[0023] When the mold needs to be clamped and fixed, the electric telescopic rod 21 drives the clamping plate 22 fixedly connected to its telescopic end to move, and the movement of the clamping plate 22 drives the mold to move to the side of the fixed plate 23, and then the mold is clamped and fixed by the clamping plate 22 and the fixed plate 23. At this time, the second cylinder 19 drives the moving plate 2 fixedly connected to the telescopic end to move along the guide direction of the guide rod 17, so that the polishing head 16 contacts the mold surface;

[0024] As a further implementation of this embodiment, Figures 1 - 5 As shown, the bottom of the threaded block 13 is fixedly connected to a connecting plate 14, the bottom of the connecting plate 14 is fixedly connected to a third motor 15, the rotating end of the third motor 15 is fixedly connected to a rotating shaft 3, the bottom of the connecting column 26 is fixedly connected to a polishing head 16, and the third motor 15 drives the rotating shaft 3 and the polishing head 16 to rotate to polish the mold surface, the inside of the movable plate 2 is fixedly connected to a pair of guide columns 6, the outer sides of the two guide columns 6 are sleeved with movable blocks 7 movably connected thereto, the bottoms of the two movable blocks 7 are fixedly connected to support plates 8, the tops of the two support plates 8 are fixedly connected to a moving rod 11, one side of the movable plate 2 is fixedly connected to a first cylinder 9, and the extension and retraction of the first cylinder 9 is fixedly connected to the moving rod 11, one side of the moving rod 11 is fixedly connected to a second motor 10, and the second motor 10 and the moving rod 11 are fixedly connected, the inside of the moving rod 11 is movably connected to a screw rod 12, the outer side of the screw rod 12 is sleeved with a threaded block 13 threadedly connected thereto, and the threaded block 13 contacts the inner wall of the moving rod 11;

[0025] When the mold needs to be polished, the third motor 15 works to drive the rotating shaft 3 and the polishing head 16 fixedly connected to its rotating end to rotate. During the polishing process, the second motor 10 drives the lead screw 12 fixedly connected to its rotating end to rotate. The rotation of the lead screw 12 drives the threaded block 13 threadedly connected to it to move horizontally, thereby driving the lower polishing head 16 to move horizontally synchronously. At this time, the first cylinder 9 drives the moving rod 11 to move. The movement of the moving rod 11 drives the moving block 7 and the support plate 8 to move longitudinally along the guiding direction of the guiding column 6, thereby driving the lower polishing head 16 to move longitudinally synchronously;

[0026] As a further implementation manner of this embodiment, as Figures 1 - 5 shown, a pair of fixed columns 4 are fixedly connected to both sides of the rotating shaft 3. A moving column 5 is movably connected to the inside of each of the two fixed columns 4. An arc-shaped plate 25 is fixedly connected to the inner side of each of the two moving columns 5. A connecting column 26 is arranged inside the rotating shaft 3. Insertion blocks 27 inserted into the connecting column 26 are fixedly connected to the inner side of each of the two arc-shaped plates 25. Springs 28 are sleeved on the outer sides of the two moving columns 5 and are located between the inside of the fixed column 4 and the arc-shaped plate 25. Pulling plates 29 are fixedly connected to the opposite sides of the two moving columns 5. A pair of sliding grooves 30 are formed inside the rotating shaft 3.

The position of the connecting column 26 can be limited by the sliding grooves 30 and the sliders 31;

[0027] When the polishing head 16 needs to be replaced, the pulling plate 29 is pulled to drive the moving column 5 and the arc-shaped plate 25 fixedly connected to it to move. The movement of the arc-shaped plate 25 drives the insertion block 27 fixedly connected to it to be pulled out from the inside of the connecting column 26. At the same time, the movement of the arc-shaped plate 25 compresses the spring 28. Without the limit of the insertion block 27, the connecting column 26 slides out of the inside of the rotating shaft 3 by its own gravity, thereby replacing the polishing head 16. Then, by pulling the pulling plate 29, the insertion block 27 is pulled out of the inside of the rotating shaft 3. Then, the polishing head 16 to be replaced is inserted into the inside of the rotating shaft 3 through the sliding grooves 30 and the sliders 31. At this time, the pulling plate 29 is released.

[0028] Specific working principle:

[0029] When the mold needs to be polished, first place the mold to be polished inside the fixed groove 20. Then, operate through the electric telescopic rod 21. Driven by the electric telescopic rod 21, the pressing plate 22 on the front side squeezes and fixes the mold inside the fixed groove 20. Then, control the second cylinder 19 to drive the moving plate 2 to move downward to change the distance between the polishing head 16 and the mold. Then, the third motor 15 works to drive the polishing head 16 to rotate, and the polishing head 16 polishes the upper surface of the mold. During the polishing process, the second motor 10 drives the lead screw 12 to rotate. The rotation of the lead screw 12 drives the threaded block 13 to move horizontally, thereby driving the polishing head 16 below to move horizontally synchronously. Then, the first cylinder 9 drives the moving rod 11 to move. The movement of the moving rod 11 drives the moving block 7 and the support plate 8 to move longitudinally along the guiding direction of the guiding column 6, thereby driving the polishing head 16 below to move longitudinally synchronously, so as to achieve the purpose of comprehensive polishing. When the polishing head 16 needs to be replaced, pull the pull plate 29 to drive the arc plate 25 and the insertion block 27 to move. Without the limiting and fixing of the insertion block 27, the connecting column 26 slides out from the inside of the rotating shaft 3 by its own gravity. Then, pull the pull plate 29, and insert the polishing head 16 to be replaced into the inside of the rotating shaft 3 through the sliding groove 30 and the sliding block 31. Release the pull plate 29, and the arc plate 25 and the insertion block 27 are driven to move by the action of the spring 28, so that the insertion block 27 is inserted into the inside of the connecting column 26, thereby limiting and fixing the connecting column 26.
