Temperature control device for die casting mold

The utility model relates to a temperature control device for a die casting mold. The temperature control device for the die casting mold comprises the die casting mold, wherein the die casting mold comprises a movable mold body and a fixed mold body, water inlets are formed in one end of the movable mold body and one end of the fixed mold body, water return ports are formed in the other end of the movable mold body and the other end of the fixed mold body, the water return ports are connected with a cooling water tower through a first water pipe, a first temperature sensor and a flow sensor are arranged on the first water pipe, the cooling water tower is communicated with the water inlets through a second water pipe, and a high-pressure delivery water pump, a pressure indicator, a one-way valve, an electromagnetic valve and a second temperature sensor are arranged on the second water pipe. According to the temperature control device for the die casting mold, heat transmitted to the mold by molten metal entering the die casting mold is automatically controlled to be taken away by continuously-circulating cooling water in the mold, the temperature of the mold is lowered and is stabilized within the technical requirement range, and actual production conditions and production requirements in the industry are met.
