Abstract
Moule d’injection-compression (1) comprenant une matrice et un poinçon (2) définissant entre eux une cavité de moulage dans une configuration de fermeture du moule d’injection-compression (1), et comprenant une couronne d’étanchéité (4) montée mobile en coulissement autour du poinçon (2), ledit moule d’injection-compression (1) étant caractérisé en ce que la couronne d’étanchéité (4) comprend plusieurs tronçons de ceinture (5) munis d’extrémités jointes deux à deux par des connecteurs (6) pour former une ceinture autour du poinçon (2), chaque connecteur (6) formant une liaison de compensation entre les deux extrémités concernées et étant conformé pour autoriser un mouvement relatif entre les deux extrémités tout en maintenant les deux extrémités concernées en contact entre elles.
