Problems solved by technology

The mold extrusion molding method is used. Since the mold needs to be in contact with the upper and lower surfaces of the glass plate blank during molding, the concave surface and convex surface of the curved glass after molding have greater roughness and more surface defects.

Embodiment Construction

[0017] see figure 1 and figure 2 , in the curved glass forming method of the embodiment of the present invention, the glass plate blank 200 (such as Figure 4 ) shaped into curved glass 300 (eg Figure 6 ). The mold 100 includes a lower mold 10 , an upper mold 30 opposite to the lower mold 10 , and a mold core 50 disposed between the lower mold 10 and the upper mold 30 .

[0018] The lower mold 10 is roughly a cuboid and includes a mounting surface 11 close to the mold core 50 . The mounting surface 11 is recessed inward to form a receiving space 111 suitable for the mold core 50 to accommodate the mold core 50 . The lower mold 10 includes a bottom surface 113 for supporting the core 50 . The bottom surface 113 is recessed to form a plurality of diversion grooves 115 distributed at intervals. The bottom surface 117 of each diversion groove 115 is provided with an exhaust port 119 . The exhaust port 119 communicates with the receiving space 111 . In this embodiment, ther...

Abstract

A mold includes a first mold, an second mold located upon the first mold, and a mold core located between the first mold and the second mold. The first mold defines a receiving space, and comprises a bottom surface in the receiving space. The bottom surface in the receiving space defines at least one guiding groove. A bottom surface in the at least one guiding groove defines at least one air outlet. The mold core is received in the receiving space and supported by the bottom surface in the receiving space. The mold core defines a mold cavity and a plurality of micro-holes communicating with the mold cavity and the at least one guiding groove.

Description

technical field [0001] The invention relates to a glass molding method, in particular to a molding method for curved glass and a mold used therefor. Background technique [0002] In recent years, in order to make the display panels of electronic devices more fashionable, the industry has attempted to apply curved glass to the display panels. The forming method of curved glass generally adopts the gravity bending method, that is, the glass plate blank is heated to its glass transition temperature or higher than its glass transition temperature, and then the heated glass plate blank is transported to the forming mold of the forming furnace, and the forming mold There is a concave forming surface, and the glass plate blank depends on its own gravity to make it sag and bend to the concave forming surface, thereby forming a curved glass. However, since the gravity bending method uses the gravity of the glass itself to sag and bend, the profile error of the curved glass is relati...
