装置。 In an injection molding device in which a film is inserted into a cavity of a mold and a resin is integrally bonded to the back side of the film by injection molding, a spring-loaded presser pin is used to press the film into the mold. A plurality of presser pins are arranged to be slidable and press the film, and a stepped portion is provided at the tip of the presser pin, and when the molten resin is press-fitted into the mold, the presser pin retreats against a spring force.
