ABSTRACT:
An injection molding machine is proposed, especially for injection stamping of large-area plastic moldings, that has at least a first injection mold which has two mold halves and which forms a first cavity with a first projected area, and a second injection which has two mold halves and which forms a second cavity with a second projected area, one mold half of each of the two injection molds being fixed on a common carrier unit. A support means for the two injection molds acts in the opening direction. In order to limit the force acting on the respective cavity, the support means, depending on the respective projected area of the respective cavity, partially take up the clamping force so that a holding pressure force acting on the material which has been injected into the respective cavity is set.
