壓片機沖模：沖(chong)(chong)(chong)和模(mo)(mo)(mo)是(shi)壓片機(ji)的基(ji)本部(bu)件，每(mei)副沖(chong)(chong)(chong)模(mo)(mo)(mo)由(you)上沖(chong)(chong)(chong)、中(zhong)(zhong)模(mo)(mo)(mo)、下(xia)沖(chong)(chong)(chong)3個部(bu)件構成。上、下(xia)沖(chong)(chong)(chong)的結構相(xiang)似，其沖(chong)(chong)(chong)頭直(zhi)徑也(ye)相(xiang)等，上、下(xia)沖(chong)(chong)(chong)的沖(chong)(chong)(chong)頭和中(zhong)(zhong)模(mo)(mo)(mo)的模(mo)(mo)(mo)孔相(xiang)配合，可(ke)以(yi)在中(zhong)(zhong)模(mo)(mo)(mo)孔中(zhong)(zhong)自由(you)上下(xia)滑動(dong)，但不會存在可(ke)以(yi)泄漏藥粉的間隙。沖(chong)(chong)(chong)模(mo)(mo)(mo)加工(gong)尺(chi)寸(cun)為(wei)(wei)統一標準尺(chi)寸(cun)，具有(you)互換性。沖(chong)(chong)(chong)模(mo)(mo)(mo)的規(gui)格以(yi)沖(chong)(chong)(chong)頭直(zhi)徑或中(zhong)(zhong)模(mo)(mo)(mo)孔徑來表示，一般為(wei)(wei)5.5-12mm，每(mei)0.5mm為(wei)(wei)一種規(gui)格，共(gong)有(you)14種規(gui)格。

　　沖(chong)頭和沖(chong)模在壓(ya)片過程中受的壓(ya)力很大，常用軸承鋼(如(ru)crl5等)制(zhi)作，并熱(re)處理以提高其硬度。

　　沖頭的(de)(de)類(lei)型很多(duo)，沖頭的(de)(de)形(xing)(xing)(xing)(xing)(xing)狀決(jue)定于(yu)(yu)(yu)(yu)藥(yao)片(pian)(pian)所需的(de)(de)形(xing)(xing)(xing)(xing)(xing)狀。按沖模結構(gou)形(xing)(xing)(xing)(xing)(xing)狀可劃分(fen)為圓形(xing)(xing)(xing)(xing)(xing)、異形(xing)(xing)(xing)(xing)(xing)(包(bao)括多(duo)邊(bian)形(xing)(xing)(xing)(xing)(xing)及(ji)曲(qu)線形(xing)(xing)(xing)(xing)(xing));沖頭斷面的(de)(de)形(xing)(xing)(xing)(xing)(xing)狀有平(ping)面形(xing)(xing)(xing)(xing)(xing)、斜(xie)邊(bian)形(xing)(xing)(xing)(xing)(xing)、淺凹(ao)形(xing)(xing)(xing)(xing)(xing)、深(shen)(shen)凹(ao)形(xing)(xing)(xing)(xing)(xing)及(ji)綜合(he)形(xing)(xing)(xing)(xing)(xing)等。平(ping)面形(xing)(xing)(xing)(xing)(xing)、斜(xie)邊(bian)形(xing)(xing)(xing)(xing)(xing)沖頭用于(yu)(yu)(yu)(yu)壓制(zhi)扁平(ping)的(de)(de)圓柱(zhu)體狀片(pian)(pian)劑(ji)，淺凹(ao)形(xing)(xing)(xing)(xing)(xing)用于(yu)(yu)(yu)(yu)壓制(zhi)雙(shuang)凸面片(pian)(pian)劑(ji)，深(shen)(shen)凹(ao)形(xing)(xing)(xing)(xing)(xing)主(zhu)要(yao)用于(yu)(yu)(yu)(yu)壓制(zhi)包(bao)衣(yi)片(pian)(pian)劑(ji)的(de)(de)芯片(pian)(pian)，綜合(he)形(xing)(xing)(xing)(xing)(xing)主(zhu)要(yao)用于(yu)(yu)(yu)(yu)壓制(zhi)異形(xing)(xing)(xing)(xing)(xing)片(pian)(pian)形(xing)(xing)(xing)(xing)(xing)。為了便于(yu)(yu)(yu)(yu)識(shi)別及(ji)服用藥(yao)品(pin).在沖模端面上(shang)也可以刻制(zhi)出藥(yao)品(pin)名(ming)稱、劑(ji)量(liang)及(ji)縱橫的(de)(de)線條(tiao)等標志(zhi)。壓制(zhi)不同劑(ji)量(liang)的(de)(de)片(pian)(pian)劑(ji)，應(ying)選(xuan)擇大小(xiao)適(shi)宜(yi)的(de)(de)沖模。

　　沖模的(de)(de)種類繁(fan)多，但(dan)我們可(ke)以(yi)根據所使用(yong)設備的(de)(de)不同(tong)(tong)，材料(liao)的(de)(de)不同(tong)(tong)，標(biao)準的(de)(de)不同(tong)(tong)，形狀的(de)(de)不同(tong)(tong)而加以(yi)區分：

　　按制造的(de)(de)材料不(bu)同，有合(he)金(jin)(jin)(jin)鋼沖(chong)模、硬質合(he)金(jin)(jin)(jin)沖(chong)模、陶瓷沖(chong)模、鍍(du)鉻、鍍(du)鈦(tai)沖(chong)模;國產(chan)沖(chong)模常(chang)(chang)見的(de)(de)合(he)金(jin)(jin)(jin)鋼材料為：GCr15，Crl2MoV，CrWuMn，9Mn2V，9CrSi;進(jin)口沖(chong)模常(chang)(chang)見的(de)(de)材料為：A2、O1、S1、S7、PHG.S、PHG-P。

　　壓片機沖模：壓片機模具因其標準及機器款式不同，有單沖壓片機模(mo)具和旋轉壓片機模具之分。單沖壓片機和旋轉式壓片機的沖模根據規格、直徑大小、片劑形狀的不同又可分為圓形沖模和異形沖模。

　　圓(yuan)形(xing)沖模(mo)(mo)：淺弧圓(yuan)沖、深弧圓(yuan)沖、斜平(ping)圓(yuan)沖、純平(ping)圓(yuan)沖異形(xing)沖模(mo)(mo)：除圓(yuan)形(xing)以外的幾何形(xing)狀，諸如橢圓(yuan)形(xing)、鍵形(xing)(膠囊形(xing))、三角形(xing)等具體需(xu)要什么樣的沖模(mo)(mo)，均可(ke)根據需(xu)方(fang)要求定做(zuo)。
