[0002] As Figure 1 shown, in an existing casting mold for a box-type substation grounding conductor, feeding is performed through a feeding port 6 at the top of the product. There is serious gas shielding in the deep cavity position of the product, sweating at the top, insufficient feeding, too high temperature at the junction of the root of the riser pipe 7 and the product, the riser is slender, and serious shrinkage cracks occur at the root when the product is demolded. At the same time, oxide skins and slag in the molten aluminum are easily directly introduced into the product, and there is no slag shielding effect during feeding.

[0003] The feeding port 6 and the riser pipe 7 are very close to each other, and the distance between the connecting rods is short, which is inconvenient for workers to pour molten aluminum; the total height of the mold is too high, the theoretical height is 785.6 MM, and large machines must be used during production to meet the requirements of mold opening, resulting in low production efficiency and long production cycle.

The upper runner and the lower runner are closed to form a feeding port, and the feeding port is communicated with the cavity; a riser pipe communicated with the cavity is provided on the upper mold core, and a sweating hole communicated with the cavity is provided on the lower mold core.

[0007] Preferably, an upper mold foot is provided on the upper mold core, and an upper mold pressing plate is provided on the upper mold foot. A ejector plate is provided between the two upper mold feet, ejector rods are provided on the ejector plate, and the riser pipe slidably penetrates through the ejector plate. A lower mold pressing plate is provided on the lower mold core.

[0008] The beneficial effect of the utility model is:

[0009] The casting mold for a box-type substation grounding conductor provided by the utility model, on the basis of the existing technology, reverses the upper and lower molds, so that the deep cavity position faces the lower mold and there will be no gas shielding; the feeding method is side-wall thin and flat feeding, which is convenient for workers to pour molten aluminum and has a good slag shielding effect.
