[0001] The utility model relates to the technical field of aluminum ingot melting, in particular to an ingot mold vibration device and an aluminum ingot melting equipment. Background Art

[0002] In the process of producing aluminum products, a lot of fragmented scraps will be generated. In order to improve the resource utilization rate, some manufacturers in the industry specifically recycle such scraps, melt them into aluminum liquid by melting process, and formulate the aluminum liquid according to the formula to produce aluminum ingots that meet the requirements of corresponding product standards. The operation process is as follows: Put the fragmented scraps into the melting furnace, the melting furnace melts the scraps into aluminum liquid, the operator formulates the aluminum liquid according to the formula corresponding to the product standard requirements, pours the formulated aluminum liquid into the aluminum ingot mold for cooling to form aluminum ingots, and then uses the aluminum ingot demolding mechanism to strike the aluminum ingot mold to make the aluminum ingots in the mold break away from the mold, so as to obtain aluminum ingots that meet the requirements of product standards. The existing aluminum ingot molds all statically cool and solidify the aluminum liquid. In the initial stage of cooling and solidification of the aluminum liquid, dendrites or coarse grains may grow rapidly in some crystal directions, resulting in the crystal structure of the finally solidified aluminum ingot not meeting the requirements. Summary of the Invention

[0003] The purpose of the utility model is to provide an ingot mold vibration device and an aluminum ingot melting equipment including the ingot mold vibration device. The ingot mold vibration device can make the aluminum ingots formed by cooling and solidification meet the corresponding crystal structure requirements, and improve the service life of the ingot mold vibration device on the premise of lower cost.

[0004] To achieve the above purpose, the utility model provides an ingot mold vibration device, which includes an aluminum ingot mold and a vibration mechanism. The vibration mechanism includes a cross bar and a first driving device. During the process of the aluminum ingot mold cooling the aluminum liquid into ingots, the first driving device drives the cross bar to strike the aluminum ingot mold containing the aluminum liquid that has not been cooled into ingots to make it vibrate; the first driving device is located at one end of the cross bar away from the aluminum ingot mold, and the length of the cross bar is set according to the distance between the aluminum ingot mold and the normal temperature environment position, and the first driving device is arranged at the normal temperature environment position.

[0005] Further, the vibration mechanism includes a cross bar and a first driving device, and the first driving device drives the cross bar to strike the aluminum ingot mold to make it vibrate.

[0006] Further, the vibration mechanism includes a support, and the first driving device drives the cross bar to rotate around the support so as to strike the aluminum ingot mold to make it vibrate.

[0007] Further, the first driving device is hinged to one end of the cross bar away from the aluminum ingot mold through a connecting rod, so as to drive the cross bar to rotate around the support through the connecting rod.

[0008] Further, the cross bar is located on one side of the aluminum ingot mold, and specifically, it impacts one side of the aluminum ingot mold to make it vibrate.

[0009] Further, it includes a conveyor belt. There are multiple aluminum ingot molds, and each aluminum ingot mold is arranged at equal intervals on the conveyor belt. The conveyor belt successively conveys each aluminum ingot mold to the vibration mechanism, and the vibration mechanism makes the conveyed aluminum ingot mold vibrate.

[0010] Further, it includes a second driving device. A driving wheel and a driven wheel are installed at both ends of the conveyor belt. The second driving device is in transmission connection with the driving wheel, and the second driving device drives the driving wheel to rotate, thereby driving the conveyor belt and the driven wheel to rotate together.

[0011] The utility model also provides an aluminum ingot melting device, which includes a melting furnace and the ingot mold vibration device as described above. The melting furnace melts the aluminum material into aluminum liquid and then discharges the aluminum liquid into the aluminum ingot mold of the ingot mold vibration device for cooling into ingots.

[0012] Further, it includes a demolding mechanism, and the demolding mechanism demolds the aluminum ingots formed by cooling in the aluminum ingot mold.

