3D curved glass forming mold and forming method thereof

Abstract

The invention provides a 3D curved glass forming mold applied to the technical field of electronic display devices, and further relates to a 3D curved glass forming method, an upper mold (1) of the 3D curved glass forming mold is provided with an inclined boss I (5) and an inclined boss II (6), a movable sliding block I (3) is provided with a flat boss I (7), a movable sliding block II (4) is provided with a flat boss II (8), and the inclined boss I (5) and the inclined boss II (6) are arranged on the upper mold (1). The movable sliding block I (3) is provided with two inclined sliding grooves I (9), the movable sliding block II (4) is provided with an inclined sliding groove II (10), the lower mold (2) is provided with a glass molding part (11), the lower mold (2) is provided with a smooth sliding groove I (13), and the lower mold (2) is provided with a smooth sliding groove II (15). The hot bending forming of special-shaped, complex-structure or concave 3D curved glass products is conveniently and quickly realized, the problems of distortion, poor flatness and poor profile tolerance of a forming area in the forming process are solved, and the production efficiency is improved.

Description

Technical field [0001] The present invention belongs to the technical field of electronic display device, and more particularly to a 3D curved glass molding die, and the present invention also relates to a 3D curved glass forming method. Background technique [0002] The 3D glass molding die in the prior art is mainly simple, down-mold design (molded), which enables thermal bending-type product structure than a single, regardless, and has a more complicated product that has a concave design. . At the same time, in the process of 3D curved glass molding process, the external contour, plane and product final forming structure are affected by the design of the mold, such as the product heating. Not formed, flat, contour, and the contour can be unqualified; in addition, simple, lower mold design cannot meet structural complexity and production requirements of the concave product, and the hot bending is more difficult. Inventive content [0003] The technical problem to be solved by ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: aiming at the deficiencies of the prior art, to provide a simple structure, which can conveniently and quickly realize the hot bending of 3D curved glass products with special shape, complex structure or concave design, and ensure the production process The processing time and temperature of each part of the product are uniform, which effectively solves the problems of distortion, poor flatness, and poor contour of the forming area during the product forming process, and significantly improves the production efficiency of the 3D curved glass forming mold
