1、奇瑞車保險(xiǎn)桿燈座雙型腔注塑模設(shè)計(jì)說明書字?jǐn)?shù)：25518，本設(shè)計(jì)包括文件見上方文件夾預(yù)覽，如看不清楚，請(qǐng)另存至電腦查看摘 要隨著塑料工業(yè)的發(fā)展，塑料注塑模具的設(shè)計(jì)、加工和應(yīng)用已經(jīng)成為塑料制品加工的重要組成部分。本文設(shè)計(jì)的是奇瑞車保險(xiǎn)桿燈座雙型腔注塑模具。本次設(shè)計(jì)從課題的選擇依據(jù)、意義和國內(nèi)外發(fā)展現(xiàn)狀及前景入手，經(jīng)過對(duì)奇瑞車保險(xiǎn)桿燈座塑件的外形、尺寸等結(jié)構(gòu)的分析和對(duì)實(shí)際生產(chǎn)條件及現(xiàn)有加工技術(shù)的了解，從而選擇合理的塑件材料，選定合適的注塑機(jī)，確定合理的注塑模結(jié)構(gòu)。本次注塑模具的具體設(shè)計(jì)包括：模具分型面、型腔個(gè)數(shù)和布局的確定，凹凸模的機(jī)構(gòu)壁厚及型芯的尺寸計(jì)算，澆注、脫模、頂出、導(dǎo)向、排溢引氣、溫度調(diào)節(jié)

2、等系統(tǒng)的設(shè)計(jì)與計(jì)算。由于奇瑞車保險(xiǎn)桿燈座塑件表面存在側(cè)向通孔，所以本文還針對(duì)塑件的這一結(jié)構(gòu)特點(diǎn)，設(shè)計(jì)了獨(dú)特的側(cè)向抽芯機(jī)構(gòu)。最終依據(jù)以上各部分的設(shè)計(jì)、計(jì)算結(jié)果整理設(shè)計(jì)出奇瑞車保險(xiǎn)桿燈座雙型腔注塑模具整體結(jié)構(gòu)。關(guān)鍵詞：注塑模具；分型面；凹凸模；側(cè)向抽芯AbstractAs the plastic industry, plastic injection mold design and processing has become an important method of processing plastic products.

This design from the choice of topics based on significance and its current development status and prospects of starting, after a lamp on the Qirui car bumper plastic shape, size and other structural analysis and the actual production conditions and the existing p

4、rocessing technology understanding to choose reasonable Plastic materials, selected injection molding machine, determine a reasonable injection mold. The specific design of injection mold include: mold parting surface, the cavity number and layout of the established model of the body wall and the co

5、ncave and convex type core size calculation, casting, mold release, ejector, guide, reset, row overflow entraining, temperature regulation, and system design and calculation. As the Qirui car bumper lamp plastic surface of the lateral hole, so this also for the plastic parts of the structure, design

6、 a unique side core pulling. Part of the design basis of the above, the results to design the structure of the overall structure of mold. Pursuant to these parts of the final design, integration design calculations Qirui car bumper lamp plastic injection mold the overall structure.Key words: Injecti
