Abstract
L'invention concerne une tête de mélange et d'éjection de composants liquides interagissants, pour moulage de matières plastiques. Selon l'invention la tête comporte une chambre de mélange des composants, en communication avec un conduit de sortie; les orifices d'un premier et d'au moins un deuxième conduit d'alimentation des composants débouchent dans la chambre de mélange précitée, cette dernière étant placée latéralement par rapport au conduit de sortie et son axe formant un angle avec l'axe du conduit de sortie lui-même. L'invention est particulièrement appropriée pour le moulage par injection ou par coulée dans un moule d'articles en matière plastique.
