In addition, during the continuous casting operation, dust and impurities will inevitably accumulate in the bottom mold groove, thereby affecting the casting quality of the aluminum ingot. Therefore, it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides an aluminum ingot continuous casting device, comprising a casting mechanism 1, a plurality of evenly distributed molding regulating mechanisms 2 are arranged on the side of the casting mechanism 1, a vent hole 3 is opened on the front of the casting mechanism 1, a transmission shaft 7 is installed on the back of the casting mechanism 1, the vent hole 3 is connected to an air pump through a hose, and the transmission shaft 7 is fixedly connected to the output shaft of the motor;

[0022] The molding regulating mechanism 2 includes a molding groove 21 opened on the side of the casting mechanism 1, and a gas collecting cavity 22 located on the back of the vent hole 3 is opened in the middle of the casting mechanism 1. Each molding groove 21 is connected to the gas collecting cavity 22 through a dispersion cavity 23 opened inside the casting mechanism 1. A bottom mold piston plate 24 is movably arranged inside the molding groove 21, and a solenoid valve 27 is arranged at one end of the dispersion cavity 23 close to the gas collecting cavity 22. A piston shaft 25 is movably arranged at one end of the dispersion cavity 23 close to the bottom mold piston plate 24, and a connecting rod 26 is fixedly connected between the piston shaft 25 and the bottom mold piston plate 24.

[0023] The transmission shaft 7 and the casting mechanism 1 can drive a number of continuously distributed molding grooves 21 to rotate continuously, so that the position of the bottom mold piston plate 24 can be adjusted in real time with the cooperation of the solenoid valve 27 and the air pump, so that the material addition and casting and the material removal and demoulding can be carried out continuously, and then with the cooperation of the several molding grooves 21, continuous and efficient casting can be completed.

[0024] Among them, a plurality of molding grooves 21 are continuously distributed on the side of the casting mechanism 1, and the shapes and sizes of the plurality of molding grooves 21 are the same;

[0025] Driven by the transmission shaft 7 and the casting mechanism 1 , the plurality of molding grooves 21 can be continuously rotated to avoid mutual influence between demoulding and casting, thereby improving the casting efficiency and achieving the effect of continuous casting.

[0026] Among them, the dispersion chamber 23 and the electromagnetic valve 27 correspond to the forming groove 21 one by one, and the vent hole 3 is connected with several dispersion chambers 23 at the same time through the gas collecting chamber 22;

[0027] By controlling the opening and closing time of a corresponding solenoid valve 27, the amount of gas pumped into a corresponding dispersion chamber 23 by the air pump can be changed, and then the initial positions of the piston shaft 25, the connecting rod 26 and the bottom mold piston plate 24 can be changed, thereby changing the initial depth of the forming groove 21, thereby achieving the effect of adjusting the height size of the cast aluminum ingot.

[0028] The bottom mold piston plate 24 is sealed and clamped inside the molding groove 21, the piston shaft 25 is sealed and sleeved inside the dispersion chamber 23, and the connecting rod 26 is movably sleeved inside the casting mechanism 1;

[0029] Due to the setting of the bottom mold piston plate 24, not only can an adjustable bottom mold be formed with the cooperation of the molding groove 21 to complete the material pouring, but also the dust or impurities inside the molding groove 21 can be discharged when the bottom mold piston plate 24 moves along the inside of the molding groove 21 for demoulding.

[0030] The maximum distance that the piston shaft 25 moves along the dispersion chamber 23 is the same as the maximum distance that the bottom mold piston plate 24 moves along the molding groove 21;

[0031] Due to the opening of the solenoid valve 27, the gas continuously injected into the dispersion chamber 23 by the air pump can push the piston shaft 25 to move continuously, and then with the cooperation of the connecting rod 26, the bottom mold piston plate 24 can move continuously along the inside of the molding groove 21, ensuring that the bottom mold piston plate 24 can completely push the cast aluminum ingot to the outside of the molding groove 21 to complete demolding.

[0032] Among them, a positioning frame 4 is fixedly connected to both the front and rear sides of the casting mechanism 1, and the positioning frame 4 and the casting mechanism 1 share the same axis. A support seat 5 is arranged below the casting mechanism 1, and the tops of the front and rear ends of the support seat 5 are respectively located directly below the front and rear positioning frames 4. The side of the positioning frame 4 is movably connected with a ball 6, and the ball 6 is movably installed on the top of the support seat 5;

[0033] Under the action of the ball 6, the positioning frame 4 and the support seat 5 can be movably connected. At the same time, due to the arc shape at the top of the support seat 5, the positioning frame 4 can limit the casting mechanism 1 to a certain extent to prevent it from shaking left and right. At the same time, when the press is pressed down, the overall strength of the casting mechanism 1 can be greatly improved with the cooperation of the positioning frame 4 and the support seat 5, avoiding the situation where the casting mechanism 1 is damaged by excessive pressure.

[0034] The working principle and use process of this utility model:

[0035] The casting raw material is poured into the interior of a molding groove 21 that rotates to the top, and then the press is started to press the top mold down, and the die casting is completed under the cooperation of the molding groove 21 and the bottom mold piston plate 24. Then the press lifts the top mold to make it leave the molding groove 21. At this time, the molding groove 21 that has completed the casting continues to rotate under the drive of the transmission shaft 7, and the molding groove 21 behind it rotates to the top and repeats the above-mentioned feeding and die casting process to complete continuous casting. The molding groove 21 after the die casting drives the formed aluminum ingot to rotate downward, and under the cooperation of the corresponding electromagnetic valve 27, the piston shaft 25, the connecting rod 26 and the bottom mold piston plate 24 push the aluminum ingot to leave the molding groove 21, and the demoulding is completed, so that the molding groove 21 can be driven by the transmission shaft 7 and the casting mechanism 1 to rotate to the top again for feeding and casting;

[0036] By controlling the opening and closing time of a corresponding solenoid valve 27, the amount of gas pumped into a corresponding dispersion chamber 23 can be changed, and then the initial positions of the piston shaft 25, the connecting rod 26 and the bottom mold piston plate 24 can be changed, thereby changing the initial depth of the molding groove 21.
