Description

Technical Field

[0002] As we all know, metal casting refers to a metal forming processing method in which molten fluid metal is poured into a shaping mold, and the fluid metal is cooled and shaped in the mold to obtain a metal billet. After surface treatment, the metal billet obtains a metal component that meets the predetermined shape and size. This processing method can facilitate the rapid forming of components, reduce the amount of residual material during cutting, reduce metal waste, and reduce costs. In the casting process, metal often needs to add an inoculant to the fluid metal.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 3 to 5 As shown, a flow inoculation device for precision casting of the present invention comprises a first barrel 1, a second barrel 2 and a third barrel 3, the first barrel 1, the second barrel 2 and the third barrel 3 are sequentially connected and communicated, the first barrel 1 is fixedly connected to the second barrel 2, and the second barrel 2 is rotatably connected to the third barrel 3; A plurality of feed pipes 4 are obliquely arranged in the first material barrel 1, a buckle slot plate 5 is buckled at the opening of the feed pipe 4, a material guide pipe 6 is obliquely installed at the bottom of the buckle slot plate 5, and the buckle slot plate 5 is connected to the material guide pipe 6, and the outer wall of the feed pipe 4 blocks the material guide pipe 6; The outer wall of the second material barrel 2 is provided with a plurality of notches 9, and a material receiving slot plate 7 is provided in an inclined and sliding manner in the notches 9, and the material receiving slot plate 7 extends into the second material barrel 2, wherein the top of the material receiving slot plate 7 located inside the second material barrel 2 is set to an open state, and the material receiving slot plate 7 located outside the second material barrel 2 is set to a sealed cylinder state, and the bottom of the material guide pipe 6 is located in the material receiving slot plate 7, and a baffle plate 8 is provided on the top of the inner wall of the notch 9, and the bottom of the baffle plate 8 is inserted into the material receiving slot plate 7 and seals the material receiving slot plate 7; The buckle slot plate 5 is provided with a connecting rod structure, which is connected to the material receiving slot plate 7 , and a stirring structure is provided inside the third material barrel 3 .

[0019] In this embodiment, the molten fluid metal enters the feed pipe 4, and the fluid metal in the feed pipe 4 exerts a force on the buckle slot plate 5 and pushes the buckle slot plate 5 to move outward, and the guide pipe 6 moves synchronously, and the fluid in the feed pipe 4 enters the guide pipe 6 and flows downward to the receiving slot plate 7. At the same time, when the buckle slot plate 5 moves, the buckle slot plate 5 pushes the receiving slot plate 7 to move downward through the connecting rod structure, and a gap appears between the bottom of the inner wall of the receiving slot plate 7 and the bottom of the baffle 8. The inoculant flows downward through the gap, and the fluid discharged from the guide pipe 6 impacts and mixes the inoculant, thereby facilitating The inoculant is initially mixed with the fluid metal. When the fluid flow in the feed pipe 4 increases, the force acting on the buckle groove plate 5 increases, the moving distance of the buckle groove plate 5 increases, the shielding area of ​​the outer wall of the feed pipe 4 to the guide pipe 6 decreases, and the amount of fluid discharged from the guide pipe 6 increases. At this time, the gap between the receiving groove plate 7 and the baffle plate 8 increases, and the supply of the inoculant increases synchronously, thereby ensuring that the supply of the inoculant is consistent with the fluid flow, avoiding a large difference in the ratio and affecting the quality of the casting. At the same time, the downward moving distance of the receiving groove plate 7 increases, the distance between the receiving groove plate 7 and the guide pipe 6 increases, and the guide pipe 6 The impact force of the discharged fluid on the inoculant on the receiving slot plate 7 is increased, so that the increased inoculant is quickly merged with the fluid. The fluid on the receiving slot plate 7 flows downward naturally and is discharged. The fluids discharged from multiple receiving slot plates 7 impact and merge with each other and fall into the third barrel 3. The third barrel 3 is rotated, and the third barrel 3 drives the fluid to rotate. The stirring structure stirs the rotating fluid, so that the fluid and the inoculant therein are quickly merged, and the diffusion speed and uniformity of the inoculant are improved. The fluid metal and inoculant in the third barrel 3 can be discharged through the bottom opening of the third barrel 3. The inoculant is discharged into the shaping mold, thereby realizing the flow-based inoculation of the inoculant. By automatically controlling the amount of the inoculant according to the flow rate of the fluid metal, the precise batching of the inoculant can be achieved, saving the process steps of weighing the inoculant, simplifying the operation method, saving manpower, and the inoculant is in a continuous and real-time delivery state, which can facilitate the rapid fusion of the continuously delivered inoculant and the continuously flowing fluid metal. After stirring and mixing, the uniformity of the inoculant distribution can be easily improved, the inoculation effect can be improved, the gradual quality can be improved, and the time required for the diffusion of the inoculant can be shortened to improve work efficiency.
