【Abstract】 The hydraulic system including high-speed injection parts of injection molding machine has been developed. The simulation model for high-speed injection system was obtained by using AMESim software. The influence of key parameters is analyzed in electro-hydraulic servo system in terms of dynamic control effect of screw during injection process. Both the control strategy and implementation method of electro-hydraulic position-speed servo system are introduced.The control of double variables for the injection position and speed is realized in the same system and the optimal simulation results have been obtained.更多还原
