摘   要

 本設(shè)計(jì)詳細(xì)地闡述了鈴蓋注射模具的參數(shù)化設(shè)計(jì)過程，給出了注射模具設(shè)計(jì)的基本步驟。在對(duì)產(chǎn)品進(jìn)行結(jié)構(gòu)分析和工藝分析的過程中，使用了UG,Mlodflow等工具來模擬注塑過程、分析成型過程中的參數(shù)變化、預(yù)測(cè)產(chǎn)品質(zhì)量和可能出現(xiàn)的缺陷。列出了注射機(jī)選擇的主要依據(jù)，并對(duì)主要參數(shù)進(jìn)行了校核。在模具的結(jié)構(gòu)設(shè)計(jì)的過程中，舉出了各部分設(shè)計(jì)時(shí)應(yīng)參照的公式，并結(jié)合本課題進(jìn)行了具體的分析。在分型面的選擇問題上，本設(shè)計(jì)列出了三種方案，通過分析比較，選擇了一種最佳方案。重點(diǎn)分析設(shè)計(jì)了溫度系統(tǒng)，說明了調(diào)溫系統(tǒng)對(duì)產(chǎn)品成型的重要性，通過軟件分析結(jié)合教科書最終確定散熱面積、冷卻水道直徑、冷卻水道長度等工藝參數(shù)。在設(shè)計(jì)完結(jié)構(gòu)后，對(duì)模具的安裝進(jìn)行了大致的說明，對(duì)模具的開合動(dòng)作做了必要的分析，對(duì)試模過程中可能出現(xiàn)的問題做了詳細(xì)的分析，并提出了相應(yīng)的解決方法。使用UG進(jìn)行三維造型貫穿整個(gè)設(shè)計(jì)過程，使設(shè)計(jì)變得很輕松，也可以及時(shí)地發(fā)現(xiàn)模具中的干涉等問題。

The mold design of bell cap injectinon
Abstract

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.
