Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy melting and casting, in particular to a crystallizer for aluminum alloy melting and casting. Background Art

[0002] The semi-continuous casting process is a common production method for aluminum alloy ingots. The method of semi-continuous casting of aluminum alloy is as follows: within a certain period of time, the molten metal is continuously poured into the crystallizer at a certain pouring speed, and the ingot is continuously pulled out at a certain speed to form an aluminum alloy ingot. The crystallizer is an important equipment for semi-continuous casting.

[0003] However, the existing crystallizer structures are often fixedly connected and cannot be disassembled. As a result, when a certain structure of the crystallizer fails, it is impossible to replace the damaged structure, and only the whole crystallizer can be replaced, which increases the production cost. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a crystallizer for aluminum alloy melting and casting.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A crystallizer for aluminum alloy melting and casting includes a base, a sleeve and a base. The base is arranged between the sleeve and the base. One side of the sleeve is provided with a cylinder penetrating the bottom of the sleeve. The output end of the cylinder is provided with a telescopic rod perpendicular to the cylinder. The end of the telescopic rod is fixed with a clamping block, and a return spring wound around the telescopic cylinder of the telescopic rod is arranged between the telescopic rod fixing cylinder and the clamping block. A limiting hole is opened at the bottom of the other side of the sleeve. An opening for inserting the cylinder is opened on one side of the base, and a limiting rod adapted to the limiting hole is fixed at the top of the other side of the base. A slot for inserting the telescopic rod is opened on the side of the base, and a slot adapted to the clamping block is communicated with the side of the slot, and the slot and the outside of the slot are opened.

[0007] Preferably, an inner cylinder is arranged on the top of the base, and a connecting cylinder is arranged on the top of the base. When the top surface of the base is attached to the bottom surface of the base, the top surface of the connecting cylinder is attached to the bottom surface of the inner cylinder.

[0008] Preferably, the inner cylinder is arranged on the top of the base through a fixing rod.

[0009] Preferably, the outer diameter of the connecting cylinder is smaller than the outer diameter of the inner cylinder, and the inner diameter of the connecting cylinder is the same as the inner diameter of the inner cylinder.

[0010] Preferably, when the top surface of the base is attached to the bottom surface of the base, the horizontal height of the inner top surface of the connecting cylinder is equal to the horizontal height of the top surface of the base.

[0011] Preferably, a limiting groove is formed in the cylinder, a limiting block is inserted into the limiting groove, and the distance between the top surface of the limiting block and the bottom surface of the sleeve is equal to the thickness of the base.

[0012] Preferably, the output end of the cylinder penetrates through the telescopic rod, and a groove for inserting the output end of the cylinder is communicated with the bottom of the slot.

[0013] Preferably, there is a distance between the circle formed by the inner diameter of the sleeve and the slot.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, due to the cooperation relationship between the limiting rod and the limiting hole, when the sleeve is located on the top of the base, it cannot move forward, backward, left, right, or upward. At the same time, due to the cooperation relationship between the limiting groove and the limiting block, the sleeve cannot move upward, thus realizing the stable connection between the sleeve and the base. The disassembly can be completed by removing the limiting block. After the telescopic rod is inserted into the slot, the elastic force of the return spring makes the clamping block insert into the clamping groove, thereby realizing the stable connection between the sleeve and the base. Pressing the clamping block to separate the telescopic rod from the slot can complete the disassembly. While the various structures are stably connected, the disassembly work is also very convenient, which is beneficial to the later maintenance and replacement.

[0016] 2. In the present utility model, the cooling water is added through the gap between the sleeve and the inner cylinder. The space is small, which is beneficial to quickly adding the cooling water to the specified height and then carrying out the cooling work, and can improve the work efficiency to a certain extent.

