Glass plate processing method and glass plate processing mold

Abstract

The embodiment of the invention relates to the product forming field, and discloses a glass plate processing method. The glass plate processing method includes: providing a pre-forming die, which comprises a first female die and a first male die; providing a glass plate, and performing hot-pressing on the glass plate to form prefabricated glass, i.e. conducting hot-pressing on the glass plate by the first male die, and pressing the glass plate into the first female die to form the prefabricated glass, which consists of a main body part and a first bending part; providing a forming die, which comprises a second female die and a second male die; and conducting hot-pressing on the prefabricated glass to form a finished glass product, i.e. making the first bending part and part of the main body part close to the first bending part form a second bending part, bending and extending the second bending part in a direction far from a second mold core, and then bending and extending the second bending part reversely in a direction close to the second mold core. The embodiment of the invention further provides a glass plate processing mold, the method and the mold can be used for forming a three-dimensional glass product with a back-off structure, the mold design is simple, and the requirements for the space and function of an operation machine are low.

Description

technical field [0001] The embodiments of the present invention relate to the field of product molding, and in particular to a glass plate processing method and a glass plate processing mold. 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. In the prior art, a glass plate processing mold is generally used to produce three-dimensional glass products by hot pressing. The glass plate processing mold usually includes a concave mold with a cavity and a convex mold matched with the concave mold, and the glass plate to be processed It is sandwiched between the concave mold and the convex mold. At high temperature, the...

Problems solved by technology

[0003] The inventors of the present invention found that: based on aesthetic design and the pursuit of art, more and more three-dimensional glass products are designed with undercut structures. However, general convex and concave molds cannot realize the formation of undercut structures, but A mold with a row structure is required to realize it. The design of the mold with a row structure is complicated, and the space and function requirements of the operating machine are also high, which is not conducive to the production of three-dimensional glass products with an inverted structure.
