【正文】 inch TV and some thickwalled shell mold parts using gasassisted technology, some of the Manufacturers also used the CMOLD gasassisted software, to achieve better results. Pres panies such as Shanghai New users will be able to provide gasassisted molding equipment and technology. Hot runner mold began to promote, some plants use rate of over 20%, the general formula or external heat hot hot runner system, a few units are in the world39。s advanced level of difficulty valve gate hot runner mold. But overall runner adoption rate of less than 10%, pared with 50% to 80% of the foreign countries, a big gap [2].2) Development of injection mold at home and abroadIn recent years, the plastics industry by leaps and bounds forward, mold design and manufacturing industry has also undergone a fundamental change. High efficiency, automation, largescale, ultrasmall, highprecision, high life of the mold in the share of the entire mold production the proportion is growing. According to statistics, cars, tractors, electrical appliances, instruments,Bicycles, refrigerators, fans, etc., respectively, 60%, 85% and 92% of the parts used mold forming. Cost mold production will account for 10% to 30% and gradually increase production costs. So Japan said mold is to enter the affluent society, the driving force behind German called Metal Processing king mold industry industrial countries has bee an independent industry, the mold technology as an important symbol of national machinery manufacturing technology level. The domestic plastic plastic parts and modern industrial production occupies a very important place in people39。s daily lives. Using molding process instead of the traditional cutting process, increase productivity, ensure part quality, material savings, reduce production costs, to obtain high productivity. Thus, in the mechanical and electrical, instrumentation, chemical, automotive, and aerospace and other fields, has bee a good alternative plastic material of metal and has been widely used, there has been a trend of metallic materials such as plastics. As one of the most effective plastic injection molding technology molding method it can have a shape and dimensions of the various structures of plex precision plastic parts. Molding cycle is short, high productivity, large production and low cost, easy to achieve the advantages of automated or automated production, etc. Therefore, the world production of plastic mold injection mold about half or more [2].In recent years, the rapid pace of development of its large demand is unprecedented, but pared with the industrialized countries are still large gaps in general. At present, China39。s mold industry is imperative to speed up technological progress, the adjustment of product structure, increase the proportion of highgrade mold, quality and efficiency of the improved degree of localization of the mold, reducing dependence on imported molds. Future domestic and foreign plastic mold manufacturing technology and molding technology has the following trends: 1) in the mold design and manufacture a wide range of applications in CAD / CAE / CAM technology。 2) highspeed milling will be more widely used。 3) in the plastic mold promote the use of hot runner technology, injection molding and highpressure injection molding technology。 