DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0039] It should be noted that the control terminal 8 is a controller for controlling the start, stop and operation of the equipment. This structure has been widely used in the prior art. In the present invention, it is only used to realize the functions of controlling the die-casting structure 3, the feeding device 4 and the discharge conveyor belt 7, and is used to perform the die-casting action of the die-casting structure 3, the feeding device 4 replenishing the magnetic raw materials for the material filling structure 5 and the operation of the discharge conveyor belt 7;

[0040] Similarly, the above-mentioned discharge conveyor belt 7 is a conventional conveyor belt in the prior art, which is used to convey materials to the next process. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of conveying the magnetic components completed by die-casting;

[0041] The implementation methods of the above two structures are both conventional technical means in the prior art. In the present invention, the specific internal structure, operating principle, wiring, and control method of the above-mentioned discharge conveyor belt 7 and control terminal 8 are no longer described in detail.

[0042] During the operation of this embodiment, the die discharge structure 6 is first filled with magnetic material by utilizing the cooperation of the die-casting structure 3 and the material filling structure 5, and then the magnetic material in the die discharge structure 6 is die-cast by utilizing the action of the die-casting structure 3. During the die-casting ascending process of the die-casting structure 3, the die discharge structure 6 is driven to move by utilizing the cooperation of the die-casting structure 3 and the die discharge structure 6, and the die-cast magnetic element is pushed out by the action of the die discharge structure 6. The material filling structure 5 is driven to move forward by utilizing the cooperation of the die-casting structure 3 and the material filling structure 5, thereby pushing the magnetic element that has escaped from the die discharge structure 6 forward, and finally enters the discharge conveyor belt 7 through the guide slope 2 for delivery. At the same time, the material filling structure 5 replenishes the die discharge structure 6, and completes automatic loading, demolding, and discharging, thereby simplifying the production process and improving product production efficiency and quality. Embodiment 2

[0043] On the basis of the first embodiment, the present embodiment drives the sliding plate 32 to slide up and down in the U-shaped support frame 31 through the hydraulic cylinder 33, and utilizes the interaction between the die-casting rod 35 and the supporting member 63 and the bottom supporting member 64 to pressurize the magnetic material on the upper part of the bottom supporting member 64 to form it, and drives the discharge member 65 to operate through the interaction between the linkage member 34 and the cross pulley 61 and the straight connecting rod 62 to lift the bottom supporting member 64, thereby pushing the die-cast magnetic material out of the die-casting hole 632, thereby realizing automatic discharge, simplifying the demoulding process, and improving production efficiency.

[0044] Specifically, to realize the die-casting of magnetic materials, refer to Figure 3 and Figure 4The die-casting structure 3 includes a U-shaped support frame 31 fixedly connected to the upper end of the machine table 1, a hydraulic cylinder 33 is fixedly connected to the upper end of the horizontal part of the U-shaped support frame 31, and a sliding plate 32 slidably connected to the inner surfaces of the vertical parts on both sides of the U-shaped support frame 31 is fixedly connected to the output end of the hydraulic cylinder 33, and a plurality of die-casting rods 35 are linearly distributed and fixedly connected to the lower end of the sliding plate 32, and a linkage member 34 slidably connected to the inner surface of the vertical part of the U-shaped support frame 31 on the same side is symmetrically fixedly connected to the lower end of the sliding plate 32, and an L-shaped guide groove 36 connected to the outer surface of the vertical part of the U-shaped support frame 31 is provided on the inner surface, and the inner surfaces of the two L-shaped guide grooves 36 are slidably connected to the die discharge structure 6, and a guide rail 37 is fixedly connected to the lower part of the side where the vertical parts of the U-shaped support frame 31 are close to each other.

[0045] The U-shaped support frame 31 is used to provide installation support for the hydraulic cylinder 33 and limit the running trajectory of the sliding plate 32 so that it can only move up and down in the vertical direction. At the same time, the L-shaped guide groove 36 opened in the vertical part of the U-shaped support frame 31 is used to cooperate with the linkage 34 and the die discharge structure 6 to demold the molded parts, and the guide rail 37 is used to limit the running trajectory of the material filling structure 5.

[0046] It should be noted that the hydraulic cylinder 33 is a conventional hydraulic device, which extends and retracts the piston rod through the action of a hydraulic press, and its operating state is controlled by a control terminal 8. This structure has been widely used in the prior art. In the present invention, it is only used to realize the function of telescoping and driving the sliding plate 32 to move up and down, and its internal structure, operating principle, circuit, oil circuit and control method are not described in detail.

[0047] Further, in order to realize the driving of the material filling structure 5 and the die discharge structure 6, refer to Figure 5 , Figure 6 and Figure 7 The linkage member 34 includes a mounting plate 341 fixedly connected to the lower end of the sliding plate 32, a buffer groove 344 is provided on the side of the mounting plate 341 close to the sliding plate 32, a buffer spring 346 is fixedly connected to the top wall of the inner surface of the buffer groove 344, the lower end of the buffer spring 346 is fixedly connected to a slider 345 slidingly connected to the inner surface of the buffer groove 344, the end of the slider 345 close to the sliding plate 32 is rotatably connected to an L-shaped connecting rod 343 rotatably connected to the material filling structure 5, and the lower end of the mounting plate 341 is fixedly connected to an L-shaped hook tongue 342.

