1. Inkcazo yeisitofu sokungunda
Umngundo osetyenziselwa ukubumba inaliti yeplastiki ibizwa ngokuba yinaliti yokubumba, okanye isitofu sokubumba ngokufutshane.Isitofu sokubumba sinokubumba iimveliso zeplastiki ezinemilo enzima, ubukhulu obuchanekileyo okanye ukufakwa ngexesha elinye.
"Iinxalenye ezisixhenxe zokubumba, iinxalenye ezintathu zenkqubo".Ukubumba isitofu, umatshini wokubumba kunye nenaliti unempembelelo enkulu kumgangatho weemveliso ezibunjiweyo, kwaye kunokuthiwa ukuba i-mold idlala indima enkulu kunomatshini wokubumba inaliti;Ekubunjweni kwesitofu, ukuba ukubunjwa akuqondwa ngokupheleleyo, kunzima ukufumana iimveliso ezibunjiweyo ezilungileyo.
2、 Ubume beisitofu sokungunda
Ulwakhiwo lwe-injection mold luchongwa luhlobo lomatshini wokubumba inaliti kunye neempawu zesakhiwo samalungu eplastiki.Isibini ngasinye sokungunda senziwe ngokungunda okushukumayo kunye nokungunda okusisigxina.I-mold ehambayo ifakwe kwi-plate ehambayo yomshini wokubumba umjovo, ngelixa i-mold esisigxina ifakwe kwi-plate ehleliweyo yomshini wokubumba umjovo;Ngethuba lokubunjwa kwenaliti, inkqubo yokutya kunye ne-cavity yenziwa emva kokuba i-mold ehambayo kunye ne-mold fixed ivaliwe.Xa i-mold ihlulwe, inxalenye yeplastiki okanye inxalenye yebhiya ishiywe kwicala le-mold ehambayo, kwaye inxalenye yeplastiki ikhutshwe yi-demoulding mechanism ebekwe kwi-mold ehambayo.Ngokwemisebenzi eyahlukeneyo yecandelo ngalinye kubumba, iseti yesitofu sokungunda inokwahlulwa ibe ngamacandelo alandelayo:
1. Amalungu akhiweyo
Amacandelo anika imilo, ukwakheka kunye nobukhulu kwizinto zokubumba ngokuqhelekileyo ziqulunqwe ngundoqo (i-punch), i-cavity ye-concave mold, i-thread core, ifake, njl.
2. Inkqubo yokungena
Ngumjelo okhokelela iplastiki etyhidiweyo ukusuka kumbhobho wesitofu ukuya kwindawo evaliweyongundoumgodi.Ngokuqhelekileyo iqulunqwe ngumgijimi oyintloko, i-splitter, isango kunye nokutshaja okubandayo kakuhle.
3. Amacandelo esikhokelo
Ukuze kuqinisekiswe ulungelelwaniso oluchanekileyo lokufa okuhambayo kunye nokufa okusisigxina xa zivaliwe, icandelo lesikhokelo limiselwe ukukhokela kunye nesikhundla.Yenziwe ngentsika yesikhokelo kunye nomkhono wesikhokelo.Ezinye iimbumba zisekwa kunye namacandelo esikhokelo kwipleyiti ye-ejector ukuqinisekisa ukuhamba okugudileyo nokuthembekileyo kwendlela yokudiliza.
4. Indlela yokwenza
Izixhobo zokudiliza iinxalenye zeplastiki kunye neenkqubo zokungena zineendlela ezininzi zolwakhiwo.Ezona ndlela zixhaphakileyo zokudiliza ziyi-ejector pin, i-pipe jacking, uphahla kunye ne-pneumatic ejection, ezidityaniswe ngokubanzi ngentonga ye-ejector, intonga yokusetha ngokutsha, i-slingshot, i-ejector rod fixing plate, uphahla (indandatho ephezulu) kunye ne-sleeve yesikhokelo sophahla.
5. Inkqubo yokulawula ubushushu bomngundo
Ukuze kuhlangatyezwane neemfuno zenkqubo yokubumba inaliti kwingundoiqondo lobushushu, iqondo lobushushu lokungunda elawula intonga yokufudumeza iyafuneka ukulungelelanisa ubushushu bokungunda.
6. Inkqubo yokukhupha
Ukuze ukhuphe igesi kwindawo yokubumba ngokufanelekileyo, i-slot yokukhupha isoloko isetwa kwindawo yokwahlula i-mold kunye nendawo efanelekileyo yokufaka.
8. Amanye amalungu olwakhiwo
Ibhekisa kumacandelo amiselweyo ukuhlangabezana neemfuno zesakhiwo sokungunda (ezifana nepleyiti esisigxina, itemplate eshukumayo/esisigxina, ikholamu yenkxaso, ipleyiti yokuxhasa kunye nesikrufu sokudibanisa)
