Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a multi-stamping die for a car body bracket, including an upper die 1 and a lower die 2. A stamping plate 3 is installed on the bottom surface of the upper die 1, and a positioning frame 4 is fixed on the top surface of the lower die 2. A template 10 is fixed to the inner side of the positioning frame 4 with bolts. Several ventilation holes 9 are symmetrically opened on the inner wall of the positioning frame 4. The front and rear sides of the positioning frame 4 protrude outwards, and a fan 11 is fixed at the protrusion. Several water guide columns 7 are evenly arranged on the top of the positioning frame 4. The ends of the water guide columns 7 extend to the inner side of the positioning frame 4, and the positions of the water guide columns 7 correspond to the positions of the ventilation holes 9. Liquid chamber 17 and liquid chamber 20 are opened on both sides of the interior of the lower die 2. The ends of the water guide columns 7 on both sides are connected to connecting pipes 14, and the ends of the two connecting pipes 14 extend into liquid chamber 17 and liquid chamber 20, respectively. The template 10 and the workpiece on the template 10 are cooled by air cooling to ensure the stamping quality.

[0022] Further improvements include a groove 13 on the bottom surface of the lower mold 2, with several heat sinks 12 vertically and equidistantly installed inside the groove 13, and water pipes 18 horizontally installed on both sides inside the groove 13. The water pipes 18 pass through the heat sinks 12 and extend to the liquid chamber 17 and the liquid chamber 20 at both ends, respectively. The heat sinks 12 cool the cooling liquid flowing in the water pipes 18.

[0023] Further improvements include the placement frame 4 having several upper water guide plates 8 at its top, with both ends of the upper water guide plates 8 connected to the upper ends of the water guide columns 7. The placement frame 4 also has several lower water guide plates 16 inside, with both ends of the lower water guide plates 16 connected to the lower ends of the water guide columns 7. The upper water guide plates 8 and lower water guide plates 16 are alternately arranged. The cooling liquid in the second liquid chamber 20 is pumped out by the pump 19 and then discharged to the other side through the water guide column 7, the upper water guide plate 8, and the lower water guide plate 16 on one side, entering the first liquid chamber 17. It then returns to the second liquid chamber 20 through the water guide pipe 18 to form a circulation of the cooling liquid.

[0024] In a further improvement, a pump 19 is installed inside the second liquid chamber 20. The liquid output end of the pump 19 is connected to the end of the connecting pipe 14 inside the second liquid chamber 20, and the pump 19 drives the liquid flow inside the liquid chamber.

[0025] Further improvements include the installation of a heat sink 15 on the surface of the water guide column 7 and inside the positioning frame 4. The heat sink 15 contacts the incoming air to cool it down and ensure heat dissipation quality.

[0026] Further improvements include a positioning post 6 vertically installed at the bottom corner of the upper mold 1, and a positioning tube 5 vertically fixed at the top corner of the lower mold 2. The positioning tube 5 and the positioning post 6 work together to position the upper mold 1 and the lower mold 2.

[0027] Working principle: The template 10 is fixed inside the positioning frame 4, and the workpiece is fixed on the template 10. Then, the upper mold 1 is driven by the power device to press the lower mold 2. The stamping plate 3 presses the workpiece on the template 10. After the stamping is completed, the workpiece can be removed. After the fan 11 and pump 19 are turned on, the fan 11 blows the outside air into the positioning frame 4 through the ventilation hole 9 to cool the workpiece and template 10. When the cooled air enters the inside of the positioning frame 4, it comes into contact with the water guide column 7 and the heat sink 15 on the surface of the water guide column 7 to cool the air and improve the cooling effect. After the pump 19 is started, it drives the liquid in the liquid chamber 20 into the water guide column 7. After passing through the water guide column 7, it enters the liquid chamber 17 and is sent back to the liquid chamber 20 by the water guide pipe 18. When passing through the water guide pipe 18, the heat sink 12 cools the water guide pipe 18 to ensure the heat dissipation effect.

The problem solved by this utility model is that in existing multi-stamping dies for car body brackets, during material extrusion, the mold and material... The mutual friction generates a large amount of heat, which needs to be dissipated in time, otherwise it will reduce the service life of the mold. When the heat is high, it will also affect the processed material, causing the material to deform due to heat and affecting the quality of the product. This utility model, through the combination of the above-mentioned components, installs a fan 11 on the outside of the positioning frame 4 of the lower mold 2. The fan 11 sends the outside air into the template 10 on the inside of the positioning frame 4 through the ventilation hole 9, which can quickly cool down the template 10 and the car bracket supported on the template 10, reduce the temperature of the bracket body after multiple stampings. A water guide column 7 is set on the inside of the positioning frame 4 to cool the incoming air, ensure the heat dissipation effect, and improve the quality of the stamped product.
