The invention provides a core head forming method of manual core making. The core head forming method of manual core making comprises the following steps: firstly, a core head forming metal rod is placed in a core box core head hole, one end surface of the core head forming metal rod is parallel and level to the bottom end surface of the core box core head hole, the other end of the core head forming metal rod enters a cavity of a core box, and then the core box is filled with core sands to make a core; and after the core is made, the core sands with the core head forming metal rod are baked, and the core head forming metal rod is cured in the core sands, wherein during pouring, the core head forming metal rod has the action of positioning and supporting the core sands. The core head forming method of manual core making is suitable for manual core making; when a core head is too small and long without liability in forming, the problem that the core head is not liable to form as being too small (with the diameter smaller than 10mm) and having the length-diameter ratio being larger than 5 during manual core making is solved; and according to the core head forming method, the core is convenient to make, the core sands can be positioned and supported, and the production efficiency is improved.
