An improved automobile laminated glass furnace outer pressing mold

Abstract

The invention relates to an improved mould for out-of-furnace press forming of an automobile laminated glass. The improved mold comprises a convex mold (6) and a concave mold (20). The mold is characterized in that the concave mold (20) is provided with a side pre-press forming mechanism (21) and a glass following positioning mechanism (22), the side pre-press forming mechanism (21) comprises a side pre-press cylinder (31), a pre-press rotating shaft structure (32) and a concave mold side structure (18), and the glass following positioning mechanism (22) comprises a positioner rotating shaft (24), a positioning servo motor (25), a positioning speed reducer (26), a positioning coupler (27), a transmission gear (28), a rack (29), a positioner bracket (30), a positioning cylinder (33) and a positioning stop (34). Compared with the prior art, the mold has the advantages of meeting the quality and property requirements for the molded surface, goodness of fit, optical properties of glass products with a large spherical surface, a large span, high large arch rise and great side contour curvature change, improving the yield and the like.

Description

technical field [0001] The invention relates to a mold for forming automobile glass, in particular to an improved mold for pressing and forming automobile laminated glass outside a furnace. Background technique [0002] At present, with the development of the automobile industry and the diversification of automobile shapes, the streamlined automobile shape design makes the shape of the front windshield glass of the automobile appear large spherical, large arch height, and large curvature of the side profile. During the heating and transmission process of the glass, it is easy to have a large forming position displacement (the position of the glass in the mold forming has a front-to-back deviation, a left-right deviation). When using the existing automotive laminated glass (including the front glass of the car, laminated panoramic sunroof, etc.) Its products cannot even meet the increasingly high quality requirements of automakers in terms of optical performance, fit deviati...

Problems solved by technology

[0002] At present, with the development of the automobile industry and the diversification of automobile shapes, the streamlined automobile shape design makes the shape of the front windshield glass of the automobile appear large spherical, large arch height, and large curvature of the side profile. During the heating and transmission process, it is easy to have a large forming position displacement (the glass is in the mold forming position, there is a front-to-back deviation, a left-right deviation)

When using the existing automotive laminated glass (including the front glass of the car, laminated panoramic sunroof, etc.) The products cannot even meet the increasingly high quality requirements of auto manufacturers such as optical performance and fit deviation and deviation fluctuation.
