ABSTRACT:
A mechanism for the clamping attachment of interchangeable injection molding dies to the die carrier plates of an injection molding machine featuring a plurality of clamping plungers in axial guide bores of the die carrier plates, each clamping plunger having a clamping nose engaging a clamping shoulder of an oversized back plate of the die half, clamping the latter against the die carrier plate, when it is forcibly retracted by means of a transversely guided wedge rod traversing the clamping plunger and driven by a hydraulic cylinder assembly in a self-locking taper drive configuration. The injection molding dies are insertable and removable in either a horizontal or a vertical direction.
