Description

Technical Field

[0001] The invention belongs to the technical field of aluminum casting machines, and in particular relates to a spraying mechanism of a centrifugal aluminum casting machine. Background Art

[0002] During the centrifugal aluminum casting process, a spraying mechanism is required in the cavity preparation stage. The specific spraying steps are as follows:

[0003] ‌Cavity preparation‌: Prepare a suitable cavity and preheat it; then, you need to apply paint or spray a release agent, and a spraying mechanism will be used at this time to facilitate demolding of the casting;

[0004] Pouring and other steps: After spraying is completed, pouring, cooling and solidification, demoulding and post-processing steps are carried out to finally complete the centrifugal aluminum casting process.

[0005] The traditional centrifugal aluminum casting machine's spraying mechanism has a single function and a fixed spraying range. It cannot be flexibly adjusted according to the actual size of the pipe mold, which leads to material waste. In addition, the traditional spraying mechanism can only be used for spraying on either the vertical or horizontal centrifugal aluminum casting machine. When a factory processing castings needs to spray both the vertical and horizontal centrifugal aluminum casting machines, it is generally necessary to prepare matching spraying mechanisms for different centrifugal aluminum casting machines. This not only increases costs, but also takes up factory space.

[0006] In order to solve the above problems, a centrifugal aluminum casting machine spraying mechanism is proposed. Summary of the invention

After the spraying is completed, the hydraulic telescopic rod 202 is retracted to separate the atomizing nozzle 437 from the pipe mold, and then it is moved to the next pipe mold by the moving device 1 to repeat the above operation to spray it.

[0069] See also Fig. 9 and Fig.11As shown, when it is necessary to spray the surface of the casting, first adjust the spray device 4 to a point where the middle space is larger than the size of the casting by the above method, then press the limit clamp 420 to rotate the arc plate 423, and rotate it 180° so that the atomizing nozzle 437 in the middle of the arc plate 423 is aligned with the center position, then close the atomizing nozzles 437 on both sides, and then put the arc plate 423 on the outside of the casting, and then spray the outer surface of the casting; at the same time, pressing the limit clamp 420 can also remove the arc plate 423, so that when the parts of the arc plate 423 are damaged, it is easy to disassemble and repair them.

[0070] It should be further explained that when the present invention is in use, the circumference of the atomizing nozzle 437 is concentric with the tube mold, ensuring that during spraying, the distance between each atomizing nozzle 437 and the inner wall of the tube mold is the same, so that the sprayed release agent is more uniform.

[0071] Positioning of the spraying device 4: A laser pen can be set at the center position of one end face of the driving shaft 406, and a cross bar can be movably set at the inlet of the tube mold for auxiliary positioning. There is a center point on the surface of the cross bar, and this center point is the center of the tube mold. When the laser line is perpendicular to the center point, the positioning is completed. After the positioning is completed, the cross bar can be removed for the next spraying work. Embodiment 3

[0074] See also Figure 9-11As shown, when it is necessary to spray the release agent on pipe molds of different lengths, first rotate the threaded column 438 in sequence from the direction close to the drive shaft 406 according to the actual usage, so that it drives the spherical plug 408 to move toward the direction of the atomizing nozzle 437 to block the movable hole 434, thereby closing the pipeline of the atomizing nozzle 437. At the same time, the synchronous arc plate 439 cooperates with the spherical nut 440, thereby driving the auxiliary screw 409 to close the pipelines of the atomizing nozzles 437 on both sides through the spherical plug 408, until the spraying range of the atomizing nozzle 437 is adjusted to a suitable length, thereby meeting the use of pipe molds of different lengths.
