Title: Injection molding having undercut part and manufacture thereof
Inventor: YABUSHITA SHOZO
IPC: B29C45/44
Filed: 1990-09-27
Abstract: PURPOSE:To reduce the material cost of a mold and working cost, enhance the strength of the mold, and thus improve the durability by projecting a hook on the outside of tip of an undercut part and providing a hook piece interlocked with a slide mold during mold releasing. CONSTITUTION:On the upper surface of a slide core 5, steps 12 are provided continuously on the curved surface 5a, and recessions 13 are provided on the tip of the steps. When a molding material is injected from a predetermined pouring port, a molding 7 is molded on the cavity and a continuous hook piece 14 is molded on the undercut part 9 of the molding 7 in the steps 12 of the upper surface of the slide core 5 and recessions 13. After the completion of the injection molding, when the slide core 5 is allowed to slide in the direction of arrow A, the hook piece 14 is pulled by the slide core 5 and thereby the undercut part 9 of the molding 7 continuous to the hook piece 14 is also moved in the direction of arrow A, thus, a gap is produced between the undercut part 9 and the curved surface 8a of the stationary mold 1. By maintaining the gap appropriately, as the movable mold is allowed to comes down, the undercut part 9 of the molding 7 is readily released from the stationary mold 1.
