结晶型塑料注塑平板冷却模型的研究

Study on Cooling Model of Injection Molded Slab of Crystalline Plastics

从注塑的实际出发 ,针对注塑结晶型塑料平板的冷却本质 ,利用有限厚度区域内注塑平板的冷却模型 ,运用数值分析的常用算法和多项式拟合的方法进行计算机精确分析求解。进行了详细的理论推导 ,求得了固液两相内的温度分布。

s Based on the fact of injection molding and the essence of cooling of plastics slab,the study of cooling model of injected slab in limited thickness area was made.Computer programs were developed and combined with numerical method of Numerical Analysis and Regression Analysis to calculate the temperature profiles of solid liquid phase,concretion coefficient and cooling time.
