Title (EN) INJECTION CONTROL METHOD AND INJECTION CONTROLLER IN AN INJECTION MOLDING MACHINE
(FR) PROCEDE DE COMMANDE D'INJECTION ET DISPOSITIF DE COMMANDE D'INJECTION DANS UNE MACHINE DE MOULAGE PAR INJECTION
Abstract:
(EN) A method and apparatus for controlling the operation of an injection molding machine by a servo motor that is controlled by a numerical control device. In order to control the injection speed and the pressure maintenance depending upon the time, pulses are distributed to the servo motor until the point of pressure maintenance completion is reached after the injection speed control and pressure maintenance control at preset times are finished, and then the follow-up is carried out to complete the injection control.
(FR) Procédé et appareil pour commander le fonctionnement d'une machine de moulage par injection à l'aide d'un servomoteur commandé par un dispositif à commande numérique. Afin de commander la vitesse d'injection et la pressurisation en fonction du temps, des impulsions sont envoyées au servomoteur jusqu'à ce que le point d'achèvement de pressurisation soit atteint après réglage sur des durées prédéterminées de la commande de vitesse d'injection et de la commande de pressurisation; puis on égalise les irrégularités pour parfaire la commande d'injection.
