32, the tube sleeve 4, the annular plate 5, the second air valve tube 51, the baffle 6 and the baffle ring 7 move synchronously along with the second electric slide block 403, and then the annular plate 5 enters the cavity formed between the tube blank 11 and the tube core 12, during the moving process of the annular plate 5, as a small amount of pits and salient points may exist on the surfaces of the tube blank 11 and the tube core 12 after pouring and molding, and dust and other impurities are easy to adhere to the surfaces and the pits of the tube blank 11 and the tube core 12 during the storing process, so as the annular plate 5 moves, the polishing layer on the annular plate 5 rubs the salient points on the surfaces of the tube blank 11 and the tube core 12, the bumps are ground flat, under the condition that the small pump does not work, the elastic sheets 72 enable the tilting parts 71 to bend into the shape shown in fig. 11 through the elasticity of the elastic sheets, meanwhile, the small pump outside the pipe sleeve 4 is controlled to work, the pump is used for conveying air into the annular plate 5, the second through holes 53 are blocked by the baffle 6, air in the annular plate 5 enters into the baffle ring 7, the tilting parts 71 on the baffle ring 7 are pushed up by the air along with the air entering, the lifted tilting parts 71 are separated from the annular plate 5, the tilting parts 71 on the baffle ring 7 on the outer ring surface of the annular plate 5 are not contacted with the inner ring surface of the pipe blank 11, the tilting parts 71 on the baffle ring 7 on the inner ring surface of the annular plate 5 are not contacted with the outer ring surface of the pipe core 12, the elastic sheets 72 are stretched, the air pressure in the

blown out through the second air valve tube 51, the blown-out air will blow out the dust in the inclined pits, the blown-out dust will be blocked by the blocking ring 7, thereby avoiding the dust flowing to the middle of the cavity formed between the tube blank 11 and the tube core 12, at the same time, since the polishing layer on the annular plate 5 is almost in one contact with the tube blank 11 and the tube core 12, the air pressure in the area between the polishing layer and the blocking ring 7 will increase with the blowing of the second air valve tube 51, since the raising portion 71 is disengaged from the annular plate 5, the air will enter into the through groove 73, and then be discharged outwards through the first through hole 52, during which the dust blown up by the second air valve tube 51 will also be discharged outwards with the air, at the same time, when the air is conveyed into the annular plate 5 by the peripheral small pump, the small pump will suck the air in the cylinder tube 3 so that the first valve tube 31 will generate an adsorption force, so that the dust will be sucked into the cylinder tube 3 by the first valve tube 31 when the dust is discharged outwards through the first through hole 52, and the dust in the cylinder tube 3 will be sucked by the adsorption plate 32 so as to avoid the dust from re-entering the annular plate 5 through the small pump, so that in the cooperation of the cylinder tube 3, the first valve tube 31, the adsorption plate 32, the tube sleeve 4, the annular plate 5, the second valve tube 51, the first

blank 11 and the tube core 12 in the following, the connection degree between molten steel and the tube blank 11 and the tube core 12 is enhanced, when the two annular plates 5 are to be moved to the middle position of the tube blank 11 and the tube core 12, the left annular plate 5 is controlled to stop moving, the right annular plate 5 is continuously moved to be in contact with the left annular plate 5, and then the right annular plate 5 and the left annular plate 5 are simultaneously controlled to be moved to the middle position of the tube blank 11 and the tube core 12, so that the annular plate 5 can be subjected to all treatment on the surfaces of the whole tube blank 11 and the tube core 12.
When the right annular plate 5 moves to be in contact with the left annular plate 5, the left and right second electric sliding rails 402 are controlled to enable the second electric sliding blocks 403 to move back to reset, in the process, the small pump in the pipe sleeve 4 is controlled to pump air in the annular plate 5, as the air pressure in the annular plate 5 is reduced, the second air valve pipe 51 is closed, the baffle ring 7 is reset, the baffle plate 6 is opened, air in a cavity formed between the pipe blank 11 and the pipe core 12 enters the annular plate 5 through the second through holes 53 and is pumped out by the small pump, the air is not completely pumped out in the moving process, the excessive difficulty in resetting caused by excessive external atmospheric pressure is avoided, and when the annular plate 5 moves to the end faces of the pipe blank 11 and the pipe core 12, the air in the cavity is completely pumped out, so that compared with the prior art, the air pumping opening is directly arranged at the end faces of the pipe, the air pumping time can be shortened, and two functions of air pumping and surface finishing are realized through one mechanism.
Meanwhile, when the small pump works, the small pump can convey air in the cylindrical pipe 3, then the air is blown out through the first air valve pipe 31, the blown air can further blow out dust in pits on the pipe blank 11 and the pipe core 12, then the air in the cavity is pumped out along with the annular plate 5, the phenomenon that bubbles are easy to generate when molten steel is injected due to the fact that a large amount of air exists in the cavity in the process of injecting molten steel into the cavity in the follow-up process, and a large amount of cavities exist after solidification of the molten steel is caused can be avoided, and therefore the strength of a product is affected.
