Process for the manufacture of rigid molds for the molding of molten metals, characterized in that one or several models are disposed on a plate or disc of a secondary material, such as plaster, wood or other, which has receiving cavities of half of each model, this secondary piece being housed in a suitable chassis and having on it a thin separating sheet before dressing the hardenable synthetic resin that will cover the models and will extend above the secondary piece acquiring in its hardening the bas-reliefs according to the upper half free of the models, and once obtained this first mold already rigid is placed in the base of the chassis with the models above and covered with a separating sheet repeats the operation of pouring synthetic resin in the molten state, which in its later hardened will be the other complementary mold for the obtaining of the models, having foreseen cores or cores suitable they leave in the molds holes and channels suitable for the subsequent entrance and distribution of the melted metal in the facing bas-reliefs that present the respective faces of these.
