Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting technology, specifically to a production equipment for high-temperature ceramic powder for aluminum alloy casting. Background Technology

[0002] With the rapid development of aerospace, automotive, and other industries, increasingly higher demands are being placed on the performance and quality of aluminum alloy castings. Traditional aluminum alloy casting processes face numerous problems when producing complex thin-walled castings, such as easy deformation, poor dimensional accuracy, and low surface finish. Ceramic mold casting, as a precision casting technology, offers advantages such as high dimensional accuracy, low surface roughness, high refractoriness, and stable high-temperature performance. It can be used to cast various alloys, and the production equipment is simple, requiring less investment and yielding quick results. Its working surface exhibits high thermal stability, exhibiting minimal deformation at high temperatures, enabling the casting of heavy, high-precision parts, and boasting a long mold lifespan. High-temperature ceramic powder is one of the key materials in ceramic mold casting, and its quality directly affects the quality of the castings. Therefore, developing efficient and stable high-temperature ceramic powder production equipment specifically for aluminum alloy casting is of great significance. This equipment must possess characteristics such as high precision, strong stability, high automation, low energy consumption, and environmental friendliness to meet the modern industrial requirements for high-quality, high-efficiency, and complex-shaped aluminum alloy castings.

[0003] Patent document CN213726034U discloses a high-temperature resistant ceramic glaze production device with storage function, including a mixing tank and a transport seat welded together. The mixing tank is equipped with a mixing mechanism, and feeding pipes are fixedly connected to both sides of the top wall of the mixing tank. A discharge trough communicating with the inner cavity is opened in the center of the bottom wall of the mixing tank. The discharge trough is equipped with mounting seats welded to both sides of the inner wall of the mixing tank. The transport seat is equipped with a transport mechanism, and a collection trough is opened on one side of the bottom wall of the transport seat. Two sets of extended seats are symmetrically welded to both sides of the transport seat. This high-temperature resistant ceramic glaze production device with storage function, through the setting of mounting seats, a second motor, a second drive shaft, and crushing blades, has two sets of second motors driving four sets of crushing blades to rotate.

[0004] Although the aforementioned application document describes a transportation mechanism installed inside the transportation seat, with the third motor of the transportation mechanism driving the conveyor belt to run, allowing the evenly arranged collectors on it to quantitatively collect and orderly deliver the ceramic glaze, there are dead zones at the bottom during use, resulting in a low mixing rate.

[0005] Therefore, a special high-temperature ceramic powder production equipment for aluminum alloy casting is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a special high-temperature ceramic powder production equipment for aluminum alloy casting, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a mixing tank, wherein the top of the mixing tank is equipped with a stirring device for improving the mixing rate of the mixing tank;

[0008] The stirring device includes a motor, which is fixedly connected to the top of the stirring tank. A first rotating rod is rotatably connected to the top of the inner wall of the stirring tank via a bearing. A drive rod is fixedly connected to the bottom of the first rotating rod. A vertical plate is fixedly connected to the bottom of the inner wall of the stirring tank. A second rotating rod is rotatably connected to the side of the vertical plate via a bearing. A rotating block is fixedly connected to the outer wall of the second rotating rod. A torsion spring is fixedly connected to the back of the rotating block. A connecting rod is fixedly connected to the side of the second rotating rod. A connecting plate is hinged to the side of the connecting rod. A flap is hinged to the side of the connecting plate. A transmission assembly for driving the motor and the first rotating rod is assembled on the top of the stirring tank.

[0009] Preferably, the transmission assembly includes a first bevel gear, which is fixedly connected to the side of the motor output end. The first rotating rod extends movably through the mixing tank and extends upwards through the top. A second bevel gear is fixedly connected to the top of the first rotating rod, and the first bevel gear and the second bevel gear mesh with each other.

[0010] Preferably, a temperature measuring gauge is fixedly connected to the top of the mixing tank, and a discharge pipe is fixedly connected to the side of the mixing tank.

[0011] Preferably, a stirring rod is fixedly connected to the outer wall of the first rotating rod, the two ends of the torsion spring are respectively fixedly connected to the side of the vertical plate and the side of the rotating block, and the flap is hinged to the side of the vertical plate.

[0012] Preferably, the top of the mixing tank is equipped with a reciprocating device for intermittent discharge.

[0013] Preferably, the reciprocating device includes a fixed rod, which is fixedly connected to the side of the first bevel gear. A support plate is fixedly connected to the top of the mixing tank. The fixed rod is rotatably connected to the side of the support plate via a bearing. A first movable rod is fixedly connected to the side of the fixed rod. A second movable rod is hinged to the side of the first movable rod. A baffle is hinged to the side of the second movable rod.

[0014] Preferably, a material box is fixedly connected to the top of the mixing tank, and the baffle is slidably connected to the inner wall of the material box.

[0015] Compared with the prior art, this utility model provides a special high-temperature ceramic powder production equipment for aluminum alloy casting, which has the following beneficial effects:

[0016] First, the linkage of components such as the drive rod ultimately drives the flap to rotate clockwise. The key effect of this action is to flip the raw material at the top of the flap to the mixing area of ​​the stirring rod, so that the raw material can be fully mixed and the mixing rate can be improved. This ensures the quality uniformity of the high-temperature ceramic powder, which is very important for the quality stability and performance consistency of the ceramic powder in the subsequent aluminum alloy casting process.

[0017] Second, after adding raw materials to the material box, the first bevel gear drives the rotation of a series of components, including the fixing rod, causing the baffle to move backward. When the baffle moves, the raw materials can fall from the top of the mixing tank into the interior, achieving intermittent feeding and avoiding the difficulty of mixing or uneven mixing caused by adding too much raw material at once.
