[0028] Example 1:

[0029] like Figs. 1-3 As shown, this utility model provides a casting device, including: a main unit and a receiving assembly 1. The main unit is provided with a forming space, which is suitable for containing molten metal. The main unit is provided with a feeding channel extending in the length direction. One end of the feeding channel is connected to the forming space, and the other end of the feeding channel extends to the end face of the main unit. The main unit is provided with a first fixing part. The receiving assembly 1 is provided with a receiving channel. The top of the receiving assembly 1 is provided with a receiving port connected to the receiving channel. The outer peripheral wall of the receiving assembly 1 is provided with a second fixing part. At least a portion of the receiving assembly 1 is housed in the feeding channel to connect the receiving channel with the feeding channel. The first fixing part and the second fixing part cooperate to fix the receiving assembly 1 to the main unit.

[0030] In some embodiments, the host machine has a forming space inside for containing molten metal. The host machine also has a feeding channel extending along its length. One end of the feeding channel is connected to the forming space, and the other end of the feeding channel extends to the end face of the host machine. The host machine has a first fixing part for fixing the receiving component 1. The receiving component 1 has a receiving channel inside for receiving and transmitting molten metal. The top of the receiving component 1 has a receiving port connected to the receiving channel for introducing molten metal. The outer peripheral wall of the receiving component 1 has a second fixing part for cooperating with the first fixing part of the host machine to fix the receiving component 1 on the host machine.

[0031] At least a portion of the receiving component 1 is housed within the feeding channel of the main unit, thereby connecting the receiving channel with the feeding channel. At this point, the receiving component 1 is initially fixed to the main unit. Subsequently, the first fixing part and the second fixing part cooperate to further fix the receiving component 1 to the main unit.

[0032] Understandably, a portion of the receiving assembly 1 is inserted into the feed channel of the main unit, ensuring that the receiving channel and the feed channel are connected to form a continuous channel. This allows the molten metal to flow from the receiving port through the receiving channel into the feed channel and finally reach the forming space. The connection between the receiving channel and the feed channel ensures the smooth flow of the molten metal, reducing flow resistance and the risk of leakage. Furthermore, the above-mentioned method can initially fix the receiving assembly 1 to the main unit. The cooperation between the first fixing part and the second fixing part ensures that the receiving assembly 1 is firmly fixed to the main unit, preventing loosening or falling off under high temperature and high pressure environments. Moreover, the tight cooperation between the first fixing part and the second fixing part can form a good seal between the receiving assembly 1 and the main unit, preventing leakage of the molten metal during the transmission process.

[0033] According to the casting device of this utility model, the receiving component 1 can be quickly installed into the feeding channel of the main unit through a simple insertion action, and then fixed by the cooperation of the first fixing part and the second fixing part, which simplifies the installation steps of the receiving component 1. Similarly, during disassembly, it is only necessary to release the cooperation of the first fixing part and the second fixing part to remove the receiving component 1 from the feeding channel, which facilitates the maintenance and replacement of the receiving component 1. Of course, the tight cooperation of the first fixing part and the second fixing part ensures a good seal between the receiving component 1 and the main unit, reduces the risk of molten metal leakage, and improves the safety and reliability of the casting process. Moreover, through the cooperation of the first fixing part and the second fixing part, the receiving component 1 can remain stable under high temperature and high pressure environments, and will not loosen or fall off, ensuring the smooth progress of the casting process. At the same time, the receiving component 1's housing and fixing design is intuitive and clear, and operators can easily understand and perform the installation and disassembly steps, reducing the possibility of operational errors.

[0034] Example 2:

[0035] Based on Embodiment 1, the receiving assembly 1 includes a receiving pipe 10 and a connecting pipe 20. The connecting pipe 20 is disposed at one end of the receiving pipe 10 and is adapted to be housed in the feeding channel. The receiving pipe 10 and the connecting pipe 20 together define the receiving channel. In the direction from the receiving pipe 10 to the main unit, the outer diameter of the connecting pipe 20 gradually decreases, and the outer diameter of the receiving pipe 10 is larger than the inner diameter of the feeding channel.

