The invention discloses a processing method for a glass mold. The processing method comprises the following steps that 1, the drawing design is conducted on the glass mold, and the preparation of therequired raw materials is achieved; 2, heating melting at the temperature of 1227-1538 DEG C is conducted on the prepared raw materials, the raw materials are cooled to a metal billet, and the manufacturing environment temperature and humidity are set; and 3, mechanical-forging and forging are conducted on the metal billet in the step 2, the metal billet produces plastic deformation, then the temperature is heated to 500-550 DEG C, the annealing treatment with the insulation time of 2-8 h is conducted, and a mold billet is obtained. By means of the processing method for the glass mold, the shape of the glass mold is forged through the mechanical-forging, an inner cavity of the glass mold is processed through the shape processing and mold cavity processing, and integrated molding is achieved accordingly, the pre-pr
