Aluminium Low Pressure Tuag Casting

Khoom Paub meej

Aluminium casting pwm rau qhov tsis tshua muaj siab aluminium casting feem ntau yog muab tso rau saum lub qhov cub kaw lossis tuav lub qhov cub. Compressed cua nkag mus rau hauv lub crucible los yog tuav lub cub tawg, uas ua rau tsis tshua muaj siab (0.06 ~ 0.15MPa) nyob rau saum npoo ntawm cov hlau molten, ua rau cov kua txhuas los ntawm lub standpipe thiab puv nws. Yog ib txoj kev pwm thiab casting siv los tswj solidification.

Low-pressure cam khwb cia aluminium

Tsawg-siab aluminium casting yog ib txoj kev casting uas tso cai rau cov kua aluminium alloy ua kom tiav cov txheej txheem ntawm cov pwm pwm kab noj hniav hauv qab qis, yog li tau txais cov khoom zoo. Vim yog qhov tsis tshua muaj siab (0.06 ~ 0.15MPa), nws yog hu ua low pressure cast aluminium.

Cov txheej txheem ntawm lub tshuab tsis tshua muaj siab aluminium casting yog: nyob rau hauv lub kaw crucible lossis tuav lub qhov cub, los ntawm cov cua qhuav compressed, cov kua txhuas txhuas yuav nkag mus rau hauv cov yeeb nkab pub raws li riser nyob rau hauv qhov kev txiav txim ntawm huab cua siab thiab nce, thiab smoothly nkag mus rau hauv pwm los ntawm lub puab ntws channel kab noj hniav zoo, thiab tswj cov huab cua siab nyob rau saum npoo ntawm cov kua nyob rau hauv lub crucible los yog tuav lub cub tawg kom txog rau thaum lub txhuas casting yog kiag li solidified thiab tsim. Tom qab ntawd cov huab cua nyob rau saum npoo ntawm cov kua txhuas yog tso tawm, lub unsolidified aluminium alloy kua nyob rau hauv lub standpipe ntws rov qab mus rau lub crucible los yog tuav lub cub tawg, lub pwm qhib thiab lub casting yog muab tshem tawm. Cov yam ntxwv tseem ceeb ntawm cov txheej txheem qis-siab aluminium casting txheej txheem yog tias cov filling ceev thiab siab tuaj yeem hloov kho kom haum.

Muaj ob hom kev txhaj tshuaj molding rau qis-siab aluminium casting: metallic thiab non-metallic. Hlau pwm feem ntau yog siv rau loj-scale thiab batch zus tau tej cov txhuas castings, thaum uas tsis yog-hlau pwm yog tsuas yog siv rau ib-thooj, me-batch ntau lawm. Piv txwv li, cov xuab zeb pwm, graphite pwm, ceramic pwm thiab fused pwm plhaub tuaj yeem siv rau kev siv qis qis aluminium casting, thiab feem ntau siv hauv kev tsim khoom. Txawm li cas los xij, huab cua permeability thiab lub zog ntawm cov xuab zeb pwm cov khoom siv rau cov khoom siv hluav taws xob qis qis yuav tsum siab dua qhov kev nqus casting. Cov pa roj hauv cov kab noj hniav yog siv los ntawm cov pa tso pa tawm thiab cov xuab zeb qhov.

Txhawm rau kom tau txais txiaj ntsig zoo ntawm qhov tsis tshua muaj siab cam khwb cia aluminium, aluminium alloy pub lub casting los ntawm hauv qab mus rau sab saum toj nyob rau hauv siab. Thaum tsim cov txheej txheem, kev txiav txim siab yuav tsum tau muab rau kev ua kom cov khoom kom deb ntawm lub rooj vag ua ntej thiab tom qab ntawd cia lub rooj vag khov kho kom cov casting solidifies. Thaum lub sij hawm tus txheej txheem no, lub rooj vag yuav tsum tau noj kom ua tiav sequential solidification.

Lub hauv paus ntsiab lus ntawm cov txheej txheem qis qis rau aluminium alloy tuag castings:

Aluminium alloys tau siv dav hauv kev tsim khoom lag luam vim lawv muaj zog castability thiab durability. Aluminium alloy low-pressure casting feem ntau yog hais txog qhov qis qis hauv qab txhaj tshuaj ntawm aluminium alloy tov nyob rau hauv qis-siab siab tej yam kev mob, tso cai rau cov txhuas alloy tov kom nce siab nyob rau hauv tag nrho ceev raws li riser yeeb nkab mus rau lub pouring point. lub qhov ncauj, thiab tom qab ntawd sau cov pwm tsis tu ncua ntawm qhov ceev tsis tu ncua. Tom qab cov pwm puv lawm, lub siab tuav txheej txheem yog nqa tawm los tswj lub shrinkage kab noj hniav, thiab ces nws yog txias thiab solidified, thiab lub siab yog relieved eject lub aluminium alloy tuag-casting ib feem. Tsawg-pressure casting tshuab yog qhov tsim nyog rau kev tsim cov khoom siv nrog cov duab nyuaj thiab cov phab ntsa nyias. Low-pressure casting muaj cov yam ntxwv ntawm cov khoom siv zoo heev, ruaj khov molding, tsim nyog siv hlau, thiab kev lag luam.

