Method and mold for manufacturing curved glass sheet
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.
