AI Technical Summary

Problems solved by technology

In particular, when the molten glass is supplied by intermittent melting, since the raw material glass is not continuously melted, air bubbles, streaks, etc., or devitrification tend to occur, which causes the optical properties of the glass preform to be unstable.

Abstract

The invention provides the device and method for manufacturing glass shaping product by melting raw materials. The glass shaping product manufacturing device 10 comprises: fusing device 100, having smelt tank used to melt raw materials and form melten glass and leading path 200 connected with smelt tank and used to lead melten glass out of the smelt tank; flowing-down device 300, making the melten glass flowing out through leading path 200 flow down; glass shaping device 400, having many shaping dies which are used to shape the melten glass flowing down; transportation device 800, transporting glass shaping products shaped by many shaping dies; and the first shifting device 500, used to shift glass shaping products to transportation device 800.

Description

technical field [0001] The present invention relates to an apparatus for manufacturing a glass molded product and a method for manufacturing a glass molded product. Background technique [0002] Conventionally, glass preforms (glass gobs, glass gobs, and glass molded products) used as raw materials for optical elements and the like have been melted with a melting device and shaped into an appropriate size by melting the molten glass. And get. [0003] Continuous melting and batch melting are known as melting methods used in the production process of glass preforms. Continuous melting is suitable for mass production of glass preforms, etc., because the steps of feeding glass raw materials, melting, clarifying, and stirring can be performed continuously. On the other hand, batch melting is suitable for the production of glass preforms with a small total production volume because the input, melting, clarification, and stirring of glass raw materials are performed intermittent...
