Abstract

SINCE THE INSIDE DIAMETER 10 OF BLADES IS SMALLER THAN THE INSIDE DIAMETER 11 OF AN ANNULAR PARTITION PLATE 2, THE PARTITION PLATE 2 IS REDUCED IN WEIGHT, AND BY FITTING A RING PLATE 17 TO THE LEADING END OF THE INNER PARTS 15, IT SERVES AS A GUIDE BEFORE BONDING, AND IT IS EASY TO FIT INTO A HOLE 27, AND THE DEVIATION IN AXIAL CENTER IS SMALL AND IMBALANCE IS SMALL, SO THAT THE PITCHES OF BLADES CAN BE MAINTAINED. A SIMPLE DIE STRUCTURE IS REALIZED BY MOLDING THE INNER PARTS 15 AND RING PLATE 17 AT THE FIXED SIDE OF THE INJECTION DIE, AND THE OUTER PARTS 16 AT THE MOVABLE SIDE. BY INJECTING RESIN FROM THE RING PLATE 17, THE RESIN FLOWS FROM THE END OF THE BLADES INTO THE DIRECTION OF THE PARTITION PLATE 2, AND THE SURFACE OF THE RING PLATE 17 IS PUSHED AND PROJECTED, SO THAT STABLE MOLDING OF HIGH YIELD IS REALIZED.
