詳(xiang)細介紹：

　　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)型造(zao)(zao)芯都實現(xian)了機(ji)械化或自動化。常用的(de)砂(sha)型造(zao)(zao)型造(zao)(zao)芯設備有高、中、低壓(ya)(ya)造(zao)(zao)型機(ji)、拋砂(sha)機(ji)、無箱射(she)壓(ya)(ya)造(zao)(zao)型機(ji)、射(she)芯機(ji)、冷和熱芯盒機(ji)等。

　　叉車配重鐵(tie)(tie)(tie)(tie)(tie)工(gong)藝可分(fen)為(wei)三個基本部分(fen)，即配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金屬(shu)(shu)(shu)準備、鑄(zhu)(zhu)型(xing)(xing)準備和鑄(zhu)(zhu)件處理(li)。配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)金屬(shu)(shu)(shu)是(shi)指配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)生產(chan)中用(yong)于(yu)澆注鑄(zhu)(zhu)件的金屬(shu)(shu)(shu)材(cai)料(liao)，它是(shi)以(yi)(yi)一種金屬(shu)(shu)(shu)元素為(wei)主(zhu)(zhu)(zhu)要(yao)成分(fen)，并(bing)加(jia)入其他金屬(shu)(shu)(shu)或非金屬(shu)(shu)(shu)元素而(er)組成的合金，習慣上稱為(wei)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)合金，主(zhu)(zhu)(zhu)要(yao)有鑄(zhu)(zhu)鐵(tie)(tie)(tie)(tie)(tie)、鑄(zhu)(zhu)鋼和配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)有色合金。叉車配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)按造型(xing)(xing)材(cai)料(liao)的不同，又可分(fen)為(wei)兩(liang)大(da)類(lei)：一類(lei)以(yi)(yi)天然礦產(chan)砂石作為(wei)主(zhu)(zhu)(zhu)要(yao)造型(xing)(xing)材(cai)料(liao)，如熔模配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、殼型(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、負壓(ya)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、泥型(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、實型(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、陶瓷型(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等;一類(lei)以(yi)(yi)金屬(shu)(shu)(shu)作為(wei)主(zhu)(zhu)(zhu)要(yao)鑄(zhu)(zhu)型(xing)(xing)材(cai)料(liao)，如金屬(shu)(shu)(shu)型(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、離心配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、連(lian)續配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)、叉車配(pei)(pei)(pei)(pei)件鐵(tie)(tie)(tie)(tie)(tie)、低壓(ya)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)(tie)(tie)(tie)等。

　　配重塊結(jie)構設(she)計(ji)除應符(fu)(fu)合機器設(she)備本(ben)身的(de)(de)要(yao)求和機械(xie)加工工藝性的(de)(de)要(yao)求外，還應符(fu)(fu)合鑄(zhu)造工藝的(de)(de)要(yao)求，配重(zhong)塊的(de)(de)結(jie)構設(she)計(ji)應注意以下幾(ji)點：

　　一、要便(bian)于(yu)制造(zao)模型、芯盒和造(zao)型：

　　1)配重塊的(de)外形應力求簡單，以(yi)便于起模，應盡量使鑄造分型面(mian)為(wei)平面(mian)，且數(shu)目小(xiao);

　　2)配(pei)重塊的(de)內腔(qiang)應(ying)力求鑄造(zao)時不(bu)用或少用型芯，當采(cai)用型芯時，應(ying)方便其支撐(cheng)、固定及排氣出砂(sha)，時應(ying)設有足夠的(de)工(gong)藝(yi)孔;

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

　　4)配重塊上(shang)的(de)凸臺(tai)部(bu)分(fen)與配重鐵(tie)本(ben)體不(bu)應相差過大，好(hao)取(qu)同一高度，同一面上(shang)的(de)距離較近的(de)幾個凸臺(tai)，好(hao)連成整體的(de)凸起部(bu)分(fen)。
