Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a quick-disassembly structure of a stamping die. Background Art

[0002] Stamping dies are specialized equipment used in cold stamping to form parts. Stamping is a process whereby a die mounted on a press applies pressure to the material at room temperature, causing it to separate or plastically deform, thereby creating the desired part.

[0003] During the stamping operation, the corresponding mold needs to be installed on the stamping machine, the lower mold is installed on the workbench through the clamping parts, and the upper mold is installed on the punch of the stamping machine. When installing the upper mold, the connecting block of the upper mold needs to be aligned and connected with the groove of the punch. Since the punch groove faces downward and the punch needs to be moved downward little by little during installation, in order to align the upper mold connecting block with the punch groove, the staff can only bend over or squat and observe the connection point upward. The operation is very inconvenient, and the docking accuracy is not high, which is not convenient for users to use.

[0004] In view of the above problems, an improved stamping die quick-disassembly structure is now designed. Utility Model Content

The height of the limiting groove 2 is twice the height of the fixed block 10.

[0033] When in use, the punch 1 is first lowered so that the limit column 12 is engaged with the inside of the limit groove 2, and then the upper mold 8 is moved. The upper mold 8 drives the fixed block 10 and the limit column 12 to move until the limit column 12 moves to the inner wall of the limit hole 13, and then the punch 1 is lowered again so that the limit column 12 is inserted into the inside of the limit hole 13, and the slot 15 is sleeved on the side wall of the fixed block 10.

[0034] The fixing mechanism includes a pin rod 9, and two first pin holes 11 for cooperating with the pin rod 9 are provided on the fixing block 10. Second pin holes 14 for cooperating with the pin rod 9 are provided on the punch 1 opposite to the two ends of the first pin holes 11.
