Description

Technical Field

[0001] The utility model relates to the technical field of casting devices for casting sheets, in particular to a casting device for a metal solution as a raw material for casting sheets. Background Art

[0002] As an important permanent magnet material, NdFeB quick-setting alloy is experiencing increasing market demand. Only by continuously improving the performance and quality of cast sheets can we meet the increasingly stringent requirements of industrial applications. Generally, when processing and manufacturing NdFeB quick-setting alloy cast sheets, molten metal is poured through a casting device through a rotating process. Centrifugal force causes the molten metal to disperse into thin sheets in a mold, and then the metal sheet is completed by cooling.

[0003] However, the existing casting device has an excessive flow rate of molten liquid during casting, resulting in an overly fast casting speed, which makes it difficult to adjust the casting speed well. In the process of quickly introducing the molten liquid into the mold, it is difficult to evenly distribute the molten liquid, which affects the uniformity of the thickness of the cast sheet after molding and reduces the product qualification rate.

[0011] Beneficial effects of the utility model:

[0012] 1. When the molten metal is cast by swinging, the first gear is driven to rotate by starting the second drive motor, so that the discharge hopper arranged at the bottom of the feed hopper is rotated, so that the molten liquid in the discharge hopper can be slowly thrown into the forming mold from multiple material mixing ports, so that the molten metal is dispersed into thin flakes in the mold under the action of centrifugal force. At the same time, starting the first drive motor can repeatedly drive the material mixing port at the bottom of the discharge hopper to move left and right on the inside of the shell, expanding the range of the multiple material mixing ports, allowing the molten liquid to effectively enter the forming mold, avoiding the solution entering the forming mold too quickly, thereby effectively controlling the molten liquid casting speed and improving the uniformity of the casting sheet thickness.

The convex plate 44 is connected to the other side of the movable plate 43. The cam 42 is connected to one end of the output shaft of the drive motor 41 and cooperates with the convex plate 44.

[0023] Specifically, a plurality of springs 45 can be provided, and the driving motor 1 41 is installed on the inner side or the outer side of the vibration shell 4.

[0030] Specifically, when the molten metal is cast into sheets, the forming mold is first placed under the discharge hopper 3 and calibrated, and the molten liquid is then dropped into 70 through the discharge port of the furnace body, and then introduced into the feed hopper 2 through 70, and thus introduced into the inside of the discharge hopper 3, and the second drive motor 71 is started to drive the first gear 72 to rotate, so that the discharge hopper 3 set at the bottom of the feed hopper 2 rotates, so that the molten liquid in the discharge hopper 3 can be slowly thrown into the forming mold from multiple material mixing ports 30, so that the molten metal is dispersed into thin sheets into the mold under the action of centrifugal force, and at the same time, the drive motor 1 41 is started, which can repeatedly drive the material mixing port 30 at the bottom of the discharge hopper 3 to move left and right on the inside of the shell 1, thereby expanding the range of multiple material mixing ports 30, allowing the molten liquid to effectively enter the forming mold, and avoiding the solution from entering the forming mold too quickly, thereby effectively controlling the casting speed of the molten liquid and improving the uniformity of the thickness of the casting sheet.
