14. Gogewa (mutuwar ceto)
Mold polishing shine don aiwatar da rami na ƙirƙira da ainihin gamawa zuwa buƙatun samfurin.Yana da muhimmin ɓangare na tsarin masana'anta.Ingancin daidaiton gogewa yana shafar ingancin bayyanar samfur kai tsaye.Akwai hanyoyi da yawa na goge goge, kamar gyaran injin (ultrasonic), gogewar injin niƙa da goge goge da hannu.Mafi yawan amfani da goge goge na hannu a ƙarƙashin sharuɗɗa na gabaɗaya, tsarinsa yana buƙatar:
(1) Lokacin gogewa da adana gyare-gyare, dole ne ka gani da fahimtar buƙatun ciki da waje na samfurin.
(2) Kafin goge goge, yi amfani da fayil don datsa alamun saman da aka bari ta hanyar sarrafawa daban-daban.
(3) Dangane da datsa tare da dutsen ƙanƙara, yi amfani da takarda yashi daga m zuwa tarar don adana haske bisa ga buƙatun samfur.
(4) Don samfuran da ke da buƙatu na musamman, kamar sassa na zahiri, dole ne a goge su da manna abrasive.
(5) Kayan aikin da aka goge dole ne ya sami layi mai haske, mai haske da santsi, kuma babu sasanninta mai zagaye a jaws.
15. Tare da gwangwani
Za a huda firam ɗin da ke ƙasa da farantin allurar fuska ta cikin ramin fil ɗin da ke ƙasan mold na ciki, sannan a niƙa rami fil ɗin bututu a ramin thimble akan farantin allurar fuska, sannan a saka fil ɗin ejector a cikin farantin allurar fuska, ƙasan. mold frame da ƙananan ciki mold.Tabbatar cewa fil ɗin ejector yana jujjuya tare da madaidaicin ƙirar ciki na sama, sa'an nan kuma shigar da fil ɗin ejector a gefen ramin ejector fil na farantin fuska, sa'annan a matse fil ɗin a wuri.
16. Yanayin gwaji
(1), sanye take da na'urorin haɗi irin su jikin takobi, da kuma haɗa nau'in.
(2) Shigar da mold akan na'urar giya bisa ga tsarin aikin injin giya don aiwatar da sassan giya.Gwajin mold wani muhimmin sashi ne na tsarin gyare-gyare.Domin daidai ƙayyade ingancin mold a cikin nau'i na giya sassa, da clamping matsa lamba, allura matsa lamba, lantarki dumama zafin jiki, narkewa tanderun zafin jiki, da dai sauransu dole ne a gyara kafin mold gwajin, kuma kowane lokaci.Yi rikodin gwaji.Kayan aikin don gwajin giya dole ne ya kasance ba shi da ƙwanƙolin sanyi, babu gaban gaba, babu raguwa, kumfa a cikin 15%, babu bayyanannun jaws da alamun ruwa, kuma saman yana santsi kuma ƙirar ta kasance santsi.Idan ya kasa cika buƙatun, ya zama dole a gyara kuma a sake gwadawa.
17. Gyara
Bisa ga sakamakon gwajin, an gyara mold, kuma an gyara samfurin bisa ga bukatun abokin ciniki da bukatun taro.Gyaran gyaggyarawa wani muhimmin sashi ne na masana'anta.Manufar masana'anta mold shine samar da taro.Gudun da daidaito na gyare-gyaren gyare-gyare kai tsaye suna shafar ingancin samfur da ci gaban samarwa.Ayyukan canza mold shine tabbatar da cewa sa hannu (ofishin tallace-tallace) ya taru ba tare da kayan aikin taimako don daidaitawa daidaitawa ya sadu da kasuwa (abokin ciniki) da buƙatun akwatin girgiza (sai dai buƙatun kayan ado na saman).Za a aika da ofishin shigarwa na injiniya zuwa ofishin abokin ciniki bayan nazari na ciki.Dangane da matsalar ƙirar da kanta, injiniyan injiniyan zai samar da bayanan gyaran gyare-gyare bisa ga buƙatun taro da buƙatun abokin ciniki.Dole ne a rubuta kayan gyare-gyare a fili kuma harshen yana da sauƙin fahimta kuma ba tare da shubuha ba.Bukatun bayanan dole ne su kasance a bayyane kuma cikakke, dole ne a sanya alamar maƙasudin ga waɗanda ke da buƙatun matsayi na gaba da na baya, kuma dole ne a yi adadi ga waɗanda ke da buƙatun sifa.Lokacin da injiniyan ya ƙaddamar da bayanin gyaran gyare-gyare ga ma'aikatan gyaran gyaran gyare-gyare, dole ne ya bayyana a fili ainihin mahimman abubuwan gyaran gyaran gyare-gyaren, sassan da za a gyara, abubuwan da ake bukata don gyarawa, da kuma manufar gyarawa.Bayan yanke shawara na mutum, ana iya aiwatar da shi bisa ga mafi kyau.
18. Sakin mold
Bayan an gyaggyara ƙirar, an gwada, sanya hannu, kuma ingancin ya cika cikakkiyar buƙatun abokin ciniki da buƙatun taron kayan wasan yara, ana iya ba da ƙirar kuma a saka shi cikin samarwa.
