Oomatshini bokubumba inaliti yeplastiki ngoomatshini abafudumeza kwaye baxube iipeliti zeplastiki de zinyibilike zibe lulwelo, oluthi ke luthunyelwe ngesikrufu kwaye lunyanzeliswe kwindawo yokuphuma lube ngumngundo ukuze luqina njengamalungu eplastiki.
Kukho iintlobo ezine ezisisiseko zoomatshini bokubumba, abahlelwe kumandla asetyenziselwa ukutofa iplastiki: i-hydraulic, umbane, i-hybrid hydraulic-electric, kunye ne-injection molders oomatshini.Oomatshini beHydraulic, abasebenzisa iimotor zombane ukunika amandla iimpompo zehydraulic, yayiluhlobo lokuqala loomatshini bokubumba inaliti yeplastiki.Uninzi lomatshini wokubumba inaliti iselulo hlobo.Nangona kunjalo, oomatshini bombane, i-hybrid, kunye noomatshini banokuchaneka ngakumbi.Iimolders zokutofa ngombane, zisebenzisa i-servo motors ezisebenza ngombane, zisebenzisa amandla amancinci, kunye nokuzola kunye nokukhawuleza.Nangona kunjalo, zikwabiza kakhulu kunoomatshini bamanzi.Oomatshini beHybrid basebenzisa umlinganiselo ofanayo wamandla njengeemodeli zombane, kuxhomekeke kumandla aguquguqukayo okuqhuba i-AC odibanisa zombini iidridi zehydraulic kunye neemoto zombane.Okokugqibela, oomatshini bomatshini bonyusa iitoni kwi-clamp ngokusebenzisa inkqubo yokuguqula ukuze kuqinisekiswe ukuba idanyaza akunyuki kwiindawo eziqinileyo.Zombini ezi kunye noomatshini bombane zezona zilungele umsebenzi wegumbi elicocekileyo njengoko kungekho bungozi bokuvuza kwenkqubo yoxinzelelo lwamanzi.
Nganye kwezi ntlobo zoomatshini zisebenza kakuhle kwimiba eyahlukeneyo, nangona kunjalo.Oomatshini bombane balungele ukuchaneka, ngelixa oomatshini be-hybrid banika amandla okubamba ngakumbi.Oomatshini be-hydraulic nabo basebenza ngcono kunezinye iintlobo zokuvelisa iindawo ezinkulu.
Ukongeza kwezi ntlobo, oomatshini beza kuluhlu lweetoni ukusuka kwi-5-4,000 yeetoni, ezisetyenziswa ngokuxhomekeke kwi-viscosity yeplastiki kunye neenxalenye eziza kwenziwa.Oomatshini abasetyenziswa kakhulu, nangona kunjalo, ziitoni ezili-110 okanye iitoni ezingama-250.Ngokwe-avareji, oomatshini abakhulu bokubumba inaliti banokubiza ukusuka kwi-$50,000-$200,000 okanye ngaphezulu.Oomatshini abangama-3,000 beetoni banokuxabisa i-$700,000.Kwelinye icala lesikali, umatshini wokubumba inaliti yedesktop oneetoni ezi-5 zamandla unokubiza phakathi kwe-30,000-50,000 yeedola.
Rhoqo ivenkile yoomatshini iya kusebenzisa kuphela uhlobo olunye lomatshini wokubumba, njengoko amalungu akhethekileyo kuphawu ngalunye- kubiza kakhulu ukutshintsha ukusuka kolunye uhlobo ukuya kolunye (ngaphandle koku ngamacandelo okubumba, ahambelana neempawu ezahlukeneyo. Nganye. oomatshini bohlobo baya kwenza imisebenzi ethile ngcono kuneminye.
Iziseko zoomatshini bokuBumba bePlastiki betofwa
Izinto ezisisiseko zoomatshini bokubumba inaliti yePlasitiki zibandakanya amacandelo amathathu amakhulu: iyunithi yokutofa, i-mold, kunye neyunithi yokudibanisa / i-ejector.Siza kugxininisa kumalungu esixhobo sokungunda inaliti kula macandelo alandelayo, ahlahlela kwi-sprue kunye nenkqubo yembaleki, amasango, iziqingatha ezibini zomngxuma wokungunda, kunye neentshukumo ezikhethiweyo zecala.Unokufunda ngakumbi malunga nenkqubo yokubumba isiseko sokubumba inaliti yeplastiki ngenqaku lethu elinzulu ngakumbi iSiseko sokuBumba isitofu sePlastiki.
