摘要
虽然冷却水道较好的解决了传统冷却水道冷却不均匀的问题,但是在设计和制造过程中还是存在很多问题。以典型的盖帽注塑件为研究对象,设计了五种随形冷却水道方案,通过Moldflow模拟软件进行分析比较,得出冷却效果最佳的方案,并利用选择性激光融化(SLM)技术制造出带有随形冷却水道的模具镶件并进行注塑实验。结果表明,与传统冷却水道相比,最佳方案冷却时间缩短1.2%,最高温度减小2.9℃,温度均匀性提高58.3%,同时冷却均匀性非常好,而冷却水压压力增加14.95bar。利用SLM工艺制作该镶件仅需10h,且成型质量好,内部结构清晰,应用于注塑模具的效果良好。
The conformal cooling channel is a better solution to the problem of the uneven cooling of the traditional cooling wa- ter channel, but there are many problems in design and manufacture. In this paper, use the typical cap injection as research ob- ject, five types of conformal cooling channel schemes were designed. The design scheme of the best cooling effect have been gotten through the Moldflow simulation software to analyze and compare. And the Selective laser melting(SLM) technology is used to fabricate the mold insert with the conformal cooling channel. The results show:compared with the traditional cooling water channel, the best design schemers cooling time is shortened by 1.2% with maximum temperature reducing by 2.9 ~Cand temperature uniformity improving by 58.3~, meanwhile, it have a good cooling uniformity. But cooling water pressure in- creased by 14.95 bar. By using SLM process, the mold insert with good quality and clear internal structure was fabricated in 10 hours and it can completely be applied to the injection molding.
