The utility model relates to a manufacture mold for a high-voltage prefabricated direct-current cable accessory, which is provided with a first mold group, a second mold group, a third mold group, a fourth mold group and a fifth mold group, wherein the first mold group forms a terminal stress cone in the direct-current cable terminal manufacture process, the second mold group forms an insulation body with a plurality of umbrella skirts, the third mold group forms a high-voltage shielding layer in the middle joint manufacture process, the fourth mold group forms a reinforced insulation layer, and the fifth mold group forms an outer semi-conductive shielding layer with joint stress cones at both ends. The shapes of middle joints and terminals can be controlled according to the optimum design requirement, and the problem of the adverse influence of space charge accumulation caused by the traditional manual winding is solved through integral injection molding and one-step forming, and the problems of long heating curing time after winding and forming and process errors of material heat expansion and cold contraction in a molding process are solved. Therefore, the production efficiency is effectively improved, the terminals and the middle joints are formed by prefabricated elements in factories and can carry out electric tests, and the reliability of the product quality is ensured.
