Abstract
A method is described for uphill casting in sand molds with high-resin casting cores or especially casting cores containing binders, and with directed solidification of metallic castings that have at least one cavity. In particular, these are prototypes of engine blocks or cylinder heads, for example for internal combustion engines that are provided with a cavity through which coolant water flows. To provide for low-turbulence flow of the liquid molten metal during the deaeration of the casting mold, the casting mold is provided with at least one feeder head that is connected through a casting system to an infeed funnel, and the molten metal it contains is displaced by gravity through the casting system into the casting mold, with the cavity in the molten metal being subjected after the filling to reduced pressure that is greater than the pressure of the core gases formed in the core. This eliminates the hindrance to filling the mold from air pockets in the mold. At the same time, dense and pore-free, mechanically strong cast parts are produced by the method.
