Abstract: A molding and tentatively retaining mold 10 of the invention has a plurality of molds which are relatively movable with respect to a fixed mold, and molds a housing 31 and rear holders 32 and 33, which are respectively independent, in a plurality of cavities formed in cooperation with the fixed mold. When the rear holders 32 and 33 are relatively moved with respect to the housing 31 by a pair of rear-holder tentatively retaining cylinders 19 after molding, and are tentatively retained, the amount of movement of a pair of third movable molds 14 is set to be greater by a predetermined amount than an amount of movement necessary for tentatively retaining the rear holders 32 and 33, and the third movable molds 14 after movement are stopped at the moved positions until a predetermined time elapses.

When rear holders 32 and 33 after molding are relatively moved with respect to a housing 31 by movable molds 12 and 15 and are tentatively retained, a runner 20 for a cavity for molding the housing 31 is kept connected to the housing 31 through a tunnel gate 20a. In addition, a portion 15a of the fourth movable mold 15 for forming the cavity in the housing 31 is kept fitted to the housing 31 as it was during molding.

Diameters of runners serving as channels for the charging of a resin material into cavities of a molding and tentatively retaining mold are set for the respective cavities such that the charging of the resin material into the cavities is completed substantially at the same time.
