A method produces a cast component of an internal combustion engine with a cast-in pipe. Expendable molds and a permanent pattern, or permanent molds are used in the method. A solid core mold is mounted in a split outer mold. To solve the problem of the pipe changing its position during the casting of the component, a separate pipe holder is integrated into the outer mold or the core mold. The pipe is inserted into a retaining section of the pipe holder that is configured in such a manner that it locally surrounds the outer circumference of the pipe at least in part and with little play so that the pipe can expand in the axial direction during casting but is secured against displacements in radial directions caused by buoyancy forces of the liquid casting material. Subsequently the component is cast.

Method for producing a cast component with a cast-in pipe

The invention relates to a cast part for an internal combustion engine, said part being a cylinder crankcase, which has at least one guide duct that leads a fluid medium to a required location. Said guide duct is provided in the form of a tube and is embedded inside the part when the latter is cast. The aim of the invention is to reduce the complexity of production and the costs of the cylinder crankcase. To this end, the fluid medium is provided in the form of oil and the at least one guide duct is provided in the form of an oil supply leading to a crankshaft bearing and/or to a camshaft bearing that are to be lubricated or to other required location.

A mold for casting cylinder blocks of combustion engines in an upright position includes a cope and a barrel core located therewith for defining a cylinder bore. A drag defines a crank space and is configured for cooperating with the cope to define a cylinder block such that the drag and cope can be stripped in an axial direction with respect to the cylinder bore.
