[0032] The adjustment mechanism includes a first positioning assembly, a second positioning assembly, a third positioning assembly, and a fourth positioning assembly. The first positioning assembly and the second positioning assembly are arranged on both sides of the forming punch 10 along the first direction, and are used to adjust the position of the forming punch 10 in the first direction. The third positioning assembly and the fourth positioning assembly are arranged on both sides of the forming punch 10 along the second direction, and are used to adjust the position of the forming punch 10 in the second direction ( Figure 1 and when the upper mold base 2 is moved along the third direction ( Figure 1 The forming punch 10 and the forming die 20 correspond to each other along a first direction to press-fit the stamped product, and the first direction, the second direction and the third direction are perpendicular to each other.

[0033] The stamping die provided in the present application changes the position of the forming punch 10 in the first direction and the second direction by setting an adjustment mechanism, so that when the upper die base 2 is stamping downward, the forming punch 10 and the forming die 20 correspond to each other along the first direction and crimp the stamped product, thereby avoiding the module from generating lateral force due to pressure, causing movement or tilting, making the shape of the stamped parts not meet the requirements and reducing the stamping quality.

[0034] In some embodiments, reference Figures 1 to 4, the first positioning component includes a first blade wiping block 30, a first blade abutting block 31 and a first base 32. A first connecting portion 33 is provided at the bottom of the first blade abutting block 31.
