The hydraulic system design of injection machine
 Abstract
 This paper studied the design of small injection molding machine hydraulic system. In this paper, taking 250g injection molding machine hydraulic system design for example.The design was beginning with clearing tasks and requirements, analyzed the hydraulic system to be completed with basic movements and sequence ,and then studied several basic control circuit hydraulic system analysis and comparison module, choose the most appropriate solution. After identifying the right oil circuit control program, the design of injection molding machine according to hydraulic structure design, which includes a hydraulic actuator load force and load torque calculation, calculation of main parameters of hydraulic system, hydraulic motor displacement calculation, hydraulic actuators and choice of hydraulic components, hydraulic actuators and the required practical work flow calculation of the pressure to develop system solutions and development of hydraulic system diagram, checking the performance of hydraulic systems, etc.. Summed up the entire design process analysis to determine the system schematic, hydraulic structure design, selection of hydraulic components and hydraulic system performance checking.
