The invention discloses an integral optical glass forming mould, belongs to the field of an optical glass melting and forming technology, and mainly solves the problems that the glass metal sticky mold and moulded stripes can be easily caused when an optical glass strip is formed. The integral optical glass forming mould is characterized by mainly comprising a forming part and a cooling part, wherein the forming part is an integral forming groove, one end of the forming groove is opened, and an end working surface at another end of the forming groove is a concave working cambered surface; the bottom surface of the forming groove below the end working surface is a lower convex cooling cambered surface, the cooling part is a cooling cavity closely adhered to the cooling cambered surface, and a cooling hole is formed in the cooling cavity; a temperature control thermocouple is arranged above the forming part. The integral optical glass forming mould provided by the invention has the characteristics of the optical glass strip of stable production, high forming temperature and low forming viscosity, thereby being mainly used for the forming of lanthanide series optical glass.
