A shot tip assembly for an injection molding machine of the type having a shot tube for conducting molten material into a die cavity of the machine. The shot tip assembly has a shot tip which is reciprocal within the tube and forms a close sliding fit with the tube for forcing the molten material through the tube and into the die cavity. A shot tip adapter is provided for the shot tip and has one end captively but relatively movably mounted in the shot tip, the adapter being connected at the other end to a reciprocal shot rod. A movable or swivel connection is provided between the adapter and the tip to permit the tip to move or swivel slightly on the adapter to thereby accommodate any misalignment between the shot tube and the shot tip as they are moved relative to one another. The injection machine with which the shot tip assembly is used has power means for example, a hydraulic shot cylinder for driving the shot rod, and consequently, the shot tip in the shot tube.
