The invention discloses a handle forming mechanism and belongs to the technical field of metal wire bending and forming machinery. The handle forming mechanism comprises a base, a mold head seat, an action vat, a pair of wire laying devices and an upper mold frame. A stand column set is fixed at one side of the base. A lower mold frame is fixed on the top of the stand column set, and an allowance cavity is arranged in the middle of the lower mold frame. The mold head seat is fixed with one side of the lower mold frame, a handle foot forming groove is arranged in the upper surface of the mold head seat, and a mold handle matching cavity is arranged in the middle of the mold head seat. A mold head is composed of a semi-cylinder body and a mold handle, handle foot forming molds are respectively arranged at two sides of the semi-cylinder, and the mold handle is arranged at one side of the semi-cylinder body. The action vat is fixed on the base. The pair of wire laying devices is arranged at two sides facing upwards of the lower mold frame. A holding arm frame is fixed on the upper mold frame, a first holding arm is connected at one other end of the holding arm frame, and one side of the first holding arm is provided with a first holding arm arc cavity. A second holding arm is connected at the other end of the holding arm frame, and one side of the second holding arm is provided with a second holding arm arc cavity. Operation intensity is relieved, efficiency is improved, handle quality is ensured, and operation and maintenance are convenient.
