Improved mold for out-of-furnace press forming of automobile laminated glass

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 present invention relates to an automobile glass forming mould, in particular to an improved outer pressing forming mould for automobile laminated glass. 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 of the automobile appear large spherical, large arched, and the curvature of the side profile changes greatly. During the heating transmission process, it is easy to have a large molding position shift (the glass has a front and rear deviation in the molding position of the mold, and a left and right deviation). When using the existing automotive laminated glass (including automobile front windshield, laminated panoramic sunroof, etc.) to press molding molds to produce this type of glass, it is easy to produce side refraction and wave quality defects, which makes the yield of such prod...

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.
