摘 要 本设计详细地阐述了铃盖注射模具的参数化设计过程，给出了注射模具设计的基本步骤。在对产品进行结构分析和工艺分析的过程中，使用了UG,Mlodflow等工具来模拟注塑过程、分析成型过程中的参数变化、预测产品质量和可能出现的缺陷。列出了注射机选择的主要依据，并对主要参数进行了校核。在模具的结构设计的过程中，举出了各部分设计时应参照的公式，并结合本课题进行了具体的分析。在分型面的选择问题上，本设计列出了三种方案，通过分析比较，选择了一种最佳方案。重点分析设计了温度系统，说明了调温系统对产品成型的重要性，通过软件分析结合教科书最终确定散热面积、冷却水道直径、冷却水道长度等工艺参数。在设计完结构后，对模具的安装进行了大致的说明，对模具的开合动作做了必要的分析，对试模过程中可能出现的问题做了详细的分析，并提出了相应的解决方法。使用UG进行三维造型贯穿整个设计过程，使设计变得很轻松，也可以及时地发现模具中的干涉等问题。
The mold design of bell cap injectinon This paper has elaborated the injection mould parametric design of the Round Box, and mentioned the general steps of injection mould design. During plastic part analysis and structure analysis, MPA is used to simulate the filling process, analysis the parameters’ change during molding and forecast the filling quality. How to choose machine and check the main parameters is involved in this paper. During the structure design of the mold, the principle of each part is been listed out and analysised combining this title. The issue of designing parting plane, there list three programs and choose the best one at last. The determination of side core’s parameters is referenced to the method of oblique guide. The design points of the side core is listed out. The temperature adjusting system’s design and analysis is the focus in this paper. Here elaborated the importance of the temperature adjusting system, and detailed calculated the heat that enter and out the mold, then determined the parameters of cooling system. After the design of structure, this paper simply explains the assemble order, analyses the course of mold opening and closing. It analyses the problem that would appear during testing the mold and gives some blue print to solve those problem. UG is being used to built of three-dimensional model. It makes the design a easy work, and some problems like intervene has been found out in time.
