1、嘉興昌機械工業(yè)有限公司【注塑機保養(yǎng)手冊】1. 保養(yǎng)及檢查Maintenance and Examination日常保養(yǎng)及檢查機器壽命是非常重要,預(yù)防重于治療，然而對于機器而言，當(dāng)然是保養(yǎng)重于修理了，射出成型機是一種高運轉(zhuǎn)的機器，一天可能接近 24 小時操作，若以一個月 25 個工作天而言，每一月累積 600 個操作小時，一年將達(dá) 7200 小時，幾乎是一般工具機4-5 倍長之操作時間。 保持良好的保養(yǎng)是減少及防止機器發(fā)生故障的最有效途徑。以下資料提供給用戶 , 使用機器時必須仔細(xì)閱讀, 給機器定期檢查保養(yǎng)及維護(hù).It is important to maintain and examine t

2、he machine everyday. We are alwaystoldthatpreventionis betterthan cure,as well as machine, maintenance is betterthan repair. Injection molding machine as a kind of high operation machines, maywork near 24 hours in one day, ifitkeep working 25 days every month, then itwillaccumulate 600 operation hou

3、rs within a month,7200 hours in a year, which is 4-5times longer than general machine. Maintaining a good maintenance is the mosteffective way to reduce and prevent the malfunction of machine. The followinginformation is provided to user, and please keeps careful reading before using the machine as

4、well as examines and maintains regularly.1.1 清洗 Washing機器經(jīng)過長時間使用后 , 所有滑動導(dǎo)桿、油缸的軸芯、滑面等會被沙塵等物質(zhì)沾污 , 若不及時清理 , 滑動導(dǎo)桿、油缸軸芯及滑面會容易磨損 , 尤其對油缸軸芯油封為甚。保持清潔可防止由雜物引起磨損、堵塞、水份引起的銹蝕和及早發(fā)覺漏油情況。所以經(jīng)常要清洗機器。請勿使用酒清、揮發(fā)性油、汽油、石油等制品擦拭人機屏幕，必須使用一般家庭擦試玻璃用清潔劑擦拭。Aftera long time using,allthe slidinglead-screw 、axis core of oilcylinde

10、face, and dry friction is not allowed, filling grease in time.1.3 液壓系統(tǒng) Hydraulic pressure system液壓油箱必須經(jīng)常存有足夠液壓油, 可從裝置于油箱外之油尺檢查油位, 如果發(fā)覺油位低于要求 ,應(yīng)及補充。Hydraulicfluidtank shouldbe oftenstoring withenoughhydraulicoil, andoillevelcanbeexaminedbyusingthedipstickwhich isfixedoutsidethe oilbox. If finding tha

11、t oil level is lower than requirement,it should be replenished in time., 應(yīng)采用高質(zhì)素之液壓油 , 液壓油在攝氏很多液壓系統(tǒng)毛病起源于已污染之液壓油30-50 度, 粘度在 150-225SUS或動動粘度 40-60厘澌最為適合。本司推薦使用46#液壓油 .Lots of errorsof hydraulicsystem originate from the pollutedhydraulicoil,so high qualityhydraulicoil isbetter.The suitablestateof thehy

12、draulicoilis in30-50 degree（temperature ）、150-225SUS（viscosity ）and 40-60ls (kinematicviscosity).Our company recommends #46 of hydraulic oil.用戶亦須定期檢查液壓油，若果需要更換液壓油，把原有液壓油抽掉，清洗油箱后，再加注全新液壓油于油箱內(nèi)（新舊液壓油不能混合）, 同時清洗油篩。Users also should check the hydraulicoilregularly. If it needs to renewalthe hydraulic oil

13、, firstly, take out the original hydraulic oil and wash thetank. And then in pour the new hydraulic oil (oil and new hydraulic oil can notbe mixed together.), wash the oil screen at the same time.機器在正常運作時，液壓系統(tǒng)溫度不能超過攝氏55 度。在超過情況下工作，液壓系統(tǒng)會產(chǎn)生以下現(xiàn)象：When the machine works regularly, the temperature of hydr

