magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo
Abstract
V magistrskem delu je predstavljen problem ožiganja injekcijsko brizganih polimernih izdelkov in odzračevanje orodja za injekcijsko brizganje termoplastov. Na začetku smo opisali osnove potrebne za razumevanje injekcijskega brizganja termoplastov, sestavo orodij za brizganje in načine odzračevalnih sistemov orodij. V nadaljevanju smo primerjali orodje s klasičnim odzračevanjem kalupne votline napram orodju s podtlačnim odzračevanjem ob pomoči zunanje vakuumske črpalke. Nato smo primerjali površino izdelkov narejenih z obema metodama, tako, da smo merili hrapavost in geometrijo izdelka. Ugotovili smo, da v primeru vakuumskega odzračevanja zmanjšamo ožiganje površine, s čimer je hrapavost izdelka manjša, izgled površine boljši, hkrati pa s podtlačnim odzračevanjem ne vplivamo na ostale dimenzije izdelka.

Secondary title: |
Analysis of the venting systems of molding tools for processing thermoplastic materials |
Secondary abstract: |
In master's thesis we presented a problem of outgassing of injection molded poylmer parts as well as venting of molds for injection molding. At first, we explaind basic knowledge of injection molding, as well as parts of molding tools and types of venting systems. We compared conventional venting of mold with vacuum assisted mold venting provieded by external vacuum pump. In next step we compared parts surface by measuring roughness and geometry of samples. We found that by vacuum venting, we eliminate outgassing of surface, by which value of roughness is lower and look of measured surface is more desirable. At the same time other dimensions of samples remain unchanged. |
