The invention discloses a sanitary deodorant tee joint die casting mold. The sanitary deodorant tee joint die casting mold comprises a base and a fixed mold plate located at the top of the base. First hydraulic cylinders located at the top of the base are arranged on the two sides of the fixed mold plate, and connecting blocks are connected to piston rods of the first hydraulic cylinders. A movable mold plate located over the fixed mold plate is arranged between the two connecting blocks. The two connecting blocks are fixed to the two sides of the movable mold plate correspondingly. Placing tanks are symmetrically arranged on the adjacent sides of the fixed mold plate and the movable mold plate. An opening of each placing tank is provided with a first fixing column, and the two ends of each first fixing column are fixed to the two side inner walls of the corresponding placing tank correspondingly. The two first fixing columns form a cylindrical structure. Two core plates are slidably installed in each placing tank and located on the two sides of the placing tank correspondingly. According to the sanitary deodorant tee joint die casting mold, the size of a manufactured sanitary deodorant tee joint can be adjusted as needed, and thus the die casting mold is suitable for sanitary deodorant tee joints of various sizes; the structure is simple; using is convenient; and the cost is low.
