An injection moulding machine has a framework (1), a fixed and a movable die platen (2, 8) and at least a piston-cylinder unit of a cylinder platen (3) that bears a hydraulic or electromechanical closure mechanism. The cylinder platen (3) and the fixed die platen (2) are interconnected only by the framework (1). The closure force exerted during injection moulding and the vertical thrust between the cylinder platen (3) and the die platen (2) are transmitted only through the framework (1). The intersection between the longitudinal center axis (LSK) of the closing die (5) and the longitudinal center axis (LBF) of the die platen (8) lies at the back of the movable die platen (8) and the point at which the force of the closing die (5) is transmitted to the movable die platen (8) is vertically displaceable in relation to the die platen (8).
Injection moulding machine with a machine frame, one stationary and one movable die platen and, a hydraulic or electro-mechanical closing mechanism carried on an end plate of the machine frame, said closing mechanism being provided with a closing piston moveable with respect to the end plate, the closing mechanism for displacing the movable die platen on guide rails provided on the machine frame, wherein the end plate upon which the moveable die is supported and the stationary die platen are connected exclusively by the machine frame, and the die platens locked together are inclined, under the influence of the closing mechanism, slightly out of a plane perpendicular to the machine frame, and a hinge is provided near to the closing piston which joins together a hinge part assigned to the machine frame and a hinge part assigned to the moveable die platen, characterized in that, when hinged, apart from a tilting movement, the hinge part belonging to the movable die platen performs a radial displacement relative to the machine frame, the radial displacement directed preferably approximately normally to the longitudinal axis of the machine.
