Abstract

The present invention relates to a glass molding apparatus with simplified disassembly/assembly procedure, which is capable of fabricating glass material with a coefficient of thermal expansion to a glass lens. The glass molding apparatus comprises a first circumference; a first aperture; an outer sleeve with a first coefficient of thermal expansion larger than the coefficient of thermal expansion aforementioned; a inner sleeve with a second coefficient of thermal expansion, which has a second circumference and a second aperture, installed in the first aperture; a lower die, which has a third coefficient of thermal expansion, installed in the second aperture; and a upper die with a fourth coefficient of thermal expansion, which has a top side, installed in the second aperture. The second, third, and fourth coefficients of thermal expansion are less than the first coefficient of thermal expansion, and the first circumference has a first top side so that when the upper die moves downward to the top side aforementioned and becomes aligned with the first top side, a glass lens can be formed therefrom.