[0036] Understandably, the gradually decreasing outer diameter of the connecting pipe 20 allows it to be smoothly inserted into the feed channel of the main unit, ensuring easy entry and providing sufficient contact area for enhanced sealing. The gradually decreasing outer diameter also ensures a tight contact between the connecting pipe 20 and the inner wall of the feed channel, reducing the risk of molten metal leakage. Furthermore, the outer diameter of the receiving pipe 10 is larger than the inner diameter of the feed channel (the outer diameter of one end of the connecting pipe 20 is smaller than the inner diameter of the feed channel, while the outer diameter of the other end is the same as the outer diameter of the receiving pipe 10). This ensures that the connecting pipe 20 does not enter the feed channel during installation, but rather a portion remains outside, allowing the outer wall of the connecting pipe 20 to contact the inner wall of the feed channel, thus creating a seal. Additionally, the feed pipe is located outwards from the feed channel, facilitating fixation via the fixing part and ensuring sufficient support points for the receiving assembly 1 after installation, thereby improving the connection stability between the receiving assembly 1 and the main unit.

[0037] As a result, the outer diameter of the connecting pipe 20 gradually decreases, allowing the receiving assembly 1 to be easily inserted into the feeding channel, reducing resistance during installation and improving installation efficiency. In other words, the gradually decreasing outer diameter design of the connecting pipe 20 helps the receiving assembly 1 to be quickly positioned during insertion, ensuring accurate alignment between the receiving assembly 1 and the feeding channel.

[0038] Moreover, the outer wall of the connector 20 is in close contact with the inner wall of the feed channel to form a good sealing effect, reducing the risk of leakage of molten metal during the transmission process. The gradually decreasing outer diameter of the connector 20 can also compensate for the dimensional changes caused by thermal expansion to a certain extent, ensuring that good sealing performance can still be maintained under high-temperature working conditions.

[0039] Example 3:

[0040] Based on Embodiment 2, this embodiment has a connecting ear 11 on the outer wall of the receiving tube 10. The connecting ear 11 is rotatably provided with a screw 12 extending in the length direction. The screw 12 is constructed as a second fixing part. The main unit is provided with a threaded hole. The screw 12 cooperates with the threaded hole to fix the receiving assembly 1 to the main unit.

[0041] In some embodiments, the receiving assembly 1 can be securely fixed to the main unit by screwing the screw 12 into the threaded hole on the main unit, which is not only simple and reliable, but also easy to install and disassemble.

[0042] A screw 12 is rotatably provided on the connecting ear 11, which means that the screw 12 can rotate during installation, ensuring that the screw 12 can be smoothly screwed into the threaded hole, improving the convenience of installation. Moreover, by tightening the screw 12, a certain preload can be applied between the receiving assembly 1 and the main unit, making the connecting pipe 20 fit more tightly with the inner wall of the feeding channel, enhancing the sealing performance and reducing the risk of molten metal leakage.

[0043] Understandably, the engagement of the screw 12 with the threaded hole allows the receiving assembly 1 to be quickly fixed on the main unit, simplifying the installation steps and improving installation efficiency. Moreover, by loosening the screw 12, the receiving assembly 1 can be easily disassembled, facilitating the maintenance and replacement of the receiving assembly 1.

[0044] Of course, tightening the screw 12 can apply a pre-tightening force between the receiving assembly 1 and the main unit, making the connecting pipe 20 fit more tightly with the inner wall of the feeding channel, enhancing the sealing performance, reducing the risk of leakage of molten metal, and making the connection between the receiving assembly 1 and the main unit more stable, ensuring that the receiving assembly 1 remains stable under high temperature and high pressure environments, and preventing the receiving assembly 1 from loosening or falling off.

[0045] Therefore, the cooperation between the screw 12 and the threaded hole further improves the fixing effect between the receiving assembly 1 and the main unit. This not only simplifies the installation and disassembly process of the receiving assembly 1, but also enhances the sealing performance by applying pre-tightening force, ensuring the stability and reliability of the receiving assembly 1 under high temperature and high pressure environments.

[0046] According to some embodiments of the present invention, there are multiple screws 12, which are spaced apart on the outer peripheral wall of the receiving tube 10, and the main unit is provided with multiple threaded holes corresponding one-to-one with the multiple screws 12.

