A mold assembly for injection-molding flat-type heat sinks, includes a male mold, a female mold engageable with the male mold, a base mounted on one side of the female mold and having a cavity in communication with the female mold, and a movable block disposed within the female mold and having one side formed with molding structure, whereby a clearance between a flat-type heat sink and the movable block will be eliminated by moving the movable block against the flat-type heat sink.
