Inaliti (yokubumba) iplastiki (okanye inaliti) yindlela apho iplastiki inyibilikisiwe kwi-cylind yokufudumeza i-syling yejelong yenja, kwaye ikhutshiwe yi-plipple okanye i-screcked i-screw kwi-cavity ye-cavity ye-cavity. . Ayivelisi nje iMveliso ePhezulu, ekumgangatho ophezulu kwimveliso ephezulu, kodwa ikwaneentlobo ezahlukeneyo zeplastiki kunye nokusetyenziswa. Ke ngoko, inaliti yokubumba yenye yeendlela ezibalulekileyo zokubumba kwi-printic.
Imisebenzi esisiseko yomatshini wokubumba
Inaliti ebunjiweyo iphunyezwa ngoomatshini ababunjiweyo.
Imisebenzi esisiseko yoomatshini bokuvimba amantshontsho:
1. Ukufudumeza iplastiki kwimeko etyhidiweyo;
2. Faka uxinzelelo oluphezulu lokunyibilika ukubangela ukuba iphume kwaye igcwalise i-cavity.
Inkqubo / izixhobo
Inaliti ebunjiweyo ye-thermoplastics yenziwa ngamakrowa kwaye izaliswe. Izixhobo ezisetyenziselwa ukwenza izinto kunye nokupholisa kwenziwa umatshini wokuzila, inaliti kunye nezixhobo ezincedisayo (njengokukoma kwezixhobo).
Isixhobo seNqaku
Isixhobo sentsholongwane ikakhulu siyifumana ikakhulu isondo kunye nemitha kwinkqubo yomatshini wokubumba. Inaliti kunye nengcinezelo-ilondolozo kunye neminye imisebenzi. Isixhobo sohlobo lwesikhumba sisetyenziswa kakhulu, kwaye senziwa ngokudibanisa isikroba esikroliweyo kunye nenaliti kwisikrelem esinye.
Eyona nto iphambili, kufuneka ithunyelwe kwi-coaxial i-coaxial inja. Xa isebenza, iplastiki kwi-hopper iwela kwisilinda sokufudumeza ngobunzima bayo. Xa i-screw ijikeleza, iplastiki iqhubela phambili kwi-screw roove. Ngeli xesha, lo mbandela ushushuziwe yi-heater yangaphandle yesilinda yokufudumeza, kwaye iphakathi nayo ikhuselwe. Ubushushu obuveliswe kukunyuka kokusika kwaye iqondo lobushushu liphuma liye kwimo etyhidiweyo.
Ukugcinwa kwento engaphambili kwesilinda esishushu, umkhosi wokuphendula (uxinzelelo lwangasemva) oluveliswa zizixhobo ezityhalela umva, kwaye iswitshi lomda lisetyenziselwa ukunciphisa inani lokubuyela umva. Xa urhoxisa isikhundla esithile, isikhafu sokuyeka ukujikeleza, ngokwenza oko (ukulinganisa) isixa senaliti kube kanye.
Emva kokuba izinto ezenziwayo zipholile, xa sele imveliso ikhutshiwe, ukubumba kuvaliwe kwakhona kwaye inkqubo yentsholongwane iqalile. Ngeli xesha, isilinda se-hydraulic (inaliti yesilinda) yesixhobo se-ijesi isebenza kwiscrew, kwaye phantsi koxinzelelo oluphezulu, isikhafu siba yinto enyibilikisiweyo, kwaye inyibilikisi igcinwe kwi-nozzle .
Isixhobo sokuhlambela isikhumba senziwe ngesikere, umgqomo, i-nozzle kunye nesixhobo esiqhubayo. Isikere senaliti sihlulwe ngokubanzi: ukondla, ukucinezelwa, kunye nemitha, umyinge wokucinezelwa ngu-2 ~ 18.
Xa inyibilikisiwe kwi-nozzle, inxenye yenyibilikisa iya kuvela ngasemva nge-screw groove yesikrelemnqa ngenxa yokunyibilika kwendlela yokuphendula. Ukuthintela oku, ivalve yokutshekisha iqhotyoshelwe ekupheleni kwescrew. Kwi-pulyvinyl pherviny ye-phervinyl enzima, intloko ye-consac isetyenziswa.
I-Barrel yinxalenye yesikali sokulayisha kwaye yenziwa ngokungaxhathisi ubushushu. Yenziwe ngentsimbi ephezulu yokunganyangeki. Uluhlu lwe-heation lombane lufakwe kwi-perifiry yegreyini yokutshisa imixholo ye-borl. Iqondo lobushushu lilawulwa yi-thermocoupple ukunika iplastiki yobushushu efanelekileyo.
I-nozzle yinguqu phakathi kwebarrel kunye ne-subld, efakwe kwi-coil yokufudumeza kuba yinxalenye ebalulekileyo yeplastiki inyibilika ngqo ngqo. Ngokubanzi, inaliti ebumbayo isebenzisa i-nozzles evulekileyo. I-Polyamines ye-Polyasity ephantsi, i-valve ye-nooving isetyenziswa.
