DETAILED DESCRIPTION

[0024] See also Figure 1-3 A feeding device for magnesium alloy die-casting comprises a mounting plate 1, a storage box 2 is fixedly mounted on the top of the mounting plate 1, and the storage box 2 is a hollow structure with an opening on the top, one side wall of the storage box 2 is provided with two upper and lower discharge ports 3 and a lower discharge port 4 spaced apart from each other, a spring door 5 is provided in the upper discharge port 3, a baffle assembly 7 is provided in the storage box 2 near the lower position of the upper discharge port 3, a push port 8 is provided on the other side wall of the storage box 2, and the upper discharge port 3 matches the push port 8, a push assembly 9 is provided on the storage box 2 near the push port 8, and a driving assembly 10 for driving the push assembly 9 to work is provided on the mounting plate 1.

[0025] The baffle assembly 7 includes a baffle 71 movably disposed in the storage box 2 , and when the baffle 71 is in a horizontal position, the top of the baffle 71 is flush with the bottom of the upper discharge port 3 .

[0026] One end of the baffle 71 is hinged in the material storage box 2 , and the other end of the baffle 71 can be longitudinally rotated around the hinge point, and the size of the baffle 71 is adapted to the inner cavity of the material storage box 2 .

[0027] A slot 72 is vertically formed on the inner wall of the material storage box 2 below the hinged end of the baffle 71 , and a first motor 73 is fixedly mounted on the top of the slot 72 .

[0028] The power output end of the first motor 73 is transmission-connected with a threaded rod 74 , and the bottom end of the threaded rod 74 is rotationally connected to the bottom of the empty slot 72 .

[0029] A threaded sleeve 75 is threadedly connected to the threaded rod 74 , and a connecting rod 76 is hinged between the threaded sleeve 75 and the bottom of the baffle 71 .

[0030] A guide groove 77 is vertically formed on one of the inner side walls of the hollow groove 72 . A guide block 78 is slidably connected in the guide groove 77 . One end of the guide block 78 is fixedly connected to the threaded sleeve 75 .

[0031] When granular magnesium alloy material needs to be added, the first motor is started, and the power output end of the first motor 73 drives the threaded rod 74 to rotate. Since the threaded sleeve 75 is threadedly connected to the threaded rod 74, and the guide block 78 and the guide groove 77 limit the rotation of the threaded sleeve 75, the threaded sleeve 75 will move up and down along the threaded rod 74.

[0032] When the threaded sleeve 75 moves downward, the baffle 71 is driven to rotate downward around the hinge point through the connecting rod 76, so that the material placed on the baffle 71 flows to the bottom of the storage box 2. When the threaded sleeve 75 moves upward, the baffle 71 will rotate upward around the hinge point, and the baffle 71 will gradually move to a horizontal state to close the material discharge.

[0033] This design realizes the automatic lifting and lowering of the baffle 71, thereby controlling the size and closing of the opening of the baffle 71, thereby realizing the control of the feeding speed and feeding amount. At the same time, the cooperation of the threaded rod 74 and the threaded sleeve 75 can ensure that the lifting and lowering of the baffle 71 is smooth and reliable; in addition, the design of the guide block 78 and the guide groove 77 can ensure the accurate movement direction of the threaded sleeve 75, avoiding problems such as jamming or offset.

[0034] The pushing assembly 9 includes a limiting tube 91 fixedly mounted on the storage box 2 , and the limiting tube 91 is connected to the pushing port 8 , a pushing block 92 is slidably arranged in the limiting tube 91 , and the size of the pushing block 92 is adapted to the pushing port 8 .

[0035] The driving assembly 10 comprises a vertical plate 101 fixedly mounted on the top of the mounting plate 1 , a second motor 102 is fixedly mounted on the vertical plate 101 , and a power output end of the second motor 102 is drivingly connected to a rotating disk 103 .

