成形型の二段押出装置。 A main extrusion member that is provided on one side of the first and second molds that form a cavity for molding a molded product when the molds are matched and is moved in the extrusion direction after opening the mold, and this main extrusion member. a main knock-out member provided on a member that penetrates the one mold and protrudes into the cavity to mold a part of the molded product; a sub-extrusion member disposed between the main extrusion member and the one mold; a sub-knockout member provided on the sub-extrusion member and having a tip thereof facing into the cavity by passing through the one mold; and an elastic member provided between the main extrusion member and the sub-extrusion member;
By moving the main extrusion member in the extrusion direction after opening the mold, the sub extrusion member is moved in the extrusion direction, and the molded product attached to one of the molds is removed by both the main and sub knockout members. As the molded product is extruded from the one mold, the sub-extrusion member moves in the extrusion direction by the elastic force of the elastic member, and the sub-knockout member moves the molded product into the mold. A two-stage extrusion device for a mold, characterized in that the product is extruded from a main knockout member.
