Claim:
1. A method for manufacturing a curved glass sheet, the method comprising: providing a mold and a furnace; placing the mold in the furnace, the mold comprising a first mold, a second mold located upon the first mold, and a mold core located between the first mold and the second mold, the first mold defining a receiving space, and comprising a bottom surface in the receiving space; the bottom surface in the receiving space defining at least one guiding groove, a bottom surface in the at least one guiding groove defining at least one air outlet, the mold core received in the receiving space, and supported by the bottom surface in the receiving space, the mold core defining a mold cavity and a plurality of micro-holes communicating with the mold cavity and the at least one guiding groove; placing a raw glass sheet on the second mold to cover the mold cavity; controlling a temperature in the furnace to heat the raw glass sheet to a temperature about the glass transition temperature of the raw glass sheet; extracting air in the receiving space of the mold via the at least one outlet, to force the raw glass sheet to bend until contacting a bottom surface in the mold cavity; and cooling the mold to form a curved glass sheet.
