Kodi mfundo yogwirira ntchito ya nkhungu yothamanga ndi yotani?

Hot Runner mold ndi mapangidwe apamwamba kwambiri omwe mfundo zake zogwirira ntchito zimadalira kuwongolera kutentha komanso kutuluka kwa pulasitiki wosungunuka mosalekeza.

Zotsatirazi ndi zinthu zisanu zofotokozera mwatsatanetsatane mfundo yogwirira ntchito ya hot runner mold:

1. Kutentha dongosolo

Pachimake cha nkhungu yothamanga yotentha ndi njira yotenthetsera, yomwe nthawi zambiri imakhala ndi mphete yamagetsi yamagetsi, chinthu chowotcha komanso chowongolera kutentha.Chowotcha chamagetsi chamagetsi kapena chinthu chotenthetsera chimayikidwa mu mbale yamoto yothamanga kapena diverter mbale kuti ipereke kutentha kofanana ku pulasitiki, kuwonetsetsa kuti pulasitiki nthawi zonse imakhala yosungunuka mu wothamanga.Wowongolera kutentha ali ndi udindo woyang'anira ndikuwongolera kutentha kwa makina otenthetsera kuti atsimikizire kuti kutentha kwa pulasitiki kumakhala kokhazikika panthawi ya jekeseni.

2, kutuluka kwa pulasitiki wosungunuka

Panthawi yopangira jakisoni, tinthu tating'onoting'ono tapulasitiki timalowa mu silinda yowotchera kudzera pa hopper ya makina omangira jekeseni ndikupita patsogolo pansi pa kukankha kwa screw.Pamene tinthu tapulasitiki tikupitiriza kupita patsogolo mkati mwa silinda yowotcherayo, imatenthedwa pang'onopang'ono mpaka kusungunuka.Pulasitiki yosungunukayo imalowa mu nkhungu kudzera mu makina othamanga otentha.

3, jekeseni ndi kuumba

Pambuyo pa pulasitiki yosungunuka yodzaza ndi nkhungu, makina opangira jekeseni amagwiritsira ntchito mphamvu kuti atsimikizire kuti pulasitiki yadzaza mu ngodya iliyonse ya nkhungu.Kenako nkhunguyo imazizidwa kuti pulasitiki yosungunukayo ikhale yolimba ndi kupanga.Chidacho chikazizira mokwanira, nkhungu imatseguka ndipo makina ojambulira amachotsa chinthucho mu nkhungu.

4, jekeseni mosalekeza ndi kulamulira kutentha

Mosiyana ndi nkhungu zachikhalidwe zothamanga zozizira, nkhungu zothamanga zotentha zimatha kusunga pulasitiki mu othamanga mumkhalidwe wosungunuka nthawi zonse, motero amapeza jekeseni mosalekeza.Izi zimachepetsa kwambiri zinyalala za mutu wa zinthu ndikuwongolera magwiridwe antchito.Nthawi yomweyo, chifukwa pulasitiki nthawi zonse imakhala yosungunuka mumsewu woyenda, kuzungulira kwa mankhwalawa kumafupikitsidwa.

5. Kutentha kwa kutentha ndi kulamulira khalidwe

Chinthu china chofunikira cha nkhungu yothamanga yotentha ndi kutentha kwake.Kupyolera mu kuwongolera kolondola kwa kutentha, ndizotheka kuonetsetsa kuti kusinthasintha kwa kutentha kwa pulasitiki yosungunuka mumayendedwe oyenda kumakhala kochepa kwambiri, motero kuonetsetsa kulondola kwazithunzi ndi kukhazikika kwa khalidwe la mankhwala.

6. Mwachidule

Mfundo yogwirira ntchito ya nkhungu yothamanga yotentha makamaka imadalira makina otenthetsera ndi kutuluka kosalekeza kwa pulasitiki yosungunuka.Kupyolera mu ndondomeko yolondola ya kutentha ndi jekeseni, nkhungu zothamanga zotentha zimathandiza kupanga zinthu zabwino komanso zapamwamba kwambiri.Panthawi imodzimodziyo, zizindikiro za jekeseni mosalekeza ndi kuchepetsa zinyalala zamutu zimachepetsanso mtengo wopanga.
