Latest Patents
Hamamoto's latest patents include a "Molding and Tentatively Retaining Mold and Method of Molding and Tentative Retention." This invention features a plurality of molds that are relatively movable with respect to a fixed mold. It molds a housing and rear holders, which are independent, within multiple cavities formed in cooperation with the fixed mold. The design allows for the rear holders to be moved relative to the housing by a pair of rear-holder tentatively retaining cylinders after molding. The amount of movement of a pair of third movable molds is predetermined to be greater than the necessary movement for tentatively retaining the rear holders. The third movable molds are then stopped at their moved positions until a predetermined time elapses.
Another patent under the same title also emphasizes the functionality of the molds. It describes how the rear holders are moved with respect to the housing by movable molds and are tentatively retained. A runner for a cavity for molding the housing remains connected to the housing through a tunnel gate. Additionally, 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.
