Chinhu chikuru chekugadzira kugadzira ndeye hydraulic press.Basa remushini we hydraulic press muchina wekutsikirira ndere kuisa kumanikidza kupurasitiki kuburikidza ne mold, kuvhura mold uye bvisa chigadzirwa.

Kudzvinyirira kuumbwa kunonyanya kushandiswa kuumbwa kwemapurasitiki ematombo.Kune iyo thermoplastics, nekuda kwekuda kugadzirira isina chinhu pamberi, inoda kupiswa uye kutonhora neimwe nzira, saka kugona kwekugadzira kwakaderera, uye kushandiswa kwesimba kwakakura.Uyezve, zvigadzirwa zvine mwero akaomarara uye saizi chaiyo haigone kumanikidzwa.Nokudaro maitiro mazhinji akananga kune zvimwe zvehupfumi jekiseni kuumbwa.

Thecompression molding muchina(press for short) inoshandiswa kuumba is hydraulic press.Kutsikirira kwayo kunoratidzwa mune zita rematani, kazhinji, kune 40t ﹑ 630t ﹑ 100t ﹑ 160t ﹑ 200t ﹑ 250t ﹑ 400t ﹑ 500t mutsara wemichina.Iko kune anopfuura matani anopfuura chiuru emitambo yakawanda.Izvo zvikuru zviri mukati mezvinyorwa zvepepanhau zvinosanganisira kushanda tonnage, ejection tonnage, platen size yekugadzirisa kufa, uye sitiroko yepiston inoshandiswa uye ejection piston, nezvimwewo. Kazhinji, matemplate epamusoro uye ezasi ekudhinda ane zvigadzirwa zvekupisa uye kutonhora. .Zvikamu zvidiki zvinogona kushandisa chando chichitonhora (hapana kupisa, chete inotonhorera mvura) yekuumba uye inotonhorera.Shandisa iyo yekupisa yekupisa chete yekupisa yepurasitiki, iyo inogona kuchengetedza simba.

Zvinoenderana nechiyero che otomatiki, michina yekutsikirira inogona kukamurwa kuita mitsipa yemaoko, semi-otomatiki mashini, uye zvizere otomatiki.Zvinoenderana nehuwandu hwezvikamu dzepasina gwenzi, inogona kukamurwa kuita kaviri-layer uye akawanda-layer-layer.

A hydraulic press muchina wekumanikidza unofambiswa ne hydraulic transmission.Kana uchidzvanya, plastiki inotanga kuwedzerwa kune yakashama mold.Zvadaro fudza mafuta ekumanikidza kune silinda inoshanda.Kutungamirwa nekoramu, piston uye danda rinotakurika zvinofamba zvichidzika (kana kumusoro) kuvhara mold.Pakupedzisira, simba rinogadzirwa ne hydraulic press rinoendeswa kune mold uye rinoshanda papurasitiki.

Ipurasitiki mukati me mold inonyunguduka uye inonyorovesa pasi pechiito chekupisa.Iyo mold inozadzwa nekumanikidzwa kubva kune hydraulic press uye kemikari inoitika.Kuti ubvise hunyoro uye humwe hunyoro hunogadzirwa panguva yekugadziriswa kwemapurasitiki uye kuve nechokwadi chemhando yechigadzirwa, zvinodikanwa kuita kudzoreredza uye kupera simba.Kurumidza kuwedzera uye chengetedza.Panguva ino, resin mupurasitiki inoenderera mberi nekuita kemikari.Mushure meimwe nguva yenguva, insoluble uye infusible yakaoma yakasimba nyika inoumbwa, uye kuumbwa kwekusimbisa kunopedzwa.Iyo mold inozarurwa pakarepo, uye chigadzirwa chinotorwa kunze kwekuumbwa.Mushure mekunge mold yacheneswa, denderedzwa rinotevera rekugadzira rinogona kuenderera.

Zvinogona kuonekwa kubva pane zviri pamusoro apa kuti tembiricha, kudzvanywa, uye nguva zvinhu zvakakosha zvekumanikidza kuumbwa.Kuti uvandudze kugadzirwa kwemuchina uye kuchengetedzwa uye kuvimbika kwekushanda, kumhanya kwekushanda kwemuchina zvakare chinhu chakakosha chisingagoni kuregererwa.Naizvozvo, iyo yepurasitiki hydraulic press inoshandiswa kudzvanya inofanirwa kukwanisa kuzadzisa zvinotevera zvakakosha zvinodiwa:

① Kudzvanya kunofanirwa kuve kwakakwana uye kuchinjika, uye kunodiwawo kusvika nekuchengetedza iyo yakafanotemerwa kudzvanywa mukati meimwe nguva yenguva.

② Iyo inofambiswa danda re hydraulic press inogona kumira uye kudzoka chero nguva mukurova.Izvi zvinonyanya kukosha kana uchiisa molds, pre-pressing, batch kuchaja, kana kutadza.

③ Iyo inofambiswa danda re hydraulic press rinogona kudzora kumhanya uye kushandisa kushanda nesimba chero nguva mukurohwa.Kusangana nezvinodiwa zvezviumbwa zvehurefu hwakasiyana.

Dhepamiro inoshamisa yeHydraulic Press inofanirwa kunge iine kukurumidza kumhanya mune isina chinhu kusati kwatanga kuumbwa, kuti udzikise kugadzirwa kwemuchina uye kudzivisa kuderedzwa kana kuomesa kwepurasitiki kuyerera.Kana murume wechirume achibata purasitiki, iyo yekuvhara yekuvhara inofanirwa kuderedzwa.Zvikasadaro, iyo mold kana kuisa inogona kukuvadzwa kana hupfu hunogona kugezwa kubva kumukadzi wemukadzi.Panguva imwecheteyo, kudzikisira kumhanya kunogona zvakare kubvisa zvizere mweya muumbi.
