Abstract

PURPOSE: To enable to knock out a molded form having no dragging without utilizing a means such as a draft angle of a split mold by a method wherein only a core is withdrawn earlier while the molded form is being held in a cavity and the form is contracted freely, thereafter, the molded form is ejected out.
CONSTITUTION: When the mold is opened after the molded form A is injection molded through a spool bush 4, slide cores 9 are opend to the left and right by angular pins 5 and the female mold 8 is advanced from a core base 7 by thd resilient force of springs 16. The molded form A is retained in the cavity 11 by shoulder sections 17 and only the core 10 is withdrawn while the molded form A is contracted freely. A clearance is created between the outer surface of the form A and the inner peripheral surface of the cavity 11 according to this method, therefore, the molded form A may be ejected out of the cavity 11 without dragging the outer surface thereof when an ejector 13 is pushed out.
