Abstract
A mixing head for a mold can receive two or more reactive synthetic resin components in a mixing chamber in which a mixing-chamber piston is displaceable to drive the residues into a first calming chamber communicating with the outlet of the mixing chamber. The first calming chamber also has a piston or plunger which can be advanced to drive the residues into a second calming chamber connected to the outlet of the first calming chamber. The second calming chamber has a second piston displacing the mixture into the mold cavity. Because the pistons of the first and second calming chambers can be retracted as the mixture flows through these chambers, a highly effective calming effect can be obtained for the turbulent mixture of the mixing chamber without throttling.
