Nhanganyaya kune ruzivo rwekutanga rwejekiseni mold dhizaini

I. Dhizaini hwaro

Dimensional kurongeka uye kurongeka kwezviyero zvine hukama

Zvinoenderana nezvinodiwa chaizvo uye mabasa echigadzirwa chose chezvigadzirwa zvepurasitiki kuona mhando yekunze uye saizi chaiyo ndeyerudzii: zvigadzirwa zvepurasitiki zvine chimiro chepamusoro zvinodiwa uye yakaderera dimensional kurongeka zvinodiwa, sematoyi; Zvishandiso zvepurasitiki zvinoshanda, zvakaomesesa saizi zvinodiwa; Zvigadzirwa zvepurasitiki zvine chitarisiko chakasimba uye saizi zvinodiwa, semakamera.

Kunyangwe iyo Demoulding Angle inonzwisisika.

Demoulding slope yakanangana neiyo demoulding uye mhando yezvigadzirwa zvepurasitiki, kureva, zvine chekuita nejekiseni, kana jekiseni rinogona kuitwa zvakanaka: demoulding slope yakakwana; Iyo yakatsetseka inofanirwa kuchinjirwa kune yekuparadzanisa kana kupatsanura pamusoro pezvigadzirwa zvepurasitiki mukuumba; Kunyangwe zvichakanganisa kurongeka kwechitarisiko uye saizi yemadziro;

Kunyangwe zvichakanganisa kusimba kwechimwe chikamu chezvigadzirwa zvepurasitiki.

2. Maitiro ekugadzira

Ongororo uye kugaya kwepurasitiki chigadzirwa kudhirowa uye masangano (yakasimba samples):

Iyo geometry yechigadzirwa;

Zviyero, kushivirira uye zviyero zvekugadzira;

Technical zvinodiwa;

Zita repurasitiki uye nhamba yemhando

Zvinodiwa zvepamusoro

Cavity nhamba uye cavity kuronga:

Chigadzirwa uremu uye jekiseni vhoriyamu yemuchina wejekiseni;

Nzvimbo yakarongedzerwa yechigadzirwa uye iyo clamping simba yemushini wejekiseni;

Mold yekunze dimension uye inoshanda yejekiseni muchina wekumisa mold (kana chinhambwe mukati mekudhonza tsvimbo yemushini wejekiseni)

Kururama kwechigadzirwa, ruvara;

Kunyangwe chigadzirwa chine padivi shaft musimboti uye nzira yayo yekurapa;

Kugadzira batch yezvigadzirwa;

Kubatsirwa kwehupfumi (kukosha kwekugadzira pa mold)

Cavity nhamba yakatemerwa, uyezve kurongeka kwegomba, kurongeka kwegomba, kurongeka kwegomba kunosanganisira saizi yekuumbwa, dhizaini yegating system, chiyero chegating system, dhizaini yepakati-inodhonza slider) masangano, isa, uye dhizaini yepakati, dhizaini yekutsinhana kwekupisa, matambudziko aya uye nzvimbo yekuparadzanisa uye kusarudzwa kwenzvimbo yegedhi, saka iyo chaiyo dhizaini dhizaini, Zvinodiwa zvinogadziriswa zvinofanirwa kuitwa kuti zvibudirire zvakanyanya dhizaini.

3. Kutsunga kwenzvimbo yekuparadzana

Hapana kukanganisa pachitarisiko

Kuve nechokwadi chechokwadi chezvigadzirwa, mold processing, kunyanya iyo cavity processing;

Inobatsira kune gating system, exhaust system, kutonhora system dhizaini;

Inokodzera kuvhurika kuvhurika (kuparadzanisa, kudhirowa) kuve nechokwadi chekuti kana uchivhura mold, kuitira kuti zvigadzirwa zvirambe zviri mudivi rekufamba;

Ita kuti kurongeka kwesimbi inopinza.

4. Gating system design

Iyo gating system dhizaini inosanganisira kusarudzwa kwechiteshi chikuru, chimiro uye ukuru hwechikamu cheshunt, nzvimbo yegedhi, chimiro chegedhi uye ukuru hwechikamu chegedhi. Paunenge uchishandisa gedhi rekunongedza, kuitira kuti uve nechokwadi chekudururwa kweshunt, kutarisisa kunofanirwa kubhadharwa kune dhizaini yegedhi mudziyo, iyo yekukanda mudziyo uye gedhi maitiro.

Paunenge uchigadzira gating system, yekutanga ndeyekusarudza nzvimbo yegedhi.

Kusarudzwa kwenzvimbo yegedhi kwakanangana nemhando yekugadzirwa kwechigadzirwa uye kufambira mberi kwakatsetseka kwekuita jekiseni. Kusarudzwa kwenzvimbo yegedhi kunofanirwa kutevedzera zvinotevera misimboti:

Nzvimbo yegedhi inofanira kusarudzwa panzvimbo yekuparadzanisa sezvinobvira kuitira kuti zvive nyore kucheneswa kwegedhi panguva yekugadzira mold uye kushandiswa;

Chinhambwe pakati pechinzvimbo chegedhi uye chikamu chimwe nechimwe chegomba chinofanira kuenderana kusvika pazvinobvira, uye kuita kuti nzira yacho ive pfupi;

Nzvimbo yegedhi inofanirwa kuve nechokwadi chekuti kana ipurasitiki ichipinda mugomba, gomba rakafara uye gobvu, kuitira kuti kufambisa kuyerera kwepurasitiki;

Nzvimbo yegedhi inofanira kuvhurwa pane chikamu chakakora chezvikamu zvepurasitiki;

Dzivisa purasitiki mukuyerera ichidzika negomba rakananga mumadziro emukati, musimboti kana kuisa, kuitira kuti ipurasitiki inogona kuyerera ichipinda mugomba nekukasira, uye kudzivirira musimboti kana kuisa deformation;

Sezvingabvira kudzivirira chigadzirwa welding mucherechedzo, kana kuita welding mucherechedzo mune chigadzirwa haisi zvikamu zvinokosha;

Nzvimbo yegedhi uye nzira yekupinda mukati mepurasitiki inofanira kuita kuti plastiki ipinde mugomba zvakaenzana pamwe chete negwara rakafanana regomba, uye kufambisa kubuda kwegesi mumhango;

Gedhi rinofanira kuiswa pachikamu chechigadzirwa chiri nyore kubvisa, asi chisingakanganisi kutaridzika kwechigadzirwa zvakanyanya sezvinobvira.
