Description

Technical Field

[0001] This utility model relates to the technical field of aluminum rod casting equipment, and more specifically, to an aluminum rod casting device. Background Technology

[0002] Aluminum bars are an important intermediate product in the aluminum processing industry, widely used in construction, transportation, electronics, and aerospace. Continuous casting or semi-continuous casting is a common process for producing aluminum bars. It involves pouring molten aluminum into a crystallizer, forcibly cooling it with cooling water, solidifying it, and then drawing out aluminum bars of a specific length by a traction mechanism. In existing aluminum bar casting equipment, such as the casting equipment for high-strength aluminum alloy long ingots disclosed in CN201940557U, the equipment includes a mold body and a bottom mold. The crystallizing disc is horizontally placed above a lifting platform on a support, the bottom mold is fixed on the lifting platform, and the mold body, fixed to the bottom of the crystallizing disc, is directly above the bottom mold. The above equipment has the following technical problems: the production mold cannot be quickly assembled and disassembled according to actual production needs, and demolding is not quick, resulting in increased costs. Utility Model Content

[0003] Based on this, in order to solve the problem that existing casting equipment cannot quickly disassemble and assemble molds and quickly demold, this utility model provides an aluminum rod casting device, the specific technical solution of which is as follows: An aluminum rod casting apparatus includes a casting mechanism and a demolding mechanism. The casting mechanism includes a casting frame, a centrifugal shell, and a liquid inlet trough slidably mounted on the casting frame. The centrifugal shell is rotatably mounted on the casting frame, and a mold is detachably fixed inside the centrifugal shell. One end of the liquid inlet trough extends into the interior of the mold. The demolding mechanism includes a track base, a movable frame, and a demolding assembly. The movable frame is slidably mounted on the track base. One end of the demolding assembly is rotatably mounted on the movable frame, and the other end of the demolding assembly extends into the interior of the mold. A demolding clamp protrudes from the demolding assembly, and the demolding clamp is provided with multiple support clamps that abut against the inner wall of the mold.

[0004] The aforementioned aluminum rod casting device, by rotating the centrifugal shell on the casting frame and causing the mold to rotate at high speed along with it, utilizes centrifugal force to make the molten aluminum adhere tightly to the inner wall of the mold, greatly improving the density and uniformity of the aluminum rod and effectively eliminating defects such as porosity and inclusions. The demolding clamps and multiple supporting blocks on them can abut against the inner wall of the mold at multiple points, thereby achieving uniform circumferential holding and support of the solidified aluminum rod. When pulling the aluminum rod to demold, it can effectively prevent surface indentations or overall deformation of the aluminum rod caused by excessive local stress, ensuring the dimensional accuracy and geometric shape of the aluminum rod. Furthermore, the design of the mold being detachably fixed inside the centrifugal shell allows for quick replacement when producing aluminum rods of different specifications or when the mold needs maintenance, improving the flexibility and utilization rate of the equipment.

[0008] Furthermore, a first driving component and a second driving component are also installed on the casting frame. The first driving component and the second driving component are respectively disposed on both sides of the casting frame. A first rotating shaft is sleeved on the output end of the first driving component, and a second rotating shaft is sleeved on the output end of the second driving component. Multiple rollers are sleeved on both the first rotating shaft and the second rotating shaft.

[0009] Furthermore, the centrifuge shell includes a shell, an inner core, and a mold that is detachably snapped into the inner core. The inner core is fixed inside the shell, and a locking structure is provided on the inner core. A locking block for snapping and fixing the mold is rotatably provided on the locking structure.

[0010] Furthermore, the track seat is provided with a second transverse guide rail, the movable frame is slidably assembled on the second transverse guide rail, and a plurality of support frames are provided between the movable frame and the centrifuge shell, with the plurality of support frames slidably assembled on the second transverse guide rail at intervals.