[0047] In some embodiments, the receiving assembly 1 can be fixed at multiple points by the cooperation of multiple screws 12 and multiple threaded holes, ensuring the stability and reliability of the receiving assembly 1 on the host machine. Moreover, the uniform distribution of multiple screws 12 makes the receiving assembly 1 more uniformly stressed during installation, reducing the risk of local stress concentration and improving the overall stability.

[0048] Of course, multiple screws 12 can apply preload force separately, making the contact between the receiving assembly 1 and the main unit tighter, enhancing the sealing performance, reducing the risk of molten metal leakage, and the design of multiple screws 12 allows the receiving assembly 1 to be quickly fixed on the main unit, simplifying the installation steps and improving installation efficiency. Similarly, by loosening multiple screws 12, the receiving assembly 1 can be easily disassembled, facilitating the maintenance and replacement of the receiving assembly 1.

[0049] Understandably, by setting multiple screws 12 and corresponding threaded holes, this application further improves the fixing effect between the receiving assembly 1 and the host, which not only simplifies the installation and disassembly process, but also enhances the sealing performance through multi-point pre-tightening force.

[0050] Preferably, the receiving pipe 10 is provided with lifting lugs 13 on its two outer side walls in the width direction. The distance between the lifting lugs 13 and the main unit is greater than the distance between the connecting lugs 11 and the main unit. The main unit is rotatably provided with two hooks above the feeding channel. The two hooks are respectively adapted to cooperate with the two lifting lugs 13.

[0051] It is understood that the receiving assembly 1 includes a receiving pipe 10 and a connecting pipe 20. At least a portion of the connecting pipe 20 is housed within the feed channel of the main unit to initially fix the receiving assembly 1. Subsequently, the engagement of multiple screws 12 with multiple threaded holes can further increase the engagement strength between the main unit and the receiving assembly 1, thereby further fixing the receiving assembly 1. At this time, the stress points of the receiving assembly 1 only include the contact area between the outer peripheral wall of the connecting pipe 20 and the inner peripheral wall of the feed channel, and the engagement points of multiple screws 12 with multiple threaded holes. Thus, by engaging the hook with the lifting lug 13, and since the distance between the lifting lug 13 and the main unit is greater than the distance between the connecting lug 11 and the main unit, the end of the receiving assembly 1 away from the main unit can be stressed, that is, multiple points of the receiving assembly 1 in the length direction can be stressed, making the stress on the receiving assembly 1 more uniform, reducing the risk of local stress concentration, avoiding deformation of the receiving assembly 1, and extending the service life of the receiving assembly 1.

[0052] Example 4:

[0053] Based on Embodiment 2, this embodiment includes a receiving channel comprising a first channel, a second channel, and a third channel. The first channel extends in the height direction and its top end is connected to the receiving port. The second channel is constructed as an arc-shaped channel, with one end connected to the bottom end of the first channel. The third channel extends in the length direction, with one end connected to the other end of the second channel and the other end connected to the feeding channel.

[0054] Understandably, the first channel extends in the height direction, receiving molten metal from the receiving port to ensure that the molten metal can smoothly enter the receiving assembly 1. The second channel is an arc-shaped channel, with one end connected to the bottom of the first channel. The arc design can reduce turbulence and pressure loss of the molten metal at the turning point, ensuring a smooth transition of the molten metal. The third channel extends in the length direction, with one end connected to the other end of the second channel and the other end connected to the feeding channel. The design of the third channel ensures that the molten metal can smoothly enter the feeding channel of the main unit from the receiving assembly 1.

[0055] It should be noted that the arc design of the second channel can reduce splashing of molten metal at the turning point, ensuring that the molten metal flows smoothly into the forming space and improving the casting quality.

[0056] It is worth noting that the arc-shaped second channel design reduces turbulence at the bends of the molten metal, ensuring a smooth flow of the molten metal and reducing flow resistance and pressure loss. In other words, the continuous design of the first, second, and third channels ensures smooth transmission of the molten metal from the inlet to the feed channel, improving casting efficiency. Moreover, the smooth flow path reduces the generation of bubbles and inclusions, thus lowering the defect rate of the castings.

