摘　　要：加热系统中热板温度场的均匀性是衡量橡胶注射机使用性能的主要技术指标。一直以来,由于单凭经验排布,导致热板加热不均匀和温度控制精度低,直接影响橡胶注射机使用性能,是目前生产注射机企业急需解决的难题。现通过正交试验法安排试验,并基于Patran/Marc进行模拟仿真来获取试验数据,研究试验范围内各变量对温差的影响,从而获得最佳热管功率分布和热点偶位置。试验所得最佳方案经实际生产验证,切实可行。The temperature uniformity of hot plate in specifications in measuring the operational performance mould heating system is one of the main of rubber injection machines. The layout of electrothermal pipes by experience is likely to lead to uneven heating and low temperature control precision, which directly affects the operational performance of rubber injection machines. A new method based on orthogonal experiment and Patron/Marc was designed to make analog simulation to acquire data. The effect of variables on temperature difference was studied; and an optimal power distribution of heat pipes and locations of thermocouples were obtained.
