The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Embodiment 1:

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A mold repair device for silica sol precision casting includes a base 1, and also includes: a clamping component rotatably connected to the base 1, wherein the clamping component is used to clamp and fix the mold to be polished and repaired; a moving seat 3, connected to the base 1; a sleeve 301, fixedly connected to the moving seat 3, wherein a piston disc 302 is slidably connected in the sleeve 301, a spring 303 is fixedly connected between the piston disc 302 and the inner wall of the sleeve 301, and a spring 303 is fixed on the piston disc 302. A connecting rod 304 is connected, and one end of the connecting rod 304 passing through the sleeve 301 is fixedly connected to the hollow column 5, the sleeve 301 is fixedly connected to the hollow column 5 through a pressure relief pipe 502, a high-pressure air nozzle 501 is fixedly connected to the hollow column 5, and a pressure relief valve is arranged on the pressure relief pipe 502; a booster pump 503 is fixedly installed on the base 1, wherein the booster pump 503 is fixedly connected to the sleeve 301 through a pipe 504; a grinding component is arranged on one end of the connecting rod 304 passing through the sleeve 301.

[0025] The clamping component comprises a connection block 201 symmetrically connected to the base 1 , a plurality of cylinders 202 are fixedly connected to the connection block 201 at equal intervals, and a fixing block 203 is fixedly connected to the output end of the cylinder 202 .

[0026] It also includes an electric telescopic rod 2 connected to the base 1 , and a connecting block 201 is fixedly connected to an output end of the electric telescopic rod 2 .

[0027] It also includes a rotating shaft 101 rotatably connected to the base 1, the electric telescopic rod 2 is fixedly connected to one end of the rotating shaft 101 through a mounting base, the base 1 is fixedly connected to a motor 102, the output end of the motor 102 and the rotating shaft 101 are fixedly connected to pulleys, and the two pulleys are connected by a belt 103.

[0028] The grinding component includes a connecting sleeve 4 and a plug-in block 401 plugged into the connecting sleeve 4 , a grinding block 402 is fixedly connected to the plug-in block 401 , and the plug-in block 401 is fixedly connected to the connecting sleeve 4 via a fixing bolt 403 .

[0029] When the repaired wax model needs to be polished, the wax model is first placed between the two clamping parts, and then the electric telescopic rod 2 is started, which pushes the two clamping parts to move toward each other until the two clamping parts are respectively moved to the two ends of the wax model, and then the cylinder 202 is started, and the cylinder 202 pushes the fixed block 203 to move to the side close to the inner wall of the wax model until the fixed block 203 is tightly against the inner wall of the wax model, thereby achieving the purpose of limiting and fixing the wax model, and then the booster pump 503 is started, and the booster pump 503 is pumped into the sleeve 301 through the pipeline 504. The gas is delivered, and a one-way valve is provided on the pipeline 504 to increase the pressure in the sleeve 301, and then the gas pressurized in the sleeve 301 pushes the piston plate 302 to slide to the side away from the pipeline 504 and compresses the spring 303. At the same time, the piston plate 302 pushes the grinding component to move to the side close to the wax model through the connecting rod 304 until the grinding block 402 of the grinding component abuts against the outer surface of the wax model, and then the motor 102 is started, and the motor 102 drives the rotating shaft 101 through the belt 103 to drive the wax model to rotate, so as to grind and polish the outer surface of the wax model;

[0030] At the same time, in the process of grinding and polishing the outer surface of the wax model, when the air pressure continuously increased by the booster pump 503 into the sleeve 301 is greater than the pressure relief value set by the pressure relief valve on the pressure relief pipe 502, the pressure relief valve automatically opens to release the pressure, so that the excess gas continuously pressurized into the sleeve 301 is discharged from the sleeve 301 through the pressure relief pipe 502, thereby maintaining the internal pressure of the sleeve 301 constant, thereby ensuring that the force of the grinding block 402 on the surface of the wax model is always consistent, thereby helping the grinding block 402 to better grind and polish the surface of the wax model;

[0031] At the same time, the gas discharged from the sleeve 301 through the pressure relief pipe 502 is transported into the high-pressure jet nozzle 501 through the pressure relief pipe 502 and the hollow column 5 in turn and sprayed out, thereby cleaning the debris remaining on the surface of the wax model, thereby ensuring the cleanliness of the polishing area of ​​the wax model surface, thereby improving the effect of the polishing block 402 on the outer surface of the wax model.

[0032] It should be noted that, since the distance between the two clamping parts can be adjusted by the electric telescopic rod 2, the distance between the two clamping parts can be adjusted according to the size of the wax mold to be polished, so that it is suitable for clamping and fixing wax molds of different sizes;

[0033] The pipe 504 and the pressure relief pipe 502 are both made of stretchable and shrinkable hoses, so the pipe 504 will not interfere with the left and right reciprocating movement of the movable seat 3, and the pressure relief pipe 502 will not interfere with the movement of the grinding parts.

[0036] When it is necessary to grind and polish different positions of the wax model, the staff can also drive the screw 6 to rotate through the handle 602, and the screw 6 drives the movable seat 3 to move left or right on the guide rod 601. At the same time, the movable seat 3 drives the grinding component to move synchronously, so that the position of the grinding component can be adjusted according to the needs, and then the grinding component is convenient for grinding and polishing different positions of the wax model, thereby improving the practicality of the repair device.

[0037] Embodiment 3:
