[0002] Injection molded parts refer to various injection molded products produced by injection molding machines, including various packages, parts, etc. They are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. The existing polishing device for injection molded parts (Announcement No.: CN220463361U) has the following disadvantages in use:

[0003] During use, the vacuum pump generates suction at the drop port, sucks the debris generated during grinding into the telescopic hose, and then drops it into the collection drawer and is filtered through the filter. When more injection molded parts need to be polished, more debris will be generated. More debris will be accumulated on the filter, affecting the normal operation of the vacuum pump and even causing a decrease in work efficiency or damage to the equipment. For this reason, this patent proposes a polishing device for injection molded parts to solve the above problems. Utility Model Content
