[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A precision single-row six-axis cover plate shallow drawing tooling comprises a molding bottom die 1 and a stamping die 2. A coolant storage box 3 is fixed on the side of the molding bottom die 1. A cooling pipe 4 is fixed inside the coolant storage box 3. One end of the cooling pipe 4 is fixedly connected to an air intake pipe 5, and one end of the air intake pipe 5 extends to the outside of the coolant storage box 3. An exhaust component is arranged on the molding bottom die 1, and a cooling component is also arranged on the molding bottom die 1.

[0023] Reference Figure 3 The vacuum assembly includes a chamber 6, a sealing slide 7, a connecting rod 8, a return spring 9, two mounting tubes 10 and two one-way valves 11. The chamber 6 is opened inside the finalizing bottom mold 1. The sealing slide 7 is sealingly and slidably connected to the inner surface of the chamber 6. One end of the connecting rod 8 is fixedly connected to the sealing slide 7, and the other end of the connecting rod 8 extends to the outside of the chamber 6. One end of the return spring 9 is connected to the inner top surface of the chamber 6, and the other end is connected to the sealing slide 7. One end of the two mounting tubes 10 is connected to the chamber 6. The two one-way valves 11 are respectively installed on the two mounting tubes 10, and the other end of one of the mounting tubes 10 is connected to the cooling tube 4. When the sealing slide 7 moves downward, the sealing slide 7 can press the air in the chamber 6 into the cavity 12. Then, the gas will be sprayed into the mold cavity of the finalizing bottom mold 1 through a plurality of air outlet holes 13, which can cool the finalizing bottom mold 1 and the workpiece therein.

[0024] Reference Figure 4 The cooling component includes a cavity 12 and a plurality of air outlet holes 13. The cavity 12 is opened in the mold cavity of the shaping bottom mold 1. The plurality of air outlet holes 13 are all opened on the inner surface of the mold cavity of the shaping bottom mold 1, and the plurality of air outlet holes 13 are connected with the cavity 12. The cavity 12 is connected with the other end of another mounting tube 10. When the sealing slide plate 7 moves upward, the sealing slide plate 7 can extract air from the cooling tube 4, and the cooling tube 4 replenishes gas from the external environment through the air inlet pipe 5. The cooling tube 4 is immersed in the coolant, and the coolant can cool the gas flowing in the cooling tube 4, which makes the gas entering the chamber 6 have a lower temperature, thereby ensuring the cooling effect of the gas on the shaping bottom mold 1 and the workpiece therein.

[0025] Reference Figure 3The cooling tube 4 is in a spiral tubular structure, and the cooling tube 4 is made of aluminum alloy material. The cooling tube 4 is in a spiral tubular structure, which can extend the residence time of the airflow in the cooling tube 4 and extend the cooling time of the coolant for the gas. In addition, the cooling tube 4 is made of aluminum alloy material, and the aluminum alloy material has good thermal conductivity, which can further ensure the cooling effect of the coolant on the gas.

[0026] Reference Figure 3 The flow limiting directions of the two one-way valves 11 are opposite. Specifically, one of the one-way valves 11 limits the airflow to only enter the interior of the chamber 6 , and the other one-way valve 11 limits the airflow to only flow out of the chamber 6 .

[0027] Reference Figure 4 The plurality of air outlet holes 13 are evenly distributed in the mold cavity of the molding bottom mold 1, so that the cooling effect of the plurality of air outlet holes 13 on the molding bottom mold 1 and the workpiece can be ensured.

[0028] The specific working principle of the utility model is as follows:

[0029] When the precision single-row six-axis cover plate shallow drawing tooling proposed by the utility model is in use, when the stamping die 2 is located just above the shaping bottom die 1, the stamping die 2 does not contact the connecting rod 8. At this time, under the elastic force of the return spring 9, the sealing slide plate 7 is located at the upper end position of the chamber 6. When the shaping bottom die 1 and the stamping die 2 perform shallow drawing on the workpiece, the stamping die 2 moves downward. In this process, the stamping die 2 will squeeze the top of the connecting rod 8 and drive the connecting rod 8 to move downward. When the connecting rod 8 moves downward, it can drive the sealing slide plate 7 to move downward. When the shaping bottom die 1 and the stamping die 2 contact each other, the sealing slide plate 7 just moves to the lowest end position of the chamber 6. When the stamping die 2 is reset upward, the stamping die 2 no longer applies force to the connecting rod 8. At this time, the sealing slide plate 7 will be reset under the action of the return spring 9. Therefore, in the process of shallow drawing of the workpiece by the shaping bottom die 1 and the stamping die 2, the sealing slide plate 7 can be continuously The interior of the chamber 6 moves up and down. Since the flow limiting directions of the two one-way valves 11 are opposite, specifically, one of the one-way valves 11 limits the airflow to only enter the interior of the chamber 6, and the other one-way valve 11 limits the airflow to only flow out of the chamber 6. Therefore, when the sealing slide plate 7 moves downward, the sealing slide plate 7 can press the air in the chamber 6 into the cavity 12. Then, the gas will be sprayed into the mold cavity of the finalizing bottom mold 1 through a plurality of air outlet holes 13, which can cool the finalizing bottom mold 1 and the workpiece therein. When the sealing slide plate 7 moves upward, the sealing slide plate 7 can extract the air in the cooling pipe 4, and the cooling pipe 4 replenishes the gas from the external environment through the air inlet pipe 5. The cooling pipe 4 is immersed in the coolant, and the coolant can cool the gas flowing in the cooling pipe 4, which makes the gas entering the chamber 6 have a lower temperature, thereby ensuring the cooling effect of the gas on the finalizing bottom mold 1 and the workpiece therein;

[0030] The cooling tube 4 has a spiral tubular structure, which can extend the residence time of the airflow in the cooling tube 4 and extend the cooling time of the gas by the coolant. In addition, the cooling tube 4 is made of aluminum alloy material, which has good thermal conductivity, which can further ensure the cooling effect of the coolant on the gas.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
