Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides the following technical solution: a surface polishing device for precision molds, including a universal wheel 1, a base 2 fixedly mounted on the upper part of the universal wheel 1, support rods 9 respectively arranged around the perimeter of the surface of the base 2, a top frame 12 mounted on the top of the support rods 9, a transverse fixing frame 3 slidably mounted on the upper part of the base 2, an operating table 4 fixedly mounted in the middle of the transverse fixing frame 3, movable plates 5 movably connected to both sides of the transverse fixing frame 3, a first threaded rod 23 arranged on one side inside the transverse fixing frame 3, a second threaded rod 24 arranged on the other side inside the transverse fixing frame 3, and the first threaded rod 23 and the second threaded rod 24 are connected to each other, and a first hand crank 8 is connected to one end of the first threaded rod 23. The surfaces of the first threaded rod 23 and the second threaded rod 24 are respectively threaded with clamping plates 6, and the clamping plates 6 are located inside the transverse fixing frame 3. An electric push rod 7 is provided on one side of the support rod 9, and the output end of the electric push rod 7 is connected to the transverse fixing frame 3. A fixing device is fixedly installed on the inner side of the clamping plate 6. A rotating rod 13 is installed on the inner side of the top frame 12. One end of the rotating rod 13 is connected to a second hand crank 18. A fixing block 25 is threadedly connected to the surface of the rotating rod 13. An electric hydraulic push rod 14 is installed at the bottom of the fixing block 25. The output end of the electric hydraulic push rod 14 is connected to the mounting plate 26. A motor 16 is fixedly installed on one side of the bottom of the mounting plate 26. A polishing wheel 15 is installed at the output end of the motor 16.

[0024] In this embodiment, the presence of casters 1 allows staff to move the device relatively easily, making it convenient for staff to move the device to a suitable location for use.

[0025] In this embodiment, a push-pull rod 10 is provided to make it easy for staff to push the device.

[0026] In this embodiment, the slide rail 22 allows the operator to move the transverse fixed frame 3 laterally using the electric push rod 7.

[0027] In this embodiment, the rotating rod 13 allows the operator to control the second threaded rod 18 to adjust the polishing and grinding device back and forth.

[0028] In this embodiment, the movable plate 5 is provided so that workers can disassemble it at any time to clean the movable plate 5 and the grinding debris generated in the horizontal fixing frame 3.

[0029] In this embodiment, the movable wheel under the clamping plate 6 makes it easier and more convenient for the operator to operate the first threaded rod 8.

[0030] In this embodiment, a desktop 11 is provided so that staff can place tools or personal belongings.

[0031] The working principle and usage process of this utility model are as follows: After the utility model is installed, the mold is placed on the surface of the operating table 4. Then, by rotating the first hand crank 8, it drives the first threaded rod 23 and the second threaded rod 24 to rotate, thereby causing the first threaded rod 23 and the second threaded rod 24 to move the clamping plate 6 closer to the mold. As the mold comes into contact with the rubber head 21, the spring inside the fixing rod 20 is compressed and fixed, and the rotation of the first hand crank 8 is stopped to achieve the purpose of fixing the mold. The electric push rod 7 causes the transverse fixing frame 3 to move left and right along the slide rail 22. The transverse fixing frame 3 also drives the fixed mold to the target position. Then, by rotating the second hand crank 20... The hand crank 18 drives the rotating rod 13 to rotate, which in turn causes the fixed block 25 to move vertically back and forth. The electric hydraulic push rod 14, mounting plate 26, motor 16, and polishing wheel 15 located below the fixed block 25 also move back and forth with the fixed block 25. After reaching the target position, the electric hydraulic push rod 14 works, causing the motor 16 fixed on the mounting plate 26 to move downward, which in turn causes the polishing wheel 15 to move downward and make it contact the mold. Then the motor 16 works, causing the polishing wheel 15 to rotate, so that it can grind and polish the mold. All electrical equipment in this device is powered by an external power source.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
