An apparatus for injection molding using a stack mold comprising fust and second mold assemblies interposed between a movable platen and a stationary platen comprises at least one centering device for coupling movement of the movable platen to intermediate mold members of the mold assemblies, the centet ing device comprising first and second helical gear mechanisms and a transmission coupling rotation of helical gear segments of the fu st and second helical gear mechanisms Effective pitch of the helical gear mechanisms and the ratio of rotation coupled by the transmission are chosen to maintain the intei mediate mold members centered in or offset from center in the separation between the movable platen and stationary platen.

L'invention concerne un appareil de moulage par injection qui utilise un moule à étages comprenant un premier et un second ensemble moule interposés entre une platine mobile et une platine fixe, comprenant au moins un dispositif de centrage destiné à coupler le déplacement de la platine mobile avec des éléments de moule intermédiaire des ensembles moule, ce dispositif de centrage comprenant un premier et un second mécanisme de cylindres à dentures hélicoïdales et une transmission couplant la rotation des segments de cylindre à dentures hélicoïdales du premier et du second mécanisme de cylindres à dentures hélicoïdales. Le pas effectif des mécanismes de cylindres à dentures hélicoïdales et le rapport de rotation couplé par la transmission sont choisis de façon à maintenir les éléments de moule intermédiaire centrés ou décalés du centre lors de la séparation entre la platine mobile et la platine fixe.
