Quomodo facit? iniectio fingens machina cochlea insolitum sonum lapsus facere
Si cochlea incipit labi per tempus praefigurans, axialis cochleae motus sistit ut pressione pergit gyrari. Solet cochleae lapsus deducet ad degradationem materiae ante iniectionem mold. sed etiam brevem iactum, extensum processus exolvuntur et alia uber qualitas problems.
Potentia processus parametri
Humilis temperatus in dorso dolii plerumque causa principalis infusionis cochleae slippage plasticae. Dolium iniectio machinae coronae in tres partes divisa est. A tergo pascendi sectionem, gracilis polymerus fusilis formatur in calefactione et compressione materiae. Liquefacta cinematographica dolio coniuncta est. Sine hoc tenue, haud facile moveat globulos deinceps. Materia in sectione feedo calefieri debet ad punctum criticum ad movendum cinematographicum criticum producendum. tamen, saepe materia in dolio retentionis tempus est nimis breve ut polymerus hanc temperiem attingat. Haec res fortasse ob apparatum angustum est, debitae figurae minoris dolii et stupra fecit.
Brevior commorationis temporis potest facere polymer liquefaciunt vel insufficiens mixtura, quae ad stupra lapsus vel tincidunt. Duae hic viae simplices ad tractandum cum hoc problemate sunt. Additur parva materiae copia ex fine dolii ad purgandum et ad temperatura liquanda retunditur. Si commorationis est brevis, temperatura liquatio infra valorem dolii siccus erit. Secunda methodus est intueri operis operis et si marmorari inventum est, nigro-maculatus vel levis alba, indicat materiam in dolio non bene mixtam.
Impulsum armorum
Si causa cochleae slippage causatur processus armorum quam processus parametri, tunc vestis stupra et dolii verisimile est esse problema key. Ut cum esu sectioni, Cum resina liquescit in sectione compressionem cochlea, adhaeret muro cylindrici. Cum cochlea revolvatur, materia e muro cylindrico avulsa et deinceps deportata. Si quae sunt in pressione et dolio zonae gerunt, tunc cochleae non valent deinceps traditio materiae. Si lapsum suspectum, cochleae et dolium cohiberi et alvi aptum inter utrumque cohiberi. Si cochleae et doliolum alvi cum plus quam valoris vexillum, initium pro reparandis operibus. Defectus reprehendo anulum (reprehendo valvae) Potest etiam facere cochlea ad lapsus. Cum cochlea revolvatur et plasticized, e contrario anulus in fronte (aperta) situ et in contactu cum taxatione anuli sedem. Si Nolite Annuli in retrorsum (clausa) status, seu inter deinceps et retro statum, polymer fusilis resistet transire per intervallum inter anulum Sistere et sedem anuli.
Si dubium est de Stop Ring, repone statim. Resina cibarium Hopperum etiam causa esse potest elabi in variis cochleis infusione fingendi. Recta Hopper consilio clavis est ut firmum materiae traditio, sed hoc saepe neglectum est. In genere, nova globulos tam uniformis magnitudinis opus in platea Hopper cum subito compressionem zona (subito angusti fundo) . tamen, hoc casu non est quando materiae REDIVIVUS adduntur. Figura et magnitudo globulorum longe alia sunt post rursus contusa, quae in uniformitate feed. Inconvenienter pastio significat cochlea non posse conservare pressionem uniformem in Liquefacto, inde in skidding. Ad solvendam hanc quaestionem et differentiam quantitatis inter materiam REDIVIVUS et novam materiam solvendam, experiri possumus uti per Hopper quod est pressio plana zona (cum torto CLIVUS in fundo) .
1.Area formse anulus hydrau apertus angustus est
Forma foramen vis oleum pressura foramen = forma foramen oleum pressura area
Si vis crescere forma foramen vis cum maxima pressura determinatur, vos can tantum foramen oleum pressura anulus area auget forms, et forma foramen oleum pressionis anulum area augere potes augendo diametrum cylindrici vel diam anconem minuendo.
