Adjustable multiple-piece cam track

A rotary molding machine comprising;

• a pair of turntables rotatably mounted on a shaft;
• a plurality of mold clamp assemblies mounted on and spaced around the turntable, the mold clamp assemblies having cam followers which are mechanically connected to mold halves of the mold clamp assemblies, the cam followers being moveable between a first position, in which the mold halves of the mold assemblies are maintained in a closed position, and a second position, in which the mold halves of the mold assemblies are maintained in an open position;
• a multiple-piece cam unit mounted to the molding machine, the cam unit having a cam track which engages the cam followers, the cam unit comprising:
• a first cam section, the first cam section having an entrance portion, the entrance portion dimensioned to receive the cam followers therein;
• a second cam section, the second cam section having an exit portion, the exit portion positioned to release the cam followers therefrom, the second cam section being pivotally mounted relative to the molding machine, the second cam section being independently adjustable relative to the first cam section to allow the exit portion of the second cam section to be moved relative to the entrance portion of the first cam section;
• whereby the exit portion of the second cam section can be adjusted to insure that the cam followers exiting the exit portion of the second cam section are properly aligned to enter the entrance portion of the first cam section as the turntables are rotated.
