[0003] Since a cast pipe obtained by using the above-mentioned mold does not have a bolt hole in a flange, drilling must be performed after casting. The execution of this machining impairs productivity and causes an increase in manufacturing cost. Drilling is very difficult when the pipe is a hard pipe for wear resistance. As a remedy, it has been proposed to form bolt holes as cast holes (Japanese Patent Laid-Open No. 4-55047).
No.). As shown in FIG. 7, the mold has a round bar-shaped core (43) for forming a cast-out hole attached to a stepped vertical wall surface (11) of a mold body, and a flange-forming core (4).
The structure has a structure in which a flange forming space (S) is defined by mounting a core ring (45) accompanied by 4).

The above-mentioned casting mold has a structurally required accuracy of the set position and the fixed state of the core for forming a punched hole.
A flanged tube cast by centrifugal force is not sufficiently stable, so that burrs are likely to occur in the cast hole portion, and the shape and dimensional accuracy of the cast hole are poor in stability. When casting burrs occur, machining is required to remove them, and when the shape and size of the cast holes are out of the allowable error range, machining is required to correct them. The present invention provides an improved casting mold for overcoming the above-mentioned problems in the centrifugal force of a flanged tube.
