Automobile glass forming die and production method thereof

Abstract

The invention relates to an automobile glass forming die which comprises an upper male die, a lower female die and a control system; the outer convex face of the upper male die corresponds to the outer concave face of the lower female die, the lower female die is used for bearing a plurality of glass plates, the upper male die comprises a plurality of vacuum holes, and the plurality of vacuum holes are formed in the edge of the outer convex face of the upper male die in a surrounding mode; and a plurality of vacuum holes penetrate through the interior of the upper convex die to the outer convex face of the upper convex die. When the outer convex face of the upper convex die is attached to the glass plates, the plurality of vacuum holes can be overlapped with the glass plates, and the overlapping area of the plurality of vacuum holes and the glass plates is 1.5%-4.5% of the area of the glass plates; and the control system is communicated with the middle part of the outer convex face of the upper convex die and the edge part of the outer convex face of the upper convex die at the same time, and the control system can drive the upper convex die to adsorb the plurality of glass plates located on the lower concave die at the same time. According to the automobile glass forming mold, the overall optical quality and the overall molded surface of the glass plates are improved, the overall molded surface fluctuation of the glass plates is reduced, and the production requirement of large-batch glass plates can be met.

Description

Technical field: [0001] The invention relates to the field of manufacturing molds, in particular to a forming mold and a production method suitable for manufacturing automobile laminated glass. Background technique: [0002] With the development of the automobile industry, automobile OEMs have an increasing demand for laminated front glass with complex shape, large curvature and light weight; out of consideration for vehicle appearance, driving safety and fuel economy, sandwich front glass Glass manufacturing requirements are increasing day by day, and there are higher requirements for the production process and molding equipment of the laminated front windshield; the current manufacturing process of the laminated front windshield includes a step-by-step pressing molding process, the specific steps of which are to first put the glass The plate is placed on the forming mold, and the glass plate is heated to the softening temperature so that the glass plate is attached to the ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing curved glass plate device cannot uniformly and stably press the laminated glass, the production consistency is poor, and it is impossible to simultaneously The synchronous adsorption of multiple glass plates cannot meet the defects of mass production. It provides a method that can simultaneously absorb multiple pieces of laminated glass during the pressing process, and can adjust the degree of pressing of the glass plates according to the actual production situation. Automobile glass forming mold for uniform and stable pressing and improving the overall optical quality of the glass plate
