  • Lid closer for injection mold
    Patent number: 8083978
    Abstract: Injection molded parts having bodies and lids connected by living hinges have the lids closed against the bodies during an opening sequence of mold plates. The lid closing mechanism is arranged in an intermediate plate disposed between a movable B plate and a fixed A plate. Movable and fixed cavities can meet within the intervening plate where a lid closer accomplishes lid closing as mold plates separate during mold opening. Accomplishing the lid closure during a mold opening sequence avoids any increase in the mold cycle time.
