Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts casting, in particular to a pouring device for automobile parts casting. Background Art

[0002] Automotive parts casting is a key production link in the automotive manufacturing industry, involving the use of casting technology to produce various metal parts of automobiles. Casting is a manufacturing method that heats metal to a molten state, then pours the liquid metal into a pre-prepared mold, cools it and solidifies it, and finally forms parts of the desired shape. In the automotive industry, casting is mainly used to produce parts with complex shapes that are difficult to produce through other processing methods, or parts that need to have specific physical properties.

[0003] The patent with the patent authorization announcement number CN218252884U discloses a pouring device for casting automobile parts, including an outer barrel and a pouring bucket. The inner wall of the outer barrel is fixedly installed with a heat insulation layer, and the inner liner barrel is fixedly installed inside the outer barrel. The inner liner barrel is made of tungsten steel. An installation groove is formed between the inner liner barrel and the heat insulation layer, and a resistance wire is fixedly installed in a ring shape inside the installation groove. The outer wall of the bottom of the outer barrel is welded with a side plate. Although the above patent can heat and keep warm the molten metal inside the lined barrel, thereby preventing the molten metal from cooling and solidifying, and facilitating long-term pouring and use, there are still some shortcomings in actual use. For example, the pouring ports of molds of different specifications are of different sizes. The pouring ports of small-sized molds are relatively small, while the pouring ports of large-sized molds are larger. When pouring the molten metal into the mold, it is impossible to control the discharge amount of the pouring bucket according to the pouring requirements of molds of different specifications, which can easily lead to excessive discharge of molten metal when pouring small-sized molds, causing waste, or too little discharge of molten metal when pouring large-sized molds, resulting in a long time for filling.

[0004] Therefore, a pouring device for casting automobile parts is particularly needed to solve the problems existing in the prior art. Utility Model Content

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: A pouring device for casting automotive parts, refer to Figures 1 - 4 as shown, which includes a material storage cylinder 1, a mounting plate 2, a feeding pipe 3, a screw cap 4, a bellows 8, and a discharge pipe 9. The top of the material storage cylinder 1 is connected to the front and rear distributed mounting plates 2 by welding. The mounting plates 2 are provided with threaded holes. The upper right side of the upper part of the material storage cylinder 1 is connected to the feeding pipe 3 by welding. The upper end of the feeding pipe 3 is threadedly connected to the screw cap 4. The center position at the bottom of the material storage cylinder 1 is connected to the bellows 8, and the end of the bellows 8 is connected to the discharge pipe 9. The material storage cylinder 1, the bellows 8, and the discharge pipe 9 are all made of heat-insulating metal materials. It further includes a metering mechanism, and a metering mechanism for controlling the discharge amount of the molten metal is provided on the discharge pipe 9.

[0021] Refer to Figure 3 and Figure 4As shown in the figure, the metering mechanism includes a cylinder 10, a lifting frame 11, a first rotating rod 12, a first baffle plate 14, a guide rod 19, a second baffle plate 18, a connecting frame 16 and a second rotating rod 17. The upper right side of the discharge pipe 9 is connected with the cylinder 10 by bolts. The discharge pipe 9 is provided with first sliding grooves 13 distributed left and right. A lifting frame 11 is slidably connected between the two first sliding grooves 13. The telescopic rod of the cylinder 10 is fixedly connected with the lifting frame 11. The first rotating rods 12 are rotatably connected to both the left and right sides of the lifting frame 11. The discharge pipe 9 is provided with a plurality of second sliding grooves 15 distributed front and back. A first baffle plate 14 is slidably connected between two longitudinally aligned second sliding grooves 15. The two first baffle plates 14 are in contact with each other, blocking the discharge pipe 9. The first rotating rod 12 is rotatably connected to the first baffle plate 14. The lower part of the discharge pipe 9 is slidably connected with guide rods 19 distributed front and back. The second baffle plate 18 is connected to the guide rod 19 by welding. The two second baffle plates 18 are in contact with each other and are located below the first baffle plate 14. The left first baffle plate 14 is connected with the connecting frame 16 by welding. A second rotating rod 17 is connected between the connecting frame 16 and the second baffle plate 18. By controlling the telescopic rod of the cylinder 10 to extend or retract, the lifting frame 11 is driven to move downward or upward, so as to push or pull the first rotating rod 12 to rotate or reverse. The first rotating rod 12 pulls or pushes the first baffle plate 14 to move outward or inward. Then, the left first baffle plate 14 drives the connecting frame 16 to move left or right, causing the second rotating rod 17 to rotate or push the second baffle plate 18 to move outward or inward.

