In the domestic market, plastic mold injection mold greatest demand, which is focused on the development of plastic mold. Injection molding is an important method of plastic molding, it is mainly suitable for thermoplastic molding, forming a complex shape can be precision plastic parts. The subject is flowers covered plastic molding process and mold design, injection mold knowledge as the basis to explain the plastic injection mold design process.(1) through the use of plastic mold design guidelines, mechanical drawing, interchangeability and measuring technology 673A mechanical principle and parts, mold materials and heat treatment, mold manufacturing process, the plastic molding process and die design and other aspects of the necessary basic knowledge and expertise, plastic mold design analysis and solve problems, to further consolidate and deepen the knowledge learned to open up(2) The design of injection mold design flowers cover plugs, the use of UG software was solid modeling plastic parts, plastic parts for the structure analysis process. Clear design ideas, determine the injection molding process and the various specific parts of a detailed calculation and verification. Such a structure designed to ensure reliable use of mold work to ensure coordination with other components. Finally, draw a mold assembly drawings and parts drawing with autoCAD(3) by calculating, mapping and the use of technical standards, specifications, design manual and other relevant design sheets, plastic design comprehensive basic skills training, and lay a good foundation for the practice of graduation design.(4) This paper cup through the juicer barrel injection mold design, to consolidate and deepen the knowledge, and achieved satisfactory results, to achieve the desired design intent.Key words: plastic mold; injection molding; mold design 目 錄第一章 前言11.1課題背景1第二章 塑件分析32.1 產(chǎn)品分析及其技術(shù)條件32.2塑件的結(jié)構(gòu)工藝性分析3第三章 成型布局及注塑機選擇53.1計算塑件的體積和質(zhì)量53.2 型腔的布局及成型尺寸53.3注塑機的選擇和校核63.3.1注射膠量的計算63.3.2 鎖模力的計算63.4.3 注塑機選擇確定7第四章 注塑模具設(shè)計94.1模架的選用94.1.1模架的類型94.1.2 模架的選擇94.1.3型腔模板的計算104.1.4.確定模板周界尺寸114.1.5.注射機參數(shù)校核114.1.5導(dǎo)向與定位機構(gòu)設(shè)計134.2分型面的設(shè)計144.3 澆注系統(tǒng)的設(shè)計144.3.1 主流道設(shè)計154.4 成型零部件的設(shè)計154.4.1 成型零部件結(jié)構(gòu)154.4.2.型芯和型腔的工作尺寸計算154.4.3中心距工作尺寸計算194.4.4 凹模寬度尺寸的計算194.4.5 凹模長度尺寸的計算204.4.6 凹模高度尺寸的計算204.4.7 凸模寬度尺寸的計算204.4.8 凸模長度的計算204.4.9 凸模高度尺寸的計算204.5.脫模及推出機構(gòu)214.5.1脫模力214.5.2 推出機構(gòu)214.6冷卻系統(tǒng)的設(shè)計與計算234.6.1 冷卻水道設(shè)計的要點234.6.2 冷卻水道在定模和動模中的位置244.6.3 冷卻水道的計算244.7 模具與注射機安裝模具部分相關(guān)尺寸校核25總結(jié)27參考文獻(xiàn)28致謝29沈陽化工大學(xué)科亞學(xué)院學(xué)士學(xué)位論文 致謝
