Abstract
A mixing valve is located at the opening of a mold cavity to control the flow of a fast setting mixture into the mold and to mix the ingredients forming the mixture immediately prior to dispensing into the mold. The valve includes a plurality of mixing elements on a mixing head which rotates about its own axis within the valve housing and which cooperates with the housing to define a mixing chamber receiving the ingredients. When the valve is open, the plurality of mixing elements supported from the head in the mixing chamber are rotated with the head to mix the ingredients into the fast setting mixture. The head also reciprocates along its axis to open and close the valve and completely fills the chamber to eject the mixed ingredients when the valve is closed.
