Abstract
Chill mold for casting piston blanks, e.g. for internal combustion engines, from metals such as aluminum alloys, includes a steel cylinder, an inner core for reproducing the inner contours of a piston, and a spray ring which surrounds the cylinder. The spray ring delivers cooling water to the exterior of the cylinder which flows down forming a water curtain around the cylinder.
