Abstract

PURPOSE: To prevent a leakage of a casting material and to devise an improvement of an accuracy of a rotor external peripheral surface by inserting a binding metal of a cylindrical form having a taper at an external peripheral surface and slits at an axial direction into a tapered hole of a metal mold and by eliminating a gap between a metal mold and a rotor external peripheral surface.
CONSTITUTION: A casting device is constituted with a fixed metal piece 4, a movable metal piece 5, a metal mold consisting of a middle mold 6 having a tapered hole 13 and a binding metal 7 locating within a tapered hole 13 and binding an external peripheral surface of a rotor 1. The binding metal 7 has slits 14 of an axial direction and is a cylindrical shape, a taper is made on an external peripheral surface and a flange 15 is provided at a diametral narrower side. When the binding metal 7 is shifted to a direction of expanding a diameter of a hole 13, a gap of a slit 14 is widened to slit meet a rotor 1 inside and at an end point shifted towards to a direction of a diameter of a hole 13 becoming narrower, a gap of the slit becomes narrower to bind an external peripheral surface of the rotor 1. Accordingly a leakage of a casting material is eliminated and an accuracy of a rotor external peripheral surface can be made good.
