Device for the production of corrugated pipes

A device for the production of corrugated pipes from thermoplastic, in which mold jaws, which complement each other in pairs, move together in a cycle along a mold section that leads away from an extruder head;

• the mold jaws being capable of being moved apart at the end of the mold section and returned to its beginning separately from one another with a mold section device for the movement of the mold jaws along the mold section, which has a supporting table with drive means for the mold jaws on the mold section, and a return conveying device for the return conveyance of the mold jaws from the end of the mold section to its beginning, which has an outlet assembly to move the mold jaws apart at the end of the mold section and/or an inlet assembly to move in the mold jaws at the beginning of the mold section, characterized in that the outlet assembly and/or the inlet assembly has drive means, which can be moved perpendicularly with reference to the plane of the supporting table, characterized in that the drive means of the inlet and/or outlet assembly are supported by a holder or a frame, which can be adjusted via a scissors-type lever mechanism or a parallelogram lever mechanism, perpendicularly, with reference to the plane of the supporting table.