14、aulic pressure system can not overtake 55 degree. If it is exceeded, the hydraulic pressure system will come with the follow phenomenon:（一）液壓油氧化加速，提前變質(zhì)。Oxidation of hydraulic oil is accelerated, and deteriorate in advance.（二）粘度降低導(dǎo)致油泵及其他閥體受損.Viscosity reducing cause damage to pumps and other parts.（三

15、）油封加快老化。Oil seal accelerate to ageing.若發(fā)覺 If find that（一）液壓油出泡沫If hydraulic oil bubble,（ 1）應(yīng)檢查油泵吸油管的密封性。Check the leak-tightness of the oil pump suction pipe.（ 2）應(yīng)檢查液壓油是否充足。Check the hydraulic oil whether it is sufficient.（ 3）應(yīng)檢查回油管是否沉入液壓油內(nèi)。Check back the oil tube whether it is sinking into the hydr

16、aulic oil.（二） 液壓油呈懸浮狀態(tài)白色I(xiàn)f hydraulic oil appear in white suspended state,（ 1） 應(yīng)檢查油箱密封性，可能由于空氣潮濕，空氣中水氛進(jìn)入液壓油內(nèi)。Check the leak-tightness of the oil tank whether liquid watercontent in the air get into the hydraulic oil.（ 2） 應(yīng)檢查熱閃換器水管是否損壞導(dǎo)致冷卻水混入液壓系統(tǒng)內(nèi)。Check the Hot Flash Converter water pipe whether it is

17、 damage resulting in cooling water mixing into the hydraulic system.1.4 液壓泵及液壓閥Hydraulic pump and hydraulic valve由于液壓泵及液壓閥結(jié)構(gòu)精密及復(fù)雜, 維修保養(yǎng)必須由技術(shù)人員處理。裝拆時，要加倍小心以免損壞零件。Due to the precision and complex of hydraulic pump and hydraulic valve structures, maintenance and repair must be dealt with by the technic

18、al staff. When assemble and disassemble, be careful so as not to damage the parts.s1.5 油隔 Grease trap油隔功能是把液壓油被油泵吸入前經(jīng)過油隔而過濾異物。必須經(jīng)常檢查油隔，若油隔嚴(yán)重受污染油泵吸油管產(chǎn)生真空導(dǎo)致油泵損壞。The function of the grease trap is that filters the foreign matter before hydraulic oil being sucked by the oil pump. Check the grease trap u

19、sually, andif the grease trap is polluted seriously, the oil pump suction pipe will emerge vacuum causing the oil pump damaged.1.6油封 Grease seal所有密封填充圈是裝于油缸及閥體上, 當(dāng)密封圈損壞時 , 會影響機器工作性能 , 甚至泄油。需要時，應(yīng)及早更換損壞之密填封圈。Allsealed filledcircles are installedon the oiltank and valve body, andwhen the sealed circles

20、is damaged, itwillaffect theperformance of the machineand even oil drainage.1.7電路控制 Circuit control在正常運作時 , 防止水及其他雜物進(jìn)入電箱, 電箱門應(yīng)緊密關(guān)閉 . 遇到電路故障時應(yīng)由合資格的工作人員負(fù)責(zé)維修。臺電部份聯(lián)接螺絲應(yīng)緊固，防止因松脫而導(dǎo)致危險。經(jīng)常檢查電箱溫度不能太高，防止影響電子零件的正常運作。同時定期檢查安全門電器互鎖及行程咭掣以免發(fā)生意外。In normal operation, prevent water and other debris getting box and th

21、e door of the electric box should be closed tightly.intoWhenitthe electricencountersa circuit fault, eligible staff should be responsible for maintenance.1.8 電熱 Electric heat應(yīng)經(jīng)常檢進(jìn)電熱 . 電熱不正常會產(chǎn)生注塑總是導(dǎo)致產(chǎn)品質(zhì)素低.Check the electric heat regularly. Abnormal electric heat can produce plastic injection resultin

