I-Quick Turn Plastic Injection Molding: The Ultimate Guide Yabaqalayo

Ukubumba ngomjovo weplastiki wuhlelo lokukhiqiza olusebenza ngempumelelo kakhulu oluguqule ukukhiqizwa kwezingxenye zepulasitiki. Kubandakanya ukujova izinto zepulasitiki ezincibilikisiwe zibe isikhunta ukuze udale izimo eziyinkimbinkimbi ngokunemba okuphezulu nokuvumelana. Indlela iyabiza futhi iguquguquka, okwenza kube inketho ekahle yokukhiqiza izingxenye ezinkulu. Kulo mhlahlandlela, sizongena ngokujulile emhlabeni wokubumba umjovo wepulasitiki, sihlanganisa yonke into kusukela emlandweni wayo kanye nezimiso eziyisisekelo kuya ezinhlotsheni ezahlukene zokubumba nemishini esetshenziswa kule nqubo.

Umlando Wokubumba Umjovo Wepulasitiki

Maphakathi nawo-1800, abakhiqizi bakhiqiza amabhola amabhiliyade okuqala e-celluloid, abonisa ukuqala komlando wokubunjwa komjovo wepulasitiki. UJohn Wesley Hyatt waqala ukugunyaza inqubo ngo-1872 futhi wasungula umshini owafaka i-celluloid esikhunjeni. Lo mshini wokuqala wabeka isisekelo senqubo yesimanje yokubumba umjovo wepulasitiki.

Phakathi nekhulu lama-20, ukubumba komjovo wepulasitiki kwakhula kwaduma njengoba abakhiqizi abaningi bebona izinzuzo zako kunezinye izinqubo zokukhiqiza. Ngawo-1950, abakhiqizi bethula umshini wokuqala wokubumba umjovo ozishintshayo, owavula indlela yokukhiqizwa kwezingxenye zepulasitiki ngobuningi. Kusukela lapho, le nqubo iye yavela ngokuthuthuka kwezobuchwepheshe nezinto zokwakha, okuyenza ibe inketho yokwenziwa kwezingxenye zepulasitiki.

Izimiso Eziyisisekelo Zokubumba Umjovo Wepulasitiki

Ukubumba umjovo wePlastiki kuyinqubo eyinkimbinkimbi ebandakanya izingxenye ezimbalwa, okuhlanganisa umshini wokubumba umjovo, izinto zepulasitiki, kanye nesikhunta. Nazi izimiso eziyisisekelo zokubumba umjovo wepulasitiki:

Umshini Wokubumba Umjovo kanye Nezingxenye zawo

Umshini wokubumba umjovo uyinhliziyo yenqubo yokubumba umjovo wepulasitiki, futhi unesibopho sokuncibilikisa impahla yepulasitiki bese uyijova esibunjeni. Idivayisi ihlanganisa izingxenye ezimbalwa, okuhlanganisa i-hopper, isikulufu, umgqomo, neyunithi yomjovo.

I-Plastiki Material kanye nezakhiwo zayo

Izinto zepulasitiki ezisetshenziselwa inqubo yokubumba umjovo kumele zibe nezakhiwo ezithile ezivumela ukuthi zigeleze kalula futhi ziqinise ngokushesha. Lezi zakhiwo zihlanganisa i-viscosity, izinga lokuncibilika kokugeleza, namandla okuqina.

Isikhunta Nokuklanywa Kwaso

Isikhunta siyingxenye ebalulekile yenqubo yokubumba umjovo, futhi ukuklama kwayo kubalulekile ukuze kuzuzwe ukuma okufunayo kanye nekhwalithi yengxenye. Isikhunta siqukethe izingxenye ezimbili, umgodi, kanye nomgogodla, okwenza isimo socezu lokugcina. Isikhunta kufanele sihlanganise umshini wokubumba umjovo kanye nezinto zepulasitiki.

Inqubo yokubumba ngomjovo wePlastiki

The ukufakelwa kwegesi epulasitiki inqubo iqukethe izigaba eziningana: clamping, umjovo, ukupholisa, futhi ejection.

Ukugoqa: Ukuvikela Isikhunta

Isigaba sokuqala senqubo i-clamping, okubandakanya ukuvikela isikhunta endaweni. U-opharetha uxhuma ama-halves amabili esikhunta futhi ajove izinto zepulasitiki esikhunjeni ngeyunithi yomjovo.

