Die structure with good heat dissipation effect

The invention relates to the technical field of injection molds, and discloses a mold structure with a good heat dissipation effect, the mold structure comprises a lower mold, guide rods are symmetrically fixed on the upper surface of the lower mold, the outer surfaces of the two guide rods are jointly and slidably connected with a lifting frame, a top plate is jointly fixed at the top ends of the two guide rods, and a mold groove is filled with an injection molding material. An electric push rod is controlled to operate to push a lifting frame and an upper mold to descend, the upper mold enters a mold groove to extrude an injection molding material to form the injection molding material, meanwhile, a fan and a liquid pump operate, cooling liquid circularly flows in a cooling channel and a cooling pipe under operation of the liquid pump, the temperature of a model in a lower mold and the mold groove is reduced, and the fan blows airflow to reduce the temperature nearby a structure; and after the electric push
