Abstract
U ovom radu opisana je tehnologija tlačnog lijeva. Opisane su izvedbe strojeva za tlačni lijev, materijali koji se primjenjuju te parametri kojima se utječe na tijek procesa i svojstva odljevka. Nadalje su opisani najčešći tipovi grešaka kod tlačnog lijeva. U eksperimentalnom dijelu rada za zadani odljevak konstruirane su dvije izvedbe uljevnog sustava za tlačni lijev: izvedba uljevnog sustava sa jednim ušćem te izvedba uljevnog sustava sa dva ušća. Za svaku izvedbu uljevnog sustava izrađene su dvije varijante sa različitim položajima preljeva te su provedene simulacije u programskom paketu QuikCAST 2014. Za obje izvedbe uljevnog sustava provedena je optimizacija gibanja tlačnog klipa kako bi se postigao željeni oblik vala i izbjeglo zarobljavanje zraka. Na posljetku je istražen utjecaj temperature predgrijavanja kokile na tijek punjenja i skrućivanje odljevka.
Abstract (english)
The subject of this thesis is high pressure die casting process. Types of machines used, the alloys used and parameters which affect the course of the process and quality of the casting are described. Furthermore, most common defects in high pressure die casting process are described. In the experimental part of the thesis, two versions of gating system are designed for a given casting: version with one gate and version with two gates. For each version two additional variations of gating system are designed, each with a different overflow placement, and simulation of the process carried out using the QuikCAST 2014 software. For both gating system versions, optimization of plunger movement during a slow shot is carried out in order to achieve the desired wave shape and avoid air entrainment. Lastly, an effect of die temperature on the filling of the die cavity and solidification of the casting is investigated.
