Title:
【発明の名称】射出圧力制御における圧力波形設定方法及び射出成形機
Document Type and Number:
Japanese Patent JP2650070
Kind Code:
B2
Abstract:
A waveform of injection pressure as being a target value of feedback control of injection pressure is set in conformity with a real waveform of injection pressure detected when a good molded item is obtained. Or, setting is made possible by correcting a waveform of injection pressure which has been already stored or a real waveform of injection pressure. A waveform of injection pressure which has been already stored or a real waveform of injection pressure is displayed on a screen of a display device (T1). By specifying two points on the waveform of injection pressure thus displayed, the waveform of pressure is corrected in conformity with a line connecting these two points (T3, T6, T8). Alternatively, by specifying two points on the waveform of injection pressure and a point therebetween, the waveform is corrected in conformity with a circular arcuate line connecting these three points (T4, T7, T8). The waveform of injection pressure thus corrected is set as a target value of feedback control of injection pressure (T8, T9).
