| Abstract: | The injection system hydraulic diagram of injection molding machine,using two-way cartridge valves based on on/off valve pilot control,was given.Key parameters of the system fluid resistance,modulation frequency,duty cycle,load were analyzed in AMESim.The simulation results show that the principle of the system is feasible,and the position control of cartridge valves core is realized by on/off valve pilot control. |
