Description

Technical Field

[0001] The utility model relates to the technical field of mold polishing equipment, in particular to a mold polishing equipment. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts.

[0003] When the mold is produced, its surface and grooves need to be polished by polishing equipment. However, the existing handheld polishing equipment has a non-adjustable length, so it is not flexible when grinding grooves of different depths. Secondly, a lot of dust will be generated during the grinding and polishing process. The dust covers the grinding surface, affecting the workers' observation of the polishing gloss.

[0004] After searching, a mold polishing device disclosed in patent publication number CN217168017U is found. Although the polishing device can solve the technical problems existing in the handheld polishing device in the prior art, it still has certain disadvantages in actual use. When adjusting the telescopic rod, the polishing device is only locked and fixed by a locking bolt. During grinding, the high-speed rotation of the grinding disc will cause vibration of the equipment, which will make the locking bolt loose, thereby having a poor fixing effect on the telescopic rod, easily causing the telescopic rod to move, and affecting the polishing stability of the grinding disc.
