| 摘 要： | 由于模内复膜工艺是在模具内将塑件表面增加一层薄膜，本文利用注塑冷却分析将模具型腔表面离散为平面三角单元的特点，将薄膜和塑件视为两层具有良好接触的平板，对于每一层平板，建立第一类边界条件下一维非稳态导热模型，并将该导热模型应用到冷却分析中，完成了模内复膜冷却分析的建模. |

| Abstract: | In-mold labeling processing adds a label on the part surface in mold.It is a new technology and is becoming more and more popular.It affords the mold designer far greater latitude in the design of graphics, part shape and the use of multiple molded components in a single molded unit. But the CAE technology in injection molding can’t meet the need of the new processing.There is no suitable mathematical model established for the processing.The cavity surface is always meshed in planar triangular elements. Supposing that the label and part are two plates in perfect contact,unsteady heat transfer model was established under first dissymmetry boundary for each plate.This heat transfer model was used in cooling analysis for mathematical modeling of in-mold labeling for cooling analysis in injection molding. |
