Intshayelelo kulwazi olusisiseko loyilo lokungunda inaliti

I. Isiseko soyilo

Ukuchaneka komda kunye nokuchaneka kwemilinganiselo ehambelanayo

Ngokweemfuno ezithile kunye nemisebenzi yemveliso yonke yeemveliso zeplastiki ukumisela umgangatho wangaphandle kunye nobukhulu obuthile ukuba loluphi uhlobo: iimveliso zeplastiki ezineemfuno zomgangatho ophezulu wenkangeleko kunye neemfuno zokuchaneka okuphantsi, ezifana namathoyizi;Iimveliso zeplastiki ezisebenzayo, iimfuno ezingqongqo zobukhulu;Iimveliso zePlastiki ezinenkangeleko engqongqo kunye neemfuno zobungakanani, ezinjengeekhamera.

Nokuba i-Angle yokudiliza isengqiqweni.

Ukuthambeka kwe-Demoulding kuhambelana ngokuthe ngqo kwi-demoulding kunye nomgangatho weemveliso zeplastiki, oko kukuthi, ezinxulumene nenkqubo yokutofa, nokuba inaliti inokuqhutywa ngokutyibilikayo: i-slope ye-demoulding yanele;I-slope kufuneka iguqulelwe kwindawo yokwahlula okanye yokuhlukana kweemveliso zeplastiki ekubumbeni;Ingaba iya kuchaphazela ukuchaneka kokubonakala kunye nobukhulu bodonga;

Ingaba iya kuchaphazela amandla enye inxalenye yeemveliso zeplastiki.

2. Iinkqubo zokuyila

Uhlalutyo kunye nokwetyisa imizobo yemveliso yeplastiki kunye nemibutho (iisampulu eziqinileyo):

Ijometri yemveliso;

Imilinganiselo, ukunyamezela kunye nemigangatho yoyilo;

Iimfuno zobugcisa;

Igama leplastiki kunye nenombolo yebhrendi

Iimfuno zomphezulu

Inombolo yomngxuma kunye nokulungiswa komngxuma:

Ubunzima bemveliso kunye nomthamo wenaliti yomatshini wokutofa;

Indawo eqikelelweyo yemveliso kunye ne-clamping force yomatshini wokutofa;

Ubungakanani bangaphandle bokungunda kunye nendawo esebenzayo yokufaka isitofu sokubumba umatshini (okanye umgama phakathi kwentonga yokutsala umatshini wokutofa)

Ukuchaneka kwemveliso, umbala;

Ingaba imveliso ine-side shaft core kunye nendlela yonyango;

Ibhetshi yeemveliso;

Inzuzo yezoqoqosho (ixabiso lemveliso ngokungunda)

Inombolo ye-Cavity yagqitywa, kwaye emva koko kulungiselelo lwe-cavity, ukulungiswa kwendawo yomgodi, ukulungiswa kwe-cavity kubandakanya ubungakanani bokungunda, uyilo lwenkqubo ye-gating, ibhalansi ye-gating system, uyilo lwesilayidi esingundoqo sokutsalwa) amaziko, faka, kunye noyilo londoqo, uyilo lwenkqubo yokutshintshiselana kobushushu, ezi ngxaki kunye nomphezulu wokwahlula kunye nokukhethwa kwendawo yesango, ngoko ke inkqubo yoyilo oluthile, uhlengahlengiso oluyimfuneko kufuneka lwenziwe ukufezekisa uyilo olugqibeleleyo.

3. Ukumiselwa kwendawo yokwahlulahlula

Akukho mpembelelo kwimbonakalo

Ukuqinisekisa ukuchaneka kweemveliso, ukucwangciswa kwesikhunta, ngokukodwa ukulungiswa kwe-cavity;

Ivumela inkqubo yokungena, inkqubo yokukhupha, ukuyila inkqubo yokupholisa;

Ukulungelelaniswa nokuvula ukubumba (ukuhlukana, ukuchithwa) ukuqinisekisa ukuba xa uvula isikhunta, ukwenzela ukuba iimveliso zihlale kwicala elihambayo lokubumba;

Ukuququzelela ilungiselelo lokufakwa kwesinyithi.

4. Uyilo lwenkqubo yokugawula

Uyilo lwenkqubo yokungena lubandakanya ukukhethwa kwejelo eliphambili, imilo kunye nobukhulu becandelo le-shunt, indawo yesango, ifom yesango kunye nobukhulu becandelo lesango.Xa usebenzisa isango lephoyinti, ukwenzela ukuba kuqinisekiswe ukuchithwa kwe-shunt, ingqwalasela kufuneka ihlawulwe kwakhona kuyilo lwesixhobo sesango, isixhobo sokuphosa kunye nomatshini wesango.

Xa uyila inkqubo yokungena, eyokuqala kukukhetha indawo yesango.

Ukukhethwa kwendawo yesango kuhambelana ngokuthe ngqo nomgangatho wokubumba imveliso kunye nenkqubela phambili egudileyo yenkqubo yokutofa.Ukukhetha indawo yesango kufuneka kulandele le migaqo ilandelayo:

Indawo yesango kufuneka ikhethwe kwindawo yokuhlukana ngokusemandleni ukwenzela ukuba kube lula ukucocwa kwesango ngexesha lokucubungula kunye nokusetyenziswa kwesikhunta;

Umgama phakathi kwendawo yesango kunye nenxalenye nganye yecavity kufuneka ihambelane kangangoko kunokwenzeka, kwaye wenze inkqubo ibe yifutshane;

Indawo yesango kufuneka iqinisekise ukuba xa iplastiki ingena emgodini, i-cavity ibanzi kwaye inzima, ukwenzela ukuba kube lula ukuhamba kakuhle kweplastiki;

Indawo yesango kufuneka ivulwe kwindawo engqindilili yamacandelo eplastiki;

Gwema iplastiki kwi-flow down the cavity ngqo kwi-cavity wall, i-core okanye ifake, ukwenzela ukuba iplastiki ikwazi ukungena kwi-cavity ngokukhawuleza, kwaye ugweme i-core okanye ifake i-deformation;

Ngokusemandleni ukuphepha uphawu lwe-welding yemveliso, okanye ukwenza uphawu lwe-welding kwimveliso alukho iindawo ezibalulekileyo;

Indawo yesango kunye nesalathiso sokungena kweplastiki kufuneka yenze iplastiki iqhube kwi-cavity ngokulinganayo kunye nolwalathiso oluhambelanayo lwe-cavity, kwaye iququzelele ukukhutshwa kwegesi emgodini;

Isango kufuneka libekwe kwinxalenye yemveliso elula ukuyisusa, ngelixa ingachaphazeli ukubonakala kwemveliso kangangoko kunokwenzeka.
