[0019] The following is a clear and complete description of the technical solutions in this utility model application, in conjunction with the accompanying drawings. Obviously, the applications described are only part of the applications in this utility model, not all of them. All other applications obtained by persons of ordinary skill in the art based on the applications in this utility model without inventive effort are also within the scope of protection of this utility model.

[0020] Reference Figure 1 and Figure 2 The utility model discloses a metal stamping die that is easy to disassemble and assemble:

[0021] like Figure 1 、 Figure 2As shown, the present application discloses a metal stamping die that is easy to disassemble and assemble, including an upper die mechanism and a lower die mechanism connected by a support column 8. The upper die structure includes an upper die base 3, an upper pad 5 and an upper splint 6 that are fixed by bolts from top to bottom, and the lower die structure includes a lower die base 9, a lower pad 10 and a lower template 11 that are fixed by bolts from bottom to top. A rectangular opening is hollowed out in the middle of each layer of the upper die structure, and a straight handle 1 is inserted into the rectangular opening. The upper end face of the upper die base 3 is bolted with a straight handle chuck 2, the lower end face of the upper splint 6 is bolted with a stripper plate 7, and the upper end face of the lower template 11 is bolted with a guide plate 12; a pressure spring 4 is arranged between the upper die base 3 and the stripper plate 7, the upper end face of the pressure spring 4 is in contact with the lower end face of the stripper plate 7; a punch 13 is embedded in the interior of the upper splint 6, and the lower end face of the punch 13 is bolted to the stripper plate 7.

[0022] Specifically, stamping components for stamping are provided in the upper die mechanism and the lower die mechanism. These stamping components are the key to realizing the stamping operation. A pressure spring 4 is provided between the upper die seat 3 and the stripping plate 7 in the upper die mechanism. The pressure spring 4 can automatically restore the upper die mechanism to its initial position after the stamping is completed, thereby improving the efficiency and accuracy of the stamping operation.

[0023] Furthermore, the lower end face of the straight handle 1 is connected with a thrust washer, which is embedded in the mounting position in the middle of the lower template. This design can enhance the stability of the straight handle 1 and prevent it from shaking or falling off during the stamping process, thereby improving the accuracy and safety of the stamping operation.

[0024] Furthermore, the upper and lower end faces of the pressure spring 4 are provided with mounting holes, which are used to fix the pressure spring 4 on the upper die base 3 and the stripper plate 7. By adopting this fixing method, it can be ensured that the pressure spring 4 will not be displaced or fall off during the stamping process, thereby ensuring the stability and reliability of the mold; a punch 13 is embedded in the interior of the upper clamping plate 6, and the lower end face of the punch 13 is mounted on the stripper plate 7 by bolts. This design enables the punch 13 to perform stamping operations stably and is easy to replace and repair; support rods are detachably installed on both side edges between the upper die base 3 and the stripper plate 7. These support rods can enhance the stability of the upper die mechanism and prevent deformation or damage during the stamping process.

[0025] Furthermore, the cross-sectional lengths of the upper die base 3, the stripping plate 7 and the lower die base 9 are the same, and positioning structures are provided at the connection between the upper die mechanism and the lower die mechanism. These positioning structures are used to ensure the accurate positioning of the upper die mechanism and the lower die mechanism during the stamping process. By adopting this positioning method, the accuracy and stability of the stamping operation can be further improved.

[0026] Furthermore, the positioning structure is specifically a positioning pin 701 and a positioning hole used in conjunction with the positioning pin 701, which can effectively prevent the mold from being misplaced or offset during the stamping process.
