摘　　要：鼠笼电机转子质量直接影响电机的性能。立式压铸工艺是工业电机常用的生产工艺。传统立式压铸采用增压方法达到一定的压射比压,压射系统常在超高压状态下工作,易产生故障影响生产,同时增压的滞后对产品质量的提高不大,转子填充率较低。大比压压铸工艺通过增大压射缸与压铸熔杯的面积比,利用中等蓄能器压力实现一次性大比压压铸,设备工作稳定,不易发生故障,转子的内在质量明显改善,填充率比传统工艺提高了3%~5%,对整机性能有较大提升。The squirrel-cage rotor plays a critical role in motor performance.Vertical die-casting is a common production process for industrial motors.The traditional vertical die-casting technique adopts a boosting method to achieve a certain injection ratio pressure,and the injection system is often operated in an ultra-high-pressure state.It is likely to cause failures in production.What’s more,the lagging of pressurization has limited help in quality improvement,and the rotor filling rate is low.The high pressure ratio die-casting process increases the area ratio of the injection cylinder to the die-cast melting cup,using the medium energy accumulator to achieve one-time high pressure ratio die-casting.The equipment works stably and is not prone to failure.Compared with the traditional technique,the quality of the produced rotor is significantly improved,and the filling rate is increased by 3%~5%,which greatly improves the overall performance of the motor.
