Abstract
An injection molding machine has a machine frame, a stationary mold mounting plate and a mold mounting plate which is movable by a closure mechanism which is formed for example by a crank drive or a bell crank mechanism. The movable mold mounting plate and the stationary mold mounting plate are connected without beam members and exclusively by way of the machine frame so that the closing force which occurs during the closing procedure and the driving-open force which occurs during the injection between the mold mounting plates are passed only by way of the machine frame. A mold height adjustment mechanism is included and the closing force is transmitted from the closure mechanism by way of the mold height adjustment mechanism to the movable mold mounting plate.
