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)型造(zao)芯(xin)(xin)(xin)都(dou)實(shi)現了(le)機械化或(huo)自動化。常用的砂(sha)型造(zao)型造(zao)芯(xin)(xin)(xin)設備(bei)有高、中、低壓造(zao)型機、拋砂(sha)機、無箱(xiang)射壓造(zao)型機、射芯(xin)(xin)(xin)機、冷和熱芯(xin)(xin)(xin)盒機等。

　　叉車配重鐵(tie)(tie)工藝可分(fen)(fen)為(wei)三個(ge)基本(ben)部分(fen)(fen)，即(ji)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)(jin)屬(shu)(shu)準備、鑄型(xing)(xing)(xing)準備和(he)鑄件(jian)處(chu)理。 配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)(jin)屬(shu)(shu)是(shi)指(zhi)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產(chan)(chan)中用于澆注鑄件(jian)的(de)金(jin)(jin)(jin)屬(shu)(shu)材料(liao)，它是(shi)以(yi)一(yi)種金(jin)(jin)(jin)屬(shu)(shu)元素為(wei)主(zhu)(zhu)要成分(fen)(fen)，并加(jia)入其他金(jin)(jin)(jin)屬(shu)(shu)或非金(jin)(jin)(jin)屬(shu)(shu)元素而(er)組成的(de)合金(jin)(jin)(jin)，習慣上稱為(wei)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合金(jin)(jin)(jin)，主(zhu)(zhu)要有鑄鐵(tie)(tie)、鑄鋼(gang)和(he)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有色合金(jin)(jin)(jin)。叉車配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造型(xing)(xing)(xing)材料(liao)的(de)不同(tong)，又可分(fen)(fen)為(wei)兩大類：一(yi)類以(yi)天然礦(kuang)產(chan)(chan)砂石作(zuo)為(wei)主(zhu)(zhu)要造型(xing)(xing)(xing)材料(liao)，如熔模配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼(ke)型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷(ci)型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一(yi)類以(yi)金(jin)(jin)(jin)屬(shu)(shu)作(zuo)為(wei)主(zhu)(zhu)要鑄型(xing)(xing)(xing)材料(liao)，如金(jin)(jin)(jin)屬(shu)(shu)型(xing)(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心(xin)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車配(pei)(pei)件(jian)鐵(tie)(tie)、低(di)壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。

　　配重塊結(jie)構設計除應符合機器設備本身的(de)(de)要求和機械加工(gong)工(gong)藝(yi)性(xing)的(de)(de)要求外，還應符合鑄造工(gong)藝(yi)的(de)(de)要求，配(pei)重(zhong)塊(kuai)的(de)(de)結(jie)構設計應注意以下幾點(dian)：

　　一、要便于制造(zao)模型、芯盒和造(zao)型：

　　1)配(pei)重塊的外形應力求(qiu)簡單，以便(bian)于起(qi)模(mo)，應盡量使鑄造分型面為平面，且數目小;

　　2)配重塊的(de)內腔應(ying)力(li)求鑄造時(shi)(shi)不用(yong)或少用(yong)型芯(xin)(xin)，當采用(yong)型芯(xin)(xin)時(shi)(shi)，應(ying)方便其支(zhi)撐(cheng)、固定及排氣出砂，時(shi)(shi)應(ying)設有足夠的(de)工(gong)藝孔;

　　3)對(dui)于配重塊內(nei)外側面及加強肋等結構，應在起模方(fang)向設有的(de)結構斜度(du);

　　4)配重塊上的凸(tu)臺部分與(yu)配重鐵本體不應相差(cha)過(guo)大，好取同(tong)一(yi)(yi)高度，同(tong)一(yi)(yi)面(mian)上的距離(li)較近的幾個凸(tu)臺，好連(lian)成整體的凸(tu)起(qi)部分。
