面向压铸模浇道的变参数建模方法研究

摘要/Abstract

摘要： 针对压铸模浇道建模过程中遇到的几何特征重复生成时的繁琐性、操作过程的复杂性和设计参数的离散性等问题，提出以变参数为主导的浇道建模方法。该方法在浇道特征要求和实用技术基础上，通过对浇道变参数细节特征进行分析，以及浇道特征对金属溶液特性产生不同影响的研究，以UG8.0为研发平台并结合CAD技术，实现了压铸模浇道的参数化、系统化和标准化设计，开发出变参数压铸模浇道设计系统。该系统有效地实现了参数的集中处理，避免了用户的重复操作，缩短了浇道的设计周期，提高了设计精度。

Abstract: Aiming at the problems which were combined with the cumbersome of repeated generation of geometric characteristics, the complexity of operation and the discrete of design parameters during in the modeling of die casting, this paper proposed a modeling method with variable parameters as the dominant. Based on sprue's feature requirements and practical technology, and through the analyses of sprue's variable parameter characteristics the impacts of sprue's feature on the properties of metal solution were studied. Making UG8.0 as the research platform and combined with CAD technology, the parameterized, systematic and standardized design of die casting mould was realized to develop a variable parameters design system of die casting mold. The centralized processing of the parameters was effectively realized by this system, avoiding the repetitive work of designers, shorting thedevelopment cycle and improving the design accuracy.

Key words: die casting mould, sprue, variable parameter, computer aided design（CAD）
