glass gob molding device, method of manufacturing a glass gob, and glass moldings method of manufacturing

摘要

The glass gob molding apparatus (1) comprises a glass forming mold (102) having a plurality of through-holes (102a) to have formed recesses forming surface (102e), gas delivered from the predetermined gas supply unit is plural via a gas passage communicating with the through-hole (102a) in a state of being ejected from the plurality of through holes, and receiving the molten glass to be supplied to the concave portion forming surface (102e), is formed into a glass gob having a predetermined shape. Through holes (102a), the molten glass is, when it is supplied to the recess forming surface (102e), has a inhibiting buffer (102ab) the variation in the flow rate of the gas ejected from the through holes (102a) . The glass gob molding machine (1), it is possible to stably levitate the molten glass.
