Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal casting technology, and in particular to a metal casting drying device. Background Technology
[0002] Metal castings are produced by melting metal into liquid and pouring it into a mold, followed by cooling, solidification, and cleaning. Residual moisture in the casting or core evaporates rapidly during the pouring of the high-temperature molten metal, generating a large amount of gas. This can lead to porosity, slag inclusions, or backflow, severely affecting the density of the casting. Alternatively, before applying anti-rust paint, the casting surface needs to be cleaned and dried to ensure the adhesion and durability of the paint film. Therefore, drying can reduce defects such as pinholes and micro-wrinkles caused by moisture during anti-rust paint application. A dried casting can better accept the coating, thus improving the anti-rust effect and the service life of the coating.
[0003] A search revealed a Chinese patent with publication number CN220288058U, which discloses a drying device for metal castings. Although the patent uses a drive motor to rotate a connecting rod, thereby rotating the fixed brackets at both ends of the connecting rod, making the metal castings suspended on the hooks heat more evenly during drying, the inner side of the casting remains inside, making it impossible to achieve effective, fast, and even drying. Relying solely on heating tubes for drying is insufficient to achieve rapid drying.
[0004] In order to better achieve the function of rapid and uniform drying of plate-shaped and strip-shaped metal castings and improve the core technology competitiveness, this application proposes a new implementation scheme for a metal casting drying device that is different from the existing technology.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-5A metal casting drying device includes a drying box 1. A motor 3 is bolted to the top outer wall of the drying box 1. A rotating rod 4 is bolted to the output end of the motor 3 through the top of the drying box 1. A first mounting plate 5 is bolted to the top of the outer circumference of the rotating rod 4, and a second mounting plate 501 is bolted to the bottom of the outer circumference of the rotating rod 4. The rotating rod 4 rotates under the drive of the motor 3, thereby driving the first mounting plate 5 and the second mounting plate 501 to rotate, which in turn drives the metal plate to rotate, thus rotating and drying the metal plate.
[0025] Multiple sleeves 6 are rotatably inserted into both the first mounting plate 5 and the second mounting plate 501. A slide rod 7 is slidably inserted into one end of each sleeve 6. Multiple mounting holes 601 are provided on one side of each sleeve 6. A first fixing bolt 602 is threaded into the mounting hole 601. One end of the first fixing bolt 602 abuts against the slide rod 7. The other end of the slide rod 7 is provided with a clamping mechanism. Adjusting the length of the slide rod 7 inserted into the sleeve 6 adjusts the distance between the clamping mechanisms on the first mounting plate 5 and the second mounting plate 501. Then, tightening the first fixing bolt 602 fixes the slide rod 7 so as to clamp metal plates of different lengths.
[0026] The top of the sleeve 6 on the first mounting plate 5 is keyed to a gear 8. A connecting plate 11 is welded to the top inner wall of the drying box 1. An internal gear ring 12 is welded to the bottom of the connecting plate 11. The internal gear ring 12 meshes with the gear 8. Driven by the first mounting plate 5, the internal gear ring 12 rotates. Then, under the action of the internal gear ring 12 meshing with the gear 8, the sleeve 6 and the slide rod 7 rotate, thereby causing the clamped metal plate to rotate, and thus adjusting the drying surface of the metal plate.
[0027] A heating chamber 13 is bolted to the top outer wall of the drying oven 1. Two fans 14 are embedded in one side of the heating chamber 13. A heating tube 15 is bolted inside the heating chamber 13. Two air inlet pipes 16 are sealed and inserted into the other side of the heating chamber 13. A distribution box 17 is snapped into the other end of the air inlet pipe 16. The two distribution boxes 17 are respectively snapped into the two sides of the drying oven 1. Multiple air outlets 18 are sealed and inserted into one side of the distribution box 17. Under the action of the fans 14, the gas is drawn into the heating chamber 13. Then, the gas is heated by the heating tube 15. Then, the hot air is input into the distribution box 17 through the air inlet pipe 16 and blown onto the metal plate from the air outlets 18, thereby drying the metal plate.
[0028] The clamping mechanism includes a first clamping block 10 and a second clamping block 1001. One end of the slide rod 7 is fixed to a mounting bracket 9 by bolts. The first clamping block 10 is adhered to the inner wall of one side of the mounting bracket 9. A second fixing bolt 1002 is threaded into one side of the mounting bracket 9. The second clamping block 1001 is rotatably sleeved on one end of the second fixing bolt 1002. Tightening the second fixing bolt 1002 causes the second clamping block 1001 to move closer to the first clamping block 10, thereby clamping the two ends of the metal plate or metal strip.
[0029] A sealing door 2 is rotatably connected to one side of the drying oven 1. An observation window 201 is embedded in one side of the sealing door 2 to observe the drying status of the metal plate. A control panel 101 is fixed to one side of the outer wall of the drying oven 1. The control panel 101 is electrically connected to the motor 3, the fan 14 and the heating tube 15. The top of the drying oven 1 is provided with multiple air vents.
[0030] The working principle of this embodiment is as follows: In use, first, open the sealing door 2, then adjust the length of the slide rod 7 and the sleeve 6 to adjust the distance between the clamping mechanisms on the first mounting plate 5 and the second mounting plate 501, then tighten the first fixing bolt 602 to fix the slide rod 7 so as to clamp metal plates of different lengths. Next, place the metal plate between the first mounting plate 5 and the second mounting plate 501, with one end of the metal plate located between the first clamping block 10 and the second clamping block 1001. Then, tighten the second fixing bolt 1002 to move the second clamping block 1001 closer to the first clamping block 10, thereby clamping both ends of the metal plate.
[0031] Then, the sealing door 2 is closed, and the fan 14 and heating tube 15 are started by controlling the control panel 101. Under the action of the fan 14, the gas is drawn into the heating box 13. Then, the gas is heated by the heating tube 15. Then, the hot air is input into the distribution box 17 through the air inlet pipe 16, and then blown onto the metal plate from the air outlet 18, thereby drying the metal plate. The dried gas is discharged from the air outlet. During the drying process, the motor 3 is started by controlling the control panel 101. Under the drive of the motor 3, the rotating rod 4 is rotated, thereby driving the first mounting plate 5 and the second mounting plate 501 to rotate, and then driving the metal plate to rotate, thus rotating and drying the metal plate. At the same time, the internal gear ring 12 is rotated under the drive of the first mounting plate 5. Then, under the action of the internal gear ring 12 meshing with the gear 8, the sleeve 6 and the slide rod 7 are rotated, thereby driving the clamped metal plate to rotate, thereby adjusting the drying surface of the metal plate, so as to better dry the metal plate.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
