Manual removal of the workpiece is prone to damage due to manual operation errors, and the efficiency of manual removal of the workpiece is low, which seriously affects the injection molding efficiency of the two-color injection molding device. The utility model uses a driving motor 51 to drive the driving wheel 52 and the driven wheel 54 to rotate, so that the screw rod 551 fixed on the top surface follows the rotation, and the inner threaded sliding rod 552 connected to the surface moves upward, and its top end protrudes through the sliding groove opened on the surface of the injection mold 4, so as to eject the injection molded workpiece and avoid damage to the workpiece caused by manual removal.
