模(mo)溫機又叫(jiao)模(mo)具溫度控制(zhi)機,廣(guang)泛應(ying)用于塑膠(jiao)(jiao)成型,導光(guang)板壓鑄,橡(xiang)膠(jiao)(jiao)輪胎、滾輪,化工反(fan)應(ying)釜、粘合、密煉等各行各業。從廣(guang)義方(fang)面講,叫(jiao)溫度控制(zhi)設備,包(bao)含加(jia)溫和冷凍兩個方(fang)面的(de)溫度控制(zhi)。
現在(zai)模(mo)(mo)溫(wen)(wen)(wen)機一般(ban)分水溫(wen)(wen)(wen)機、油溫(wen)(wen)(wen)機控制(zhi)的(de)溫(wen)(wen)(wen)度(du)可以達(da)到(dao)正負0.1度(du)。標準型(xing)水介質模(mo)(mo)溫(wen)(wen)(wen)機工(gong)作(zuo)較(jiao)高溫(wen)(wen)(wen)度(du)為120℃,高溫(wen)(wen)(wen)型(xing)水介質模(mo)(mo)溫(wen)(wen)(wen)機工(gong)作(zuo)較(jiao)高180℃。水式模(mo)(mo)溫(wen)(wen)(wen)機由于比(bi)較(jiao)干凈,常用于光(guang)學鏡片、注塑成(cheng)型(xing)等(deng)行(xing)業。
油式模(mo)溫(wen)(wen)機(ji)又叫(jiao)油溫(wen)(wen)機(ji)或是油加熱(re)器,油式模(mo)溫(wen)(wen)機(ji)(油溫(wen)(wen)機(ji)):油式模(mo)溫(wen)(wen)機(ji)分(fen)為三個等級(ji):標準型(xing)(xing)、高溫(wen)(wen)型(xing)(xing)、超高溫(wen)(wen)型(xing)(xing),較高工(gong)作溫(wen)(wen)度分(fen)別為180℃,300℃,350℃。
其工作原理:模(mo)溫(wen)(wen)機管路與模(mo)具油道(dao)連接構(gou)成(cheng)回路,導熱油在(zai)泵的作用下進行循環。溫(wen)(wen)度傳感(gan)器將數據(ju)傳送到控(kong)制系統,自動調整加熱/冷(leng)卻動作,控(kong)制導熱油溫(wen)(wen)度。
模溫機在塑膠行(xing)業的運用(yong)比較普遍,主要作(zuo)用(yong)是:
1,提高產品的成(cheng)型效率;
2,降低不良品的產(chan)生;
3,提高(gao)產品(pin)的外觀,抑制產品(pin)的缺陷;
4,加快生產進度,降低能(neng)耗(hao),節約能(neng)源。
模溫機在壓鑄(zhu)行業(ye)的(de)(de)(de)(de)運用也有很大的(de)(de)(de)(de)空(kong)間,特別是(shi)在鎂(mei)合金,鋁合金的(de)(de)(de)(de)制造中(zhong)(zhong),不(bu)平均或(huo)不(bu)適當(dang)的(de)(de)(de)(de)模具(ju)溫度會導(dao)致鑄(zhu)件尺寸不(bu)穩定,在生(sheng)(sheng)產(chan)過程(cheng)中(zhong)(zhong)頂出鑄(zhu)件變(bian)(bian)形(xing),產(chan)生(sheng)(sheng)熱(re)(re)壓力(li)、黏模、表(biao)面凹陷、內縮孔及熱(re)(re)泡等缺陷。對生(sheng)(sheng)產(chan)周(zhou)期也產(chan)生(sheng)(sheng)影(ying)響(xiang),如填充(chong)時(shi)(shi)(shi)間、冷卻時(shi)(shi)(shi)間及噴涂時(shi)(shi)(shi)間都產(chan)生(sheng)(sheng)不(bu)穩定的(de)(de)(de)(de)變(bian)(bian)數。模具(ju)的(de)(de)(de)(de)壽(shou)命(ming)也會因受到過冷過熱(re)(re)的(de)(de)(de)(de)沖擊而(er)導(dao)致昂貴的(de)(de)(de)(de)鋼材產(chan)生(sheng)(sheng)熱(re)(re)裂,加速其老化。
在現(xian)代化的工廠中,因(yin)應市(shi)場的競爭,節省人力(li),提高品質(zhi),降低成本(ben)的經營策(ce)略是(shi)刻不容緩的,模溫機的使(shi)用,可(ke)使(shi)模具(ju)預(yu)熱(re)時間減少,成品表面質(zhi)量提升及(ji)可(ke)完全自(zi)動化生產(chan)。提高模具(ju)壽命是(shi)提高生產(chan)力(li)的必要(yao)手(shou)段。
溫(wen)(wen)(wen)(wen)度控(kong)制機在(zai)(zai)(zai)(zai)其他行業(ye)的(de)運用則是(shi)設備構成的(de)必(bi)然條件,叫法也不同。在(zai)(zai)(zai)(zai)PVC片材輥輪控(kong)溫(wen)(wen)(wen)(wen)中(zhong)(zhong)叫油加熱(re)器(qi),在(zai)(zai)(zai)(zai)擠出機設備中(zhong)(zhong)叫溫(wen)(wen)(wen)(wen)控(kong)裝置,在(zai)(zai)(zai)(zai)橡(xiang)膠密(mi)煉機設備中(zhong)(zhong)叫溫(wen)(wen)(wen)(wen)度控(kong)制系(xi)統或(huo)叫溫(wen)(wen)(wen)(wen)控(kong)機,這些設備中(zhong)(zhong)基(ji)本上是(shi)一個(ge)先快速升溫(wen)(wen)(wen)(wen),然后是(shi)保溫(wen)(wen)(wen)(wen)的(de)過(guo)程。而(er)在(zai)(zai)(zai)(zai)橡(xiang)膠設備中(zhong)(zhong)升溫(wen)(wen)(wen)(wen)后還需(xu)要長期執行一個(ge)降溫(wen)(wen)(wen)(wen)冷卻的(de)過(guo)程。?
