According to the casting mold and the casting method of the aluminum-iron composite brake disc, a sprue spreader and a plurality of radial grooves evenly distributed around the sprue spreader are formed in the bottom face of a forming lower convex part of an upper mold of the mold, and a side mold assembly comprises a plurality of side mold single blocks evenly distributed along a circular ring; an annular containing cavity is formed by the annular inner concave portion of the bottom of the side die assembly and the downwards-concave annular groove of the lower die, the cast iron working ring body and the air duct die core are placed in the annular containing cavity, and the air duct die core is placed between the upper cast iron working ring body and the lower cast iron working ring body. The upper die, the side die assembly, the lower die, the cast iron working ring body and the air duct die core jointly define a cavity of the aluminum-iron composite brake disc. The pouring system comprises a pouring gate,
