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. A mold-close operation is started after the molded article held by the grasping member is moved out of the mold area, and the grasping member is controlled to move and withdraw from the mold area. The control arrangement supplies a mold-close signal to control the movable mold half to start moving in the direction corresponding to the mold-close operation at a predetermined timing alter start of withdrawal of the grasping member from the mold area, whereby the mold-close operation finishes when withdrawal of the grasping member from the mold area finishes.
