ABSTRACT:
A mold closing device without cross-beam for a molding machine, e.g. injection molding or blow molding is disclosed. The mold closing device has a U-shaped machine frame with two arms defining a horizontal injection plane and a movable positioning device located within the first arm and moving along the injection plane; a moveable adapter plate including a vertical mold mounting surface, located on the positioning device; a fixed adapter plate with a vertical mold mounting surface on the second arm and on the injection plane; a first mold die-half is attached to the essentially vertical moveable adapter plate; a second mold die-half is attached to the essentially fixed adapter plate; and one of the arms includes a weakened cross-section for providing a controlled deformation of the machine frame resulting from the occurring closing and holding forces during operation of the molding machine and for maintaining the mold mounting surfaces vertical.
