member,
An undercut processing device for a molding die configured to release the core from the molded product.
