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。負(fù)壓澆注，有利于金屬的補(bǔ)給，鑄件冒口可減小，鑄件表面光潔，尺寸精度高，加工余量減少。</p><div

style="text-indent:25px">V法鑄造是真空密封造型或負(fù)壓造型鑄造工藝的簡(jiǎn)稱，其原理是利用塑料薄膜覆模造型并密封砂箱，依靠真空泵抽出型內(nèi)空氣，造成型內(nèi)箱外壓力差，使干砂緊實(shí)，形成所需型腔。其比較大優(yōu)勢(shì)是型砂不使用粘結(jié)劑，干砂回用率高達(dá)95%以上，不僅節(jié)能環(huán)保、落砂簡(jiǎn)便、改善勞動(dòng)條件，而且鑄件表面品質(zhì)和尺寸精度**提高。V法鑄造是日本長(zhǎng)野縣工業(yè)試驗(yàn)所和秋田株式會(huì)社于1971年的發(fā)明專利。V法鑄造至今經(jīng)過(guò)了38年的發(fā)展，同消失模鑄造一樣，作為第3代造型方法即物理硬化方法，在世界上尤其是在中國(guó)獲得了長(zhǎng)足的發(fā)展。2008年時(shí)我國(guó)鑄鐵件廠產(chǎn)量達(dá)2510萬(wàn)噸，其中按短流程工藝生產(chǎn)的鑄件約占11.3%。南京質(zhì)量V法鑄造介紹</p><p

砂芯的設(shè)計(jì)主要是排氣問(wèn)題，在砂芯的分芯面上開(kāi)挖排氣和集氣通道，在這些通道上扎制砂芯內(nèi)部排氣孔，再將這些排氣和集氣通道進(jìn)行匯集，通過(guò)匯集點(diǎn)向鑄型外排出，使得砂芯內(nèi)氣體有效排出型外，避免氣孔和鑄件內(nèi)壁氧化等缺點(diǎn)。 </p> <p> <br /> </p> <p> <br /> </p> <p> 5.澆注速度、真空保持時(shí)間的設(shè)計(jì) </p> <p> 由于V法鑄造的真空特點(diǎn)，澆注過(guò)程中，外型和坭芯均處于真空狀態(tài)，其澆注充型的能力遠(yuǎn)大于其它鑄造工藝。鑒于V法鑄造冷卻緩慢和真空特性，澆注溫度不宜偏高，目的是為了避免或減弱收縮類缺點(diǎn)。 </p> <p> 在通氣和排氣系統(tǒng)適當(dāng)?shù)那闆r下，在澆注末期透氣孔不出現(xiàn)“嗆火”狀態(tài)下可以提高澆注速度，滿足產(chǎn)品質(zhì)量前提下，可以在平常澆注速度的基礎(chǔ)上提高20%～30%;澆注終了的點(diǎn)澆等與其它工藝相同。南京質(zhì)量V法鑄造介紹</p><p
