[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the implementation mode and the accompanying drawings. Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model.

[0019] Reference Figure 1 and Figure 2 A pneumatic mud compressor includes a cylinder assembly 3, a compressor main assembly 2 and a gas transmission assembly 1. The gas transmission assembly 1 includes a gas tank 11. A booster valve 12 and a control valve 13 are installed on the gas tank 11. The gas source is pressurized by the booster valve 12 and then stored in the gas tank 11. The control valve 13 is connected to an air inlet pipe 14 and an air return pipe 15.

[0020] Reference Figure 1 , Figure 3 and Figure 4 The cylinder assembly 3 includes a cylinder 31 and a piston assembly 32 fixed to the top of the piston rod of the cylinder 31. The air inlet pipe 14 is connected to the air inlet port of the cylinder 31, and the air return pipe 15 is connected to the air outlet port of the cylinder 31. The air inlet port and the air outlet port are both equipped with a pressure regulating valve 33. A magnetic switch 34 is installed on the cylinder 31.

[0021] The compressor main body assembly 2 includes a tank body 21 and a base 22 fixed to the bottom of the tank body 21. A press-fit plate 23 is fixed to the bottom of the tank body 21. The press-fit plate 23 is fixed to the base 22 by bolts. A connecting pipe 231 is fixed to the bottom of the press-fit plate 23. The connecting pipe 231 extends from the base 22. The mud is sucked into the tank body 21 through the connecting pipe 231.

[0022] The four corners below the base 22 are all equipped with height-adjustable column feet (not shown in the figure), which can effectively prevent corrosion and facilitate installation and fixing. The column feet include a first column foot and a second column foot, the first column foot is located above the second column foot, the first column foot is fixed to the base 22, a connection hole is opened at the bottom of the first column foot, and the top of the second column foot is inserted into the connection hole and threadedly connected to the connection hole.

[0023] The cylinder 31 is located above the tank body 21. A first mounting plate 4 is fixed to the side of the cylinder 31 close to the tank body 21. A second mounting plate 5 is fixed to the side of the tank body 21 close to the cylinder 31. The first mounting plate 4 and the second mounting plate 5 are fixed by bolts and nuts. Under the action of the cylinder 31, the piston assembly 32 can reciprocate in the tank body 21.

[0024] The implementation principle of the pneumatic mud compressor of the utility model is as follows: the gas source is supplied to the gas transmission component 1, and the gas is pressurized by the booster valve 12 and stored in the gas tank 11. The control valve 13 receives a signal, and the gas in the gas tank 11 is delivered to the cylinder 31, driving the cylinder 31 to reciprocate.

[0025] The piston assembly 32 of the cylinder 31 is initially extended, and the cylinder 31 receives a signal to retract, driving the piston assembly 32 to move together, and the mud is sucked into the tank body 21 through the press plate 23. After the cylinder 31 is retracted to its position, the magnetic switch 34 receives a signal, the control valve 13 receives a signal, the cylinder 31 stops moving, and the mud is sucked.

[0026] After the molding machine has finished low injection, the control valve 13 receives a signal, controls the cylinder 31 to slowly extend, and the cylinder 31 drives the piston assembly 32 to pressurize the mud in the tank 21, and injects the mud into the molding machine through the mold pressing plate 23. When the pressure reaches the required level, adjust the pressure regulating valve 33 to stop the cylinder 31 from pressing down and start to maintain the pressure.

[0027] When the molding machine finishes high injection and is ready to release pressure and open the mold, the control valve 13 receives a signal to control the cylinder 31 to slowly retract, suck the mud again, and then repeat the above action.

[0028] The pneumatic mud pressurizer of the utility model has low cost, small space occupation, low requirements for accessories, and simpler structure and control. The mud is pressurized by the cylinder 31. Compared with the diaphragm pump device, the mud pressure rises more slowly and no bubbles are generated inside the model frame, thereby improving the qualified rate of the blank product. Adding an adjustable column foot under the base 22 of the pressurizer main body assembly can effectively prevent corrosion and facilitate installation and fixation. Adding a pressure regulating valve 33 in the assembly of the gas tank 11 can adjust the air intake pressure of the cylinder 31 and thus adjust the output force of the cylinder 31.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
