description The utility model discloses a dry type transformer coil casting mold, which comprises a mold body in which an annular casting chamber is arranged. A flexible gasket and a clamping piece are sequentially arranged at one end of the mold body at least. Supporting rings are also arranged and can block and cover openings arranged at the two ends of the casting chamber of the mold body from the bottom of the flexible gasket when in working. The ring surface of the supporting ring facing toward the internal side is a smooth plane. Since the supporting ring structure is adopted at the two ends of the dry type transformer coil casting mold and one ring surface of the supporting ring is the smooth surface, resin in contact with the smooth plane is flat and is free of concaves, and the de-molded coil only requires small grinding to the burrs and edges and can be input into the assembly process. Thereby, the cutting process of the end part is saved and the production efficiency is improved.
