20.500.12556/RUL-140065 Razvoj modularnega orodja za brizganje plastičnih okvirjev različnih dimenzij Development of modular tool for pressure injection moulding of plastic frames of different dimensions Zaključna naloga obravnava sistematičen razvoj modularnega orodja za brizganje družine izdelkov. Modularno orodje z izmenljivimi oblikovnimi vložki omogoča brizganje več vrst podobnih izdelkov z hitro menjavo med verzijami. Prav tako kot pri modeliranju ene družine izdelkov se modularno orodje modelira istočasno oz. s pogledom na vse vrste izdelkov v družini. Cilj naloge je zmanjšanje stroškov za novo orodju in izdelava orodja s hitro menjavo med tremi verzijami izdelkov. Pregledali in analizirali smo zahteve naročnika in naredili koncept z najnižjimi stroški in najboljšo rešitvijo postavitve oblikovnih vložkov. Med razvojem orodja se je zaradi spremembe zahtev kupca večkrat spremenil koncept postavitve oblikovnih vložkov, kar je podaljšalo razvoj konstrukcije in dodatno upočasnilo menjavo med verzijami. Pri izvajanju procesa razvoja modularnega orodja smo se poslužili med drugim viharjenju idej, skiciranju, CAD modeliranju in izdelavo ustreznih analitičnih in numeričnih preračunov. Izbrati smo morali tudi najboljši sistem dolivanja za vse vrste izdelkov brizganih na orodju pri čemur nam je pomagala moldflow simulacija. The final thesis deals with the systematic development of a modular injection molding tool for a product family. A modular tool with interchangeable inserts enables the injection of several types of similar products with a quick change between versions. Just like when modeling one product family, the modular tool is modeled at the same time or with a view of all types of products in the family. The aim of the task is to reduce the costs for the new tool and to create a tool with a quick change between three product versions. We reviewed and analyzed the client's requirements and made a concept with the lowest costs and the best solution for the placement of inserts. During mould developtment, due to changes in the customer's requirements, the concept of placing elements changed several times, which prolonged the development of the tool and additionally slowed down the change between versions. During the development process of the modular tool, we used, among other things, brainstorming, sketching, CAD modeling, and making appropriate analytical and numerical calculations. We also had to choose the best filling system for all types of products injected on the tool, which was helped by moldflow simulation Modularno orodje brizganje CAD modeliranje Moldflow Modular tool Pressure injection CAD modeling Moldflow true false false [D.
