Also, theseparts are the critical ponents in the mould design Their geometrical requirements may be , some tools developed to design the core and thecavity based on partial automation and partialinteraction can be quite useful. Design for assembly. In conventional CAD/CAMsystems, moulds are represented and stored as a plete geometric and topological solid model. Thismodel is posed of faces, edges and vertices in athree dimensional (3D) Euclidean space. Such a representationis suitable for visual display and performinggeometrically putationintensive taskssuch as engineering analysis and simulation. However,this form is not appropriate for tasks thatrequire decisionmaking based on highlevel informationabout product geometric entities and theirrelationships. Mould designers prefer a design forassembly environment instead of a simple solid modelenvironment. This idea is also presented in Ye et al.’s work [24]. A design for manufacture. A plete injectionmould design development cycle can be posed ofthe mould design and mould manufacturing integrate CAD/CAM into the mould design, themanufacturing features on the mould should be abstracteand analysed for the specific NC machine. Both the process plan and the NC code should beautomatically generated to enable the final designed mould to be manufactured. A design for engineering drawings. For manypanies, the injection mould design has to be represented in the form of engineering drawingswith detailed dimensions. CAD/CAM tools that are able to automatically generate these engineeringdrawings from the final injection mould design will be on the above analysis, our research focus is todevelop techniques to represent ‘what they have’ and‘what they want’.Representing ‘what they want’ is actually the representationof the knowledge and injection mould ‘what they want’ means to integrate finished piece standard the representation with intelligent and interactive tools forthe injection mould design into a pleted designenvironment. Therefore, an IKBMOULD is proposedfor mould designers to realise the above two requirements 新一代注塑技術(shù) 概述 轉(zhuǎn)位瓶胚注塑技術(shù)是在 Husky 注塑系統(tǒng)雙壓板機(jī)器設(shè)計(jì)發(fā)展起來的。該系統(tǒng)有一個(gè)四面動(dòng)壓板繞橫軸旋轉(zhuǎn)。由于瓶胚要留在模芯上 ,瓶胚在開模不需要象在傳統(tǒng)系統(tǒng)上那么硬。 在頂部、背部和底部位置 ,氣沖成型系統(tǒng)對瓶胚提供表面冷卻。目前 ,這種系統(tǒng)用最大壁厚為 4 毫米的 克瓶胚工作。 系統(tǒng)的另一個(gè)好處是需要的地板面積減少 ,以及由于沒有機(jī)械手和引出板冷卻系統(tǒng) ,系統(tǒng)的可靠性得以提高的潛力。 瓶胚留在模芯較長時(shí)間。 由于模具內(nèi)的峰值陰模與兩個(gè)不同的螺桿相符 ,并與不同的加工設(shè)置一致 ,乙醛量到底有多低主要原因在于模具集料管。這些程序通常需要將已有的模塊和制作好的模件裝配好。 組裝設(shè)計(jì) CAD/CAM 設(shè)計(jì)系統(tǒng)中形儲(chǔ) 存模型在一個(gè)三維空間以邊和面的形式生成。他們的幾何形狀要求可能相當(dāng)苛刻。 設(shè)計(jì)者從專業(yè)知識中得出模具設(shè)計(jì)的設(shè)計(jì)計(jì)劃和詳細(xì)步驟原材 料的選擇 他們所想要得一個(gè)先進(jìn)的交互式模具設(shè)計(jì)環(huán)境。 轉(zhuǎn)位系統(tǒng)用幾種不同材料及測試的兩種不同材料和兩種不同的聚對苯二甲酸乙二醇酯螺桿設(shè)計(jì) ,可以看到乙醛 (AA)量一直較低。去掉這一熱源就消除一個(gè)結(jié)晶源。制件頂出現(xiàn)在不是機(jī)械循環(huán)時(shí)間的一個(gè)因素。生產(chǎn)的轉(zhuǎn)位樣品可能平均較輕 ,因?yàn)樗鼈兊闹亓糠植家o密得多。重力幫助確保制件脫離模具落下。兩 42 個(gè)不同的聚對苯二甲酸乙二醇酯螺桿用于本系統(tǒng) ,每個(gè)都取得了可以接受的效果。s pressure time the standard not necessaries , and that traditional system goes up such as being living is stiff in that way .Hence , the machinery cycle that the overwhelming majority cooling may be living soon afterwards perioc through shuts the standard revolves up to bee cool on the rush pith at the standard .Afterwards the cycle needs an extraordinary brief cooling perioc in order to permit the pattern to eluc
