Abstract

Diplomsko delo prikazuje snovanje prototipnega orodja za brizganje plastike na nekonvencionalen način. Postopek snovanja je prilagojen tehnologiji izdelave s selektivnim laserskim sintranjem iz alumida. Obravnavan je izdelek iz realnega industrijskega okolja. Izvedene simulacije brizganja prikazujejo deformiranje izhodiščnega modela. Na podlagi teh je zastavljena rešitev, ki obsega spremembo geometrije izdelka in izvedbo orodja s konformnimi hladilnimi kanali. Simulacija brizganja v takšno orodje prikaže zadovoljiv rezultat. Orodje je izvedeno v obliki normalne dvoploščne konstrukcije z izmenljivimi vložki, sintranimi iz alumida. Prikazan je postopek računalniškega konstruiranja orodja v programskem okolju Solidworks in priprava vložkov na izdelavo s selektivnim laserskim sintranjem. Geometrija orodnih vložkov s konformno oblikovanim hladilnim sistemom je z uporabo konvencionalnh postopkov in materialov neizvedljiva, kar upravičuje uporabo alternativnih materialov v povezavi z dodajalnimi tehnologijami. Kot prednost uporabe dodajalnih tehnologij se izkaže tudi sama enostavnost postopka izdelave, saj je s časovnega in stroškovnega vidika hitrejši in ugodnejši od konvencionalnega.

Secondary title:	Use of alternative materials for injection molding prototyping tools
Secondary abstract:	Thesis shows the design of a prototype tool for injection molding in an unconventional way. The process of design is adapted to the manufacturing technology by selective laser sintering of alumide. A product from the real industrial environment is selected.With injection molding simulations, the deformation of the base model is shown. On the basis of these the solution, that involves changes in the product geometry and tool design with conformal cooling channels, is based. Simulation of injection molding in such a tool displays a satisfactory result. The tool is implemented in the form of normal two plate design with interchangeable inserts, sintered from alumide. The process of tool design, is shown in computer aided design environment Solidworks and preparation of inputs to production by selective laser sintering. The geometry of the tool inserts with conformably shaped cooling system is unproducible with conventional manufacturing processes, thus justifying the use of alternative materials in conjunction with the additive technologies. As an advantage of using additive fabrication proves herself simplicity of the manufacturing process, since the time and cost perspective quicker and more comfortable than conventional.
