Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a multi-channel hot-top aluminum alloy round casting mold. Background Technology

[0002] Multi-channel hot-top aluminum alloy round casting mold is a type of mold used for casting aluminum alloy round casting rods. It has multiple runners and a hot-top structure, which can improve casting efficiency and product quality. In the production of multi-channel hot-top aluminum alloy round casting rods, the performance of the casting mold is directly related to product quality and production efficiency. As a key component of the casting mold, the cooling system plays a crucial role in the solidification process and final performance of the casting.

[0003] In actual operation, the cooling water for multi-channel hot-top aluminum alloy round casting molds is usually taken from ordinary water sources, which inevitably contain a large number of impurities, such as sand particles, rust fragments, dirt formed by microbial growth, and various scale deposits. Once these impurities enter the cooling channels of the mold with the cooling water flow, they gradually accumulate in the cooling channels, resulting in a smaller channel diameter and a smaller water flow cross-sectional area. This reduces the cooling water flow rate and significantly decreases the heat exchange efficiency, making it impossible to remove the heat generated during the solidification process of the casting in time. Utility Model Content

This invention can solve the problem that cooling water is usually taken from ordinary water sources, which inevitably contain a large number of impurities, such as sand particles, rust fragments, dirt formed by microbial growth, and various scale deposits. Once these impurities enter the cooling channel of the mold with the cooling water flow, they gradually accumulate in the cooling channel, resulting in a smaller channel inner diameter and a smaller water flow cross-sectional area. This reduces the cooling water flow rate, significantly decreases the heat exchange efficiency, and fails to remove the heat generated during the solidification process of the casting in a timely manner.

The outer walls of the four fixed blocks are threaded with fixing bolts. The outer walls of the four T-shaped blocks are provided with fixing bolt grooves. The two filter devices are connected to the flanges at both ends of the cooling pipe.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a multi-channel hot-top aluminum alloy round casting mold, including a support base 1, a cooling pipe 7 and a mounting base 4;

[0031] Both ends of the cooling pipe 7 are equipped with filter devices;

[0032] The filtration device includes a filter tank 3, a support frame 18, and two sliding blocks 9. A cooling pipe 7 is installed and fixed inside the support base 1. Two sliding block grooves 10 are formed on the upper surface of the filter tank 3; both grooves are arc-shaped. The support frame 18 is fixedly connected to the lower outer wall of one side of the support base 1. The outer wall of the filter tank 3 is fixedly connected to the outer wall of the support frame 18 at the end furthest from the support base 1. The outer walls of the two sliding blocks 9 are slidably connected to the interior of their respective sliding block grooves 10. Both ends of the cooling pipe 7 extend fixedly to the outside of the support base 1 and are equipped with flanges. One end of the filter tank 3 is connected to one end of the cooling pipe 7 via a flange. A coarse filter screen 15 is fixedly connected to the inner wall of the front sliding block 9. Four fixing blocks 12 are fixedly connected to the outer wall. The upper surface of each of the four fixing blocks 12 is provided with a T-shaped block groove 8. Two T-shaped blocks 14 are fixedly connected to the outer wall of each of the two sliding blocks 9. The outer walls of the four T-shaped blocks 14 are slidably connected to the interior of the corresponding T-shaped block groove 8. A fine filter screen 16 is fixedly connected to the inner wall of the rear sliding block 9. Fixing bolts 11 are threadedly connected to the outer walls of the four fixing blocks 12. Fixing bolt grooves 17 are provided on the outer walls of the four T-shaped blocks 14. The ends of the four fixing bolts 11 near the fixing bolt grooves 17 are threaded into the interior of the T-shaped block grooves 8 and are threadedly connected to the interior of the corresponding fixing bolt grooves 17. The two filter devices are connected to the flanges at both ends of the cooling pipe 7.

[0033] The support base 1 has four support columns at the top end that are away from the support base 1 and are fixedly connected to a top plate 6. A cylinder 5 is installed on the upper surface of the top plate 6. The output end of the cylinder 5 slides to the outside of the top plate 6 and is fixedly connected to the upper surface of the mounting base 4. A moving mold 13 is installed on the lower surface of the mounting base 4. A fixed mold 2 is installed inside the groove at the top end of the support base 1. A semi-circular flow channel is opened inside the fixed mold 2. The lower surface of the moving mold 13 has multiple semi-circular flow channels. The semi-circular flow channels on the fixed mold 2 and the moving mold 13 cooperate to form parallel flow channels. The two sliding rods on the top plate 6 are slidably connected at the end near the mounting base 4 and both slide to the outside of the top plate 6 and are fixedly connected to the upper surface of the mounting base 4. The mounting base 4 is slidably connected to the outer wall of the four support columns on the support base 1.

[0034] Furthermore, when using this device, it is started by connecting to an external power source. When casting is required, the output end of cylinder 5 extends, pushing the mounting base 4 and the moving mold 13 downwards. Under the guidance of the slide rod, the moving mold 13 smoothly closes with the fixed mold 2. The semi-circular flow channels on the fixed mold 2 and the moving mold 13 combine to form a complete parallel flow channel. Then, the external equipment injects molten aluminum alloy into the parallel flow channel formed by the fixed mold 2 and the moving mold 13 through a specific gate. Under the action of gravity or other external forces, the aluminum alloy flows along the parallel flow channel and fills the entire flow channel space. During the cooling and solidification process of the aluminum alloy, it is then connected to the external equipment flange through one end of two filter tanks 3. Then, before entering the cooling pipe 7, the cooling medium first flows into... The cooling medium, after being initially filtered by the coarse filter 15, continues to flow through the filter tank 3 of the filtration device. It then passes through the fine filter 16, which further filters out tiny particles of impurities, such as rust and fine suspended matter, ensuring that the cooling medium entering the cooling pipe 7 has a high purity. This prevents impurities from clogging or wearing the cooling pipe 7, ensuring the normal operation of the cooling system and thus guaranteeing the forming quality and internal structure properties of the aluminum alloy round casting rod. When it is necessary to disassemble the filter, loosen the fixing bolt 11 so that it exits from the fixing bolt slot 17 of the T-block 14. Then slide the T-block 14 along the T-block slot 8 and remove the sliding block 9 from the filter tank 3. This allows for the cleaning or replacement of the coarse filter 15 and the fine filter 16.

[0035] Before entering the cooling pipe 7, the cooling medium in the filtration device first flows into the filter tank 3 of the filtration device. After being initially filtered by the coarse filter screen 15, the cooling medium continues to flow and then passes through the fine filter screen 16. The fine filter screen 16 further filters out small particles of impurities, ensuring that the cooling medium entering the cooling pipe 7 has a high purity. This avoids impurities from clogging or wearing the cooling pipe 7, ensuring the normal operation of the cooling system and thus guaranteeing the forming quality and internal structure properties of the aluminum alloy round casting rod, thereby improving the practicality and service life of the equipment.
