【正文】 畢業(yè)設(shè)計(jì)（論文 ） 題目： 茶杯蓋 注射模具設(shè)計(jì) 作 者 XXX 屆 別 XXX 系 別 機(jī)電系 專 業(yè) 機(jī)械設(shè)計(jì)及其自動(dòng)化 指導(dǎo)教師 XXX 職 稱 XXX 完成時(shí)間 2021年 5月 6日 摘要 塑料在當(dāng)今世界上無(wú)處不用 ，因此塑料模具有很大發(fā)展，特別是注塑模。由此可知，研究注塑模具對(duì)了解塑料產(chǎn)品的生產(chǎn)過(guò)程和提高產(chǎn)品質(zhì)量有很大意義。 本課題主要是針對(duì)瓶蓋的模具設(shè)計(jì) ,通過(guò)對(duì)塑件進(jìn)行工藝性分析和比較 ,最終設(shè)計(jì)出一副注塑模。該課題從產(chǎn)品結(jié)構(gòu)工藝性及具體模具結(jié)構(gòu)出發(fā)，對(duì)模具的澆注系統(tǒng)、模具成型部分的結(jié)構(gòu)、頂出系統(tǒng)、冷卻系統(tǒng)、注塑機(jī)的選擇及有關(guān)參數(shù)的校核、都有詳細(xì)的設(shè)計(jì)，同時(shí)并簡(jiǎn)單的編制了模具的加工工藝。通過(guò)整個(gè)設(shè)計(jì)過(guò)程表明該模具能夠達(dá)到此塑件所要求的加工工藝。根據(jù)題目設(shè)計(jì)的主要任務(wù)是茶杯蓋注塑模具的設(shè)計(jì)。也就是設(shè)計(jì)一副注塑模具來(lái)生產(chǎn) 茶杯蓋的塑件產(chǎn)品，以實(shí)現(xiàn)自動(dòng)化提高產(chǎn)量。 通過(guò)本設(shè)計(jì)，可以對(duì)注塑模具有一個(gè)較深的認(rèn)識(shí)，注意到設(shè)計(jì)中的某些細(xì)節(jié)問(wèn)題，了解模具結(jié)構(gòu)及工作原理；通過(guò)對(duì) PROGRAM 的學(xué)習(xí)，可以建立較簡(jiǎn)單零件的零件庫(kù)，從而有效的提高工作效率；通過(guò)畫裝配圖、零件圖，進(jìn)一步系統(tǒng)深化CAD 熟練程度，加深了對(duì)模具各個(gè)零件的認(rèn)識(shí)。 關(guān)鍵字 : 塑料模具，注射機(jī)，型腔，澆注系統(tǒng) Abstract Plastic is everywhere in the world today with , Therefore has great development prospects of plastic , especially in Injection Molding ,so the study of plastic injection molds for understanding the production process and improve the quality of products have great significance. This topic mainly aims at bottle cap39。s mold design, Through to models to carry on the technological analysis and the parison , This topic embarks from the product mix technology capability and the concrete mold structure , To mold39。s gating system, the mold formation part39。s structure, goes against the system, the cooling system, injection molding machine39。s choice and the related parameter examination, has the detailed design, Simultaneously and simple establishment mold39。s processing craft. Through the entire design process indicated that this mold can achieve this to model the processing craft which an institute requests. Is the teacup covers injection mold39。s design according to the topic design39。s primary mission. Is also designs an injection mold to produce the teacup to cover models a product, realizes the automation to raise the output Through the design, injection mold can have a deeper understanding of the design notes that some of the details to understand the structure and working principle of learning PROGRAM, you can create a simpler ponents parts store, and effective improve efficiency。 through painting assembly drawing, part drawings, and further deepen the CAD system proficiency, a better understanding of the various parts of mold.
