20.500.12556/RUL-130015 Primerjava klasičnega in konformnega hlajenja orodja za brizganje termoplastov Comparison of classical and conformal cooling of molding tool for thermoplasts V magistrskem delu je predstavljeno hlajenje orodja za injekcijsko brizganje izdelka iz polifenilen sulfida. Primerjali smo preprosto izvedbo hlajenja obravnavanega predela gravure z ravnimi izvrtinami na neenakomerni razdalji od gravure ter konformno izvedbo hlajenja, kjer hladilni kanali sledijo obliki gravure na enakomerni razdalji. Učinkovitost obeh metod smo primerjali z merjenjem temperature orodja po koncu brizga. Hlajenje orodja smo obravnavali tudi s teoretičnega vidika s preračunom toplotne bilance orodja ter simulacijo hlajenja prereza stene izdelka pri različnih temperaturah orodja. Z metodo diferenčne dinamične kalorimetrije, smo na podlagi entalpij taljenja kristalne strukture določili stopnje kristalizacije vzorcev, izdelanih pri različnih pogojih hlajenja. In the following master's thesis, we discussed cooling of the mould for injection molding of a part made from polyphenylene sulfide. We compared simple cooling channels design with straight drilled holes at an uneven distance from the mould core and conformal cooling design, where the cooling channels follow the shape of the mould core at the almost uniform distance. The effectiveness of both cooling methods was compared by measuring the core temperature at the end of injection cycle. Mould cooling was also considered from a theoretical point of view by calculating the heat balance of the mould and simulating the cooling of the cross section of molded part's wall at the different mould temperatures. Using differential dynamic calorimetry, we determined the degree of crystallization of samples produced under different cooling conditions based on the melting enthalpies of the crystal structures. injekcijsko brizganje hlajenje orodja konformni hladilni kanali polifenilen sulfid diferenčna dinamična kalorimetrija injection moulding mould cooling conformal cooling polyphenylene sulfide differential dynamic calorimetry true false false [U.
