Abstract

Provided is a glass molding shaping device drawing patterns by air blowing, by which glass materials can be shaped into glass lens, which comprises a lower die unit having a tube wall, an inner hole and a lower die kernel covering the inner hole, and an upper die kernel coupling the inner hole and with capability of shifting between a first and a second position. The tube wall has at least one air inlet connecting with the inner hole. The lower die kernel has a first molding surface with the capability of placing the glass material. The upper die kernel has a second molding surface and a first air guiding surface from outside inwardly, downwardly and slantingly surrounding the second molding surface. The first air guiding surface has an outer diameter smaller than the largest outer diameter of the glass lens bottom circumference. When the upper die kernel shifts to the second position, by which makes the glass material be shaped into the glass lens, and the gas inputted from the air inlet can be guided via the first air guiding surface and be blown to the top surface of the glass lens, thus forcing the glass lens to escape from the second molding surface.
