Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot cooling technology, and more specifically, to a rapid cooling device for aluminum ingot casting molds. Background Technology

[0002] Aluminum ingots are the basic semi-finished products in aluminum production. They are typically formed by pouring molten aluminum into a specific mold (casting mold) and then cooling and solidifying it into a standard block-shaped product. Aluminum ingots have advantages such as low density, light weight, good electrical and thermal conductivity, corrosion resistance, and ease of processing. They are one of the most commonly used metal materials in industry. As a bulk commodity, aluminum ingots are widely traded in the market and are the raw materials for subsequent processing into final products such as aluminum rods, aluminum plates, aluminum foil, and profiles. They are widely used in many fields such as aerospace, transportation, construction, packaging, and power electronics. During the casting of aluminum ingots, a cooling device is needed to cool and solidify the molten aluminum into a standard-shaped aluminum ingot.

[0003] For example, Chinese patent disclosure: A high-efficiency aluminum ingot production line aluminum ingot cooling device, application number: CN202123109089.X, which includes an aluminum ingot retention box installed on the aluminum ingot production and transportation line, multiple aluminum ingot retention boxes installed, each aluminum ingot retention box having a gap between them, an aluminum ingot retention groove opened in the aluminum ingot retention box, a cooling water passage hole opened in the lower part of the aluminum ingot retention box, and an aluminum ingot cooling box set in the lower area of ​​the aluminum ingot production and transportation line. This utility model has four water vapor auxiliary collection rods distributed in four different directions. The water vapor auxiliary collection rods can absorb water vapor in large quantities. The setting of the water vapor auxiliary collection rods allows the staff to observe the entire process of water cooling aluminum ingots without affecting the collection of water vapor, and does not affect the gap and maintenance.

[0004] However, the above technical solution uses the method of immersing the aluminum ingot holding box in cooling water for cooling. However, this method has certain limitations. The cooling water needs to transfer heat through the thickness of the mold wall, but due to the thermal resistance effect of the mold wall, the cooling speed will be limited to a certain extent, which limits the heat transfer efficiency and makes it difficult to further improve the cooling rate. Utility Model Content

[0005] The main purpose of this invention is to provide a rapid cooling device for aluminum ingot casting molds, which can effectively solve the problem of the method of immersing the aluminum ingot holding box in cooling water for cooling in the background art. However, this method has certain limitations. The cooling water needs to transfer heat through the thickness of the casting mold wall, but due to the thermal resistance effect of the casting mold wall, the cooling speed will be limited to a certain extent, which limits the heat transfer efficiency and makes it difficult to further improve the cooling rate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rapid cooling device for aluminum ingot casting molds, comprising an aluminum ingot production and transport line, a cooling water tank disposed on one side below the aluminum ingot production and transport line, a plurality of aluminum ingot retention boxes disposed on the aluminum ingot production and transport line, a casting groove disposed on the aluminum ingot retention box, a plurality of first grooves disposed on the inner wall of the casting groove, a first baffle slidably disposed in the first groove, a second groove disposed on the outer wall of the aluminum ingot retention box, a second baffle slidably disposed in the second groove, a first wedge block disposed on both sides of the outer wall surface of the second baffle, a plurality of sliding grooves disposed on both sides of the inner wall of the cooling water tank, a first spring fixedly installed in the sliding groove, and a second wedge block fixedly disposed on one side of the first spring.

[0007] Preferably, the first groove is connected to the second groove, the second groove is U-shaped, and the second wedge block slides in the groove.

[0008] Preferably, the second baffle includes a baffle base, on which two guide grooves are provided, and a guide slider is slidably disposed in the guide grooves. Two third grooves are provided on one side of the baffle base, and a second spring is fixedly installed in the third groove.

[0009] Preferably, the first baffle, the first wedge block and the baffle base are fixedly connected, and the guide groove and the guide slider are both T-shaped.

[0010] Preferably, the guide slider is fixedly connected to the aluminum ingot retention box, and the elastic force of the first spring is greater than that of the second spring.

