Molding device for 3D curved glass

Abstract

The invention discloses a molding device for 3D curved glass. The device includes a lower mold base and a curved concave cavity, and the lower mold base is provided with the curved concave cavity; anda vacuum hole is arranged in the middle position of the bottom wall of the curved concave cavity, the lower mold base is provided with a No.1 channel communicating with the vacuum hole, one end, faraway from the vacuum hole, of the No.1 channel is provided with a No.1 connecting pipe, the No.1 connecting pipe is connected to a No.1 vacuum pipe through a No.1 two-way joint, a vacuum groove is arranged in the curved concave cavity, and the lower mold base is provided with a No.2 channel communicating with the vacuum groove, one end, far away from the vacuum groove, of the No.2 channel is provided with a No.2 connecting pipe, and the No.2 connecting pipe is connected with a No.2 vacuum pipe through a No.2 two-way joint. By adopting the technical solution, the device facilitates improving quality of the heat-molded curved glass, effectively reduces the phenomenon of a poor appearance, and has a good molding effect.

Description

technical field [0001] The invention relates to the technical field of 3D curved glass processing, in particular to a 3D curved glass forming device. Background technique [0002] The performance of 3D curved glass is light and thin, transparent and clean, anti-fingerprint, anti-glare, hard, scratch-resistant, and good weather resistance. Panel protection glass for terminal products such as industrial computers. During the forming process of 3D curved glass, the glass is placed in the curved cavity of the lower mold base, and the glass is heated and softened in the curved cavity through the co-extrusion of the upper mold base, but the existing glass is in the lower mold base. The molding positioning in the curved surface concave cavity is poor, and the fluidity of the glass material is also enhanced as the glass is heated and softened. Although this will make the contour deviation of the curved glass plate after molding smaller, its appearance will be poor. Therefore, We d...

During the forming process of 3D curved glass, the glass is placed in the curved cavity of the lower mold base, and the glass is heated and softened in the curved cavity through the co-extrusion of the upper mold base, but the existing glass is in the lower mold base. The molding positioning in the curved surface concave cavity is poor, and the fluidity of the glass material is also enhanced as the glass is heated and softened. Although this will make the contour deviation of the curved glass plate after molding smaller, its appearance will be poor. Therefore, We design a 3D curved glass forming device
