Isostatic pressing die for net forming ball

The utility model provides an isostatic pressing die for net forming of balls, and belongs to the field of refractory metal forming. The isostatic pressing die for net forming of balls includes a die body having an interior space with a near-ball portion and an extension portion, and a pluggable seal assembly mated with the extension portion. During use, metal powder is filled into the internal space of the mold main body, the sealing assembly is mounted after the metal powder is knocked down, then the mold main body is put into an isostatic press to be pressed, the sealing assembly is dismounted after pressing, and demolding is performed. The isostatic pressing die for the near-net forming ball is simple and compact in structure, convenient to use and high in use efficiency, the next operation can be carried out without shaping after isostatic pressing forming, the problem that shaping of spherical products wastes time and labor is solved, the production cost of tungsten or molybdenum powder metallurgy spher
