  • Molding tool for the production of plastics moldings by the reaction injection molding process
    Publication number: 20070087078
    Abstract: A molding tool for the production of plastics moldings by the reaction injection molding process is described. These plastics moldings are preferably prepared from a reaction mixture comprising a polyurethane molding composition. The molding tool comprises at least two molding tool halves, i.e. an upper mold half and a lower mold half, which together form a mold cavity when in the closed position, a supply pipe for transporting the reaction mixture via an external mixing head connector which connects the supply pipe to an external mixing head, a storage chamber which receives the reaction mixture from the supply pipe, and a plunger which is movably arranged in the storage chamber, characterised in that the end face of the plunger forms part of the inside wall of the mold cavity formed by the two mold halves when the plunger is in the extended state.
