[0018] The following will describe the present utility model in detail with reference to the accompanying drawings.

[0019] Refer to Figure 1 , a forming die for an automotive air-conditioning compressor housing, including a lower die base 1, a lower punch 2 fixedly installed on the lower die base 1, an upper die base 3, and an upper die cavity 4 fixedly installed on the upper die base 3. The lower die base 1 is fixedly provided with a first annular platform 5 outside the lower punch 2. A plurality of springs 6 are vertically fixed on the first annular platform 5. The upper ends of the plurality of springs 6 are fixedly abutted against a second annular platform 7. A plurality of limiting rods 8 spaced from the springs 6 are fixedly provided on the first annular platform 5. An installation platform 9 is fixedly provided on the lower die base 1. A driving wheel and a driven wheel (not shown in the figure) are rotatably connected to the installation platform 9 through bearings. A transmission belt 10 is sleeved between the driving wheel and the driven wheel, and a driving motor for driving the driving wheel to rotate is fixedly provided on the installation platform 9. A plurality of blanking rods 11 are fixedly arranged at equal intervals on the transmission belt 10. The movement of the blanking rods 11 driven by the driving motor is matched with the movement of the upper die base.

[0020] The upper ends of the limiting rods 8 penetrate upward through the second annular platform 7. A relief groove 12 for inserting the limiting rods 8 is opened on the upper die base 3. The lifting movement of the second annular platform 7 is limited by the limiting rods 8 to prevent it from shifting and ensure the stability of the structure. And a chamfer 13 is provided at the lower end of the relief groove 12 to facilitate the smooth insertion of the limiting rods 8 into the relief groove 12, so that the upper die cavity 4 can continue to descend after contacting the second annular platform 7.

[0021] A buffer pad 14 is provided on the lower die base 1. The buffer pad 14 is adhesively bonded in a ring shape outside the limiting rods 8. After the upper die base 3 descends in place, it contacts the buffer pad 14, which can absorb part of the impact force, avoid direct collision between the upper die base 3 and the lower die base 1, effectively reduce the vibration and noise caused by the impact, and protect the accuracy and service life of the die.

[0022] A receiving groove 15 is opened on the lower die base 1. One end of the spring 6 is fixed on the inner bottom wall of the receiving groove 15. By providing the receiving groove 15 to accommodate part of the spring 6, part of the space is saved, making the whole device more compact.

[0023] Fixed rods 16 are fixedly arranged at the four corners of the lower die base 1, and a fixed sleeve 17 which is in guiding cooperation with the fixed rod 16 is fixedly arranged at the bottom of the upper die base 3, so that the upper groove keeps in alignment with the lower punch 2 during the up-and-down reciprocating movement, ensuring the forming effect.

[0024] Working principle: When the mold is installed on the machine body for use, first place the workpiece on the lower punch 2, and the upper die base 3 drives the upper female die 4 to move downward to stamp and form it. During this process, when the upper female die 4 moves downward, it will push the second annular platform 7 downward, and the spring 6 is compressed. After the upper female die 4 moves downward in place, the stamping is completed. Then the upper female die 4 moves upward, and the second annular platform 7 moves upward under the reset action of the spring 6 and pushes the formed shell upward. The shell disengages from the lower punch 2 and is placed on the surface of the second annular platform 7. Then the drive motor drives the transmission belt 10 to drive, driving the blanking rod 11 to move to push the shell on the second annular platform 7 away between the upper female die 4 and the lower punch 2, thus realizing the rapid blanking after the shell is formed.

[0025] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
