[0002] The existing casting mechanism for adjustable paddle has an included angle between the original pitch angle of the adjustable paddle and the horizontal plane ranging from 35 to 55 degrees, which has the following problems.
[0003] On the one hand, such high inclination is not conducive to the installation of the paddle mold. Due to the large angle, the mold may not be tightly connected with the production equipment, resulting in difficult installation and unstable fixation, which not only increases the workload in the installation process, but also may have a negative impact on the precision and stability of the mold.
[0004] On the other hand, high inclination also has higher requirements for the feeding neck. The feeding neck is an important part in the casting process for supplementing metal liquid to eliminate shrinkage holes and shrinkage. If the feeding neck is not properly designed or cannot meet the requirements under high inclination, the process yield will be greatly reduced. Specifically, high inclination may cause vortex or turbulence in the flowing process of the pouring liquid, thereby affecting the feeding effect and increasing the risk of defects in the casting.
[0005] In addition, high inclination also increases the difficulty of pouring. Due to high inclination, the pouring liquid may encounter greater resistance in the flowing process, resulting in poor flow or splashing, which not only affects the accuracy and uniformity of pouring, but also threatens the safety of the operator.

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0024] The following is in conjunction with the appendix Figures 1-2 The present invention will be described in further detail below.
[0025] This utility model discloses a casting mechanism for adjustable slurry.
[0026] Reference Figure 1 , Figure 2 A casting mechanism for adjustable slurry includes a casting device, a paddle mold 1, a casting platform 2, a first riser 3, and a second riser 4. The paddle mold 1 has a third riser 5 that flows through its interior. The second riser 4 is located on the casting platform 2 and has two discharge ports. The first riser 3 is positioned above the second riser 4 and flows through the first discharge port. The paddle mold 1 is located on one side of the second riser 4 and flows through the second discharge port. The casting platform 2 has a slag collection basin 8 that flows through the second riser 4. The casting device is used to inject the casting liquid into the second riser 4 and fill the paddle mold 1. This design eliminates the need for necking, chills, and quench sand, reduces the riser size, makes the molding process easier for workers, improves quality, reduces post-processing steps, lowers labor costs, and significantly increases the yield.
[0027] In this embodiment, the casting platform 2 serves as the foundation for supporting the blade mold 1, riser 1 3, riser 2 4, and riser 3 5. Riser 2 4 is installed on the casting platform 2, and a slag collection pit 8 is formed in the center of the casting platform 2. The residues remaining in riser 1 3, riser 2 4, blade mold 1, and riser 3 5 flow into and settle in the slag collection pit 8 under the action of gravity, resulting in high purity and improved quality of the blade mold 1. This reduces post-processing steps, lowers labor costs, and greatly improves the process yield.
[0028] A slag collection pit 8 is installed in the casting device to collect and settle slag, thereby improving the quality of castings, reducing defects and scrap rates, and lowering production costs.
[0029] In this embodiment, the side wall of riser 2 4 is provided with a blade mold 1. The blade mold 1 is used to cast adjustable slurry. When the inside of the blade mold 1 is filled with casting liquid and completely cooled, the adjustable slurry is formed.
[0030] In the embodiment, the paddle mold 1 can be provided in multiple along the circumference of the riser two 4, improving the casting efficiency of the paddle mold 1, and multiple adjustable paddles can be cast at one time, greatly improving the work efficiency. Specifically, the paddle mold 1 is provided on both sides of the riser two 4.
[0031] In the embodiment, the riser three 5 has an exhaust port, and the exhaust port is provided with an exhaust pipe 6. The casting liquid enters the paddle mold 1 through the riser two 4, and then the excess casting liquid in the paddle mold 1 enters the riser three 5. The exhaust pipe 6 is used to exhaust the excess air during the entire casting process through the exhaust pipe 6. By discharging the gas in time through the exhaust pipe 6, the gas holes, slag inclusions and other defects in the casting can be effectively reduced, and the qualified rate and overall quality of the casting can be improved. The exhaust pipe 6 can also help control the solidification process of the casting, reduce shrinkage holes, shrinkage and other problems caused by gas retention, and make the casting liquid fill the mold cavity more smoothly, thereby improving the casting efficiency. At the same time, the exhaust pipe 6 can also help to adjust the pressure distribution in the paddle mold 1, so that the casting is subjected to more uniform pressure during solidification, thereby obtaining better microstructure and mechanical properties.
[0032] The pouring table 2 is provided with a pouring pipe 7, and the pouring device is injected into the riser two 4 through the pouring pipe 7. Specifically, the pouring pipe 7 is provided in multiple along the circumference of the riser two 4, and the pouring table 2 is provided with a pouring ring. The pouring ring is provided with multiple pouring pipes 7, and the pouring ring has an inlet which is in communication with the pouring device. Since the casting liquid is poured from bottom to top through the pouring pipe 7, pouring from bottom to top helps to push the air and gas in the mold cavity to move upwards and be discharged through the exhaust pipe 6 arranged at the top of the mold. This pouring method helps to reduce the retention of gas in the casting, thereby reducing the risk of defects such as gas holes, slag inclusions and the like. Pouring from bottom to top makes the casting liquid fill the mold cavity more smoothly, especially in complex-shaped molds. This flow pattern helps to reduce the vortex and turbulence of the casting liquid, thereby reducing the possibility of defects such as shrinkage holes, shrinkage and the like in the casting.
