The spring 6 is sleeved on the guide rod 5, one end of the spring 6 abuts on the lower mold 1, and the other end of the spring 6 abuts on the movable seat 4, which is used to drive the movable seat 4 to achieve reset movement. A lower inclined surface 42 cooperating with the upper inclined surface 31 is provided on the movable seat 4, and a second bending portion 41 is provided on the side of the movable seat 4 close to the profile positioning protrusion 14, and two guide rods 5 on one side of the movable seat 4 are provided.
