Description

Technical Field

[0001] The invention relates to the technical field of hole wall grinding in plastic mold processing, and in particular to a hole wall grinding device used for plastic mold processing. Background Art

[0002] Plastic molds are tools used in the plastic processing industry to match plastic molding machines and give plastic products complete configurations and precise dimensions. Due to the wide variety of plastics and processing methods, the structures of plastic molding machines and plastic products vary in complexity, and the types and structures of plastic molds are also diverse.

[0003] During the production of plastic molds, after the holes in the plastic molds are opened, the inner wall of the hole needs to be polished to eliminate the bumps or burrs on the inner wall of the hole. During the transmission polishing operation, the mold is placed on the polishing table and then polished with a grinding wheel. The debris generated by the polishing will remain in the hole, or the debris will splash, and particulate dust will be generated. In addition, each component of the polishing device uses an independent drive. The setting of multiple drives not only increases the cost of the device but also increases the cost of use. For this reason, we propose a hole wall polishing device for plastic mold processing. Summary of the invention
