Ashrafi defeated Australia’s Aiden Stilley to take the first gold of the evening in the men’s +78kg weight division.
He used his height and leg length to maximum effect in both rounds, winning the first 11-2 and the second by technical superiority as his 15-point lead gave him for a richly deserved triumph.
Italy’s Matteo De Angelis and Spain’s Iván Lysenko Serrano earned the bronze medals.
Iranian girls Parnian Noori and Aynaz Nasiri had won two gold medals on the first day.
