Abstract

PURPOSE: To facilitate a making of completely closed insert molding means by retracting a holding pin in response to an injection of molding resin into a cavity via gate.
CONSTITUTION: Insert holding device is constituted by holder pins 2, 2 for holding insert 1, a cylinder 22 projecting into a cavity 3 formed between the upper and lower mold plates, and a stop pin 23 of a holding pin. Molding resin A is injected into a cavity 3 at an outer circumference of the insert 1, the resin A is introduced into an enclosing cavity 6 enclosed by a leading end surface of the pin 2 and an inner circumferential surface of the insert 1 from a secondary gate 5 at the leading end of the pin 2 filled in the cavity 6. A molding pressure of the and resin A is applied to the end surfaces of the pins 2, 2, and the pins 2, 2 are retracted by this pressure. When an injection of the resin A is completed, the injected condition is kept until a curing of the resin A is finished. Upon completion of the curing of the resin, the molded parts or molds are opened, the pin 2 is further retracted and the finished product is pushed out by the pin 21.
