Abstract
An optical lens forming mold comprises a first mold core and a second mold core. Moreover, the first mold core has a first mold core surface, and the second mold core has a second mold core surface and a cavity corresponding to the first mold core surface. In the process of molding, flowing speed of the glass material can be controlled by the difference of roughness between the first mold core surface and the second mold core surface, or the difference of the friction relative to the glass material between the first mold core surface and the second mold core surface. Therefore, the shape of the glass lens that is conforming to demand can be molded. By the use of the optical lens forming mold, we can simplify the process, lower the cost of the forming material, reduce the manufacturing time, and then save the manufacture cost of the optical lens.
