Isitofu ngumgaqo wokusebenza kunye nesakhiwo yintoni?
Isitofu sokungunda yinxalenye ebalulekileyo yenkqubo yokubumba isitofu, kwaye indima yayo kukutofa izinto zeplastiki kwimeko etyhidiweyo ibe ngumbumba ukwenza iindawo zokubumba ezifunekayo.I-injection mold inesakhiwo esiyinkimbinkimbi kunye neqondo eliphezulu leemfuno zenkqubo echanekileyo, ngoko kubaluleke kakhulu ukuqonda umgaqo wayo wokusebenza kunye nesakhiwo, makhe sijonge ngokubanzi.

Okokuqala, uthetha ntoni umgaqo wokusebenza kwesitofu sokungunda

Isitofu sokungunda sahlulwe ngamanyathelo amabini kwinkqubo yokusebenza: ukuzaliswa kunye nokunyanga.Kwinqanaba lokuzalisa, inkqubo yokubumba i-injection ye-mold ifaka izinto zeplastiki ezityhidiweyo ukusuka kumatshini wokubumba umjovo kwi-mold ngokusebenzisa i-pre-set pressure and flow rate ukufezekisa injongo yokuzalisa i-mold cavity.Ngethuba lesigaba sokunyanga, izinto zeplastiki eziza kujojowa ngokukhawuleza zipholile ngaphakathi kwi-mold kwaye ziqiniswe kwindawo edibeneyo.Ngeli xesha, i-mold ivuliwe kwaye inxalenye ebunjiweyo ityhilwa ngaphandle kwe-mold ukugqiba yonke inkqubo yokubumba inaliti.

Okwesibini, sithetha ntoni ukwakheka kwesitofu sokubumba

Ubume be-injection mold bubandakanya inkqubo yokubumba i-injection, i-mold structure, inkqubo yokupholisa kunye nenkqubo yokukhupha, njl.

(1) Inkqubo yokubumba isitofu:

Ibhekisa kwinxalenye yoqhagamshelo phakathi komatshini wokubumba kunye nenaliti yokubumba, apho impahla yeplastiki etyhidiweyo kumatshini wokubumba i-injection ithuthelwa kwi-mold ukuqonda ukubunjwa kwamalungu.Inkqubo ibandakanya amacandelo afana nemilomo, iibhakethi ezinyibilikayo kunye neebhakethi zokugcina.

(2) Ulwakhiwo lokungunda:

Ibhekisa kwimilo yangaphakathi kunye nesakhiwo somngundo, kubandakanywa i-mold cavity, itemplate, i-billet kunye nesithuba sesikhokelo.Uyilo kunye nokuveliswa kokubumba kwesitofu kuxhomekeke kwiimfuno zeemveliso ezibunjiweyo kunye neempawu zemilo kunye nobukhulu bamalungu, ngoko ke imiba emininzi kufuneka ithathelwe ingqalelo kwinkqubo yoyilo.

(3) Inkqubo yokupholisa:

Ibhekisela kumjelo wokupholisa we-mold, osetyenziselwa ukupholisa ngokukhawuleza isikhunta emva kokuzaliswa kunye nokuvumela ukuba izinto zeplastiki eziqiniweyo zibe nzima kwaye zenziwe.Inkqubo yokupholisa ibandakanya imibhobho yamanzi okupholisa, imingxuma yokupholisa, iitanki zamanzi zokupholisa kunye namanye amacandelo, kunye noyilo kunye nokulungiswa kwayo kuxhomekeke kubukhulu kunye nokuma kweendawo ezibunjiweyo, kunye neemfuno zokusebenza kakuhle kwemveliso.

(4) Inkqubo yokukhupha umoya:

Ibhekisela kwinkqubo esetyenziselwa ukususa iigesi ezinobungozi ezifana nomoya kunye nomphunga wamanzi, obalulekileyo kwinkqubo yokubumba inaliti.Ukuba ezi gesi azipheli ngexesha, kuya kuba nefuthe elibi kwiisitofu sokubumbaizinto eziphathekayo, ezifana nokubangela amaqamza, imingxunya eshwabeneyo njalo njalo.

Ukushwankathela, ukuqonda umgaqo wokusebenza kunye nolwakhiwo lwesitofu sokungunda kubalulekile ekwandiseni inkqubo yokubumba inaliti kunye nokuphucula umgangatho weemveliso ezigqityiweyo.Kuphela ngokukwazi kakuhle ezi ngqikelelo zisisiseko kunye neendlela zenkqubo sinokuthi sifezekise ngcono umgangatho kunye nemveliso esebenzayo yeemveliso ezibunjiweyo.
