摘  要

近幾年好多國(guó)家都在發(fā)展機(jī)械行業(yè)，與機(jī)械相關(guān)的各個(gè)行業(yè)都越來(lái)越重視CAD/CAM技術(shù)，如今CAD/CAM技術(shù)已發(fā)展成為一項(xiàng)比較成熟的共性技術(shù)，我國(guó)家電工業(yè)的高速發(fā)展對(duì)模具工業(yè)，尤其是塑料模具提出了越來(lái)越高的要求,國(guó)內(nèi)塑料模具市場(chǎng)以注塑模具需求量最大，其中發(fā)展重點(diǎn)為工程塑料模具。同時(shí)還因?yàn)樗芰现破芳澳＞叩?D設(shè)計(jì)與成型過(guò)程中3D分析正在塑料模具工業(yè)中發(fā)揮越來(lái)越重要的作用。 

在本次畢業(yè)設(shè)計(jì)中，通過(guò)運(yùn)用三維實(shí)體造型高端軟件UG NX對(duì)“溫控器墊塊”外形進(jìn)行3D造型，同時(shí)也設(shè)計(jì)了其塑料注塑模的3D模型。在正確分析塑件工藝特點(diǎn)和ABS的性能的基礎(chǔ)上，介紹了對(duì)凸模，凹模，澆注系統(tǒng)，脫模機(jī)構(gòu)，頂也機(jī)構(gòu)的設(shè)計(jì)，選擇標(biāo)準(zhǔn)零件，設(shè)計(jì)非標(biāo)件的設(shè)計(jì)過(guò)程。由于模具生產(chǎn)的塑料制品具有高精度、高復(fù)雜程度、高一致性、高生產(chǎn)率和低消耗等特點(diǎn)，涉及模具結(jié)構(gòu)、強(qiáng)度、壽命計(jì)算及熔融塑料在模具中流動(dòng)預(yù)測(cè)等復(fù)雜的工程運(yùn)算問(wèn)題；CAD、UG NX等不同的軟件可分別用于模具的設(shè)計(jì)、制造和產(chǎn)品質(zhì)量進(jìn)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(diǎn)是模具先由注射機(jī)合模機(jī)構(gòu)閉和緊密，然后由注射機(jī)注射裝置將高溫高壓的塑料熔體注入模腔內(nèi)，經(jīng)冷卻或固化成型后，在側(cè)向分型的作用下開模取出塑件。還根據(jù)所設(shè)計(jì)的模具尺寸選擇安裝了相應(yīng)的模架，最終生成了直觀的結(jié)構(gòu)設(shè)計(jì)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.

Key words:Thermostat;plastics mold;CAD/CAM;ABS plastic;Three-Dimensional
