Abstract
The invention provides a multi-curved glass forming method. The multi-curved glass forming method comprises the following steps that a forming furnace comprises a conveying mechanism, an interaction area, a heating area, a forming area and a cooling area; a plurality of molds are placed in each functional area, are made of porous materials and are provided with grooves or bosses for profiling theouter surface of multi-curved glass; a glass substrate is fed to the molds in the interaction area through the interaction area; the heating area heats the glass substrate to reach a set temperature;the glass substrate is continuously heated in the forming area; an air exhauster communicates with the forming area to vacuumize the forming area, so that gas penetrates through through holes of the molds to enter the air exhauster; the cooling area cools the glass substrate to obtain multi-curved glass; and the multi-curved glass is taken out of the molds in the cooling area. Gas is exhausted from the through holes of the molds, exhaust is uniform, the through holes are tiny holes, no through hole trace is left when the glass substrate is formed, and thus the surface quality of multi-curved glass forming is improved.
