Description

Technical Field

[0001] This utility model relates to the field of automotive steering knuckle casting technology, and in particular to an automotive steering knuckle casting equipment. Background Technology

[0002] The steering knuckle is a crucial component of the automotive steering axle. Its primary function is to transmit and bear the load from the front of the vehicle and support the front wheels as they rotate around the kingpin, thus enabling the vehicle's steering function. During vehicle operation, the steering knuckle is subjected to varying impact loads, therefore requiring high strength. Consequently, defects such as surface defects and internal sand inclusions in castings are unacceptable.

[0003] Currently, existing steering knuckle casting molds use risers to allow molten iron to flow into the mold cavity. This effectively reduces the probability of shrinkage porosity in the casting. However, this layout process can easily cause turbulent flow and sand erosion when pouring molten iron, resulting in sand and slag holes in the casting. This affects the appearance and internal quality of the casting, causing it to fail to meet standard requirements. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to propose an automobile steering knuckle casting equipment. The technical problem to be solved is that the existing steering knuckle casting mold adopts the method of molten iron flowing into the cavity through the riser in the process design. This layout process can easily cause turbulent flow of molten iron and sand washing when pouring molten iron, thereby forming sand slag holes in the casting and affecting the appearance and internal quality of the casting.

[0006] (II) Technical Solution

[0007] To achieve the above technical objectives, this utility model provides an automotive steering knuckle casting device:

[0008] It includes a pouring cup, the bottom of which is fixed and connected to a top-level horizontal runner. The end of the top-level horizontal runner away from the pouring cup is fixed and connected to a vertical runner. The bottom of the vertical runner is fixed and connected to a bottom-level horizontal runner. A first water inlet and a second water inlet are fixed and connected to the vertical runner. A third water inlet is fixed and connected to the bottom-level horizontal runner. The end of the first water inlet away from the vertical runner is fixed and connected to a first insulating riser. The ends of the second water inlet away from the vertical runner and the ends of the third water inlet away from the bottom-level horizontal runner are both fixed and connected to a second insulating riser. The first and second insulating risers are both fixed and connected to a casting cavity.

[0009] Preferably, the first water inlet channel is located above the second water inlet channel, and a filter chamber is fixed and connected to the vertical channel, the filter chamber being located above the junction of the first water inlet channel and the vertical channel.

[0010] Preferably, U-shaped plates are fixed to the inner walls of both sides of the filter chamber, and a rectangular frame is slidably connected to both U-shaped plates, with a filter screen fixed inside the rectangular frame.

[0011] Preferably, there is a gap between one side of the U-shaped plate and the rectangular frame and one side of the filter chamber, and a baffle is filled in the gap.

[0012] Preferably, both sides of the filter chamber are rotatably connected to a rotating shaft, and a rotating plate is fixed to one end of each rotating shaft that is far apart from the other. A connecting plate is fixed between the two rotating plates.

[0013] Preferably, the connecting plate is internally threaded with a screw, and one end of the screw is fixed with a pressure plate.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. The automotive steering knuckle casting equipment mainly uses bottom-feeding molten iron, and pours the molten iron into the mold cavity through a three-layer molten iron feeding method. This improves production efficiency, facilitates the adjustment of the water inlet speed by the flow rate of the three-layer gating system, and pours the molten iron layer by layer. This avoids the upper layer of molten iron from entering the mold cavity too early, which would cause sand washing and slag formation. At the same time, it also avoids the upper layer of molten iron from entering the mold cavity too early, which would cause cold shuts or shrinkage defects, and effectively improves the appearance and internal quality of the casting.

[0016] 2. When cleaning the filter screen, first rotate the screw to move the pressure plate. Once the pressure plate no longer touches the baffle, rotate the rotating plate to rotate the connecting plate, screw, and pressure plate until the pressure plate no longer obstructs the baffle. Then, remove the baffle from the gap and remove the U-shaped plate and filter screen from the filter chamber for cleaning. Next, place the rectangular frame inside the U-shaped plate and then place the baffle in the gap. Then, rotate the rotating plate and connecting plate in the opposite direction and rotate the screw to move the pressure plate, causing the pressure plate to press against the baffle. This fixes the baffle in the gap, sealing the filter screen in the filter chamber. This method facilitates installing or removing the filter screen from the filter chamber for cleaning.

[0022] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure.

