Abstract

L'invention concerne un moule à injection de caoutchouc et plastique comprenant un corps tubulaire (1), une vis mobile (2) placée entre le corps tubulaire (1), une matrice (4) reliée à l'extrémité avant du corps tubulaire (1), une tête (3) conique de vis se trouvant à l'extrémité avant de la vis. Dans la matrice est ménagé un orifice conique axial recevant la tête de vis conique afin de former une passage (15) d'écoulement circulaire. Une tête d'injection (5) est reliée à l'entrée du moule en face de la matrice et le passage d'écoulement circulaire communique séparément avec le corps tubulaire et la tête d'injection. Le procédé de moulage par injection consiste à plastifier le matériau injecté sous l'effet de la rotation de la vis, puis à faire entrer sans cesse le matériau plastifié dans le passage d'écoulement sous l'effet de la poussée de la vis pour pénétrer finalement dans la tête d'injection et atteindre la cavité du moule.
