I-Plastic Injection Molding iyinqubo yokusebenzisa ingcindezi ephezulu ukusunduza ipulasitiki encibilikisiwe ibe isikhunta. Inhloso eyinhloko ukudala imikhiqizo ewusizo lapho ipholile futhi iqina esimweni esisethwe kusikhunta.

An isikulufu sokujova isetshenziswa kabanzi kule nqubo ngenxa yokuguquguquka kwayo ekudaleni izimo nosayizi abahlukene phakathi nomjikelezo owodwa, okunciphisa izindleko zizonke zemikhiqizo ebunjiwe.

Isikulufu sidonsela ipulasitiki esikhunjeni, futhi ijometri yayo inquma ingxenye yejometri - ethinta ngokuqondile isikhathi somjikelezo. Isikhathi somjikelezo omude sibiza imali eningi kunesingeqi isikhathi esithile. Umgomo uwukunciphisa izindleko zokukhiqiza kuyilapho kugcinwa ikhwalithi yomkhiqizo ngokuphuma kwevolumu ephezulu.

Abakhiqizi abaningi basikisela ukusebenzisa izikulufu ezenziwe ngezinto ezifanayo njengomkhiqizo wokugcina, kodwa lokhu kungandisa izindleko nesikhathi sokumaketha.

Izikulufu ezihamba phambili zokubumba umjovo wepulasitiki yilezo ezingadluli izikhathi zomjikelezo futhi zinciphise itorque edingekayo kuwo wonke umjovo. Kudingeka futhi adalwe ngokulungiswa okuncane.

Kunezinhlobo eziningi zezikulufu ezitholakalayo emakethe, kodwa ezinye zingcono kwezinye izinhlelo zokusebenza kunezinye.

Kukhona futhi izinhlobo ezahlukene zepulasitiki ongazisebenzisa ekubumbeni umjovo. Enye yepulasitiki ethandwa kakhulu ukusetshenziswa ekubumbeni umjovo yi ipulasitiki enayiloni ngenxa yokuqina kwayo kanye nobubanzi bokusetshenziswa kwayo. Kuhle kakhulu ekuthwaleni nasekufakeni izicelo futhi ishintsha ngokushesha izinsimbi eziningi embonini yokukhiqiza.

Nalu uhlu lwezikulufu ezingcono kakhulu zokujova laphaya:

Isikulufa Esibuyiselanayo

Isikulufu esiphindaphindayo singesinye sezikulufu ezivame kakhulu ezitholakala ekubumbeni umjovo, futhi sisetshenziselwa izinhlelo zokusebenza ezijwayelekile.

Lesi sikulufu sihlanganisa ingxenye yangaphandle enobubanzi obuhluka phakathi kuka-50% ngaphambi kokuqala kwentambo ukuya ku-10% ekupheleni kwayo, okunikeza ukuncibilika okufanele nokugeleza kwepulasitiki. Lolu hlobo lwesikulufu nalo luyazihlanza, ngakho-ke lungakwazi ukususa izinsalela zezinto ezakhiwe.

Izinto ezisetshenziswayo zibe sezidlula endaweni yokucindezela ngomfutho ophezulu, lapho zixutshwa khona nokushisa bese ziphoqelelwa eziteshini zomgqomo ukuze zijovwe. Okunye okungalungile kulesi sikulufu ukuthi sidinga ukunakekelwa okwengeziwe kunezinye izinhlobo.

I-Cavity Screw

Lesi sikulufu sinentambo ephindwe kabili, ehlinzeka ngokugeleza kwepulasitiki okuhle kakhulu. Iphinde ibe nengxenye yangaphandle enobubanzi obungashintshi buka-20% kuya ku-40%. Isikulufu se-cavity sidinga ukulungiswa okuncane kunezinye izinhlobo, futhi sifanele imishini yokubumba yomjovo we-cavity eyodwa kanye ne-multi-cavity.

Izinto ezisetshenziswayo zibe sezidlula ekucindezelweni ngaphambi kokufinyelela endaweni yomjovo. Ngemuva kwalokho, ilungele ukujova esikhunjeni, lapho ithatha ukuma komkhiqizo okhiqizwayo.

Isikulufu somucu owodwa sinomzimba omude onobubanzi obungu-20% noma u-30%. Kubhekwa njengesinye sezikulufu ezihamba phambili zokubumba umjovo wepulasitiki ngoba kunikeza ukugeleza okufanele futhi sinikeze ukusabalalisa okufanayo kwengcindezi.

I-Conveyor Screw

Isikulufu se-conveyor sifana kakhulu nesikulufu esinomucu owodwa, kodwa sinemicu emibili ehambisanayo exhunywe intambo enganqamuki. Lolu hlobo lwesikulufu lunikeza amazinga aphansi okugunda futhi lubhangqwa kangcono nemishini ekhiqiza ama-resin asezingeni eliphezulu lokushisa anomthamo othize ongu-0.8 noma ngaphezulu.

Lesi sitayela sesikulufu somjovo sinomzimba oqondile onemifantu ezungeza bonke ubude besikulufu. Lolu hlobo lwesikulufu lunemicu emibili noma ngaphezulu futhi luvame ukusetshenziswa nezikulufu zokudlulisa nezinye izinhlobo zezikulufu zokujova ukuze kuthuthukiswe ukugeleza nokusabalalisa ingcindezi.

Isikulufu esizungezisa uhlangothi sifaka intambo eyodwa eqhubekayo engenazo izintambo ezinganqamuki, ama-grooves, noma insiza.

Izikulufo zeRam

Izikulufu ze-ram zikhiqiza ingcindezi ephezulu yomjovo kanye namazinga okugunda, okuzenza zilungele izinto ezikhiqiza izingxenye eziwugqinsi namayunithi okubamba.

Lolu hlobo lwesikulufu lubonakala ngesilinganiso esikhulu sobude ukuya kububanzi futhi azikho izintambo ezinganqamuki. Lesi sitayela sesikulufu silandela ukushaywa kwenqama futhi ngokuvamile sisetshenziswa ngezikulufu zokudlulisa noma ezinye izinhlobo zezikulufu zokujova.

Izikulufa ezijikelezayo

Isikulufu esijikelezayo sinendlela yethuluzi elizungezayo eliqhubekayo futhi sisetshenziswa ezinhlelweni zokususa izinto. Lolu hlobo lwesikulufu luphinde lube nesilinganiso esikhulu sobude ukuya kububanzi. Ngokuvamile isetshenziswa ngezikulufu zokudlulisa noma ezinye izinhlobo zezikulufu zokujova kodwa ingaxhunywa kuyunithi yokushayela ezimele ukuze isetshenziswe njengomshini ozimele.

Isiphetho

Ngakho-ke, yiziphi izikulufu zokujova ezingcono kakhulu zokubumba umjovo wepulasitiki? Incike ngempela kuhlelo lwakho lokusebenza oluthile. Kodwa-ke, izikulufu ezijikelezayo zinikeza ukulawula okukhulayo nokucindezela kwe-vacuum; ngakolunye uhlangothi, imiklamo yesikulufu ephindaphindayo yakhelwe ukuphumela okuphezulu kanye nezingcindezi zokujova eziphansi. Yize ingekho into efana nesikulufu esiphelele sezinhlelo zokusebenza zokubumba umjovo wepulasitiki, ukuthola esiseduze ngokwanele kungaba umehluko phakathi kwamazinga asheshayo, anenzuzo kanye nesivinini sokukhiqiza esinensayo kakhulu.
