Description

Polishing device for plastic products

Technical Field

The utility model relates to the technical field of injection molding products, in particular to a polishing device for plastic products.

Background

Injection molding (Injection molding) is a common plastic product processing technique used for producing a large number of plastic products, ranging from small parts to large parts. This process involves injecting molten plastic material into a mold by high pressure, filling the mold cavity, and then cooling and solidifying within the mold to finally obtain a plastic article of the desired shape.

The surface of the injection molded product may be unsmooth, defective or marked, which may reduce the aesthetic quality and texture of the product. The polishing can eliminate the defects, so that the surface of the product is smoother and more uniform, and the appearance quality is improved. And the products after injection molding may exhibit a certain degree of uneven gloss or lower gloss. The glossiness of the product can be adjusted by polishing, so that the product is more uniform and brighter, and the visual attractiveness of the product is enhanced. Also during injection molding, a mold or other process may leave behind cuts, imperfections, or uneven surfaces. The polishing can remove the flaws, so that the surface of the product is smoother, and the overall quality of the product is improved. Most importantly, the injection molding process may result in inaccurate product dimensions or the presence of small bumps or depressions. The polishing can finely adjust the product to achieve the dimensional accuracy required by the design. For example, for products contacted with human bodies, such as plastic tableware, toys and the like, polishing can enable the surface of the products to be smoother, avoid skin irritation and improve comfort and safety.

Therefore, the product after injection molding also needs to be subjected to a polishing process for improving the quality, the smoothness and the appearance aesthetic quality of the surface of the product. In the manual mode, a worker holds the grinding material (such as sand paper, grinding wheel and grinding cloth) and the polishing agent to polish. Because of its inefficiency, polishing machines are now commonly used to perform polishing operations. However, when the polishing machine faces a product with curvature characteristics, the following technical problems exist:

Conventional polisher technology has the disadvantage of being difficult to adapt to the polishing requirements of the curved surface product. This results mainly from the rigid structure and the manner of movement of the conventional polishing machine. Conventional polishing machines are often designed as rigid structures, the motion profile and angle of the polishing tool (e.g., polishing wheel or brush) of which is usually fixed or can be simply adjusted. The design cannot be fully adapted to the surfaces of products with different curvatures, and particularly when products with larger curvatures or irregularly-shaped curved surfaces are processed, the traditional polishing machine can not realize accurate polishing coverage, so that polishing is uneven or partial areas are omitted.

For this purpose, a polishing device for plastic products is proposed.
