The utility model relates to an aluminum alloy wheel mould feeding structure, casting die cavity between last mould and lower mould are used for shaping hub blank, and the valve port slash department system of hub blank has the counter weight to cast the nest, and the last mould lower part outer wall system of casting litter positional correspondence with the counter weight of hub blank has a feeding recess, and the radial dimension that the nest is cast to radial dimension and the counter weight of the feeding recess is the same, casts litter corresponding inside rims position formation feeding piece in the counter weight. The utility model discloses main last mode structure through optimizing the casting die realizes, it increases the feeding passageway that"recess"structure increaseed the foundry goods to correspond the position at last mould, specifically increases the feeding piece for cast the corresponding inside rims position of nest in the counter weight, increases the feeding passageway at here position, though this institutional advancement simply, can be effectual carries out the feeding to the rim, has improved the casting quality of rim.
