INJECTION DEVICE |
摘要 |
In an injection apparatus 100, an acceleration cylinder 2 and booster cylinder 3 for driving an injection cylinder 1 connected to an injection plunger are connected in parallel with each other with respect to the injection cylinder 1. A piston 2P of the acceleration cylinder 2 and a piston 3P of the booster cylinder 3 are synchronously driven by a motor 10, a ball screw 11 and a nut 12. A pilot operated check valve 4 and flow rate adjustment circuit 5 are provided between a bottom chamber 1B of the injection cylinder 1 and a bottom chamber 2B of the acceleration cylinder 2. Moreover, flow rate adjustment circuit 7 is provided between a rod chamber 1R of the injection cylinder 1 and rod chambers 2R and 3R of the acceleration cylinder 2 and booster cylinder 3. The injection apparatus 100 uses the driving force of the motor 10 to drive the injection cylinder 1 at high speed by means of both the acceleration cylinder 2 and the booster cylinder 3 and to drive the injection cylinder 1 at high pressure by means of only the booster cylinder 3. |
