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，造型(xing)造芯(xin)都實現了(le)機(ji)(ji)(ji)械化或自動化。常用的砂(sha)型(xing)造型(xing)造芯(xin)設備有(you)高、中、低壓造型(xing)機(ji)(ji)(ji)、拋砂(sha)機(ji)(ji)(ji)、無箱射壓造型(xing)機(ji)(ji)(ji)、射芯(xin)機(ji)(ji)(ji)、冷和熱(re)芯(xin)盒機(ji)(ji)(ji)等。
叉車配重鐵(tie)工藝(yi)可分(fen)(fen)(fen)為(wei)(wei)三個基本(ben)部(bu)分(fen)(fen)(fen)，即配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)金(jin)屬(shu)(shu)準備、鑄(zhu)(zhu)型準備和鑄(zhu)(zhu)件(jian)處理。 配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)金(jin)屬(shu)(shu)是(shi)指(zhi)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)生(sheng)產中用于澆注鑄(zhu)(zhu)件(jian)的(de)金(jin)屬(shu)(shu)材(cai)料(liao)，它是(shi)以一種金(jin)屬(shu)(shu)元素(su)為(wei)(wei)主(zhu)(zhu)要(yao)(yao)成分(fen)(fen)(fen)，并(bing)加入其他金(jin)屬(shu)(shu)或非金(jin)屬(shu)(shu)元素(su)而組成的(de)合金(jin)，習慣上稱為(wei)(wei)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)合金(jin)，主(zhu)(zhu)要(yao)(yao)有鑄(zhu)(zhu)鐵(tie)、鑄(zhu)(zhu)鋼和配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)有色(se)合金(jin)。叉車配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)按造型材(cai)料(liao)的(de)不同，又可分(fen)(fen)(fen)為(wei)(wei)兩大(da)類(lei)(lei)：一類(lei)(lei)以天然礦產砂(sha)石作(zuo)為(wei)(wei)主(zhu)(zhu)要(yao)(yao)造型材(cai)料(liao)，如熔模(mo)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、殼(ke)型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、負壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、泥型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、實型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、陶瓷型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)等(deng);一類(lei)(lei)以金(jin)屬(shu)(shu)作(zuo)為(wei)(wei)主(zhu)(zhu)要(yao)(yao)鑄(zhu)(zhu)型材(cai)料(liao)，如金(jin)屬(shu)(shu)型配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、離心配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、連續配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)、叉車配(pei)(pei)件(jian)鐵(tie)、低壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)等(deng)。
配重塊結構設計(ji)除(chu)應符合機器(qi)設備本身的要(yao)求(qiu)和機械加工工藝(yi)性的要(yao)求(qiu)外，還應符合鑄造(zao)工藝(yi)的要(yao)求(qiu)，配重塊的結構設計(ji)應注(zhu)意以下幾點：
一、要便于(yu)制造模型、芯盒和(he)造型：
1)配重塊的外形(xing)應力求簡(jian)單，以便于起模，應盡量使鑄造分(fen)型(xing)面為平面，且數目(mu)小;
2)配(pei)重(zhong)塊的內腔應(ying)力(li)求鑄(zhu)造(zao)時(shi)不用或少(shao)用型(xing)芯，當采用型(xing)芯時(shi)，應(ying)方便其支撐、固定及(ji)排氣出砂，時(shi)應(ying)設(she)有足夠的工藝孔;
3)對于(yu)配重塊內外側面及加(jia)強肋等結(jie)構(gou)，應在起模(mo)方向設(she)有的結(jie)構(gou)斜(xie)度;
4)配(pei)重塊(kuai)上的(de)凸臺(tai)部分與配(pei)重鐵本體不應相(xiang)差(cha)過大，好取同一高度，同一面上的(de)距(ju)離較近的(de)幾個凸臺(tai)，好連成整體的(de)凸起部分。
