A cooling component is fixedly installed on the outer wall of the second mounting block 3, and the cooling component is used to reduce the high temperature generated by grinding during grinding. A supporting component is installed inside the first mounting block 2, and the supporting component is used to stably support the device on the inner wall of the mold when in use.

[0024] When in use, the device is supported on the inner wall of the mold through the supporting assembly, and then the driving motor 4 is turned on to drive the rotating block 5 to rotate, and then the first connecting rod 6 is driven to rotate by the rotating block 5, and then the grinding block 7 is driven to rotate, so that the inner wall of the mold can be grinded, and the device is pushed to move the grinding position through the push rod 1. During grinding, the cooling assembly is turned on to reduce the high temperature generated by grinding.

[0025] Specifically, the cooling component includes a first water channel 101, a water pipe 10, a second water channel 1001, an annular water outlet block 11, and a nozzle 12. The outer wall of the second mounting block 3 is fixedly mounted with an annular water outlet block 11, and the top of the annular water outlet block 11 is fixedly connected with a plurality of nozzles 12 distributed in an annular shape. The outer wall of the push rod 1 is fixedly connected with the water pipe 10, and the top of the water pipe 10 is fixedly connected to the bottom of the annular water outlet block 11. The push rod 1 has a first water channel 101 opened inside, and the water pipe 10 has a second water channel 1001 opened inside, and the first water channel 101 and the second water channel 1001 are connected to each other.

[0026] When in use, water flows into the second water channel 1001 through the first water channel 101, and then is sprayed out from the nozzle 12 through the annular water outlet block 11. The water will be sprayed on the inner wall of the mold, which can play a role in cooling.

[0027] The support assembly includes a first mounting groove 201, a first spring 202, a second connecting rod 8, a support wheel 9 and an anti-slip groove 901. The first mounting groove 201 is opened inside the first mounting block 2, and two symmetrically distributed second connecting rods 8 are movably installed inside the first mounting groove 201. Two first springs 202 are fixedly installed inside the first mounting groove 201. The first spring 202 is located between the two second connecting rods 8. A support wheel 9 is movably installed on one end of the second connecting rod 8 away from the first spring 202, and an anti-slip groove 901 is opened on the outer wall of the support wheel 9.

[0028] When in use, the device is placed inside the mold, and the elastic force of the first spring 202 pushes the second connecting rods 8 at both ends, while driving the support wheels 9 to fit tightly against the inner wall of the mold, thereby playing a supporting role; when the device moves, the support wheels 9 rotate with the movement, and the anti-skid groove 901 can prevent the support wheels 9 from slipping.

[0029] Four second mounting grooves 501 distributed in an annular shape are formed inside the rotating block 5 . The first connecting rod 6 is located inside the second mounting groove 501 . A second spring 502 is fixedly installed inside the second mounting groove 501 . The second spring 502 is located at the rear end of the first connecting rod 6 .

[0030] When in use, the elastic force of the second spring 502 pushes the first connecting rod 6 and drives the grinding block 7 to stick to the inner wall of the mold. The second spring 502 can be used to grind molds of different models and different inner diameters.

[0031] One end of the first connecting rod 6 away from the second spring 502 is fixedly connected to a fixing block 601 , and the grinding block 7 is bolted to the outer wall of the fixing block 601 .

[0032] During use, when the grinding block 7 needs to be replaced, the bolts need only be removed and then replaced.

[0033] A clamping groove 301 is formed on the top of the second mounting block 3 , and a clamping ring 503 is fixedly connected to the bottom of the rotating block 5 . The clamping ring 503 is located inside the clamping groove 301 .

[0034] When in use, the rotating block 5 can be fixed on the top of the second mounting block 3 through the cooperation of the slot 301 and the snap ring 503, while not affecting the rotation of the rotating block 5, preventing the rotating block 5 from falling off the driving motor 4 due to high-speed rotation.

[0035] Working principle:

[0036] First, place the device on the inner wall of the mold, and use the elastic force of the first spring 202 to push the second connecting rods 8 at both ends, while driving the supporting wheels 9 to stick to the inner wall of the mold, which can play a supporting role. At the same time, the elastic force of the second spring 502 pushes the first connecting rod 6, while driving the grinding block 7 to stick to the inner wall of the mold, so that the grinding block 7 can fit the inner walls of molds of different models and different inner diameters, thereby improving the grinding efficiency.

[0037] Next, the device is pushed to move the grinding position by the push rod 1, and then the driving motor 4 is turned on to drive the rotating block 5 to rotate. When the rotating block 5 rotates, the grinding block 7 is driven to rotate by the first connecting rod 6, so that the inner wall of the mold can be ground.

[0038] During polishing, water flows into the second water channel 1001 through the first water channel 101, and then is sprayed out from the nozzle 12 through the annular water outlet block 11. The water will be sprayed on the inner wall of the mold, which can play a role in cooling.
