A swiveling type plastic working machine such as a forging machine having a slanted molding die holder which is swivelled about a vertical axis. The molding die holder is fixed with a first molding die confronting a second molding die on which a workpiece is mounted. Rotation of the molding die holder about its axis is also controlled in connection with a slanting angle thereof relative to the vertical axis so as to provide no slippage between the first die and the workpiece, or so as to provide a controlled slippage therebetween.
