The movement of the anti-collision plate 7 will cause the movable plate 5 to move backwards. During the movement, the movable plate 5 will cause the four first movable blocks 401 to move backwards. The movement of the four first movable blocks 401 will cause the four movable rods 402 to rotate. The rotation of the four movable rods 402 will cause the top two second movable blocks 403 and the bottom two second movable blocks 403 to move toward the opposite ends and cause the four buffer springs 404 to be deformed. Under the elastic action of the four buffer springs 404, the impact force received by the movable plate 5 and the mounting block 2b is buffered, thereby protecting the mold 1.
