Izdelava orodja za brizganje plastike

Dolinar, Blaž (author), Mole, Nikolaj (mentor), Pušavec, Franci (comentor)

V diplomskem delu smo predstavili tehnologije za izdelavo orodja za brizganje plastike iz orodnih jekel. Kjer smo glede na zahteve določili optimalno tehnologijo obdelave posameznega segmenta orodja, obdelovalna orodja ter njihove obdelovalne parametre. Za izdelavo obdelovalnih programov smo uporabili različne strategije vrtanja, frezanja ter obdelave z žično erozijo v programskem okolju BobCAD-CAM. Orodje smo izdelali z uporabo CNC frezalnega stroja ter stroja za žično erozijo. Med samo obdelavo smo preverjali dimenzijske točnosti obdelave ter obrabo orodij, kjer pa nismo zaznali večjih odstopanj. Glede na uspešno delovanje orodja smo ugotovili, da so uporabljene tehnologije zadostovale za kvalitetno izdelavo sestavnih delov orodja.

Abstract

In Diploma thesis we presented the technologies for manufacturing plastic injection molding tool from tool steels. Based on the requirements, we determined the optimal processing technology for each tool segment, the machining tools, their processing parameters. For NC programming we used different drilling, milling and wire strategies in the BobCAD-CAM software environment, where we created the machining programs. The tool was manufactured using a CNC milling machine and electric discharge machine. During the processing, we checked the dimensional accuracy of the machining and the wear of the tools, where we did not detect any significant deviations. Given the successful operation of the tool, we concluded that the technologies used were sufficient for the quality manufacturing of the tool components.
