模溫機又叫(jiao)模具溫度控(kong)制(zhi)(zhi)機,廣(guang)泛(fan)應用于(yu)塑膠(jiao)成型,導(dao)光板壓鑄,橡膠(jiao)輪(lun)胎、滾(gun)輪(lun),化(hua)工(gong)反應釜、粘(zhan)合、密(mi)煉等(deng)各行各業。從廣(guang)義方面(mian)講,叫(jiao)溫度控(kong)制(zhi)(zhi)設備,包含加溫和(he)冷凍兩(liang)個方面(mian)的溫度控(kong)制(zhi)(zhi)。
現在模(mo)溫(wen)(wen)(wen)機(ji)(ji)一般(ban)分水(shui)溫(wen)(wen)(wen)機(ji)(ji)、油溫(wen)(wen)(wen)機(ji)(ji)控(kong)制(zhi)的溫(wen)(wen)(wen)度(du)可以達到(dao)正(zheng)負(fu)0.1度(du)。標(biao)準型水(shui)介質模(mo)溫(wen)(wen)(wen)機(ji)(ji)工(gong)作(zuo)較(jiao)高(gao)溫(wen)(wen)(wen)度(du)為120℃,高(gao)溫(wen)(wen)(wen)型水(shui)介質模(mo)溫(wen)(wen)(wen)機(ji)(ji)工(gong)作(zuo)較(jiao)高(gao)180℃。水(shui)式模(mo)溫(wen)(wen)(wen)機(ji)(ji)由于比較(jiao)干凈,常用于光學(xue)鏡片(pian)、注(zhu)塑成型等(deng)行業(ye)。
油(you)式模(mo)溫(wen)機(ji)又叫油(you)溫(wen)機(ji)或是油(you)加熱器,油(you)式模(mo)溫(wen)機(ji)(油(you)溫(wen)機(ji)):油(you)式模(mo)溫(wen)機(ji)分(fen)為三個等級(ji):標準型(xing)、高溫(wen)型(xing)、超高溫(wen)型(xing),較(jiao)高工作溫(wen)度(du)分(fen)別為180℃,300℃,350℃。
其工(gong)作(zuo)原(yuan)理:模溫(wen)機管路與模具(ju)油(you)道連接構成(cheng)回路,導熱(re)油(you)在泵的作(zuo)用下進(jin)行循環。溫(wen)度傳感器(qi)將數(shu)據(ju)傳送(song)到(dao)控(kong)制(zhi)系統,自動(dong)調整加熱(re)/冷卻動(dong)作(zuo),控(kong)制(zhi)導熱(re)油(you)溫(wen)度。
模溫機在(zai)塑膠行(xing)業的運用比較普遍,主要作(zuo)用是:
1,提高產品的成型效(xiao)率;
2,降低(di)不良品的(de)產生;
3,提高產品(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(ji)在(zai)壓鑄行業的(de)運用也有很大的(de)空(kong)間(jian)(jian),特別是(shi)在(zai)鎂合金,鋁合金的(de)制造中(zhong),不平均或不適當(dang)的(de)模具(ju)溫度會導致鑄件(jian)尺(chi)寸不穩定,在(zai)生(sheng)(sheng)產(chan)過(guo)(guo)程中(zhong)頂出鑄件(jian)變(bian)形,產(chan)生(sheng)(sheng)熱(re)壓力、黏模、表面(mian)凹陷、內(nei)縮(suo)孔及熱(re)泡等(deng)缺陷。對生(sheng)(sheng)產(chan)周(zhou)期也產(chan)生(sheng)(sheng)影響,如填充(chong)時(shi)間(jian)(jian)、冷卻時(shi)間(jian)(jian)及噴涂時(shi)間(jian)(jian)都產(chan)生(sheng)(sheng)不穩定的(de)變(bian)數。模具(ju)的(de)壽(shou)命也會因(yin)受到過(guo)(guo)冷過(guo)(guo)熱(re)的(de)沖(chong)擊而導致昂貴的(de)鋼材產(chan)生(sheng)(sheng)熱(re)裂,加(jia)速其老化。
在現(xian)代化的(de)工(gong)廠中,因應市場的(de)競爭,節省人力,提(ti)高(gao)品質(zhi),降低(di)成本(ben)的(de)經營策略是刻不容緩的(de),模溫機的(de)使用,可使模具預(yu)熱時間減少,成品表面質(zhi)量(liang)提(ti)升及可完全自(zi)動(dong)化生產(chan)(chan)。提(ti)高(gao)模具壽命是提(ti)高(gao)生產(chan)(chan)力的(de)必要(yao)手段。
溫(wen)(wen)度(du)(du)控(kong)(kong)(kong)制機在(zai)(zai)其他行業(ye)的運(yun)用則是設(she)備(bei)(bei)構(gou)成的必然條件,叫(jiao)(jiao)法也不同(tong)。在(zai)(zai)PVC片材(cai)輥(gun)輪控(kong)(kong)(kong)溫(wen)(wen)中(zhong)叫(jiao)(jiao)油加熱(re)器,在(zai)(zai)擠出機設(she)備(bei)(bei)中(zhong)叫(jiao)(jiao)溫(wen)(wen)控(kong)(kong)(kong)裝置,在(zai)(zai)橡膠(jiao)密煉機設(she)備(bei)(bei)中(zhong)叫(jiao)(jiao)溫(wen)(wen)度(du)(du)控(kong)(kong)(kong)制系統或叫(jiao)(jiao)溫(wen)(wen)控(kong)(kong)(kong)機,這(zhe)些(xie)設(she)備(bei)(bei)中(zhong)基本上是一個先快速升(sheng)溫(wen)(wen),然后是保溫(wen)(wen)的過程(cheng)。而在(zai)(zai)橡膠(jiao)設(she)備(bei)(bei)中(zhong)升(sheng)溫(wen)(wen)后還需(xu)要長期執行一個降(jiang)溫(wen)(wen)冷卻的過程(cheng)。?