1. Umngxuma wokungunda
Umgodi wokungunda ukholisa ukuba namacala amabini: icala elingu-A kunye necala elingu-B.Undoqo (icala le-B) ngokuqhelekileyo aliyiyo into yokuthambisa, icala langaphakathi eliqulethe izikhonkwane ze-ejection ezityhala inxalenye egqityiweyo ngaphandle kokubumba.Umngxuma (A Side) sisiqingatha sokungunda esizaliswe yiplastiki etyhidiweyo.Imingxunya yokungunda ihlala ineendawo zokuvula ezivumela umoya ukuba uphume, nto leyo enokuthi ukuba ibeshushu kakhulu kwaye ibangele amabala okutsha kwiindawo zeplastiki.
2. Inkqubo yeMbaleki
Inkqubo yembaleki ngumjelo odibanisa imathiriyeli yeplastiki enyibilikisiweyo ukusuka kwifidi yesikrufu ukuya kumngxunya wenxalenye.Kwisikhuseli sembaleki ebandayo, iplastiki iya kuqina ngaphakathi kwimisele yembaleki kunye nakwimingxuma yenxalenye.Xa iindawo zikhutshiwe, abagijimi bayakhutshwa ngokunjalo.Iimbaleki zinokuchetywa ngokusebenzisa iinkqubo zezandla ezifana nokucheba ngeefayi cutters.Ezinye iinkqubo zembaleki ezibandayo zikhupha ngokuzenzekelayo abagijimi kwaye ziyingxenye ngokwahlukileyo zisebenzisa i-mold yeplate ezintathu, apho umgijimi uhlukaniswe ngeplate eyongezelelweyo phakathi kwendawo yokutofa kunye nesango lenxalenye.
Imibumbo yeembaleki ezishushu ayivelisi iimbaleki ezincanyathiselweyo kuba imathiriyeli yesondlo igcinwa ikwimeko enyibilikayo ukuya kwinxalenye yesango.Ngamanye amaxesha kuthiwa "amathontsi ashushu," inkqubo yembaleki eshushu inciphisa inkunkuma kwaye iphucula ulawulo lokubumba ngeendleko ezongeziweyo zesixhobo.
3. Iziqhamo
I-Sprues ngumjelo apho iplastiki etyhidiweyo ingena khona ukusuka kumlomo, kwaye ngokuqhelekileyo inqumla kunye nembaleki ekhokelela kwisango apho iplastiki ingena kwimingxuma yokungunda.I-sprue ngumjelo omkhulu wedayamitha kunomjelo wembaleki ovumela ubungakanani obufanelekileyo bemathiriyeli ukuba buhambe ukusuka kwiyunithi yokutofa.Umzobo 2 ongezantsi ubonisa apho i-sprue yenxalenye yokungunda yayilapho iplastiki eyongezelelweyo yaqiniswa khona.
I-sprue ngqo kwisango lomphetho wenxalenye.Iimpawu ze-perpendicular zibizwa ngokuthi "i-cold slugs" kwaye inceda ukulawula ukucheba kwezinto ezingena esangweni.
4. Amasango
Isango livula elincinane kwisixhobo esivumela iplastiki etyhidiweyo ukuba ingene kumgodi wokungunda.Iindawo zesango zihlala zibonakala kwindawo ebunjiweyo kwaye zibonwa njengento encinci erhabaxa okanye into efana nedimple eyaziwa ngokuba yisango lesango.Kukho iintlobo ezahlukeneyo zamasango, ngalinye linamandla kunye norhwebo.
5. Umgca wokwahlulahlula
Umgca wokusahlula ongundoqo welungu elibunjiweyo lenaliti wenziwa xa iziqingatha ezibini zokungunda zisondelelana ukuze zitofwe.Ngumgca obhityileyo weplastiki ojikeleza ngaphandle kwedayimitha yecandelo.
6. Izenzo ezisecaleni
Izenzo zecala zifakelwa kwi-mold evumela ukuba izinto zihambe ngeenxa zonke kuzo zenze i-undercut feature.Izenzo zecala kufuneka kwakhona zivumele ukukhutshwa okuphumelelayo kwenxalenye, ukuthintela i-lock lock, okanye imeko apho inxalenye okanye isixhobo kufuneka sonakaliswe ukususa inxalenye.Ngenxa yokuba iintshukumo ezisecaleni zingalandeli isalathiso sesixhobo ngokubanzi, iimpawu ze-undercut zifuna ii-engile eziyidrafti ezithe ngqo kwintshukumo yentshukumo.Funda ngakumbi malunga neentlobo eziqhelekileyo zezenzo zecala kunye nokuba kutheni zisetyenziswa.
Kwiimolds ezilula ze-A kunye ne-B ezingenayo nayiphi na i-undercut geometry, isixhobo sinokuvala, senze, kwaye sikhuphe inxalenye ngaphandle kweendlela ezongezelelweyo.Nangona kunjalo, iindawo ezininzi zineempawu zoyilo ezifuna isenzo esisecaleni ukuvelisa iimpawu ezifana nokuvuleka, imisonto, iithebhu, okanye ezinye iimpawu.Izenzo ezisecaleni zenza imigca yesibini yokwahlula.
