詳細介紹：

　　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(li)，造型造芯都實現了機(ji)械化(hua)或自動化(hua)。常(chang)用的砂(sha)型造型造芯設備有高、中、低壓造型機(ji)、拋砂(sha)機(ji)、無箱射壓造型機(ji)、射芯機(ji)、冷和(he)熱芯盒機(ji)等。

　　叉車配重鐵(tie)(tie)工藝可分為(wei)三(san)個基本部分，即(ji)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)準(zhun)備、鑄(zhu)型(xing)準(zhun)備和(he)鑄(zhu)件處(chu)理。配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)是(shi)指配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產中用于澆(jiao)注(zhu)鑄(zhu)件的金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)材(cai)(cai)料，它(ta)是(shi)以一種金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)元(yuan)素(su)為(wei)主(zhu)要成分，并加入其他金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)或非金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)元(yuan)素(su)而組(zu)成的合(he)(he)金(jin)(jin)(jin)(jin)，習慣上稱(cheng)為(wei)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合(he)(he)金(jin)(jin)(jin)(jin)，主(zhu)要有(you)鑄(zhu)鐵(tie)(tie)、鑄(zhu)鋼和(he)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有(you)色合(he)(he)金(jin)(jin)(jin)(jin)。叉車(che)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造型(xing)材(cai)(cai)料的不同(tong)，又可分為(wei)兩大類：一類以天然礦(kuang)產砂石作為(wei)主(zhu)要造型(xing)材(cai)(cai)料，如熔模(mo)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等(deng);一類以金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)作為(wei)主(zhu)要鑄(zhu)型(xing)材(cai)(cai)料，如金(jin)(jin)(jin)(jin)屬(shu)(shu)(shu)(shu)(shu)型(xing)配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離心配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車(che)配(pei)(pei)件鐵(tie)(tie)、低壓配(pei)(pei)重(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等(deng)。

　　配重塊結構(gou)設(she)計除應(ying)符合機器設(she)備本身的(de)要(yao)求和機械加工(gong)(gong)工(gong)(gong)藝性的(de)要(yao)求外，還應(ying)符合鑄造工(gong)(gong)藝的(de)要(yao)求，配重塊的(de)結構(gou)設(she)計應(ying)注(zhu)意以下(xia)幾點：

　　一、要便(bian)于制造(zao)模型(xing)、芯(xin)盒和造(zao)型(xing)：

　　1)配重塊的外形應(ying)力求(qiu)簡單，以(yi)便于起模，應(ying)盡(jin)量使鑄造分型面為平面，且數(shu)目小;

　　2)配重(zhong)塊的內腔(qiang)應力求鑄(zhu)造時(shi)不(bu)用或(huo)少用型芯(xin)，當(dang)采用型芯(xin)時(shi)，應方便其支撐、固定(ding)及排氣出(chu)砂(sha)，時(shi)應設有足夠的工(gong)藝孔;

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

　　4)配重塊上(shang)的(de)凸臺部(bu)分與配重鐵本(ben)體不(bu)應相差過大，好取(qu)同(tong)一高度，同(tong)一面上(shang)的(de)距離較近的(de)幾個(ge)凸臺，好連(lian)成整體的(de)凸起(qi)部(bu)分。
