一种柔性的注塑模热流道设计系统

摘要

The hot runner of injection mould design is a time consuming and low automation level process.A design method based on sketch features merging is proposed for complex manifold plate design.This method decomposed a manifold plate into separate sketch features and reconstructed the manifold sketch by parametric drawing and automatic trimming with adjacent entities.Furthermore,the automatic assembly of hot runner accessories was finished by using the set assembly rules.The hot runner design system was developed on the SolidWorks platform.The application of this system shows that it has high efficiency and flexibility and is suitable for complex hot runner design.%目前注塑模热流道设计中存在设计工作量大、自动化程度不高的问题.针对复杂形状的分流板,提出了一种基于草图特征拼合的设计方法.该方法将分流板实体特征分解为对应的参数化草图特征,通过草图特征的参数化绘制和自动剪切,完成草图的绘制,并生成分流板零件.此外通过建立装配规则,实现了热流道配件的自动装配.该系统在SolidWorks平台下开发,实际应用表明该系统兼具效率和柔性,适用于复杂的热流道系统的设计.
