Abstract:
Apparatus for the production of transversely ribbed tubes, which comprises: mold jaw halves which bear against each other along a common mold section with front faces thereof and which form a mold passage, with each mold jaw half having a cooling passage; wherein the cooling passage of the respective mold jaw half is produced in a casting process and has at a first surface a cooling agent feed means, and at a spacing therefrom a cooling agent discharge means and, produced directly in the casting procedure, the cooling passage extends to a second surface of the corresponding mold jaw half which is different from the first surface; a guide and slide element fixed to the respective second surfaces by which the cooling passages are sealed off at the second surfaces; and wherein the first and second surfaces of the respective mold jaw halves are disposed in a mutually opposite relationship and are arranged in a mutually parallel relationship and are oriented substantially perpendicularly with respect to the front face of the respective mold jaw half.
