[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0025] Example 1

[0026] This utility model provides, for example Figures 1-6 As shown, a multi-die stamping machine includes: a stamping machine body 1, a placement groove 2 is provided on the surface of the stamping machine body 1, a guide rod 3 is provided on the surface of the placement groove 2, a positioning tube 4 is sleeved on the surface of the guide rod 3, and a pull plate 5 is provided on the side of the positioning tube 4.

[0027] The fixed base 6 has a positioning groove 7 on its surface and a lower mold 8 on its surface.

[0028] Mounting plate 9, a first bearing 10 is provided on the side of mounting plate 9, a support rod 11 is provided inside the first bearing 10, the surface of the support rod 11 is threaded, and a limit nut 12 is screwed onto the thread;

[0029] The stamping machine body 1 can be used in conjunction with the lower die 8 to stamp products. When it is necessary to change to a different lower die 8, simply press down the pull plate 5 to move the positioning tube 4 down, so that the positioning tube 4 can be disengaged from the positioning groove 7, thus losing its limitation on the fixed seat 6, and thus the fixed seat 6 can be rotated easily. After rotating the fixed seat 6, it can be fixed by the positioning tube 4. Then, by rotating the fixed seat 6, different lower dies 8 can be easily replaced, so that the stamping machine body 1 can be used in conjunction with the new lower die 8 for processing.

[0030] Example 2: Figure 2 , Figure 3 and Figure 6 As shown, more specifically, a fixed seat 6 is provided for convenient adjustment of the lower mold 8. The positioning tube 4 can be moved along the guide rod 3. A return spring 13 is provided at the bottom of the positioning tube 4. One end of the return spring 13 is fixedly connected to the end face of the positioning tube 4, and the other end of the return spring 13 is fixedly connected to the surface of the placement groove 2. One end of the positioning tube 4 is inserted into the positioning groove 7. The first bearing 10 is fixedly connected to the side of the mounting plate 9. The support rod 11 is fixedly connected to the inner ring surface of the first bearing 10. A limit block 20 is provided on the surface of the support rod 11. The limit block 20 has a square plate structure. A through hole 21 is opened on the side of the fixed seat 6. The support rod 11 and the limit block 20 cooperate with the through hole 21.

[0031] When adjusting the lower mold 8 during use, the positioning tube 4 can be pulled to disengage it from the positioning groove 7, allowing the fixed seat 6 to rotate with the aid of the first bearing 10. The limiting block 20 prevents the fixed seat 6 from slipping on the support rod 11. The fixed seat 6 can then be fixed by the limiting nut 12 screwed to one end of the support rod 11. The rotation of the fixed seat 6 allows the lower mold 8 on different surfaces to cooperate with the press body 1. The return spring 13 can conveniently limit the positioning tube 4 and automatically reset it after pressing the positioning tube 4.

[0032] Example 3: Figure 1 , Figure 4 and Figure 5 As shown, more specifically, to facilitate the removal of the mounting plate 9, a traction wheel 19 is provided. A sliding groove 14 is provided on the side of the placement groove 2. The sliding groove 14 is a "T"-shaped plate structure. The mounting plate 9 is inserted into the sliding groove 14. A positioning plate 15 is provided on the side of the mounting plate 9. The positioning plate 15 is fixedly connected to the side of the press body 1 by limit bolts. A traction frame 16 is provided on the side of the mounting plate 9. A moving groove 17 is provided at the bottom of the mounting plate 9. A rotating rod 18 is provided on the side of the moving groove 17. A traction wheel 19 is sleeved on the surface of the rotating rod 18. The surface of the traction wheel 19 contacts the bottom of the sliding groove 14. Multiple sets of traction wheels 19 are provided. The multiple sets of traction wheels 19 are arranged linearly at equal intervals on the side of the moving groove 17.

[0033] First, the limiting bolts inside the positioning plate 15 can be removed. Then, the traction frame 16 can be pulled to disengage the mounting plate 9 from the slide groove 14, making it easy to remove the mounting plate 9. The rolling of the traction wheel 19 can reduce the friction between the mounting plate 9 and the slide groove 14, making it easier for workers to remove the mounting plate 9. The cooperation between the traction wheel 19 and the slide groove 14 can prevent the mounting plate 9 from disengaging from the side of the slide groove 14.
