Abstract
A manufacturing method of a vehicle-mounted curved glass cover plate hot forming die comprises the following steps: s1, spraying the high-temperature alloy on the surface of the metal grinding tool by a plasma thermal barrier spraying technology to form a ceramic oxide coating; and S2, grinding and polishing the surface of the metal grinding tool by using a grinding machine to finish the manufacture of the hot forming die. The invention forms a ceramic oxide coating with the thickness of more than 1 mm by spraying the high-temperature alloy on the surface of the metal grinding tool through a plasma thermal barrier spraying technology, thereby preventing powder falling.
Description
Technical Field
The invention relates to the technical field of glass thermoforming precision processes, in particular to a manufacturing method of a thermoforming mold for a vehicle-mounted curved glass cover plate.
Background
At present, most of hot bending glass takes graphite as a material of a mold, the graphite mold has the advantages of low price, easy processing and the like, but when the die is used for producing high-alumina-silica glass (the softening point is over 800 ℃), the die can bear cold and hot impact for a long time, the graphite mould is easy to fall off powder, the surface of the graphite mould is easy to have air holes, the service life of the mould is short, more important curved glass after hot bending needs to be subjected to processes such as polishing and the like, in order to solve the problems of the graphite mould that the powder falls off and the air holes, not only new moulds need to be continuously put into production, because the mold is continuously replaced, the quality of the hot-bent glass product is easy to generate various variations, the difficulty in mass production management is caused, and then, aiming at the re-polishing of the glass after hot bending forming, the working hours, equipment capital investment, a large amount of consumables and management cost are increased, so that the output efficiency is greatly reduced.
