Abstract
Described is an apparatus for the production of transversely ribbed tubes, having mold jaw halves which bear against each other along a common mold section and form a mold passage. Each mold jaw half has a cooling passage which is produced directly during the operation of casting the respective mold jaw half, for example by means of a so-called false casting core. The cooling passage extends in the corresponding mold jaw half from a first surface to a second surface so that said core can be easily removed from the casting of the mold jaw half. At the one surface, the cooling passage has a cooling agent feed means and, at a spacing therefrom, a cooling agent discharge means. The second surface which is at a distance therefrom is sealed off by means of a guide and slide element which is fixed to the corresponding mold jaw half.