[0057] Meanwhile, the arc-shaped second channel design reduces splashing of molten metal at the turning point, ensuring that the molten metal flows smoothly into the molding space and improving casting quality. In other words, the smooth flow path reduces splashing and waste of molten metal, lowering production costs. Of course, the optimized flow path ensures uniform distribution of molten metal when entering the molding space, improving the quality and consistency of the castings.

[0058] According to some embodiments of the present invention, the bottom wall of the arc-shaped channel includes: a first connecting wall 14 and a second connecting wall 15. The top end of the first connecting wall 14 is connected to the inner wall of the first channel, one end of the second connecting wall 15 is connected to the bottom end of the first connecting wall 14, and the other end of the second connecting wall 15 is connected to the inner wall of the third channel; wherein the curvature of the first connecting wall 14 is less than the curvature of the second connecting wall 15.

[0059] In some embodiments, the top end of the first connecting wall 14 is connected to the inner wall of the first channel, ensuring a smooth transition of the molten metal from the first channel to the arc-shaped channel. One end of the second connecting wall 15 is connected to the bottom end of the first connecting wall 14, and the other end of the second connecting wall 15 is connected to the inner wall of the third channel, ensuring a smooth transition of the molten metal from the arc-shaped channel to the third channel.

[0060] It is worth mentioning that the curvature of the first connecting wall 14 is less than that of the second connecting wall 15, which allows the molten metal to flow more smoothly when passing through the arc-shaped channel, reducing the risk of turbulence and splashing.

[0061] The first connecting wall 14 has a smaller curvature, meaning it is closer to a straight line. Since the first connecting wall 14 is connected to the inner wall of the vertical first channel, when the molten metal enters from the receiving port and contacts the first connecting wall 14, the reflection effect of the first connecting wall 14 allows the molten metal to pass through the first connecting wall 14 quickly. Moreover, the splashing direction of the molten metal on the first connecting wall 14 will not be towards the receiving port, preventing the molten metal from splashing out of the receiving port. This ensures the safety of the casting operation while reducing the loss of molten metal.

[0062] The second connecting wall 15 has a large curvature, meaning that the second connecting wall 15 is more curved. The second connecting wall 15 supports the first connecting wall 14 and the inner wall of the third channel. As a result, the second connecting wall 15 can better guide the molten metal, reduce the turbulence of the molten metal at the bend, and ensure the smoothness of the flow, thereby ensuring that the molten metal can smoothly enter the third channel.

[0063] According to some embodiments of the present invention, at least a portion of the projection of the first connecting wall 14 in the height direction is located within the first channel, and the projection of the second connecting wall 15 in the height direction is spaced apart from the first channel.

[0064] Understandably, with the above settings, when the molten metal enters through the receiving port, the molten metal may either fall directly and contact the first connecting wall 14, or it may first contact the inner wall of the first channel and, after being reflected by the inner wall of the first channel, continue to fall and contact the first connecting wall 14. That is, the above settings can ensure that after the molten metal enters the receiving channel, it will definitely contact the first connecting wall 14 first and then the second connecting wall 15. This can prevent the molten metal from splashing out of the receiving port and ensure that the molten metal enters the third channel smoothly and steadily.

[0065] According to some embodiments of the present invention, the coefficient of thermal expansion of the connecting pipe 20 is greater than that of the host machine.

[0066] It is understandable that the coupling pipe 20 has a larger coefficient of thermal expansion, meaning that when the temperature rises, the expansion of the coupling pipe 20 will be greater than that of the host; the host has a lower coefficient of thermal expansion, meaning that when the temperature rises, the expansion of the host is relatively smaller.

[0067] Because the coefficient of thermal expansion of the connecting pipe 20 is greater than that of the main unit, the connecting pipe 20 will expand more than the main unit when the temperature rises. This makes the contact between the connecting pipe 20 and the inner wall of the feed channel tighter, enhancing the sealing performance. The tight contact can effectively reduce the risk of leakage of molten metal during the transmission process, ensuring the safety and reliability of the casting process. Moreover, the expansion of the connecting pipe 20 increases the friction between the connecting pipe 20 and the inner wall of the feed channel, reducing the risk of the connecting pipe 20 loosening or falling off in high-temperature environments and improving the stability of the receiving assembly 1.

[0068] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