4) improve the utilization of standardized levels of mold and mold standard parts。 5) research and application tooling speed measurement technology and reverse engineering。 6) virtualization technology will be developed。 research and development 7) mold automatic processing system. Widely used CAD / CAE / CAM technology, gradually integrated direction.附錄B原文注塑模具設計塑料工業(yè)是當今世界快速發(fā)展的行業(yè)之一是為數(shù)不多的數(shù)十億美元的工業(yè)生產(chǎn)。塑料制品在日常生活中為人們提供了極大的便利,包括肥皂箱供應幾乎是必不可少的。本文設計了一個肥皂盒,具有防水功能,能有效保護soap不被水弄濕,延長使用壽命的肥皂。注塑模具成型方法由于其效率高、精度高、低成本的生產(chǎn)各種各樣的產(chǎn)品復雜的形狀,是塑料制品生產(chǎn)手段的重要性。然而,面對全球化市場競爭,塑料工業(yè)面臨著巨大的壓力。為了縮短產(chǎn)品設計周期,提高產(chǎn)品質(zhì)量,將各種先進的生產(chǎn)模式是用于注塑模具的設計是時代的潮流,如CAD / CAM / CAE集成技術(shù)。本文從圖中可以看出,塑料碎片屬于薄壁腔產(chǎn)品、投影面積最高的飛機盒的飛機,所以分型面應在肥皂盒中選擇擁有最大的射影平面。一模四腔腔數(shù),門在盒子的底部邊緣,使用門。根據(jù)塑料零件和模具的結(jié)構(gòu),選擇模具的兩個模板。設置通道直徑8毫米,約10毫米的距離塑料部件,頂針和插入8毫米的最小距離。移動集模具冷卻,模具冷卻水流驅(qū)動模板,在流經(jīng)核心驅(qū)動的模板,模板之間的核心和配備橡膠墊圈防止泄漏,模具部分和動態(tài)模型。柱塞直徑8毫米,每個腔有四個。底部安裝拉桿的主流方法的核心材料,直徑8毫米。頂針和拉桿和模具型腔。根據(jù)塑料零件的特點,整個嵌入式模具。考慮冷卻水通道的分布和模板的螺孔,導料銷、導套,等等,估計模具大小水平面投影,找出相似的模組的標準。這個模組的基礎上LKM門模具架、模組具體參數(shù)的確定如表模具型腔確定最經(jīng)濟的腔數(shù)基本上是塑料的生產(chǎn)成本的經(jīng)濟核算。但在初期注塑設計,澆注系統(tǒng)等技術(shù)參數(shù)是未知的,這腔是一種估計預測,建立拇指第一假設模具設計完成后,進來嗎成本會計。因此,進行綜合考慮,早期的平衡設定一模四腔腔型布局,澆注系統(tǒng)的設計,澆注系統(tǒng)指的是注塑模具從結(jié)束的開始融化之間的空腔的主流方式喂養(yǎng)頻道,澆注系統(tǒng)的設計也是一個關(guān)鍵環(huán)節(jié)在注塑模具的設計,其設計是否合理將影響塑料制品的質(zhì)量。澆注系統(tǒng)的作用是由注入死的噴嘴塑料熔體順利和成功,壓實和壓力。本設計采用平衡式布置,圓形截面分布。選擇門的形式直接澆口,由于壁厚1毫米,所以選擇的接觸部分門1毫米寬。生成的大門,流道。塑料制品和現(xiàn)代工業(yè)生產(chǎn)的在人們的日常生活中已經(jīng)越來越廣泛的應用。隨著塑料工業(yè)的發(fā)展,社會對塑料產(chǎn)品的需求變得越來越大。據(jù)統(tǒng)計,在現(xiàn)代工業(yè)生產(chǎn)中,60%到90%的工業(yè)產(chǎn)品需要使用模具,模具工業(yè)已成為工業(yè)發(fā)展的基礎[2]。塑料注塑模具重量越來越大的份額,其發(fā)展非常迅速,一個偉大的壓倒一切的趨勢在其他模具。專家預測,在未來的模具市場中,塑料模具模具總數(shù)的比例將逐漸增加,增長速度將高于其它模具??偟膩碚f,國外模具行業(yè)開始前,發(fā)展更向前,技術(shù)更加成熟,現(xiàn)在注塑技術(shù)的多站點,效率高、自動化、連續(xù)、低成本方向發(fā)展。例如:(1)混合和注射成型組合技術(shù)應用,WP將玻璃纖維雙螺桿復合聚合物注射成型技術(shù)組合活塞技術(shù)與多階段系統(tǒng)的組合與連續(xù)混合注塑過程[2]。(2)多站點、連續(xù)成型技術(shù)的應用程序。64年德國FOBOHA公司4station既注塑成型產(chǎn)品技術(shù)、結(jié)構(gòu)4的64名男性和可旋轉(zhuǎn)的中心兩邊各一套模具和注塑機器,每個模具旋轉(zhuǎn)了90度后,兩個同時注塑機器。如果兩種不同的材料或顏色的注射產(chǎn)品,每個旋轉(zhuǎn),設備可以64年注塑產(chǎn)品。意大利PRESMA 10station交聯(lián)EVA泡沫注塑機,注塑機器和一個邊緣的安排10套注塑模具組成,進而死10是搬到注塑機注塑前,注射后需要做模具的刻板印象,模具,刪除這篇文章,一個模型的過程,這些過程由計算機自動控制。交聯(lián)泡沫噴射裝置將中型塑料注塑過程連續(xù),提高注塑機的生產(chǎn)力[2]。法國十億公司雙注射,可旋轉(zhuǎn)的模具注塑技術(shù),兩位男平行放置在一個可旋轉(zhuǎn)的支撐結(jié)構(gòu),兩個注塑機器同時進入各自的不同材料的注射模具,然后打開模具,男模腳手架向前旋轉(zhuǎn)了180度后,刪除陽模上顏色產(chǎn)品,和下一個注塑工作。雙注入設備,提高水平和連續(xù)操作的空間設備緊湊。(3)應用圖片螺桿注射成型技術(shù)。INSHOT公司引入了顏色picturescrew注塑技術(shù),可以被稱為共注塑成型技術(shù)有重大突破。這個注塑設備主要由一個圓柱體,兩個picturescrew和兩套傳動組件。大腔小螺桿螺桿螺旋筒組成,這兩個螺絲旋轉(zhuǎn)與各自的移動兩個獨立的驅(qū)動系統(tǒng)是由注塑模具結(jié)構(gòu)相對簡單,大大減少了熔池模塑成型技術(shù)設備需要成本。此外,外國壓縮成型和吹塑自動化和連續(xù)生產(chǎn)技術(shù)也有很大的進步。如意大利薩克米接二連三蘇帽壓成型機,主要由1板的擠壓機,自動切片與快速旋轉(zhuǎn)機制64套帽壓縮模具組件。擠塑板切成女性模具的下落,陽模和女合模,模具原型的轉(zhuǎn)折致動器陽模帽上移除。該設備可以每分鐘最快的1200塑料帽,高生產(chǎn)效率是目前在中國很難看到[2]。相比之下,國內(nèi)塑料模具比國外落后階段,大多數(shù)當前使用的是單穴模具型腔僅僅超過70%,仍由一個復雜的多腔注塑成型多色注塑成型能夠初步設計和制造,但有很多精密模具必須依靠進口。然而,現(xiàn)在國家開始死于經(jīng)過半個世紀的發(fā)展,模具行業(yè)已經(jīng)大大發(fā)展,其中約30%的塑料,平均年增長率為13%。模具制造水平已經(jīng)大大提高,在大型模具能夠生產(chǎn)48英寸大屏幕彩電成型注塑模具、儀表板和其他塑料模具,精密塑膠模具方面,相機能產(chǎn)生塑料模具、多腔模具和小模數(shù)齒輪塑料模具。如天津、Tianjinday電氣有限公司和煙臺北極星模具有限公司,VCD和DVD制造
