An injection moulding machine comprising a machine
frame (1), a stationary and a movable mould mounting
plate (2, 8) and a cylinder plate (3) carrying at least
one piston-cylinder unit (7) of a hydraulic or
electromechanical closing mechanism. The cylinder plate
(3) at which the movable mould mounting plate (8) is
supported and the stationary mould mounting plate (4)
are connected without struts exclusively by way of the
machine frame (1). The closing force which occurs
during the injection operation and the expansion force
between the cylinder plate (3) and the mould mounting
plate (2) are only passed by way of the machine frame
(1). One of the mould mounting plates (2, 8),
preferably the movable mould mounting plate (8), is
mounted tiltably about a horizontal axis.
