ABSTRACT:
A forming apparatus for the manufacture of casting molds made from sand or another moldable mixture by means of a pressure shock wave from a gaseous medium is proposed. The forming apparatus comprises a structural frame constructed from columns, cross beams, and longitudinal beams, a forming combination within the structural frame, and a pressure vessel for producing the pressure shock wave. The pressure vessel is located above the forming combination and is supported by the cross beams of the structural frame. The forming apparatus also includes a filling vessel containing a supply of sand or other moldable mixture for delivery to the forming combination. The filling vessel is located above the forming combination and is supported by the cross beams of the structural frame is such manner that the topmost edges of these cross beams lie in substantially the same plane as the bottom of the filling vessel. This arrangement results in the center of gravity of the apparatus lying within the range of the forming combination. With such a forming apparatus, the pressure vessel can be exchanged for other pressure vessels of even larger size without incurring major expenses.
