[0016] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, in the existing stamping die, the punch is installed on a fixed block, and the fixed block is fixed in the splint. When replacing the punch, the die needs to be dismantled, that is, the back plate corresponding to the splint and the punch and other parts, so that the fixed block and the punch can be dismantled and replaced.

[0019] Combination Figure 2-Figure 3 As shown, the stamping die with a quick-change structure in this embodiment also has a main body composed of an upper die portion and a lower die portion that are relatively arranged, and the processing object is placed between the two for punching processing.

[0020] Among them, the upper mold part includes an upper mold base 11, an upper pad 12, a clamping plate 13, a back plate 15 and a male mold plate 14 which are arranged in sequence, and the lower mold part includes a female mold plate 21, a lower pad 22 and a lower mold base 23 which are arranged in sequence, wherein the male mold plate 14 and the female mold plate 21 are arranged relatively to each other, wherein a punch 31 is arranged in the upper mold part, and a punch hole 231 is arranged through the lower mold base 23 corresponding to the position of the punch 31, and the punch 31 punches the processing object, and the waste is discharged through the punch hole 231.

[0021] Specifically, a notch is provided on one side of the upper pad 12, and a connecting block 41 is filled in the notch. The connecting block 41 just fills the notch, and the connecting block 41 and the upper pad 12 are detachably connected by fasteners such as bolts entering from the side. The connecting block 41 is just located above the punch 31 and between the upper die base 11 and the clamping plate 13. Therefore, the connecting block 41 lowers the punch 31 in a locked state to limit and fix it.

[0022] Specifically, the punch 31 is disposed inside the clamping plate 13 , the back plate 15 and the male mold plate 14 and partially penetrates to the outside of the male mold plate 14 .

[0023] In addition, a discharge hole 111 is provided through the upper die seat 11, and the position of the discharge hole 111 corresponds to the position of the punch 31. The punch 31 can pass through the discharge hole 111 to the outside of the upper die portion. A limit rod 112 is detachably provided in the discharge hole 111, and the lower end of the limit rod 112 abuts against the connecting block 41.

[0024] When replacing the present invention, the connecting block 41 is disassembled and taken out, and the limiting rod 112 is taken out by means of a magnet, etc., so that the punch 31 can be lifted up from below the punch 31 and discharged from the discharge hole 111, and then a new punch is installed, and then the connecting block 41 and the limiting rod 112 can be reinstalled.

[0025] All the methods described herein can be performed in any suitable order. Any and all examples used, or exemplary language provided herein (such as "for example") are merely to better illustrate the present invention, and are not intended to limit the scope of the present invention, unless the claims are included.