Umjovo: Ukuncibilika kanye Nokujova Izinto Zepulasitiki

Isigaba sesibili sihlanganisa ukuncibilika kwempahla yepulasitiki bese uyijova esikhunjeni. Izinto zepulasitiki zichithwa emgqonyeni womshini wokubumba umjovo bese zijova emgodini wesikhunta.

Ukupholisa: Ukuqinisa Ingxenye Yepulasitiki

Isigaba sesithathu sihilela ukupholisa ingxenye yepulasitiki ukuyiqinisa. Isikhunta sipholile ngokusebenzisa amanzi noma amafutha, futhi ingxenye yepulasitiki ivunyelwe ukupholisa futhi iqine ngaphakathi kwesikhunta.

Ukukhipha: Ukukhipha Ingxenye KuMold

Isigaba sokugcina senqubo sihilela ukukhipha ingxenye yepulasitiki esikhunjeni. Esebenzisa izikhonkwane ze-ejector, opharetha uvula isikhunta futhi asuse ucezu emgodini.

Izinhlobo Ezihlukene Zesikhunta Esisetshenziswa Ekubumbeni Umjovo Wepulasitiki

Isikhunta esisetshenziswa ku ukufakelwa kwegesi epulasitiki kubalulekile empumelelweni yenqubo, futhi isikhunta sinquma ukuma kokugcina, ukuthungwa, kanye nekhwalithi yengxenye yepulasitiki. Izinhlobo eziningana zokubumba zisetshenziswa ekubunjweni komjovo wepulasitiki, ngayinye inezinzuzo kanye nokubi.

Isikhunta esinamapuleti amabili

Isikhunta esinamapuleti amabili yisikhunta esilula futhi esisetshenziswa kakhulu ekubumbeni umjovo. Iyunithi yokubopha ibamba ndawonye amapuleti amabili ukwenza isikhunta. Lo musho usuvele usezwini elisebenzayo, usho ngokucacile ukuthi ubani noma yini eyenza. Isikhunta esinamapuleti amabili asibizi futhi silungele ukukhiqizwa kwevolumu ephansi kuya kwephakathi.

Isikhunta esinamapuleti amathathu

Isikhunta esinamapuleti amathathu sifana nesikhunta esinamapuleti amabili kodwa sinepuleti le-stripper eyengeziwe. Umsebenzisi usebenzisa i-stripper plate ukuze akhiphe ingxenye yepulasitiki esikhunjeni, esusa isidingo samaphini ejector. Isikhunta esinamapuleti amathathu sifanelana nokukhiqizwa kwevolumu ephezulu kanye nezicucu ezinamajiyometri ayinkimbinkimbi.

Isikhunta somgijimi esishisayo

Isistimu yokushisa ekubunjweni komgijimi oshisayo igcina impahla yepulasitiki ohlelweni lomgijimi luncibilikile, isusa isidingo sokuthi isikhunta sikhiphe abagijimi ngengxenye. Ukusebenzisa isikhunta sokugijima esishisayo kunciphisa ukumosha kanye nesikhathi somjikelezo futhi kuthuthukisa ingxenye yekhwalithi. Isikhunta se-hot runner sifanelana nokukhiqizwa kwevolumu ephezulu kanye nezici ezinamajiyometri ayinkimbinkimbi.

Isikhunta esigijimayo esibandayo

Isikhunta sokugijima esibandayo yisikhunta sendabuko esisetshenziswa ekubumbeni umjovo. Isistimu yokugijima ekubunjeni ikhipha ingxenye, ikhulise imfucuza kanye nesikhathi somjikelezo. Isikhunta sokugijima esibandayo asibizi futhi silungele ukukhiqizwa kwevolumu ephansi kuya kwephakathi.

Faka isikhunta

Abakhiqizi basebenzisa inqubo yokufaka isikhunta ukubumba izinsimbi zensimbi noma zepulasitiki engxenyeni yepulasitiki. Bafaka into efakwa emgodini wesikhunta bese bejova ipulasitiki nxazonke. Isikhunta sokufaka sifanelana nokukhiqizwa kwevolumu ephansi kuya kwemaphakathi kanye nezithakazelo ngokufaka insimbi noma ipulasitiki.

Izinhlobo Ezihlukene Zemishini Yokubumba Umjovo

Umshini wokubumba umjovo uyinhliziyo yenqubo yokubumba umjovo wepulasitiki. Kunezinhlobo eziningana zemishini yokubumba umjovo, ngayinye inezinzuzo zayo kanye nokubi.
