Embodiment Construction

[0025] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, in the production process of pressing outside the glass furnace, a heating furnace 103 is installed on the production line. The heating furnace is mainly used to heat and soften the glass plate to prepare for the next step of bending. The glass plate 101 is transported through the horizontal conveying roller table 102. Overheating furnace 103.

[0027] After being heated by the heating furnace 103, the glass plate 101 reaches the softening temperature and is transported into the forming area 104 through the horizontal conveying roller table 102. The forming area 104 is provided with a pressing punch 105 and a pressing die 106. When the glass plate 101 approaches the pressing die When 106 is directly above, the pressing die 106 rises rapidly and holds up the softened glass plate 101 and presses against the pressing punch...

Abstract

The invention relates to a pressing mold used for bending a glass plate which is softened by heating, and especially relates to a resin mold used for molding a glass plate by pressing outside a furnace. The resin mold comprises a male mold. The male mold comprises a flange joint, an upper cover plate, a side plate and a molding plate. A molding resin layer with a same shape with the molding plateis arranged on a convex surface of the molding plate of the male mold. A plurality of vacuum through holes which penetrate through the molding plate and the molding resin layer, and communicate with a vacuum chamber, are arranged in the molding resin layer. According to the invention, a development period of the resin mold is greatly reduced, the production cost is greatly reduced, and the resin mold can be used for stable and continuous production for a long term. With the resin mold provided by the invention, a trend of automobile glass diversification can be satisfied, the cost in developing and producing can be reduced, and the overall quality of the products can be ensured.

Description

technical field [0001] The invention relates to a pressing mold for bending heated and softened glass plates, in particular to a resin mold for pressing glass plates out of a furnace. Background technique [0002] The front windshield glass, side window glass and rear windshield glass on the car are all bent and shaped glass. Ordinary flat glass must be heated and softened and then bent into a specific shape before it can be accurately installed into the specified car body frame; At the same time, the bent glass must also undergo strict optical inspection to ensure that there is no optical distortion, and any defects on the press molding mold used for bending flat glass may cause optical distortion of the product, so the press molding mold not only needs to meet Product-specific shape and curvature requirements, but also need to ensure that the optical quality of the product will not be affected. [0003] To bend ordinary flat glass into a specified shape, there are general...
