Abstract
PURPOSE: To insure the die-casting of vanes and raise the accuracy thereof by making an outer shell and inner core which are divided in upper and lower portions at the center of blades and casted into unitary radial bodies so tha the monolithic coupling thereof may be made by the division faces thereof.
CONSTITUTION: An outer shell 1 and an inner core 4 are molded by casting into unitary radial bodies the upper and lower pieces 3 and 5 obtained by dividing blades at the center thereof. A vane 7 is formed by coupling the pieces 3 and 5 by the division faces 3a and 5a thereof. Dies 10 and 11 are used for casting the blades 3 and 5 and after molding pulled off in the directions of arrows (a) and arrow (b) respectively. Die-casting can thus be made without using any core. The blades protrude from the surface of the outer shell 1 and inner core 4. Therefore, the coupling faces thereof can be easily machined so that vanes can be obtained with a high accuracy.
