| 摘 要： | 以模内装饰技术(IMD)测试平板为研究对象，利用仿真和实验方法分析薄膜滞热的影响因素及薄膜滞热对成型工艺的影响规律。结果表明，薄膜滞热使动模侧模具温度场变化滞后于定模侧温度场，且在实验条件下达到8.6 ℃的最大温度差；薄膜滞热随着模具温度的增加而降低，随熔体温度和薄膜厚度增加而升高；薄膜影响熔体的充模与冷却，造成产品冷却不均的现象；薄膜滞热导致产品翘曲变形增加。

| Abstract: | In this paper,taking the in-mold decoration test plate as a research object,the influence factors of film heat-lag effect and the influence on the molding process were analyzed by simulation and experimental methods.The results indicated that the film heat-lag effect generated the hysteresis of temperature change for the moving mold side compared to the fixed mold side,and there was a maximum temperature difference of 8.6°C under the experimental conditions.The film heat lag decreased with an increase of mold temperature,but increased with the increase of melt temperature and film thickness.The filling and cooling of the melt were influenced by the film,resulting in uneven cooling of the product.The heat-lag effect of the film led to an increase in warpage of the product. |
