詳(xiang)細(xi)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(jian)里，造(zao)型(xing)(xing)造(zao)芯都實(shi)現了機械化或(huo)自動化。常用的砂型(xing)(xing)造(zao)型(xing)(xing)造(zao)芯設(she)備有高、中、低壓造(zao)型(xing)(xing)機、拋砂機、無箱(xiang)射(she)壓造(zao)型(xing)(xing)機、射(she)芯機、冷(leng)和熱芯盒機等。

　　叉車配重鐵(tie)(tie)工(gong)藝可(ke)分(fen)為(wei)(wei)三個基本部分(fen)，即(ji)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)金(jin)(jin)(jin)屬準備、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)鐵(tie)(tie)金(jin)(jin)(jin)屬是(shi)指配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)生產(chan)中用于(yu)澆(jiao)注鑄(zhu)件(jian)的金(jin)(jin)(jin)屬材(cai)料，它是(shi)以一種金(jin)(jin)(jin)屬元素為(wei)(wei)主要(yao)成分(fen)，并加入其他金(jin)(jin)(jin)屬或非金(jin)(jin)(jin)屬元素而組成的合(he)(he)金(jin)(jin)(jin)，習(xi)慣上稱為(wei)(wei)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)合(he)(he)金(jin)(jin)(jin)，主要(yao)有(you)(you)鑄(zhu)鐵(tie)(tie)、鑄(zhu)鋼和配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)有(you)(you)色合(he)(he)金(jin)(jin)(jin)。叉車(che)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)按造型(xing)(xing)(xing)材(cai)料的不同，又可(ke)分(fen)為(wei)(wei)兩大類：一類以天然礦產(chan)砂(sha)石作(zuo)為(wei)(wei)主要(yao)造型(xing)(xing)(xing)材(cai)料，如熔模配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、殼型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、負(fu)壓(ya)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、泥型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、實型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、陶瓷型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等;一類以金(jin)(jin)(jin)屬作(zuo)為(wei)(wei)主要(yao)鑄(zhu)型(xing)(xing)(xing)材(cai)料，如金(jin)(jin)(jin)屬型(xing)(xing)(xing)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、離(li)心配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、連續配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)、叉車(che)配(pei)(pei)(pei)(pei)件(jian)鐵(tie)(tie)、低壓(ya)配(pei)(pei)(pei)(pei)重(zhong)(zhong)(zhong)(zhong)鐵(tie)(tie)等。

　　配重塊結構(gou)設(she)(she)計(ji)除應(ying)符(fu)合(he)機器設(she)(she)備本(ben)身的要(yao)求(qiu)和機械加工(gong)工(gong)藝性(xing)的要(yao)求(qiu)外，還應(ying)符(fu)合(he)鑄(zhu)造工(gong)藝的要(yao)求(qiu)，配(pei)重塊的結構(gou)設(she)(she)計(ji)應(ying)注意以下幾點：

　　一、要便(bian)于制造模型、芯盒和(he)造型：

　　1)配重塊的外形應力求簡單(dan)，以便于起模，應盡量使鑄造分型面為平面，且數目小;

　　2)配重塊的內(nei)腔應(ying)力求鑄(zhu)造時(shi)不用或少用型(xing)(xing)芯，當采用型(xing)(xing)芯時(shi)，應(ying)方便其(qi)支撐、固(gu)定(ding)及排氣出(chu)砂，時(shi)應(ying)設有(you)足夠(gou)的工(gong)藝孔;

　　3)對于配重塊內外側面及(ji)加強肋等結構(gou)，應(ying)在起模方向設有的結構(gou)斜度;

　　4)配(pei)重塊上的凸臺(tai)部分與配(pei)重鐵本體不應相(xiang)差過(guo)大，好取同(tong)一(yi)(yi)高度(du)，同(tong)一(yi)(yi)面上的距(ju)離較近的幾(ji)個凸臺(tai)，好連(lian)成整體的凸起部分。
