Optimum Gate Design of FreeForm Injection Mould using the Abductive Network 基于Abductive网络的最佳任意注射模具浇口设计 J. C. Lin Department of Mechanical Design Engineering, National Hu-Wei Institute of Technology, Yunlin, Taiwan This study uses the injection position and size of the gate as the major control parameters for a simulated injection-mould. Once the injection parameters (gate size and gate position) are given, the product performance (deformation) can be accurately predicted by the abductive network developed. 本研究以注射位置和浇口的大小作为主要控制参数来模拟注射模具。一旦给出了喷雾参数(浇口大小和浇口位置,可用成熟的Abductive网络准确的预测产品性能(变形)。 To avoid the numerous influencing factors, first the part-line of the parameter equation is created by an abductive network to limit the range of the gate. The optimal injection parameters can be searched for by a simulation annealing (SA) optimization algorithm, with a performance index, to obtain a perfect part. 为了避免众多的影响因素,使用 abductive网络建立第一个线性参数方程来限制浇口的范围。用一个仿真退火算法优化算法计算出最优喷雾参数,用一个性能指标、获得一个完美的部分。 The major purpose is searching for the optimal gate location on the part-surface, and minimising the air-trap and deformation after part formation. This study also uses a practical example which has been and proved by experiment to achieve a satisfactory result. 主要目的是追求铸件浇注面上最优浇口的位置,最大程度的减少了铸件缩孔和变形形成。这研究也使用一个实际的例子, 实验证明结果令人满意。 Keywords: Abductive network; Injection mould; Simulation annealing (SA) 关键词:Abductive网络;注射模具;模拟退火算法 1. Introduction1。介绍 Owing to the rapid development of industry and commerce in recent years, there is a need for rapid and high volume production of goods. The products are manufactured using moulds in order to save the time and cost. Plastic products are the majority. Owing to these products not requiring complicated processes it is possible to cope with market demand speedily and conveniently. 近年来,由于工业的迅速发展,市场需要快速、大量生产的产品。公司产品全部使用模具可节省时间和成本。塑料制品占大部分，因为这些产品不需要复杂的过程，并能快速方便的应对市场的需求等特点。 In traditional plastic production, the designs of the portions of the mould are
