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)(zao)型(xing)造(zao)(zao)芯(xin)(xin)都(dou)實現(xian)了機械化(hua)(hua)或(huo)自動化(hua)(hua)。常(chang)用的砂(sha)(sha)型(xing)造(zao)(zao)型(xing)造(zao)(zao)芯(xin)(xin)設(she)備有高、中、低壓造(zao)(zao)型(xing)機、拋砂(sha)(sha)機、無箱射壓造(zao)(zao)型(xing)機、射芯(xin)(xin)機、冷和熱芯(xin)(xin)盒機等。
叉車配重鐵(tie)(tie)工藝可分(fen)為(wei)三(san)個基本部分(fen)，即配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)準備、鑄(zhu)型(xing)(xing)(xing)準備和鑄(zhu)件(jian)處理。 配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)屬(shu)(shu)是指配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產(chan)中用于澆注鑄(zhu)件(jian)的(de)金(jin)(jin)屬(shu)(shu)材(cai)料(liao)，它是以一(yi)(yi)種(zhong)金(jin)(jin)屬(shu)(shu)元素(su)為(wei)主(zhu)要(yao)成分(fen)，并(bing)加入(ru)其他(ta)金(jin)(jin)屬(shu)(shu)或非(fei)金(jin)(jin)屬(shu)(shu)元素(su)而組成的(de)合(he)(he)(he)金(jin)(jin)，習慣上稱(cheng)為(wei)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合(he)(he)(he)金(jin)(jin)，主(zhu)要(yao)有(you)鑄(zhu)鐵(tie)(tie)、鑄(zhu)鋼和配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有(you)色合(he)(he)(he)金(jin)(jin)。叉車配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造(zao)型(xing)(xing)(xing)材(cai)料(liao)的(de)不同，又可分(fen)為(wei)兩大類(lei)：一(yi)(yi)類(lei)以天然礦產(chan)砂(sha)石作(zuo)為(wei)主(zhu)要(yao)造(zao)型(xing)(xing)(xing)材(cai)料(liao)，如(ru)熔(rong)模配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓(ya)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實(shi)型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一(yi)(yi)類(lei)以金(jin)(jin)屬(shu)(shu)作(zuo)為(wei)主(zhu)要(yao)鑄(zhu)型(xing)(xing)(xing)材(cai)料(liao)，如(ru)金(jin)(jin)屬(shu)(shu)型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心(xin)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車配(pei)(pei)(pei)(pei)件(jian)鐵(tie)(tie)、低(di)壓(ya)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。
配重塊結(jie)(jie)構(gou)設計(ji)除(chu)應(ying)(ying)符合機器設備本身的要(yao)求和機械加工(gong)工(gong)藝(yi)性(xing)的要(yao)求外，還應(ying)(ying)符合鑄造工(gong)藝(yi)的要(yao)求，配重塊的結(jie)(jie)構(gou)設計(ji)應(ying)(ying)注意(yi)以下幾點：
一、要便于制造(zao)模型、芯盒和造(zao)型：
1)配重(zhong)塊的外形應力求簡單(dan)，以便于起(qi)模，應盡量使(shi)鑄造分型(xing)面(mian)為(wei)平面(mian)，且數目(mu)小;
2)配重塊的(de)內腔(qiang)應力求鑄造時(shi)不(bu)用(yong)或少用(yong)型芯，當采用(yong)型芯時(shi)，應方便其(qi)支撐(cheng)、固定及排氣出砂，時(shi)應設有足夠的(de)工藝孔;
3)對(dui)于配重塊內外側面(mian)及(ji)加強肋等(deng)結(jie)構，應在起(qi)模方向設有的結(jie)構斜度;
4)配重(zhong)塊上的凸臺部分與配重(zhong)鐵本(ben)體不應相差過(guo)大，好(hao)取同一高度(du)，同一面上的距離較近的幾個(ge)凸臺，好(hao)連成整體的凸起部分。
