Injection moulding machine

Injection molding machine for injection stamping of large-area plastic moldings, comprising:

• 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 mold which has two mold halves and which forms a second cavity with a second projected area, the second projected area being different from the first projected area such that one of said projected areas is larger than the other projected area
• a common carrier unit on which one mold half of each of the first and second injection molds is disposed,
• means for applying a clamping force, sufficient to produce a desired holding pressure in the cavity with the larger projected area, to both of said first and said second injection molds and
• support means for acting on at least one of the two injection molds in an opening direction when said first and second cavities are closed,
• wherein the support means, depending on the respective projected area of the respective cavity, partially take up the clamping force acting thereon and separately set a holding pressure force acting on material which has been injected into the respective cavity such that said clamping force sufficient to produce the desired holding pressure in the cavity with the larger projected area is adjusted to a desired different holding pressure in the cavity which has a smaller projected area.
