[0026] Working principle: After the headlight is stamped and cooled, the staff starts the motor 45. The output end of the motor 45 drives one of the rotating shafts 41 to rotate. The rotation of the rotating shaft 41 drives one of the gears 44 to rotate. The two gears 44 rotate in opposite directions, and then the two rotating shafts 41 drive the two rotating shafts 41 to rotate in opposite directions. The two demoulding rollers 43 rotate upward, and then the two demoulding rollers 43 push the bottom plate 3 upward inside the forming mold 1, so that the cooled headlight can be pushed up from the inside of the forming mold 1. After pushing it up, the staff can take the headlight out of the inside of the forming mold 1.
