Abstract

Procédé pour compenser les hauteurs de moule différentes de moules de moulage par injection pour les commandes de machines de moulage par injection. On amène en contact, sans interposition de moule, les deux plateaux porte-moule dont le plateau mobile est en liaison de fonctionnement avec un codeur absolu, un dispositif indicateur relié à la suite du codeur absolu est alors réglé à zéro, après mise en place d'un moule, celui-ci est amene en position de fermeture et la valeur indiquée par le dispositif indicateur est amenée au moyen d'un commutateur à décades à l'entrée de soustraction d'un comparateur à la deuxième entrée duquel est appliquée la valeur de sortie du codeur absolu, de telle sorte que le dispositif indicateur relié au comparateur indique la valeur zéro, ledit comparateur étant relié à la pièce de commande de la commande de la machine de moulage par injection dont les instructions de commande dépendent de la hauteur du moule.
