GLASS GOB MOLDING APPARATUS, GLASS GOB PRODUCTION METHOD, AND METHOD FOR PRODUCTION OF OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a glass gob molding apparatus for molding glass using a plurality of molds while floating the glass in a stable condition.;SOLUTION: There are provided the two types of glass gob molding apparatuses comprising supplying molten glass to a mold and molding into a glass gob while floating the molten glass by making a gas eject from the mold and applying wind pressure. The apparatus (1) is provided with a plurality of molds, a gas supply mechanism for supplying the gas for application of wind pressure, and the gas flow path for feeding the gas from the above mechanism to each mold. Further, the apparatus has in the gas flow path, a buffering mechanism for controlling the fluctuation of gas ejection amount in the mold caused by the pressure fluctuation in the gas ejection holes of the other molds. The apparatus (2) is provided with the plurality of molds and the gas supply mechanisms which are independently provided for every molds.;COPYRIGHT: (C)2007,JPO&INPIT
