The beneficial effects of the utility model are：Using monoblock type core core box structure design, i.e., integrally set using loose piece group
Meter, and the blade locating piece and cylinder of setting are used to realize secondary positioning outside loose piece group；Cast using the utility model device
Impeller blade dimensional accuracy it is high, uniformity is highly stable, and without any burr on blade, therefore greatly improves life
Produce efficiency.
Further, using multiple loose pieces on annular groove, each loose piece is complete vane pattern, and fixed
Position mounting groove can fix corresponding loose piece, so that the loose piece can fix all work of other interconnections
Block, prevents from being subjected to displacement between two neighboring loose piece, realizes the built-up sequence and positioning method of its fixation, each blade positioning
Block is provided with a loose piece with corresponding, and is provided with positioning spline between loose piece and blade locating piece, realizes to each
Loose piece carries out the purpose of accurate secondary positioning.
Further, upper holder and lower fixed frame are further fixed using fix bar, its connection is more stepped up
