For this reason, the mold material must be chemically inert to glass even at high temperatures, the glass pressing surface of the mold must be sufficiently hard and resistant to damage such as scratches, and it must also be suitable for pressing at high temperatures. It is necessary that the mold does not undergo plastic deformation, has excellent heat resistance and thermal shock resistance, and that the mold has good workability and is capable of precision machining.Mold materials that relatively satisfy these properties are required. For example, silicon carbide (SIC) or silicon nitride (Si3N4) is used as shown in Japanese Patent Application Laid-Open No. 52-45613,
Furthermore, there are also mixed materials of titanium carbide (Tic) and metals, which are disclosed in Japanese Patent Laid-Open No. 59-121126, and various studies have been made.

形することができなかった。Problems to be Solved by the Invention As described above, in the case of conventional mold materials such as silicon carbide and silicon nitride, their hardness is extremely high, so it is difficult to process the glass press surface into a spherical or aspherical shape with high precision. was extremely difficult. Moreover, since these materials are all sintered types, they contain a third component as a sintering aid to improve their sintering properties, so they are relatively weak compared to glass elements containing lead or alkali elements. It easily reacts, and when press molding is repeated, the reaction between the mold and the glass element progresses, causing the glass to adhere to the mold, making it impossible to mold a highly precise optical glass element with good image formation quality.

On these base materials, an alloy film containing 95 to 100 wt% of Ir, which has poor reactivity with optical glass elements and high hardness, and the balance is Pt, or an alloy film containing 95 to 1 wt% of Ru, is formed.

An alloy consisting of t, an alloy containing 95 to 98 wt% O3 and the balance being Pt, and an alloy consisting of 95 to 98 wt% Rh and the balance being Pt react with optical glass containing lead or alkali elements at high temperatures. We found that the specified alloy composition is sufficiently hard and does not cause scratches on the mold surface, nor does the alloy film undergo plastic deformation when pressed. By forming it on a certain material such as tungsten carbide, cermet, or zirconia base material and using it as a press molding mold for optical glass elements, it has become possible to directly press mold optical glass elements with good image formation quality and high precision. It is something.