Causae et countermeasures Glue lacus in iniectio fingens machinae productionem
Per productionem machinae iniectio, ea quae gignuntur sub situ gluten stillante ob aliquas causas, calefactio anulus involvitur ab Glue, sicut productio tempus protrahitur, calefactio anulus corrumpitur, occultatum periculum mali qualitas producta, etc. , gravi lacus glutinis totum dolium involvit, quod consequitur plurimum sumptus et perditio temporis sustentationem
In productione, in COLLUM (et vocavit COLLUM caput) concentricis sit portae sleeve formse, et duae sphaerae arcte cooperentur, aliter gluten effluo. In genere, semidiameter duarum sphaerarum sit idem, sed apertura sphaerica collium paulo minus est 0.5 ~ 1mm portae manica, coaxiality tolerantia minor vel aequalis 0.25 ~ 0.3. The following is an analysis of the causes of leakage of Glue
1.The mould has no locating ring or the locating ring does not match the forming machine. When the mould is installed, the mould inlet hole and the gun barrel nozzle are not on the coaxality, and the position has a little deviation. Every time the mould is produced, a little bit of glue leaks out, there is no obvious change, but with the increase of production time, leakage will be more and more tired, the last leakage will slowly wrap around the heating ring;
2.The fixing screw of the nozzle turret is loose, so that the barrel nozzle and the Mould Gate are not at the same concentricity. When the nozzle is pressed against the mould gate, there is a little deviation in the position. When the mould is produced, parum gluten effluat, eisdem partibus producto, there is no obvious change, sed cum longiore tempore productio, leakage will be more and more tired, the last leakage will slowly wrap around the heating ring;
3, formam portae sleeve habet fracturam situ, CERVIX productio iniectio et forma manica porta non potest arctissima inter se cohaerere, omni tempore iniectio gluten, parum liquefactum erit glutinum e fomace extra, sicut productio tempus longum, lacus gluten magis ac magis defessus erit, postremo lacus in calefactio anulum tardius involvit;
4, COLLUM os habet fractio- nem situ, COLLUM productio et operimentum portae formae non potest esse artissima, toties iniectio glutinum, parum liquefactum erit glutinum e fomace extra, sicut productio tempus augetur, lacus gluten erit magis defessus, postremo lacus in calefactio anulum tardius involvit;
5.Angulus formae R operculum portae et COLLUM iniectio non aequat, there will be a gap between the injection nozzle and the mold gate cover when the production is close, every time the injection glue, there will be a little melt out of the mold, sicut productio tempus augetur, leakage of rubber will be more and more tired in view of the above situation,
there are the following countermeasures:
1, it is recommended that the mold is equipped with positioning ring, although no positioning ring will save its cost, but no positioning ring, not only has the potential to produce leakage of rubber, when changing the mould, the time of changing the mould will be lengthened, the cost of the heating ring will be saved if the heating ring is damaged by one time leakage of the glue, hand gun barrel shooting table forward, touch the mold, feel the nozzle and mold gate sleeve is in the same concentricity, also can use thin paper pad in mold glue mouth, the nozzle touch mold, and then exit, see whether the paper hole and the nozzle hole consistency;
2. Check the cause of loosening and fastening of the tightening screws of the Turret; the corresponding confirmation method: Before production, hold the turret shooting table by hand, when touching the mould, whether the handle shooting nozzle and the mould gate sleeve are on the same concentricity, also can use thin paper pad in the mold glue mouth, shoot the mouth after touching the mold, and then exit, see whether the paper hole and shoot mouth hole consistency;
3.Temporary solution due to mold gate cover and nozzle damage: use soft metal such as copper pad on the mold gate cover, nozzle forward contact with the copper plate top tight, back, after the nozzle hole in the nozzle position, permanent Countermeasures: The Corresponding Gate Sleeve or nozzle is re-polished, so that the R angle of both the gate sleeve and the nozzle on the Turret are in smooth contact with the production;
4.Glue leakage caused by mismatch of R angle of gate sleeve or nozzle, replace Gate Sleeve or Nozzle to keep the R angle of gate sleeve and nozzle consistent;
Hoc tempore, the causes and improvement methods of glue leakage in injection molding production mainly have the above several kinds, there is no good method of automatic detection of glue leakage in the production process, and the management can only increase the time period to inspect if there is glue leakage, cum continua progressio iniectio technology, ut developed in futurum ut statim deprehendere lacus armorum, ut productio INJECTIONE CUMATIOR INTELLIGENTI!
