　　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)(zao)型造(zao)(zao)(zao)芯都(dou)實現了(le)機(ji)(ji)械(xie)化或自動化。常用的砂(sha)型造(zao)(zao)(zao)型造(zao)(zao)(zao)芯設備(bei)有高(gao)、中(zhong)、低(di)壓造(zao)(zao)(zao)型機(ji)(ji)、拋砂(sha)機(ji)(ji)、無箱(xiang)射(she)壓造(zao)(zao)(zao)型機(ji)(ji)、射(she)芯機(ji)(ji)、冷和熱芯盒(he)機(ji)(ji)等。

　　叉車配重鐵(tie)(tie)(tie)工(gong)藝(yi)可(ke)分(fen)為(wei)(wei)(wei)三個基本部分(fen)，即配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金(jin)屬(shu)(shu)準(zhun)備、鑄(zhu)(zhu)(zhu)(zhu)型(xing)(xing)(xing)(xing)準(zhun)備和鑄(zhu)(zhu)(zhu)(zhu)件處(chu)理。配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金(jin)屬(shu)(shu)是指配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)生產中用于(yu)澆注鑄(zhu)(zhu)(zhu)(zhu)件的金(jin)屬(shu)(shu)材料(liao)，它是以(yi)一(yi)種金(jin)屬(shu)(shu)元(yuan)素為(wei)(wei)(wei)主(zhu)(zhu)要成分(fen)，并(bing)加(jia)入其他金(jin)屬(shu)(shu)或非金(jin)屬(shu)(shu)元(yuan)素而(er)組(zu)成的合(he)金(jin)，習(xi)慣(guan)上稱為(wei)(wei)(wei)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)合(he)金(jin)，主(zhu)(zhu)要有鑄(zhu)(zhu)(zhu)(zhu)鐵(tie)(tie)(tie)、鑄(zhu)(zhu)(zhu)(zhu)鋼和配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)有色(se)合(he)金(jin)。叉車(che)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)按(an)造(zao)型(xing)(xing)(xing)(xing)材料(liao)的不同，又(you)可(ke)分(fen)為(wei)(wei)(wei)兩大類(lei)(lei)：一(yi)類(lei)(lei)以(yi)天然礦產砂石作為(wei)(wei)(wei)主(zhu)(zhu)要造(zao)型(xing)(xing)(xing)(xing)材料(liao)，如(ru)熔模配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、殼型(xing)(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、負壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、泥型(xing)(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、實型(xing)(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、陶瓷型(xing)(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等;一(yi)類(lei)(lei)以(yi)金(jin)屬(shu)(shu)作為(wei)(wei)(wei)主(zhu)(zhu)要鑄(zhu)(zhu)(zhu)(zhu)型(xing)(xing)(xing)(xing)材料(liao)，如(ru)金(jin)屬(shu)(shu)型(xing)(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、離心(xin)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、連續配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、叉車(che)配(pei)(pei)件鐵(tie)(tie)(tie)、低(di)壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等。

　　配重塊結(jie)構設計除(chu)應符合(he)機(ji)器設備本身的要求和機(ji)械加(jia)工工藝性(xing)的要求外，還應符合(he)鑄造工藝的要求，配重塊的結(jie)構設計應注意(yi)以下(xia)幾點：

　　一、要便于制造(zao)模型、芯盒(he)和造(zao)型：

　　1)配重塊的(de)外形應力(li)求簡單，以(yi)便于起模(mo)，應盡量(liang)使鑄造分型面(mian)為平面(mian)，且數目小;

　　2)配(pei)重塊的內腔應(ying)力求鑄(zhu)造時(shi)(shi)(shi)不用或少用型芯，當采用型芯時(shi)(shi)(shi)，應(ying)方便其支撐、固定及排氣(qi)出砂，時(shi)(shi)(shi)應(ying)設(she)有足夠的工藝孔;

　　3)對于配重塊內外側面及加強肋(lei)等結構(gou)(gou)，應在起模(mo)方向(xiang)設有的(de)結構(gou)(gou)斜度;

　　4)配重(zhong)塊上的凸臺部(bu)分與配重(zhong)鐵本體不(bu)應相差過大，好取同一高度，同一面上的距離較(jiao)近(jin)的幾(ji)個凸臺，好連(lian)成(cheng)整體的凸起部(bu)分。
