Plastic mold ine simba rakakosha pakugadzirisa zvigadzirwa zvepurasitiki.Uye dhizaini yedhizaini uye huwandu hwekugadzira hunoratidzawo danho remaindasitiri emunyika, mumakore achangopfuura kuvandudzwa kwekugadzirwa kwepurasitiki yekuumba mold uye nhanho yakakurumidza kukurumidza, kushanda kwakanyanya, otomatiki, hukuru, huchokwadi, hupenyu hurefu hwehupfu pasi pe chikamu chakawedzera kukura kubva pakugadzira mold, nzira dzekugadzirisa, kugadzirisa michina, kurapwa kwepamusoro uye nezvimwe zvinhu zvakati wandei kupfupisa mamiriro ekukura kwe mold.
Plastic molding nzira uye mold design
Gasi rinobatsira kuumba, gasi rinobatsira kuumba haisi teknolojia itsva, asi mumakore achangopfuura, yakakurumidza kukurumidza uye dzimwe nzira itsva dzakabuda.Liquefied gasi rinobatsirwa jekiseni ndere kubaya rudzi rwe preheated yakakosha vaporize liquid mupurasitiki inonyunguduka kubva mujekiseni.Iyo mvura inopisa uye inonyungudutswa mumhango ye mold kuti iwedzere, ichiita kuti ive mhango, uye kusundira iyo inonyungudika kusvika pamusoro pegomba re mold.Iyi nzira inogona kushandiswa kune chero thermoplastic plastiki.Vibration gasi rinobatsira jekiseni ndeyekushandisa vibration simba kune epurasitiki kunyunguduka kuburikidza neyakamanikidzwa gasi yechigadzirwa chinopisa, kuitira kudzora micro-chimiro chechigadzirwa uye kugadzirisa mashandiro echigadzirwa.Vamwe vagadziri vanoshandura gasi rinoshandiswa mugasi rinobatsira kuumba kuita zvigadzirwa zvitete, uye vanogona zvakare kugadzira mahombe maburi zvigadzirwa zvine mhando yepamusoro uye yakaderera mutengo, asi yakakosha kudonha kwemvura.
Sunda uye dhonza mold mold, maviri kana anopfuura machani akaiswa akatenderedza mold cavity uye akabatana neaviri kana anopfuura majekiseni emidziyo kana mapiston anodzorera.Mushure mekunge jekiseni rapera, sikuruu kana piston yemudziyo wejekiseni inofamba ichienda mberi nekumashure kusunda nekukweva kunyungudika mumhango yekunyungudika isati yanyungudika.Iyi tekinoroji inodaidzwa kuti dynamic pressure kuchengetedza tekinoroji, inovavarira kudzivirira dambudziko rekukura kukuru kana zvigadzirwa zvakakora zvaumbwa nemaitiro echinyakare ekuumba, High pressure ichigadzira matete magoko.Zvigadzirwa zvakatetepa zvinogadzirwa kazhinji zvigadzirwa zvine reshiyo refu yekuyerera.Vazhinji vavo vanoshandisa multi-point gedhi molds.Nekudaro, kudururira-mapoinzi akawanda kunokonzeresa welding seams, izvo zvinozokanganisa maitiro ekuona ezvimwe zvinhu zvinoonekera.Single point kudurura haisi nyore kuzadza mold cavity, saka vanogona kuumbwa nehigh pressure yekugadzira tekinoroji.Semuenzaniso, iyo US Air Force, F16 fighter cockpit inogadzirwa neiyi tekinoroji, iyo yakashandiswa kugadzira PC mota yemhepo windscreens, Iyo jekiseni yekumanikidza yekuumbwa kwepamusoro-soro inowanzopfuura 200MPA, saka iyo mold zvinhu inofanirawo kusarudza simba rakawanda. uye kuoma nepamusoro Young's modulus.Chinokosha chekuumbwa kwepamusoro-soro ndiko kutonga kwekushisa kwe mold.Mukuwedzera, teerera kune yakapfava kupera kwe mold cavity.Zvikasadaro, ipurasitiki ichapiswa nekuda kwekuneta kwakashata kunokonzerwa nejekiseni rekukurumidza.
