[0038] Then, the front of the lower part of connecting plate 3 is provided with engaging plate 4, engaging plate 4 and connecting plate 3 are connected with each other through the transmission device, for driving engaging plate 4 to move to the appropriate position, wherein the transmission device comprises sliding block 10 slidably connected to the front of the bottom end of connecting plate 3, the bottom end of sliding block 10 is fixedly connected with a plurality of electric push rod two 11, the bottom end of electric push rod two 11 is fixedly connected on engaging plate 4, at the same time, the rear end of sliding block 10 is fixedly connected with electric push rod three 12, the rear end of electric push rod three 12 is fixedly connected on connecting plate 3 through the engaging frame 13, the operation of electric push rod three 12 indirectly drives sliding block 10 to move back and forth;

[0039] The bottom end of engaging plate 4 is fixedly connected with a polishing machine, for performing polishing operation, at the same time, blowing device 5 is arranged on one side of engaging plate 4, for removing the waste generated before or during polishing, to increase the accuracy of subsequent polishing;

[0040] At the same time, electric push rod one 8 is fixedly connected on both sides of the middle of the top end of base 1, the top end of each electric push rod one 8 is fixedly connected with support plate 7, the top end of the two support plates 7 is movably connected with polishing workbench 6, it is to be explained that the top end of polishing workbench 6 is provided with a mold placing groove, the setting of the placing groove is to stably place the mold in it, so as to realize the accurate positioning and limiting of the mold in the polishing process. A plurality of anti-skid blocks are fixedly connected on the bottom wall of the placing groove, the function of these anti-skid blocks is to enhance the friction between the mold and polishing workbench 6, to further ensure the stability and safety of the mold in the polishing process, to prevent the mold from moving or sliding in the polishing process;

[0041] Finally, the polishing workbench 6 is provided with an angle adjusting device 9 at the bottom end, which is used for adjusting the rotation of the polishing workbench 6 to a suitable angle, so as to realize fine polishing treatment on different areas of the mold.

[0042] The above-mentioned various structures jointly constitute the general appearance structure of the polishing device.

[0043] In the embodiment 1, the blowing device 5 comprises a connecting frame 501 fixedly connected to one side of the joint plate 4, two rotating frames 502 fixedly connected to the side of the connecting frame 501 away from the joint plate 4, rotating holes formed in the two rotating frames 502, rotating shafts 503 rotatably connected in the rotating holes, and blowing tubes 504 fixedly connected to the proximal ends of the two rotating shafts 503.

[0044] The driving motor 507 is arranged on the rotating frame 502, and the output shaft of the driving motor 507 penetrates through the rotating hole and is fixedly connected to the corresponding rotating shaft 503, so that the driving motor 507 can drive the rotating shaft 503 and the blowing tube 504 connected to the rotating shaft 503 to rotate.

[0045] Finally, the air pump 505 is fixedly connected to the top front end of the connecting plate 3, and the air pump 505 and the blowing tube 504 are connected through a connecting hose 506. Through the connecting hose 506, the air pump 505 can effectively deliver strong wind to the inside of the blowing tube 504, so as to ensure that the blowing tube 504 can generate sufficient wind power for cleaning the waste generated in the polishing process and keeping the working area clean.

[0046] It should be noted that the connecting hose 506 has sufficient length, and a plurality of limiting frames are fixedly connected to the outer wall of the connecting hose 506, which are fixedly connected to the corresponding parts to ensure that the connecting hose 506 can run stably and will not interfere with the use of the remaining parts.

[0047] The technical effects achieved by the above technical features are that during the polishing process of the mold, the air pump 505 is started and generates high-pressure gas, which is delivered to the blowing tube 504 through the connecting hose 506. Then, the blowing tube 504 converts the high-pressure gas into strong air flow to perform blowing operation on the specified area, effectively reduces the damage of the waste to the surface of the mold, and improves the precision of the polishing operation.

[0048] In this process, the drive motor 507 continues to operate the positive and negative rotation, driving the rotating shaft 503 and the blow tube 504 on it to reciprocating swing. This swing action not only expands the coverage area of the blowing operation, but also further enhances the blowing effect, ensuring that the debris during the mold polishing process can be completely removed, thereby improving the overall polishing quality and efficiency.

[0049] In the above-mentioned angle adjusting device 9, a servo motor one 901 is arranged at the rear of the middle part of the top end of the base 1, the servo motor one 901 is fixedly connected to the base 1 through the motor seat two, the front end of the servo motor one 901 is fixedly connected with a concave-shaped fixed frame one 902, a rotating block 903 is arranged in the fixed frame one 902, and the two sides of the rotating block 903 are rotatably connected to the corresponding side walls of the fixed frame one 902 through the transmission shafts.

[0050] The top end of the rotating block 903 is fixedly connected to the polishing workbench 6, and when the rotating block 903 rotates, the polishing workbench 6 fixedly connected thereto can rotate together;

[0051] The front end of the rotating block 903 is fixedly connected with a connecting shaft 904, the front end of the connecting shaft 904 is rotatably connected with an L-shaped fixed frame two 905, one side of the fixed frame two 905 is fixedly connected with a servo motor two 906, and the servo motor two 906 is fixedly connected to the base 1 through the motor seat three.

[0052] Therefore, the rotating block 903 can drive the polishing workbench 6 to rotate to a suitable angle by cooperating with the fixed frame one 902 and the fixed frame two 905.

[0053] The above technical features achieve the following technical effects: the servo motor one 901 drives the fixed frame one 902 to rotate, and then indirectly drives the polishing workbench 6 to rotate around the output shaft of the servo motor one 901 in the circumferential direction through the rotating block 903. At the same time, the servo motor two 906 indirectly drives the rotating block 903 to rotate through the fixed frame two 905 and the connecting shaft 904, so that the rotating block 903 can drive the polishing workbench 6 to rotate around the output shaft of the servo motor two 906 in the circumferential direction.

[0054] In summary, through the cooperative work of the servo motor one 901 and the servo motor two 906, the precise angle adjustment of the rotating block 903 to the polishing workbench 6 is realized, so that the polishing workbench 6 can be rotated to a predetermined suitable angle, thereby meeting the needs of different mold polishing operations and improving the flexibility and adaptability of the polishing device.

[0055] It should be noted that the servo motor 901 and the servo motor 906 are self-locking, and the servo motor 901 and the servo motor 906 are arranged to rotate within a limited range, which does not affect the normal operation of the remaining equipment.

[0056] In actual operation, first, the mold is placed stably in the placing groove of the polishing workbench 6, ensuring that the mold is in close contact with the groove wall to achieve stable fixation. Then, start the polisher, and use the coordinated action of the electric push rod two 11 and the electric push rod three 12 to indirectly push the polisher to move to the appropriate position through the sliding block 10. In this process, the polisher will continuously polish the specified part of the mold.

[0057] During the polishing operation, the air pump 505 is in a continuous running state, so that the air gun 504 can continuously blow the polishing part of the mold and its surrounding area, effectively blowing away the generated debris, thereby improving the polishing precision and cleanliness.

[0058] When different angle polishing operations are required for the mold, the electric push rod one 8 on both sides will drive the corresponding support plate 7 to descend, providing more space for the polishing workbench 6. Finally, through the operation of the angle adjusting device 9, the polishing workbench 6 is accurately adjusted to the required angle position, so as to complete the multi-angle polishing task.

[0059] The above describes the present application and its embodiments, which are not limited, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired by it, without departing from the spirit of the present application, without creative design, similar structure and embodiments of the technical solution can be designed, which should belong to the protection scope of the present application.
