摘　　要：根据某压铸机的压射系统,设计了一种新的压射系统方案,以提高压射末端的压力,并加强压射速度的可控性。采用AMESim软件对新压射系统进行了仿真模拟。结果表明,压射速度稳定可靠,能够实现快速调节;在系统压力小范围变化,仍可快速调节压射速度,波动小,稳定性好。According to the injection system of an old die-casting machine, a new scheme of the injection system to increase the pressure at the end of the injection and increase the controllability of injection speed were designed. The design of the injection system was simulated with the AMESim software. The results show that the injection velocity is stable and reliable and can be adjusted quickly. In the system pressure small range changes, but still can adjust the injection speed quickly, the fluctuation is small, the stability is good.
