Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a surface treatment device for injection mold products. Background Technology

[0002] Injection-molded products are plastic products manufactured using the injection molding process. Injection molding is a production technology that uses plastic molds to form plastic products of various shapes from thermoplastic or thermosetting plastics. After injection molding, unnecessary burrs and scraps will exist. Therefore, the surface of the molded product needs to be polished. A Chinese utility model patent (publication number: CN219337179U) discloses a surface treatment device for injection-molded products. By continuously and automatically transferring the injection-molded products to the ground surface, the device enables continuous grinding operations, greatly improving production efficiency and possessing high practical value.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, in the prior art, when installing the workpiece to be processed on each placement seat, it is necessary to use a positioning component consisting of a positioning hole, a pressure seat, and a threaded rod to position the workpiece. After the workpiece is polished, the positioning component needs to be manually removed again to install a new workpiece. The overall work is labor-intensive and inefficient for the workers. Therefore, in view of the above situation, a surface treatment device for injection mold products is proposed. Utility Model Content
