摘要
本设计通过了解注射机的工作原理及其机构组成，分析其典型零件的组成及动作原理，并通过液压系统的工况分析，初步计算确定其主要技术参数，设计其液压系统，选择合理的液压原件，使油泵电机的转速与注塑机工作所需液压的流量与压力乘积成正比，将传统的定量泵改造成变频变量泵，从而使溢流阀的回油流量降到最小，无高压节流能量损失，进而将传统有高压节流的“耗能型”注塑机升级为无高压节流的“节能型”注塑机.

ABSTRACT
This design constitutes through work principle and its organization that understanding injects machine, analyze constitute of its typical model spare parts and act principle, and pass the work condition that the liquid presses system analysis, the initial calculation make sure it main technique parameter, design its liquid to press system, choose a reasonable liquid to press an original piece, make the oil pump turn of electrical engineering soon with note Su machine discharge and pressure product that the liquid press that work need into a direct proportion, reform a traditional metered pump change the Pin change to measure a pump, make to overflow to flow the return of valve oil discharge to decline to least thus, have no high pressure to reduce expenses energy loss and then have tradition to"consume ability type" that the high pressure reduce expenses to note Su machine to get stripe for have no the high pressure reduce expenses of"economy energy type" note Su machine.
