Design of injection molding cooling insert for manufacturing by Selective Laser Melting
Tekeľ, Richard Martin ; Vrána, Radek (referee) ; Koutný, Daniel (advisor)
This bachelor thesis focus on design of a cooling insert so the current mold cycle time will be reduced and it will be possible to manufacture the insert by SLM. Proposed modification includes 1 cooling line with non-circular cross section and disrupt empiric cooling line design recommendations. A research into differences of conventional and additive manufacturing of injection moulding inserts was conducted as well as into theoretical principles needed for a design of cooling lines and preview of similar solutions for the given task. After simulation of current state and obtaining a value of current cycle time, 3 different designs of cooling line were chosen and simulated in order to pick the most suitable one. This cooling design was afterwards modified to get conformal shape and lower distance from critical spot. The last part of thesis interpret the results from simulation of the final cooling line design and estimation of safety against fatigue failure.
