In an indirect extrusion press provided with a gate lock and a rearwardly extending indirect-extrusion stem, the stem normally extends through a die slide with the rear end of the stem engaged by a loose die disposed in the front end of a billet container behind the stem. After a ram has extruded a billet through the die and the gate lock has been released, the stem is moved forward clear of the die slide as the die is pushed into the slide, which is then moved transversely of the extrusion stem and out to the side of the gate lock housing for cleaning or replacement of the die.
