A kind of automobile glass baking and bending mold

Abstract

The invention relates to the field of heat-bending molding technology for glass, especially to a heat-bending die capable of carrying out heat-bending molding on automotive glass, particularly to the automotive glass heat-bending die capable of carrying out heat-bending molding on coated glass with a surface nanometer coating. The automotive glass heat-bending die comprises a base, a molding frame and two antigravity mechanisms. An auxiliary heating device is additionally and correspondingly installed above each movable frame; and each auxiliary heating device comprises two first vertical rods, two rotation transmission rods, two second vertical rods, two fixed bases and a plurality of auxiliary heating elements. According to the invention, the additionally installed auxiliary heating elements are allowed to be synchronized with the heat-bending and softening process of the automotive glass, heat flux needed in heat-bending molding of the automotive glass can be guaranteed, and transition of the arc contour of the heat-bending molded automotive glass is allowed to be smoother; moreover, the nanometer coating of the coated glass can be protected and is prevented from damage by unstable heat flux during heat-bending molding of the automotive glass.

Description

[0001] Technical field: [0002] The invention relates to the technical field of glass baking and bending, in particular to a baking and bending mold capable of baking and forming automobile glass, especially an automobile glass baking and bending mold capable of baking and forming coated glass with a nano-coating on its surface . [0003] Background technique: [0004] Usually, the process steps of baking and bending a glass plate are as follows: placing the glass plate on a baking mold that matches the final shape of the glass plate, and then transporting it into the bending furnace together, and heating the glass plate in the bending furnace. As the temperature of the glass plate rises gradually, the viscosity of the glass plate will gradually decrease and become soft. The softened glass plate will gradually fit on the bending mold, and finally will form a shape that is basically the same as the bending mold to obtain the bent glass. plate. When the glass plate is heated a...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is that the arc profile of the baked-bending glass is not smooth enough in the above-mentioned prior art, the distance between the heating element and the glass surface is still changing during the bending and deformation of the glass, or the heating element is unstable when lifted and lowered. The disadvantages such as decreased airtightness are provided, and an automobile glass baking and bending mold is provided
