[0002] The existing 3D curved glass forming process is to put the 2D original sheet glass into a graphite mold for high-temperature hot bending to form a certain special curved shape. The graphite mold used in the hot bending process is easy to contaminate dust and oxidized dust and other impurities during frequent use. If there is dust and impurities in the mold cavity, it will directly cause the glass surface after hot bending to have concave-convex points or other undesirable features. Therefore, before putting the original sheet glass into the mold for hot bending forming each time, manual cleaning of the mold with a cleaning cloth is required to remove the impurities on the mold. However, this not only has a complicated operation, high labor intensity and low work efficiency, but also has an unsatisfactory cleaning effect.

The utility model can effectively clean the hot bending mold that needs to be cleaned, and the closed cleaning environment effectively avoids the entry of external dust, ensures the quality of the cleaned hot bending mold, does not need manual cleaning, reduces the labor intensity, and improves the work efficiency. However, this device requires manual placement of the hot bending mold, which results in the need for improvement of the cleaning efficiency of the hot bending mold. Utility model content
