　　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)(zao)(zao)(zao)型造(zao)(zao)(zao)(zao)芯(xin)都實(shi)現了機(ji)(ji)械(xie)化或自(zi)動化。常用的(de)砂(sha)型造(zao)(zao)(zao)(zao)型造(zao)(zao)(zao)(zao)芯(xin)設備有高、中、低(di)壓(ya)(ya)造(zao)(zao)(zao)(zao)型機(ji)(ji)、拋砂(sha)機(ji)(ji)、無箱射壓(ya)(ya)造(zao)(zao)(zao)(zao)型機(ji)(ji)、射芯(xin)機(ji)(ji)、冷和熱芯(xin)盒機(ji)(ji)等。

　　叉車配重鐵(tie)(tie)(tie)(tie)(tie)工藝可分為三個基(ji)本部分，即(ji)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金(jin)(jin)屬(shu)(shu)準備(bei)、鑄(zhu)型(xing)(xing)準備(bei)和鑄(zhu)件(jian)處理。配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金(jin)(jin)屬(shu)(shu)是指配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)生產中用于澆注鑄(zhu)件(jian)的金(jin)(jin)屬(shu)(shu)材料，它(ta)是以(yi)一(yi)(yi)種金(jin)(jin)屬(shu)(shu)元素(su)為主(zhu)要(yao)成分，并加入其他金(jin)(jin)屬(shu)(shu)或非金(jin)(jin)屬(shu)(shu)元素(su)而組成的合金(jin)(jin)，習(xi)慣上(shang)稱(cheng)為配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)合金(jin)(jin)，主(zhu)要(yao)有(you)鑄(zhu)鐵(tie)(tie)(tie)(tie)(tie)、鑄(zhu)鋼(gang)和配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)有(you)色合金(jin)(jin)。叉車(che)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)按造型(xing)(xing)材料的不(bu)同，又可分為兩大(da)類(lei)：一(yi)(yi)類(lei)以(yi)天然礦產砂石作(zuo)(zuo)為主(zhu)要(yao)造型(xing)(xing)材料，如熔(rong)模配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、殼型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、負壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、泥型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、實型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、陶瓷(ci)型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等(deng);一(yi)(yi)類(lei)以(yi)金(jin)(jin)屬(shu)(shu)作(zuo)(zuo)為主(zhu)要(yao)鑄(zhu)型(xing)(xing)材料，如金(jin)(jin)屬(shu)(shu)型(xing)(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、離心(xin)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、連(lian)續(xu)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、叉車(che)配(pei)(pei)件(jian)鐵(tie)(tie)(tie)(tie)(tie)、低壓(ya)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等(deng)。

　　配重塊結構設(she)計(ji)除(chu)應(ying)符(fu)合機器設(she)備本身的要(yao)求和機械(xie)加工(gong)(gong)工(gong)(gong)藝(yi)性的要(yao)求外，還(huan)應(ying)符(fu)合鑄造工(gong)(gong)藝(yi)的要(yao)求，配重塊(kuai)的結構設(she)計(ji)應(ying)注意以下幾點：

　　一、要便于制造(zao)(zao)模型、芯盒和造(zao)(zao)型：

　　1)配重塊的外(wai)形應(ying)力求簡(jian)單，以便于起模，應(ying)盡量使鑄造分型面為平面，且數目小;

　　2)配重(zhong)塊的內(nei)腔應力求(qiu)鑄造時不用(yong)或少用(yong)型芯，當采(cai)用(yong)型芯時，應方便其(qi)支撐(cheng)、固定及排氣出砂(sha)，時應設有足(zu)夠的工藝孔;

　　3)對于配重塊內(nei)外側面及加強肋等結(jie)構，應在(zai)起模方向設有(you)的結(jie)構斜度;

　　4)配重塊(kuai)上的凸臺(tai)部分(fen)與配重鐵本體(ti)不應相差過大，好取同一高度(du)，同一面(mian)上的距離較近的幾個凸臺(tai)，好連成整體(ti)的凸起部分(fen)。
