On Sunday, the 36-year-old Serb broke to open the contest and was never threatened as Gojo managed only a single break chance in the entire match.
Next up for Djokovic is top-ranked American and ninth seed Taylor Fritz, who advanced with a tidy 7-6(2) 6-4 6-4 win over Swiss qualifier Dominic Stricker.
Fritz will head into the showdown as the only player yet to drop a set but still stinging from the 6-0 6-4 beating Djokovic laid on him in the quarter-finals of the Cincinnati Open.
"Obviously Taylor has been now an established top-10 player for the last couple of years," said Djokovic, who has won all seven career meetings with Fritz.
