The invention provides a feeding process of a gray iron flywheel structure, and belongs to the field of gray iron flywheel casting. The bottom surface of a pouring cup is connected with a vertical pouring gate, two ends of the bottom of the vertical pouring gate are connected with transverse pouring gates, a casting is mounted on the transverse pouring gates, a top cold riser is mounted at the top of the casting, an internal cold riser is mounted on an inner ring of the casting, and a local descending surface is arranged on the inner ring of the casting. The problems that in the prior art, the flywheel inner ring cannot be solidified in sequence and shrinkage porosity remains are solved, the top cold riser supplements liquid to a casting and feeds the flywheel outer ring, so that the conditions of insufficient casting and shrinkage deformation of the top of the flywheel are reduced, the design of the internal cold riser is added, specific feeding can be conducted on the flywheel inner ring, and the flywheel i
