注塑模具异形冷却水道Moldflow优化设计作者：朱明 朱荣华 唐维雄 陈新来源：《科技创新与应用》2018年第12期 摘 要：注塑模具冷却水道受加工方法的限制，塑件在冷却过程中易产生热点，使产品冷却不均匀而引变形和表面质量问题。采用3D打印技术制造的模具，其内部异形冷却水道更靠近模具的冷却表面，从而提高了热量转移到冷却水的效率。基于Moldflow模拟软件对传统的冷却水道设计和随形冷却水道设计进行了模具和产品温度场、冷却时间的对比，从而为冷却水道的优化设计提供依据。 关键词：异形冷却水道；Moldflow；随形冷却；3D打印

Abstract： The cooling water channel of injection mould is limited by the processing method， and the plastic parts are apt to produce hot spots in the cooling process， which makes the product cooling uneven and causes deformation and surface quality problems. T
he mold made by 3D printing technology， whose internal special cooling channel is closer to the cooling surface of the mould， improves the efficiency of heat transfer to cooling water. Based on Moldflow simulation software， the design of traditional cooling channel and the design of conformal cooling channel are compared in terms of the mold and product temperature field and cooling time， thus providing the basis for the optimization design of cooling channel.
