英语翻译
In the injection molding process of regular parts the heat
flow from the polymer melt to the mold wall during the
filling stage can be neglected due to the short filling times.
However,the local heat flow has a high impact on the
polymer flow in the surface structures during the filling
stage and is considered by a one dimensional heat conduction
model.The freezing of the polymer melt in surface
structures depends significantly on the temperature level
chosen on the mold wall and the glass-transition temperature
of the amorphous molding material used.
Therefore,in order to mold surface structures with
higher qualities a higher mold wall temperature is necessary
which results in increased cooling time.In contrast,
parts with a lower surface quality allows for a reduction in
mold wall temperature.Due to the higher temperature
gradients occurring in the filling and cooling stages the
cooling time is then reduced significantly.

在常规零件注塑成型的过程中,由于充模期短暂,在充模阶段熔化到铸模壁上的聚合体形成的热流可以忽略不计.然而,在充模阶段,表面构造中局部的热流对聚合体具有极高的影响并成为一元热传导模型的考虑因素.熔化到表面构造的聚合体的凝固大大取决于铸模壁上选取的温度位和所用的非晶体成型材料的玻璃化转变温度.因此,为了以更高质量塑造表面结构,更高级别的铸模壁是必要的,这种铸模壁会造成冷却时间增加的结果.相比之下,具有低级别表面质量的部件则对铸模壁温度降低要求宽松.由于充模和冷却阶段出现的较高温度的变化率,冷却时间则会大大减少.
