[0056] see figure 1 , the present embodiment provides a mold 100 for forging and absorbing compositely shaped glass surface textures, which is used to shape the three-dimensional textures of glass. The mold 100 for forming glass surface texture by forging and absorbing compositely includes an upper mold 110 and a lower mold 120, wherein the upper mold 110 is a concave mold, and the lower mold 120 is a convex mold. see figure 2 , the lower mold 120 is made of graphite, the upper surface of the lower mold 120 is a molding surface, and the molding surface is provided with diamond or wavy textures, and the raised ridgeline design and processing edge R angle of the surface texture of the lower mold 120 are less than or Equal to 0.1mm. The lower mold 120 has air holes, and the gas above the lower mold 120 can reach the bottom of the lower mold 120 through the air holes. In this way, after the upper mold 110 and the lower mold 120 are pressed together, air holes on the lower mold...

[0069] see Figure 4 , this embodiment provides a method for forging and absorbing compound glass surface texture, which is mainly realized by using the mold 100 for forging and absorbing compound forming glass surface texture provided in the first embodiment and the system for forging and absorbing compound forming glass surface texture, specifically including The following steps:

[0070] S1: Pre-press the glass into a bent shape.

[0071] Pre-pressing into a bent shape means that the glass is processed by a hot-bending process. First, the glass is heated to about 700°C, and then the glass is hot-pressed through the upper mold 110 and the lower mold 120 to form a glass with curved surface characteristics.

[0072] S2: Perform forging-suction composite molding on the pre-pressed glass, wherein the upper mold 110 performs forging and pressing on the glass, and the lower mold 120 and the glass perform vacuum adsorption.

[0073] Both the upper mold 110 and the lower mold 120 ...

Abstract

The invention provides a method, a mold and a system for forging-adsorption composite molding of surface textures of glass, belonging to the technical field of 3D glass molding. The method provided by the invention comprises the following steps: pre-pressing glass into a bent shape; and conducting forging-adsorption composite molding on the pre-pressed glass, wherein the glass is forged and pressed through an upper die, and vacuumizing adsorption is conducted between a lower die and the glass. The method can ensure that the ridge of a texture area of a product is clear, and meanwhile, an appearance surface is almost free of mold printing transfer.

Description

technical field [0001] The invention relates to the technical field of 3D glass forming, in particular to a method, a mold and a system for forging and absorbing compositely formed glass surface textures. Background technique [0002] At present, conventional 3D glass forming is mainly realized by hot pressing process, including hot bending and hot forging process. Ordinary 3D glass is formed by hot pressing of graphite mold at a temperature of about 700°C. This common hot pressing forming forms 3D glass. The process of curved glass is also called hot bending. [0003] The forming temperature of the existing hot bending process is low, and the ridge line in the texture area of ​​the product is not clear. Due to the high temperature and pressure of the hot forging process, although it can form a straight ridge line effect, it is easy to produce serious mold marks on the product surface Transcription, it takes a long time to polish to remove, and the amount of polishing remov...
