There are two sets of air guides 703, with two air guides in each set. The lower end of the air guide 703 is fixedly connected to the slide rod 701. A discharge port 704 is provided on one side of the slide rod 701 through the lower mold 5. The discharge port 704 is used to connect the lower mold 5 to the collection box 601.

[0027] The demolding assembly 8 includes a movable plate 801. There are two sets of movable plates 801. Every four movable plates 801 form a ring, and each set of movable plates 801 consists of five rings of movable plates 801. The movable plates 801 are slidably connected to the lower mold 5. A second spring 802 is provided in the middle of the movable plate 801. The lower end of the second spring 802 is fixedly connected to the lower mold 5.

[0028] The upper end of the second spring 802 is fixedly provided with a support plate 803. There are two support plates 803. The four sides of the support plate 803 are slidably connected to the lower mold 5. The lower end of the support plate 803 is fixedly connected to the movable plate 801. The two sides of the support plate 803 are provided with slots 804.

[0029] A spring 805 is fixedly installed on one side of the pallet 803 inside the lower mold 5. A stop block 806 is fixedly installed on the side of the spring 805 near the pallet 803. The stop block 806 is slidably connected to the lower mold 5.

[0030] The working principle and usage process of this invention: During the stamping operation, when the upper die 3 and the lower die 5 are closed, First: The telescopic rod 603 retracts. When the telescopic rod 603 is fully retracted, it can drive the pressure plate 602 to move down. When the pressure plate 602 moves down, the iron filings in the collection box 601 can be compacted by the force of the punch press itself. Second: The upper mold 3 continues to move down, which can press down the air guide 703. At this time, the external vacuum pump is still continuously evacuating the lower mold 5. This allows the iron filings remaining on the inner wall of the upper mold 3 to be sucked away by the large pressure difference after the upper mold 3 moves up. Finally: After the upper mold 3 is fully pressed down, the support plate 803 can be fully pressed down and a punching is completed. At this time, the stops 806 on both sides of the support plate 803 enter the slot 804 under the action of the spring 805. The stops 806 can temporarily lock the support plate 803. When the upper mold 3 moves upward: First, the air vent 703 is released, and the air vent 703 can be reset under the action of the spring piece 702. At this time, because the air pressure behind the air vent 703 is low, the air in front of the air vent 703 will instantly enter the air vent 703 and eventually be transported to the collection box 601. In this process, the iron filings remaining on the inner wall of the upper mold 3 can be removed. Second, as the upper mold 3 continues to move upward, the telescopic rod 603 is gradually stretched. When the telescopic rod 603 is fully pulled out, it can drive the pressure plate 602 to move upward and reset, waiting for the next downward press. It should be noted that when the upper mold 3 releases the air vent 703, it will also lose pressure on the pallet 803. The pallet 803 can then return to its original position under the action of the second spring 802. However, the lower edge of the stop blocks 806 on both sides of the pallet 803 has a small inclination, so the pallet 803 cannot descend as quickly as when it is pressed down. At this time, the second spring 802 under the pallet 803 is in the state of storing energy for bagging. As the pallet 803 slowly withdraws the stop blocks 806 completely, the pallet 803 can quickly return to its original position under the action of the second spring 802. At this time, the upward movement of the pallet 803 can assist in demolding the workpiece and scrape off the iron filings on the surface of the lower mold 5. When the pallet 803 quickly returns to the fixed point, it can also bounce the iron filings adhering to the pallet 803 upward. At this time, the air vents 703 on both sides can collect the scattered iron filings. When the iron filings in the collection box 601 accumulate to a certain extent, each press of the pressure plate 602 not only drives the iron filings downward, but also compacts the accumulated iron filings until the spring 608 can no longer bear the weight above. At this point, the upper mold 3 presses down to open the bottom plate 604, allowing the iron filings inside to be discharged in time.

[0031] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
