Abstract

An injection molding machine comprising a substantially C-shaped machine frame, on the one limb (9) of which is mounted a stationary mold mounting plate (2) and on the other limb of which is mounted a closing mechanism for driving a movable mold mounting plate, wherein the free ends of the limbs of the machine frame, which ends are not connected by beam members, deform under the influence of the closing force which occurs during the closing operation, and wherein at least one of the mold mounting plates (2) and/or an end plate carrying the closing mechanism are respectively supported against the closing force at their upper and lower edges, and the lower support of the mold mounting plate(s) (2) or the end plate (3) respectively is formed by a bending pin (10) which extends transversely with respect to the longitudinal direction of the machine.
