摘要：塑料工業(yè)是當(dāng)今世界上增長最快的工業(yè)門類之一，而注塑模具是其中發(fā)展較快的種類，因此，研究注塑模具對了解塑料產(chǎn)品的生產(chǎn)過程和提高產(chǎn)品質(zhì)量有很大意義。

本設(shè)計介紹了注射成型的基本原理，特別是單分型面注射模具的結(jié)構(gòu)與工作原理，對注塑產(chǎn)品提出了基本的設(shè)計原則；詳細(xì)介紹了冷流道注射模具澆注系統(tǒng)、溫度調(diào)節(jié)系統(tǒng)和頂出系統(tǒng)的設(shè)計過程，并對模具強(qiáng)度要求做了說明；最后介紹了當(dāng)今世界上最為普及的三維CAD/CAM系統(tǒng)標(biāo)準(zhǔn)軟件PRO/ENGNEER的PROGRAM模塊，對導(dǎo)柱和導(dǎo)套進(jìn)行了參數(shù)化設(shè)計。

通過本設(shè)計，可以對注塑模具有一個初步的認(rèn)識，注意到設(shè)計中的某些細(xì)節(jié)問題，了解模具結(jié)構(gòu)及工作原理；通過對PROGRAM的學(xué)習(xí)，可以建立較簡單零件的零件庫，從而有效的提高工作效率。

Abstract: plastic industry is in the world grows now one of quickest industry classes, but casts the mold is development quick type, therefore, the research casts the mold to understand the plastic product the production processimproves the product quality to have the very big significance.

This design introduced the injection takes shape the basic principle, specially single is divided the profile to inject the mold the structurethe principle of work, to cast the product to propose the basic principle of design; Introduced in detail the cold flow channel injection evil spirit mold pours the system, the temperature control systemgoes against the system the design process,has given the explanation to the mold intensity request; Finally introduced now in the world the most popular three dimensional CAD/CAM system standard software PRO/ENGNEERs PROGRAM module,led the wrap to the guide pillar to carry on the parametrization design.

Through this design, may to cast the mold to have a preliminary understanding, notes in the design certain detail question, understands the mold structurethe principle of work; Through to the PROGRAM study, may establish the simple components the components storehouse, thus effective enhancement working efficiency.

Key word: The plastic mold;the parametrization; inlays;divides the profile

1.1 模具工業(yè)在國民經(jīng)濟(jì)中的地位

模具是制造業(yè)的一種基本工藝裝備，它的作用是控制和限制材料（固態(tài)或液態(tài)）的流動，使之形成所需要的形體。用模具制造零件以其效率高，產(chǎn)品質(zhì)量好，材料消耗低，生產(chǎn)成本低而廣泛應(yīng)用于制造業(yè)中。

模具工業(yè)是國民經(jīng)濟(jì)的基礎(chǔ)工業(yè)，是國際上公認(rèn)的關(guān)鍵工業(yè)。模具生產(chǎn)技術(shù)水平的高低是衡量一個國家產(chǎn)品制造水平高低的重要標(biāo)志，它在很大程度上決定著產(chǎn)品的質(zhì)量，效益和新產(chǎn)品的開發(fā)能力。振興和發(fā)展我國的模具工業(yè)，正日益受到人們的關(guān)注。早在1989年3月中國政府頒布的《關(guān)于當(dāng)前產(chǎn)業(yè)政策要點(diǎn)的決定》中，將模具列為機(jī)械工業(yè)技術(shù)改造序列的第一位。

模具工業(yè)既是高新技術(shù)產(chǎn)業(yè)的一個組成部分，又是高新技術(shù)產(chǎn)業(yè)化的重要領(lǐng)域。模具在機(jī)械，電子，輕工，汽車，紡織，航空，航天等工業(yè)領(lǐng)域里，日益成為使用最廣泛的主要工藝裝備，它承擔(dān)了這些工業(yè)領(lǐng)域中60％~90％的產(chǎn)品的零件，組
