Abstract

A thermal vacuum forming system for 3D glass is disclosed, including a rack, a thermoforming furnace chamber mechanism, a vacuum forming mechanism and a heating mold, wherein the thermoforming furnacechamber mechanism is arranged on the rack, and the vacuum forming mechanism is below the rack and is connected to the thermoforming furnace chamber mechanism to perform vacuumization. Technical effects of the system are that: a vacuum forming technique is adopted for glass panel processing, suction pressure is uniform, stress is small and a pressurization dead angle is avoided; the product yieldis effectively increased; a polishing step for subsequent 3D glass processing is omitted and various complex curved surfaces can be formed. The chamber adopts a structure having a shape like a hollowsquare which is encircled with another hollow square, and the wall of the chamber is lined with a high-temperature resistant heat insulation material, thus effectively maintaining the internal temperature of the chamber, reducing loss of heat energy and reducing energy consumption.

Description

technical field [0001] The invention relates to a 3D glass heat absorption molding system. Background technique [0002] With the introduction of new products such as mobile phones and tablet computers, the shape of the products has also changed accordingly. In order to match the shape of the products, the market has higher and higher requirements for the glass panels covering the screens. At present, the glass panels of most products Panels are required to be made of curved 3D glass. However, the existing 3D glass forming process equipment is all hot press forming equipment, and the hot press forming adopts a molding process. figure 1 As shown; the molding process requires high temperature accuracy, and temperature changes are likely to cause defective products. Moreover, the molded type is a centrally pressurized design, which may easily cause uneven force on the periphery, indentation and other defects on the concave surface of the product, which will affect the product...
