</p> <p> <p> 與粘土砂相比，樹脂砂鑄造生產(chǎn)線生產(chǎn)的鑄件外觀質(zhì)量依賴于模具的質(zhì)量，因而樹脂砂對(duì)模具的質(zhì)量要求較高。模具工藝時(shí)使其較好的適應(yīng)樹脂砂造型的需要，主要在以下幾個(gè)方面： </p> <p> 加工余量 </p> <p> 硬化后的樹脂砂鑄型有較好的剛度和較高的尺寸精度，且不易變形，所以在選擇工藝參數(shù)時(shí)，可以選取較小的機(jī)械加工余量，從而減少金屬溶液的消耗和機(jī)械加工的成本，從而可以提高鑄件的尺寸精度。 </p> 樹脂砂在起模時(shí)已具有一定的硬化強(qiáng)度，較小的退讓性，較大的摩擦力，若采用敲擊的方法起模，容易損壞模具，同時(shí)樹脂砂的可修補(bǔ)性差，起模時(shí)，若受到破壞，較難修補(bǔ)。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
