Problems solved by technology

However, the marks left on the curved side parts are more difficult to remove
Removing this part of the imprint not only requires a more refined preparation process, but also takes much longer than the time spent on removing the imprint on the flat part, which leads to high cost and low efficiency of the post-bending process

Abstract

The invention provides a glass forming mold and a glass forming method. The glass forming mold comprises a shaping mold and a pressing mold which are matched for use; the shaping mold is provided with a shaping groove, and the bottom of the shaping groove is provided with a groove bottom plane area and a groove bottom curved surface area extending outwards in the groove opening direction along the edge of the groove bottom plane area; a pressing mold is provided with a shaping convex block, the top of the shaping convex block is provided with a convex block plane area and a convex block curved surface area, the convex block plane area is matched with the groove bottom plane area, the convex block curved surface area is matched with the groove bottom curved surface area, and when the shaping mold is matched with the pressing mold for use, the shaping convex block extends into the shaping groove; and the distance d1 between the groove bottom plane area and the protruding block plane area is 90%-99% of the thickness d of the plate glass to be processed, and the distance d2 between the groove bottom curved surface area and the protruding block curved surface area is larger than d. By adopting the glass forming mold, the subsequent processing and preparation time of the curved glass prepared by the glass forming mold can be remarkably shortened.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a glass forming mold, a glass forming device and a forming method. Background technique [0002] Portable electronic devices play an increasingly important role in today's society. Many of the many portable electronic devices in existence use glass products as their front panels or back covers. 3D curved glass can bring richer and better performance to users, and has gradually become the mainstream configuration of high-end electronic equipment, and is widely sought after by major manufacturers of portable electronic equipment and consumers. [0003] Traditional curved glass usually includes a flat part as the main body and side edges curved along the flat part. Such curved glass can be prepared by hot-bending the flat glass in a mold. Specifically, after the flat glass is cut into a predetermined shape and size, it is heated to around the softening temperature, and...
