Embodiment Construction

[0026] Such as figure 1 and figure 2 As shown, a kind of automobile glass baking mold according to the present invention can bake and shape automobile glass or even automobile coated glass, and it includes a base 1, a forming frame 2 and two anti-weight mechanisms 3, and the forming frame 2 includes a fixed frame 21 and two movable frames 22, the fixed frame 21 is fixed on the base 1, and the two movable frames 22 are hingedly connected with the left and right ends of the fixed frame 21 respectively, and the two movable frames 22 can rotate around their respective The hinge point rotates to form a bending profile together with the fixed frame 21. The curvature of the bending profile is equal to the curvature of the final bending shape of the automobile glass. The two anti-weight mechanisms 3 are respectively fixed with the two movable frames 22. In the process of the auto glass being gradually softened by baking and bending, the anti-weight mechanism 3 can drive the movable ...

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...
