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)(zao)型(xing)造(zao)(zao)芯(xin)都(dou)實(shi)現(xian)了(le)機(ji)(ji)械化(hua)或自動化(hua)。常用的砂型(xing)造(zao)(zao)型(xing)造(zao)(zao)芯(xin)設(she)備有高、中、低壓(ya)(ya)造(zao)(zao)型(xing)機(ji)(ji)、拋(pao)砂機(ji)(ji)、無箱射壓(ya)(ya)造(zao)(zao)型(xing)機(ji)(ji)、射芯(xin)機(ji)(ji)、冷(leng)和熱芯(xin)盒機(ji)(ji)等。

　　叉車配重鐵(tie)(tie)(tie)(tie)(tie)(tie)工藝(yi)可分(fen)為(wei)(wei)(wei)三(san)個基(ji)本部分(fen)，即配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)金(jin)(jin)(jin)(jin)(jin)屬準(zhun)備、鑄(zhu)型(xing)(xing)(xing)準(zhun)備和鑄(zhu)件處理。 配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)金(jin)(jin)(jin)(jin)(jin)屬是指配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)生(sheng)產中用于澆注鑄(zhu)件的(de)金(jin)(jin)(jin)(jin)(jin)屬材(cai)料，它是以一種金(jin)(jin)(jin)(jin)(jin)屬元素為(wei)(wei)(wei)主(zhu)(zhu)要(yao)成(cheng)分(fen)，并加(jia)入其他金(jin)(jin)(jin)(jin)(jin)屬或非金(jin)(jin)(jin)(jin)(jin)屬元素而組成(cheng)的(de)合金(jin)(jin)(jin)(jin)(jin)，習慣上(shang)稱為(wei)(wei)(wei)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)合金(jin)(jin)(jin)(jin)(jin)，主(zhu)(zhu)要(yao)有(you)鑄(zhu)鐵(tie)(tie)(tie)(tie)(tie)(tie)、鑄(zhu)鋼和配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)有(you)色合金(jin)(jin)(jin)(jin)(jin)。叉車(che)(che)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)按造型(xing)(xing)(xing)材(cai)料的(de)不同，又可分(fen)為(wei)(wei)(wei)兩大類(lei)：一類(lei)以天(tian)然礦產砂石作(zuo)(zuo)為(wei)(wei)(wei)主(zhu)(zhu)要(yao)造型(xing)(xing)(xing)材(cai)料，如熔模配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、殼(ke)型(xing)(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、負壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、泥型(xing)(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、實(shi)型(xing)(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、陶瓷型(xing)(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)等;一類(lei)以金(jin)(jin)(jin)(jin)(jin)屬作(zuo)(zuo)為(wei)(wei)(wei)主(zhu)(zhu)要(yao)鑄(zhu)型(xing)(xing)(xing)材(cai)料，如金(jin)(jin)(jin)(jin)(jin)屬型(xing)(xing)(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、離心配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、連續配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)、叉車(che)(che)配(pei)件鐵(tie)(tie)(tie)(tie)(tie)(tie)、低壓配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)(tie)等。

　　配重塊結構設計除應符合機器(qi)設備本身的(de)要求(qiu)(qiu)和機械加(jia)工(gong)工(gong)藝性的(de)要求(qiu)(qiu)外，還應符合鑄造工(gong)藝的(de)要求(qiu)(qiu)，配(pei)重塊的(de)結構設計應注意(yi)以(yi)下幾(ji)點：

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

　　1)配重塊(kuai)的外形應(ying)力求簡(jian)單(dan)，以便于起模，應(ying)盡量(liang)使鑄造分型面為平(ping)面，且數目小;

　　2)配(pei)重塊的內腔應力求鑄(zhu)造時不用或少用型芯(xin)，當采用型芯(xin)時，應方便其支撐、固(gu)定及排氣(qi)出砂，時應設有足夠的工藝孔;

　　3)對于配重塊內外側面及加(jia)強肋等結構(gou)，應在起模方向設有的結構(gou)斜度;

　　4)配(pei)重(zhong)塊上的(de)凸(tu)臺(tai)部分與配(pei)重(zhong)鐵本(ben)體不應相差(cha)過大，好取(qu)同(tong)一高度，同(tong)一面上的(de)距離(li)較近的(de)幾(ji)個凸(tu)臺(tai)，好連(lian)成整體的(de)凸(tu)起部分。
