Abstract

Provided is a molded glass body manufacturing method which suppresses temperature distribution nonuniformity in the glass material and the mold unit in press processing. This molded glass body manufacturing method involves a heating step in which a glass material is heat processed in a heating chamber by means of a heater, a first and second press step in which the glass material is press-processed in a first and second press chamber while being heated by means of a heater, and a gradual cooling step in which the temperature of the molded body which has completed press processing is lowered in a first and second gradual cooling chamber while being adjusted by means of a heater, wherein in the first and second press steps, the glass material is press-processed twice, and between the two press processings, a mold unit (8) is rotated such that the angular position relative to the conveyance path of the mold unit (8) changes.

Description

technical field [0001] The present invention relates to the manufacturing method of glass forming body and the manufacturing device of glass forming body, particularly relate to the manufacturing device of the glass forming body that is provided with heater on both sides of the conveying path of heating chamber, molding chamber and slow cooling chamber, and use this to make A method of manufacturing a glass molded body of a device. Background technique [0002] In recent years, glass moldings such as lenses have been manufactured using equipment that places glass material in a mold, heats the glass material and the mold, and press-moldes the softened glass material through the mold to manufacture a glass molding. As a manufacturing device of such a glass molding, for example, in Patent Document 1 (Japanese Patent Publication No. 7-29779), a manufacturing device of a glass molding is disclosed: a heating chamber, a molding chamber, and a slow cooling chamber are arranged in a...