22、g in a low quality of product.（一）檢查積各段電熱是否正常。Check each part of electric heat whether it is normal.（二）檢查溫度控制狀態(tài)。Check the control status of the temperature.（三）檢查控溫線端與熔膠筒接觸狀況。Check the contact status between temperature control terminal and melt adhesive cylinder.1.9熔膠筒及螺桿更換聯(lián)結(jié)Melt adhesive cylinder an

23、d screw replacing the coupling assembly（一）對射咀進(jìn)行拆除或移開，必須先淺放掉料管內(nèi)部的塑料產(chǎn)生的壓力。Beforedismantlingor removing the shoot mouth, pressureproduced by the plasticinsidethe material pipe should be unhanded lightly.因為有時溫度會對封閉式料管內(nèi)部的塑膠產(chǎn)生化學(xué)反應(yīng)，并于料管內(nèi)產(chǎn)爆炸性的壓力。Because that sometimes temperature can lead to that plastic ta

24、ke place chemical reactions and cause a explosive pressure inside the closed material tube.將料管的溫度降下及降低內(nèi)部的壓力，按下松退鍵讓螺桿向后退。Pressing the loose back key and making the screw back can lower the temperature and pressure inside the material tube.（二）塑膠于料管內(nèi)加熱時間太長是相當(dāng)?shù)奈ｋU的，因為長時間的對塑膠加溫產(chǎn)生的毒的氣體，并經(jīng)由射嘴噴出來。It is dange

25、rous to heat the plastic cement inside the material tube too long time.Because of that long time heating the plastic will produce the toxic gases and spraying out from the shoot mouth.（三）料咀跑入異物時，不可以加高溫度或高壓力將體更擠出來。If there s some foreign matter come from the material mouth, do not rise up the tempera

26、ture and pressure to squeeze it out strongly.必須關(guān)掉電源并將漏斗內(nèi)時，然后再將異物清除。Turn off the power and use a funnel to clear the foreign matter.（四）當(dāng)硬物掉入送料漏斗時， ，要取出時必須相當(dāng)?shù)男⌒?。If the hard objects fall down into the feed funnel, pay more attention when take it out.（五）拆下料管的護(hù)蓋前必須先確認(rèn)關(guān)閉總電源開關(guān)。Be sure the main power is off

27、 before removing the material tube s cover.（六）嚴(yán)禁將潤滑油涂抹于射出螺桿、料管、電熱片上。Lubricant applied to injection screw、 material tube、electric flake is forbidden.（七）清洗或更換零件時，必須拆除熔膠筒、螺桿及止逆閥等零件。先選擇手動方式。Washor change the parts, must dismantle melt adhesive cylinder 、screw and lock check gate first. Select manually f

32、d drive shaft.5) 拆除射咀及射咀法蘭。Remove the shooting mouth and shooting mouth flange.6) 操作螺桿“倒索“動作把螺桿端與傳動軸脫離，必要時，用木方枕著螺桿端與傳動軸之間。Use the“fall cable ” movement of the operation screw to separate the screw terminal and drive shaft. If necessary, pillow with a squared timber between screw terminal and drive s

33、haft.7) 操作射膠動作把螺桿推出。Pull the screw out by the operation injection action.注意 : 為安全起見 , 把射膠壓力及速度數(shù)值調(diào)低, 由于熔膠筒已被加熱 , 拆除時小心被燙傷。Note: for security, lower the numerical of injection pressure and speed. As the melt adhesive cylinder is heated, be careful when dismantle.本機螺桿前端裝有標(biāo)準(zhǔn)型之止逆閥組件，止逆閥組件采用左牙螺紋與螺桿連接。當(dāng)螺桿轉(zhuǎn)

34、動時不容易把止逆閥松出，松脫時請留意旋向 .There is a standard lock check gate which is use the left tooth screw thread to connect with screw on this machine. When turning around the screw, if it is not easy to loose the lock check gate. Pay attention to the turn when doffing.1.10 定期檢查 Regular checking（一）每天檢查一次Check it
