CASTING MOLD, ESPECIALLY DIECASTING MOLD, METHOD FOR PRODUCING THE SAME AND METHOD FOR LOW PRESSURE DIECASTING

摘要

The invention relates to a casting mold, especially a diecasting mold, which comprises a base layer (2), a permeable filter layer (1) having a filter layer permeability (k1) across a surface of the base layer between the base layer and a casting chamber (6), a first conduit device (50 - 52) for supplying slip (S) to the casting chamber, and a second conduit device (5) for discharging liquid (W) from the casting chamber through the filter layer and/or for supplying a pressure medium (L) for removing the body formed in the casting chamber. The base layer is made up of firmly interlinked bulk material having a base layer permeability (k2). The filter layer penetrates the base layer to a certain degree starting from the surface and is linked in this area with the base layer. The second conduit device can optionally be provided with a connection for applying a negative pressure (p1). In another embodiment, the base layer and/or the filter layer of the diecasting mold is subdivided into at least two sections (8, 8*) by means of a dividing wall (9), said sections (8, 8*) being separated from each other in terms of pressure or conduits.
