Abstract
A die clamp assembly for an extruder comprises at least one passage through which product being extruded flows. The die clamp assembly is attached to an extruder and comprises a last barrel that is connectable to the extruder. The last barrel comprising a flange and the extruder and last barrel define at least one passage through which product flows; at least one die body comprising at least one die body passage that communicates with the at least one passage; and at least one die plate that comprises at least one die plate passage that communicates with the die body passage and at least one opening so product can be extruded from the at least one opening. A clamp collar assembly connects corresponding peripheral surfaces of the last barrel to the die body, and comprises a closed position that connects the last barrel to the die body and an open position that permits separation of the last barrel and the die body. Further, a pivot assembly pivotally supports the clamp collar assembly for movement in a first direction and a second direction and the die body for movement in the second direction. The die body and the die plate are pivotable away from the last barrel when the clamp collar assembly has been pivoted to the open position.
