摘要
以叶轮塑件为研究对象,采用不同的方案进行随形冷却水道的设计,利用Moldflow软件对各种方案进行模流分析,选出冷却效果最优的冷却方案;然后根据所确定的冷却方案进行随形冷却水道和型腔的设计,并基于3D打印技术选择性激光熔化(SLM)进行加工制造,得到随形冷却水道与型腔一体的模具镶件;最后完成整个模具的装配并进行注塑成型加工,进行模具型腔表面温度及镶件表面温度的测量以验证设计的可行性。
In this paper, different schemes were used to design the conformal cooling channel based on a plastic impeller as a research object, and Moldflow software was used to do mold flow analysis of plastic part for selecting the optimal cooling effect scheme. According to the cooling scheme, the eonformal cooling channel and cavity were designed, and a mold insert composed by conformal cooling channel and cavity was manufactured by selective laser melting （SLM） of 3D printing technology. Finally, the mold was assembled and the impeller was injection molded, and the temperatures of cavity wall and insert wall were measured for verifying the feasibility of design.
