EXTRUSION PRESS FOR DIRECT AND INDIRECT EXTRUDING WITH DIE SHIFTER Abstract of the Disclosure A gate lock housing mounted against the rear face of the front platen of an extrusion press has a passage through it aligned with a passage through the platen. A tubular block is normally disposed in the housing passage where it is held by releasable gate lock means. Behind this block is a laterally movable carrier, in which is seated a bolster member having a passage through it aligned with the block passage. An indirect extrusion stem secured to the bolster extends rearwardly from the housing and supports an extrusion die at its rear end. The bolster is connected to the block in such a way that the bolster can be moved forward with the block but can move laterally away from the block when they are in their rear position. Shifting means detachably connected with the carrier can slide the bolster and stem laterally away from the block and out beyond one side of the housing, where the carrier can be supported while being disconnected form the shifting means. A second carrier and stem or a carrier supporting a direct- extrusion die then may be connected to the shifting means for return to extruding position.
