[0023] When in use, start the lifting device 3, the output shaft of the lifting device 3 drives the upper plate 4 and the upper mold 6 to move downward, and the upper traction column 12 also moves downward accordingly. The position of the upper mold 6 is symmetrically arranged with the lower mold 8. Since the upper traction column 12 is connected to the traction hole of the lower traction column 13, the lower traction column 13 also plays a limiting role, so that the upper traction column 12 can only slide up and down in the traction hole. Due to the frequent collision and friction between the bottom surface of the upper traction column 12 and the lower traction column 13 during the stamping process, a spring is sleeved on the outer wall of the upper traction column 12, which plays a role of shock absorption to a certain extent and prolongs the service life. In order to avoid the upper traction column 12 and the lower traction column 13 being insufficient when the upper mold 6 is stamped downward, resulting in shaking, an upper limit column 14 and a lower limit column 15 are also provided.

The spring plays a role of The function is the same as that at the upper traction column 12. The upper traction column 12, the lower traction column 13, the upper limit column 14 and the lower limit column 15 can well limit the position of the upper mold 6 during the stamping process. When different parts need to be stamped, different upper molds 6 and lower molds 8 need to be selected according to the parts. When the upper mold 6 is too large, the cylinder 9 starts to move, pushing the upper sliders 10 on the left and right sides to the left and right sides, and at the same time driving the upper traction columns 12 on both sides to move to both sides. Since the upper traction column 12 is connected to the lower traction column 13, the lower slider 11 can be driven by the lower traction column 13 to slide to both sides. Since the front and rear sides of the lower slider 11 are also provided with side sliders 25, the side sliders 25 can be slidably arranged in the side slide grooves 24, and the movement is smoother. The upper mold 6 and the lower mold 8 are installed on the upper slider 10, the lower slider 11, the support plate 7 and the upper top plate 4 through a number of mounting holes on the upper slider 10 and the lower slider 11.

[0024] When disassembly is required, pull the pull ring 20 by hand, and the pull ring 20 is connected to the fixed block 19. At this time, the positioning pin shaft 21 moves to the left and right, and the pin head 22 also moves to both sides. At this time, the spring 23 on the positioning pin shaft 21 between the pin head 22 and the inner wall of the accommodating chamber 16 is compressed, and the pin head 22 leaves the first positioning pin hole 18. At this time, the support plate 7 can be directly removed from the base 1, and then the lower mold 8 can be removed from the support plate 7, which can facilitate the replacement of parts and cleaning.
