Abstract

Tête de mélange auto-nettoyante pour mousses de matière plastique, du type à mélange par turbulence. La tête de mélange 17 comprend une chambre délimitée par deux demi-coquilles 18, 19 séparables. Les deux demi-coqui les 18, 19 sont fixées sur les demi-moules 22, 23 de sorte que la tête de mélange 17 s'ouvre avec le moule 24, ce qui permet de démouler la carotte 27 en même temps que l'objet moulé 28. Application notamment au moulage de mousses de polyuréthane.
