To fix the injection mold on the machine platens mounting clutches can be used. One of the two ends of the clutch stays on the mold. The other one rests on the platen of the machine. A screw applies the force to hold each side of the mold securely. It is screwed into one of the holes of the platens. It should be noted, that ejection side and injection side of the mold need to be clamped.
