Problems solved by technology

[0002] The centrifugal main engine of the centrifugal pipe casting machine is used in the processing of ductile iron pipes. During the processing of ductile iron pipes, molten iron needs to be poured into the pipe mold. The centrifugal main engine drives the pipe mold to rotate at a high speed, so that the molten iron is formed in the pipe mold and cooled. Casting into pipe fittings, before pouring molten iron into the pipe mold, it is necessary to block the socket end of the pipe mold with a sand core to prevent the molten iron used in pouring from flowing out, and then pour molten iron into the pipe mold from the socket end of the pipe mold. In the technology, the sand core is manually placed on the socket end of the pipe mold, and automatic core loading cannot be realized. The efficiency of manual operation is low, the work intensity is high, and the safety factor is low.
[0003] In view of this, a centrifuge dedicated to casting ductile iron pipes is disclosed in the patent document with the announcement number 201621484921.0. The centrifuge in the above reference document is suitable for the processing of ductile iron pipes with a pipe diameter of 400mm or less, but cannot be used for 400mm ~800mm or 800mm~1200mm pipe fittings processing, and at the same time, the centrifuge in the above reference file replaces the pipe mold and adjusts the height of the pipe mold manually by relying on experience. This adjustment method has large errors and large labor costs. If the screw lifter is adjusted, the cooling water in the centrifugal host will enter the screw lifter, which will reduce its service life
