METHOD OF MANUFACTURING MOLDED GLASS BODY

摘要

A method of manufacturing a molded glass body, wherein, in a releasing step for releasing and collecting the molded glass body from a mold after the molded glass body is molded by pressurization, the relative positions of an upper mold and a lower mold are changed to retracted positions at which the molded glass body does not drop onto the lower mold even if the molded glass body adhering to the upper mold drops from the upper mold.  Thus, even if the molded glass body adhering to the upper mold drops from the upper mold, the molded glass body does not damage the lower mold.
