　　鑄件的精度和生產過程的經濟表現，主要取決于這道工序。在很多現代化的配重鐵車間里，造(zao)(zao)型造(zao)(zao)芯都實現了機(ji)(ji)(ji)械化或自動(dong)化。常用的砂型造(zao)(zao)型造(zao)(zao)芯設備有高、中(zhong)、低壓造(zao)(zao)型機(ji)(ji)(ji)、拋(pao)砂機(ji)(ji)(ji)、無箱射壓造(zao)(zao)型機(ji)(ji)(ji)、射芯機(ji)(ji)(ji)、冷(leng)和熱芯盒(he)機(ji)(ji)(ji)等。

　　叉車配重鐵(tie)(tie)工藝可(ke)分(fen)為(wei)三個基本部分(fen)，即(ji)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)準(zhun)備、鑄(zhu)(zhu)型準(zhun)備和鑄(zhu)(zhu)件處理(li)。配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)是(shi)指配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生(sheng)產(chan)中(zhong)用(yong)于澆(jiao)注鑄(zhu)(zhu)件的金(jin)(jin)屬(shu)(shu)材料(liao)(liao)，它(ta)是(shi)以一種金(jin)(jin)屬(shu)(shu)元(yuan)素(su)為(wei)主要(yao)成(cheng)分(fen)，并加(jia)入其他金(jin)(jin)屬(shu)(shu)或非金(jin)(jin)屬(shu)(shu)元(yuan)素(su)而組成(cheng)的合(he)(he)金(jin)(jin)，習慣(guan)上稱為(wei)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合(he)(he)金(jin)(jin)，主要(yao)有(you)鑄(zhu)(zhu)鐵(tie)(tie)、鑄(zhu)(zhu)鋼(gang)和配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有(you)色合(he)(he)金(jin)(jin)。叉車配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造型材料(liao)(liao)的不同，又可(ke)分(fen)為(wei)兩大類(lei)(lei)：一類(lei)(lei)以天然礦產(chan)砂石作(zuo)為(wei)主要(yao)造型材料(liao)(liao)，如熔模配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一類(lei)(lei)以金(jin)(jin)屬(shu)(shu)作(zuo)為(wei)主要(yao)鑄(zhu)(zhu)型材料(liao)(liao)，如金(jin)(jin)屬(shu)(shu)型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車配(pei)(pei)件鐵(tie)(tie)、低壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。

　　配重塊結構(gou)設計除應符合機(ji)器設備本身的(de)要求(qiu)和機(ji)械加(jia)工(gong)工(gong)藝性的(de)要求(qiu)外，還應符合鑄(zhu)造(zao)工(gong)藝的(de)要求(qiu)，配重塊的(de)結構(gou)設計應注意以下幾點：

　　一、要便于制造模(mo)型(xing)、芯盒和造型(xing)：

　　1)配重塊的外形應力(li)求簡單，以便于起模，應盡量使(shi)鑄造分型面為平面，且(qie)數目小;

　　2)配(pei)重(zhong)塊的(de)內腔(qiang)應(ying)力求鑄(zhu)造時不用(yong)或少用(yong)型芯，當采用(yong)型芯時，應(ying)方便其支撐、固(gu)定(ding)及排氣出砂，時應(ying)設有(you)足夠的(de)工藝孔(kong);

　　3)對于配(pei)重塊內外側面及加強肋等結構，應在起模方向(xiang)設(she)有(you)的(de)結構斜度;

　　4)配重(zhong)塊上的(de)凸(tu)臺部(bu)分(fen)與(yu)配重(zhong)鐵本體不(bu)應相差過大，好(hao)取同一高度(du)，同一面(mian)上的(de)距(ju)離較近的(de)幾個(ge)凸(tu)臺，好(hao)連成整(zheng)體的(de)凸(tu)起部(bu)分(fen)。
