摘要
PROBLEM TO BE SOLVED: To provide a control system for the conservation of energy and the enhancement of production efficiency due to the frequency conversion of an injection molding machine capable of controlling the operations of both of the injection molding machine and a frequency converter at the same time by the controller of an injection machine.;SOLUTION: The operations of both of a pressure valve 3 and a flow rate proportion control valve 4 are controlled so that the controller 11 of the injection machine is matched with the different injection conditions of the injection molding machine 1 and process analysis 2 in the injection molding machine 1. The operations of the injection molding machine 1 and the frequency converter 5 can be controlled by the controller 11 of the injection machine. An electromotor 6 and a hydraulic oil pump 7 are continuously provided to the frequency converter 5. The controller 11 of the injection machine is constituted so that the frequency converter 5 corresponding to different machine kinds and the needs of operation one at a time is set corresponding to the maximum output frequency and an upper limit flow rate.;COPYRIGHT: (C)2006,JPO&NCIPI
