The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a quick-change stamping die includes a stamping fixing assembly 1, a bracket 2, a bidirectional lead screw module 3, a wedge block 4, a lifting seat 5, a first stamping cylinder 6, a second stamping cylinder 7, a horizontal cylinder 8, a first cylinder seat 9, and a second cylinder seat 10.

[0020] The bracket 2 includes an upper layer and a lower layer; the stamping fixing assembly 1 is fixed to the tail end of the upper layer of the bracket 2; a horizontal cylinder 8 is installed at the head end of the upper layer, the cylinder rod of the horizontal cylinder 8 is connected to the second cylinder seat 10, the second stamping cylinder 7 is fixed on the second cylinder seat 10, and a punch is installed at the end of the cylinder rod of the second stamping cylinder 7; the second stamping cylinder 7 is driven by the horizontal cylinder 8 to move in the horizontal direction.

[0021] The lower layer of the support 2 is provided with a bidirectional screw module 3. The movable part of the bidirectional screw module 3 is two sliders that move in opposite directions or back to back. Two wedge blocks 4 that are mirror images of each other are provided on the two sliders. The lower surface of the lifting seat 5 is provided with two wedge grooves that are mirror images of each other. The two wedge blocks 4 can slide in the two wedge grooves respectively, thereby realizing the lifting of the lifting seat 5.

[0022] A first cylinder seat 9 is installed on the lifting seat 5; a first stamping cylinder 6 is installed on the first cylinder seat 9, and a punch is installed at the end of the cylinder rod of the first stamping cylinder 6.

[0023] The upper sides of the bracket 2 are provided with rails for supporting the two sides of the second cylinder seat 10.

[0024] The lower layer of the support 2 is provided with a guide seat 11; the lifting seat 5 is provided with a guide rod 12, which moves within the guide seat 11.

[0025] The spacing between the upper and lower layers of the bracket 2 must ensure that when the cylinder rod of the horizontal cylinder 8 drives the second stamping cylinder 7 to move to the foremost position, the first stamping cylinder 6 can descend to a position that does not affect the second stamping cylinder 7.

[0026] like Figure 4 As shown, the stamping fixing assembly 1 includes an assembly bracket 1-1, a vertical cylinder 1-2, a stamping seat 1-3, a metal sheet mounting seat 1-4, a demolding piece 1-5, and an elastic clip 1-6.
