发明名称 Resin molding method in which a movable cavity piece allows a direct resin feed
摘要 A resin molding method by which resin is filled into a cavity while an article to be molded is clamped between upper and lower molding dies, wherein a cavity indentation is formed from an end face of a cavity piece provided in a cavity hole formed in the molding piece and of an internal wall surface of the cavity hole, the method including the steps of: arranging the cavity piece provided in the lower molding die so as to be movable in a direction in which the molding dies are opened or closed; covering a parting surface of each of the resin molding dies with a release film; sucking the release film from an area in the vicinity of an inner bottom surface of the cavity indentation of the lower molding die, to thus form a storage section for storing resin used for a molding operation within the cavity hole; feeding a required amount of resin to the storage section; setting the article on the lower molding die and clamping the article between the resin molding dies; and pressing the cavity piece of the lower molding die to a resin molding position to thus cause the resin provided in the cavity to set, thereby molding the article with resin.
