  • Patent number: 5961910
    Abstract: A moving mold 100 consisting of slidable housing molds 110 and 110 and retainer molds 120 and 120 and a fixed mold 200 pairing with the moving mold 100 are used to mold a housing 20 and retainers 30a and 30b in resin at the same time. When the fixed mold 200 and the moving mold 100 are opened, the housing molds 110 and 110 are opened and a space is formed between the housing 20 and the retainers 30a and 30b to be fitted to each other. The retainers 30a and 30b are pressed against the housing 20 with the retainers 30a and 30b held in the retainer molds 120 and 120 from both the left and right sides, whereby the housing 20 and the retainers 30a and 30b are assembled.

  • Patent number: 5915760
    Abstract: A movable mold is movable toward and away from a fixed mold so as to close and open the mold. The fixed mold includes an intermediate plate facing a movable-side mold plate. This intermediate plate has a retainer-molding recess which cooperates with the movable-side mold plate to form a retainer-molding cavity, and a core pin, which cooperates with a housing-molding recess to form a housing-molding cavity, is mounted on the intermediate plate. A retainer, molded in the molding cavity, is moved downward by an ejector pin into a position where the retainer is disposed coaxial with a housing. Then, the two molds are again closed together, so that the housing and the retainer are connected together, and then this assembled product is taken out.

  • Patent number: 5894661
    Abstract: When a stationary metallic mold and a movable metallic mold are closed, a housing is molded having a retainer insertion hole by the existence of a sliding mold. A retainer is also molded. First, when only the metallic mold is opened, the core pin is withdrawn, and the sliding mold is withdrawn in the longitudinal direction by the cam action of the angular pin, so that the molding portion is withdrawn from the retainer insertion hole. Successively, the sliding mold is relatively drawn out to the front of the advancing and withdrawing passage together with the stationary metallic mold, and the advancing and withdrawing passage becomes open. Next, an auxiliary sliding mold is advanced, and the retainer held by the auxiliary sliding mold is inserted into the retainer insertion hole and temporarily assembled to the housing. It is possible to insert the retainer straight into the retainer insertion hole. The finished product is protruded to the front of the movable metallic mold by the protruding pin.

  • Patent number: 5647777
    Abstract: A connector assembly includes a connector housing and a retainer that straddles the connector housing. The retainer is attached on the upper face of the connector housing. The retainer includes engagement projections, which engage with terminal pieces in the connector housing, to prevent the retainer from slipping out of the connector housing. The dimensions of the connector are set so a gap is formed between the engagement projections and the outer face of the connector housing. A separation plate of a molding die can be positioned in the gap, so the connector housing and the retainer can be simultaneously molded in an assembled relationship with the retainer separated from the connector housing. A molding die and method of producing the connector assembly are also disclosed.
