【正文】 chnical and mon characteristics of the type system mold is according to the kind piece for basis, sprinkle a convex and cave mold, a surface do not need the machine to physically to mainly have following several categories type in the mold. 4 extrusions takes shape the technology Using the berylliuim copper alloy good thermal conductivity and the stability, after the solid melt aging treatment of metal, use the swaging pressure to make the mold concave model cavity. Its characteristic is makes the cycle short, the cavity precision is high (the IT7 level), surface roughness Ra= mu m, The intensity is high, the life may reach 500,000 times, does not have the environmental pollution. This technology is using the metal material in the thin crystal grain, certainly takes shape the temperature, under the low distortion speed condition, when the material has the best superplasticity, toes attend to carry out raised mold which the initiative finishes, then may extrude the concave mold with the small strength one kind of fast economical pattern making technology. Ultra models takes shape material typical representative is Zn22%AL. 5 does not have the mold multi spots forming technology Does not have the mold multi spots fast forming technology is by CAD/CAM/CAT The technology is the main method about, may adjust the base main body group highly using the puter control to form forms the surface, replaces the traditional mold to carry on the three dime nsional curved surface forming to the sheet an modern advanced manufacture technology. This technology may change the distortion way and the stressful condition at will, enhances the material the formed limit, may form repeatedly, by this elimination material interior remaining stress, the realization does not have the snapping back forming 6 triumphant Uygur bright steel belt blanking falls the material pattern making technology The new steel belt blanking falls the material pattern making technology is one kind is different with has raised, the concave mold structure steel belt mold generally, it is with specially makes the new fast economical pattern making technology by the single edge steel belt which the backing strip is posed. This kind of mold weight is 6 light, only then 200kg, the processing precision for 177?？杉庸に芰系闹饕攸c是兼?zhèn)淠静暮徒饘俚膬?yōu)良加工性能，制作工藝簡捷 (可采用模塑、澆注、拼粘、雕塑等方法 )、尺寸穩(wěn)定性好、不變形、耐潮濕、耐腐蝕、易修復(fù)、易改型、重量輕、制作周期短、成本低。 快速換模技術(shù) 由于產(chǎn)品品種的增多，使模具在生產(chǎn)中更換變得十分頻繁，于是如何縮短沖壓設(shè)備的停機時間，提高生產(chǎn)效率，快速換模技術(shù)受到了人們的關(guān)注。這種模具重量輕，一般只有 200kg，加工精度為 177。 3 澆鑄成型制模技術(shù) 澆鑄成型制模技術(shù)的共同特點是依樣件為基準，澆鑄出凸、凹模，型腔表面不需要機械加工。 2表面成型制模技術(shù) 表面成型制模技術(shù)，主要是利用噴涂、電鑄、化學腐 蝕等新的工藝方法形成型腔表面及精細花紋的一種工藝技術(shù)，實際應(yīng)用中包括以下幾種類型。 一方面企業(yè)為追求規(guī)模效益，使得模具向著高速、精密、長壽命方向發(fā)展；另一方面企業(yè)為了滿足多品種、小批量、產(chǎn)品更新?lián)Q代快、贏得市場的需要，要 求模具向著制造周期短、成本低的快速經(jīng)濟的方向發(fā)展。 1快速原型制造技術(shù) 快速原型制造技術(shù)簡稱 RPM，是 80年代后期發(fā)展起來的一種新型制造技術(shù)。 目前該技術(shù)被廣泛地用于飛機、汽車的內(nèi)飾件模具、家電、家俱、制鞋、美術(shù)工藝品等表面形狀復(fù)雜及花紋精細的各種聚氨酯制品的吹塑、吸塑、 PVC注射、 PU發(fā)泡及各類注射成型模具中。該技術(shù)是利用金屬材料在細化晶粒、一定成型溫度、低變形速率條件下，材料具有最佳超塑性時，將事先制作好的凸模，用較小的力便可擠壓出凹模的一種快速經(jīng)濟制模技術(shù)。 7模具毛坯的快速制造技術(shù) — 實型鑄造 由于大量的模具是屬于單件或小批量生產(chǎn)，模具毛坯的制造質(zhì)量和周期及成本對最終的模具質(zhì)量和周期及成本的影響是至關(guān)重要的。 沖壓單元組合技術(shù) 沖壓單元組合技術(shù)是將常規(guī)的沖模分解為一個個簡單的單元沖模，根據(jù)工序件的要求，排列組合，在同一次沖程內(nèi)完成多種沖壓工序的新型工藝裝備，工作時沖壓單元不與沖床滑塊聯(lián)接，只需滑塊打擊即可完成沖壓工作。隨著商品經(jīng)濟的發(fā)展，激烈的市場競爭，產(chǎn)品更新?lián)Q代的加速，對快速經(jīng)濟制模技術(shù)在縮短周期、降低成本，提高精度和延長壽命方面的要求勢必會越來越高。s favor and the concerned leader department39。 On the other hand enterprise in order to satisfy the multi varieties, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The puter, the laser, electronic, the new material, the new technical development, causes the fast economical pattern making technology even more 4 powerful, the application scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more rema
