20.500.12556/RUL-126928 Načrtovanje in izdelava oblikovne puše za brizganje duroplastičnih izdelkov Design and manufacturing of the tool insert for thermoset injection moulding Po določenem številu izdelanih kosov je potrebno oblikovno pušo v brizgalnem orodju zamenjati. Zato se pojavi potreba po izdelavi nove. Puša se izdeluje na podlagi tehnične dokumentacije, ki je sicer že izdelana, vendar se z dejanskim stanjem ne ujema v popolnosti. Odstopanja se pojavijo zaradi ne dokumentiranih dodelav na oblikovnem delu orodja. Na podlagi meritev in računskega upoštevanja skrčkov smo izdelali novo dokumentacijo. Poleg tega smo prikazali potrebne smernice dimenzioniranja in izdelave oblikovne puše in njene ključne funkcije v orodju. After a certain number of manufactured products, the molding bush in the injection molding tool must be replaced. Therefore, there is a need to make a new one. The bush is manufactured on the basis of tehnical documentation, which has already been made, but does not correspond to the actual situation entirely. Deviations occur due to undocumented refinements on the design part of the tool. Based on the measurments and the calculation of shrinkage, we prepared new documentation. In addition, we presented the necessary guidelines for dimensioning and fabrication of the molding bush and its key functions in the tool. duroplasti brizganje brizgalno orodje skrčki oblikovna puša dimenzioniranje thermosets injection molding injection molding tool shrinkage molding bush dimensioning true false false [G.
