Abstract
PURPOSE: To produce valves free from casting defect, by placing a sand mold having an inverted conical opening coinciding with umbrella part opening, on a die having a cavity consisting of shaft part and umbrella part being placed with the umbrealla part side upwards, and using a compound mold thus formed.
CONSTITUTION: A die 1f for casting having a cavity 11 to make shaft part and umbrella part of a value is placed with the umbrella part side opening upwards, and a sand mold (shell mold) 2f of excellent ventilation property having a molten metal pouring port 26 provided with an inverted conical opening 261 coinciding with said umbrella part opening is placed thereon to form a compound mold. When casting by using said mold, a blow hole indicated by shaded zone is formed in the head part of the cast product, but since a valve is made by cutting off the part above the shaded zone, no defect is caused on the valve product. The angle of inclination θ of said inverted conical form should be preferably 25W45 degrees.
