[0024] Embodiment:

[0025] Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a coating spraying device inside a mold, including

[0026] Mold body 1;

[0027] Limit post 2, the bottom of the limit post 2 is fixedly connected to the top of the mold body 1;

[0028] Spraying mechanism 3, the outer wall of the spraying mechanism 3 is fixedly connected to the outer wall of the mold body 1 through a frame;

[0029] Collection mechanism 4, the top of the collection mechanism 4 is fixedly connected to the bottom of the mold body 1;

[0030] The spraying mechanism 3 includes a fixed frame 31, the inner wall of the fixed frame 31 is rotatably connected with a spray pipe 32, and is linearly arranged along the outer wall of the fixed frame 31. The inner wall of the fixed frame 31 is fixedly connected with a water inlet pipe 5. The outer wall of the fixed frame 31 is fixedly connected with a limit buckle 34, and is linearly arranged along the outer wall of the fixed frame 31. The outer wall of the spray pipe 32 is fixedly connected to the inner wall of the fixed frame 31 through a connecting pipe 37. The connecting pipe 37 penetrates the cavity between the fixed frame 31 and the spray pipe 32. The inner wall of the fixed frame 31 is fixedly connected with a tension spring 39. The bottom of the fixed frame 31 is fixedly connected to the top of the collection mechanism 4. The inner wall of the collection mechanism 4 is fixedly connected with a water outlet pipe 6.

[0031] One end of the tension spring 39 away from the fixed frame 31 is fixedly connected to the outer wall of the spray pipe 32. A fixed block 38 is fixedly connected to the inner wall of the fixed frame 31. The outer wall of the fixed block 38 is in contact with the outer wall of the connecting pipe 37. By pressing the connecting pipe 37 with the two fixed blocks 38, the paint cannot pass through the connecting pipe 37. The outer wall of the limit buckle 34 is clamped with the inner wall of the spray pipe 32. An annular spray groove 36 is formed in the wall of the spray pipe 32 and is linearly arranged along the central axis of the spray pipe 32.

[0032] The collecting mechanism 4 includes a collecting frame 41. A slide rail 44 is fixedly connected to the inner wall of the collecting frame 41. A filter plate 42 is slidably connected to the inner wall of the collecting frame 41 through an installation groove 46. The opening of the installation groove 46 is larger than the outer shape of the filter plate 42, so that after the filter plate 42 is pulled out, the impurities on the filter plate 42 can be synchronously pulled out. A handle 45 is fixedly connected to the outer wall of the filter plate 42. The outer wall of the filter plate 42 is slidably connected to the inner wall of the slide rail 44. A filter groove 43 is formed in the wall of the filter plate 42 and is linearly arranged along the outer wall of the filter plate 42. The inner wall of the collecting frame 41 is fixedly connected to the outer wall of the water outlet pipe 6.

[0033] Working principle:

[0034] During use, first install the limit post 2 on the mold body 1 so that the mold body 1 can work normally. Then install the spraying mechanism 3 and the collecting mechanism 4 on the mold body 1. Before the mold body 1 works normally, the paint needs to be poured into the spraying mechanism 3 through the water inlet pipe 5. The paint is then sprayed into the mold body 1 through the spraying mechanism 3. When the spraying mechanism 3 is spraying, the excess paint slides along the outer wall of the mold body 1 and flows into the collecting mechanism 4 in the spraying mechanism 3. The collecting mechanism 4 collects the excess paint. When the paint in the collecting mechanism 4 covers the water outlet pipe 6, the paint can flow out of the collecting mechanism 4 through the water outlet pipe 6, so that the paint can be centrally processed.

[0035] Before the spraying mechanism 3 sprays the mold body 1, first pour the coating into the fixed frame 31 through the water inlet pipe 5 on the fixed frame 31 to fill the fixed frame 31 with the coating. The spray pipes 32 are linearly arranged on the fixed frame 31. Therefore, when spraying is required, only manually move the limit buckle 34 away from the fixed frame 31 to make the top of the limit buckle 34 slide out of the groove at the top of the spray pipe 32, so that the limit buckle 34 releases the fixation of the spray pipe 32. The spray pipe 32 is connected to the fixed frame 31 through a tension spring 39. Therefore, under the elastic action of the tension spring 39, the tension spring 39 pulls the spray pipe 32 to rotate upward. When the spray pipe 32 rotates upward, the pressing state of the connecting pipe 37 between the two fixed blocks 38 is released, so that the coating in the fixed frame 31 can enter the spray pipe 32 through the connecting pipe 37. An annular spray groove 36 is formed in the wall of the spray pipe 32. When the coating is continuously injected through the water inlet pipe 5, the coating is sprayed out of the spray pipe 32 through the annular spray groove 36, and then the surface of the mold body 1 is sprayed. And because of the annular opening of the annular spray groove 36, the spraying angle of the coating is fan-shaped, thus increasing the coverage area of the coating on the mold body 1.

[0036] When using the spraying mechanism 3, the fixed-point spraying of different positions can be realized by changing the rotation of the spray pipes 32 on the fixed frame 31. Just rotate the spray pipes 32 in the area to be sprayed upward and rotate the spray pipes 32 in the area not to be sprayed downward, so that the spray pipes 32 and the fixed blocks 38 on the fixed frame 31 approach each other and press the connecting pipe 37. After the connecting pipe 37 is pressed, the coating cannot enter the spray pipe 32 through the connecting pipe 37. Therefore, the downward-rotated spray pipe 32 cannot perform the spraying work. Then buckle the limit buckle 34 into the groove of the spray pipe 32 to fix the spray pipe 32.

[0037] During the spraying operation, the excess paint mixes with the impurities on the mold body 1 to form a mixed liquid. The mixed liquid slides along the outer wall of the mold body 1 and slides down into the collection mechanism 4. In the collection mechanism 4, the incoming mixed liquid is filtered and collected. The mixed liquid slides into the collection frame 41 along the outer wall of the mold body 1 and first contacts the filter plate 42. After being filtered by the filter slots 43 on the filter plate 42, the impurities larger than the filter slots 43 remain on the filter plate 42, while the fluid smaller than the filter plate 42 falls to the bottom of the collection frame 41. After the filter plate 42 is blocked after long-term use in the collection mechanism 4, the filter plate 42 is pulled out of the collection frame 41 by manually pulling the handle 45. When the filter plate 42 is pulled out of the collection frame 41, clean water is poured onto the mold body 1, causing the clean water to rush into the collection frame 41 to wash the impurities in the collection frame 41. The sewage from the washing flows out of the collection frame 41 through the water outlet pipe 6. Then, a new filter plate 42 is slid into the collection frame 41 along the installation groove 46 on the collection frame 41. There is a slide rail 44 fixed in the collection frame 41. By sliding the filter plate 42 in the slide rail 44, the position of the filter plate 42 is restricted. When the filter plate 42 is completely slid into the collection frame 41, the installation of the filter plate 42 is completed, and the collection work can be carried out again.
