Abstract

L'invention concerne l'industrie des matières plastiques. Presse comprenant deux porte-moules disposés symétriquement par rapport à un arbre horizontal et entraînés de façon à pivoter autour de l'arbre. L'arbre est supporté par les tiges de deux pistons hydrauliques qui fournissent la pression de fermeture des moules pendant la période d'injection. Les moules peuvent s'ouvrir à la manière de volets et comprennent deux autres pistons qui assurent leur fermeture pendant la période de refroidissement. Application au moulage par injection de matières plastiques à cadence élevée.
