Abstract
PURPOSE: To reduce the variations in the dimensional accuracy of split dies and obtain the cast products of high accuracy by manufacturing the plural split dies of the same shape to be die-registered at the captioned casing by the precision casting method using single main pattern.
CONSTITUTION: A rotation symmetrical part, for example, heat-resistant impeller 1 has 9 vanes and consists of 9 minimum same shape parts. Thereupon, the dies 2 capable of forming the cavity conforming to this are constituted by the split dies 2aW2i of the same shape. To manufacture these dies, the lost pattern of approximately the same shape as that of these dies is made from a single main pattern of wax or the like and an ingate and sprue of the same material are bonded thereto. After a refractory material layer is formed on its outside circumference, wax is melted away to obtain the mold. Molten metal is poured therein and after it has frozen, the mold is knocked out, whereby the dies 2aW2i is manufactured. These are disposed movably forward and backward in the radiation direction and casting is done in the cavity formed in their advance position, whereby the product 1 is obtained.
