Abstract

PURPOSE: To prevent the curving and distortion caused by flowing of excess glass and enable the surface formation of a glass cell by only pressing, by inserting a pair of board-shaped molds at both inner side-faces becoming rough surfaces in a glass box, heating to soften the glass, separating the molds from each other, inserting a center piece between the board- shaped molds and pressing an outer mold from outside. CONSTITUTION: A pair of board-shaped molds 31 are lowered into a glass box 41, and all members are lowered into a heating furnace 50. They are heated to bring the glass box 41 to at or above the glass softening point. After the glass box 41 is softened, the board-shaped molds 31a, 31b are separated from each other to expand a pair of side-faces to become optically functional faces. Subsequently, a center piece 11 heated up to around the glass transition point in advance is lowered and placed in the glass box 41 in such a manner as to insert it between the molds 31a and 31b. Then, the furnace 50 is retreated, and the center piece 11 the board-shaped molds 31a, 31b and the glass box 41 are integrally placed in an outer mold 61. Subsequently, the outer mold 61 is fastened to press the side-faces of the glass box which are held between the outer mold 61 and the center piece 11 and to form optically functional faces. After cooled, the center piece 11 and the board-shaped molds 31a, 31b are pulled out and the glass box 41 is separated from the outer mold 61 to obtain the objective glass cell.

As described above, according to the glass cell manufacturing method and manufacturing apparatus of the present invention, since the side surface forming the optical function surface is thinly stretched by preliminarily performing tensile molding with a plate mold, the surplus is excessive. There is only a small amount of glass, and excess glass does not overflow and the glass container is bent and deformed. Therefore, a rectangular glass cell can be manufactured only by press molding without the need for polishing work.
