[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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1: Please refer to the appendix of the instruction manual. Figure 1-5 A stamping die for forming spliced ​​parts, comprising a lower die base 1 and an upper die base 5;

[0027] The lower mold base 1 is fixedly connected to the top of the lower mold core 2;

[0028] The lower mold core 2 has a central groove 7 at the top; the lower mold core 2 has a first groove 8 on both the front and rear sides of the central groove 7; the lower mold core 2 has a second groove 9 at the right end of the central groove 7; the lower mold core 2 has a fourth protrusion 16 fixedly connected to the left end of the central groove 7, and the lower mold core 2 has a third groove 10 at the left end of the first groove 8.

[0029] The upper mold base 5 is fixedly connected to the upper mold core 6 at its bottom;

[0030] The upper mold core 6 has a central protrusion 14 fixedly connected to the bottom for use with the central groove 7. The upper mold core 6 has a third protrusion 15 fixedly connected to the front and rear sides of the central protrusion 14 for use with the first groove 8. The upper mold core 6 has a second protrusion 17 fixedly connected to the right end of the central protrusion 14 for use with the second groove 9. The upper mold core 6 has a fourth groove 12 opened at the left end of the central protrusion 14 for use with the fourth protrusion 16. The upper mold core 6 has a first protrusion 13 fixedly connected to the front and rear sides of the fourth groove 12 for use with the third groove 10.

[0031] The middle groove 7, the first groove 8, the middle protrusion 14 and the third protrusion 15 extrude the sheet into an M shape. At the same time, the third groove 10, the fourth protrusion 16, the fourth groove 12 and the first protrusion 13 extrude one end of the sheet into a raised state. The second protrusion 17 and the second groove 9 work together to extrude the other end of the sheet into a recessed state, which is conducive to the one-piece molding of the spliced ​​fender reinforcement plate.

[0032] The top of the lower mold base 1 is symmetrically and fixedly connected with guide structures for guiding the movement of the upper mold base 5, and the guide structures are fixedly connected to the upper mold base 5.

[0033] The guide structure includes a guide block 3 and a U-shaped sleeve 4. The guide block 3 is fixedly installed on the outer top of the lower mold base 1, and the U-shaped sleeve 4 is fixedly connected to the bottom of the upper mold base 5. The guide block 3 and the inner wall of the U-shaped sleeve 4 are in close contact and slidingly connected.

[0034] When the upper die base 5 moves downward, the upper die base 5 drives the U-shaped sleeve 4 of the guide structure to move downward. The guide block 3 guides the U-shaped sleeve 4, thereby guiding the upper die base 5 and thus guiding the upper die core 6, which is conducive to the upper die core 6 being stamped and formed directly opposite the lower die core 2.

[0035] The inner wall of the U-shaped sleeve 4 is fixedly connected with a wear-resistant block 11 for wear resistance.

[0036] The wear-resistant block 11 extends along the U-shaped sleeve 4 to extend its service life.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
