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(jian)里，造(zao)(zao)型造(zao)(zao)芯都實現了機械(xie)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(ya)(ya)造(zao)(zao)型機、拋砂機、無箱射(she)壓(ya)(ya)造(zao)(zao)型機、射(she)芯機、冷和熱芯盒(he)機等。
叉車配重鐵(tie)(tie)(tie)工藝可(ke)分為(wei)三個基本部(bu)分，即(ji)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金屬(shu)(shu)(shu)(shu)準(zhun)(zhun)備、鑄型(xing)(xing)準(zhun)(zhun)備和鑄件處理。 配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金屬(shu)(shu)(shu)(shu)是指配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)生產(chan)中用(yong)于澆注鑄件的(de)金屬(shu)(shu)(shu)(shu)材料，它是以(yi)一(yi)種(zhong)金屬(shu)(shu)(shu)(shu)元(yuan)素為(wei)主要(yao)(yao)成分，并(bing)加(jia)入其他(ta)金屬(shu)(shu)(shu)(shu)或(huo)非金屬(shu)(shu)(shu)(shu)元(yuan)素而組成的(de)合金，習慣上稱為(wei)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)合金，主要(yao)(yao)有(you)鑄鐵(tie)(tie)(tie)、鑄鋼和配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)有(you)色合金。叉車(che)(che)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)按造型(xing)(xing)材料的(de)不同，又可(ke)分為(wei)兩大類(lei)：一(yi)類(lei)以(yi)天然(ran)礦產(chan)砂石作為(wei)主要(yao)(yao)造型(xing)(xing)材料，如熔(rong)模配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、殼型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、負壓(ya)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、泥型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、實型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、陶瓷(ci)型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等(deng);一(yi)類(lei)以(yi)金屬(shu)(shu)(shu)(shu)作為(wei)主要(yao)(yao)鑄型(xing)(xing)材料，如金屬(shu)(shu)(shu)(shu)型(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、離心配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、連續配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、叉車(che)(che)配(pei)件鐵(tie)(tie)(tie)、低(di)壓(ya)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等(deng)。
配重塊結構設(she)(she)計除應符合機器設(she)(she)備本身的(de)要求和機械加工(gong)工(gong)藝(yi)性的(de)要求外，還應符合鑄造(zao)工(gong)藝(yi)的(de)要求，配重塊的(de)結構設(she)(she)計應注(zhu)意以(yi)下幾點：
一(yi)、要便于制造(zao)模型(xing)、芯(xin)盒和造(zao)型(xing)：
1)配(pei)重(zhong)塊的外形應(ying)力(li)求簡單，以便(bian)于(yu)起模，應(ying)盡量使鑄造分型面為平面，且(qie)數目小;
2)配(pei)重塊的內腔(qiang)應(ying)力求鑄造(zao)時(shi)不(bu)用(yong)或少用(yong)型芯，當采用(yong)型芯時(shi)，應(ying)方便其支撐、固定及(ji)排氣(qi)出砂，時(shi)應(ying)設(she)有足夠的工藝孔(kong);
3)對于配(pei)重(zhong)塊內外側面及加強肋等(deng)結構，應在起(qi)模方向設有的(de)結構斜(xie)度;
4)配重塊上的(de)凸臺(tai)部分(fen)與配重鐵本體不應相差過大，好取(qu)同一高度，同一面(mian)上的(de)距離較近的(de)幾(ji)個凸臺(tai)，好連成整體的(de)凸起(qi)部分(fen)。
