An apparatus for producing a solid-forming or foam forming mixture. Feed pipes carry reaction components from storage containers to a mixhead where they merge into a mixing chamber. A separate feed pipe leads into the outlet of the mixing chamber for the introduction of a filler into the reaction mixture. The outlet of the mixing chamber is arranged partially in a tube which is coaxial with a housing. The tube is movable within the housing and acts as a closure for the filler feed pipe.

Apparatus for the production of a solid-forming or foam-forming mixture

The instant invention relates to a method and an apparatus for the production of a foam-forming reaction mixture or homogeneous material-forming reaction mixture from at least two liquid reactants and for the subsequent introduction thereof into a cavity, and in particular into the cavity of a mold. The reactants are introduced into a mixing zone where they are mixed together. The mixture is subsequently fed through an outlet of controlled cross-section and charged into a cavity. In order to carry out the method, an apparatus is provided which comprises a mixing chamber arranged in a housing and having inlet openings for the reactants and an outlet opening for the reaction mixture, wherein an adjustable baffle plate is arranged opposite the outlet opening axially of the outlet opening.
