摘要： A method of manufacturing a glass substrate for a storage medium by pressing a glass material between an upper and a lower dies. The method includes a heating step of heating the glass material arranged between the upper and lower dies, a pressing step of pressing the heated glass material via the upper and lower dies, and a cooling step of having, after the pressing step, a cooling member contact the upper and lower dies to cool them together with the molded glass material arranged between the upper and lower dies. During the heating step and the pressing step, a vacuum atmosphere is maintained in a space containing the dies and the glass material. When the pressing step has completed, an inert gas is filled in the space to set a pressure in the space equal to an ambient pressure.

摘要： The object of this invention is to provide a press die for press forming of glass, which is capable of preventing the generation of interdiffusion between a matrix material of press die and a releasing film, making it possible to retain the excellent releasability of the releasing film for a long period of time. Matrix body is covered by a diffusion preventive film, which in turn is covered with a releasing film. In this example, the matrix body is constituted by a sintered body of tungsten carbide (WC) containing 3 wt% of titanium carbide and none of metal-based binder, the diffusion preventive film is constituted by a sputtered film of niobium (Nb) 0.05 micrometer in thickness, and the releasing film is constituted by a sputtered film of an alloy consisting of platinum (Pt) and iridium (Ir) 0.3 micrometer in thickness. The diffusion preventive film may be a high-melting point metal such as Ta, Hf, Zr, Re, Ir, Mo, Rh, Ru or Os other than Nb.

摘要： A molding apparatus for glass molded product includes a mold, a press shaft and a release device. The release device includes a release member, a push bar, and a release action mechanism. The release member has a lower end surface to face an outer peripheral portion of a molding surface of the lower die of the mold. The push bar adjusts a downward pressure given to the release member. The release action mechanism is provided to hold an upper portion of the push bar movably along a shaft direction of the press shaft. The release action mechanism moves the push bar and the release member downward along the shaft direction to release a glass material and the upper die of the mold when the upper die and the lower die are separated after the glass material has been pressed between the upper die and the lower die.
