The maintenance of glass bottle mould is mainly to repair the damaged parts, remove the oxide skin and finish the surface polishing, so as to achieve the necessary condition.

The first removal of the mould from the bottling machine is to remove the fouling and oxidation of the lubricant. The methods of cleaning are: manual mechanical cleaning, sandblasting cleaning, direct chemical cleaning and electrochemical cleaning. The first two methods are most commonly used, the blasting cleaning method is efficient. It has the dry method and wet method to deal with two kinds, the abrasive has fine quartz sand, fine corundum sand, glass microbeads, dry method abrasive.

The main failure modes of glass bottle forming die include oxidation (peeling, peeling, pitting), chamfering and deformation. Scaly flaking is the main form of discarded glass bottle forming die. The key factor affecting the service life of the mould is the heat resistance of the material, which is the ability of the material to resist oxidation and resist growth at high temperature. It depends on the matrix and the graphite form.

Iron is added to copper, chromium, tin and so on, which can promote the generation of pearlite and improve the hardness of cast iron, so as to improve the ability of anti-chamfering, abrasion resistance and wear resistance. Add silicon, aluminum and other elements to form dense SiO2 and Al2O3 surface oxidation film, thus improving the surface antioxidant capacity of the mold.

The material of glass mold is made of gray iron is heat-resistant, in the process of production is not easy degradation, but after a long time to use at high temperatures and the oxidation of release agent how much will a bit damaged. The mold is pulled down without cleaning and maintenance. Use high pressure air pump and fine sand and water to clean, then repair with the welding gun and then wipe the butter.
