本系统参考国内外对注塑机液压系统的最新研究成果，采用流量不同的两个泵并联供油的开式系统，来满足各阶段对速度的不同要求，快速时双泵合流，慢速时大泵卸载，小泵供油。
Referring to domestic and foreign newest research result on the injection machine hydraulic circuit, this system takes an open type including two parallel connected pumps with different rates to satisfy the various requirements for the speed at each stage. To be specific, double pumps concourse during fast speed whereas large pump unloads and small one supplies oil.

为了保证足够的合模力，采用液压——机械增力合模机构，增大合模油缸的推力。系统所需的多级压力，由并联的远程调压阀控制。
In order to ensure sufficient mold clamping force, the system uses hydraulic pressure--mechanical reinforcement matched molds mechanism to increase the thrust of its hydrocylinder. The multi-level pressure required by the system is under the control of the parallel connected remote pressure regulator valves.

本系统除了采用时间继电器控制保压和冷却动作外，其余都采用行程开关控制各油缸依次动作和进行速度换接。由于注塑机空间的复杂性，很难通过二维图表达清楚注塑机液压系统的管道铺设。
Except the use of time relay to control the pressure m
