摘要
针对精密注塑模具冷却系统实际应用中存在的温度区域分布不均、冷却效率低等问题,对冷却管道结构、冷却介质循环装置以及温度控制系统进行了系统优化,阐述了鱼骨状分流管道、多级离心泵与模糊比例-积分-微分(Proportion Integration Differentiation,PID)温控方法的集成应用。实验结果显示,优化后型腔温度均匀性、冷却效率与产品尺寸稳定性均得到提高,冷却循环时间及温控响应速度满足生产需求,变形率和尺寸波动降低。
Aiming at the problems of uneven temperature distribution and low cooling efficiency in the practical application of precision injection mold cooling system,the cooling pipeline structure,cooling medium circulation device,and temperature control system were systematically optimized.The integrated application of“fishbone”shaped diversion pipeline,multi-stage centrifugal pump,and fuzzy Proportion Integration Differentiation(PID)temperature control method was elaborated.The experimental results show that the optimized cavity temperature uniformity,cooling efficiency,and product size stability have all been improved.The cooling cycle time and temperature control response speed meet the production requirements,and the deformation rate and size fluctuations are reduced.
