Abstract

PURPOSE:To continuously produce a precise optical glass element through a short duct by passing a molding block wherein a glass stock is packed in both a forming mold and a drum mold through a heating device and also adding force to the forming mold from the outside of the heating device. CONSTITUTION:A molding block 10 is obtained by packing a glass stock 1 among the upper and lower molds 3, 2 are a drum mold 4 which have functional surfaces of optical precision. Then this block 10 is carried to the direction shown by the arrow A via the conveyer 7 of a carrier 11 and introduced into a heating part 12 maintained in the nonoxidative atmosphere by inert gas or reducing gas introduced through a gas intake 18. After arranging a weight 5 in a inlet 13 so that force is exerted to the molding direction of the mold, the block 10 is pressurized and molded while allowing the weight 5 and the block 10 to be passed via inlets 13, 16 through the heating part 12 previously set so that required temp. gradient is held and thereafter taken out through outlets 14, 17.
