MOLDED GLASS BODY MANUFACTURING METHOD, AND MOLDED GLASS BODY MANUFACTURING DEVICE

摘要

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.
