ケット部成形型。This is a pocket mold for a plastic cage for roller bearings that is injection molded by radial die cutting, and the outer surface has an inner circumferential surface parallel to the cage axis and a vertical surface perpendicular to the axis. A pair of L-shaped moldings having an inclined surface connected to the vertical surface on the outside of the vertical surface, and a notch provided on the opposite side of the inner circumferential surface of the axial end portion away from the vertical surface. It consists of a mold, at least one pair of parallel surfaces perpendicular to the axis, and a core having an inclined surface that extends outward in the radial direction and is continuous with the parallel surfaces, and is arranged with the vertical surfaces of the L-shaped shape facing each other. , the parallel surfaces of the core cooperate with the vertical surface, and the pair of L-shaped molds are tightly connected to the parallel surfaces by a tension spring, and the core is allowed to move in the radial direction. , the L-shaped mold allows axial movement and corresponding radial movement by cooperation between the slope of the L-shaped mold and the parallel surface of the core. Plastic cage pocket mold.
