Paddy Barnes, Michael Conlan and Tommy McCarthy all failed to secure medals after quarter-final defeats.
Barnes lost to Jasurbek Latipov, while Conlan went down to Vladimir Nikitin on all three scorecards and heavyweight McCarthy was beaten by Argentina's Yamil Peralta.
Conlan, who moved up to bantamweight from flyweight for the tournament, vowed to bounce back.
"It wasn't a great performance but it was my first step up into the weight against probably the strongest boxer in the weight so I'm happy enough," he said.
"In a year's time I'll probably be a different man. I was hurting him with shots, I just didn't get the result.
Barnes tweeted: "That's it all over! Was out on my feet in the first round and didn't recover, blurred vision for three rounds with head clashes."
He added: "Fighting with no headgear is good, but to fight six times in ten days without it is impossible."
Jason Quigley of Donegal won his bout though to secure at least a bronze medal.