[0023] Reference Figure 1-3 :

[0024] In one embodiment of this utility model, an automotive steering knuckle casting apparatus is provided, including a pouring cup 1. A top-level horizontal runner 2 is fixedly connected to the bottom of the pouring cup 1. A vertical runner 3 is fixedly connected to the end of the top-level horizontal runner 2 away from the pouring cup 1. A bottom-level horizontal runner 4 is fixedly connected to the bottom of the vertical runner 3. A first water inlet runner 5 and a second water inlet runner 6 are fixedly connected to the vertical runner 3. A third water inlet runner 7 is fixedly connected to the bottom-level horizontal runner 4. The first water inlet runner 5 is located away from the vertical runner 3. One end of the first insulated riser 8 is fixed and connected to the second water inlet sprue 6. The end of the second water inlet sprue 6 away from the vertical sprue 3 and the end of the third water inlet sprue 7 away from the bottom horizontal sprue 4 are both fixed and connected to the second insulated riser 9. The first insulated riser 8 and the second insulated riser 9 are both fixed and connected to the casting cavity 11. The first water inlet sprue 5 is located above the second water inlet sprue 6. The vertical sprue 3 is fixed and connected to the filter cavity 10. The filter cavity 10 is located above the junction of the first water inlet sprue 5 and the vertical sprue 3.

[0025] In use, molten iron is poured into the pouring cup 1, and then flows into the top horizontal runner 2 through the pouring cup 1. After that, the molten iron flows into the vertical runner 3 through the top horizontal runner 2, and then into the bottom horizontal runner 4 through the vertical runner 3. When the molten iron flows in the vertical runner 3 and the bottom horizontal runner 4, it will flow into the first water inlet runner 5, the second water inlet runner 6, and the third water inlet runner 7, and then into the first insulating riser 8 and the second insulating riser 9. Finally, the molten iron flows into the casting cavity 11 through the first insulating riser 8 and the second insulating riser 9. This automotive steering knuckle casting equipment mainly uses bottom-entry molten iron, and pours the molten iron into the cavity through a three-layer molten iron inlet method, which improves production efficiency, facilitates the adjustment of the water inlet speed by the three-layer runner flow rate, and pours layer by layer, avoiding the upper layer of molten iron from entering the cavity too early, which would cause sand washing and slag generation. At the same time, it also avoids the upper layer of molten iron from entering the cavity too early, which would cause cold shut or shrinkage defects, and effectively improves the appearance and internal quality of the casting.

[0026] The filter chamber 10 has U-shaped plates 21 fixed on both inner walls. A rectangular frame 12 is slidably connected to both U-shaped plates 21. A filter screen 13 is fixed inside the rectangular frame 12. A gap 14 is formed between one side of the U-shaped plates 21 and the rectangular frame 12 and one side of the filter chamber 10. A baffle 15 is filled in the gap 14. A rotating shaft 16 is rotatably connected to both sides of the filter chamber 10. A rotating plate 17 is fixed to the ends of the two rotating shafts 16 that are far apart from each other. A connecting plate 18 is fixed between the two rotating plates 17. A screw 19 is threaded into the connecting plate 18. A pressure plate 20 is fixed to one end of the screw 19.

[0027] In use, the molten iron injected into the casting cavity 11 can be filtered through the filter chamber 10 and its internal filter screen 13. When the filter screen 13 needs to be cleaned, first rotate the screw 19 to move the pressure plate 20. After the pressure plate 20 no longer abuts against the baffle 15, rotate the rotating plate 17 to rotate the connecting plate 18, screw 19, and pressure plate 20, so that the pressure plate 20 rotates until it no longer blocks the baffle 15, i.e., the position of the pressure plate 20 is as follows. Figure 3 Rotate to the middle position as follows Figure 2 At this point, the baffle 15 can be removed from the gap 14, and then the U-shaped plate 21 and filter screen 13 can be removed from the filter chamber 10. The filter screen 13 can then be cleaned. After placing the rectangular frame 12 into the U-shaped plate 21, the baffle 15 can be placed into the gap 14. Then, the rotating plate 17 and connecting plate 18 are rotated in the opposite direction to position the connecting plate 18 and pressure plate 20 as shown. Figure 2 Rotate the position in the middle to such Figure 3 Then rotate the screw 19 to move the pressure plate 20, so that the pressure plate 20 presses against the baffle 15, that is, the baffle 15 is fixed in the gap 14, so that the baffle 15 seals the filter screen 13 in the filter chamber 10. This method makes it easy to install the filter screen 13 in the filter chamber 10 or remove the filter screen 13 from the filter chamber 10 for cleaning.
