However, the existing stamping die frame only has positioning pins around the die frame to limit the aluminum plate. When facing the high-speed feeding and unloading operation of the fully automatic press, the limiting device of the traditional die frame cannot completely clamp the aluminum plate. The deviation of the position of the aluminum plate will cause the character mold to be pressed off, increasing the scrap rate of the license plate during the production process. The aluminum plate with position deviation will squeeze the feeding and unloading device and the die frame of the fully automatic press during the operation process, affecting the operation of the production equipment.
