[0002] In the field of mold manufacturing, the polishing quality of the mold appearance has a vital impact on the performance, service life and quality of the products produced by the mold. Traditional mold appearance polishing methods mainly include manual polishing and mechanical polishing. Manual polishing relies on the experience and operating skills of workers, which is inefficient and difficult to ensure the consistency of polishing accuracy. Especially when dealing with complex-shaped molds, it not only consumes a lot of manpower and time, but also makes it difficult to achieve high-precision polishing requirements. Although mechanical polishing has improved efficiency to a certain extent, for molds with special-shaped structures and complex curved surfaces, conventional mechanical polishing equipment often finds it difficult to achieve comprehensive and accurate polishing, and is prone to problems such as uneven polishing and missing some areas.
