Technical Field
[0001] This utility model relates to the field of polishing equipment technology, specifically to a surface polishing equipment for mold processing. Background Technology
[0002] Surface polishing in mold processing is a crucial step in ensuring mold precision, smoothness, and lifespan. Surface polishing equipment removes burrs, corrects microscopic defects, and improves smoothness, directly affecting mold release performance, product molding quality, and production efficiency.
[0003] In mold manufacturing and maintenance, surface polishing is a crucial process for improving the surface finish and precision of molds. It is widely used in the processing of various types of molds, including injection molds, stamping molds, and die-casting molds. In existing technologies, to control temperature rise during polishing and promptly remove cutting debris, coolant is typically used to cool and flush the polished area. However, for molds that have undergone surface treatments, such as those with sprayed coatings, PVD physical vapor deposition, or nitriding, the coolant can wash away the functional treatment layer covering the mold surface during polishing, or cause interlayer delamination between the treatment layer and the mold substrate. This type of surface treatment reduces the wear resistance, corrosion resistance, and service life of the mold surface. It is often formed through multiple processes, and once damaged, the mold will be scrapped directly. In addition, when coolant cannot be used, a large amount of cutting debris generated during the grinding process cannot be removed in time and tends to accumulate in the grinding area, resulting in reduced grinding efficiency and accelerated tool wear. At the same time, the debris is prone to scratches on the mold surface under high-speed grinding, affecting the surface quality and causing a decrease in mold precision or rework. Obviously, the existing mold surface grinding technology has obvious problems of insufficient adaptability and unstable grinding quality when facing the above-mentioned mold processing scenarios where coolant cannot be used.
[0004] In view of this, we propose a surface polishing device for mold processing. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 - Figure 4As shown, this utility model provides a technical solution: a surface polishing device for mold processing, including a base 1, a worktable 2, and a polishing head 3. The worktable 2 is arranged on the base 1, and the polishing head 3 is arranged on the worktable 2. The worktable 2 is used to place and fix the mold, and the polishing head 3 is used to polish the surface of the mold. A dust collection mechanism 4 is arranged on the polishing head 3. The dust collection mechanism 4 includes: a hollow ring block 41, which is fixedly connected to the outer wall of the polishing head 3. A telescopic tube 42 is arranged on one side of the hollow ring block 41, and a dust collection box 43 is arranged on the other side of the hollow ring block 41. A filter screen 44 is provided on the side of the dust collection box 43 away from the hollow ring block 41. A toothed ring 45 is rotatably connected to the inner wall of the hollow ring block 41, and a suction pipe 46 is fixedly connected to the inner wall of the toothed ring 45. The telescopic pipe 42 is connected to the output end of the air compressor, so that compressed air enters the hollow ring block 41 through the telescopic pipe 42 and is discharged through the dust collection box 43. Under the action of Bernoulli's principle, the suction pipe 46 generates suction force, which sucks away the debris generated during the operation of the grinding head 3 and carries away the heat. The debris is then returned to the hollow ring block 41 through the suction pipe 46. The debris is then collected in the dust collection box 43. A filter screen 44 prevents debris from leaking out. A vibration mechanism 5 is installed on the dust collection box 43 to tap the filter screen 44 to prevent debris blockage. The filter screen 44 is tilted to allow debris to fall off under gravity. A sealing ring is installed between the toothed ring ring 45 and the hollow ring block 41 to prevent air leakage from the hollow ring block 41 through the gap. A positioning block 47 is fixedly connected to the top of the hollow ring block 41. A return spring 48 is installed on the outer wall of the positioning block 47, with one end of the return spring 48 fixedly connected to the positioning block 47. The other end of 48 is fixedly connected to a triangular prism block 49. Under the action of the return spring 48, the triangular prism block 49 abuts against the toothed ring 45, so that the toothed ring 45 is further positioned and prevented from rotating during operation. The filter screen 44 is a detachable structure, which is convenient for regular replacement or cleaning. The telescopic tube 42 is a corrugated flexible tube structure, which can be flexibly deformed with the movement of the grinding head 3 to avoid pulling. The dust collection box 43 is a transparent shell structure, which is convenient for observing the internal debris accumulation and maintenance cycle. The bottom of the dust collection box 43 is provided with an openable dust outlet, which is convenient for regular cleaning of the collected debris.
[0025] The oscillation mechanism 5 includes a main shaft 51, which is rotatably connected to the inner wall of the dust collection box 43. An impeller 52 is mounted on the main shaft 51. A secondary shaft 53 is rotatably connected to the dust collection box 43. A belt 54 drives the secondary shaft 53 and the main shaft 51. A cam 55 is mounted on the secondary shaft 53. The air in the dust collection box 43 drives the impeller 52 to rotate, which in turn drives the main shaft 51 to rotate. The main shaft 51 drives the secondary shaft 53 to rotate via the belt 54. The secondary shaft 53 drives the cam 55 to rotate, which vibrates and strikes the filter screen 44, automatically cleaning debris from the filter screen 44, preventing clogging, and ensuring stable dust collection performance. The belt 54 has an anti-slip toothed structure, and the filter screen 44 has reinforcing ribs at positions corresponding to the cam 55 to improve its fatigue life against impact.
[0026] In use, the surface polishing equipment for mold processing of this utility model connects the telescopic pipe 42 to the output end of the air compressor, so that the compressed air enters the hollow ring block 41 through the telescopic pipe 42 and is discharged through the dust collection box 43. Under the action of Bernoulli's principle, the suction pipe 46 generates suction force, so that the debris generated during the working process of the polishing head 3 is sucked away and the heat is carried away. The debris enters the hollow ring block 41 through the suction pipe 46 and then enters the dust collection box 43 for collection. The filter screen 44 prevents the debris from leaking out.
[0027] Pull the triangular prism block 49 and then rotate the toothed ring 45 to drive the suction pipe 46 to absorb debris and heat at different angles. After rotating the toothed ring 45, release the triangular prism block 49. Under the action of the return spring 48, the triangular prism block 49 will resist the toothed ring 45, so that the toothed ring 45 is further positioned to prevent the toothed ring 45 from rotating during operation.
[0028] The air in the dust collection box 43 drives the impeller 52 to rotate, the impeller 52 drives the main shaft 51 to rotate, the main shaft 51 drives the secondary shaft 53 to rotate via the belt 54, and the secondary shaft 53 drives the cam 55 to rotate to vibrate and knock on the filter screen 44, automatically cleaning the debris on the filter screen 44, preventing clogging, and ensuring stable dust collection effect.
