注塑模具加工驅動的幾種(zhong)方(fang)式

注塑模具(ju)加(jia)工運動(dong)的(de)(de)驅動(dong)和驅動(dong)力(li)（沖(chong)壓力(li)，模具(ju)的(de)(de)鎖模力(li)，材料的(de)(de)落錘重，擠壓力(li)等）是由成(cheng)形加(jia)工機(ji)床(chuang)和設備(bei)的(de)(de)動(dong)力(li)經(jing)傳動(dong)機(ji)構提供的(de)(de)。

機電(dian)驅(qu)(qu)動(dong)(dong)(dong)：如沖(chong)壓機、摩擦壓力(li)機、輥鍛(duan)機械等(deng)，都(dou)是由(you)電(dian)動(dong)(dong)(dong)機提供動(dong)(dong)(dong)力(li)和旋轉運(yun)動(dong)(dong)(dong)，以(yi)驅(qu)(qu)動(dong)(dong)(dong)傳(chuan)動(dong)(dong)(dong)機構，并(bing)通(tong)過滑塊等(deng)和模具(ju)運(yun)動(dong)(dong)(dong)部分(fen)進(jin)行(xing)連接(jie)運(yun)動(dong)(dong)(dong)，以(yi)驅(qu)(qu)動(dong)(dong)(dong)模具(ju)定向運(yun)動(dong)(dong)(dong)，并(bing)把傳(chuan)遞(di)的驅(qu)(qu)動(dong)(dong)(dong)力(li)作(zuo)用于模具(ju)，使(shi)模具(ju)對材料進(jin)行(xing)成形(xing)加工。

電(dian)液(ye)驅(qu)(qu)動(dong)：即通過(guo)注塑成型電(dian)動(dong)機驅(qu)(qu)動(dong)液(ye)壓(ya)(ya)泵或(huo)水泵產生液(ye)壓(ya)(ya)和水壓(ya)(ya)，并經(jing)過(guo)液(ye)體的(de)液(ye)壓(ya)(ya)輸送和控制系統，產生一(yi)定(ding)的(de)額定(ding)壓(ya)(ya)力來(lai)驅(qu)(qu)動(dong)模具的(de)運動(dong)部分（如動(dong)模）相連接的(de)液(ye)壓(ya)(ya)缸或(huo)者活(huo)塞，驅(qu)(qu)使(shi)動(dong)模相對定(ding)模來(lai)進行定(ding)向(xiang)平移的(de)運動(dong)，再對材(cai)料進行進一(yi)步壓(ya)(ya)縮(suo)，使(shi)材(cai)料在進行成形(xing)加工后成為制件

氣壓(ya)成(cheng)(cheng)形(xing)；主要用于(yu)(yu)吸塑和吹(chui)(chui)塑成(cheng)(cheng)形(xing)加工，即當模(mo)具處于(yu)(yu)固定(ding)狀(zhuang)態(tai)(tai)的(de)時候，經氣泵使(shi)其產(chan)生一定(ding)的(de)負壓(ya)將塑料(liao)板材直接吸貼(tie)于(yu)(yu)模(mo)具型面上，形(xing)成(cheng)(cheng)制(zhi)(zhi)件(jian)(jian)(jian)，吹(chui)(chui)塑則是通過氣泵產(chan)生一定(ding)氣壓(ya)的(de)氣體，吹(chui)(chui)人熱熔態(tai)(tai)塑件(jian)(jian)(jian)或(huo)熱熔態(tai)(tai)玻(bo)璃制(zhi)(zhi)件(jian)(jian)(jian)毛坯空(kong)腔(qiang)，使(shi)其擴展、變形(xing)，并貼(tie)附在(zai)模(mo)具型腔(qiang)表(biao)面上，形(xing)成(cheng)(cheng)制(zhi)(zhi)件(jian)(jian)(jian)。

另外，注(zhu)塑模(mo)具(ju)加工(gong)驅動(dong)比(bi)方說鋁合金的(de)(de)(de)型(xing)(xing)(xing)材(cai)(cai)，塑料(liao)(liao)型(xing)(xing)(xing)材(cai)(cai)、片(pian)材(cai)(cai)或薄膜，一(yi)般都(dou)采(cai)用擠(ji)出(chu)成(cheng)形的(de)(de)(de)工(gong)藝。其模(mo)具(ju)固定(ding)在機頭上，材(cai)(cai)料(liao)(liao)以擠(ji)壓形式(shi)通過模(mo)具(ju)，對(dui)模(mo)具(ju)作相對(dui)運動(dong)而成(cheng)的(de)(de)(de)各(ge)種制(zhi)件。如塑料(liao)(liao)型(xing)(xing)(xing)材(cai)(cai)是依靠不(bu)停的(de)(de)(de)擠(ji)出(chu)機器的(de)(de)(de)螺桿的(de)(de)(de)螺旋(xuan)運動(dong)，將(jiang)塑料(liao)(liao)擠(ji)入(ru)模(mo)具(ju)并通過模(mo)具(ju)的(de)(de)(de)型(xing)(xing)(xing)面，經冷(leng)卻(que)定(ding)型(xing)(xing)(xing)成(cheng)型(xing)(xing)(xing)材(cai)(cai)。擠(ji)出(chu)的(de)(de)(de)型(xing)(xing)(xing)材(cai)(cai)被牽(qian)引(yin)(yin)機構向前牽(qian)引(yin)(yin)，使進(jin)行連續成(cheng)形加工(gong)。