[0036] A transmission rod 104 is eccentrically hinged on the rotating disk 103 , and one end of the transmission rod 104 away from the rotating disk 103 is hinged to the pushing block 92 .

[0037] When it is necessary to push the block-shaped magnesium alloy ingot material, the second motor 102 is started, and the power output end of the second motor 102 is connected to the rotating disk 103, so that the rotating disk 103 starts to rotate, and the transmission rod 104 eccentrically hinged on the rotating disk 103 moves with the rotation of the rotating disk 103. Since the end of the transmission rod 104 away from the rotating disk 103 is hinged to the pushing block 92, the movement of the transmission rod 104 drives the pushing block 92 to slide in the limiting tube 91, and the pushing block 92 moves toward the pushing port 8 to push all the magnesium alloy ingots out of the pushing port 8. According to needs, the second motor 102 can rotate continuously or periodically, so as to realize the continuous or intermittent pushing action of the pushing block 92, and then realize the control of the feeding speed and feeding amount.

[0038] A material guiding inclined plate 11 is fixedly connected to the inner wall of the bottom of the material storage box 2 , and the inclined bottom end of the material guiding inclined plate 11 is level with the bottom end of the lower discharge port 4 .

[0039] With such a design, the material can be guided from the bottom of the storage box 2 to the lower discharge port 4 by setting the material guide inclined plate 11, thereby ensuring smooth discharge of the material.

[0040] A controller 12 is fixedly mounted on the top of the mounting plate 1 , and the first motor 73 and the second motor 102 are both electrically connected to the controller 12 .

[0041] By designing in this way, by electrically connecting the first motor 73 and the second motor 102 to the controller 12, not only can centralized control and management of the feeding device be achieved, but the controller 12 can also coordinate the starting, stopping and running speed of the motors to ensure the accuracy and stability of the feeding process.

[0042] The controller 12, the first motor 73 and the second motor 102 are prior art and can be purchased. They are prior art and are components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0043] When the feeding device for magnesium alloy die-casting is used, block-shaped magnesium alloy ingot materials or granular magnesium alloy granular materials are placed inside the storage box 2. When the block-shaped magnesium alloy ingot materials are fed or when the block-shaped magnesium alloy ingot materials need to be pushed, the second motor 102 is started, and the power output end of the second motor 102 is connected to the rotating disk 103 in a transmission manner, so that the rotating disk 103 starts to rotate, and the transmission rod 104 eccentrically hinged on the rotating disk 103 moves with the rotation of the rotating disk 103. Since the end of the transmission rod 104 away from the rotating disk 103 is hinged to the pushing block 92, the movement of the transmission rod 104 drives the pushing block 92 to slide in the limiting tube 91, and the pushing block 92 moves toward the pushing port 8 to push all the magnesium alloy ingots out of the pushing port 8. According to needs, the second motor 102 can rotate continuously or periodically, thereby realizing the continuous or intermittent pushing action of the pushing block 92, and then realizing the adjustment of the feeding speed.

[0044] When granular magnesium alloy material is added, the first motor 73 is controlled to rotate by the controller 12, and the power output end of the first motor 73 drives the threaded rod 74 to rotate. Since the threaded sleeve 75 is threadedly connected to the threaded rod 74, and the guide block 78 and the guide groove 77 limit the rotation of the threaded sleeve 75, the threaded sleeve 75 will move up and down along the threaded rod 74.

[0045] When the threaded sleeve 75 moves downward, the baffle 71 is driven to rotate downward around the hinge point through the connecting rod 76, so that the material placed on the baffle 71 flows to the bottom of the storage box 2, and is discharged from the discharge port to the outside through the material guide inclined plate 11.

[0046] When the threaded sleeve 75 moves upward, the baffle 71 will rotate upward around the hinge point, and the baffle 71 will gradually move to a horizontal state to close the feeding, thereby controlling the size and closing of the opening of the baffle 71 to achieve control of the feeding speed and feeding amount.

[0047] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
