The invention relates to the field of casting, in particular to a casting method for casting a high-precision workpiece. The casting method for casting the high-precision workpiece is completed in cooperation with casting equipment for casting the high-precision workpiece, the casting equipment for casting the high-precision workpiece comprises a box body, a heat insulation funnel is arranged on one side of the upper end of the box body, the heat insulating funnel is provided with a molten iron purifying component towards the middle and lower part of the box body, a filtering and cleaning part is arranged below the molten iron purifying part, a uniform pushing-out part is arranged below the filtering and cleaning part, a heat insulating pipe is fixedly arranged at the lower end of the heat insulating funnel, a mold outlet is formed below one side of the box body, and an impurity outlet is formed below one side, far away from the heat insulating funnel, of the box body. Bubbles in molten iron are completely removed through cooperation of compression and air suction, a pretreating agent and the molten iron are fully reacted through uniform shaking, impurities on a filter screen are effectively cleaned through overturning of hot air and the filter screen, the molten iron of a mold is pushed to be uniform, and a mold cavity is evenly filled with the molten iron.
Description
technical field [0001] The invention relates to the field of casting, in particular to a high-precision workpiece casting method. Background technique [0002] Casting is a commonly used manufacturing method. It has low manufacturing cost and high process flexibility. It can obtain complex shapes and large castings. The accuracy of casting mainly depends on the accuracy of casting molds, the degree of purification of molten iron, and the operation of the pouring process. [0003] The current casting method does not purify the molten iron to meet the high-precision casting requirements. The bubbles in the molten iron are not completely removed, and the impurities in the molten iron are difficult to remove. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned problems in the prior art, and propose a high-precision casting method for castings, in which air bubbles are removed by extrusion, pretreatment agent is added in conjun...
