Abstract
In an injection molding machine having a machine frame, a stationary mold mounting plate, a movable mold mounting plate and a support portion on the machine frame, which carries a mold closing mechanism, the support portion and the stationary mold mounting plate are connected exclusively by way of the machine frame. The closing force which occurs during the closing phase and the expansion force which occurs during injection, as between the support portion and the stationary mold mounting plate, are carried only by way of the machine frame. The mold mounting plates are mounted tiltably about a respective horizontal axis while a guide means is provided between the two mold mounting plates or the movable mold mounting plate and the machine frame.
