Abstract
A multiple-piece cam unit for use in a molding machine. The cam unit has a cam track which engages cam followers of mold assemblies of the molding machine to move the cam followers between a first position and a second position. The cam unit includes a first cam section and a second cam section. The first cam section has an entrance portion which is dimensioned to receive the cam followers therein. The second cam section has an exit portion positioned to release the cam followers therefrom. The second cam section is moveably mounted to the molding machine to allow the exit portion of the second cam section to be moved relative to the entrance portion of the first cam section, 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.