Low-pressure casting tso cai rau cov kua hlau ua rau cov pwm kab noj hniav nyob rau hauv siab los tsim ib tug casting. Vim tias lub siab siv tsawg, nws yog hu ua low-pressure casting. Cov txheej txheem yooj yim yog tias cov cua compressed nkag mus rau hauv lub sealing depletion chamber ua rau cov kua hlau nce mus tas li ntawm cov yeeb nkab ua kua hauv qab qhov kev txiav txim ntawm cov roj siab thiab ntws mus rau pwm kab noj hniav los ntawm lub rooj vag. Nyob rau tib lub sijhawm, lub siab nyob rau hauv cov kua theem yog nce mus txog rau thaum lub aluminium alloy yog tom qab tuag-casting solidifies, cov roj siab nyob rau hauv cov kua theem tso tawm, tso cai rau cov unsolidified molten hlau nyob rau hauv cov kua yeeb nkab yuav ntws mus rau lub insulator, thiab cov casting raug thawb tawm ntawm lub tog raj kheej.

Txoj kev loj hlob ntawm txhuas tuag-casting pwm:

Aluminium tuag-casting cov ntaub ntawv muaj qhov pom tseeb zoo dua cov khoom siv hlau tsoos. Lawv cov qauv thiab corrosion kuj yog qhov zoo, tshwj xeeb tshaj yog cov alloy yog sib zog dua li cov khoom siv hlau. Nrog rau txoj kev loj hlob ntawm lub tsheb kev lag luam thiab invention ntawm lub txias chamber tuag-casting tshuab, tuag-casting Nrog rau txoj kev loj hlob ntawm cov hom ntawm txhuas cov ntaub ntawv, nws muaj peev xwm kwv yees hais tias cov txheej txheem alloy tuag-casting yuav maj mam hloov steel castings raws li lub kev taw qhia tseem ceeb ntawm kev txhim kho yav tom ntej.

Muaj ntau yam uas cuam tshuam rau qhov zoo ntawm aluminium die-casting. Ib qho ntawm feem ntau yog cov tuag-casting pwm tsim. Txij li thaum tuag-casting qhov chaw yog tsim nyob rau hauv pwm, ib zaug muaj teeb meem nrog cov pwm zoo, nws yuav cuam tshuam rau qhov tuag-casting qhov chaw. Piv txwv li, yog tias cov pwm tuag-casting tsis muaj zog txaus, nws yuav ua rau deformation thaum lub sij hawm tuag-casting, uas ua rau muaj qhov sib txawv loj ntawm qhov tiav thiab cov qauv tsim, los yog tej zaum yuav muaj ntau qhov pores thiab tawg ntawm sab hauv ntawm qhov chaw. pwm thiab cov khoom siv tsis zoo, ua rau cov txhuas cuam tshuam thaum tuag-casting. Qhov saum npoo ntawm qhov chaw yog qhov tsis sib xws thiab nyuaj kom tau raws li qhov xav tau tiag tiag. Yog li, tam sim no txoj hauv kev tseem ceeb los txhim kho qhov zoo ntawm aluminium alloy tuag-casting qhov chaw yog los txhim kho qhov zoo ntawm cov pwm. Txawm li cas los xij, tseem muaj qee qhov tsis txaus ntawm kev siv cov khoom siv raw rau cov pwm tuag-casting hauv kuv lub teb chaws, thiab kev tsim tshuab ntawm cov pwm tuag casting tseem muaj qhov tsis zoo piv nrog cov teb chaws tsim. Nyob rau tib lub sijhawm, Cov txheej txheem txhawb nqa thiab cov chaw muaj feem cuam tshuam nrog kuv lub teb chaws txoj kev lag luam pwm tuag kuj tsis zoo tag nrho. Cov laj thawj no tau cuam tshuam txoj kev loj hlob ntawm kuv lub teb chaws cov pwm tuag-casting.

Qhov zoo ntawm aluminium alloy tsis tshua muaj siab casting
