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(duì)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。
本論文介紹了注射成型的基本原理，特別是雙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)過程，并對(duì)模具強(qiáng)度要求做了說明。設(shè)計(jì)成型零部件以及設(shè)計(jì)合理的推出機(jī)構(gòu)。對(duì)設(shè)計(jì)進(jìn)行驗(yàn)證主要是對(duì)注射機(jī)的相關(guān)重要參數(shù)進(jìn)行驗(yàn)證，包括模具閉合厚度、模具安裝尺寸、模具開模行程、注射機(jī)的鎖模力等。在校驗(yàn)合格后，進(jìn)行成型零件加工工藝過程的制定，既要保證塑件的質(zhì)量，又要兼顧經(jīng)濟(jì)性。
最后則是模具的裝配環(huán)節(jié)，包括制定裝配步驟、明確注意事項(xiàng)等。通過本設(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)問題，了解模具結(jié)構(gòu)及工作原理；通過對(duì)AutoCAD的學(xué)習(xí)，可以建立較簡(jiǎn)單零件的零件庫，從而有效的提高工作效率。

Plastic injection mold design shell

ABSTRACT

Plastic industry is grow now one of quickest industry classes in the world, 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. Design shaped parts，reasonable drawing mechanism and so on．
The design should be certification．Primarily related to the injection machine of important parameters for the certification including die close thickness sizes，the name distance，injection machine of the die draw force and so on．After，qualified in check，the molding parts machining process design must ensure that the quality of Supervision taking into account the economy．
Final assembly is part of the mold，which including the design of assembly steps，clear proceeding required attention．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.
