【正文】 Interbased intelligent injection mould design system is proposed as shown in Fig. 2 . It consists of a knowledgebased mould design system embedded in an Interbased environment. Mould design generally involves plex and multirelated design problems and thus lacks a plete quantitative and structured approach. The present methodology has involved breaking down the plete design problem into a number of subproblems (functional designs , . feed system, cooling system, etc. ) and developing a knowledge base of solutions for the various subproblems. All design activities are organized in seven functional modules , namely , cavity layout design, feed design, cooling design, ejection — 11 — design, mould construction, mould base selection and standard ponents selection. These modules are used to generate the functional designs including cavity layout , feed design, cooling circuit, ejection devices , mould construction and to select the standard mould base and ancillary ponents including register rings, guide bushes, guide pillars, fasteners , etc. The development of a prototype Interbased intelligent system for injection mould design has been described in this paper. The architecture of the system consists of an interactive KB mould design system embedded in an Inter environment. A Javaenabled solution together with artificial intelligence techniques is employed to develop such a worked interactive CAD system. Mould design generally involves plex and multirelated design problems and thus lacks a plete quantitative and structured approach. The present methodology has involved breaking down the plete design problem into a number of sub problems (functional designs, . Feed system, cooling system, etc.) and developing a knowledge base of solutions for the various subproblems. By using a coding system as the mechanism of inference engine, the knowledge base is accessed from independent interactive program , which aids the designer to select a number of remended solutions to the particular functional design under consideration. The selection of the actual solutions and their final development into a finished design is left to the mould designer so that their own intelligence and experience could also be incorporated with the total mould design. In the implementation of the methodology, the program was written in modular structure to facilitate access to the knowledge base and to ensure its further development and extension. The approach adopted both speeds up the design process and facilitates design standardization which in turn increases the speed of mould manufacture. The system can be incorporated as one of the modules of a collaborative product development system to provide an effective and feasible tool to aid the collaborative design and development works of injection moulds in the small and medium sized industries to satisfy the stringent — 12 — requirements of nowadays petitive global market . 。 the algorithms to automate mould generation 。模具設(shè)計(jì)通常涉及復(fù)雜 、 多元相關(guān) 的 設(shè)計(jì)問(wèn)題 并且 缺乏一個(gè)完整定量 而且 結(jié)構(gòu)化 的 方法。這些模塊用于生成功能設(shè)計(jì)包括型腔布局設(shè)計(jì) 、進(jìn)料設(shè)計(jì)、 冷卻回路 、注射 裝置 、模具結(jié)構(gòu)和選擇標(biāo)準(zhǔn)模架及配套元件包括 : 登記環(huán) 、 導(dǎo)套 、 導(dǎo)柱 、扣 件等。它 的組成是將 基于知識(shí)的模具設(shè)計(jì)系統(tǒng)嵌入一個(gè)基于互聯(lián)網(wǎng)的環(huán)境。 基于網(wǎng)絡(luò)的模具設(shè)計(jì)系統(tǒng)利用互聯(lián)網(wǎng)技術(shù)和基于知識(shí)的方法可以提供一個(gè)有效可行的工具,幫助小型和中型企業(yè) 中 注塑模具 的協(xié)同開(kāi)發(fā),從而滿足當(dāng)今 全球市場(chǎng)競(jìng)爭(zhēng) 中的嚴(yán)格要求 。 前者包括計(jì)算機(jī)輔助繪圖和圖形 、 數(shù)據(jù)減少和轉(zhuǎn)變;而后者涉及數(shù) 字 建模與分析。 KB 系統(tǒng)已表現(xiàn)出極大的潛力,協(xié)助設(shè)計(jì)師與 用于 概念 化 設(shè)計(jì) 的 計(jì)算機(jī) 設(shè)計(jì) 系統(tǒng) 相互作用,并且 采用具有廣泛分析手段 的 工程法則 幫助完成 最終工程模具設(shè)計(jì)。然而,這些限制了特殊區(qū)域或簡(jiǎn)單部分的設(shè)計(jì),而且不夠成熟,但對(duì)于一般的模具設(shè)計(jì)則足夠?qū)嵱昧恕? 近年來(lái),研究人員已經(jīng)開(kāi)始采用基于知識(shí)的方法來(lái)解決注塑成型及模具設(shè)計(jì)問(wèn)題。馬等人運(yùn)用面對(duì)對(duì)象的方法對(duì)塑料注射模具設(shè)計(jì)的標(biāo)準(zhǔn)組件庫(kù)的發(fā)展進(jìn)行了描述。陳等人提出了一種對(duì)于德克賽爾模具和難于決策的脫 — 4 — 模方向的測(cè)定方法。 惠和譚提出了基于掃描操作的啟發(fā)式操作方法用來(lái)開(kāi)發(fā)用于確定脫模方向,分型線,側(cè)型芯等的自動(dòng)化模具設(shè)計(jì)系統(tǒng)。復(fù)雜的塑料零件,其它一些機(jī)制如幻燈片,旋轉(zhuǎn)裝置等等,也可能參與模具整體結(jié)構(gòu)。當(dāng)制品在模腔中凝固并冷卻 下來(lái)之后,我們通過(guò)注噴射系統(tǒng)將其從模腔中頂出。 模具設(shè)計(jì)的項(xiàng)目通常首先要考慮經(jīng)濟(jì)方面,即為了滿足交貨日期和其他要求,我們要考慮有多少配件可以并且應(yīng)該采用一模一腔的模式生產(chǎn)的問(wèn)題。 本文的其余部分組織如下 : 2 部分簡(jiǎn)要介紹了注射模具設(shè)計(jì) ; 3 部分介紹了前人 在 模具設(shè)計(jì)及相關(guān)領(lǐng)域的研究成果 ; 基于互聯(lián)網(wǎng)的模具設(shè)計(jì)系統(tǒng) 的結(jié)構(gòu)安排在第 4 節(jié) ; 5 部分是結(jié)論。當(dāng)前網(wǎng)絡(luò)的發(fā)展和信息技術(shù)可以提供一個(gè)解決方案, 來(lái) 支持和 共同 促進(jìn)在不同地理上分布企業(yè) 的 產(chǎn)品開(kāi)發(fā)。因此 ,智能 CAD 工具 可以 協(xié)助模具設(shè)計(jì)過(guò)程中的 各項(xiàng)任務(wù) ,對(duì)于提高模具制造工業(yè)的生產(chǎn)效率非常重要。注塑模具設(shè)計(jì)包括廣泛的 關(guān)于模具元件結(jié)構(gòu)和功能的 經(jīng)驗(yàn)知識(shí) (啟發(fā)式知識(shí) )。 然而, 由于全球化的市場(chǎng) ,短生命周期產(chǎn)品的開(kāi)發(fā) ,增加產(chǎn)品多樣化、高要求的產(chǎn)品質(zhì)量 ,當(dāng)前塑料工業(yè) 正處在巨 大的 壓力 下。該方法加快了設(shè)計(jì)進(jìn)程,也促進(jìn)了設(shè)計(jì)的標(biāo)準(zhǔn)化,從而加快了模具制造的的速度。該系統(tǒng)的架構(gòu)包括一個(gè)嵌入網(wǎng)絡(luò)環(huán)境的交互式 KB 模具設(shè)計(jì)系統(tǒng)。 理工學(xué)院 畢業(yè)設(shè)計(jì) (論文 )外文資料翻譯 專(zhuān) 業(yè): 高分子材料與工程 姓 名: 范雅軒