[0027] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation methods. Therefore, the following detailed implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0028] As Figure 1 shown, as a crystallizer for aluminum alloy melting and casting of the present invention, it includes a base 1, a sleeve 2 and a base 3. As Figure 5 shown, an opening 17 is provided on one side of the base 1, and a limit rod 16 is fixed at the top of the other side of the base 1. An inner cylinder 15 is provided on the top of the base 1 through a fixed rod 14. As Figure 3 shown, a cylinder 5 penetrating the bottom of the sleeve 2 is provided on one side of the sleeve 2, a limit hole 4 is opened at the bottom of the other side of the sleeve 2, and a limit groove 18 is opened on the cylinder 5. As Figure 2 shown, a limit block 11 is inserted into the limit groove 18, and the distance between the top surface of the limit block 11 and the bottom surface of the sleeve 2 is equal to the thickness of the base 1. When the cylinder 5 is inserted into the opening 17, the sleeve 2 is lowered from above the inner cylinder 15 until the limit rod 16 at the top of the base 1 is inserted into the limit hole 4 at the bottom of the sleeve 2, so as to limit the sleeve 2 in the front, back, left, right and downward directions. By inserting the limit block 11 into the limit groove 18, the sleeve 2 is limited in the upward direction, so as to realize the stable connection between the sleeve 2 and the base 1. At the same time, removing the limit block 11 can complete the disassembly. Cooling water is added through the gap between the sleeve 2 and the inner cylinder 15. The space is small, which is conducive to quickly adding the cooling water to the specified height and then carrying out the cooling work, and can improve the work efficiency to a certain extent.

[0029] As Figure 3As shown, the output end of the cylinder 5 is provided with a telescopic rod 6 perpendicular to the cylinder 5, a clamping block 8 is fixed at the end of the telescopic rod 6, and a return spring 7 wound on the telescopic cylinder of the telescopic rod 6 is provided between the fixing tube of the telescopic rod 6 and the clamping block 8. A slot 9 for inserting the telescopic rod 6 is provided on the side of the base 3. There is a gap between the circle formed by the inner diameter of the sleeve 2 and the slot 9 to ensure that the cooling water does not flow out through the slot 9. The output end of the cylinder 5 passes through the telescopic rod 6, and the bottom of the slot 9 is connected to a groove 12 for inserting the output end of the cylinder 5. The output end of the cylinder 5 is inserted into the groove 12. The cylinder 5 cannot move forward, backward, left, right, and downward, thereby ensuring the stability of the relative position between the cylinder 5 and the slot 9. The side of the slot 9 is connected to a slot 10 that is compatible with the block 8, and the slot 10 is connected to the outside of the slot 9. After the telescopic rod 6 is inserted into the slot 9, the block 8 is inserted into the slot 10 through the rebound force of the reset spring 7, thereby realizing a stable connection between the sleeve 2 and the base 3, so that the sleeve 2 and the base 3 are stably arranged on the upper and lower sides of the base 1 respectively. At the same time, the block 8 is pressed to disengage the telescopic rod 6 from the slot 9 to complete the disassembly.

[0030] like Figure 4 As shown, a connecting tube 13 is provided on the top of the base 3. When the top surface of the base 3 is in contact with the bottom surface of the base 1, the top surface of the connecting tube 13 is in contact with the bottom surface of the inner tube 15. The metal liquid is formed by the connecting tube 13 and the inner tube 15 through the contact between the connecting tube 13 and the inner tube 15. The outer diameter of the connecting tube 13 is smaller than the outer diameter of the inner tube 15, and the inner diameter of the connecting tube 13 is the same as the inner diameter of the inner tube 15, which means that the wall thickness of the connecting tube 13 is smaller than the wall thickness of the inner tube 15, which is beneficial to the cooling of the metal liquid in the connecting tube 13. When the top surface of the base 3 is in contact with the bottom surface of the base 1, the horizontal height of the top surface of the connecting tube 13 is equal to the horizontal height of the top surface of the base 1, ensuring that the end of the metal liquid can be cooled and thus ensuring the comprehensiveness of the cooling work.

[0031] When in use, cooling water is added between the sleeve 2 and the inner cylinder 15, and the molten metal is poured into the inner cylinder 15 from above the inner cylinder 15. The molten metal flows into the connecting cylinder 13 and is blocked and accumulated to form. The cooling water cools the molten metal in the inner cylinder 15 through the inner cylinder 15 and the side wall of the connecting cylinder 13. The cylinder 5 works to push the sleeve 2 away from the base 1 to pull the ingot out. At the same time, the cooling water directly cools the ingot through the gap between the inner cylinder 15 and the base 1, thereby improving the cooling efficiency.

[0032] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