[0011] Preferably, one side of the second spring is fixedly connected to the aluminum ingot retention box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When this utility model is used, the aluminum ingot holding box is transported to the cooling water tank through the aluminum ingot production and transportation line. The cooling water in the cooling water tank is used to cool the aluminum ingot in the casting tank. When the aluminum ingot holding box moves to the second half of the cooling water tank, the second wedge block contacts the first wedge block. Since the elastic force of the first spring is greater than that of the second spring, the first wedge block is blocked by the second wedge block and stays in place. This makes the baffle base and the first baffle unable to close the second groove and the first groove. Then the cooling water in the cooling water tank passes through the second groove and the first groove and directly contacts the blocked surface of the aluminum ingot in the casting tank, which accelerates the heat transfer speed and achieves a faster final cooling rate.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 3 As shown, a rapid cooling device for aluminum ingot casting molds includes an aluminum ingot production and transport line 1. A cooling water tank 2 is provided on one side below the aluminum ingot production and transport line 1. Several aluminum ingot retention boxes 3 are provided on the aluminum ingot production and transport line 1. A casting groove 4 is provided on the aluminum ingot retention box 3. Several first grooves 5 are provided on the inner wall of the casting groove 4. A first baffle 6 is slidably arranged in the first groove 5. A second groove 7 is provided on the outer wall of the aluminum ingot retention box 3. A second baffle 8 is slidably arranged in the second groove 7. First wedge blocks 9 are provided on both sides of the outer wall surface of the second baffle 8. Several sliding grooves 10 are provided on both sides of the inner wall of the cooling water tank 2. A first spring 11 is fixedly installed in the sliding groove 10. A second wedge block 12 is fixedly arranged on one side of the first spring 11.

[0021] like Figure 4As shown, in another embodiment of the present invention, the second baffle 8 includes a baffle base 801, two guide grooves 802 are provided on the baffle base 801, a guide slider 803 is slidably provided in the guide grooves 802, and two third grooves 804 are provided on one side of the baffle base 801, and a second spring 805 is fixedly installed in the third grooves 804.

[0022] When the second wedge block 12 contacts the first wedge block 9, the first wedge block 9 is blocked by the second wedge block 12 and remains stationary because the elastic force of the first spring 11 is greater than that of the second spring 805. The guide slider 803 moves with the aluminum ingot holding box 3, while the aluminum ingot production transport line 1 continues to move the aluminum ingot holding box 3. The baffle base 801 remains stationary with the first wedge block 9, the second spring 805 deforms, and the first baffle 6 remains stationary with the baffle base 801, so that the baffle base 801 and the first baffle 6 can no longer seal the second groove 7 and the first groove 5. Then the cooling water in the cooling water tank 2 passes through the second groove 7. The first groove 5 directly contacts the shielded surface of the aluminum ingot in the casting groove 4, accelerating the heat transfer speed and achieving a faster final cooling rate. As the aluminum ingot retention box 3 moves, the guide slider 803 eventually moves from one end of the guide groove 802 to the other end. Then, the guide slider 803 drives the baffle base 801 to move by pressing the inner wall of the guide groove 802. The baffle base 801 drives the first wedge block 9 to move. The first wedge block 9 presses the inclined surface of the second wedge block 12, causing the second wedge block 12 to enter the groove 10. The second wedge block 12 no longer obstructs the first wedge block 9, so that the second baffle 8 will not restrict the movement of the aluminum ingot retention box 3.

[0023] Working principle of this rapid cooling device for aluminum ingot casting:

[0024] In use, the aluminum ingot holding box 3 is transported to the cooling water tank 2 via the aluminum ingot production transport line 1. The cooling water in the cooling water tank 2 cools the aluminum ingots in the casting mold trough 4. When the aluminum ingot holding box 3 moves to the latter half of the cooling water tank 2, the second wedge block 12 contacts the first wedge block 9. Since the elastic force of the first spring 11 is greater than the elastic force of the second spring 805, the first wedge block 9 is blocked by the second wedge block 12 and stays in place. The guide slider 803 moves with the aluminum ingot holding box 3, and the aluminum ingot is produced... The production transport line 1 continues to move the aluminum ingot holding box 3. The baffle base 801 follows the first wedge block 9 and stays in place. The second spring 805 deforms, and the first baffle 6 follows the baffle base 801 and stays in place, so that the baffle base 801 and the first baffle 6 can no longer close the second groove 7 and the first groove 5. Then the cooling water in the cooling water tank 2 passes through the second groove 7 and the first groove 5 and comes into direct contact with the blocked surface of the aluminum ingot in the casting mold trough 4, which accelerates the heat transfer speed and achieves a faster final cooling rate.

[0025] As the aluminum ingot retention box 3 moves, the guide slider 803 eventually moves from one end of the guide groove 802 to the other end. Then, the guide slider 803 drives the baffle base 801 to move by pressing the inner wall of the guide groove 802. The baffle base 801 drives the first wedge block 9 to move. The first wedge block 9 presses the inclined surface of the second wedge block 12, causing the second wedge block 12 to enter the groove 10. The second wedge block 12 no longer obstructs the first wedge block 9, so that the second baffle 8 will not restrict the movement of the aluminum ingot retention box 3. Then, the second spring 805 rebounds, causing the baffle base 801 to return to its original position. Then, the above operation is repeated by several second wedge blocks 12 and first springs 11 in the latter half of the cooling water tank 2, so that the cooling water in the cooling water tank 2 comes into direct contact with the shielded surface of the aluminum ingot multiple times, accelerating the heat transfer speed and achieving a faster final cooling rate.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
