1: Vim li cas cov khoom txhaj tshuaj molding thiaj li muaj qhov nqes hav demoulding?
Feem ntau, cov khoom txhaj tshuaj pwm raug ua los ntawm cov pwm sib xws. Tom qab cov khoom txhaj tshuaj pwm raug pwm thiab kho, nws raug coj tawm ntawm qhov pwm qhov lossis lub hauv paus, feem ntau hu ua demolding. Vim yog qhov molding shrinkage thiab lwm yam laj thawj, cov khoom yas feem ntau raug qhwv nruj rau ntawm lub hauv paus lossis raug kaw hauv qhov pwm qhov, thiab lwm yam. Tom qab pwm qhib, pwm tsis tuaj yeem tso tawm tau, uas yooj yim rau cov khoom txhaj tshuaj pwm kom raug tso tawm ntawm pwm thiab tiv thaiv qhov chaw ntawm cov khoom txhaj tshuaj pwm kom tsis txhob khawb thaum demolding. Thaum tsim cov pwm txhaj tshuaj, sab hauv thiab sab nraud ntawm cov khoom txhaj tshuaj pwm yuav tsum muaj lub kaum sab xis demoulding tsim nyog raws li qhov kev taw qhia demoulding.
2: Cov yam cuam tshuam rau qhov nqes hav demolding ntawm cov khoom txhaj tshuaj molding
1) Qhov loj ntawm lub kaum sab xis demolding nyob ntawm qhov ua tau zoo ntawm cov khoom txhaj tshuaj pwm, cov duab ntawm cov khoom, piv txwv li, qhov siab lossis qhov tob ntawm cov khoom, phab ntsa tuab thiab qhov xwm txheej ntawm qhov chaw, xws li qhov roughness ntawm qhov chaw, cov kab ua tiav, thiab lwm yam.
2) Lub kaum sab xis ntawm cov yas tawv yog loj dua li ntawm cov yas mos;
3) Cov duab ntawm cov khoom uas yuav tsum tau txhaj tshuaj pwm yog qhov nyuaj dua, lossis cov khoom yas nrog ntau qhov molding xav tau qhov nqes hav demoulding loj dua;
4) Yog tias qhov siab ntawm cov khoom txhaj tshuaj molding loj dua thiab qhov tob dua, qhov demolding slope me dua raug saws;
5) Lub phab ntsa tuab ntawm cov khoom txhaj tshuaj molding nce ntxiv, lub zog ntawm lub qhov sab hauv los qhwv lub hauv paus loj dua, thiab lub kaum sab xis ntawm daim ntawv yuav tsum loj dua.
