Manufacturing method of three-dimensional glass shell

Abstract

The invention discloses a manufacturing method of a three-dimensional glass shell, and aims to manufacture a thin three-dimensional glass shell with the arc-shaped periphery. The method comprises the following steps: 1, providing a forming heating furnace and a die, wherein the die forms a forming surface which is as same as the pre-formed surface outline of the glass shell; taking the glass shell on the die, moving the die to the forming heating furnace and heating the glass shell by short wave infrared ray, so that the forming viscosity reaches between 108 and 1,013 poises; providing a pressurizing upper die to pressurize the glass shell and stain for a preset time, so that part of the heat of the glass shell is conducted to the die, and removing the pressurizing upper die; and after the glass shell is shrunk by cooling and the die is expanded by heating until the glass shell generates rigidity and is partially separated from the die, taking the edge of the formed glass shell and removing from the die. By the method, the thin three-dimensional glass shell with the arc-shaped periphery can be manufactured.

Description

technical field [0001] The present invention relates to a method for manufacturing a three-dimensional glass case, in particular to a method for forming a thin glass case, which is used to manufacture a thin three-dimensional glass case with an arc-shaped periphery. The completed glass case of the present invention can be Applied to electronic products, the above-mentioned three-dimensional glass casing is arranged on the top surface of the electronic product and its surroundings. Background technique [0002] Currently common electronic products are usually provided with a glass casing on the surface to protect the display module inside the product. Due to the advancement of electronic product manufacturing technology, touch functions have been widely used. However, most of the current glass casings are still in the shape of a flat plate, and seams still inevitably exist around the upper surface of the electronic product. On the other hand, a mechanism with a certain widt...

Problems solved by technology

However, most of the current glass casings are still in the shape of flat plates, and there are still seams around the upper surface of electronic products.

On the other hand, a certain width of the mechanical part must be reserved around the electronic product to hold the flat glass case, so the top surface of the electronic product cannot be fully utilized, thus affecting the area where the touch function area can be set
