description Disclosed is a runner extraction structure for a high-vacuum mold. The structure comprises an upper mold, a lower mold and a cavity (3), wherein the left side and the right side of the cavity are in communication with a first runner (1) and an exhaust groove (2) respectively, each of the first runner and the exhaust groove is provided with an extraction apparatus, and a first air outlet (5) is provided, between the extraction apparatus and the first runner, with a buffer component (7) for reducing the flow speed of molten metal. After the first runner is provided with the first air outlet and the extraction apparatus, the vacuumizing efficiency of the cavity can be increased. However, the sectional area of the first runner is relatively large, and the extraction apparatus located at the first air outlet needs to be quickly closed when the molten metal is introduced; and in order to prevent the molten metal from accidentally entering the extraction apparatus, the buffer component is arranged near the first air
