  • Patent number: 5629031
    Abstract: A remover for an injection-molded article includes a front mold and a movable mold half connected to the front mold freely movable in a forward and backward direction and adapted to define an injection-molding cavity by association with the front mold. A detecting arrangement continuously detects a start time, a finish time, and a quantity of travel of the movable mold half. An ejector forces out a molded article at a mold-open finish position. A removing mechanism includes a grasping member for grasping the molded article. A control arrangement performs numerical control of the removing mechanism, so that when the detecting arrangement detects the finish time of the mold-open operation of the movable mold half, the removing mechanism moves the grasping member from a predetermined waiting position to a position for removing the molded article.
