Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1:

[0025] As Figures 1 to 3 shown, a feeding device for a die-casting machine includes a base 1. On one side of the upper surface of the base 1, there is an adjustable feeding mechanism 2. The adjustable feeding mechanism 2 includes two first side plates 21 symmetrically and slidably connected to the upper surface of the base 1. On one side of the outer surface of the first side plate 21 and near the bottom, there is a bottom plate 22 fixedly connected. On both sides of the upper surface of the bottom plate 22, two springs 23 and telescopic rods 24 are fixedly connected symmetrically in sequence. Between the tops of the spring 23 and the telescopic rod 24, there is an inclined feeding plate 25 fixedly connected. At the bottom of the inclined feeding plate 25, a vibration motor 26 is fixedly installed. On one side of the outer surface of the first side plate 21 and near the feeding mechanism 3, there is a clamping cylinder 27 fixedly installed through. The movable end of the clamping cylinder 27 is fixedly connected with a clamping plate 28. A storage groove 29 matching the clamping plate 28 is formed on the outer surface of the first side plate 21.

[0026] When feeding, the bar stock can be directly placed on the two inclined feeding plates 25 of the adjustable feeding mechanism 2, and then the vibration motor 26 is started. With the cooperation of the spring 23, the bar stock can automatically move along the inclined feeding plate 25, without the need to lift and stack the bar stock, reducing the work burden, thus solving the problem that the existing device needs to lift and stack the bar stock in the material rack, which increases the work burden. And during the movement of the bar stock, the clamping cylinder 27 can drive the clamping plate 28 to clamp the bar stock, so that the bar stock can fall in sequence, avoiding affecting the feeding mechanism 3.

[0027] Embodiment 2:

[0028] As Figure 1 、 Figure 2 and Figure 4 shown, on one side of the upper surface of the base 1, there is a feeding mechanism 3 matching the adjustable feeding mechanism 2. The feeding mechanism 3 includes two support plates 31 symmetrically and slidably connected to the upper surface of the base 1. At the top of the two support plates 31, there are second side plates 32 fixedly connected obliquely. At both ends of the second side plate 32, there are conveying rollers 33 rotatably connected through. A conveyor belt 34 is sleeved between the two conveying rollers 33. On the outer surface of the conveyor belt 34, a plurality of partition plates 35 are fixedly connected in sequence. On the outer surfaces of the adjacent two conveying rollers 33, there are a spline shaft 36 and a spline sleeve 37 fixedly connected to cooperate with each other. On the outer surface of any one of the second side plates 32, a servo motor is fixedly installed, and the output shaft of the servo motor is fixedly connected to one end of the adjacent conveying roller 33. On one side of the top of the second side plate 32, there is a guide plate 38 fixedly connected obliquely. On one side of the guide plate 38, there is a baffle 39 fixedly connected.

[0029] The bar stock on the adjustable loading mechanism 2 will automatically fall onto the conveyor belt 34 of the feeding mechanism 3. The second side plate 32 and the partition 35 are provided to continuously limit and convey the bar stock, which can not only improve work efficiency but also prevent the bar stock from falling, thus solving the problem that the existing device can only load one piece of material at a time and reduces work efficiency.

[0030] Embodiment 3:

[0031] As Figure 1 、 Figure 2 and Figure 5 shown, a driving mechanism 4 is installed inside the base 1 and is matched with the adjustable loading mechanism 2 and the feeding mechanism 3. The driving mechanism 4 includes sliding grooves 41 symmetrically opened on both sides of the upper surface of the base 1. A bidirectional lead screw 42 is rotatably connected through the inside of the sliding groove 41. Two sliders 43 that are slidably connected to the inner wall of the sliding groove 41 are symmetrically threadedly connected to the outer surface of the bidirectional lead screw 42. The tops of the sliders 43 are respectively fixedly connected to the bottoms of the corresponding first side plate 21 and the support plate 31. A driving motor 44 is fixedly connected to one side of the outer surface of the base 1. The output shaft of the driving motor 44 is fixedly connected to one end of the adjacent bidirectional lead screw 42. Belt pulleys 45 are fixedly connected to one ends of the two bidirectional lead screws 42. A synchronous belt 46 is meshed and connected between the two belt pulleys 45. Two dovetail blocks 47 are symmetrically and fixedly connected to the bottoms of the first side plate 21 and the support plate 31. A dovetail groove 48 that is slidably connected to the dovetail blocks 47 is opened on the upper surface of the base 1.

[0032] The driving motor 44 rotates to drive the corresponding bidirectional lead screw 42 to rotate. Under the action of the belt pulleys 45 and the synchronous belt 46, the two bidirectional lead screws 42 can be driven to rotate simultaneously, and then the two sliders 43 on one side can be driven to move relatively, so that the widths of the adjustable loading mechanism 2 and the feeding mechanism 3 can be adjusted, enabling them to convey bar stocks of different lengths, improving practicability, and thus solving the problem that the structure of the existing device is fixed and cannot be adjusted according to bar stocks of different lengths.

[0033] Working principle: When loading materials, the bar stock can be directly placed on the two inclined loading plates 25 of the adjustable loading mechanism 2, and then the vibration motor 26 is started. With the cooperation of the spring 23, the bar stock can automatically move along the inclined loading plate 25 without the need to lift and stack the bar stock, reducing the work burden, thus solving the problem that the existing device needs to lift and stack the bar stock in the material rack and increases the work burden. And during the movement of the bar stock, the clamping cylinder 27 can drive the clamping plate 28 to clamp the bar stock, so that the bar stock can fall one by one, avoiding affecting the feeding mechanism 3.

[0034] The bar stock on the adjustable loading mechanism 2 will automatically fall onto the conveyor belt 34 of the feeding mechanism 3. The second side plate 32 and the partition 35 can continuously limit and convey the bar stock, which can not only improve work efficiency but also prevent the bar stock from falling, thus solving the problem that the existing device can only load one piece of material at a time and reduces work efficiency.

[0035] The driving motor 44 rotates to drive the corresponding bidirectional lead screw 42 to rotate. Under the action of the belt pulley 45 and the synchronous belt 46, two bidirectional lead screws 42 can be driven to rotate simultaneously. Furthermore, two sliders 43 on one side can be driven to move relatively, so that the widths of the adjustable loading mechanism 2 and the feeding mechanism 3 can be adjusted, enabling them to convey bar stocks of different lengths, improving practicability, and thus solving the problem that the structure of the existing device is fixed and cannot be adjusted according to bar stocks of different lengths.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

This narrative way of the specification is only for clarity.
