热板式活络模具与蒸锅式活络模具的传热性能分析

Heat Transfer Performance Analysis of Hot Plate Type Segment Mold and Steamer Type Segment Mold

利用Ansys Workbench的瞬态热模块对圆锥面导向的热板式活络模具与蒸锅式活络模具进行传热性能对比分析,并对蒸锅式活络模具的结构进行优化。结果表明:蒸锅式活络模具的温模时间比热板式活络模具更短,但热板式活络模具的花纹块最大温差比蒸锅式活络模具小,温度分布更加均匀;结构优化后蒸锅式活络模具的花纹块最大温差、块上下侧温差以及中部横向温差均减小,温度分布更加均匀。

Using the transient thermal module of Ansys Workbench,a comparative analysis of the heat transfer performance of conical surface guided hot plate type segment mold and steamer type segment mold was carried out,and the structure of the steamer type segment mold was optimized.The results showed that the mold warming time of the steamer type segment mold was shorter than that of the hot plate type segment mold,but the maximum temperature difference of the pattern block of the hot plate type segment mold was smaller than that of the steamer type segment mold,and the temperature distribution was also more uniform.After structural optimization,the maximum temperature difference of the pattern block,the temperature difference between the upper and lower sides and the temperature difference of the middle transverse direction of the steamer type segment mold were all reduced,resulting in a more uniform temperature distribution.
