する射出成形装置。[Scope of Claim for Utility Model Registration] An injection molding device for molding an automobile bumper having ribs extending vertically with a predetermined gap from the rear surface of the bumper body, the upper part for molding the front side of the bumper body. a mold, a lower mold for molding the back side of the bumper body, and a first mold which is provided so as to be movable relative to the lower mold in a direction in which the bumper is released from the mold, and which releases the molded bumper from the lower mold. The first ejector pin is driven in two stages: an ejecting position and a second ejecting position in which the bumper is further protruded upward from the first ejecting position, and the first ejector pin is movable relative to the lower mold in the mold release direction. a second ejector pin that is provided and releases the bumper from the lower mold in conjunction with the movement of the first ejector pin to the first ejecting position, and the second ejector pin has an upper end that releases the bumper from the lower mold. A rib molding core is provided which has a protruding surface for molding the rib and forms a cavity for molding the rib together with the lower die, and the rib molding core has a side surface opposite to the center of the bumper of the rib. A rib molding part is formed, which has a molding surface to form the rib and a molding surface to form a gap surface in the rib, and is open toward the center of the bumper, and the lower mold has a side surface of the rib on the bumper center side. An injection molding device characterized in that a molding surface is formed.
