Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1:

[0024] Please refer to FIGS. 1-4 in combination. A stamping die structure includes a base 1. An installation groove 2 is opened in the middle of the top of the base 1. An installation block 10 is clamped inside the installation groove 2. The shape and size of the installation block 10 are adapted to the shape and size of the installation groove 2, and the installation block 10 is in close fit with the inner wall of the installation groove 2. The bottom of the installation block 10 is fixedly connected to a lower mold 11. An installation hole 3 is opened in the top of the base 1. A magnet 4 is fixedly connected inside the installation hole 3. Connecting rods 5 are fixedly connected to both sides of the top of the base 1. A return spring 6 is arranged outside the two connecting rods 5. A connecting block 14 is slidably connected to the upper side of the surface of the two connecting rods 5. Limiting holes 15 are opened on the surfaces of the two connecting blocks 14. The diameter of the limiting holes 15 is the same as the diameter of the connecting rods 5, and the connecting rods 5 are in close fit with the inner wall of the limiting holes 15. The side of the two connecting blocks 14 close to each other is fixedly connected to a fixing plate 12. A pressing groove 13 is opened in the middle of the top of the fixing plate 12. The bottom of the fixing plate 12 is fixedly connected to an upper mold 16. An installation bracket 7 is fixedly connected to the rear side of the base 1. A hydraulic rod 8 is fixedly connected to the top of the installation bracket 7. The bottom of the hydraulic rod 8 is fixedly connected to a pressing head 9. The position of the pressing head 9 is directly above the position of the pressing groove 13, and the diameter of the pressing head 9 is adapted to the diameter of the pressing groove 13.

[0025] Working principle: When it is necessary to replace the upper die 16 and the lower die 11, the staff can detach the connecting block 14 from the connecting rod 5 by lifting it upward, thereby disassembling the upper die 16. By lifting the lower die 11 upward to drive the installation block 10 to disengage from or insert into the installation groove 2, the lower die 11 can be quickly separated from the base 1. At this time, the staff inserts the new upper die 16 and lower die 11 into the installation groove 2 and the limiting rod respectively to complete the replacement work. Then the staff starts the hydraulic rod 8, and the hydraulic rod 8 pushes the lower pressure head 9 downward. The lower pressure head 9 pushes the upper die 16 into the lower die 11 through the lower pressure groove 13 to complete the stamping. As the hydraulic rod 8 retracts, the limiting spring pushes the upper die 16 back to its original position through the connecting block 14.

[0026] Compared with the related technology, a stamping die structure provided by the present utility model has the following beneficial effects: By setting the installation block 10, installation groove 2, limiting hole 15, connecting rod 5, etc. to cooperate with each other, the upper die 16 is disassembled by driving the connecting block 14 to disengage from the connecting rod 5. By driving the installation block 10 on the lower die 11 to disengage from or insert into the installation groove 2, the lower die 11 can be quickly separated from the base 1. The replacement process is fast and convenient, and it is easy to use.
