Abstract:
A casting arrangement for filling a mold with a casting mass comprising:a mold formed with a closed top by joining two mold half sections and having a mold cavity enclosed by molding sand, the closed top of said mold being free from additional elements; a downwardly extending straight uptake formed by grooves in the mold half sections, a first top end of said uptake extending into the mold cavity; a casting container containing the casting mass and including a vertically aligned feed tube, said casting container receiving the mold half sections such that said straight uptake is vertically aligned with said feed tube, and the opposing end of said uptake is in communication with the mold cavity, the casting mass being force fed through said feed tube and said uptake into the mold cavity; an outwardly open channel formed into the molding sand in the mold cavity and extending into a vicinity of the top end of said uptake, said channel being oriented transversely with respect to the axis of said uptake; a connection on said casting container for enabling application of feed pressure (p) into said casting container; and means for applying a horizontal force through said outwardly open channel to close said uptake at a closing position adjacent to and closer to a lower end of the mold cavity than to an upper end of said feed tube, wherein the closing of said uptake defines an upper uptake portion above the closing position having casting mass within and a lower uptake portion below the closing position, the casting mass in the lower uptake portion being capable of returning to the casting container through said vertically aligned feed tube.
