Processing mould and processing method of inverted glass plate

Abstract

The invention provides a processing mould and a processing method of an inverted glass plate. The inverted glass plate comprises a main body part, a transitional part and a stretching part, wherein the stretching part comprises a first outer surface back away from an accommodating space; the first outer surface comprises a first end point away from the main body part and a connecting point connected with the transitional part; the first outer surface is vertical to the horizontal direction in the tangent direction of the connecting point; an included angle between the tangent direction of thefirst end point and the horizontal direction and away from the accommodating space is theta, and theta is greater than 90 degrees and equal to and smaller than 180 degrees; and the horizontal distancebetween the connecting point and the first end point is U. The processing mould comprises a lower mould with a mould cavity and an upper mould matched with the lower mould, wherein the lower mould comprises a bottom wall and a side wall which are matched to define the mould cavity; the upper mould comprises a bulge; during mould closing, the bulge stretches into the mould cavity and is spaced from the side wall; and the space between the bulge and the side wall is greater than or equal to the sum of the thickness of the stretching part and the distance U and is smaller than or equal to doubleof the sum of the thickness of the stretching part and the distance U.

Description

technical field [0001] The invention belongs to the technical field of glass forming, and in particular relates to a processing mold and a processing method for an inverted glass plate. Background technique [0002] With the development of the Internet era, more and more electronic devices have entered people's lives, such as mobile phones, tablet computers, notebooks, etc. In addition to functional requirements, people have higher and higher requirements for the appearance of electronic equipment, and more and more three-dimensional glass products are used for the housing of electronic equipment. [0003] In related technologies, glass substrate processing molds are generally used to produce three-dimensional glass products by hot bending. This kind of glass substrate processing mold usually includes a concave mold with a cavity and a convex mold matched with the concave mold. After the mold is closed, the concave mold A gap with a preset shape will be formed between the m...

Problems solved by technology

[0004] However, the glass substrate processing molds in the related art can only realize the bending process of 90° or less at the corner of the glass substrate, which limits the bending of larger angles.
