Those skilled in the art should know that they will not be elaborated in detail here. The spraying process is an operation step before the die-casting machine molds. The specific working process is that when the release agent is sprayed, the movable mold 1 is first pulled by the driving device 2 and is in a state of being separated from the fixed mold 3, and the two maintain a certain distance, which is equal to the following The rectangular tube body 701 has a length, and a spray pipe 704 is arranged inside the rectangular tube body 701, facing the movable mold 1 and the fixed mold 3 respectively. The nozzle 705 on the spray pipe 704 sprays the surface of the movable mold 1 and the fixed mold 3. When spraying, the rectangular tube body 701 can prevent the atomized release agent from escaping into the workshop. The spraying process is that the pump body 702 extracts the release agent from the external release agent supply equipment, wherein the external release agent supply equipment is not drawn in the figure, and then transports it to the liquid supply pipe 703, and the liquid supply pipe 703 then sprays the release agent from the nozzle 705 on the spray pipe 704 in atomized form to achieve spraying.
