magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo
Abstract
V magistrskem delu je predstavljen razvoj hladilnega sistema orodja za injekcijsko brizganje plastike. V teoretičnem delu naloge je opravljen celovit pregled obstoječih konvencionalnih in konformnih konstrukcijskih rešitev ter ključnih analitičnih modelov, na osnovi katerih smo zasnovali štiri različice temperirnih sistemov oblikovnih orodnih plošč. Posamezne rešitve se med seboj razlikujejo v dolžini hladilne poti, preseku kanalov in njihovi poziciji glede na delovno površino. Zasnovane koncepte smo analizirali po metodi končnih elementov, kjer smo preverjali termično učinkovitost odvajanja toplote iz orodne votline, vpliv termo-mehanskih obremenitev in hidravlične izgube skozi temperirni sistem. V drugem delu magistrske naloge je predstavljeno eksperimentalno vrednotenje posameznih rešitev, s katerimi smo validirali zasnovane numerične modele in predlagali smernice za oblikovanje temperirnega sistema. Ugotovili smo, da pravilno zasnovan konformni hladilni sistem omogoča bolj učinkovito odvajanje toplote iz orodja, doseganje krajših ciklov brizganja in zagotavlja enakomerno temperaturo po površini gravurnega vložka.

Secondary title: |
Development of a conformal cooling system for injection molding tool used for polymers |
Secondary abstract: |
The master's thesis presents the development of the cooling system of the plastic injection molding tool. A comprehensive review of existing conventional and conformal design solutions and key analytical models was performed in the theoretical part of the thesis. We designed four different cooling systems. The individual solutions differ in the length of the cooling channels, the cross-section of the channels, and their position in relation to the working surface. We have performed numerical analyses for the designed solutions, where we have checked the cooling efficiency, the influence of thermo-mechanical loads, and hydraulic losses through the tempering system. In the second part of the master's thesis, the experimental evaluation of the individual solutions is presented, which we used to validate the numerical model. We found that a properly designed conformal cooling system allows for more efficient heat dissipation from the tool and ensures a uniform temperature across the surface of the tool insert. |
