摘 要
近幾年好多國家都在發(fā)展機械行業(yè)，與機械相關的各個行業(yè)都越來越重視CAD/CAM技術，如今CAD/CAM技術已發(fā)展成為一項比較成熟的共性技術，我國家電工業(yè)的高速發(fā)展對模具工業(yè)，尤其是塑料模具提出了越來越高的要求,國內塑料模具市場以注塑模具需求量最大，其中發(fā)展重點為工程塑料模具。同時還因為塑料制品及模具的3D設計與成型過程中3D分析正在塑料模具工業(yè)中發(fā)揮越來越重要的作用。
在本次畢業(yè)設計中，通過運用三維實體造型高端軟件UG NX對“溫控器墊塊”外形進行3D造型，同時也設計了其塑料注塑模的3D模型。在正確分析塑件工藝特點和ABS的性能的基礎上，介紹了對凸模，凹模，澆注系統(tǒng)，脫模機構，頂也機構的設計，選擇標準零件，設計非標件的設計過程。由于模具生產的塑料制品具有高精度、高復雜程度、高一致性、高生產率和低消耗等特點，涉及模具結構、強度、壽命計算及熔融塑料在模具中流動預測等復雜的工程運算問題；CAD、UG NX等不同的軟件可分別用于模具的設計、制造和產品質量進行分析。塑料注射成型所用的模具稱為注射模成型模具，該模具特點是模具先由注射機合模機構閉和緊密，然后由注射機注射裝置將高溫高壓的塑料熔體注入模腔內，經冷卻或固化成型后，在側向分型的作用下開模取出塑件。還根據(jù)所設計的模具尺寸選擇安裝了相應的模架，最終生成了直觀的結構設計圖；此外還利用CAD繪制了模具裝配圖以及各種成型零件圖。

Abstract
A lot of countries in the development of machinery industry in recent years, every industry pay more and more attention to related to mechanical CAD/CAM technology, CAD/CAM technology has now developed into a relatively mature technology, with the rapid development of our country home a ABS liance industry of mold industry, puts forward higher and higher requirements, especially plastic mould, in 2004, as a proportion of the plastic mold in the mold industry has risen to 30%, according to experts predict that in the next few years, China plastic mould industry will continue to maintain an annual growth rate of more than 10% of the high speed of development. Domestic demand in injection mold plastic mold market is the largest, the key for engineering plastic mold development. Also because of the plastic products and mould Three-Dimensional design and molding process of Three-Dimensional analysis is the plastic mold industry plays a more and more important role.
In this graduation design, the high-end software UG NX three-dimensional entity model is used to shape of "t type mounting bracket" Three-Dimensional modeling, and design the Three-Dimensional model of the plastic injection mold.On the basis of the correct analysis of the characteristics and ABS plastic parts process performance, the introduction of the punch,die,casting system, stripping agencies,top agency also design, selection of standard parts,the design of non-standard parts of the design process.Due to mold plastic products with high precision,high complexity,high consistency,high productivity and low consumption, etc,involve mold structure, strength,life span,and the molten plastic in the mold flow projections and other complex engineering computing problems; CAD,different software may be designed such UG NX molds are used,the manufacturing and product quality analysis.Plastic injection molding mold used for injection molding is called a mold injection machine is characterized first by a mold clamping mechanism and tightly closed, and then the injection machine injection device of the high temperature and pressure of the plastic melt into the mold cavity, cooling or after curing,in the role of the lateral parting remove mold plastic parts.Also according to the design of the mould size choose to install the corresponding mold frame, the resulting intuitive structure design; In addition to use CAD draw the mold assembly drawing as well as a variety of molding part drawing.
