Problems solved by technology

However, since graphite hot-pressing molds need to realize upper and lower mold clamping and mold opening, the bending angle of the produced curved glass is generally less than 70°, and glass shapes greater than 90° cannot be processed
Therefore, the glass hot bending forming method at this stage still needs to be improved.

Abstract

The invention puts forward a hot-pressing die, a curved glass hot-press molding method and application thereof. The hot-pressing die comprises a convex die and a concave die. The convex die is provided with a lug boss, which comprises a first plane portion and a first curved portion. The concave die is provided with a concave part, which cooperates with the lug boss. The concave part comprises a second plane portion and a second curved portion. The first curved portion is provided with multiple air-vents. By arranging the multiple air-vents on the curved portion of the lug boss of the convex die, high pressure gas can be introduced through the convex die in the hot-press molding process of plane glass. Thereby, softened glass is attached to the surface of the concave die, and it is furthergood for demoulding of wide-angle curved glass.

Description

technical field [0001] The present application relates to the technical field of electronic equipment and its manufacture, and in particular to a hot pressing mold, a casing of an electronic equipment and the electronic equipment. Background technique [0002] The current glass hot-bending forming method is generally to first heat the flat glass to the softening temperature, and then apply a certain pressure through the upper mold of the graphite mold to bend the glass into a certain shape. However, since graphite hot-pressing molds need to be clamped and opened up and down, the bending angle of the produced curved glass is generally less than 70°, and glass forms larger than 90° cannot be processed. Therefore, the glass hot bending forming method at this stage still needs to be improved. Contents of the invention [0003] An object of the embodiments of the present application is to provide a hot-pressing mold for curved glass, a method for hot-pressing curved glass usin...
