[0026] In the specific implementation process, it is particularly worth noting that when adjusting the size of the opening 87, the threaded block 83 drives the scale 881 to move. The scale 881 moves within the sealing ring 883, and the sealing ring 883 increases the sealing between the scale 881 and the empty box 7. The staff adjusts the size of the opening 87 by observing the position of the pointer 882 on the scale 881, thereby adjusting the discharge amount of the compressed gas;

[0027] Further, a cross plate 3 is installed at the bottom of the gas storage tank 4. The outer wall of the cross plate 3 is fixedly connected to one side of the mounting frame 1. A first air pipe 41 is connected to the top of the gas storage tank 4. When the valve on the first air pipe 41 is started, the compressed gas inside the gas storage tank 4 enters the first air pipe 41 at this time. The end of the first air pipe 41 is connected to the inner wall of the empty box 7 and then enters the empty box 7. A second air pipe 42 is connected to the inner wall of the empty box 7 and then enters the second air pipe 42 again, and finally enters the inside of the sand shooting cylinder 5. The end of the second air pipe 42 is connected to the inner wall of the sand shooting cylinder 5;

[0028] In the specific implementation process, it is particularly worth noting that when the valve on the first air pipe 41 is started, the compressed gas inside the gas storage tank 4 enters the first air pipe 41 at this time, then enters the empty box 7, enters the second air pipe 42 again, and finally enters the inside of the sand shooting cylinder 5. After completion, the valve on the first air pipe 41 is closed;

[0029] Further, a discharge pipe 52 is connected to the top of the sand shooting cylinder 5.

The top of the discharge pipe 52 is connected to the inner wall of the sand storage box 6. The molding sand is put into the inside of the sand storage box 6 through the feeding port at the top of the sand storage box 6. A spray head 51 is connected to the lower part of the sand cylinder 5. A vertical column 53 is fixedly connected between the mounting frame 1 and the sand shooting cylinder 5, and the vertical column 53 supports the sand shooting cylinder 5;

[0030] In the specific implementation process, it is particularly worth noting that the molding sand is put into the interior of the sand storage box 6 through the feeding port at the top of the sand storage box 6.

The threaded block 83 drives the first vertical plate 84 to descend. The first vertical plate 84 drives the slider 85 to slide in the chute on the inner wall of the second vertical plate 86. The first vertical plate 84 moves on the second vertical plate 86. The first vertical plate 84 descends to block the opening 87 to adjust the discharge amount of the compressed gas. After adjustment, the staff stops rotating the rotating block 81. The discharge amount of the compressed gas is adjusted according to different molding sands. After completion, the molding sand is put into the interior of the sand storage box 6 through the feeding port at the top of the sand storage box 6. The valve on the discharge pipe 52 is started. At this time, the molding sand inside the sand storage box 6 enters the interior of the sand injection cylinder 5 through the discharge pipe 52. After completion, the valve on the discharge pipe 52 is stopped. Then the valve on the first air pipe 41 is started. At this time, the compressed gas inside the gas storage tank 4 enters the first air pipe 41, then enters the empty box 7, enters the second air pipe 42 again, and finally enters the interior of the sand injection cylinder 5. At this time, the compressed gas drives the molding sand to be ejected from the nozzle 51 and sprayed into the sand box below.
