| Abstract: | Traditional injection molding machine has inherent flaws of excessive power consumption and overflow loss. Aiming at these problems, this paper proposes a control strategy for injection molding machine's pressure and flow output, through torque and speed control of the asynchronous servo motor. In the hydraulic power source system, a series double gear pump structure is firstly designed to meet the large output requirement of instantaneous flow for large injection molding machines. The closed loop control is then presented to enhance output precision of pressure and flow, and improve energy saving effect of the injection molding machine hydraulic system. By conducting on field experiment, it is verified that the proposed electronically controlled double pump hydraulic system has superior performance compared with traditional injection molding machine hydraulic system, and introducing asynchronous servo motor pump control can greatly reduce energy consumption. |
