　　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(che)間(jian)里，造(zao)型(xing)(xing)造(zao)芯(xin)都(dou)實現了(le)機(ji)械化或(huo)自動化。常用(yong)的砂型(xing)(xing)造(zao)型(xing)(xing)造(zao)芯(xin)設備有(you)高、中、低壓(ya)造(zao)型(xing)(xing)機(ji)、拋砂機(ji)、無箱射壓(ya)造(zao)型(xing)(xing)機(ji)、射芯(xin)機(ji)、冷和熱芯(xin)盒機(ji)等。

　　叉車配重鐵(tie)(tie)工藝可(ke)分(fen)為(wei)三(san)個基本部(bu)分(fen)，即配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)準(zhun)備(bei)、鑄(zhu)(zhu)(zhu)型(xing)(xing)(xing)準(zhun)備(bei)和(he)鑄(zhu)(zhu)(zhu)件處理。配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)是指配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產中(zhong)用(yong)于澆注鑄(zhu)(zhu)(zhu)件的(de)金(jin)(jin)屬(shu)(shu)材(cai)料(liao)，它是以(yi)一種金(jin)(jin)屬(shu)(shu)元素為(wei)主(zhu)(zhu)要(yao)(yao)成分(fen)，并(bing)加入其他(ta)金(jin)(jin)屬(shu)(shu)或(huo)非金(jin)(jin)屬(shu)(shu)元素而組(zu)成的(de)合金(jin)(jin)，習(xi)慣上稱(cheng)為(wei)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合金(jin)(jin)，主(zhu)(zhu)要(yao)(yao)有鑄(zhu)(zhu)(zhu)鐵(tie)(tie)、鑄(zhu)(zhu)(zhu)鋼和(he)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有色(se)合金(jin)(jin)。叉車配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造(zao)型(xing)(xing)(xing)材(cai)料(liao)的(de)不(bu)同(tong)，又可(ke)分(fen)為(wei)兩大類：一類以(yi)天然(ran)礦產砂石作(zuo)為(wei)主(zhu)(zhu)要(yao)(yao)造(zao)型(xing)(xing)(xing)材(cai)料(liao)，如熔(rong)模(mo)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負(fu)壓配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一類以(yi)金(jin)(jin)屬(shu)(shu)作(zuo)為(wei)主(zhu)(zhu)要(yao)(yao)鑄(zhu)(zhu)(zhu)型(xing)(xing)(xing)材(cai)料(liao)，如金(jin)(jin)屬(shu)(shu)型(xing)(xing)(xing)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心(xin)配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車配(pei)(pei)(pei)件鐵(tie)(tie)、低壓配(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。

　　配重塊結(jie)構設(she)計除應符合(he)機器設(she)備本(ben)身的要(yao)(yao)(yao)求(qiu)(qiu)和機械加(jia)工(gong)(gong)工(gong)(gong)藝性的要(yao)(yao)(yao)求(qiu)(qiu)外，還應符合(he)鑄(zhu)造工(gong)(gong)藝的要(yao)(yao)(yao)求(qiu)(qiu)，配重塊的結(jie)構設(she)計應注意以下幾點：

　　一、要便(bian)于制造模型(xing)(xing)、芯盒(he)和造型(xing)(xing)：

　　1)配(pei)重塊的(de)外形應力求(qiu)簡單，以便于起模(mo)，應盡(jin)量使(shi)鑄造分型面(mian)為平(ping)面(mian)，且數目(mu)小;

　　2)配(pei)重塊的內腔應(ying)力求鑄造時(shi)不用(yong)或少用(yong)型(xing)芯(xin)，當采用(yong)型(xing)芯(xin)時(shi)，應(ying)方便其支撐、固定及排氣出砂，時(shi)應(ying)設(she)有足夠的工藝孔(kong);

　　3)對于配重塊內外側(ce)面(mian)及加強肋等結構(gou)，應在起模方向設有的結構(gou)斜度(du);

　　4)配重(zhong)塊上的(de)(de)凸(tu)臺(tai)部(bu)分與配重(zhong)鐵本體不應相差(cha)過(guo)大，好取同一高度，同一面上的(de)(de)距離較近的(de)(de)幾(ji)個凸(tu)臺(tai)，好連(lian)成(cheng)整體的(de)(de)凸(tu)起(qi)部(bu)分。
