摘　　要：对某型注塑机液压系统进行改进设计,将该型注塑机顶模机构的液压中子并联起来。对改进后的注塑机液压系统进行AMESim仿真实验和改进实验,均验证了改进后的注塑机可以缩短注塑成型周期,并可实现二级调速。此改进方法不增加其他液压阀,方法简单且成本低廉,可以提高企业的生产效益。An optimal design for an injection molding machine hydraulic system was made. The hydraulic neutrons of top mold of the injection molding machine were paralleled. Simulation experiments based on AMESim software and practical improved experiment were made, The experimental results verify using the improved injection molding machine, injection molding cycle can be shortened, and two step speed regulation can be realized. Adopting this improved method, other hydraulic valves are not needed. The method is simple and has low cost, enterprises production efficiency can be improved.
