Abstract

PURPOSE: To automatically and inexpensively produce an optical glass element excellent in optical characteristics by successively molding a glass stock in the stages of die intake, molding, die takeout and conveyance in the atmosphere of clean air blown out from a clean air blowing device.
CONSTITUTION: In the inside of a producing device 12 for an optical glass element, glass stocks are molded by sending plural pieces of molding dies 13 provided with glass stocks to be molded which are taken therein through an aperture 23 to a molding device consisting of a heating device 15, a pressing device 16 and a pressure holding device 17 from a die intake device 14 wherein the above-mentioned dies 13 are provided. Then the dies 13 are transferred to a die takeout die 18 and molded optical glass elements are taken out and carried through the above-mentioned aperture part 23. On the other hand, the dies 13 are carried into a die intake die 14 via a carrier 19. In the producing device 12, clean air 22 is blown off to the inside of a closed space 20 from a clean air blowing device 21. The glass elements free from impurities such as dust are molded by performing respective stages of the above-mentioned die intake, molding, die takeout and conveyance in the clean atmosphere formed thereby.
