| 摘 要： | 研究了电加热快速热循环注塑工艺原理和模具结构，构建了电加热注塑模具的二维和三维热响应分析模型，分析获得了加热过程和冷却过程中模具型腔表面的热响应规律和温度分布规律，探讨了模具结构、加热元件和模具材料等因素对模具热响应效率和温度均匀性的影响。加热阶段，模具型腔表面的平均升温速率可达3．3℃／s，经过70S加热，模具表面可升高至250℃左右；冷却阶段，熔体的平均降温速率约为3．6℃／s。

| Abstract: | Electric heating rapid heat cycle molding technical principle and mould structure was studied. Both 2D and 3D models for thermal response analysis of the electric heating in- jection mould were built. The temperature response and distribution of the mould cavity sur- face during heating process and cooling process were obtained. Effects of the factors inclu- ding mould structure, heating element and mould material on the thermal response and tem- perature uniformity of the cavity surface were also discussed. During heating process, the average heating rate of the mould cavity surface can be 3.3 ℃/s. After 70 seconds heating, the temperature of the mould cavity surface can be about 250 ℃/s. During the cooling sur- face, the average cooling rate of the melt can be about 3.6 ℃/s. |
