Meanwhile, the second motor 403 is started, the rotation of the second motor 403 drives the first gear 402 to rotate, and then drives the gear ring 302 to rotate, the rotation of the gear ring 302 drives the gear rack 602 to move through the fixing plate 601, and then drives the second gear 603 to rotate, the rotation of the second gear 603 drives the rotating rod 506 and the rotating fan 507 to rotate, so that external air enters through the through hole 704 and enters the air blowing pipe 501 after being filtered by the filtering sponge in the mounting pipe 702, meanwhile, the rotation of the rotating rod 506 drives the driving bevel gear 801 and the driven bevel gear 802 to rotate, and then drives the threaded rod 902 to rotate, the threaded rod 902 enables the threaded sleeve 903 to move upwards, and then drives the sealing disc 504 to move upwards to the annular groove 502 through the connecting plate 703, the mounting pipe 702 and the moving rod 701, at this moment, the air enters the inside of the die body through the air blowing hole 503, negative pressure is avoided to be generated inside the die body, the convenience is further avoided when the upper die 1101 is demolded, the waste of energy is avoided, and the external unfiltered air can be prevented from entering the inside of the die 1101 through the combining part of the upper die 1101 and the lower die 1101, and the manufacturing quality of the turbine 1101 is ensured;
And, the air passes through the gas vent 503 and gets into inside the mould body for at the in-process of loosing core, can blow the operation to the turbine, on the one hand can clear up its surface, on the other hand can improve its refrigerated efficiency, when guaranteeing turbine manufacturing quality, improves its manufacturing efficiency.
