Tuag casting yog cov txheej txheem rau loj-tsim hlau cov khoom thiab cov khoom. Pwm tsim yog ib qho ntawm cov kauj ruam tseem ceeb tshaj plaws hauv cov txheej txheem vim tias cov duab thiab cov yam ntxwv ntawm cov pwm yuav cuam tshuam ncaj qha rau cov khoom kawg. Cov txheej txheem tuag casting yuam molten hlau rau hauv pwm siv lub siab thiab nws yuav tsum muaj pwm nrog cov lus qhia meej kom ua tiav txoj haujlwm.
Qhov tseem ceeb ntawm Mould Design
Pwm tsim cuam tshuam rau cov duab, configuration, zoo, thiab uniformity ntawm cov khoom tsim los ntawm cov txheej txheem tuag casting. Cov khoom siv tsis raug tuaj yeem ua rau cov cuab yeej lossis cov khoom siv corrosion, nrog rau cov khoom lag luam tsis zoo, thaum tsim qauv zoo tuaj yeem txhim kho kev ua haujlwm thiab sijhawm ntau lawm.
Yam Tseem Ceeb Ua rau Kev Tsim Pwm Zoo Muaj ntau ntau yam pwm tsim los xav txog thaum txiav txim siab txog qhov tsim nyog rau ib qhov project. Qee qhov xwm txheej no suav nrog:
• Tuag daim duab
• Nqaij qaib
• Sib faib kab
• Thawj Tswj Hwm
• Ribs
• Qhov thiab qhov rais
• Cov cim
• Phab ntsa thickness
Daim ntawv
Draft yog qhov degree uas cov tub ntxhais pwm tuaj yeem tapered. Yuav tsum muaj cov txheej txheem meej meej kom ua tau zoo eject lub casting los ntawm qhov tuag, tab sis vim cov cua ntsawj ntshab tsis tas li thiab nws txawv raws li lub kaum sab xis ntawm phab ntsa, nta xws li hom molten alloy siv, cov duab ntawm phab ntsa, thiab qhov tob ntawm cov pwm. tuaj yeem cuam tshuam cov txheej txheem. Pwm geometry tuaj yeem cuam tshuam cov qauv. Feem ntau, untapped qhov yuav tsum tau tapering, vim muaj kev pheej hmoo ntawm shrinkage. Ib yam li ntawd, cov phab ntsa sab hauv kuj tuaj yeem txo qis, thiab yog li yuav tsum tau tsim ntau dua li cov phab ntsa sab nrauv.
Nqaij qaib
Lub fillet yog ib qho kev sib txuas ntawm concave siv los ua kom lub kaum sab xis. Lub kaum ntse ntse tuaj yeem cuam tshuam cov txheej txheem casting, yog li ntau cov pwm muaj cov fillets los tsim cov npoo sib npaug thiab txo qhov kev pheej hmoo ntawm kev ua yuam kev. Nrog rau kev zam ntawm txoj kab sib cais, fillets tuaj yeem ntxiv ze li ntawm txhua qhov chaw ntawm pwm.
Kev faib kab
Lub parting kab, los yog parting nto, txuas txawv seem ntawm pwm ua ke. Yog hais tias txoj kab sib faib tsis raug qhov chaw los yog ua rau deformed los ntawm kev ua haujlwm, cov khoom yuav nkag mus rau hauv qhov sib txawv ntawm cov pwm, ua rau cov pwm tsis sib xws thiab ntau dhau seaming.
Cov thawj coj
Bosses yog tuag cam khwb cia uas ua hauj lwm raws li mounting cov ntsiab lus los yog stand-offs nyob rau hauv pwm tsim. Cov neeg tsim khoom feem ntau ntxiv ib lub qhov rau cov qauv sab hauv ntawm tus thawj coj los xyuas kom meej cov phab ntsa tuab hauv cov khoom molded. Cov hlau nyhav muaj qhov nyuaj ua rau cov thawj coj sib sib zog nqus, yog li kev sau thiab ribbing tej zaum yuav tsim nyog los daws qhov teeb meem no.
Ribs
Tuag cam khwb cia ribs tuaj yeem siv los txhim kho cov khoom siv zog hauv cov khoom uas tsis muaj phab ntsa thickness xav tau rau qee yam kev siv. Kev xaiv tav tav tuaj yeem txo txoj hauv kev ntawm kev ntxhov siab tawg thiab tsis sib xws. Nws kuj tseem muaj txiaj ntsig zoo rau kev txo cov khoom hnyav thiab txhim kho cov peev txheej sau.
Qhov thiab Windows
Xws li qhov los yog qhov rais nyob rau hauv ib tug tuag cam khwb cia pwm ncaj qha cuam tshuam qhov yooj yim ntawm ejecting ib tug tiav molding thiab enables cov creation ntawm ntau yam ntaub ntawv. Ntxiv nta, xws li overflows, flashovers, thiab cross feeders tej zaum yuav tsim nyog los tiv thaiv pliaj casting nyob rau hauv lub qhov los yog cov khoom tsis zoo ntws nyob ib ncig ntawm lub qhov.
Cov cim
Cov neeg tsim khoom feem ntau suav nrog cov npe lag luam lossis cov khoom lag luam logo hauv pwm tsim cov khoom lag luam tuag. Thaum cov cim tsis feem ntau cuam tshuam cov txheej txheem tuag casting, lawv siv tuaj yeem cuam tshuam cov nqi tsim khoom. Tshwj xeeb, ib lub logo lossis lub cim yuav tsum tau ntxiv cov hlau ntim rau txhua qhov chaw tsim khoom. Conversely, ib tug recessed cim yuav tsum tau tsawg raw khoom thiab yuav txo tau cov nuj nqis.
