[Prior Art] Molding methods are widely used in the manufacture of optical glass articles such as aspherical glass lenses, ball lenses, prisms and the like. It mainly uses Direct Press-molding to produce optical glass products, which require no subsequent processing steps such as grinding and polishing, which can greatly improve production efficiency and yield, and the product quality is good. The mold for general molding comprises an upper mold core and a lower mold core, and the mold core comprises a substrate and a protective layer on the molding surface of the mold core. The substrate may be selected from a metal or a metal alloy having heat resistance and sufficient strength, such as tantalum carbide, tungsten carbide, or the like. The protective layer is generally a ruthenium carbide having high heat resistance, oxidation resistance, impact resistance and good release property. In order to improve the bond between the protective layer and the substrate, some of the matrix and the protective layer of the mold have an intermediate layer, usually Ni metal, which improves the durability of the mold.
