Vehicle laminated glass multi-section hinge baking-bending mold and application thereof

Abstract

The present invention relates to a vehicle laminated glass multi-section hinge baking-bending mold and an application thereof. The vehicle laminated glass multi-section hinge baking-bending mold comprises a base, a fixed molding ring, an inner section molding ring, an outer section molding ring, an inner section balance force arm and an outer section balance force arm, wherein the fixed molding ring is fixed on the base, both sides of the fixed molding ring and the inner side of the inner section molding ring form hinged connections, the outer side of the inner section molding ring and the outer section molding ring form a hinged connection, the inner section molding ring is arranged on the inner section balance force arm, and the outer section molding ring is arranged on the outer section balance force arm. According to the present invention, during baking-bending molding, the inner section molding ring and the outer section molding ring completely unfold, softened glass is subjected to mold adhering and bending under a combined effect of gravity of the outer section balance force arm and the inner section balance force arm, and the glass self-weight, the outer section adjustment screw and the inner section adjustment screw respectively and slowly fall onto the outer section molding ring movement position limitation block and the inner section molding ring movement position limitation block, and the glass is baked and bends into the continuous and complete shape. Compared with the mold in the prior art, the mold of the present invention has characteristics of convenient operation, high efficiency and good quality.

Description

technical field [0001] The invention relates to a glass baking and bending mold, in particular to a multi-section hinged baking and bending mold for automobile laminated glass and its application. Background technique [0002] An existing mold for baking and bending laminated glass includes a base, a fixed forming ring and a movable forming ring. The fixed forming ring is fixed on the base, and the movable forming ring is hinged to the fixed forming ring. During the baking and bending process of large glass, the middle part of the glass is formed by a fixed forming ring, and after the glass softens, the dynamic forming circles the hinge point and gradually upwards to make the glass continuously bend and shape. [0003] In the process of producing large-arc and large-spherical glass with this structure, the forming ring of the mold can only be unfolded in a single section. If the mold is not fully unfolded, there will be glass with obvious mold traces, uncontrollable fit, and...

Problems solved by technology

[0003] In the process of producing large-arc and large-spherical glass with this structure, the forming ring of the mold can only be unfolded in a single section. If the mold is not fully unfolded, there will be glass with obvious mold traces, uncontrollable fit, and large spherical sides. It cannot be formed, and the side of the glass will have a reverse spherical surface after forming, resulting in poor optics, a large amount of waste products, and a serious impact on production efficiency
