[0002] In the casting production of rare earth silicon alloys, the molten rare earth silicon alloy contains active rare earth elements, which are very easy to react with oxygen in the air during the casting process, causing oxidation loss of alloy components and seriously affecting product quality and performance.

[0003] Traditional casting equipment relies solely on a simple casting ladle outlet to guide the molten metal, lacking a continuous and effective inert gas protection structure after the molten metal flows out. Molten metal oxidation is difficult to avoid, and the imperfect flow guidance and sealing design further affects the rapid prototyping efficiency and finished product quality stability of rare earth silicon alloys. Utility Model Content

[0004] To address this issue, this invention provides a rapid prototyping rare earth silicon alloy casting production device to overcome the problems of existing casting devices that rely solely on a simple casting ladle outlet to guide the molten liquid, lacking a continuous and effective inert gas protection structure after the molten liquid flows out, making molten liquid oxidation difficult to avoid. At the same time, the imperfect flow guidance and sealing design further affects the rapid prototyping efficiency and the stability of the finished product quality of rare earth silicon alloys.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a rapid prototyping rare earth silicon alloy casting production device includes a casting ladle outlet 1 for guiding the rare earth silicon alloy molten metal out of the casting ladle. The casting ladle outlet 1 is inserted into an argon gas protection component and is located at the upper end of a melting channel 5. The melting channel 5 is located at the lower end of the argon gas protection component. The argon gas protection component and the casting ladle outlet 1 are detachably connected by bolts. A sealing component is fitted on the outside of the argon gas protection component, which completely covers the argon gas protection component and the melting channel 5. Argon gas is sprayed out from the argon gas protection component, forming an inert gas protective atmosphere on the surface of the molten metal to prevent the molten metal from oxidizing after contacting air after flowing out of the casting ladle outlet, thus ensuring the stability of the alloy composition.

[0023] The argon gas protection component includes a first argon ring 2, a second argon ring 3, and an orifice plate 4. The first argon ring 2 is fixed to the upper end of the second argon ring 3 to form an annular gas path structure distributed vertically. An orifice plate 4 is fixed inside between the first argon ring 2 and the second argon ring 3. The orifice plate 4 is fitted onto the casting ladle outlet 1, which not only initially disperses and evenly distributes the argon gas flow, but also helps to fix the relative position of the casting ladle outlet 1.

[0024] The inner side of the first argon ring 2 is provided with multiple fine vent holes, from which argon gas can be ejected to form a preliminary annular gas curtain to protect the molten liquid flowing out of the casting ladle outlet 1. The outer side of the second argon ring 3 is provided with multiple elongated oblique hole groups, each of which includes multiple elongated oblique holes. The oblique hole design creates a directional airflow when the argon gas is ejected, enhancing the removal of air around the argon gas protection components and the sealing effect.

[0025] The sealing assembly includes a sealing cover 7 and a base plate 8. The sealing cover 7 covers the argon gas protection assembly and the melt channel 5 to form a relatively sealed space and reduce the intrusion of external air. The bottom of the sealing cover 7 is threaded to the base plate 8, and the base plate 8 is fixedly sleeved on the outside of the melt channel 5.

[0026] Multiple baffle groups are fixed on the inner side of the sealing cover 7. The baffle groups are set in correspondence with the elongated oblique hole groups. Each baffle group includes multiple baffles 9. The multiple baffles 9 are fixed on the inner side of the sealing cover 7 from top to bottom. Each baffle 9 is set with a different length, which can guide and disperse the argon gas ejected from the elongated oblique holes in stages, so that the argon gas is more evenly distributed in the sealing cover 7. At the same time, it slows down the argon gas escape rate and prolongs the protection time of the molten liquid.

[0027] Multiple observation holes are fixed on the top of the sealing cover 7, and transparent high-temperature resistant glass is fixed inside the observation holes to facilitate observation of the internal condition of the sealing cover 7.

[0028] A chute 6 is fixed to the side of the melting channel 5. The molten liquid flows from the chute 6 and eventually enters the target position to complete the casting process.

[0029] Actual work process:

[0030] In use, argon gas is connected to the argon gas protection component through an external connection pipe. A portion of the argon gas is ejected from the vent holes on the inner side of the first argon ring 2, forming a first annular inert gas curtain around the molten liquid flowing out of the casting ladle outlet 1, which initially blocks the contact between air and molten liquid.

[0031] Another portion of argon gas is ejected from the elongated oblique hole group on the outer side of the second argon ring 3. The ejected argon gas is guided and dispersed by the corresponding partition group (partitions 9 of different lengths) inside the sealing cover 7, forming a second layer of inert gas atmosphere in the space between the sealing cover 7 and the argon gas protection component and the melting channel 5, further isolating the outside air.

[0032] After the rare earth silicon alloy molten liquid in the casting ladle flows out of the casting ladle outlet 1, it first enters the melting channel 5 under the protection of the first argon gas curtain. When the molten liquid flows in the melting channel 5, it is continuously in an inert gas environment created by the sealing component and the argon gas protection component to avoid oxidation from contact with air. The molten liquid flows out quickly from the chute 6 at the side end of the melting channel 5 and enters the target position to complete the molding, thus achieving effective anti-oxidation protection of the molten liquid and rapid molding guidance.

[0033] When maintenance or replacement of parts is required, the argon gas protection assembly can be separated from the casting ladle outlet 1 by loosening the bolts, and the sealing cover 7 can be opened by loosening the threaded connection between the sealing cover 7 and the base plate 8, making it convenient to operate the internal components.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
