本文提出了一种新的注塑件三维分型线搜索方法。在以往的工作中，分型线的自动搜索通常是基于曲面边环的。然而，在特定的分型位置可能不存在边环。在本研究中，所有的表面在一个初始的实体模型分为联合分型面和多分型面。在分型线搜索之前，采用离散模型法将多个分型面分解为若干个联合分型面，生成新的分型面边作为潜在分型线。基于纯并集分型面模型完成分型线搜索。案例研究表明，本研究解决了以往工作中面临的一些共性问题。
Abstract This paper presents a new approach for three-dimensional parting line search of injection moulded parts. In previous work, automatic parting line search is usually based on surface edge-loops. However, it is possible that edge-loops may not be present in a particular parting location. In the present research, all the surfaces in an initial solid model are divided into union parting surfaces and multiple parting surfaces. The multiple parting surfaces are decomposed into several union parting surfaces using the discrete model method before parting line search, creating the new edges as potential parting lines. Parting line search is completed based on the pure union parting surface model. Case studies show that the present research has solved some of the common problems faced in the previous work.
