The utility model relates to the technical field of mechanical die, and provides a pressing die for graphite packing ring, including a core shaft, a pressing ring, a sleeve ring and a base. The base includes a body and a convex platform installed at one end of the main body. The lower end of the sleeve ring is sleeved on the convex platform and butted with the end face of the main body. A groove is arranged on the convex platform, the lower end of the core shaft is accommodated in the groove, and the pressing ring is installed between the core shaft and the sleeve ring. An air vent is arranged on the base, and the air vent runs through the main body and the convex platform. The pressing die of the graphite packing ring provided by the utility model locates the sleeve ring and the mandrel on the base through the convex platform and groove set, limits the radial freedom of the sleeve ring and the mandrel in the pressing process, thus avoiding the radial dimension deformation of the pressed product and improving the product quality. The ventilation hole set on the base is beneficial to maintaining the balance of the internal and external pressure in the pressing process, and provides good results. Good suppression environment.
