[0049] The working principle and use process of this utility model:

[0050] First, the operator places the mold to be processed between the two clamping blocks 8, and then starts the No. 1 pneumatic cylinder 4. As the No. 1 pneumatic cylinder 4 runs, the moving block 5 and the driving rod 6 will move to the left along the inner surface of the limit frame 3 driven by the No. 1 pneumatic cylinder 4.

Finally, the two clamping blocks 8 will contact the left and right ends of the mold to be processed and clamp the mold, thereby ensuring the stability of the mold during the processing and ensuring the accuracy of the grinding process.

[0051] When the operator needs to replace the grinding disc 23, the operator moves the two paddles 26 to make the two locking blocks 25 start to move toward each other along the outer surface of the limit rod 28, which makes the two locking blocks 25 gradually separate from the inner surfaces of the two connecting blocks 24. Finally, when the two locking blocks 25 no longer come into contact with the two connecting blocks 24, the cooperation between the connecting blocks 24 and the locking blocks 25 will be released, so that the grinding disc 23 and the connecting blocks 24 lose the fixation from the locking blocks 25. At this time, the operator can directly remove the grinding disc 23 as a whole and replace it, which effectively improves the speed of replacing the grinding disc 23 and reduces the physical exertion of the operator.
