Detailed Implementation

[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 1-3 Fender reinforcement plate stamping die, including lower die base 1 and upper die base 2;

[0027] The lower mold core 3 is fixedly installed at the bottom of the lower mold base 1;

[0028] The lower mold core 3 is fixedly connected to the top of a third protrusion 10, the middle of which is higher than both ends of the third protrusion 10; the lower mold core 3 is fixedly connected to a fourth protrusion 11 symmetrically at the front and back of the right end of the third protrusion 10; the lower mold core 3 is fixedly connected to a second protrusion 6 symmetrically at the front and back of the left end of the third protrusion 10; the lower mold core 3 has a first groove 4 between the second protrusions 6.

[0029] The upper mold base 2 is fixedly connected to the bottom of the upper mold core 16. The bottom of the upper mold core 16 is provided with a fourth groove 9 that cooperates with the third protrusion 10. The upper mold core 16 is provided with a second groove 8 that cooperates with the fourth protrusion 11 symmetrically at the right end of the fourth groove 9. The upper mold core 16 is fixedly connected to the left end of the fourth groove 9 with a first protrusion 15 that cooperates with the first groove 4. The upper mold core 16 is provided with a fifth groove 19 that cooperates with the second protrusion 6 at the front and rear ends of the first protrusion 15.

[0030] The sheet metal is placed on the lower mold core 3, and the upper mold base 2 moves downward. The upper mold base 2 drives the upper mold core 16 to move downward. The fourth groove 9 and the third protrusion 10 cooperate to form the fishback-shaped hollow part of the fender reinforcement plate. The fourth protrusion 11 and the second groove 8 cooperate to form the mating groove opened between the fender reinforcement plate and other connecting parts. The first groove 4, the second protrusion 6, the first protrusion 15 and the fifth groove 19 cooperate to form the M-shaped slot for the fender reinforcement plate to engage with other connecting parts, so as to realize the rapid integrated molding of the fender reinforcement plate.

[0031] The lower mold base 1 is connected to limiting components for limiting the ends of the sheet metal at all four sides.

[0032] The limiting component includes a horizontal plate 12 and a vertical plate 7. The horizontal plate 12 is fixedly installed on the lower mold base 1. The horizontal plate 12 is fixedly connected to the vertical plate 7 near the lower mold core 3. The inner wall of the vertical plate 7 is in contact with the outer wall of the plate.

[0033] The straight plate with multiple sets of limiting components limits the front, rear, left, and right ends of the sheet metal to prevent slippage during stamping and ensure stamping quality.

[0034] The upper end of the inner wall of the straight plate 7 is provided with a slanted groove 5 for guiding the plate.

[0035] The inclined groove 5 facilitates the movement of the plate into the straight plate 7, making it easy to limit the movement.

[0036] The lower mold core 3 has a third groove 14, and the inner end of the horizontal plate 12 is inside the third groove 14.

[0037] The third groove 14 allows the straight plate 7 to be closer to the third protrusion 10, ensuring that the fender reinforcement plate can be stamped and formed, thus minimizing the size of the sheet metal between the straight plates 7 and saving materials.

[0038] The upper mold base 2 is connected to a guide assembly for guiding the movement of the upper mold base 2.

[0039] The guide assembly includes a wear-resistant block 13 and a guide seat 17. The guide seat 17 is symmetrically fixedly installed at the bottom of the left and right ends of the upper mold base 2. The lower mold base 1 has insertion slots 18 at both ends. The wear-resistant block 13 is fixedly installed on the inner wall of the upright part of the insertion slot 18.

[0040] The upper die holder 2 moves downward, and the wear-resistant block 13 in the insertion groove 18 guides the guide seat 17, thereby enabling the upper die holder 2 to be guided so that the upper die core 16 is directly opposite the lower die core 3 for stamping.

[0041] 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.
