Optimizacija hlajenja orodja za brizganje plastike
diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje Strojništvo
Abstract
V diplomskem delu je predstavljeno konstruiranje štirignezdnega orodja za brizganje polipropilenskih pokrovov s ciljem optimizirati hlajenje in posledično skrajšati cikel brizganja. Izvedena je bila analiza možnih konstrukcijskih rešitev, predhodnega dvognezdnega orodja in brizganega materiala. Opravili smo preračune, rezultate le-teh smo nato uporabili za določitev uporabljenega brizgalnega stroja glede na njegovo zapiralno silo. Ob upoštevanju ugotovitev in zahtev smo skonstruirali posamezne komponente in jih sestavili v celoto. Izdelali smo tudi vso potrebno tehnično dokumentacijo za izdelavo orodja. Rezultat je delujoče orodje, ki ima najmanj 5 sekund krajši čas cikla brizganja in 150 % večjo produktivnost v primerjavi s predhodnim orodjem.

| Secondary title: | Optimisation of a plastic injection-moulding tool |
| Secondary abstract: | The thesis presents the construction of a four cavity tool for injection molding of polypropylene lids, for which the target was to optimize cooling and consequently shorten the molding cycle time. We analyzed the possible construction solutions, the previously used two-cavity tool and the molding material. We made calculations on which of the results would then be used to determine the molding machine to use, based on the clamping force of the machine. Taking into account the findings and requirements, we constructed every individual component of the mold and assembled them. Furthermore, we also prepared all the necessary technical documentation for the manufacturer of the mold. The final result is a working mold that has a shorter injection cycle time of at least 5 seconds and 150% higher productivity compared to the previous mold. |
