Injection molding machine having tiltable mounting plates

An injection molding machine comprising a machine frame, a stationary and a movable mold mounting plate, a cylinder plate carrying a closing mechanism for exerting a closing force during a closing phase and for resisting an expansion force during an injection phase of the molding machine, wherein the cylinder plate against which the movable mold mounting plate is supported and the stationary mold mounting plate are connected without bars exclusively by way of the machine frame so that the closing force which occurs during the closing phase and the expansion force which occurs during the injection phase as between the cylinder plate and the mold mounting plate are passed only by way of the machine frame, means for mounting at least one of said mold mounting plates tiltably about a horizontal axis, and a guide between the movable mold mounting plate and the machine frame, the guide including a guide rail mounted to the machine frame and at least one slide shoe carried on the movable mold mounting plate and slidable on the guide rail, and further including in the guide at least one spring permitting resilient tilting movement of the movable mold mounting plate.
