2生產(chǎn)管理方面 </p> <p> V法鑄造工藝的成本更低，單位鑄件重量能耗和輔材消耗低，南通負(fù)壓V法鑄造企業(yè)，勞動(dòng)強(qiáng)度低；采用干砂造型無(wú)需混砂等過(guò)程，南通負(fù)壓V法鑄造企業(yè)，設(shè)備投資少，南通負(fù)壓V法鑄造企業(yè)，砂處理簡(jiǎn)單，舊砂回用率較高，不存在廢砂廢水等污染情況；模具磨損小，壽命高；高自動(dòng)化程度生產(chǎn)線生產(chǎn)效率高，人均產(chǎn)量高；但澆注時(shí)負(fù)壓度的變化大，澆注瞬間，負(fù)壓度下降快，澆注完畢后鑄型能恢復(fù)并保持較高的負(fù)壓度。南通負(fù)壓V法鑄造企業(yè)</p><div

國(guó)內(nèi)生產(chǎn)大型V法造型線的公司，其中有江陰華天科技開(kāi)發(fā)有限公司。該公司研制成功國(guó)內(nèi)首條自主創(chuàng)新、擁有自主知識(shí)產(chǎn)權(quán)的大型V法造型線，標(biāo)志著V法鑄造生產(chǎn)線依賴進(jìn)口的歷史結(jié)束。 </p> <p> 法鑄造**模具企業(yè)采用CAD/CAM技術(shù) </p> <p> 干燥良好的無(wú)缺點(diǎn)木材是V法鑄造常用模具材料。金屬材料價(jià)格昂貴，而且鉆孔較困難，并不太適合用于V法模具。另外暴露于薄膜加熱器下的金屬模具受重復(fù)加熱作用，溫度上升后易粘薄膜。因此V法鑄造企業(yè)長(zhǎng)期采用木質(zhì)材料制模，而其大多是靠模型工放樣半機(jī)械化制作。其尺寸精度較差和生產(chǎn)周期較長(zhǎng)一直是V法鑄造的瓶頸。南京真空V法鑄造效果V法鑄造中多采用干式真空泵和水環(huán)真空泵，我國(guó)主要采用水環(huán)式真空泵。</p><div

烤膜覆膜作為V法鑄造的第一步，直接影響著整個(gè)造型的質(zhì)量和效率。EVA薄膜只有在加熱烘烤到一定程度的時(shí)候，其延伸性也就是通常所說(shuō)的覆膜成形性能才能達(dá)到比較好狀態(tài)。然而，從烘烤結(jié)束到薄膜下降至模具的過(guò)程中，EVA薄膜由于逐漸遠(yuǎn)離熱源，會(huì)很快冷卻，脫離比較好覆膜狀態(tài)。這就要求覆膜架在極短的時(shí)間內(nèi)，完成覆膜動(dòng)作。大量的工藝實(shí)踐表明，覆膜架在5s內(nèi)下行到位是**為合適的，時(shí)間越長(zhǎng)，對(duì)薄膜原有的熱態(tài)延伸性削減越大。一個(gè)簡(jiǎn)單的公式：t=s/v；（t—覆膜框行走時(shí)間；s—覆膜框行程，即EVA薄膜加熱位置與模具臺(tái)面的距離；v—覆膜框下降的平均速度）顯然，覆膜框行程和下降的速度直接影響著行走時(shí)間，也就影響著覆膜成形的質(zhì)量。 </p><p style="text-indent:25px">可借鑒的參考數(shù)據(jù)是，振幅0.5mm左右，頻率不低于1500/min可以達(dá)到比較好的震實(shí)效果。不太理想的是，部分震實(shí)臺(tái)的設(shè)計(jì)參數(shù)并不滿足推薦的經(jīng)驗(yàn)數(shù)據(jù)。而鑄造企業(yè)在使用的過(guò)程中則常常發(fā)現(xiàn)，震實(shí)臺(tái)激振力不夠或過(guò)強(qiáng)，振幅不足或過(guò)大等一系列問(wèn)題。這就是為什么同樣的鑄件，同樣的砂箱，同樣的模具，在不同的廠家，震實(shí)時(shí)間，震實(shí)效果有差異的原因。更有甚者，震實(shí)臺(tái)振動(dòng)電機(jī)缺乏基本的變頻功能；哪怕具備變頻特性，也不根據(jù)震實(shí)臺(tái)負(fù)載的變化合理調(diào)整頻率，激振力等參數(shù)，以至于震實(shí)臺(tái)發(fā)揮不了應(yīng)有的作用。近年來(lái)，V法鑄造持續(xù)升溫。</p><div
