摘要： An injection compression molding method of a lens is provided, where a toggle link mechanism (65) is actuated to close a molding die (50) and a movable die plate (64) is moved to a position establishing a cavity thickness of greater than a thickness of an article to be molded while the die is closed. After injecting a molten resin into the cavity, the molten resin is sealed in the cavity and the toggle link mechanism (65) is actuated to advance the movable die plate (64) toward a fixed die plate (61), the relative position of a rear die plate (62) and the movable die plate (64) is made constant at a position where extension of a tie bar (63) becomes a predetermined value, and the molten resin is cooled for a predetermined time after completion of pressurizing the resin.

摘要： A mold for a plastic lens that arranges an insert member inside a cavity formed between a pair of halved molds, injects and fills molten raw material resin to mold a plastic lens having a predetermined shape, integrally with the insert member. The insert member is arranged on a molding surface on one of the halved molds, a notch to be engaged with a positioning tab formed at a periphery of the insert member is engraved on one parting surface of the halved mold, overlapping with a gate position. Positioning of the insert member is performed by engaging the positioning tab with the notch. With this configuration, in molding a plastic lens having an insert member by injection molding including insert molding, positioning of the insert member is performed at the gate position without deteriorating the quality of a molded product and without increasing the load of post-processing after molding.
