METHOD FOR MANUFACTURING WATERPROOF CONNECTOR HOUSING

摘要

PROBLEM TO BE SOLVED: To integrally mold a ring-shaped sealing part in a connector part continuously even in the case of a small-sized waterproof connector and to reduce deburring steps. SOLUTION: A slit 15 is formed to the bottom part of a hood part and the remaining mold part is replaced with a rubber mold with a runner part 80 which allows the injection of a molding material in a direction parallel to the mold opening/closing direction in such a state that the obtained primary molded body is held to an intermediate mold part 6 to inject an unvulcanized rubber in a ring-shaped cavity 70 from the runner part 80 through the slit 15. Since the runner part 80 is arranged so that the molding material can be injected in the direction parallel to the mold opening/closing direction, the trouble causing the interference between a molding machine and the runner part 80 can be avoided. Further, the interference between the primary molded body and the runner part 80 can be avoided by the presence of the slit 15. COPYRIGHT: (C)2004,JPO&NCIPI
