HORIZONTAL COMPOSITE DIE FOR CENTRIFUGAL PRESSURE CASTING AND CENTRIFUGAL PRESSURE CASTING METHOD USING THE DIE

摘要

PURPOSE: To provide a horizontal composite die for centrifugal pressure casting capable of efficiently manufacturing various castings of different shape and to provide its centrifugal pressure casting method. ;CONSTITUTION: An inner die 1b to which a plurality of sand molds of donut shape are connected are internally fitted to and held by a metallic cylindrical outer die 1a which is rotatably arranged in a horizontal centrifugal casting machine. A cavity C1 formed between the outer and inner diameters of the inner die 1b forms a fin part or a rib part formed on the outer circumference of a tubular body, and the total length part of a center cavity equivalent to the inner diameter of the inner die is used as the cavity C of the tubular body, and the center line of the inlet/outlet of the fluid on the right and left ends of the cavity agrees with the center line of the center cavity of the sand mold. The coating agent is applied on the inner circumferential surface of the inner die and on the cavity for casting to be formed between the outer and inner diameters of the inner die, and the inner die is fitted to be held, and then, casting is achieved by pouring the molten metal in the inner die while it is rotated.;COPYRIGHT: (C)1997,JPO
