style="text-indent:25px">樹脂砂鑄件是總稱，在造型、制芯前砂粒表面上已覆有一層固態(tài)樹脂膜的型砂、芯砂稱為覆膜砂，也稱殼型(芯)砂。它**早是一種熱固性樹脂砂，由德國克羅寧(CRONING)博士于1944年創(chuàng)造。樹脂砂鑄件就是把原砂和樹脂混合后構(gòu)成樹脂砂，把樹脂砂打入模具型腔中，經(jīng)過加熱或催化劑辦法使其成型，成型后的坭芯再放入澆鑄模具中進行澆鑄。樹脂砂鑄件具有表面粗糙度小，標準精度高，質(zhì)量好的特征。對模具要求與粘土砂比較，樹脂砂鑄件的外觀質(zhì)量依賴于模具的質(zhì)量，因而樹脂砂對模具的質(zhì)量要求較高。模具工藝時使其較好的習慣樹脂砂造型的需求，主要在以下幾個方面：　　加工余量：硬化后的樹脂砂鑄型有較好的剛度和較高的標準精度，且不易變形，所以在選擇工藝參數(shù)時，能夠選取較小的機械加工余量，然后削減金屬溶液的消耗和機械加工的本錢，然后能夠前進鑄件的標準精度。北京樹脂砂模具公司</p><div

style="text-indent:25px">樹脂砂閥體以粘土和適量的水為型砂的主要粘結(jié)劑，制成砂型后直接在濕態(tài)下合型和澆注。樹脂砂閥體運用濕型鑄造。濕型鑄造歷史悠久，運用較廣。濕型砂的強度取決于粘土和水按必定份額混合而成的粘土漿。型砂一經(jīng)混好即具有必定的強度，經(jīng)舂實制成砂型后，即可滿意合型和澆注的要求。因而型砂中的粘土量和水分是十分重要的工藝因素。樹脂砂閥體以型砂和芯砂為造型資料制成鑄型，液態(tài)金屬在重力下充填鑄型來出產(chǎn)鑄件的鑄造辦法。鋼、鐵和大多數(shù)有色合金鑄件都可用砂型鑄造辦法取得。由于樹脂砂模具鑄造所用的造型資料價廉易得，鑄型制作簡潔，對鑄件的單件出產(chǎn)、成批出產(chǎn)和大量出產(chǎn)均能適應(yīng)，長期以來，一直是鑄造出產(chǎn)中的根本工藝。 </p><p> 1、樹脂砂再生線對模具的使用要求 </p> <p> <br /> </p> <p> 樹脂砂再生就是把原砂和樹脂、固化劑混合均勻后放入沙箱、容貌中造型制芯,合箱后進行澆鑄，是現(xiàn)在廣（guang）泛采用的一種鑄造方式。與粘土砂相比，樹脂砂鑄件的外觀質(zhì)量依賴于模具的質(zhì)量，因此樹脂砂對模具的質(zhì)量要求較高。 </p> <p> 2、樹脂砂再生拔模斜度：樹脂砂在起模時已具有一定的硬化強度，較小的退讓性，較大的摩擦力，若采用敲擊的辦法起模，簡單損壞模具，一起樹脂砂的可修補性差，起模時，若受到破壞，較難修補。采用樹脂砂造型時，應(yīng)根據(jù)出產(chǎn)實踐和產(chǎn)品結(jié)構(gòu)加大模具的拔模斜度，能順利的起模，得到質(zhì)量較好的鑄型。 </p> <p> <br /> </p> <p>
