Embodiment 1

[0025] Embodiment 1: A solid mold for tempered glass molding, which is made by the following steps: ① Spread three layers of glass cloth on the inner surface of the curved tempered glass as convex glass cloth 1; Add a circle of steel bars 2 where the distance h between the inner surface of 1 and the edge of the glass cloth is 100 mm; ③ After adding the steel bars, lay three layers of glass cloth on the steel bars as the concave glass cloth 3; ④ On the inner surface of the concave glass cloth 3 After applying the styling liquid, let it dry for 30 minutes at room temperature. Five fixing modules 4 are also arranged on the inner surface of the concave glass cloth.

[0026] The styling liquid is prepared by mixing the following raw materials in parts by weight: 3 g of 191 unsaturated polyester resin, 0.5 g of benzoyl peroxide, 1.5 g of ketone, and 5 g of isophthalic gel coat.

Embodiment 2

[0027] Embodiment 2: A solid mold for tempered glass molding, which is made by the following steps: ① Spread two layers of glass cloth on the inner surface of the curved tempered glass as convex glass cloth 1; Add a circle of steel bars 2 at the distance h between the inner surface of 1 and the edge of the glass cloth at a distance of 90 mm; ③ After adding the steel bars, lay two layers of glass cloth on the steel bars as the concave glass cloth 3; ④ On the inner surface of the concave glass cloth 3 After applying the styling liquid, dry it at room temperature for 25 minutes. Four fixing modules 4 are also arranged on the inner surface of the concave glass cloth.

[0028] The styling solution is prepared by mixing the following raw materials in parts by weight: 2.5 g of 191 unsaturated polyester resin, 0.7 g of cumin hydroperoxide, 1.2 g of ketone, and 5.5 g of isophthalic gel coat.

Embodiment 3

[0029] Embodiment 3: A solid mold for tempered glass molding, which is made by the following steps: ① Spread a layer of glass silk cloth on the inner surface of the curved tempered glass as convex glass cloth 1; Add a circle of steel bars 2 where the distance h between the inner surface of 1 and the edge of the glass cloth is 110 mm; ③ After adding the steel bars, lay three layers of glass cloth on the steel bars as the concave glass cloth 3; ④ On the inner surface of the concave glass cloth 3 After applying the styling solution, dry it at room temperature for 35 minutes. Six fixing modules 4 are also arranged on the inner surface of the concave glass cloth.

[0030] The styling liquid is prepared by mixing the following raw materials in parts by weight: 3.5 g of 191 unsaturated polyester resin, 0.3 g of di-tert-butyl peroxide, 1.7 g of ketone, and 4.5 g of isophthalic gel coat.

Abstract

The invention discloses a solid mold for tempering glass molding, and particularly relates to a solid mold for curved tempered glass molding. The invention aims to solve the technical problems of difficult molding, low yield and poor appearance quality of curved tempering glass. The mold is prepared through the following steps: 1, covering at least one layer of glass fiber on the inner surface of the curved glass as a convex glass wool cloth; 2, adding a lap of steel bar on the inner surface of the convex glass wool cloth; 3, paving at least one layer of glass wool cloth on the steel bar as a concave glass wool cloth; and 4, coating a fixing liquid on the inner surface of the concave glass wool cloth and drying at room temperature for 25-35 min. Adopting the technical scheme, the self-destruction rate of the curved tempering glass is reduced from 1% to 0.3%.

Description

technical field [0001] The invention relates to a solid mold, in particular to a solid mold for forming tempered glass with arcs. Background technique [0002] In recent years, tempered glass has been widely used in various industries due to its safety and surface strength exceeding other types of glass, providing a strong security guarantee for various industries. However, in the automotive glass processing industry, due to the design of the car body, many OEMs pursue the roundness and aesthetics of the car basket, resulting in a lot of rear windshields with excessive curvature, which increases the difficulty of the glass manufacturing process, and makes the belt Curved tempered glass molding and after-sales self-explosion problems have become the biggest problems in the industry. At the same time, it has caused a lot of after-sales losses to the company and has also caused a great impact on customers. All curved tempered glass is made of a single steel bar. Molding moldin...