[0013] The ingot mold vibration device provided by the utility model includes a vibration mechanism. In the first aspect, the vibration mechanism makes the aluminum ingot mold containing the aluminum liquid that has not yet cooled into ingots vibrate, so that the aluminum liquid vibrates during the cooling process into ingots. The dendrites or coarse crystals formed in the initial stage of solidification will be damaged by the vibration, making the crystallization of the aluminum ingot finer and the range of looseness smaller, meeting the required crystal structure requirements. In the second aspect, the temperature of the aluminum ingot melting environment is very high (the environment where the melting furnace and the aluminum ingot mold are located is called the aluminum ingot melting environment). Ordinary electrical equipment is difficult to adapt to this high-temperature environment and special high-temperature-resistant electrical equipment needs to be used. High-temperature-resistant electrical equipment usually has a relatively high cost. Therefore, the utility model designs the vibration mechanism with reference to the seesaw structure, makes the cross bar longer, and sets the electrical equipment - the first driving device at a place far away from the aluminum ingot mold, that is, away from the aluminum ingot melting environment. In this way, the first driving device will not be in a high-temperature environment, and no special design is required. As long as the cross bar is designed to be longer, the service life of the first driving device will not be reduced, and the service life of the first driving device can be ensured at a relatively low cost, improving the service life of the ingot mold vibration device.

[0016] The following further elaborates on the present inventive concept in conjunction with specific embodiments.

[0017] The aluminum ingot melting equipment includes a melting furnace (not shown) and an ingot mold vibration device as Figure 1 shown. After the melting furnace melts the aluminum material into molten aluminum, the molten aluminum is discharged through the molten aluminum outlet (not shown) at its bottom into each aluminum ingot mold of the ingot mold vibration device for cooling into ingots. As Figure 1 shown, the ingot mold vibration device includes a conveyor belt 10 and a plurality of aluminum ingot molds 11 arranged at uniform intervals on the conveyor belt 10. The ingot mold vibration device includes a conveyor motor 12 as a second driving device. The two ends of the conveyor belt 10 are provided with a driving wheel 13 and a driven wheel 14. The conveyor motor 12 is drivingly connected to the driving wheel 13. The conveyor motor 12 drives the driving wheel 13 to rotate, thereby driving the conveyor belt 10 and the driven wheel 14 to rotate together, so that the conveyor belt 10 conveys each aluminum ingot mold. The molten aluminum outlet of the melting furnace is arranged directly above the rear end of the conveyor belt 10. The conveyor belt 10 successively conveys each aluminum ingot mold 11 to the lower part of the molten aluminum outlet of the melting furnace to receive the molten aluminum. The ingot mold vibration device further includes a vibration mechanism located on the right side in the middle of the conveyor belt 10. The vibration mechanism includes a support 23 and a cross bar 20 pivotally connected to the middle of the support 23. It also includes a telescopic motor 21 as a first driving device. The end of the telescopic rod of the telescopic motor 21 is hinged to one end of the cross bar 20 far from the aluminum ingot mold 11 through a connecting rod 22. Specifically, the end of the telescopic rod of the telescopic motor 21 is hinged to the lower end of the connecting rod 22, and the upper end of the connecting rod 22 is hinged to the right end of the cross bar 20. In this embodiment, each aluminum ingot mold filled with molten aluminum continues to move forward under the drive of the conveyor belt 10. The conveyor belt 10 successively conveys each aluminum ingot mold 11 filled with molten aluminum that has been cooled into ingots above to the vertical plane where the cross bar 20 is located (this position is denoted as the impact station). The telescopic motor 21 drives the cross bar 20 to impact the aluminum ingot mold 11 sent to the impact station to make it vibrate. The impact process is as follows:

