Description

Technical Field

[0001] The invention relates to the technical field of glass mold punch processing attachments, in particular to a glass mold punch longitudinal polishing device. Background Art

[0002] As we all know, in the processing of glass bottles, whether it is the blow-blowing method or the press-blowing method, a glass mold punch must be used. The punch is inserted into the glass liquid from the bottom of the mold to make a preliminary mold. In order to ensure the smoothness of the punch surface, the surface of the mold punch needs to be polished. At present, the industry generally uses a chuck to fix the punch for polishing glass mold punches. The chuck and punch are driven by a motor to rotate at high speed, and then the punch surface is polished with sandpaper. This polishing method produces a horizontal stripe structure on the surface of the punch. When the punch is inserted into the glass liquid, the horizontal stripe is perpendicular to the direction of travel of the punch, which increases the friction between the punch and the glass liquid, and also affects the smoothness of the inner surface of the glass bottle.
