The present invention refers to an Integrated Injection-Stretch-Blow Mold suitable for producing bi-orientated thermoplastics containers, which can be installed in an injection molding machine, occupying the space normally destined for injection molds. It consists of a central chassis (8) having in its interior a central block mechanism (30), with the injection cores (6), blow cores (12) and the mechanisms for stretch and blow (9, 13, 23) and for release of the finish containers (18, 20); a motorized rotating system (31), connected to the central block mechanism (30), by a rotating plate shaft (11), for the transport of the performs between at least an injection mold (1) and a blow mold (14) placed around the central chassis (8).

La présente invention concerne un appareil intégré de moulage par injection-soufflage avec bi-étirage adapté à la production de contenants thermoplastiques bi-orientés. Cet appareil peut être installé dans une machine de moulage par injection à l'emplacement destiné habituellement aux moules d'injection. Il se compose d'un châssis central (8) comportant un mécanisme central de type bloc (30) auquel sont fixés les noyaux d'injection (6), les noyaux de soufflage (12), ainsi que les mécanismes de soufflage avec bi-étirage (9, 13, 23) et d'éjection des contenants finis (18, 20). Un mécanisme rotatif motorisé (31), couplé au mécanisme central de type bloc (30) par l'intermédiaire d'un arbre à plateaux rotatifs (11), sert à transporter les préformes entre au moins un moule d'injection (1) et un moule de soufflage (14) placés autour du châssis central (8).
