摘 要

本設(shè)計(jì)論文系統(tǒng)闡述了汽車輪帽塑料注射模設(shè)計(jì)過(guò)程，根據(jù)汽車輪帽塑件的形狀和生產(chǎn)要求，編制汽車輪帽塑件的設(shè)計(jì)過(guò)程，初步制定了總體模具的設(shè)計(jì)方案。論文首先對(duì)汽車輪帽塑件進(jìn)行了詳細(xì)的工藝性分析，然后進(jìn)行注射模結(jié)構(gòu)設(shè)計(jì)，比如分型面的選擇，抽芯機(jī)構(gòu)的設(shè)計(jì)等，并進(jìn)行模具設(shè)計(jì)的相關(guān)的計(jì)算,完成型腔和型芯工作尺寸的計(jì)算等，接著對(duì)整個(gè)模具的進(jìn)行相關(guān)校核，最后完成整個(gè)汽車輪帽注射模設(shè)計(jì)，并繪制出模具的總裝圖和非標(biāo)準(zhǔn)件的零件圖。
本設(shè)計(jì)方案結(jié)構(gòu)緊湊，滿足制品大批量生產(chǎn)、高精度、外形復(fù)雜的要求，設(shè)計(jì)參考了以往注射模具的設(shè)計(jì)經(jīng)驗(yàn)，并結(jié)合制件性能，簡(jiǎn)化設(shè)計(jì)機(jī)構(gòu)，并且運(yùn)用AutoCAD等軟件進(jìn)行繪圖，縮短了生產(chǎn)周期，并且獲得良好的經(jīng)濟(jì)性能。

Abstract

The thesis systemic introduce the design process of the plastics injection mould of four-way pipe, base on the shape and the production requirement of four-way pipe, at the same time the article establish the design process of four-way pipe produce, and elementary set down the design scheme of the total injection mold. The four-way pipe produce adopt single cavity of injection mould design，use the mechanism of liquid pressure lateral loose core and incline leader lateral loose core,and the mechanism of handspike. First, the thesis analyse the craft of the four-way pipe produce particular, then finish the structure design of four-way pipe injection mold, such as the choice of the parting surface, the design of lateral loose core structure etc.. Second, the paper finish the calculatione related with the injection mold design, for example the calculation for the work size of the cavity and core. Third, the article complete the parametric relate with the whole injection molding checking. Finally, the thesis complete the design of the whole four-way pipe injection mold, and draw the total assembly chart and the accessory chart of the non-standard of the mold.
This design is compactness for fulfilling volume-produce, demand with complicated high accuracy and appearance, at the same time references anciently experience of injection mould and combines characteristic of produce to project organization simplify the project organization. In order to shor..
