Abstract
PURPOSE:To improve the rigidity of an impeller by forming a helical groove on a shaft-shaped mold and giving a turning motion to a material in its flow while arranging fibers in this helical groove part to be oriented along the peripheral direction for the axial center, when the impeller is manufactured by injection molding with the fiber reinforced plastic material. CONSTITUTION:An impeller 14 in an exhaust turbine or the like of a turbocharger comprises a boss part 14c, back plate part 14b and a blade 14d, forming a through hole 14a for a rotary shaft to penetrate in a center shaft part. This impeller 14 is integrally formed by so-called injection molding, in which a fiber reinforced plastic material A is allowed to flow into a metal mold B, and the through hole 14a is formed by using a center pin 13 serving as the shaft-shaped mold. Here, forming a helical groove 13a on the peripheral surface of the center pin 13, when the material A is allowed to flow in, the impeller 14 generates a flow of the material A in the periphery of the center pin 13 so as to be turned along the helical groove 13a, thus arranging a fiber C in a part of the through hole 14a so as to be oriented along the peripheral direction for the axial center.
