摘   要：

     塑料工業(yè)是當(dāng)今世界上增長(zhǎng)最快的工業(yè)門(mén)類(lèi)之一，而注塑模具是其中發(fā)展較快的種類(lèi)，因此，研究注塑模具對(duì)了解塑料產(chǎn)品的生產(chǎn)過(guò)程和提高產(chǎn)品質(zhì)量有很大意義。
本設(shè)計(jì)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(duì)注塑產(chǎn)品提出了基本的設(shè)計(jì)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(jì)過(guò)程，并對(duì)模具強(qiáng)度要求做了說(shuō)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(duì)導(dǎo)柱和導(dǎo)套進(jìn)行了參數(shù)化設(shè)計(jì)。
通過(guò)本設(shè)計(jì)，可以對(duì)注塑模具有一個(gè)初步的認(rèn)識(shí)，注意到設(shè)計(jì)中的某些細(xì)節(jié)問(wèn)題，了解模具結(jié)構(gòu)及工作原理；通過(guò)對(duì)PROGRAM的學(xué)習(xí)，可以建立較簡(jiǎn)單零件的零件庫(kù)，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 process and improves 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 structure and the 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 system and goes against the system the design process, and 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/ENGNEER's PROGRAM module, and 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 structure and the 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
