注(zhu)塑模具加工(gong)驱(qu)动的几种(zhong)方式

注塑模具(ju)加工运动的驱(qu)动和(he)驱(qu)动力(li)(li)（冲压(ya)力(li)(li)，模具(ju)的锁模力(li)(li)，材料的落锤重，挤(ji)压(ya)力(li)(li)等）是由成形加工机(ji)床和(he)设备的动力(li)(li)经传动机(ji)构提供(gong)的。

机(ji)(ji)电驱(qu)动(dong)：如冲压(ya)机(ji)(ji)、摩擦压(ya)力机(ji)(ji)、辊锻机(ji)(ji)械等，都是(shi)由(you)电动(dong)机(ji)(ji)提供动(dong)力和(he)旋转(zhuan)运动(dong)，以(yi)驱(qu)动(dong)传动(dong)机(ji)(ji)构，并(bing)通(tong)过滑块等和(he)模具运动(dong)部(bu)分进行(xing)连接运动(dong)，以(yi)驱(qu)动(dong)模具定(ding)向运动(dong)，并(bing)把传递的驱(qu)动(dong)力作用(yong)于模具，使(shi)模具对材料进行(xing)成形加(jia)工。

电(dian)液驱(qu)动(dong)(dong)(dong)：即(ji)通(tong)过注塑(su)成型电(dian)动(dong)(dong)(dong)机(ji)驱(qu)动(dong)(dong)(dong)液压(ya)(ya)(ya)泵或水泵产生液压(ya)(ya)(ya)和水压(ya)(ya)(ya)，并(bing)经(jing)过液体的液压(ya)(ya)(ya)输送和控制系(xi)统，产生一定(ding)的额定(ding)压(ya)(ya)(ya)力来驱(qu)动(dong)(dong)(dong)模具(ju)的运动(dong)(dong)(dong)部分（如动(dong)(dong)(dong)模）相连接的液压(ya)(ya)(ya)缸(gang)或者活(huo)塞，驱(qu)使动(dong)(dong)(dong)模相对定(ding)模来进行(xing)(xing)(xing)定(ding)向平移的运动(dong)(dong)(dong)，再(zai)对材料(liao)(liao)进行(xing)(xing)(xing)进一步压(ya)(ya)(ya)缩，使材料(liao)(liao)在进行(xing)(xing)(xing)成形(xing)加工后成为制件

气(qi)(qi)压成(cheng)形(xing)；主要用于吸塑(su)和吹塑(su)成(cheng)形(xing)加(jia)工，即当模具处于固定(ding)状态(tai)(tai)的时(shi)候，经(jing)气(qi)(qi)泵使其产生(sheng)一定(ding)的负压将塑(su)料(liao)板材直接(jie)吸贴(tie)于模具型(xing)面(mian)上(shang)，形(xing)成(cheng)制(zhi)(zhi)件，吹塑(su)则是通过气(qi)(qi)泵产生(sheng)一定(ding)气(qi)(qi)压的气(qi)(qi)体(ti)，吹人热熔态(tai)(tai)塑(su)件或(huo)热熔态(tai)(tai)玻璃制(zhi)(zhi)件毛坯(pi)空腔(qiang)，使其扩展、变(bian)形(xing)，并贴(tie)附在(zai)模具型(xing)腔(qiang)表面(mian)上(shang)，形(xing)成(cheng)制(zhi)(zhi)件。

另外，注塑(su)模(mo)(mo)具(ju)加(jia)工(gong)驱动(dong)比方说铝(lv)合金的(de)型(xing)(xing)材(cai)(cai)(cai)(cai)，塑(su)料型(xing)(xing)材(cai)(cai)(cai)(cai)、片(pian)材(cai)(cai)(cai)(cai)或(huo)薄膜(mo)，一(yi)般都采用挤出成(cheng)形的(de)工(gong)艺(yi)。其模(mo)(mo)具(ju)固定在机头上，材(cai)(cai)(cai)(cai)料以挤压(ya)形式(shi)通过模(mo)(mo)具(ju)，对模(mo)(mo)具(ju)作相对运动(dong)而成(cheng)的(de)各(ge)种制件。如塑(su)料型(xing)(xing)材(cai)(cai)(cai)(cai)是依(yi)靠不停的(de)挤出机器的(de)螺(luo)杆(gan)的(de)螺(luo)旋运动(dong)，将塑(su)料挤入(ru)模(mo)(mo)具(ju)并通过模(mo)(mo)具(ju)的(de)型(xing)(xing)面，经冷却定型(xing)(xing)成(cheng)型(xing)(xing)材(cai)(cai)(cai)(cai)。挤出的(de)型(xing)(xing)材(cai)(cai)(cai)(cai)被牵(qian)引机构向前牵(qian)引，使进(jin)行(xing)连续成(cheng)形加(jia)工(gong)。
