[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a circulating static pressure box for a casting machine, comprising a box body 1, an air outlet 2 is provided at the bottom of the box body 1, a partition 3 is fixedly installed on the inner wall of the box body 1, and three groups of partitions 3 are provided. The three groups of partitions 3 divide the interior of the box body 1 into four groups of cavities, an air duct 4 is fixedly installed on the top of the box body 1, and four groups of air ducts 4 are provided. The four groups of air ducts 4 are respectively connected to the four groups of cavities inside the box body 1, and a connecting frame 5 is fixedly installed at one end of the air duct 4 away from the box body 1. A filter screen 6 is fixedly installed on the inner wall of the connecting frame 5, and the filter screen 6 can be used to The wind entering the air duct 4 is filtered to prevent impurities from entering the interior of the box 1. The box 1 is provided with an adjustment mechanism 7 for adjusting the spray angle. By setting the adjustment mechanism 7, the wind direction sprayed from the air nozzle 2 can be adjusted, so that the spray angle of the static pressure box can be more flexible, so that the spray angle can be freely adjusted according to different usage environments. The box 1 is provided with a cleaning mechanism 8 for cleaning the filter 6. By setting the cleaning mechanism 8, impurities on the surface of the filter 6 can be cleaned to prevent impurities from adhering to the surface of the filter 6 and affecting the air intake effect of the air duct 4.

[0024] The above-mentioned adjusting mechanism 7 includes guide plate 71, sliding frame 72, L rod 73, limiting slot 74, and electric push rod 75; guide plate 71 is hinged to the bottom of box body 1, and guide plate 71 can be adjusted by rotating guide plate 71. At this time, guide plate 71 can be used to guide the wind sprayed from air outlet 2, so that the wind direction sprayed from air outlet 2 can be adjusted. The side wall of guide plate 71 is provided with limiting slot 74, and the sliding frame 72 is slidably connected to the outer wall of box body 1, and electric push rod 75 is fixedly installed on the outer wall of box body 1. The piston end of electric push rod 75 is fixedly mounted on the side wall of sliding frame 72. One end of L rod 73 is fixedly mounted on the bottom of sliding frame 72, and the other end of L rod 73 is attached to the inner wall of limiting slot 74, and the sliding frame 72 drives L rod 73 to move. At the same time, L rod 73 will fit the inner wall of limiting slot 74 and move to push guide plate 71, so that guide plate 71 rotates at the bottom of box body 1

[0025] The above-mentioned cleaning mechanism 8 includes a scraper 81, an inclined rod 82, and a guide rod 83; the scraper 81 is slidably connected to the inner wall of the connecting frame 5, and the scraper 81 is attached to the outer wall of the filter 6. The sliding of the scraper 81 can scrape off impurities on the surface of the filter 6 to prevent impurities from adhering to the surface of the filter 6 and affecting the air intake effect of the air duct 4. The top of the sliding frame 72 is fixedly installed with an inclined rod 82, and the bottom of the scraper 81 is fixedly installed with a guide rod 83. The end of the guide rod 83 away from the scraper 81 passes through the connecting frame 5 and is attached to the inner wall of the inclined rod 82.
