| description | An injection device has an injection cylinder for driving a plunger, a gas pressure type accumulator which supplies hydraulic fluid to the injection cylinder, a hydraulic fluid supply device which supplies the hydraulic fluid to the accumulator, a pressure sensor for detecting the gas pressure of the accumulator, and a control device which controls the hydraulic fluid supply device so as to suspend the supply of the hydraulic fluid when detection value of the pressure sensor reaches a predetermined target gas pressure before injection in the state where the hydraulic fluid is supplied from the hydraulic fluid supply device to the accumulator in a molding cycle. |
