[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] See Figure 1-8 .

[0021] The utility model discloses a pouring device for a fairing, which comprises a pouring gate mold 1, a runner with sand core mold 2 and a main body mold 3. The opening of the main body mold faces upward, and the inner part of the main body mold is consistent with the outer contour of the fairing. The upper part of the runner with sand core mold is a rectangular plate mechanism, and a module 4 consistent with the inner contour of the fairing is arranged on the lower side of the runner with sand core mold. The module 4 of the runner with sand core mold is inserted into the main body mold to form a pouring mold groove. There is a runner 5 in the shape of "day" above the runner with sand core mold. A plurality of first pouring grooves 6 are evenly arranged below the runner. The first pouring grooves are located outside the module and communicate with the pouring mold groove. A pouring gate mold 1 is covered above the runner with sand core mold, and the pouring gate mold is provided with a pouring gate 7.

[0022] The main body mold is divided into two parts, namely a left main body mold 31 and a right main body mold 32. The cross-section of the bottom of the right main body mold is an acute angle. A side groove 8 is arranged at the splicing end of the left main body mold and the right main body mold, and a side convex block 9 is arranged at the corresponding position of the right main body mold. Lateral connecting blocks 10 are arranged on the side bodies of the left main body mold and the right main body mold. The side convex block is inserted into the side groove, and bolts are driven into the two lateral connecting blocks for fixation.

[0023] Horizontal convex blocks 11 are arranged at the bottom near the edge of the pouring gate mold and the runner with sand core mold. Horizontal grooves 12 are arranged above the main body mold and the runner with sand core mold. Bolt holes 13 are arranged on both sides of the pouring gate mold, the runner with sand core mold and the main body mold. The horizontal convex blocks are inserted into the horizontal grooves in sequence, and then bolts are driven into the bolt holes on both sides for fixation.

[0024] A second pouring groove 14 is arranged on one side of the right main body mold away from the left main body mold. The cross-section of the second pouring groove is in the shape of a water droplet. The main body of the second pouring groove is parallel to the side of the right main body mold. A pouring inclined port 15 with a consistent width is arranged between the second pouring groove and the side of the right main body mold. A side pouring groove 16 with a shape matching that of the second pouring groove is arranged at the corresponding position of the runner of the runner with sand core mold and the second pouring groove. As Figure 2 shown, the pouring of the fairing by this device is a pouring method with the acute angle facing downward and lying flat. When the fairing is laid flat, one side below the fairing is in the shape of an acute angle. If the second pouring groove and the side pouring groove 16 are not provided, during the pouring process, the liquid metal will have a certain liquid tension, so it is very difficult to fill the acute angle. Even if it may be filled, it is very slow, and there will be a situation where it is not filled when the metal solidifies. Therefore, the side pouring groove 16 is arranged along the acute angle inclined plane, and a second pouring groove with a larger aperture is set so that the side angle can be poured synchronously, reducing the situation where the pouring mold groove is not filled completely.

[0025] The bottom of the main mold has multiple through-holes 17 evenly distributed. The function of the through-holes 17 is to squeeze out the air in the casting mold groove during casting, so as to form an internal gas pocket.

[0026] Specific assembly operations

[0027] First, the left main body mold 31 is spliced ​​onto the horizontal runner sand core mold 2. Then, the right main body mold 32 is inserted from the acute end of module 4 and inserted obliquely along the slope to splice with the left main body mold 31 and the horizontal runner sand core mold 2. The two sets of lateral connecting blocks 10 on both sides are fixed with bolts. Then, the sprue mold 1 is spliced ​​on top of the horizontal runner sand core mold 2. Bolts are driven into the bolt holes on both sides to complete the installation. The device can then be fixed to the external fixing device for pouring.
