鑄造模具的一些特點

您(nin)不要以為沖(chong)壓模(mo)具(ju)廠只是一(yi)味的(de)(de)研究和生產沖(chong)壓模(mo)具(ju),這樣的(de)(de)話產品太單一(yi)了,也(ye)沒(mei)有什么發展空間,所以我們也(ye)研究生產其他類型的(de)(de)模(mo)具(ju),比(bi)如說鑄造模(mo)具(ju).

  現在我們告訴您(nin):

  一:鑄件組織致密(mi),機(ji)械性能高;

  二:鑄(zhu)件成形(xing)性好,有利(li)(li)于形(xing)成輪廓(kuo)清晰、表(biao)面光潔的鑄(zhu)件,對于大型薄壁鑄(zhu)件的成形(xing)更為有利(li)(li).

  三:提高(gao)了金屬(shu)液的工藝收(shou)(shou)得率(lv),一般情(qing)況下不需(xu)要冒口,使金屬(shu)液的收(shou)(shou)得率(lv)**提高(gao),收(shou)(shou)得率(lv)一般可達90%.

  四(si):鑄造利用率(lv)非(fei)常高,（85~95%）由于沒有冒口和澆道,澆口較小,因此(ci)可(ke)以(yi)大幅度降低材料(liao)費和加(jia)工(gong)工(gong)時.

  鑄造模(mo)具是指為(wei)了(le)獲得零(ling)件(jian)的(de)結(jie)構外形(xing)(xing),預先用其他輕易(yi)成(cheng)型的(de)材料做(zuo)成(cheng)零(ling)件(jian)的(de)結(jie)構外形(xing)(xing),然后(hou)再在(zai)砂型中放(fang)入模(mo)具,于是砂型中就(jiu)(jiu)形(xing)(xing)成(cheng)了(le)一個和零(ling)件(jian)結(jie)構尺(chi)寸一樣的(de)空(kong)腔(qiang),再在(zai)該空(kong)腔(qiang)中澆(jiao)注流(liu)動性液體,該液體冷(leng)卻凝(ning)固(gu)之(zhi)后(hou)就(jiu)(jiu)能形(xing)(xing)成(cheng)和模(mo)具外形(xing)(xing)結(jie)構完(wan)全一樣的(de)零(ling)件(jian)了(le).
