摘要： A method for manufacturing curved glass sheet includes the following: an equipment, including a matching first mold core and a second mold core, is provided; a raw glass sheet is provided and placed on the second mold core covering second mold cavity; a pressure is controlled in the first and second mold cavities to a first pressure; the mold cores are closed and heated, to raise the raw glass sheet to a temperature of about glass transition temperature of raw glass sheet; a gas is supplied into the first mold cavity to raise the pressure in the first mold cavity to a second pressure which is greater than first pressure, in which the raw glass sheet is bent to the second forming surface of second mold core under pressure; mold cores are opened and cooled down to obtain the curved glass sheet.
