摘要 本次設(shè)計(jì)課題是塑料掛鉤注塑模具設(shè)計(jì)，主要包括模具總體結(jié)構(gòu)及其主要零部件的設(shè)計(jì)，以及模具各設(shè)計(jì)部分的計(jì)算與校核，并借助于PROE/UG/CAD軟件來進(jìn)行模具的繪制與分析計(jì)算。本次設(shè)計(jì)最突出的地方在于運(yùn)用PROE/UG/CAD軟件，在三維空間環(huán)境中進(jìn)行模具設(shè)計(jì)過程。從零件建模到模具的結(jié)構(gòu)設(shè)計(jì)以及最后的出圖，均通過PROE/UG/CAD來進(jìn)行；同時(shí)，在設(shè)計(jì)過程中進(jìn)行了如澆注系統(tǒng)的分析，開模動(dòng)作檢測(cè)等工作，以設(shè)計(jì)出最為合理的結(jié)構(gòu)。此外，設(shè)計(jì)中大部分分析都依靠軟件進(jìn)行，對(duì)于模具一些結(jié)構(gòu)形式的選擇及其計(jì)算校核則依靠人工計(jì)算，大大縮短了模具設(shè)計(jì)花費(fèi)在創(chuàng)建，選擇和細(xì)化模架部件以及模具組件上的時(shí)間，從而使設(shè)計(jì)周期大大縮短，較好的保證了該模具的設(shè)計(jì)水平。本次設(shè)計(jì)較好的實(shí)現(xiàn)了CAD/CAE/CAM技術(shù)對(duì)復(fù)雜，精密塑件的設(shè)計(jì)。

Abstract This design topic is linked to plastic injection mold design of hook and the mold design mainly includes the overall structure and main parts, and the calculation and check of the design of mold parts.And with the help of PROE/UG software, the analysis and drawing die structure are carried out. The characteristics of this design is the use of PROE/UG software to design the process in 3Denvironment.The modeling,the structure design of the part and the final drawing are carried out through PROE/UG/CAD;.At the same time, in order to design the most reasonable mould structure ,the analysis of gating sisterm,the mold movement detection and interference detection work are carried out in the design process. In addition, the designs of most analysis rely on software,but some structure form selection and calculation are based on manual, which can greatly reduce the mold design is spend in creating, customizing and refinement of mold parts and mold assembly time. Therefore,the design cycle is greatly shortened, and the design level of the die design thecan be guaranteed. The better design can be produced in this mold design by CAD/CAE/CAM for complex, design of precision plastic parts.
