Abstract:
T he chang e of pressure and temper ature plays an impo rtant ro le in inject ion molding . With bet ter understanding the principle of f illing process and the viscous-elastic mechanics theo ry, the pressur e equatio n and the temperature equat io n for the melted polymer w ere put fo rw ar d in this paper. And a new numerical method cal led the f inite analy tic metho d fo r so lving par tial differ ent ial equat ions is employ ed in flow simulat ion of inject ion molding . Filling a thr ee-dimensional plast ic bo x is simulated in this paper . T he chang e of pr essure and temperature is analy sed in the simulatio n resul t . According to the predict ion of the chang e of pr essure and temperature, the mold desig ner can predict w hether the f illing process is r at ional.
