The lower end of the upper die base 1 is provided with an upper clamping plate 5 and an upper pad plate 6. The lower end of the upper clamping plate 5 is provided with an upper template 4 and an upper die cutting edge plate 7. The lower end of the upper pad plate 6 is provided with a punch 8. The upper end of the upper die base 1 is provided with several upper pads 2. The upper end of the upper pads 2 is provided with an upper support plate 3. The lower end of the upper support plate 3 is provided with several springs 9. The lower ends of the springs 9 are connected to a top plate 11. A spring guide pin 10 is provided on the upper end of the top plate 11 and in the gap between two springs 9. A height equalizing screw 12 is provided on the top plate 11, passing through the top plate 11 and connecting to the upper die base 1. Several ejector rods 13 are provided below the top plate 11, and the lower ends of the ejector rods 13 are provided with an upper die inner ejector plate. 14. The upper die inner stripper plate 14 is provided with a through hole for the lower end of the punch 8 to pass through. The upper end of the lower die base 15 is provided with a lower clamping plate 18 and a lower pad plate 19. The upper end of the lower pad plate 19 is provided with a cutting punch 20. The upper end of the lower die base 15 is provided with a groove. Several rectangular springs 21 are provided in the groove. The rectangular springs 21 pass through the lower clamping plate 18. The upper end of the rectangular springs 21 is connected to the lower stripper plate 22. The lower end of the lower die base 15 is provided with a stop screw 23. The stop screw 23 passes through the lower die base 15 and the lower clamping plate 18. The stop screw 23 is fitted with a rectangular spring 24. The other end of the stop screw 23 is connected to the ejector pin 25. The ejector pin 25 passes through the lower stripper plate 22. The lower stripper plate 22 is provided with a through hole for the ejector pin 25 to pass through.

[0015] The upper mold base 1 is equipped with one end of the equal height screw 26, and the other end of the equal height screw 26 passes through the upper pad 6 and the upper clamping plate 5 in sequence and is connected to the upper mold inner stripper plate 14, which ensures the connection stability between the upper mold inner stripper plate and the upper mold base.

[0016] The upper die cutter plate 7 has a through hole at its center for the upper die inner stripper plate 14 to pass through.

[0017] The lower mold base 15 is provided with several guide pillars 29 at its upper end, and the lower end of the upper mold base 1 is provided with several guide sleeves 30 with corresponding structures at the corresponding positions of the guide pillars 29, which ensures the accurate alignment and stable operation of the upper mold base 1 and the lower mold base 15 during the mold opening and closing process.

[0018] The lower mold base 15 has several lower pads 16 at its lower end, and the lower end of the lower pads 16 has a lower support plate 17, which plays a certain role in shock absorption and support.

The equal height screw 28 is fitted with an equal height sleeve 27, which improves the stability of the lower stripper plate 22.

[0020] During operation, when the upper die base 1 closes downwards, the product is punched and trimmed by the punch 8 and the cutting punch 20. The product 31 is punched into the upper die cutting plate 7. At this time, the upper die inner ejector plate 14 is pushed upwards. The upper die inner ejector plate 14 drives the ejector rod 13, which in turn drives the top plate 11 upwards, compressing the spring 9. When the upper die base 1 moves upwards, the spring 9 is released, and the top plate 11 pushes the ejector rod 13 downwards, pushing the upper die inner ejector plate 14 out of the upper die cutting plate 7. At this time, the product 31 is ejected, achieving the stripping effect. Depending on the stripping force required for the actual product, the spring 9 can be replaced with a urethane and nitrogen spring.
