Abstract

L’invention concerne un système de commande d’un obturateur agencé en coulissement dans une buse d’injection de matière plastique, comprenant : - un moteur électrique couplé audit obturateur pour l’entraîner en coulissement entre une position d’obturation de la buse et une position d’ouverture maximale de la buse, - un dispositif (2) de commande du moteur, comprenant au moins deux composants intégrés dans une carte électronique de contrôle du moteur, lesdits composants étant choisis parmi :* un composant adapté pour réguler la course de l’obturateur à une première vitesse constante,* un composant adapté pour réguler la course de l’obturateur à une seconde vitesse constante, supérieure à la première vitesse,* un composant adapté pour sélectivement bloquer la course de l’obturateur,- une unité de commande séquentielle comprenant au moins deux voies de commande (30, 31, 32), configurée pour envoyer sélectivement un signal électrique de commande au dispositif (2) par l’une et/ou l’autre desdites voies de commande (30, 31, 32) de telle sorte que :- sous l’effet d’un premier signal envoyé par la première voie de commande (30), l’un des composants est activé, - sous l’effet d’un second signal envoyé par la seconde voie de commande (31), un autre composant est activé Figure pour l’abrégé : Fig 1A
