Zvinoenderana nenzira dzakasiyana dzezvikamu zvepurasitiki kuumba uye kugadzirisa, inogona kukamurwa muzvikamu zvinotevera:
·Jekiseni mold
Jekiseni mold inonziwo jekiseni mold.Iyo yekuumbwa kweiyo mold inoratidzwa nekuisa iyo yepurasitiki mbishi zvinhu mumudziyo wekudziya wemushini wejekiseni.Plastiki inodziya uye yakanyungudutswa, uye inofambiswa nescrew kana plunger yemuchina wejekiseni, inopinda mugomba rekuumbwa kuburikidza nenozzle uye gating system ye mold, uye purasitiki inoumbwa mugomba rekuumbwa kuburikidza nekuchengetedza kupisa, kumanikidza kuchengetedza. , kutonhora uye kusimba.Sezvo iyo yekudziya uye yekutsikirira mudziyo inogona kushanda mumatanho, jekiseni kuumba haingogone kuumba zvikamu zvepurasitiki zvine maumbirwo akaomarara, asi zvakare ine yakakwirira kugadzirwa kwemhando uye yakanaka mhando.Naizvozvo, kuumbwa kwejekiseni kunotora chikamu chikuru mukuumbwa kwezvikamu zvepurasitiki, uye majekiseni molds anodarika hafu yemapurasitiki ekuumba.Majekiseni ejekiseni anonyanya kushandiswa kuumba thermoplastics, uye zvishoma nezvishoma akashandiswa kuumba thermosetting mapurasitiki mumakore achangopfuura.
· Compression mold
Compression mold inonziwo compression mold kana rubber mold.Iyo yekuumba maitiro emhando iyi yekuumbwa inoratidzirwa nekuwedzera epurasitiki mbishi zvinhu zvakananga muakavhurika mold cavity, uyezve kuvhara mold.Mushure mokunge plastiki iri mumamiriro ekunyunguduka pasi pechiito chekupisa uye kudzvinyirira, gomba rinozadzwa nekumwe kumanikidzwa.Panguva ino, iyo molecular chimiro chepurasitiki inosangana nekemikari cross-linking reaction, zvishoma nezvishoma kuoma uye kuumba.Compression molds inonyanya kushandiswa ku thermosetting mapurasitiki, uye zvikamu zvadzo zvepurasitiki zvakaumbwa zvinonyanya kushandiswa kumagetsi switch casings uye zvinodiwa zvezuva nezuva.
Transfer mode
Transfer mold inonziwo jekiseni mold kana extrusion mold.Kuumbwa kwerudzi urwu rwe mold kunoratidzwa nekuwedzera epurasitiki mbishi mukamuri yekudyisa yakapisa, uyezve kushandisa kumanikidza kune epurasitiki zvigadzirwa mukamuri yekudyisa nekoramu yekumanikidza.Plastiki inonyunguduka pasi pekupisa kwakanyanya uye kudzvanywa kwepamusoro uye inopinda mugomba kuburikidza nekudurura sisitimu yeforoma, uye ipapo Chemical cross-linking reaction inoitika uye zvishoma nezvishoma inoomesa uye mafomu.Iyo yekufambisa yekuumba maitiro inonyanya kushandiswa kune thermosetting mapurasitiki, ayo anogona kugadzira zvikamu zvepurasitiki zvine maumbirwo akaomarara.
·Extrusion kufa
The extrusion die inonziwo extrusion head.Iyi mold inogona kuramba ichibudisa mapurasitiki ane akafanana-sectional shape, akadai semapaipi epurasitiki, tsvimbo, mapepa, nezvimwewo. Iyo yekupisa uye inodzvinyirira mudziyo we extruder yakafanana neyemushini wejekiseni.Plastiki iri munzvimbo yakanyungudutswa inopfuura nemumusoro wemuchina kuti igadzire zvikamu zvepurasitiki zvinoramba zvichiumbwa, uye kugona kwekugadzira kwakanyanya kukwirira.
·Pamusoro pemhando dzezviumbwa zvepurasitiki zvakanyorwa pamusoro, kune zvakare mavacuum anoumba mold, akatsikirirwa mweya mold, blow mold mold, uye pasi-inopupa epurasitiki mold.
