Casting of a cylinder crankcase and a process for the preparation of with the use of a casting mold with filigree one-piece insert core

摘要

The present invention relates to a casting having at least one row of in a cylinder head boundary surface in each case a cylinder and cylinder recess ′ ″, which opens out between the web between two 40,41 of the row, wherein the at least one cylinder between the web of a web with a cooling channel along the row of the measured 40,41 minimum width of less than 3,5 mm. The present invention also relates to a casting mold for the production of such a casting and a process for the production of the casting. It is the object of the present invention, a casting which can be produced simply and reliably with cast thin cylinder between the struts and the narrow web cooling channels, as well as a corresponding casting mold and to propose a suitable production method. The object of the invention is achieved by means of a casting of the type defined above, characterized in that the web a cooling channel with the use of an at least in one area of the volume of the casting to be cast integrally formed insert core cast component is, of the casting, wherein the web cooling channel with two in the further exclusively by means of the cylinder head boundary surface extending and with the use of the insert core produced is connected to the connection conduits, and wherein the web cooling channel and the connection conduits for an exclusive connection to the cylinder head cooling circuit are dimensioned.
