Hot bending die and hot bending equipment

Abstract

The invention provides a hot bending die and hot bending equipment, wherein the hot bending die is used for hot bending to-be-processed glass, and the hot bending die comprises a first die and a second die; the first die is provided with at least one cavity, a cavity bent surface is arranged in the cavity, and the cavity bent surface comprises a first plane and a first curved surface which are connected; the normal direction of the first plane intersects with the thickness direction of the first die, the second die and the first die are oppositely arranged, at least one protruding block is arranged on the side, facing the first die, of the second die, and the protruding block is provided with a protruding block bent face; and the protruding block bent surface and the cavity bent surface are respectively pressed on two opposite sides of to-be-processed glass during hot bending and guide the to-be-processed glass to be bent. According to the hot bending die provided by the invention, the internal stress of the whole to-be-processed glass is relatively uniform, so that the phenomenon that the to-be-processed glass deviates due to non-uniform stress is avoided, and the forming quality of the processed to-be-processed glass with the bent surface is improved.

Description

technical field [0001] The application relates to the technical field of mold processing, in particular to hot bending molds and hot bending equipment. Background technique [0002] With the rapid development of 3D curved glass technology, the application of 3D curved glass in various industries is increasing. The glass to be processed is prone to problems such as uneven stress on the product during the hot bending process, so how to effectively avoid the problem of uneven force on the product to be processed during the hot bending process, and improve the quality of the glass to be processed The molding yield rate becomes a technical problem that needs to be solved. Contents of the invention [0003] This application provides a hot bending mold and hot bending equipment that can effectively avoid problems such as uneven stress on the product to be processed during the hot bending process and increase the yield rate of the glass to be processed. [0004] In the first asp...
