Title: GLASS GOB MOLDING DEVICE, METHOD FOR PRODUCING GLASS GOB, AND METHOD FOR PRODUCING GLASS MOLDED PRODUCT
Abstract:
This glass gob molding device (1) comprises a glass molding mold (102) having a recessed molding surface (102e) in which a plurality of through holes (102a) are formed, the glass gob molding device molding a glass gob having a predetermined shape by receiving molten glass, which is supplied onto the recessed molding surface (102e), in a state where a gas that is sent out from a predetermined gas supply unit blows out from the plurality of through holes (102a) via a gas flow path that is in communication with the through holes. The through holes (102a) are provided with buffer parts (102ab) that inhibit fluctuations in the amount of flow of the gas blowing out from the through holes (102a) when the molten glass is supplied onto the recessed molding surface (102e). With this glass gob molding device (1), it is possible to make the molten glass float stably.
