Narrative:

We were given a climb to 14;000 feet after level off at 6;000 feet where we were in constant light/moderate turbulence. Controller asked us to expedite climb to 14;000 for traffic. I open climb that gave thrust climb/open climb in the FMA. When aircraft had approximately 1;000 FPM climb; I put thrust levers in flx/mct (maximum continuous thrust) to give the aircraft more thrust to expedite. The aircraft with the autopilot on lagged in pitching up to the flight director and airspeed jumped from 250 to 270. I opted for selected speed and put 230 knots to initiate a faster climb rate. Speed was exceeded for approximately 30 seconds.
