As shown in fig. 1-2, the utility model relates to a structure is got rid of to multistage pump runner, dig subassembly 1 including carbon, the base 2 of rectangle form, the top surface of base 2 is equipped with a plurality of supporting seat 3, supporting seat 3 is used for the level to place multistage pump's the pump body 4, the inside runner packing of the pump body 4 has grit 5. The carbon plane is adopted to remove the sprue 6 on the multistage pump body 4, so that the removal is convenient and the effect is good; meanwhile, sand is filled in the flow channel in the multi-stage pump body 4 in advance, so that splashes generated by the carbon plane are effectively prevented from entering the flow channel, and a good protection effect on the pump body is achieved.
In this embodiment, the number of the supporting seats 3 is four, and the four supporting seats 3 are distributed in a rectangular shape, that is, the four supporting seats are respectively arranged at four vertex angles close to the base.
In this embodiment, the supporting seat 3 is in an inverted T shape, and the lower end of the supporting seat 3 is fixed to the base 2 by screws.
In this embodiment, the carbon gouging assembly 1 includes an air gouging gun 101, and a carbon rod 103 is clamped on a chuck 102 of the air gouging gun 101. It should be noted that the gouging gun is a mature product in the prior art, and the structure formed by the gouging gun and the carbon rod is similar to that of the carbon arc gouging gun in the prior art, and the working principle of the gouging gun is not repeated here. The pouring gate on the pump body of the multistage pump is removed by adopting the carbon planing technology, so that the removing effect is good, the efficiency is high, impurities, splashes and the like generated in the removing process can be blown away as much as possible by airflow generated by the carbon planing, and the possibility of remaining in the pump body is reduced.
In this embodiment, the pump body 4 of the multistage pump is of a horizontal open-center structure, the multistage flow channels 401 are distributed in the pump body 4 of the multistage pump along the axial direction of the multistage pump, and sand 5 is filled in each stage of flow channel 401.
