[0002] Mold polishing removes surface roughness and adjusts the degree and shape of the surface to achieve the desired surface quality. For products requiring high-precision machining, the quality of the mold surface directly affects the accuracy and quality of the product. After polishing, the mold surface finish, flatness, and brightness can be significantly improved, thereby ensuring part quality.

The interior of the base 2 is connected to two round rods 17, and the outer surfaces of the two round rods 17 are slidably connected to the interior of the L-shaped connecting plate 6. The two round rods 17 can limit the moving trajectory of the two L-shaped connecting plates 6 so that the two polishing discs 13 can move toward each other and adapt to molds of different thicknesses, with good applicability.

[0035] The working principle of a mold surface polishing device provided by the utility model is as follows:

[0036] By moving the side plate 21, the side plate 21 can drive the positioning protrusion 19 equipped with the first spring 20 to be compressed and enter the interior of the rotating shaft seat 11, and then the clamping block 12 is clamped into the rotating shaft seat 11, and the clamping block 12 can drive the polishing disc 13 to be fixed. Then, the side plate 21 is loosened, and the elastic force of the first spring 20 can make the positioning protrusion 19 automatically extend and further clamp the fixed clamping block 12, and then cooperate with the two T-shaped plates 14 at the clamping block 12 to firmly position the entire polishing disc 13. In this way, the clamping method is convenient for flexibly replacing polishing discs 13 of different sizes, which is convenient for meeting the polishing requirements of different molds. Then, the output shaft of the second servo motor 18 drives the double-headed screw rod 5 to rotate, so that the two L-shaped connecting plates 6 on the double-headed screw rod 5 can move towards each other, so that the two polishing discs 13 can be moved to the two sides of the mold body 4, so that the two sides of the mold can be polished at the same time, without adjusting the position of the mold, saving time and effort, and improving the polishing efficiency of the mold surface polishing device;

[0037] By moving the two L-shaped connecting plates 6 toward each other, the two telescopic plates 31 equipped with the second spring 32 can also move together, so that the brush strips 111 at the two telescopic plates 31 can clean the polishing debris on the base 2, and the polishing debris will enter the debris box 30 along the chute 16 for centralized treatment, so as to clean the debris in time and reduce the labor intensity of the staff. Then, the two bolts 26 are rotated respectively, and the bolts 26 can drive the second circular clamping plate 27 to clamp to the two ends of the mold. Then, the second electric push rod 23 drives the first circular clamping plate 24 to move downward for re-positioning the mold to ensure the stability of the mold during polishing, avoid shaking and offsetting of the mold, and improve the polishing accuracy.