[0033] Multiple pouring pipes 7 are distributed along the circumference to form multi-point pouring, which can ensure that the casting liquid fills the mold cavity more uniformly. This uniform filling helps to reduce defects caused by uneven flow of the casting liquid, such as vortex, turbulence and cold shut. Multi-point pouring helps to push the air and gas in the mold cavity to move to the top and edge of the mold and be discharged through the exhaust pipe 6 arranged at the appropriate position, which helps to reduce the retention of gas in the casting, thereby reducing the risk of defects such as gas holes, slag inclusions and the like.
[0034] The pouring device includes a cross runway 9 and a sprue 10, and the sprue 10 is used to flow the casting liquid into the cross runway 9, and the cross runway 9 is in communication with the pouring ring.
[0035] The sprue 10, as the starting section in the casting device, its main responsibility is to guide the casting liquid (such as copper liquid) from the external source and flow into the runner 9, so that the liquid can be quickly and smoothly transmitted during the casting process, facilitating the inflow of the liquid. The runner 9 is a key channel in the casting device, which is responsible for further guiding the casting liquid flowing in the sprue 10 to the casting ring. The runner 9 plays an important connecting role between the sprue 10 and the mold cavity, and they work together to ensure that the casting liquid can fill the mold cavity smoothly and uniformly, thereby producing high-quality castings.
[0036] A filter device 11 is provided between the runner 9 and the sprue 10. The main function of the filter device 11 is to capture and remove impurities in the casting liquid, such as metal oxides, non-metallic inclusions, bubbles, etc. Avoiding impurities entering the mold cavity may cause defects in the castings, such as porosity, slag inclusion, cracks, etc. By filtering out impurities, the filter device 11 can improve the flowability of the casting liquid, making it more smoothly fill the mold cavity, which helps to reduce casting defects caused by poor flow. The use of the filter device 11 can significantly improve the quality of the castings, reduce defects caused by impurities, and improve the mechanical properties and appearance quality of the castings. In this embodiment, the filter device 11 includes a filter screen, and the filter device 11 uses a filter element of the prior art.
[0037] The angle range of the paddle mold pitch is 15°-35°. In the adjustable paddle original pitch state, the angle between the adjustable paddle original pitch and the horizontal plane is in the range of 35-70°. Due to the high inclination, on the one hand, it is not conducive to the installation of the paddle mold 1, and the installation and fixation requirements are high, and secondly, the feeding neck requirement is high, otherwise the process yield will be greatly discounted. On the other hand, it is difficult to cast, because of the high inclination, high inclination may cause vortex or turbulent flow of the metal liquid during the flow process, thereby affecting the feeding effect and increasing the risk of casting defects. Due to the high inclination, the casting liquid may encounter greater resistance during the flow process, resulting in poor flow or splashing. This not only affects the accuracy and uniformity of the casting, but also may pose a threat to the safety of the operator.
[0038] In this embodiment, the pitch of the traditional paddle mold 1 is rotated 15°-35° towards the direction close to the horizontal plane, so that the angle range of the pitch angle of the installed paddle mold is 15°-35°. By using the above angle range, it is beneficial to the installation and fixation of the paddle mold 1, and the paddle mold 1 can be more easily connected with the production equipment, thereby reducing the feeding neck, and the fixation is also more stable, ensuring that the mold remains stable during the casting process, facilitating the installation and fixation of the paddle mold 1, and ensuring the stability of the casting process.
[0039] In the embodiment, the leading edge refers to the front edge of the blade, i.e. the part of the blade that first contacts the fluid when rotating. The trailing edge is the rear edge of the blade, i.e. the part of the blade where the fluid leaves. The leading edge of the blade mold 1 is slightly higher than the trailing edge of the blade mold 1, which can improve the propulsion performance and the casting quality, facilitate the subsequent manual removal of the blade mold 1, reduce the post-processing procedures, reduce the labor cost, and greatly improve the process yield.
[0040] A feeding channel 12 is arranged between the riser two 4 and the riser three 5. The feeding channel 12 is used to connect the riser and the part of the casting that needs feeding, ensure that the casting liquid can effectively feed, avoid shrinkage holes and shrinkage, help to ensure that the casting organization is dense, no shrinkage holes and porosity, and improve the casting quality. In the embodiment, the feeding channel 12 is arranged above the riser two 4 and at the connection of the riser three 5, which is near the last solidification hot node, and uses the gravity of the casting liquid for feeding. The feeding channel 12 can ensure the casting quality and feeding effect.
[0041] In the embodiment, due to the pitch angle adjustment of the blade mold 1, the feeding neck is cancelled, and the casting liquid can be effectively fed during the solidification process to prevent defects such as shrinkage holes and shrinkage. The effective control of the cooling process of the casting is realized, so that the chill and the chill sand are not needed.
[0042] In the embodiment, the casting liquid is copper water.
[0043] The utility model cancels the feeding neck needed by the conventional casting system to perform casting, the chill and the chill sand, thereby simplifying the casting process and possibly improving the production efficiency and the casting quality.
[0044] The utility model simplifies the casting process, reduces the tooling cost and the labor cost, improves the casting yield and the quality stability, reduces the scrap rate, and improves the production efficiency.
