微结构塑件模具温度控制探讨

Study on temperature control of mould for plastic microstructure part

由于微型件结构上的特点,微结构注射充满型腔的能力要比常规注射差得多。通过对塑料熔体在型腔中的流动性分析和模具温度控制方式的比较,确定了微结构塑件在注射过程中模具温度控制的优化方案。这种方法对于指导实际生产具有较高的实用价值,并取得了良好的效果。

Because of the structural feature, it is much more difficult for plastics to fill the mould cavity of mini parts than that of normal parts. Through the analysis on liquidity of plastic melt in cavity and comparison between control modes for mould temperature, the optimal method of control of mould temperature in the injection process for mini parts was determined. Effective result has been achieved and high use value will it be found in practical application.
