METHOD FOR MANUFACTURING GLASS MOLDING

摘要

A method for manufacturing a glass molding using a molding device (100) comprises: a step of feeding molten glass (82) onto the upper surface of a holding member (20) from an outflow nozzle (12) in a state in which an opening/closing part (25) is closed, and forming a glass gob on the inside of a drip pan ring (30); a step of dropping the glass gob by opening the opening/closing part (25) when the glass gob has reached a predetermined quantity; and a step of press-molding the glass gob using a lower die (60) and an upper die (70); a vibration-generating device (40) causing the drip pan ring (30) to vibrate at a predetermined frequency in the step of feeding the molten glass (82) onto the upper surface of the holding member (20) from the outflow nozzle (12). A high-quality glass gob is formed, and a high-precision glass molding is obtained.
