1, Tsanangudzo yejekiseni muforoma
Chiumbwa chinoshandiswa pakuumba mapurasitiki chinonzi injection mold, kana kuti injection mold muchidimbu. Chiumbwa ichi chinogona kugadzira zvigadzirwa zvepurasitiki zvine chimiro chakaoma, saizi chaiyo kana kuti zvinhu zvinoiswa panguva imwe chete.
"Chikamu chinomwe cheforoma, zvikamu zvitatu zvinoitwa". Pakuumba nejekiseni, muchina wekuumba nejekiseni une simba guru pamhando yezvigadzirwa zvakaumbwa, uye zvinogona kutaurwa kuti chiumbwa chine basa guru kupfuura muchina wekuumba nejekiseni; Mukuumba nejekiseni, kana chiumbwa chisina kunzwisiswa zvizere, zvakaoma kuwana zvigadzirwa zvakanaka zvakaumbwa.
2, Maumbirwo ejekiseni muforoma
Maumbirwo eforoma yejekiseni anoenderana nerudzi rwemuchina wekugadzira jekiseni uye hunhu hwezvikamu zvepurasitiki. Peya imwe neimwe yeforoma inoumbwa neforoma yekufambisa uye foroma yakasimbiswa. Foroma yekufambisa inoiswa paplate yekufambisa yemuchina wekugadzira jekiseni, nepo foroma yakasimbiswa inoiswa paplate yakasimbiswa yemuchina wekugadzira jekiseni; Munguva yekuumba jekiseni, sisitimu yekudya uye gomba zvinoumbwa mushure mekunge foroma yekufambisa uye foroma yakasimbiswa yavharwa. Kana foroma yaparadzaniswa, chikamu chepurasitiki kana chikamu chedoro chinosara padivi peforoma yekufambisa, uye chikamu chepurasitiki chinoburitswa ne demoulding mechanism yakaiswa muforoma yekufambisa. Zvichienderana nemabasa akasiyana echikamu chimwe nechimwe muforoma, seti yeforoma yekuisa jekiseni inogona kukamurwa muzvikamu zvinotevera:
1. Zvikamu zvakagadzirwa
Zvikamu zvinopa chimiro, chimiro uye saizi yezvinhu zvekuumba zvinowanzo umbwa nepakati (punch), mhango ye concave mold, pakati pe thread, insert, nezvimwewo.
2. Sisitimu yekuvhara mageti
Ndiyo nzira inotungamira purasitiki yakanyungudutswa kubva pamuromo wejekiseni kuenda kumuromo wakavharwa.chakuvhuvhugomba. Kazhinji rinoumbwa nechinhu chikuru chinotanga kumhanya, chinoparadzanisa, gedhi uye tsime rinochaja rinotonhora.
3. Zvikamu zvekutungamira
Kuti ive nechokwadi chekuti die iri kufamba uye die yakagadzika yakarongeka zvakanaka kana yavharwa, chikamu chegwara chinoiswa panzvimbo yegwara uye nzvimbo. Chinoumbwa nepillar yegwara uye sleeve yegwara. Mamwe mapundu akaiswawo nezvikamu zvegwara pa ejector plate kuti ive nechokwadi chekuti kufamba kwe demoulding mechanism kwakanyatsonaka uye kwakavimbika.
4. Nzira yekubvisa zvinhu
Midziyo yekubvisa zvikamu zvepurasitiki uye masisitimu ekuvhara mageti ine maumbirwo akasiyana-siyana. Nzira dzinonyanya kushandiswa dzekubvisa mageti i ejector pin, pipe jacking, denga uye pneumatic ejection, izvo zvinowanzo gadzirwa ne ejector rod, reset rod, slingshot, ejector rod fixing plate, denga (top ring) uye roof guide post/sleeve.
5. Sisitimu yekudzora tembiricha yemould
Kuti zvizadzise zvinodiwa nemaitiro ekuumba jekiseni pachakuvhuvhutembiricha, chidziyo chekupisa chinodzora tembiricha yeforoma chinodiwa kuti chigadzirise tembiricha yeforoma.
6. Sisitimu yekuburitsa hutsi
Kuti gasi ribudiswe zvakanaka mugomba remuchina wekugadzira mold, panowanzoiswa nzvimbo yekubuda mweya panzvimbo yekuparadzanisa mold uye panzvimbo yekuiisa.
8. Zvimwe zvikamu zvechivakwa
Inoreva zvikamu zvakaiswa kuti zvienderane nezvinodiwa zvechimiro chemold (senge fixed plate, movable/fixed template, support column, support plate uye connecting screw)
