[0028] Through the implementation of the above technical solution, when the casting mold surface spraying device is used to spray the mold, the mold to be sprayed is first placed under the slide rail 13, and then the liquid is supplied to the spraying unit through the liquid supply unit, and the spraying unit is able to reciprocate and spray above the mold in coordination with the extension and contraction of the hydraulic cylinder 3; in addition, the sliding contact between the roller 7 and the slide rail 13 makes the spraying unit move more smoothly in the horizontal direction, and the action of the drag chain 12 enables the hose 10 to move with the drag chain 12, so that the hose 10 will not be excessively deformed, thereby extending the service life of the hose 10.

[0029] In this embodiment, in order to further provide a liquid supply unit, the liquid supply unit includes a liquid storage barrel 17, and a liquid outlet is provided at the lower end of the liquid storage barrel 17; the hose 10 is connected to the liquid outlet, and a stop valve 19 is installed at the liquid outlet, and a booster pump 18 is installed at the end of the hose 10 near the stop valve 19. Because the paint has a certain viscosity and relatively poor fluidity, the device is provided with an agitator 16 and a booster pump 18. The agitator 16 is continuously operated during the spraying process, and the booster pump 18 can meet the continuous flow of paint from the paint nozzle 9.

[0030] In this embodiment, the liquid storage barrel 17 is equipped with an agitator 16 and a liquid level probe 15, the agitator rod of the agitator 16 extends into the liquid storage barrel 17, and the inner end of the agitator rod is equipped with a stirring blade. Before spraying, the liquid in the liquid storage barrel 17 can be stirred by the agitator 16, and the stirring blade installed can make the stirring more sufficient, thereby obtaining a spray liquid with a better mixing effect.

[0031] In this embodiment, the spraying unit includes a spraying component and a conical cover 11 arranged at the bottom of the spraying component; a compressed air pipe 5 is inserted into the spraying component, and a compressed air nozzle 8 for vertically spraying compressed air downward is installed at the inner end of the compressed air pipe 5; the end of the hose 10 extending into the spraying component is connected to a laterally extending paint nozzle 9, and the outlet of the paint nozzle 9 is arranged below the compressed air nozzle 8.

When the mist paint enters the conical cover 11, it will diffuse to the mold surface. The conical cover 11 will also reduce the waste caused by the mist paint dispersing in the air to a certain extent.

[0036] In this embodiment, a PLC controller 20 electrically connected to the liquid supply unit, the spray unit and the electric control end of the hydraulic cylinder 3 is also included.

[0037] In the utility model: the base 1 is used to support and fix all mechanisms; the support frame 2 includes at least two columns and a crossbeam connecting the columns, and the columns are fixed on both sides of the ingot casting machine respectively; the hydraulic cylinder 3 controls the spraying part to move forward and backward by telescoping the hydraulic rod; the mold is a mold 4 to be sprayed, which is fixed in the ingot casting machine and operates with the operation of the ingot casting machine; the compressed air pipe 5 is a hose 10, which is connected to an external compressor to provide compressed air; the air pressure regulating valve 6 is used to adjust the appropriate air flow; the roller 7 facilitates the movement of the spraying part; the compressed air nozzle 8 is conical in shape and made of glass; the paint nozzle 9 is made of L-shaped glass, connected to one end of the hose 10, and located directly below the compressed air nozzle 8; the hose 10 conveys paint, one end of which is connected to the paint nozzle 9, and the other end is connected to the booster pump 18; the conical cover 11 is connected to the spray The bottom of the coating component; the drag chain 12 is for the convenience of fixing the hose 10, and each section of the drag chain 12 is connected by a bolt 26; the slide rail 13 provides a travel track for the spraying component; the electromagnetic induction switch 14 is used to limit the moving position of the spraying component; the liquid level probe 15 is convenient for real-time monitoring of the remaining paint in the liquid storage barrel 17; the agitator 16 is used to stir the paint; the liquid storage barrel 17 stores the paint; the booster pump 18 increases the paint pressure in the liquid storage barrel 17 to facilitate normal outflow, one end is connected to the liquid storage barrel 17, and the other end is connected to the hose 10; the stop valve 19 controls the paint flow; the PLC controller 20 controls and adjusts the gas pressure, the stroke of the hydraulic cylinder 3, the agitator 16 and the booster pump 18; the fastener 21 is used to fix the position of the compressed air nozzle 8 and the paint nozzle 9, so as to better form a mist after the paint is sprayed out.

[0038] Before spraying, add the paint into the liquid storage barrel 17, and turn on the agitator 16 to stir it to make it uniform, operate the PLC controller 20 to set parameters such as air pressure and hydraulic cylinder 3 stroke; when spraying, turn on the booster pump 18, the paint flows into the paint nozzle 9 through the hose 10, and the compressed air is transmitted to the compressed air nozzle 8 through the compressed air pipe 5, which will generate a negative pressure environment above the paint nozzle 9. The paint will also flow from the hose 10 to the nozzle position and shoot towards the cone cover 11 under the negative pressure environment, forming a mist. When the mist paint enters the cone cover 1111, it will accumulate and spread evenly. The liquid is dispersed to the surface of the mold; the hydraulic cylinder 3 pushes the spraying component to move along the slide rail 13 according to the stroke set by the PLC controller 20. At this time, the drag chain 12 moves synchronously to the right until the spraying component senses the electromagnetic induction switch 14 on the right and stops, and quickly retreats to the electromagnetic induction switch 14 on the left. This process will re-spray the surface of the mold 4 to be sprayed, completing a spraying process; during spraying, when the amount of paint in the liquid storage barrel 17 is lower than the liquid level probe 15, the PLC controller 20 will issue an alarm to remind the operator to add material in time; as the ingot casting machine runs, all mold surfaces are sprayed with the release agent to complete the operation.
