Abstract

L'invention décrit une tête de mélange sous pression d'au moins deux constituants réactifs, générateurs d'une matière plastique. En position haute, un plongeur permet l'entrée des constituants dans une chambre de mélange et il passe en position basse pour expulser ce mélange. A l'extrémité d'une tige, qui coulisse dans le plongeur, un organe de retenue fait saillie dans la chambre de mélange pendant l'arrivée des constituants; le mouvement du plongeur pour expulser le mélange entraîne l'organe de retenue dont l'extrémité libre vient se loger dans un évidement du plongeur. Application : possibilité de régler sans démontage une tête mélangeuse pour le moulage par injection d'une matière plastique.
