Abstract
The chill mold is mounted on a support which is rotatable about the vertical axis of its casting cavity and is composed of a lower element, an upper element which has a pouring opening, and four peripheral elements arranged in two opposing pairs. The lower element occupies a casting position on the support and coaxial therewith, the upper element is movable between a casting position in which it overlies the lower element coaxially, and a shakeout position in which it does not interfere with the upward removal of the piece from the mold, and the peripheral elements are displaceable radially on the support to allow their movement from a casting position, in which together they surround the upper and lower element, to a shakeout position in which they are further removed from the axis of rotation. The elements of the chill mold are provided with locking keys which are mutually engageable due to the movement of a first pair of the opposed peripheral elements towards their respective casting positions when the lower and upper elements and the opposed peripheral elements of the other pair are substantially in their respective casting position. Keys are also provided for locking the peri…
