It was a good day for England's boxers with five men guaranteeing themselves a medal by reaching the semi-finals. Welterweight Neil Perkins beat Northern Ireland's Thomas Hamill, whose flyweight team-mate Ryan Lindberg lost to England's Don Broadhurst.
Stephen Smith, James DeGale and Frankie Gavin also went through along with Wales' Darren Edwards.
But Scots Kris Carslaw and Craig McEwan, Northern Ireland's Eamonn O'Kane and Wales' Matthew Edmonds lost.
England team captain Perkins looked in solid shape as he saw off Hamill 39-19 and said he was looking for further improvement.
 | This means the world to me, it's my Olympics and I'm going home with a medal |
Perkins said: "You still have not seen the best of me in this tournament and by the time the final comes I will be at my best. I will not be happy until I have got the gold."
Broadhurst picked off Northern Ireland's gutsy Ryan Lindberg 36-27, Smith retired Indian Dwiaker Prasad in round three and Degale proved too classy for Kenyan Daniel Shisia in a 23-11 verdict.
Gavin set up a semi-final clash against Australian Leonardo Zappavigna with a highly impressive third round stoppage of Nigerian Rasheed Lawal.
Wales featherweight Edwards guaranteed himself a medal with a comprehensive 36-14 win over Malaysia's Eddey Kalai.
"This means the world to me, it's my Olympics and I'm going home with a medal," said the Port Talbot man.
Bantamweight Matthew Edmonds was disappointed with his 21-8 loss against Louis Julie of Mauritius "I just don't know what to say, I'm gutted," he said. "I just couldn't get to him."
Scot Kris Carslaw was stopped in round two by impressive Indian Vijender.
Northern Irish middleweight O'Kane lost 28-19 to Samoan Warren Fuavailili and will now hang up his gloves.
"Whenever I threw punches I was catching him but the judges weren't pressing the buttons," said O'Kane.
"I am normally a good sportsman and I did my best but I thought I scored at least five more points in that last round.
"He wasn't throwing anything but what are you supposed to do.
"I have trained twice a day every day for this event, but the judges didn't recognise the punches I threw.
"I always planned to retire after these Games," said the 24-year-old.
