The zikuchokera nkhungu patsekeke ndi ntchito jekeseni nkhungu

Gawo:

1.Gating system imatanthawuza njira yoyendetsera pulasitiki mu nkhungu kuchokera pamphuno ya makina opangira jekeseni kupita kumimba. Njira zotsatsira wamba zimapangidwa ndi njira zazikulu, ngalande zothamanga, zipata, mabowo ozizira, ndi zina.

2.Lateral parting ndi core kukoka makina.

3.Njira yowongolera mu nkhungu ya pulasitiki makamaka imakhala ndi ntchito zoyika, kutsogolera, ndi kunyamula kupanikizika kwina kwa mbali kuti zitsimikizire kutseka kolondola kwa nkhungu zosuntha ndi zokhazikika. Makina owongolera nkhungu amakhala ndi zolembera, manja owongolera kapena mabowo owongolera (otsegulidwa mwachindunji pa template), ma cones, ndi zina.

4. Chipangizo cha ejection makamaka chimagwira ntchito yotulutsa ntchito kuchokera ku nkhungu, ndipo imapangidwa ndi ndodo ya ejector kapena chubu cha ejector kapena mbale yokankhira, mbale ya ejector, ejector fixed plate, ndodo yobwezeretsanso, ndi ndodo yokoka.

5. Kuzizira ndi kutenthetsa dongosolo.

6. Dongosolo la utsi.

7. Zigawo zoumbidwa zimatanthawuza mbali zomwe zimapanga nkhungu. Makamaka kuphatikiza: nkhonya nkhungu, concave nkhungu, pachimake, kupanga ndodo, kupanga mphete ndi amaika ndi mbali zina.

jekeseni zisamere nkhungu zimagawidwa mu thermosetting pulasitiki nkhungu ndi thermoplastic pulasitiki nkhungu malinga akamaumba makhalidwe; malinga ndi ndondomeko akamaumba, iwo anawagawa mu stamping nkhungu tooling, kutengerapo nkhungu, kuwomba nkhungu, nkhungu kuponyedwa, nkhungu thermoforming, ndi otentha kukanikiza nkhungu, jekeseni nkhungu, etc.

Zinthu za nkhungu zimakhudza mwachindunji kuzizira. Zomwe zimagwiritsidwa ntchito popanga nkhungu zimaphatikizapo P20 zitsulo, H13 zitsulo, P6 zitsulo, S7 zitsulo, beryllium copper alloy, aluminiyamu, 420 zitsulo zosapanga dzimbiri, ndi 414 zosapanga dzimbiri.

Mphepete mwa nkhungu ndi malo omwe ali ndi mawonekedwe ofanana ndi mankhwala opangidwa omwe amasiyidwa mu nkhungu kuti agwirizane ndi pulasitiki yosungunuka ndi kupanga mankhwala pambuyo pogwira ndi kuziziritsa. Danga limeneli limatchedwanso nkhungu. Nthawi zambiri zinthu zing'onozing'ono zomalizidwa zimapangidwira ngati "machubu amitundu yambiri" chifukwa chachuma komanso kuchita bwino. Mwachitsanzo, nkhungu imakhala ndi mazenera angapo ofanana kapena ofanana kuti apange mwachangu.

Ngongole yokonzekera:

Ngongole yofananira yojambula ili mkati mwa 1 mpaka 2 madigiri (1/30 mpaka 1/60). Kuzama ndi pafupifupi madigiri 1.5 kwa 50 mpaka 100 mm, ndi pafupifupi 1 digiri kwa 100 mm. Nthiti siziyenera kukhala zosachepera madigiri 0,5 ndipo makulidwe ake sayenera kuchepera 1 mm kuti athandizire kupanga nkhungu ndikuwonjezera moyo wa nkhungu.

Mukakumana ndi kufunikira kwa kapangidwe kake, tikulimbikitsidwa kuti ngodyayo ikhale yayikulu kuposa momwe zimakhalira. Ngodya yoperekedwa ndi iyo ikuyenera kukhala yopitilira madigiri 2, koma ngodyayo isapitirire madigiri 5.

Basic style:

Chophimba cha mbale ziwiri ndi mtundu wa nkhungu womwe umagwiritsidwa ntchito kwambiri ndipo uli ndi ubwino wa mtengo wotsika, kapangidwe kosavuta komanso kachipangizo kakang'ono.

Dongosolo lothamanga la nkhungu ya mbale zitatu ili pazitsulo zakuthupi. Pamene nkhungu imatsegulidwa, mbale yakuthupi imatulutsa zinyalala mu wothamanga ndi bushing. Mu nkhungu ya mbale zitatu, wothamanga ndi mankhwala omalizidwa adzatulutsidwa mosiyana.

Mitundu yodziwika bwino:

Stamping nkhungu tooling ndi njira yapadera zida ntchito pokonza zinthu mu zigawo ozizira masitampu processing. Amatchedwa ozizira stamping kufa. Kupondaponda ndi njira yopondereza yomwe imagwiritsa ntchito nkhungu yomwe imayikidwa pa makina osindikizira kuti igwiritse ntchito kupanikizika kwa zinthuzo kutentha kutentha kuti ipangitse kupatukana kapena kupunduka kwa pulasitiki kuti apeze zigawo zofunika.
