摘要:注射成型是塑料成型的一種重要方法，它主要適用于熱塑性塑料的成型，可以一次成型形狀復(fù)雜的精密塑件。本課題就是將筆記本散熱支架作為設(shè)計模型，將注射模具的相關(guān)知識作為依據(jù)，闡述塑料注射模具的設(shè)計過程。利用UG軟件對塑件進行了實體造型， 通過對塑件的工藝分析，設(shè)計出塑料模具。 本畢業(yè)設(shè)計說明書首先介紹了模具設(shè)計與分類，然后對產(chǎn)品材料性能做了介紹，并初步選擇注塑機。 本說明書還詳細敘述了模具機構(gòu)方案，包括實體建模、確定分型面、成型零部件的結(jié)構(gòu)設(shè)計、脫模機構(gòu)、合模導(dǎo)向機構(gòu)、頂出機構(gòu)、澆注系統(tǒng)、冷卻系統(tǒng)等等的設(shè)計過程。接下來選擇了重要零件模具型腔，進行工藝分析并利用UG軟件對其進行模擬的NC數(shù)控加工。最后用AutoCAD繪制了一套模具裝配圖和零件圖，以及脫模過程示意圖。 本設(shè)計通過對筆記本散熱支架注射模具設(shè)計，鞏固和深化了所學(xué)知識，取得了比較滿意的效果，達到了預(yù)期的設(shè)計意圖，并積累了相關(guān)的設(shè)計意念與經(jīng)驗。 關(guān)鍵詞：塑料模具；注射成型；模具設(shè)計；數(shù)控加工
ABSTRACT:Plastic injection molding is an important method, which is mainly applied to the thermoplastic plastic molding, molding can be a complex shape of precision plastic parts. Is the topic of the notebook heat dissipation bracket as a design model, the injection mold-related knowledge as a basis, elaborates the design process of plastic injection mold. The use of software UG plastic parts for the solid modeling, plastic parts of the process analysis, design of plastic mold. The graduation design instruction booklet first introduced the mold design and classification, and then on the material properties of the product were introduced, and the initial choice of injection molding machine. The specification also describes in detail the mold mechanism scheme, including modeling, determine the face, forming parts of the structure design, demoulding mechanism, guide mechanism in mould clamping, ejecting mechanism, pouring system, cooling system and so on in the design process. Next select the important parts of the mold cavity, analysed the technology and use the UG software to simulate the NC CNC machining. Finally, AutoCAD mapping using a set of mold assembly drawing and parts drawing, as well as the stripping process sketch map. Through the design of the notebook heat dissipation bracket injection mold design, consolidate and deepen the knowledge, and achieved satisfactory results, to achieve the desired design intent, and the accumulation of the relevant design ideas and experience. Keywords: Plastic mould; The injection molding; Mold design ;NC machining
