[0043] In this embodiment, the combined blowing and suction design of the three-chamber air collection box achieves efficient dust removal, avoids secondary dust re-entrainment, and solves the problems of inaccurate and inefficient manual operation in the prior art.

[0044] Furthermore, such as Figure 1 , 2 As shown in Figure 3, in order to achieve the integration of dust removal and lubrication and improve the mold life and product surface quality, an oil collection box (11) is provided on the outside of the third gas collection chamber (613) of the gas collection box (61);

[0045] The oil collection tank (11) is provided with an oil collection chamber (111), and a number of oil nozzles (112) are provided on the upper and lower surfaces of the oil collection chamber (111), and an oil inlet connector (113) is provided at the rear end.

[0046] Furthermore, such as Figure 1 , 2 As shown in Figure 3, in order to enhance the physical dust removal effect and remove stubborn impurities, a brush (13) is provided on the lower side of the gas collecting box (61) near the first gas collecting chamber (611).

[0047] Furthermore, such as Figure 1 , 2 As shown in Figure 3, in order to improve the ease of maintenance and service life of the device, the brush (13) is fixed to the gas collection box (61) by a detachable connection.

[0048] Furthermore, such as Figure 1 , 2 As shown in Figure 3, in order to ensure that the dust removal mechanism moves smoothly and is positioned accurately, and to enhance its reliability, the left and right drive mechanism (5) is a screw slide module.

[0049] Furthermore, such as Figure 1 , 2 As shown in Figure 3, in order to achieve automated operation of the entire device, reduce manual intervention, and improve operational accuracy and efficiency, a PLC control system is also included.

[0054] Working principle:

[0055] Under the control of the PLC control system, when the stamping machine opens the mold, the left and right drive mechanisms 5 activate, driving the dust removal mechanism 6 to move from the left side of the mold to the right side. Simultaneously, the second solenoid valve 60 opens, and the compressed air source 9 supplies air to the second air collection chamber 612, blowing and cleaning the cavities of the upper mold 1 and lower mold 2 through the air blowing hole 30. At the same time, the first solenoid valve 50 opens, and the exhaust pump 7 starts, creating negative pressure in the first air collection chamber 611 and the third air collection chamber 613, drawing in flying dust through the suction hole 10. After dust removal, during the return process, the third solenoid valve 80 opens, and the stamping oil in the oil tank 12 is evenly sprayed onto the cavity through the oil nozzle 112. The brush 13 assists in brushing away stubborn impurities during its movement. The entire process is fully automatic, requiring no manual intervention.
