| 摘 要: 对于热流道系统，将软管改为硬管可以节约成本，同时也提高了其外观及品质。但是，硬管的手工折弯导致装配成本更高，因此基于热流道3D模型开发一款插件，能够在三维软件中自动对热流道三维模型提取特征，程序自动生成硬管管道的最优路径。利用VB.NET对Solidworks进行二次开发，提取热流道系统的框架特征，运用迪杰斯特拉算法求解最短路径，最后将最短路径坐标以表格的形式显示在三维软件中。 |

| Abstract: Replacing hoses of hot runner system with hard pipes can save costs and improve the appearance and quality of the hot runner system. However, manual bending of hard pipes leads to higher assembly costs. This paper proposes to develop a plug-in based on the three-dimensional (3D) model of the hot runner, which can automatically extract features from the 3D model of the hot runner in the 3D software and generate optimal path of hard pipes. VB.NET is used to re-develop Solidworks, frame features of the hot runner system are extracted, and Dijkstra's algorithm is used to solve the shortest path. Finally, the shortest path coordinates in the form of a table is displayed in the 3D software. |
