V法鑄造用塑料薄膜厚為0.03～0.25mm。覆膜成型是將塑料薄膜加熱軟化，利用真空將薄膜吸附在凹凸不平的模樣表面上（如圖3.2所示）。由于模樣輪廓結(jié)構(gòu)復(fù)雜多樣，要求塑料薄膜具有較好的延伸性，不易產(chǎn)生折痕和破裂。塑料簿膜在模樣或芯盒內(nèi)的成型能力直接影響鑄件的表面光潔度和尺寸精度，因而V法鑄造的薄膜須具有以下要求： </p> <p> 好的延伸性，不得有氣泡滴和***等缺點(diǎn)；<span style="font-size:12px;">成型時形狀缺點(diǎn)不應(yīng)擴(kuò)展；</span><span style="font-size:12px;">覆膜成型后失去彈性；</span><span style="font-size:12px;">不允許與模樣材料粘??；</span><span

</p><p>?V法鑄造的特點(diǎn)<br></p><p>V法鑄造因其獨(dú)特生產(chǎn)工藝，使得生產(chǎn)出來的鑄件表面光潔度和尺寸精度高，生產(chǎn)工序簡單，金屬利用率高，模具和砂箱壽命長，減少型芯數(shù)量使用，舊砂可基本回用，節(jié)約造型成本，少污染且勞動強(qiáng)度低，適用于鑄鐵﹑鑄鋼﹑非鐵合金等鑄件的單件小批量或機(jī)械自動化大批量得生產(chǎn)。然造型操作較復(fù)雜，從造型開始至終需抽真空，且受薄膜本質(zhì)的限制，須有樹脂砂型芯方能生產(chǎn)復(fù)雜鑄件V法鑄造所用的模樣（如圖3.1所示）在V法鑄造生產(chǎn)中占有非常重要的地位，其質(zhì)量的優(yōu)劣直接影響鑄件的質(zhì)量。目前V法鑄造所用模樣一般用木質(zhì)。V法鑄造要求模樣表面光潔﹑尺寸精度高，其工藝收縮率及拔模斜度要小于粘土砂、水玻璃砂、樹脂砂等其他鑄造工藝，一般取收縮率為0．2％～0．8％，拔模斜度在0～1°。V法造型的模樣不與型砂接觸(由薄膜和涂料隔開)，磨損和變形很小，使用壽命長，但模樣結(jié)構(gòu)設(shè)計(jì)要考慮V法的要求。?<br>真空密封造型緊實(shí)原理是利用塑料薄膜密封砂箱，依靠真空抽出型內(nèi)的空氣造成鑄型內(nèi)外壓力差使干砂緊實(shí)。</p><div

通過工藝試驗(yàn)過程的開展，理解耐磨鑄件V法鑄造工藝路線，熟知工藝控制要點(diǎn)及比較好工藝參數(shù)，對于V法鑄造項(xiàng)目的順利開展具有重要意義。V法鑄造在國內(nèi)推廣早期，上述環(huán)節(jié)的缺失為不少企業(yè)釀成了重大損失，目前逐漸引起越來越多企業(yè)的重視。尤其是真空的使用和控制是V法鑄造工藝有別于傳統(tǒng)砂型鑄造的重要特征，深刻的影響著產(chǎn)品質(zhì)量和生產(chǎn)管理過程的控制等。從國外耐磨企業(yè)案例不難看出，在其探索過程中，同樣經(jīng)過了足夠的產(chǎn)品生產(chǎn)試驗(yàn)，從單件到小批量，從簡易工藝設(shè)備到大型生產(chǎn)線，在充分分析工藝過程的基礎(chǔ)上，對相應(yīng)V法工藝裝備及生產(chǎn)線有了更充分的認(rèn)識和風(fēng)險預(yù)判，為后續(xù)的批量化生產(chǎn)奠定了基礎(chǔ)。正確選擇真空泵以及合理的真空系統(tǒng)是保證V法鑄型穩(wěn)定負(fù)壓度的前提。泰州先進(jìn)V法鑄造原理</p><p
