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)間里(li)，造(zao)型(xing)(xing)(xing)造(zao)芯都實現了機械化或(huo)自動化。常用的砂型(xing)(xing)(xing)造(zao)型(xing)(xing)(xing)造(zao)芯設備有(you)高、中、低(di)壓造(zao)型(xing)(xing)(xing)機、拋(pao)砂機、無箱射壓造(zao)型(xing)(xing)(xing)機、射芯機、冷(leng)和(he)熱芯盒(he)機等。
叉車配重鐵(tie)(tie)工藝(yi)可(ke)分為(wei)(wei)三個(ge)基(ji)本部分，即(ji)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)準(zhun)備、鑄型(xing)(xing)準(zhun)備和(he)鑄件(jian)處理。 配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)是指配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產中用于(yu)澆注(zhu)鑄件(jian)的金(jin)(jin)屬(shu)材(cai)料，它(ta)是以一(yi)種金(jin)(jin)屬(shu)元素為(wei)(wei)主(zhu)要(yao)成分，并加入其他(ta)金(jin)(jin)屬(shu)或非金(jin)(jin)屬(shu)元素而組成的合金(jin)(jin)，習慣上(shang)稱為(wei)(wei)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合金(jin)(jin)，主(zhu)要(yao)有鑄鐵(tie)(tie)、鑄鋼和(he)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有色(se)合金(jin)(jin)。叉(cha)(cha)車(che)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造(zao)型(xing)(xing)材(cai)料的不同，又可(ke)分為(wei)(wei)兩大類：一(yi)類以天然礦(kuang)產砂(sha)石作(zuo)為(wei)(wei)主(zhu)要(yao)造(zao)型(xing)(xing)材(cai)料，如熔模配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一(yi)類以金(jin)(jin)屬(shu)作(zuo)為(wei)(wei)主(zhu)要(yao)鑄型(xing)(xing)材(cai)料，如金(jin)(jin)屬(shu)型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離(li)心配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連(lian)續(xu)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉(cha)(cha)車(che)配(pei)(pei)件(jian)鐵(tie)(tie)、低壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。
配重塊結(jie)構設(she)計除(chu)應符(fu)合機(ji)器設(she)備本身的(de)要(yao)求和機(ji)械加工(gong)工(gong)藝性的(de)要(yao)求外，還(huan)應符(fu)合鑄造工(gong)藝的(de)要(yao)求，配重(zhong)塊的(de)結(jie)構設(she)計應注意(yi)以下幾點：
一、要便于制造(zao)模型、芯盒和造(zao)型：
1)配重塊的(de)外(wai)形應力求簡(jian)單，以便于起模，應盡量使鑄(zhu)造分型面(mian)為(wei)平面(mian)，且(qie)數目(mu)小;
2)配重塊的內腔應(ying)(ying)力求(qiu)鑄造時(shi)不(bu)用(yong)或少用(yong)型芯，當(dang)采(cai)用(yong)型芯時(shi)，應(ying)(ying)方便其支撐、固定及排氣出砂，時(shi)應(ying)(ying)設有足夠的工藝孔;
3)對(dui)于(yu)配重(zhong)塊內外側面及加強肋等(deng)結(jie)構(gou)(gou)，應在起模方(fang)向設有的結(jie)構(gou)(gou)斜(xie)度;
4)配重塊上的(de)凸(tu)臺(tai)部分與配重鐵本體(ti)(ti)不(bu)應(ying)相差過大(da)，好取同(tong)一高度(du)，同(tong)一面上的(de)距離(li)較(jiao)近的(de)幾個凸(tu)臺(tai)，好連成整體(ti)(ti)的(de)凸(tu)起部分。
