In the above patent, a polishing box is set up, a dust collection device is installed at the top of the polishing box, a polishing component is installed inside the polishing box, and a mold positioning component is installed on the inner bottom wall of the polishing box. The mold is positioned by the mold positioning component, and the mold is polished by the polishing component, thereby achieving the purpose of polishing the mold.

[0004] While the aforementioned patents can achieve the purpose of polishing, they have the following problems in use: In existing technology, the polishing block moves vertically, while the mold also moves back, forth, left, and back. This results in the polishing block only being able to move in a straight line, thus only polishing horizontal mold surfaces. However, the inner cavity of the mold is uneven, and the polishing structure in existing technology cannot meet the requirements for polishing mold surfaces at different angles.

A left-to-right moving electric cylinder is arranged between the lifting sliders, and each left-to-right moving electric cylinder has a left-to-right moving slider. The horizontal rotation motor is installed on the left-to-right moving slider.

[0008] Preferably, the transition connecting seat has a U-shaped structure, and the transition connecting seat includes an upper seat plate and a plurality of first side plates and second side plates located at the bottom of the upper seat plate.

The horizontal rotation motor 4 is installed on the left and right moving sliders 306. like Figure 6 and Figure 7 As shown, the transition connecting seat 5 has a U-shaped structure. The transition connecting seat 5 includes an upper seat plate 501 and a plurality of first side plates 502 and second side plates 503 located at the bottom of the upper seat plate 501. The first side plates 502 and second side plates 503 are movably connected to the upper seat plate 501, which facilitates the installation and fixing of the rotating connecting plate 6.

[0030] In this patent, the rotating connecting plate 6 is located between the first side plate 502 and the second side plate 503. The first side plate 502 and the second side plate 503 are respectively provided with bearing holes 504, and bearings 505 are installed in the bearing holes 504. By providing multiple bearings 505, the rotation of the rotating connecting plate 6 can be realized.

[0031] like Figure 8 As shown, the rotating connecting plate 6 includes a connecting plate body 601. A left connecting roller 602 and a right connecting roller 603 are respectively provided on the left and right sides of the connecting plate body 601. The left connecting roller 602 and the right connecting roller 603 are respectively inserted into the bearing 505, which facilitates the rotation of the rotating connecting plate 6.
