[0035] The transmission mechanism includes a fixed plate 22, which is installed below one end of the L-shaped seat 9. A second screw rod 21 is rotatably installed inside the fixed plate 22. The second motor 10 is connected to the end of the second screw rod 21 away from the fixed plate 22. The second motor 10 is fixedly arranged on the outer side of the end of the L-shaped seat 9 away from the fixed plate 22. The second screw rod 21 is externally threaded with a mounting seat 19. The mounting seat 19 slides on the lower end of the L-shaped seat 9. The support frame 11 is fixedly arranged on the lower end of the mounting seat 19.

[0036] Reference Manual Attached Figure 3 It can be seen that, driven by the second motor 10, the second screw rod 21 drives the mounting seat 19 to move at the lower end of the L-shaped seat 9, and the mounting seat 19 and the support frame 11 can move synchronously, so it is convenient to adapt to the movement of the mold cavity at different positions of the mold body 12 during polishing later.

[0037] The reciprocating mechanism includes a third motor 32 fixedly mounted on the upper part of the U-shaped frame 20, a screw 35 is fixedly arranged at the output end of the third motor 32, a clamping shaft is fixedly sleeved at the lower end of the screw 35, the clamping shaft is rotatably mounted at the lower part of the U-shaped frame 20, a second gear 31 is sleeved on the outer side of the clamping shaft, a rotating sleeve 29 is rotatably mounted at the lower part of the outer side of the clamping tube 27, a first gear 28 is fixedly sleeved on the outer side of the rotating sleeve 29, the first gear 28 is meshedly connected with the second gear 31, and a cleaning piece is arranged on the lower end surface of the rotating sleeve 29;

[0038] Reference Manual Attached Figure 4 and Figure 5 It can be seen that the third motor 32 drives the screw 35 to rotate, and the card shaft connected to the lower end of the screw 35 rotates together, and the second gear 31 outside the card shaft can engage with the first gear 28. Under the rotation connection between the rotating sleeve 29 and the first gear 28, the cleaning piece can rotate under the rotating sleeve 29.

[0039] The cleaning member includes a metal magnetic rod 26 installed at equal distances along the circumferential direction on the lower end surface of the rotating sleeve 29, the metal magnetic rod 26 is located outside the polishing shell 33, and the lower part of the polishing shell 33 is provided with a cavity;

[0040] Reference Manual Attached Figure 4 and Figure 5 It can be seen that the metal magnetic rod 26 can be used to process the metal scraps generated from the mold body 12 inside the mold cavity when the mold is closed. Each time the grinding shell 33 penetrates into the mold cavity, the metal scraps on the surface will be pushed to the outside and upward, and then adsorbed by the metal magnetic rod 26.

[0041] Working principle: When in use, the mold body 12 is placed on the upper end surface of the U-shaped seat 8, and the two groups of second hydraulic cylinders 37 drive the clamping plates 13 to approach each other to clamp the mold body 12. Under the drive of the first motor 7, the first screw rod 15 drives the T-shaped seat 17 and the L-shaped seat 9 to move horizontally inside the frame seat 5. The second motor 10 drives the second screw rod 21 to rotate, and the mounting seat 19 outside the second screw rod 21 can slide under the L-shaped seat 9, so that the U-shaped frame 20 can move longitudinally, so as to grind different mold cavities inside the mold body 12. Driven by the lifting assembly, the grinding shell 33 slides back and forth in the mold cavity along the vertical direction. After the inside of the mold cavity at the corresponding position is corrected and smooth, the third motor 32 drives the screw rod 35 to rotate, so that the extension rod 34 slides vertically outside the screw rod 35, and the frame plate 23 slides outside the clamping tube 27 When the frame 23 moves, the dust collector 24 synchronously drives the correspondingly arranged suction pipe 36 to slide inside the clamping pipe 27. After the polishing shell 33 moves upward from the inside of the mold cavity to leave space, the suction pipe 36 moves downward to process the waste chips deep in the mold cavity. As a result, after the mold is corrected, the waste chips deep in the mold cavity that are not easy to process can be processed in time. When the screw 35 rotates, the card shaft fixed at the bottom end can drive the second gear 31 to rotate, and then the first gear 28 drives the rotating sleeve 29 and the multiple metal magnetic rods 26 on the lower end face to rotate. When the polishing shell 33 goes deep into the mold cavity and the bottom contacts the bottom wall of the mold cavity, the metal chips on the outer surface of the polishing shell 33 that contact the mold cavity can be pushed to the upper surface and then adsorbed by the metal magnetic rod 26. As a result, different waste chips can be processed when polishing the mold body 12, further improving the quality after polishing.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
