发明名称 RESIN INSERT MOLDING OF METAL MEMBER AND CONNECTOR BLOCK FOR INJECTOR OF INTERNAL COMBUSTION ENGINE
摘要 PURPOSE:To mold a connector block for an injector by a simple molding process wherein a pinhole and an isolating layer are provided to a core member having a pinhole in which the holding pin provided to a mold cavity in a protruding state is inserted and the projection internally in contact with the inner wall of the cavity of perform the insert molding of the core member. CONSTITUTION:The holding pin 17 protruding into a cavity 16 is provided to the lower mold 15 of a mold. A core member 7 has a holding pinhole in which the front half part of the holding pin 17 is inserted and the positioning projection 11 in contact with the inner wall of the cavity 16 and an isolating layer 13 is provided between the holding pin 17 and the holding pinhole 12 to house and set a metal member 2. The core member 7 having the metal member 2 received therein is inserted in the cavity 16 to perform the insert molding of the core member. Since this molded object has the isolating layer 13 between the extracted hole 25 of the holding pin 17 left after molding and the metal member 2, the contact of the open air/moisture with the metal member 2 is cut off and the waterproofness and airtightness of that region are ensured.
