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)型(xing)造(zao)芯(xin)都實現了機械(xie)化(hua)或自動化(hua)。常用的砂型(xing)造(zao)型(xing)造(zao)芯(xin)設(she)備(bei)有高、中、低壓造(zao)型(xing)機、拋砂機、無箱(xiang)射壓造(zao)型(xing)機、射芯(xin)機、冷(leng)和(he)熱芯(xin)盒機等(deng)。

　　叉車配重鐵(tie)(tie)(tie)工藝可分(fen)(fen)(fen)為(wei)三個(ge)基本(ben)部分(fen)(fen)(fen)，即配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金(jin)(jin)(jin)屬(shu)(shu)準(zhun)備、鑄(zhu)型(xing)準(zhun)備和鑄(zhu)件處理。 配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)金(jin)(jin)(jin)屬(shu)(shu)是指配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)生產(chan)(chan)中(zhong)用于(yu)澆注鑄(zhu)件的金(jin)(jin)(jin)屬(shu)(shu)材料，它是以(yi)一(yi)(yi)種金(jin)(jin)(jin)屬(shu)(shu)元素為(wei)主(zhu)要成分(fen)(fen)(fen)，并加入其(qi)他金(jin)(jin)(jin)屬(shu)(shu)或非(fei)金(jin)(jin)(jin)屬(shu)(shu)元素而組成的合金(jin)(jin)(jin)，習慣上稱為(wei)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)合金(jin)(jin)(jin)，主(zhu)要有(you)鑄(zhu)鐵(tie)(tie)(tie)、鑄(zhu)鋼和配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)有(you)色合金(jin)(jin)(jin)。叉車(che)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)按造型(xing)材料的不(bu)同，又可分(fen)(fen)(fen)為(wei)兩大類：一(yi)(yi)類以(yi)天然礦產(chan)(chan)砂石作(zuo)為(wei)主(zhu)要造型(xing)材料，如熔模配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、殼(ke)型(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、負壓(ya)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、泥型(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、實型(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、陶(tao)瓷型(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等(deng);一(yi)(yi)類以(yi)金(jin)(jin)(jin)屬(shu)(shu)作(zuo)為(wei)主(zhu)要鑄(zhu)型(xing)材料，如金(jin)(jin)(jin)屬(shu)(shu)型(xing)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、離心配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、連續配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)、叉車(che)配(pei)件鐵(tie)(tie)(tie)、低(di)壓(ya)配(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)等(deng)。

　　配重塊結構設(she)計除應(ying)符(fu)合機器設(she)備(bei)本身的要求(qiu)和機械加工(gong)工(gong)藝性的要求(qiu)外，還應(ying)符(fu)合鑄造工(gong)藝的要求(qiu)，配重塊的結構設(she)計應(ying)注意以(yi)下幾(ji)點：

　　一、要便于制造模型、芯盒和造型：

　　1)配(pei)重(zhong)塊的(de)外形(xing)應力求簡單，以便于起模，應盡量使鑄(zhu)造分型(xing)面為平面，且數(shu)目(mu)小;

　　2)配重(zhong)塊的(de)內腔應(ying)力求鑄造時不(bu)用或少(shao)用型芯，當采用型芯時，應(ying)方便其支撐、固(gu)定及(ji)排氣(qi)出砂(sha)，時應(ying)設有足(zu)夠的(de)工藝孔(kong);

　　3)對(dui)于(yu)配重塊內外側面及加強肋等結(jie)構，應在起模方向設有(you)的(de)結(jie)構斜度;

　　4)配(pei)重塊上的凸臺部分(fen)與配(pei)重鐵本體不應相差過大，好(hao)取同一(yi)高(gao)度，同一(yi)面(mian)上的距離較近的幾(ji)個(ge)凸臺，好(hao)連成(cheng)整體的凸起部分(fen)。
