Abstract
PURPOSE: To release a molded article smoothly and surely by a method wherein a slide core engaged with the undercut part of the molded article and a movable die are moved in the direction of die opening and then the slide core is expanded and opened by an angular pin.
CONSTITUTION: A molding material is injected into a cavity 18 through a sprue gate 19 and molded, thus a molded article A with an undercut part (a) being obtained. Next, a movable die 16 is moved in the direction of die opening, while a slide core 17 being pushed out by a required distance V by means of a push pin 20 energized by a coil spring 21, and thus the molded article A is released from a fixed die 15. Then, after the die 16 is further moved in the direction of die opening and the core part 16a of the die 16 is released from the article A, the slide core 17 is expanded and opened by making an angular pin 22 touch the outward inner wall of a slant hole 23, thereby the molded article A being released from the slide core 17 and the core part of a fixed die 3.
