METHOD FOR PRODUCING A CAST COMPONENT WITH A CAST-IN PIPE.

摘要

The invention relates to a method for producing a cast component (1) of an internal combustion engine with a cast-in pipe (3) in a casting process with expendable moulds and a permanent pattern or a casting process with permanent moulds, in which a solid core mould (4) is mounted in a split outer mould. To solve the problem of the pipe changing its position during the casting of the component (1), it is proposed according to the invention that a separate pipe holder (5) is integrated in the outer mould or the core mould (4). The pipe (3) is inserted into a holding portion (6) of the pipe holder (5) that is formed in such a way that it locally surrounds the outer circumference (8) of the pipe (3) at least partially and with little play, so that the pipe (3) can expand in the axial direction during casting, but is secured against displacements in radial directions caused by the buoyancy forces of the liquid casting material. The component (1) is subsequently cast by the respective process.
