The inner walls of the four U-shaped frames are respectively fixedly connected to the front sides of the two first closing plates and the two second closing plates. One sides of the plurality of clamping blocks are respectively fixedly connected to the two sides of the two exhaust boxes and the two liquid discharge boxes. Slots adapted to the clamping blocks are formed on the four U-shaped frames. The plurality of clamping blocks respectively fit with the plurality of slots. One sides of the plurality of first plates and the plurality of second plates are respectively fixedly connected to the two sides of the two exhaust boxes and the two liquid discharge boxes. The bottom parts of the plurality of lifting blocks are respectively fixedly connected to the top ends of the plurality of clamping columns. Slide holes are formed on the first plates, the second plates, the U-shaped frames and the clamping blocks. The bottom ends of the plurality of clamping columns respectively penetrate through the plurality of slide holes and extend below the U-shaped frames.

The top parts on both sides of the two first filter meshes are respectively slidably connected to the plurality of first limiting strips. The top parts on both sides of the two second filter meshes are respectively slidably connected to the plurality of second limiting strips.

[0012] In a possible design, first triangular blocks and second triangular blocks for facilitating the cleaning of impurities are respectively fixedly arranged on the inner walls of the bottoms of the two exhaust boxes and the two liquid discharge boxes.

[0013] In a possible design, infusion tubes and gas transmission tubes are respectively fixedly arranged on the front sides of the two first closing plates and the two second closing plates and are in communication with the infusion tubes and the gas transmission tubes.

At the same time, the gas enters the exhaust box through the first pipeline and blows the surface of the mold through the air blowing nozzles to remove impurities or assist in demolding. During the spraying and blowing processes, impurities in the gas and liquid are effectively intercepted by the first filter screen and the second filter screen, ensuring that the sprayed gas and liquid are pure and free of impurities, reducing the blockage of the spray heads and the air blowing nozzles. The filtered impurities are deposited at the bottoms of the exhaust box and the liquid discharge box and are guided by the first triangular block and the second triangular block, facilitating subsequent cleaning and discharge. When it is necessary to clean the inside of the spray box or replace the filter screen, the operator can lift the lifting block upward, so that the clamping column is disengaged from the locked states of the U-shaped frame and the clamping block under the action of the spring, and then place the lifting block on the connecting block to prevent the clamping column from returning to its original position, thereby easily disassembling the first closing plate and the second closing plate. After disassembly, the exhaust box, the liquid discharge box and the filter screen can be thoroughly cleaned to ensure the continuous and efficient operation of the spray box, reduce the occurrence of blocked air holes in the air blowing nozzles and the spray heads. The sealing rings are arranged on the outer sides of the first closing plate and the second closing plate, effectively preventing gas and liquid from leaking during transmission and improving the overall sealing performance. The solenoid valves are installed on the third tube and the fourth tube, and the flow rates of the gas and the liquid are precisely controlled by an external controller to ensure the stability and accuracy of the spraying and blowing processes. The setting of the flange plates facilitates quick connection with external pipelines, improving the flexibility and convenience of the equipment. By ensuring that the sprayed gas and liquid are pure and free of impurities, the spray box provides a more stable and reliable working environment for the die-casting mold, thereby improving the production quality of the product.

[0016] The beneficial effects of the present utility model are as follows:

[0017] In the present utility model, the spray box precisely controls the spraying and blowing processes to ensure timely and effective cooling and cleaning of the die-casting mold, reducing the waiting time during the production process, improving production efficiency, and effectively reducing the blockage of the spray head and blowing nozzle through the disassembly mechanism and filtering mechanism, extending the service life of the equipment, reducing maintenance costs, and making maintenance work such as cleaning and replacing the filter screen simple and fast, reducing the operation difficulty and labor intensity.
