A molding and tentatively retaining mold of the invention has a plurality of molds which are relatively movable with respect to a fixed mold, and molds a housing and rear holders and , which are respectively independent, in a plurality of cavities formed in cooperation with the fixed mold. When the rear holders and are relatively moved with respect to the housing by a pair of rear-holder tentatively retaining cylinders after molding, and are tentatively retained, the amount of movement of a pair of third movable molds is set to be greater by a predetermined amount than an amount of movement necessary for tentatively retaining the rear holders and , and the third movable molds after movement are stopped at the moved positions until a predetermined time elapses.

Molding and tentatively retaining mold and method of molding and tentative retention

A molding and tentatively retaining mold of the invention has a plurality of molds which are relatively movable with respect to a fixed mold, and molds a housing and rear holders and which are respectively independent, in a plurality of cavities formed in cooperation with the fixed mold. When rear holders and after molding are relatively moved with respect to a housing by movable molds and and are tentatively retained, a runner for a cavity for molding the housing is kept connected to the housing through a tunnel gate In addition, a portion of the fourth movable mold for forming the cavity in the housing is kept fitted to the housing as it was during molding.
