Usual injection molding devices transfer the injectors by hydrauric cylinder. But in case of large injection molding this type can hardly applied and has some problem in nozzle touching power. By constructing mechanically injection stroke adjusting, and length ening can be performed without hydrauric support. By using mechanical transfer device, undesirable nozzle touching power that caused by the hydrauric device can be eliminated. And by hydrauric compensating, precision, the forming block can be enhanced. As adjusting and legnthening of injection stroke are easy, injection capability can be increased.
