摘　　要：在分析玻璃瓶罐产品结构与企业模具设计标准的基础上,在NX环境下提出基于模型检索的玻璃瓶模具组件设计方法。采用极半径不变矩的图像识别算法进行特征识别,以瓶罐产品信息作为侧向索引,构建了包含玻璃瓶模型特征以其对应模具组件方案的实例库。在实例库中对相似模型进行检索与匹配,再以系统知识库中的专家知识与经验对匹配成功的相关组件进行设计。以400 ml广口瓶的初型模和成型模设计案例验证了该设计方法的可行性。Based on the analysis on the structure of glass bottle product and the standard of mould design for enterprises,a method of glass bottle mould component design based on model retrieval is proposed on the NX software platform.Applying the image recognition algorithm of polar-radiusinvariant moment for feature recognition,a library case that contains features of glass bottle models and their corresponding scheme for mould component assembly is constructed with the index of bottle products.After retrieving and matching the most similar molds in the case library,the successfully-matched components are designed based on experts’knowledge and experience in the knowledge base of system.The feasibility of the design method turns out to be verified by the design example of the blank and blow mould of 400 ml jar in the article.
