[0020] When in use, the gantry 1 of the device is installed across the mold cart conveying rail. After the finished guardrail is taken out, the mold cart conveying rail continues to convey the mold cart 8 forward to the cleaning station, and then the lifting drive assembly is actuated, and the lifting frame 2 is driven down under the action of the linear guide mechanism, thereby driving the wind knife 7 to descend to the specified position, and then the high-pressure hot air is turned on. As the guardrail mold cart moves forward, the wind knife 7 uses high-pressure hot air to clean the inner surface of the guardrail mold cart. In addition, a dust collector can be set next to the cleaning station to suck the floating dust generated during cleaning into the dust collector. After cleaning, the lifting drive assembly reverses to lift the wind knife 7, and the mold cart 8 can be conveyed forward normally.
