Glass cover plate hot bending die and hot bending preparation system and process of glass cover plate

Abstract

The invention provides a glass cover plate hot bending die and a hot bending preparation system and process of a glass cover plate.The glass cover plate to be processed is provided, the glass cover plate hot bending die comprises a lower die body, a cavity and four or more glass balls, the cavity is formed in the lower die body, the four glass balls are evenly distributed between the cavity and the lower die body, the glass cover plate to be processed is arranged on the cavity, and when the glass cover plate hot bending die is heated to be close to and lower than the lowest softening temperature of the glass cover plate to be processed, the glass cover plate to be processed and the glass balls are softened and deformed after being pressed.Due to the arrangement of the glass balls, the action of force originally exerted on the glass cover plate to be processed is dispersed evenly, so that the problem that the local area of the glass cover plate to be processed is uneven or concentrate in stress due to excessively large pressure is reduced.

Description

【Technical field】 [0001] The invention relates to the field of glass cover plate preparation, in particular to a glass cover plate hot bending mold, a glass cover plate hot bending preparation system and a process thereof. 【Background technique】 [0002] The glass cover is the protective glass. With the upgrading of product requirements, the market has higher and higher requirements for glass screens. At present, the market generally divides glass dry plates into flat glass cover plates and non-planar glass cover plates. Among them, the middle area of ​​the non-planar glass cover plate can be a plane or a curved surface, and the edge part of the glass cover plate uses arc transition. The advantage of the non-planar glass cover is that it greatly improves the appearance of the mobile phone and improves the user's experience when using the screen touch screen. put forward higher requirements. [0003] The existing non-planar glass cover is generally prepared by cold process...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defects of the current non-planar glass cover plate preparation, the present invention provides a glass cover plate hot-bending mold with easy operation and high product quality stability, a glass cover plate hot-bending preparation system and its process