[0011] Furthermore, the demolding assembly includes an extension cylinder, a connecting seat, and a demolding clamp inserted on the connecting seat. One end of the extension cylinder is rotatably mounted on the movable frame, and the other end of the extension cylinder is fitted with the connecting seat. The outer circumference of the demolding clamp is provided with a plurality of support clamps that rotate upward.

[0012] Furthermore, auxiliary components are symmetrically arranged on both sides of the support frame. Each auxiliary component includes a swing platform, a third drive member, an auxiliary wheel, and a fourth drive member. The swing platform is rotatably mounted on the top of the support frame.

[0020] like Figures 1-3 As shown, an aluminum rod casting device according to one embodiment of the present invention includes a casting mechanism and a demolding mechanism. The casting mechanism includes a casting frame 1, a centrifugal shell 2, and a liquid inlet trough 3 slidably mounted on the casting frame 1. The centrifugal shell 2 is rotatably mounted on the casting frame 1, and a mold 23 is detachably fixed inside the centrifugal shell 2. One end of the liquid inlet trough 3 extends into the interior of the mold 23. The demolding mechanism includes a track seat 4, a movable frame 5, and a demolding component 6. The movable frame 5 is slidably mounted on the track seat 4. One end of the demolding component 6 is rotatably mounted on the movable frame 5, and the other end of the demolding component 6 extends into the interior of the mold 23. A demolding clamp 61 is protruding on the demolding component 6, and a plurality of support clamps 62 abutting against the inner wall of the mold 23 are provided on the demolding clamp 61.

[0021] The aforementioned aluminum rod casting device, by rotating the centrifugal shell 2 onto the casting frame 1, causes the mold 23 to rotate at high speed along with it. Centrifugal force is used to tightly adhere the molten aluminum to the inner wall of the mold 23, greatly improving the density and uniformity of the aluminum rod and effectively eliminating defects such as porosity and inclusions. The demolding clamp 61 and its multiple supporting clamps 62 can abut against the inner wall of the mold 23 from multiple points, achieving uniform circumferential holding and support of the solidified aluminum rod. When the aluminum rod is demolded, it effectively prevents surface indentations or overall deformation caused by excessive local stress, ensuring the dimensional accuracy and geometric shape of the aluminum rod. Furthermore, the design of the mold 23 being detachably fixed inside the centrifugal shell 2 allows for quick replacement when producing aluminum rods of different specifications or when the mold 23 needs maintenance, improving the flexibility and utilization rate of the equipment.

[0022] like Figure 1As shown, in one embodiment, the casting frame 1 is covered with a protective cover 7, and a liquid inlet pipe 71 is installed on the top of the protective cover 7. The protective cover 7 can effectively prevent dangers that may occur during the casting process due to loosening of the mold 23, splashing of aluminum liquid, or accidental breakage of parts, and greatly protect the personal safety of the operators.

[0023] In one embodiment, the top of the liquid inlet pipe 71 is provided with a liquid inlet funnel, and the bottom of the liquid inlet pipe 71 is connected to an outlet channel located above the liquid inlet tank 3.

[0024] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of rollers 11 located on both sides of the centrifuge shell 2 are rotatably arranged on one end of the casting frame 1, and a first transverse guide rail is provided on the other end of the casting frame 1. The centrifuge shell 2 is mounted on the rollers 11, and a liquid inlet cart is slidably mounted on the first transverse guide rail. The liquid inlet tank 3 is fixed on the liquid inlet cart.

[0025] Specifically, the first transverse guide rail is set in a horizontal direction.

[0026] In one embodiment, a first driving component and a second driving component are also installed on the casting frame 1. The first driving component and the second driving component are respectively disposed on both sides of the casting frame 1. A first rotating shaft is sleeved on the output end of the first driving component, and a second rotating shaft is sleeved on the output end of the second driving component. Multiple rollers 11 are sleeved on both the first rotating shaft and the second rotating shaft. The rollers 11 greatly reduce the rotational resistance, making it easier for the centrifugal shell 2 to reach and maintain the high rotational speed required for casting, thereby ensuring the process effect of centrifugal casting and reducing drive energy consumption.