[0018] As Figure 1As shown in the figure, during the process of cooling molten aluminum into ingots in each aluminum ingot mold 11, the conveyor belt 10 conveys an aluminum ingot mold 11 containing molten aluminum that has not yet cooled into an ingot to the impact station. The telescopic motor 21 retracts the telescopic rod downward, driving the connecting rod 22 to move downward, thereby driving the right end of the crossbar 20 to move downward. Since the middle of the crossbar 20 is pivotally connected to the support 23, the right end of the crossbar 20 rotates downward around the support 23 and the left end rotates upward around the support 23. The right side of the aluminum ingot mold 11 is located on the rotation path of the left end of the crossbar 20. The telescopic motor 21 drives the left end of the crossbar 20 to rotate upward until it impacts the right side of the aluminum ingot mold 11 containing molten aluminum that has not yet cooled into an ingot, causing the aluminum ingot mold 11 to vibrate, so that the molten aluminum vibrates during the process of cooling into an ingot. The dendrites or coarse grains formed in the initial solidification stage will be damaged by the vibration, making the crystal grains of the aluminum ingot finer and the loose range smaller, meeting the required crystal structure requirements. In this embodiment, both sides of the aluminum ingot mold 11 are fixed on the conveyor belt 10 and will be restricted by the conveyor belt 10 when being impacted, so as to avoid excessive vibration amplitude caused by the impact and ensure a moderate vibration amplitude. Then the telescopic motor 21 changes to extend the telescopic rod upward, driving the connecting rod 22 to move upward, thereby driving the right end of the crossbar 20 to rotate upward around the support 23 and the left end of the crossbar 20 to rotate downward around the support 23, and the left end of the crossbar 20 leaves the impacted aluminum ingot mold 11. During this process, the conveyor belt 10 continues to convey the next aluminum ingot mold 11 containing molten aluminum that has not yet cooled into an ingot to the impact station. The telescopic motor 21 retracts the telescopic rod downward again, driving the connecting rod 22 to move downward, thereby driving the right end of the crossbar 20 to rotate downward around the support 23 and the left end to rotate upward around the support 23 until it impacts the right side of the aluminum ingot mold 11, causing the aluminum ingot mold 11 to vibrate, so that the molten aluminum vibrates during the process of cooling into an ingot. The dendrites or coarse grains formed in the initial solidification stage will be damaged by the vibration, making the crystal grains of the aluminum ingot finer and the loose range smaller, meeting the required crystal structure requirements. Then the telescopic motor 21 changes to extend the telescopic rod upward, driving the connecting rod 22 to move upward, thereby driving the right end of the crossbar 20 to rotate upward around the support 23 and the left end of the crossbar 20 to rotate downward around the support 23, and the left end of the crossbar 20 leaves the impacted aluminum ingot mold 11. The telescopic motor 21 impacts each aluminum ingot mold 11 containing molten aluminum that has not yet cooled into an ingot in sequence according to the above process to make it vibrate, so that the molten aluminum vibrates during the process of cooling into an ingot. The dendrites or coarse grains formed in the initial solidification stage will be damaged by the vibration, making the crystal grains of the aluminum ingot finer and the loose range smaller, meeting the required crystal structure requirements.

[0019] The ambient temperature of aluminum ingot melting is very high (the environment where the melting furnace and the aluminum ingot mold 11 are located is called the aluminum ingot melting environment). Electrical equipment needs to be specially designed to adapt to this high-temperature environment, otherwise its service life will be greatly reduced. However, special design of electrical equipment requires high costs. Therefore, in this embodiment, the vibration mechanism is designed with reference to the seesaw structure. The crossbar 20 is designed to be longer, and the electrical equipment, the telescopic motor 21, is arranged at a place far from the aluminum ingot mold 11, that is, away from the aluminum ingot melting environment. In this way, the telescopic motor 21 will not be in a high-temperature environment and does not need to be specially designed. As long as the crossbar 20 is designed to be longer, the service life of the telescopic motor 21 will not be reduced, and the service life of the telescopic motor 21 can be ensured at a relatively low cost.

[0020] The aluminum ingot melting equipment further includes a demoulding mechanism (not shown) provided at the front end of the ingot mold vibration device. The demoulding mechanism includes a hammer and a cylinder. After the aluminum ingot mold is impacted by the crossbar 20, it continues to move forward to the front end of the conveyor belt 10 driven by the conveyor belt 10. At this time, the aluminum liquid in the aluminum ingot mold 11 has cooled to form an aluminum ingot. The cylinder of the demoulding mechanism drives the hammer to strike the aluminum ingot mold 11 that has moved to the front end of the conveyor belt 10, so that the aluminum ingot formed by internal cooling no longer fits tightly against the inner side wall of the aluminum ingot mold 11 and can be separated from the aluminum ingot mold 11 to achieve demoulding.

[0021] As described above is only the implementation manner of the present invention, and the scope of patent protection is not limited thereby. Those skilled in the art make non-substantive changes or substitutions based on the present invention and still fall within the scope of patent protection.
