PURPOSE:To mold a housing excellent in a hermetically close property, by providing a press pin equipped with a spring in a mold and filling the mold with a resin against the energizing force of the spring. CONSTITUTION:A press pin 14 is pushed up by the energizing force of a spring 15 to determine the position of a terminal 13. A resin is injected from a gate to fill a cavity 12. When the cavity 12 is filled with the resin and the internal pressure thereof reaches injection pressure, the filling of the resin advances while the press pin 14 overcomes the energizing force of the spring 15 to be pushed back. When the protruding part 19 of the press pin 14 is brought into contact with the step part of a groove 18, the filling of the resin is stopped. Since the resin is allowed to fill against the energizing force of the spring 15 of the press pin 14 to be solidified, a housing excellent in a hermetically close property can be molded. |
