Oxidization-preventing device of curved glass forming mould and curved glass forming machine

Abstract

The invention provides an oxidization-preventing device of a curved glass forming mould and a curved glass forming machine, and relates to the technical field of curved glass processing. The oxidization-preventing device of the curved glass forming mould comprises a heat-insulating box body, a communication pipeline and a nitrogen gas tank, wherein a sealed cavity for placing the mould is arrangedin the heat-insulating box body; the heat-insulating box body is used for isolating the sealed cavity from the outside; a pipeline joint which is communicated with the sealed cavity is arranged on the heat-insulating box body; one end of the communication pipeline is connected with the pipeline joint, and the other end of the communication pipeline is connected with the nitrogen gas tank for leading nitrogen gas in the nitrogen gas tank into the sealed cavity. The oxidization-preventing device solves the technical problem that a glass heating and forming room is filled up with air and is un-tight in sealing in the prior art. The heat-insulating box body provided by the invention realizes sealing on the sealed cavity; and the nitrogen gas is lead in, so that discharge of oxygen gas in thesealed cavity is realized.

Description

technical field [0001] The invention relates to the technical field of curved glass processing, in particular to an anti-oxidation device for a curved glass forming mold and a curved glass forming machine. Background technique [0002] Curved glass has the characteristics of light and thin, transparent and clean, anti-fingerprint, anti-glare, hard, scratch-resistant, and good weather resistance. Because of its characteristics, curved glass can be applied to high-end smartphones and tablets, wearable devices, and dashboards It is widely used in terminal products such as industrial computers. Among them, the process flow of curved glass production includes: engineering, CNC cutting, profiling, hot bending, forming, double-sided polishing, cleaning, AF coating, post-coating cleaning and finished product packaging, to realize the processing and molding of curved glass. [0003] Among them, the curved glass hot bending technology is to put the existing flat glass into the hot be...
