Abstract
A production method for producing cast parts from metal using a sand casting mold (). The sand casting mold () is produced in this case in a molding box () by means of a negative-pressure molding method. According to the invention, the sand casting mold (), which is under negative pressure, in the molding box () is first of all filled with molten metal (). The molding box () with the sand casting mold (), which is under negative pressure therein, is then completely or partially impinged upon by a cooling fluid () and after, at the same time as, or before the cooling fluid impingement is opened at places with cooling fluid impingement. As a result of this, cooling fluid () is sucked into the sand casting mold () which is under negative pressure, as a result of which the solidifying cast part () is quenched more quickly.
