The invention discloses a reusable graphite gating and feeding hole. The reusable graphite gating and feeding hole is characterized by comprising a gating and feeding hole, wherein the gating and feeding hole is provided with a cooling device; a spring heating ring and a temperature measuring head are arranged on the outer wall of the gating and feeding hole; a vacuum insulating sleeve is arranged on the spring heating ring, and a metal positioning ring is arranged at the lower end of the spring heating ring; the outer wall of the positioning ring is provided with two small lugs for positioning and a large lug; and the large lug is internally provided with an installing seam, a positioning hole and a positioning screw hole. The gating and feeding hole made of graphite with high purity, high strength and high density does not need coating in use, is fast in temperature control response and is durable; due to the adoption of the cooling device arranged above the gating and feeding hole, aluminum liquid in the gating and feeding hole can meet feeding and condensation, and then aluminum material can be solidified, so that the pouring and separation are convenient; the outer wall of the gating and feeding hole is heated by adopting the spring heating ring, so that the volume is small and the temperature control is fast; the outer wall of the spring heating ring is insulated by adopting the vacuum insulating sleeve, so that both the effects of saving the volume and energy can be achieved; and the metal positioning ring connected under the gating and feeding hole is adopted, so that the service life of the graphite gating and feeding hole is effectively prolonged and the cost is low.