[0027] like Figure 1 and Figure 2 As shown, in one embodiment, the centrifuge shell 2 includes a shell 21, an inner core 22, and a mold 23 detachably snapped into the inner core 22. The inner core 22 is fixed inside the shell 21 and has a locking structure. A locking block 24 for snapping and fixing the mold 23 is rotatably mounted on the locking structure. When different specifications of aluminum rods need to be produced or the mold 23 needs maintenance, the operator does not need to disassemble the entire centrifuge shell 2 assembly; they only need to unlock it to remove the mold 23 separately from the inner core 22. This greatly simplifies the operation process, shortens equipment downtime, and improves production flexibility.

[0028] like Figure 1 and Figure 2As shown, in one embodiment, the track base 4 is provided with a second transverse guide rail, and the moving frame 5 is slidably mounted on the second transverse guide rail. A plurality of support frames 8 are provided between the moving frame 5 and the centrifugal shell 2, and these support frames 8 are slidably mounted on the second transverse guide rail at intervals. During the demolding process, as the aluminum rod is gradually pulled out of the mold 23, these support frames 8 can move synchronously with the moving frame 5, always providing spaced and uniform bottom support for the aluminum rod that has been demolded.

[0029] Specifically, the second transverse guide rail is set in a horizontal direction.

[0030] like Figure 2 As shown, in one embodiment, the demolding assembly 6 includes an extension cylinder 63, a connecting seat 64, and a demolding clamp 61 inserted into the connecting seat 64. One end of the extension cylinder 63 is rotatably mounted on the movable frame 5, and the other end of the extension cylinder 63 is fitted with the connecting seat 64. Multiple support clamping blocks 62 are rotatably mounted on the outer periphery of the demolding clamp 61. The support clamping blocks 62 can rotate individually to contact the inner wall or end face of the aluminum rod at an optimal angle, ensuring a uniform distribution of clamping force and avoiding scratches or localized crushing of the aluminum rod's inner wall that might be caused by traditional rigid clamps, thus perfectly protecting the surface quality of the aluminum rod.

[0031] like Figure 1 As shown, in one embodiment, auxiliary components are symmetrically arranged on both sides of the support frame 8. Each auxiliary component includes a swing platform, a third drive member, auxiliary wheels 81, and a fourth drive member. The swing platform is rotatably mounted on top of the support frame 8. The third drive member is mounted on the support frame 8 and controls the swing state of the swing platform. The auxiliary wheels 81 are rotatably mounted on the swing platform. The fourth drive member is mounted on the swing platform and controls the rotation state of the auxiliary wheels 81. An auxiliary gap for supporting the aluminum rod is formed between the two auxiliary wheels 81 on both sides. The symmetrically arranged auxiliary wheels 81 are in line contact with the outer circumference of the aluminum rod, resulting in a uniform distribution of supporting force. Operators can slightly adjust the gripping tightness of the aluminum rod by controlling the swing of the swing platform as needed. This provides sufficient support to prevent sagging while avoiding damage to the aluminum rod surface due to excessive rigid clamping force, perfectly protecting the product's appearance quality.

[0032] like Figure 3 As shown, in one embodiment, the support clamp 62 has a plurality of heat dissipation holes 621 evenly distributed on it. Both ends of the support clamp 62 are provided with strip-shaped anti-slip textures 622, and the anti-slip textures 622 at both ends are perpendicular to each other. The heat dissipation holes 621 are provided with protrusions 623 along the axial direction of the heat dissipation holes 621. This makes the support clamp 62 have good heat dissipation effect under high temperature and high pressure conditions, high structural strength, and is not easily deformed.

[0033] Specifically, the protruding rib 623 is elongated. The protruding rib 623 can increase the area of ​​the heat dissipation hole 621 and accelerate heat dissipation. At the same time, the protruding rib 623 can also act as a reinforcing rib to increase the strength of the support clamp 62 and make the support clamp 62 less prone to deformation.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
