Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology, specifically to a splash-proof lost foam casting hammer pouring device. Background Technology

[0002] Lost foam casting is a casting process that uses lost foam to cast workpieces. The mold to be cast is made of polymer materials such as foam plastic. The lost foam is buried in dry quartz sand and the casting box is filled with vibration. Molten metal is poured into the casting box under negative pressure, causing the foam plastic model to be heated and vaporized, and the liquid metal to replace the position of the lost foam. After the liquid metal cools and solidifies, the workpiece to be cast can be obtained.

[0003] The hammerhead is also manufactured by lost foam casting. When molten metal is filled into the hammerhead mold of molding sand through the feeding component and the pouring bucket, the pouring bucket needs to be tilted continuously. This means that the pouring bucket and the feeding component need to be aligned accurately when the pouring bucket is first tilted to prevent molten metal from splashing into the external environment and damaging the surrounding equipment or personnel.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a splash-proof lost foam casting hammer pouring device, including a sand box 1 and a pouring bucket 2. A guide plate 3 is fixedly installed on the side of the pouring bucket 2. A V-groove 4 is provided on the surface of the guide plate 3. The pouring bucket 2 is movably installed on one side of the sand box 1 through a tilting mechanism. A connecting frame 5 is installed on the inner wall of the sand box 1. A feed pipe 6 is fixedly installed on the connecting frame 5. A splash guard 7 is fixedly installed on the top of the feed pipe 6. A baffle 8 is vertically slidably connected inside the splash guard 7. The baffle 8 is always located above the guide plate 3. One end of the guide plate 3 extends into the interior of the splash guard 7. A traction mechanism is provided between the baffle 8 and the sand box 1. The traction mechanism is connected in cooperation with the tilting mechanism.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The traction mechanism can drive the casting barrel 2 to rotate. When the casting barrel 2 rotates, it can drive the guide plate 3 to rotate synchronously, so that the molten metal inside the casting barrel 2 can enter the feed pipe 6 through the V-groove 4 and the guide plate 3. During this process, the splash guard 7 can prevent the molten metal from splashing. Since the casting barrel 2 is rotating, the guide plate 3 can revolve under the drive of the casting barrel 2. Therefore, one end of the guide plate 3 will gradually approach the inner wall of the splash guard 7. At this time, the molten metal may directly contact the inner wall of the splash guard 7. Therefore, the overall height of the splash guard 7 must be high enough to meet the vertical displacement of the guide plate 3 during the tilting process of the casting barrel 2.

[0025] The tilting mechanism includes a base plate 9, upright plates 10, rotating shafts 11, and a hydraulic cylinder 12. The base plate 9 is fixedly installed on the side of the sand box 1. The two upright plates 10 are vertically fixedly installed on the surface of the base plate 9. The two rotating shafts 11 are symmetrically fixedly installed on both sides of the pouring barrel 2. The pouring barrel 2 is rotatably connected between the two upright plates 10 through the two rotating shafts 11. The bottom of the hydraulic cylinder 12 is hinged to the top of the base plate 9, and the output end of the hydraulic cylinder 12 is hinged to the bottom of the pouring barrel 2.

[0026] Please see Figure 2 The hydraulic cylinder 12 is connected to the control system and hydraulic circuit system in the background. When pouring, the hydraulic cylinder 12 is started and the hydraulic cylinder 12 extends, thereby driving the pouring barrel 2 to drive the rotating shaft 11 to rotate on the surface of the vertical plate 10, thereby realizing the pouring of the molten metal inside the pouring barrel 2.

[0027] The traction mechanism includes a bracket 13, guide rods 14, and a top plate 15. The top plate 15 is fixedly installed on the side of the sand box 1. Two guide rods 14 are vertically fixedly connected between the top plate 15 and the bottom plate 9. The bracket 13 is vertically slidably connected to the surface of the two guide rods 14. The baffle 8 is fixedly connected to the bracket 13. The bracket 13 is engaged with the rotating shaft 11 through a transmission structure. The transmission structure includes gear teeth 16 and a drive gear 17. The drive gear 17 is fixedly installed on the surface of the rotating shaft 11. Multiple gear teeth 16 are equidistantly fixedly installed on the surface of the bracket 13. The drive gear 17 meshes with the gear teeth 16.

[0028] Please see Figure 2 and Figure 4 As the casting barrel 2 drives the rotating shaft 11 to rotate, it can drive the drive gear 17 to rotate synchronously. When the casting barrel 2 tilts towards the sand box 1, the casting barrel 2 can drive the drive gear 17 to rotate counterclockwise through the rotating shaft 11. At this time, the drive gear 17 can drive the support 13 to move vertically downward through multiple gear teeth 16, thereby causing the support 13 to move down on the surface of the guide rod 14. At the same time, it drives the baffle 8 to move down inside the splash shield 7. Since the vertical height of the guide plate 3 gradually decreases during the rotation of the casting barrel 2, the continuously descending baffle 8 will always stay not far from the top of the guide plate 3, thus preventing molten metal from splashing.

[0029] A guide structure is provided on the top plate 15. The guide structure includes a side plate 18, a reinforcing rod 19 and rollers 20. The side plate 18 is vertically fixed to both sides of the top plate 15. The two rollers 20 are symmetrically rotated and connected to the surface of the side plate 18. The reinforcing rod 19 is inclined and fixed between the side plate 18 and the top plate 15. The surface of the rollers 20 is in contact with the inner wall of the bracket 13.

[0030] Please see Figure 4 and Figure 6During the movement, the bracket 13 can generate sliding friction on the surface of the roller 20. When the roller 20 is subjected to sliding friction, it will rotate on the surface of the side plate 18, thereby converting this part of the friction into rolling friction, so that the bracket 13 can move smoothly in the vertical direction. At the same time, the guide rod 14 and the roller 20 prevent the bracket 13 from displacing in the horizontal direction, thereby ensuring the precise meshing between the gear teeth 16 and the drive gear 17.

[0031] The splash guard 7 and the feed pipe 6 are connected by a funnel 21. The funnel 21 is fixedly connected between the splash guard 7 and the feed pipe 6. The baffle 8 is concentrically set with the splash guard 7, and a gap of 1cm-2cm is left between the side of the baffle 8 and the inner wall of the splash guard 7.

[0032] Please see Figure 1 and Figure 5 The funnel 21 is designed to collect the molten metal, allowing it to enter the feed pipe 6 normally. In this embodiment, a gap is left between the side of the baffle 8 and the inner wall of the splash guard 7 to prevent friction between the baffle 8 and the splash guard 7 from affecting the normal movement of the baffle 8.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