[0022] Referring to Figure 2 As shown in the figure, it further includes a motor 5, a stirring rod 6 and a heating ring 7. The upper part of the storage barrel 1 is connected with the motor 5 by bolts. A protective shell is provided at the top of the storage barrel 1. The motor 5 is below the protective shell. The output shaft of the motor 5 is connected with the stirring rod 6 through a coupling. The stirring rod 6 is located inside the storage barrel 1. The heating ring 7 is connected to the inside of the storage barrel 1 by bolts. The heating ring 7 is close to the inner wall of the storage barrel 1 and covers the stirring rod 6.

[0023] When the device is needed, the staff first places the storage barrel 1 on a suitable position on the ceiling above the workbench, uses a tool to connect the connector to the mounting plate 2 to fix the storage barrel 1, then rotates the screw cap 4 upward to open the discharge pipe 3, and pours the molten metal from the discharge pipe 3 into the storage barrel 1. After pouring, rotate the screw cap 4 downward to close the discharge pipe 3, and then turn on the heating ring 7 and the motor 5. The heating ring 7 runs to heat the molten metal to prevent the molten metal from solidifying. At the same time, the output shaft of the motor 5 drives the stirring rod 6 to rotate and stir the metal. The liquid increases the fluidity of the molten metal and further prevents the molten metal from solidifying. Then the staff puts the mold to be poured on the workbench, bends the bellows 8 to align the discharge pipe 9 with the injection port of the mold, and then turns on the cylinder 10 to control the telescopic rod of the cylinder 10 to extend and drive the lifting frame 11 to move downward. The lifting frame 11 pushes the first rotating rod 12 to rotate, and the first rotating rod 12 pulls the first baffle plate 14 to move outward. At this time, the first baffle plate 14 on the left side drives the connecting frame 16 to move to the left, so that the connecting frame 16 pushes the second rotating rod 17 to rotate. The second rotating rod 17 pushes the second baffle plate 18 to move outward, so as to achieve the effect of controlling the discharge amount of the discharge pipe 9 from the left and right directions and the front and back directions, so as to meet the casting requirements of molds of different specifications. When the telescopic rod of the cylinder 10 is extended to a suitable length, the first baffle plate 14 and the second baffle plate 18 are moved outward to a suitable position, and then the cylinder 10 is closed. At this time, the molten metal in the bellows 8 flows out from the discharge pipe 9 and is injected into the mold. After the mold is filled with the molten metal, the cylinder 10 is immediately opened and its telescopic rod is controlled to retract. The telescopic rod of the cylinder 10 drives the lifting frame 11 Moving upward, the lifting frame 11 pulls the first rotating rod 12 to reverse, and the first rotating rod 12 pushes the first baffle plate 14 to move inward. At this time, the first baffle plate 14 on the left side drives the connecting frame 16 to move right, so that the connecting frame 16 pulls the second rotating rod 17 to reverse, and the second rotating rod 17 pulls the second baffle plate 18 to move inward. When the telescopic rod of the cylinder 10 retracts to the initial state, the first baffle plate 14 and the second baffle plate 18 move inward and reset, the cylinder 10 can be closed, and the above steps are repeated to pour molten metal into the next mold.
