Abstract

Improvements in the installations for the hardening of foundry elements made of sand-resin, such as molds, cores and others, characterized by the fact of having, in combination: a sealed, closed and steel container; within this deposit a certain amount of liquid dimethylethylamine that does not fill it but partially in order to form a free space in the upper part thereof; a carbon gas inlet duct, which opens into said container and near the bottom thereof; a conduit for the exit of a gaseous hardening mixture, formed by carbon dioxide and dimethylethylamine, which leaves from said free space of the container, at least one hermetic and closed container, to which said outlet conduit is attached and which contains at least a casting element to be hardened and is provided with at least one discharge orifice, arranged so that said gaseous mixture can not escape through said orifice if it is not diffusing through the element, and, in the two conduits, valve devices for the control of the spill of the carbonic gas and the gas mixture, respectively.
