The invention provides a curved glass manufacturing method for a glass hot-bending machine. The curved glass manufacturing method includes the steps of heating pretreatment, heating pre-compression treatment, cooling compression treatment and cooling decompression treatment. The heating pretreatment step includes heating a graphite die to a first set temperature by a plurality of heating stations;the heating pre-compression treatment step includes heating the graphite die to a second set temperature by at least two pre-forming stations, and compressing the graphite die to a first set pressure; the cooling compression treatment step includes compressing the graphite die to a second set pressure by a plurality of forming stations, and cooling the graphite die to a third set temperature; thecooling decompression treatment step includes cooling and decompressing the graphite die by a plurality of annealing stations. The curved glass manufacturing method for the glass hot-bending machineis provided with a plurality of heating stations, time setting of a single heating station is shortened, and productivity is improved under the condition of ensuring quality of glass products.
