Yog hais tias koj twb hnov cushion teeb meem nyob rau hauv koj txhaj txheej txheem, Koj paub tus qhia tej yam tshwm sim: tsis ua hauj lwm, tsis txaus siab, inconsistent txhaj tshuaj loj — tag nrho cov nqi ntau npaum li cas ntawm cwjpwm yuav tsi tau, pov tseg. Cushion yog ib lub tswvyim tseem ceeb heev thiab xyaum hauv txhaj tshuaj molding, Thaum nws muab ib tug tsim nyog "buffer" los xyuas kom meej tias rov qab siab los ntawm qhov txhaj tshuaj tuas thiab packs cov khoom nyob rau hauv cov txhaj tshuaj cavity li xav tau.

cushion yuav tsis yooj yim paub, thiab feem ntau yuav siv sij hawm haus taus. Hauv zaj no peb yuav kawm txog qhov no, Peb lub hom phiaj yog obfold: Pab raws li ib tug nco ntsoov xav cushion raws li qhov uas txhaj tshuaj molding tej teeb meem uas koj yuav muaj tej yam; thiab muab ib co tshuaj uas yooj yim los soj ntsuam thiab enact.

Ua ntej peb tsiv mus nyob rau cov ntsiab lus, Wb tham txog lub ntsiab txhais ntawm "cushion." Ua li cas? Vim hais tias nws yuav txawv ntawm lub tshuab tshuab thiab kav khw. Yuav kom ntse siv cov ntaub ntawv nyob rau hauv daim no, Nws tseem ceeb heev uas yuav tau nkag siab li cas koj lub tshuab yog defining cushion. yeej tseem zoo, muaj ob lub ntsiab txhais:

• Screw qhov chaw kawg ntawm tus tuav theem
• Tus neeg thoob tsib to nrog rau pem hauv ntej yuav pom tseeb tias tus screw mus txog txhua kis thoob plaws hauv txoj kev txhaj tshuaj ua ntej los yog ob theem

Qee zaus, Ob tug zauv no tej zaum yuav yog tib yam. Tsis tau muaj lwm zaus— piv txwv li, Yog hais tias muaj screw bounceback (uas tej zaum yuav tsum tau thiab txais ntaub ntawv rau cov ntaub ntawv los yog qhov chaw uas hu rau tuav pressures) — cov zauv sib txawv. Ntsuam xyuas koj cov machinery cov ntaub ntawv los xyuas kom meej tias koj nyob nraum "hais lus tib yam" thaum nyeem qhov no thiab lwm yam ntaub ntawv hais txog cushion teeb meem.

Tam sim no tias peb muaj ib baseline rau defining cushion, Wb saib tej teeb meem uas txhaj tshuaj molded qhov chaw uas ib inconsistent cushion (los yog tsis cushion) ua tau kom muaj peev xwm ua tau:

Feem ntau ua rau Inconsistent Cushion los yog tsis cushion

Incomplete/unformed qhov chaw: Qhov no yog ib qhov teeb meem heev uas yuav tshwm sim yog ib cushion tsis tam sim no, los sis tsis tam sim no nyob rau hauv tus nqi zoo. Raws li teev saum toj no, Lub hom phiaj ntawm cushion yog guarantee tias siab los ntawm qhov txhaj tshuaj mas hloov mus rau cov khoom nyob rau hauv lub cavity kom zoo packing thiab tuav siab.

Siab yuav tsum ua tib zoo xam rau ib feem tsim thiab machinery, thiab yog reliant raws li txoj kev ua hauj lwm raws li nws yuav tsum tau. Tsis cushion, Ntau variability yog nkag tau rau hauv lub siab equation, ua yuam kev.

Nco ntsoov tias yuav luag tag nrho puab tsaig Muaj ib tug "kev ruaj ntseg buffer" ua li ntawd txawm tias thaum lub screw xoom tawm, Nws tsis tau hu kawg ntawm lub barrel (uas yuav ua rau nws kim heev rau machinery, thiab yog ib yam txaus ntshai). Yog hais tias lub cushion tsis tam sim no, Muaj zoo tas qhov chaw ntawm cov screw thiab cov sprue. Nws tseem tsuas zajlus tias packing/tuav siab yuav ua deb heev nyob rau hauv no scenario.

Inconsistent txhaj tshuaj loj: Yog hais tias koj lub tshuab tsis tuav ib cushion zoo ib yam li cushion, Qhov tshuaj tiv thaiv kab mob npaws yeej txhaj koob tshuaj tivthaiv no rau txhua qhov yuav inconsistent, Ntau dua los yog tsawg dua cov khoom yuav raug txhaj rau hauv lub cavity rau txhua txhaj koob tshuaj tivthaiv. Txawm tias tej zaum tseem yuav acceptably ua, inconsistent txhaj tshuaj loj yuav snowball rau hauv teeb meem loj nrog tshuab setup. Qhov no kuj yuav ua rau inefficiencies nyob rau hauv cov khoom siv.

Yog koj xav tias tej zaum koj yuav muaj teeb meem nrog cushion vim cov tsos mob saum toj no (los yog lwm tus), saib rau hauv cov tshuaj nram qab no:

Saib koj lub cushion teev: Nws yog ib tug nqi txaus siab hloov rov qab siab los ntawm lub tsev txhaj tshuaj rau lub pwm? Nco ntsoov tias thaum txhaj koob tshuaj tivthaiv loj thiab ntau lwm yam kev ntsuas molding ntsuas yog ua los ntawm ntim, cushion yuav tsum tau gauged nyob deb li cas. Ntim yuav muaj ntau variable thaum loj los yog me screw diameters yog nkag tau. Muaj ib tug loj screw diameter, Yuav los ntim ib leeg yuav uas ua rau yuav luag tsis cushion hlo. Ib txoj cai zoo ntawm thumb rau cushion nyob deb li cas yog 6 millimeters.

Saib xyuas koj lub siab: Tshawb kom paub tseeb tias koj muaj txaus cushion ua ntej zaug rau kauj ruam no. Ces, Kos: Yog muaj txaus rov qab siab los ntawm lub tshuab txhaj tshuaj kom txaus pob khoom rau hauv lub cavity, thiab tuav siab los ntawm cov tuav theem? Yog hais tias ib feem ntawm ib txoj tsim los yog ib tug loj tshaj koj feem ntau manufacture, tej zaum yuav tau kho kom zoo dua qub.

Txaus cushion thiab txaus siab teev yog txoj kev ceev tshaj los daws cov teeb meem no. Yog, txawm li ntawd los, Qhov teeb meem no tseem tsis remedied, Sim cov kev kuaj yooj yim los txiav txim seb machinery tej teeb meem tej zaum yuav kiam:

• Siv ib tug "dummy" slug insert rau hauv lub txhaj tshuaj nozzle tswv yim los thaiv cov khoom uas muaj cov khoom siv (kev kuaj ntawd).
• Nqa cov nozzle mus cuag tus sprue.
• Charge thiab hluav taws txhaj tshuaj ntawm resin (cushion).
• Gauge qhov twg tus screw terminates. Yog koj raug kev nyuaj siab ntxhov siab, koj yuav tsum ua tib zoo xav txog tej uas koj nyeem hauv phau Vajlugkub.. Ntsuam xyuas cov barrel, ntxaij; thiab ntiv nplhaib los yog puas tsuaj.
