Abstract
Description
Technical Field
[0001] The invention relates to the technical field of die-casting machines, in particular to an automatic feeder for aluminum alloy die-casting and gravity casting. Background Art
[0002] A die-casting machine is a machine used for pressure casting, including a hot press chamber and a cold press chamber, which are later divided into two types: vertical and horizontal. The die-casting machine hydraulically injects the molten metal into the mold under pressure for cooling and forming. After the mold is opened, a solid metal casting can be obtained. It was originally used for die-casting lead type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and home appliances, die-casting technology has achieved extremely rapid development. However, in the existing technology, there is often a risk of explosion in the furnace when die-casting aluminum ingots or aluminum bars, and due to the lack of preheating, a lot of melting costs are increased, which is not conducive to the interests of the enterprise itself. For this reason, we propose an automatic feeder for aluminum alloy die-casting and gravity casting. Summary of the invention
[0003] The object of the present invention is to provide an automatic feeder for aluminum alloy die casting and gravity casting to solve the problems raised in the above background technology.

[0005] Preferably, the bottom of the base is fixedly connected to a frame on all four sides, and the bottom of the frame is connected to an anti-slip pad by adhesive.
[0006] Preferably, the clamping arm is also provided with a screw motor and a slider bearing, and the screw motor and the slider bearing are both arranged on the top of the clamp.
[0007] Preferably, an electric control box is also provided on the back of the feeder body, and the electric control box includes a human-machine operation interface, a display and a PLC controller.
[0008] Preferably, there are multiple aluminum material lowering travel switches, and the distance between every two adjacent aluminum material lowering travel switches is the same.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] The aluminum ingot or aluminum rod of the present invention is melted by slowly descending in multiple stages, and high-temperature preheating is performed before each descent to ensure the stable quality of the die-cast product. The heat emitted from the furnace mouth is used to preheat the aluminum ingot or aluminum rod before feeding, which saves a lot of melting costs. At the same time, a feeding method of preheating first and then feeding is adopted, which effectively reduces the labor intensity and completely solves the risk of explosion when the water-containing material is fed into the furnace. The fully automatic feeding method is equipped with a self-locking device, which is stable and safe when feeding and will not cause the crucible to break. At the same time, no matter how long the material is, it can be used by adjusting the material receiving platform, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the feeder body 1 is provided with an aluminum material placement platform 11, which can be used to place aluminum ingots or aluminum bars, and can automatically complete the rotation and positioning of the aluminum ingots or aluminum bars under the drive of the rotating motor 12, and the aluminum material placement platform 11 An aluminum material positioning switch 10 is arranged on the top, a processed material 16 is placed on the top of the aluminum material placement platform 11, and a clamp 9 is arranged at the middle end of the feeder body 1, and a clamping arm 8 is arranged on the top of the clamp 9, and the clamping arm 8 is also provided with a screw motor and a slider bearing, and the screw motor and the slider bearing are all arranged on the top of the clamp 9, and the clamp 9 is also connected to a cylinder ejection mechanism 7, and the cylinder ejection mechanism 7 is also connected to a clamping cylinder 6, and a forward and backward motor 2 is arranged at the right end of the top of the feeder body 1, and an up and down travel motor 3 is arranged on the upper end of the top of the feeder body 1, and an up and down travel screw 4 is arranged on the left side of the up and down travel motor 3. The feeder body 1 can be adjusted up and down by the up and down travel motor 3 and the up and down travel screw 4 according to the length of the aluminum ingot or aluminum rod to achieve the required appropriate height. At the same time, an aluminum material descending stroke switch 5 is also arranged on the left side of the up and down travel screw 4, and the number of aluminum material descending stroke switches 5 is multiple, and the distance between every two adjacent aluminum material descending stroke switches 5 is the same.
[0017] When in use, a rotating motor 12 is provided to drive the aluminum material placing platform 11 for placing aluminum ingots or aluminum bars to rotate. The aluminum material placing platform 11 is provided to place aluminum ingots or aluminum bars, and the rotation and positioning of the aluminum ingots or aluminum bars can be automatically completed under the drive of the rotating motor 12. The automatic rotation and positioning of the aluminum ingots or aluminum bars is completed by a gear plate 14 and the rotating motor 12 installed under the frame 13. The gear plate 14 is punched with a corresponding number of holes for placing the aluminum ingots or aluminum bars. The positioning switch 10 senses the positioning. When the device detects that the aluminum ingot and aluminum rod are clamped and rise to the highest position, the rotating motor 12 drives the gear plate 14 to rotate. When the next aluminum material positioning switch 10 detects the hole position on the gear plate 14, it stops rotating and waits for the next clamping signal. The clamping action is when the device detects that the aluminum liquid level in the furnace is low.

This action is performed N times, and finally there is a little aluminum ingot or aluminum rod left. The clamping cylinder 6 is released, and the remaining very small aluminum rod or aluminum ingot falls into the furnace. While these actions are being performed, the aluminum material placement base 11 of the feeder body 1 rotates and has positioned the position where the next aluminum ingot or aluminum rod is to be clamped, waiting for the next signal of low aluminum liquid level in the furnace and clamping the material again. The feeder body 1 can be adjusted up and down by the up and down walking motor 3 and the up and down walking screw 4 according to the length of the aluminum ingot or aluminum rod to achieve the required appropriate height.
