A modular injection molding machine has an extruder/injector assembly, a carriage assembly for carrying the extruder/injector assembly, a first clamping apparatus for holding an associated first mold, a main frame assembly which supports the first clamping apparatus and, a first adder module assembly. The first adder module assembly is selectively operatively connectable to the main frame assembly and is used to support a second clamping apparatus at any selectable laterally spaced distance. The carriage assembly selectively carries the extruder/injector assembly between the first and second clamping apparatuses. The preferred clamping apparatus has a first clamp assembly which is rigidly connected to an associated support member, a second clamp assembly which is movably connected to the first clamp assembly, a lower platen assembly which is operatively connected to the first clamp assembly, an upper platen assembly which is operatively connected to the second clamp assembly and, a moving device for selectively moving the second clamp assembly. The first and second clamp assemblies form a collapsible C frame support structure. To add an adder module to a modular injection molding machine, first a base plate is positioned at any selectable laterally spaced distance from a bottom plate. Next, a front plate is placed on a front shelf on the base plate. A back key is then installed, being received within a back key slot on the bottom plate and within a back key slot on the base plate. After that, a tie bar is connected to the bottom plate, the first plate, the base plate and the front plate. A front key is then installed, being received within the key slot of the first plate and within a key slot of the front plate. Finally, a second clamping apparatus is connected to the front plate.
