摘　　要： 模具是生产各种工业产品的重要工艺装备，现代工业中60％～90％的产品要靠模具生产。随着现代工业发展和产品更新换代周期急剧缩短，模具的需求量大幅度增加。另一方面，我国对国外先进模具技术的不断消化吸收，使得模具工业水平与国外的差距愈来愈小，模具出口业务也日益增多。而模具报价是模具制造企业技术、经济、效率和管理的综合反映，是模具企业和客户接触的关键环节，也决定着企业能否获得订单并从中获利。市场经济条件下，客户对模具制造商的要求越来越高，企业之间的竞争日趋激烈，这些都使传统的依据经验进行报价的方法已不能满足现在的报价要求。随着现代社会计算机技术、网络技术以及数据库等高新技术的发展，开发一套能够满足实际报价要求的模具报价软件已成为模具制造商和客户所共同关心的问题。 本文围绕广东省关键领域重点突破项目“汽车大型精密复杂注塑模具数字化制造”/(项目编号：2004A10402001/)，选取以汽车保险杠模具为代表的大型注塑模为研究对象，开发了一套基于Web的大型注塑模报价系统，旨在给企业提供一种快速、准确地进行模具报价的工具。本文的主要工作包括以下几个方面： /(1/)分析了模具报价的常用方法和特点以及计算机辅助报价系统的研究现状，通过对模具价格构成的分析，总结了大型注塑模的制造特点以及价格构成与中小型注塑模的不同之处，构建了大型注塑模的价格构成公式。 /(2/)将模糊数学理论应用于模具报价中，构建了大型注塑模相似判断的一致矩阵并计算了各相似特征的权重值，实现了大型注塑模报价的模糊查询。 /(3/)应用Borland Delphi 7.0开发工具、Intraweb 7.2.10 Web开发组件和MSSQL Server 2000数据库平台，开发了基于Web的大型注塑� Molds//dies are significant technical equipments of producing various industrial products. In modern industry, about 60％～90％products are delivered by molds. With the developing of the modern industry and the sharp shortening of the period of products updating, the demand of molds and dies expands increasingly. On the other hand, we master foreign advanced technology of molds continuously. This makes the gap of mold industry smaller and smaller between our country and foreign countries. The export business is expanding. Molds-quotation is comprehensive reflection of technology、economy、efficiency and management of manufacturers of moulds. It is the first step that mould corporations come into contact with their customs, and also it is the critical aspect that determines whether the mold corporations can obtain the orders and get profit from the mold make. Customer's requirement gets higher and higher and the competition between corporations gets more and more drastic under the market economy condition. All about that make the quotation that calculated by experience can not satisfy the quotation require. So, developing a set of molds quotation software that can satisfying the practical quotation demands becomes common concern questions of the manufacturer of the molds and customer. The thesis is concerned mainly on the project of 'The digitized manufacture of car's large precise complex injection mold', which is a key industries project of the Guangdong province. On the basis of studying about the large injection mold like the fender-guard, we develop a set of Web-based large injection mold quotation system. It can offer a fast and accurate quotation to corporations. /(1/) The thesis analyses the method and characteristic of mold quotation and the present state of computer-aided-quotation. The differences between the manufacture characteristic and the cost construction of large injection mold and that of medium and small-sized injection mold are generalized by analyzing the cost construct
