Abstract

The invention provides a manufacturing method of a hot-bent mobile phone glass cover plate. The manufacturing method comprises steps as follows: a glass workpiece is subjected to preheated forming, and the glass workpiece after preheated preforming is subjected to hot pressing and first heat absorption; the glass workpiece is subjected to second heat absorption; the glass workpiece after the second heat absorption is subjected to pressure maintaining; the glass workpiece after pressure maintaining is cooled, and the mobile phone glass cover plate is manufactured. The heat absorption process isadded during hot bending of the glass workpiece, hot pressing and first heat absorption are performed simultaneously when the mobile phone glass cover plate is almost formed, then, second heat absorption is performed, the glass workpiece is completely adsorbed on a cavity surface of a die, so that the form of the formed mobile phone glass cover plate can be consistent with drawing, the surface profile is better, tooling marks on the formed mobile phone glass cover plate are reduced, time for the following forming procedure is saved, and the forming efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of forming a 3D curved glass cover plate, in particular to a method for manufacturing a glass cover plate of a hot curved mobile phone. Background technique [0002] In the prior art, the glass workpiece needs to go through preheating, hot pressing, pressure holding and cooling processes in sequence during hot bending, and the mobile phone glass cover is formed by pressure. However, the products formed in this way have more molds, which is easy to cause product The defect rate increased. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a method for manufacturing a glass cover plate of a hot-bent mobile phone, which solves the problem that the existing glass workpiece has many stamps and is easy to Technical problems that cause an increase in the defective rate of products. [0004] The present invention adopts fol...
