英语翻译
The plastic injection molding is a complex and highly efficient process to produce a large variety of thermoplastic products.The product quality is determined principally by the mold design.Within many design parameters,the number of gates and their locations have great effect on the product quality.It is necessary to optimize the number of gates and their locations to improve the quality of injection-molded products.Several studies reported have investigated the optimization of the injection molding process.Pandelidis I and Zhou Q[1] presented the optimization of gate location using the combined scheme of a simulated annealing and a hill-climbing method.The quality of a gating design was presented as an additive function of a temperature differential term,an overpacking term and frictional overheating term,with appropriate weighting term.Young W B[2] developed a method of gate location optimization based on the minimization of the mold filling pressure,uneven filling pattern,and temperature difference during the mold filling process.The genetic algorithm was used to search the optimal gate location.Irani R K et al.[3] developed a system that perform the gate design in two stages:global search followed by a local search.The limitation of this system is that the features used are of very simple geometry.

塑料注塑复杂、高效,是一种生产大量各式各样的热塑性塑料制品的工艺.制品的质量主要取决于模具设计.在模具设计需要考量的因素中,浇口的数量及其位置对制品质量有重大的影响.因此,有必要优化浇口的数量和位置,以改善注塑制品的质量.有几篇已报道的研究论文​对优化注塑工艺进行了考察.Pandelidis I 和周Q[1]提出采用模拟退火和爬山算法相结合的方案,来优化浇口位置.浇口设计的好坏,由一个包含温度微分项、过保压项、摩擦产生的过热项,以及相应的权重系数项组成的加法式来表达.Young W B [2]基于最小化的模具充填压力、不平衡充填方式、和模具充填过程中的温度差异,发展出了一种浇口优化方案.遗传算法被用来查找最佳的浇口位置.Irani R K et al.[3]开发出了一套系统,分两步来进行浇口设计：全局搜索和随后的局部查找.这套系统的局限性在于所使用的特征都是简单的几何体.
