Optical lens molding device

An optical lens molding device comprising:

• a raw material supplying unit for providing a solid-state optical material which is linear or rod-shaped;
• a feeding unit disposed downstream of said raw material supplying unit in a feeding direction for transporting the solid-state optical material along the feeding direction;
• a heating unit disposed downstream of said feeding unit in the feeding direction, said heating unit including a heating body which defines a heating chamber therein, and a heating conduit which is in spatial communication with said raw material supplying unit for entering of the solid-state optical material, said heating conduit having a nozzle which serves as a downstream part and which is disposed in said heating chamber, and a heating tube which extends in the feeding direction and which projects outwardly of said heating chamber to be connected between said nozzle and said feeding unit so as to heat and melt the solid-state optical material in said heating conduit into a fluid-state optical material;
• a molding unit including at least two molds, said molds having mold surfaces which cooperatively define a cavity therebetween, and a sprue which is in communication between said cavity and said downstream part to permit the molten fluid-state optical material to be pressed by the solid-state optical material and to flow in and fill said cavity through said sprue;
• and
• a cooling unit interposed between said heating unit and said feeding unit, said cooling unit including a heat dissipating fin assembly which surrounds said heating tube, and at least one heat dissipating fan which is disposed on said heat dissipating fin assembly.
