Conventional pouring processes use molten steel directly through a single pouring cup, leading to prolonged overheating at the pouring cup and the potential for casting defects such as sandblasting, cracks, sand sticking, and air holes. Utility Model Content

[0003] The purpose of the utility model is to provide a bridge pouring device for a railway freight car bolster, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a bridge pouring device for a railway freight car bolster, comprising a bridge pouring cup, a bridge sprue, a bridge cross pouring gate, a bridge bracket, a lifting ring, a bridge sprue A, a casting pouring cup, a blind riser, an exhaust port, a bridge runner device, a straight pouring gate, an inner pouring gate, a sand box, and a mold forming channel. The bridge pouring cup, the bridge sprue, the bridge cross pouring gate, and the bridge pouring gate A of the bridge runner device are pre-embedded in the molding sand, and the upper and lower ends of the bridge cross pouring gate are welded with lifting rings and a bridge bracket, and the bridge sprue A is arranged above the casting pouring cup.

[0005] Preferably, the bridge gate cup is connected to an external blower to blow away the floating sand in the bridge gate and make it unobstructed.

[0006] Preferably, the bridge sprue A is arranged vertically below the casting sprue cup.

[0007] Preferably, there are two bridge sprues A in the left and right directions.

[0008] Compared with the prior art, the beneficial effects of the present invention are: the application benefits of the bridge runner device are: the bridge horizontal gate realizes a smooth flow of pouring liquid and reduces sand holes and air holes; the bridge straight gate is arranged above the casting gate cup, and supplies pouring molten iron in two directions, shortening the overheating time of the gate part, making the cooling speed of various parts of the casting tend to be uniform, reducing the tendency of cracks, and effectively improving the internal and surface quality of the casting blank.

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely explained below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] like Figure 1-Figure 3 As shown, a bridge pouring device for a railway freight car bolster includes a bridge pouring cup 1, a bridge sprue 2, a bridge cross pouring gate 3, a bridge bracket 4, a lifting ring 5, a bridge sprue A6, a casting sprue cup 7, a blind riser 8, an exhaust port 9, a bridge runner device 10, a straight pouring gate 11, an inner pouring gate 12, a sand box 13, and a mold forming channel 14. The sand box 13 is equipped with a mold forming channel 14. Casting pouring cups 7 are arranged on both sides of the sand box 13. The casting pouring cups 7 are connected to the straight pouring gate 11 and the inner pouring gate 12. The bridge pouring cup 1, the bridge sprue 2, the bridge cross pouring gate 3 and the bridge sprue A6 of the bridge runner device 10 are embedded in the molding sand. The upper and lower ends of the bridge cross pouring gate 3 are respectively welded with a lifting ring 5 and a bridge bracket 4. The bridge sprue A6 is arranged above the casting pouring cup 7. The sand box 13 is equipped with a blind riser 8 and an exhaust port 9.

[0015] The bridge gate cup 1 is connected to an external blower to blow away the floating sand in the bridge runner, and the bridge runner 2 realizes a smooth pouring liquid flow and reduces sand holes and air holes.

[0016] The bridge sprue A6 is arranged vertically below the casting pouring cup 7, and supplies molten iron in two directions, shortening the overheating time of the pouring part, making the cooling speed of each part of the casting uniform, and reducing the tendency of cracks.
