Cooling system in 3D (three dimensional) curved glass hot pressing device and cooling method

Abstract

The invention discloses a cooling system in a 3D (three dimensional) curved glass hot pressing device and a cooling method. An apparatus comprises a molding chamber, a first cooling module and a liquid cooling passage, wherein the first cooling module penetrates through the molding chamber and is used for cooling a molded product in a heat transferring manner and also stably maintaining the pressure; and the liquid cooling passage is communicated with the molding chamber and used for continuously cooling the stably-pressure-maintained molded product. By adopting the cooling system in the 3D curved glass hot pressing device provided by the invention, after the molded product is stably pressure maintained by the first cooling module, the molded product can be continuously cooled by virtue of the liquid cooling passage, so that after 3D curved glass of a smart phone is molded by adopting the hot pressing device, the problem of product cracking caused by the sharply-cooling of a liquid cooling plate can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of hot pressing equipment, in particular to a cooling system and a cooling method in hot pressing equipment for 3D curved glass. Background technique [0002] With the development of smartphones, in addition to Samsung and LG launching smartphones with curved screens, smartphones like Apple’s use more non-planar glass with rounded edges, that is, the middle area of ​​the glass is flat and the edges are flat. A curved surface is used for the transition, and the above-mentioned non-planar glasses all belong to the scope and application scope of the smart phone 3D curved glass of the present invention. [0003] Because the processing of 3D curved glass is difficult and the process route is relatively complicated, the existing non-flat glass generally adopts cold processing, that is, the edge of flat glass is ground and polished to obtain the required curved edge; however, This cold processing method is easy to...
