Pivoting barrel injection molding machine
 An injection molding apparatus comprising two spaced, parallel lower guide rods mounted to an undercarriage. A ram carriage and a barrel carriage are slidingly mounted on the lower guide rods. A feedscrew ram extends from the ram carriage into a tunnel formed in the barrel carriage to inject plastic out of a nozzle attached to the end of the barrel farthest from the ram carriage, and into a mold. Two spaced, parallel upper guide rods extend from the barrel carriage to slidingly engage the ram carriage. A pair of hydraulic cylinders displace the ram carriage with respect to the barrel carriage. A third hydraulic cylinder displaces the barrel carriage with respect to the undercarriage. The undercarriage, pivotally mounted to a base, is pivoted by a screw jack which displaces the undercarriage about an arcuate path.
