Abstract

PURPOSE:To cast a flanged cast iron pipe easily without cracking of pipe by fitting and fixing a molten metal stopping band which is formed with a recess for forming a flange on one surface that faces the inside part of a mold to the annular step part of a cylindrical metallic flask. CONSTITUTION:A cylindrical metallic flask 3 is heated to 300-400 deg.C and is rotated at a high speed. Dry sand of 20-60 meshes and mixed sand wherein a thermosetting resin is mixed with said dry sand are supplied into the flask to form mixed sand layers. The rotating speed of the flask 3 is decreased to 0.1- 3G, and resin sand or coated sand of which the grain size distributions peak at 200-230 meshes is supplied therein to form a forming layer for the straight pipe part of a desired thickness as a whole. Thereafter, a sand stopping plate 11 is removed, and in turn a molten metal stopping band 15 of which both surfaces facing the inside of the mold are formed to resin sand layers 13 and which is formed with a recess 14 for forming a flange in the layer 13 is fitted and fixed to a step part 6 by means of pins 16.
