垃圾桶塑料模具設(shè)計,垃圾桶,塑料,模具設(shè)計 XX大學學士學位論文 摘 要 由于塑料具有許多金屬和其它非金屬所無法比擬的優(yōu)點, 所以近年來發(fā)展尤為迅速。在現(xiàn)代工業(yè)和日用產(chǎn)品中，越來越多的塑料制品代替了以往的多類產(chǎn)品，而模具作為塑件的成型技術(shù)也得到了迅速發(fā)展。 此論文在第一章緒論中主要介紹了塑料模具現(xiàn)階段的發(fā)展狀況，在現(xiàn)代模具設(shè)計中采用了大量的新技術(shù)，新工藝和新材料。模具設(shè)計已經(jīng)成為一種綜合型技術(shù)。還簡單的介紹了塑料的一般成份及塑料的一些特性。還介紹了注射模具的主要組成部件（如定模板、動模板、復位桿、頂桿、導柱等）及模板的材料選擇。 第二章第一節(jié)中寫的是塑料的注塑成型工藝，包括塑料的注塑成型工 藝、注塑成型參數(shù)的選擇（溫度、壓力和時間）。第二節(jié)介紹的是塑料制 品的設(shè)計及設(shè)計中應(yīng)考慮的因素。塑料制品設(shè)計的主要內(nèi)容包括塑料制品 的幾何形狀、尺寸精度和表面質(zhì)量。 在第三章塑料模具的設(shè)計中介紹了塑料模具設(shè)計的基礎(chǔ)知識包括：注 射模具的分類、注射模具與注射機的關(guān)系（基本技術(shù)參數(shù)和選用注射成型 機時基本工藝參數(shù)的校核）、澆注系統(tǒng)的設(shè)計、成型零件的結(jié)構(gòu)設(shè)計（模具分型面的選擇和凹模、凸模、型芯的設(shè)計及組合形式）。后三節(jié)是由三個零件的注射模具的設(shè)計過程。每個零件的設(shè)計步驟一般由產(chǎn)品分析及零件選擇、塑件幾何特性分析、注射成型機的選擇、注射成型機參數(shù)的校核、澆注系統(tǒng)的設(shè)計、成型零件的機構(gòu)設(shè)計、成型零件的尺寸、加熱冷卻裝置的設(shè)計及模具的零件等組成。 關(guān)鍵詞　塑料；注塑成型工藝；塑料模具；注射機 Abstract Because the plastics have many advantages that the metals and other nonmetals with for can't compare to, it developed quickly these yeas. In the modern industry and the articles for daily use, more and more plastic products replaced many products of former, and the mould as the technique of mould for plastic also got the quick development. This thesis introduced the current development in mould in plastics condition primarily in an introduction, adopting a flood of new technique in modern mould design, new craft with new material. The mould design has become a kind of synthesizing the type technique. Still introduced the general composition of the plastics and the some characteristic of the plastics in brief. Still introduced to inject the mould to constitute the material choice between parts( if settle the template, move the template, reply a pole, crest pole and lead pillar etc.) and template primarily. It write in the second a first knot of is a plastics to note the plastics mould the craft, including the plastics note the plastics mould the work craft, note the choice that plastics mould parameter.( Temperature, pressure with time) an introductive is a plastics system design and designs of the article inside should the factor of the consideration. The main contents that plastics ware design includes the plastics ware of several why shape, size accuracy with surface quantity. Introduced in the design of a plastics mould the foundation knowledge of the plastics mould design include: Note inject the classification of the mould and inject the mould with the relation that inject machine( basic technique parameter with choose to use to inject to mould The school core of the basic craft in hour in machine parameter), sprinkle the design that note the system, Mould the construction design of the spare parts( the mould divides the choice of the type with the cave mould, convex mould, type of design and combination form).Empress three the section be injected by three spare parts the design process of the mould makes .The design step of each spare parts is general to be analyzed by product and the spare parts choice, the piece of plastics is several why the characteristic analyzes and note inject the choice that mould the machine, inject the school core that mould the machine parameter, sprinkle the design that note the system and mould the spare parts The organization design, mould the size of the spare parts and heat the design of the cooling device and the spare parts of the mould etc. Keywords plastics； the craft that plastics of injecting model； plastics mould；inject machine 不要刪除行尾的分節(jié)符，此行不會被打印 - III - 目 錄 摘要 I Abstract II 第1章 緒論 1 1.1 塑料模具的發(fā)展狀況 1 1.2 注射模具設(shè)計簡要 2 第2章 塑料的成型工藝 4 2.1 注塑成型工藝 4 2.1.1 注射成型 4 2.1.2 注射成型工藝 4 2.2 塑料制品的設(shè)計 7 2.2.1 塑料制品的幾何形狀 7 2.2.2 塑料制品的尺寸精度 9 2.2.3 塑料制品的表面質(zhì)量： 10 第3章 塑料注射模具設(shè)計 11 3.1 塑料注射模具設(shè)計基礎(chǔ)知識 11 3.1.1 注射模具分類 11 3.1.2 注射模具與注射機的關(guān)系 12 3.1.3 澆注系統(tǒng)設(shè)計 12 3.1.4 成型零件的結(jié)構(gòu)設(shè)計 18 3.2 塑料注射模具設(shè)計 20 3.2.1 注射機的選擇 22 3.2.2 模具材料的選擇 24 3.2.3 成型收縮及尺寸計算 25 3.2.4 抽芯機構(gòu)設(shè)計 26 3.2.5 強度計算 29 3.3 塑料注射模具零件設(shè)計 30 3.3.1 模具零件設(shè)計 30 3.3.2 模具裝配圖 33 第4章 UG 35 4.1 UG介紹 35 4.2 UG特點 35 4.3 UG的工作界面 36 4.4 動畫創(chuàng)建的一般過程 37 結(jié) 論 41 致謝 42 參考文獻 43 附錄 45 - 5 -