Ukujikeleza kwesikhafu se-drive kuya kufezekiswa yimoto yombane okanye yimoto ye-hydraulic, kunye nokuhamba kwesikhethisi se-screw kufezekiswa ngoxinzelelo lwe-hyddraulic.
Iiparamitha zomatshini wokubumba zibonakaliswa sisixhobo sentsholongwane: Isixa senaliti sibhekisa kwinani eliphezulu lomatshini oxutyweyo oswelekileyo kwi-molystyrene nganye, okanye ngumthamo yenyibilikisiwe;
Uxinzelelo lwenaliti lubhekisa kwingcinezelo esetyenziswa kwicandelo lomnqamlezo ngexesha lenaliti ngexesha lenaliti; Isantya sesantya esibonisa isantya esihamba ngesantya esihamba ngesikhafu ngexesha lenaliti.
Isixhobo sokubumba
Ukongeza ekugqibezeni isenzo sokuvula kunye nokuvala i-sold, owona msebenzi uphambili wesixhobo se-molmping kukumelana noxinzelelo oluphezulu lokunyibilikisa kwi-onbult kunye nokuvula.
Nokuba ngaba indlela yokuxoka i-Whopming ye-Whopming yi-Meyilical okanye i-hydraulic okanye i-hydraulic yomatshini, ukuvulwa kokuvuka kunye nokuvalwa kufuneka kube ngathi bhetyebhetye, ukufika ngexesha, ukhawuleza kwaye ukhuselekile kwaye ukhuselekile kwaye ukhuselekile.
Ukusuka kwiimfuno zobugcisa, ukuvulwa kunye nokuvalwa kwemibuliso kufuneka kube nefuthe elibi. Isantya esisebenzayo setemplate kufuneka sicothise kwaye sicothise xa sibakholisa ukubumba, kwaye sicothise kwaye sicothise kwaye sicothise xa uvula ibumba. Ukwenzela ukuthintela ukonakala kwi-mold kunye neenxalenye.
Amandla afakwe kwifreen ngexesha lokwenza inkqubo yokugcina ivaliwe kubizwa ngokuba yimveliso ye-clample, kwaye ixabiso layo kufuneka libe yimveliso yoxinzelelo lwe-cavity kunye nendawo eqikelelweyo ye-Split). Uxinzelelo oluqhelekileyo kwi-cavity ngokubanzi phakathi kwe-20 ne-45 MPA.
Ukusukela kumgca wokubekwa amandla abonisa ubungakanani bemveliso ebumbayo yamatshini wokubumba, awona manyathelo aphezulu enaliti asetyenziselwa ukubonisa imigaqo yomatshini wokubumba, kodwa kukho ubudlelwane obuthile obuthile phakathi kwe ukunyanzelwa kunye nenani lesaliti.
Nangona kunjalo, ukumelwa kwamandla okuMnyama okuxubayo akuthethi ngokuthe ngqo ivolumu yemveliso egciniweyo, kwaye ayilunganga ukuyisebenzisa. Uninzi lwabavelisi behlabathi basebenzisa amandla okuqhwaba / ivolunti yokulingana nenaliti yokubonisa imigaqo yomatshini wokubumba, kwivolumu yenaliti, yoomatshini ohlukeneyo. Kukho umgangatho oqhelekileyo wokuthelekisa, i-theoreting inaliti xa uxinzelelo lwentsholongwane liphinda-phinda i-100MPA, oko kukuthi, ivolumu yokulingana nenaliti.
Inkqubo yokulawula
Inkqubo yokulawula i-hydraulic yomatshini ongcolileyo ye-Ination ikakhulu yahlulwe yinkqubo yokulawula i-hydraulic, inkqubo yokulawulwa kwe-serpo kunye nenkqubo yokulawula.
Ngenxa yobunzima benkqubo ye-hydraulic, inkqubo yokudibana yeoyile ye-valve ye-valve ithathiwe njengomzekelo ukubonisa ulwandlalo. Iimpawu zale nkqubo zezi: Kukho ukuhamba kolawulo kwaye uxinzelelo luloyika izinto ezilinganayo kwi-oyile yesekethe (i-electromagnetic valves okanye i-elektromagnetic ye-encpotines, i-elektromagnetiine yokuhamba).
Ukuhamba komlinganiso onamandla anikwe amandla kwaye amandla alinganayo amagunya e-magneti asetyenziselwa ukulawula isixa-mali sokudlulisela i-valve okanye umkhosi wasentwasahlobo oyiyo ukulawula i-valve okanye uxinzelelo lwe-valve yokulawula inaliti Isantya, isantya sesikhuselo, isantya sokuvula kunye nokuvala isantya kunye nengcinezelo yenaliti. Ukubamba uxinzelelo. I-screw torque. Inaliti yesihlalo se-eva. Uxinzelelo lokukhuselwa kwesikhuselo liyiNqanaba elinye, inqanaba lamanqanaba okanye lingaphezulu.