[0048] It should be noted that the slider 345 slides up and down in the mounting plate 341. When the sliding plate 32 is at the uppermost position, the buffer spring 346 is in a released state, and the slider 345 is at the lower part of the buffer slot 344. When the sliding plate 32 is at the lowermost position, the buffer spring 346 is compressed by force to make the upper end of the slider 345 fit with the lower end of the sliding plate 32.

[0049] When the sliding plate 32 moves from top to bottom, the buffer spring 346 will first press the slider 345 to move down synchronously with the sliding plate 32. At this time, the material filling structure 5 moves backward along the guide rail 37 under the action of the L-shaped connecting rod 343 until the material filling structure 5 completely passes over the die discharge structure 6 and returns to the upper rear of the machine table 1. At this time, the material filling structure 5 reaches the rearmost part, and the slider 345 cannot continue to descend. The buffer spring 346 is compressed until the sliding plate 32 reaches the maximum stroke. At this time, the slider 345 is tightly attached to the lower end of the sliding plate 32, and the L-shaped hook tongue 342 is engaged with the cross pulley 61.

[0050] When the sliding plate 32 completes the die-casting and rises, the sliding plate 32 rises and drives the cross pulley 61 to rise through the L-shaped hook tongue 342. At this time, under the action of the buffer spring 346, the slider 345 will stay at the original height until the die discharge structure 6 ejects the die-cast material. The slider 345 fits with the lower end of the buffer chute 344 and is driven to rise by the mounting plate 341. At this time, the slider 345 drives the L-shaped connecting rod 343 to move, and drives the material filling structure 5 to slide forward in the guide rail 37 through the L-shaped connecting rod 343, pushing the magnetic element ejected by the die discharge structure 6 onto the guide slope 2 and sending it out via the discharge conveyor belt 7. At the same time, the cross pulley 61 is disengaged from the L-shaped hook tongue 342 through the action of the L-shaped guide groove 36. At this time, the die discharge structure 6 is reset and automatically replenished with material through the material filling structure 5.

[0051] Further, in order to follow the movement of the sliding plate 32 to drive the bottom support member 64 and the material discharging member 65 to move, refer to Figure 8 and Fig. 9 The die discharge structure 6 includes a cross pulley 61 slidably connected to the inner surface of the adjacent L-shaped guide groove 36, and the ends of the two cross pulleys 61 away from the sliding plate 32 are rotatably connected to a straight connecting rod 62. The lower ends of the two straight connecting rods 62 pass through the upper end of the machine table 1 and extend to the inner cavity of the machine table 1 and are rotatably connected to a discharge piece 65. The two discharge pieces 65 are fixedly connected to a supporting piece 63 in the middle of the upper end of the machine table 1, and the inner surface of the supporting piece 63 is provided with a bottom supporting piece 64 that is closely attached to the upper part of the discharge piece 65.

[0052] The bottom of the L-shaped hook tongue 342 is an arc surface and has a certain elasticity. When it contacts the cross pulley 61 from top to bottom, its arc surface part will guide the connecting rod between it and the sliding plate 32 to deform and pass over the cross pulley 61 to reach the bottom of the cross pulley 61. When the L-shaped hook tongue 342 rises, since its upper side is a plane, it will hook the cross pulley 61 and move upward along the L-shaped guide groove 36.

[0053] The cross pulley 61 slides in the L-shaped guide groove 36. When the L-shaped hook tongue 342 hooks the cross pulley 61 and moves upward with the sliding plate 32, it will drive the straight connecting rod 62 to rise, and thereby drive the discharge part 65 to drive the bottom support part 64 to rise, and eject the die-cast material. When the material filling structure 5 pushes the ejected material forward, the cross pulley 61 enters the curved area of ​​the L-shaped guide groove 36, and thereby disengages from the L-shaped hook tongue 342 and slides downward along the L-shaped guide groove 36 to reset, and then the material filling structure 5 is used to replenish the material.

[0054] In addition to allowing the straight-connecting rod 62 to slide up and down, the sliding groove between the straight-connecting rod 62 and the machine table 1 can also allow the straight-connecting rod 62 to swing to a certain extent in the front-to-back direction to adapt to the front-to-back position change of the cross pulley 61 when moving in the L-shaped guide groove 36. This limiting method is a conventional technical means and its detailed structure is not shown in the present invention.

[0055] Further, for providing molds for die casting and cleaning residues, refer to Fig.10 The supporting member 63 includes a straight plate 631 fixedly connected to the machine table 1 and horizontal to the upper end of the machine table 1, a plurality of die-casting holes 632 are opened at the upper end of the straight plate 631, and a bottom supporting member 64 is arranged on the inner surfaces of the plurality of die-casting holes 632, a fence plate 633 is opened at the front part of the upper end of the straight plate 631, and a slag box 634 is slidably connected to the inner surface of the straight plate 631 located below the fence plate 633.

[0056] The die-casting hole 632 opened on the straight plate 631 is used to cooperate with the die-casting rod 35 to die-cast the magnetic material. The cylindrical area formed by the top of the bottom support 64 in the die-casting hole 632, the inner wall of the die-casting hole 632 and the lower end of the die-casting rod 35 die-casts the magnetic material into a cylindrical magnet element.

[0057] When the material filling structure 5 pushes the magnetic part forward under the action of the linkage part 34, it will pass through the fence plate 633. At this time, the slag on the upper side of the straight plate 631 will be synchronously pushed into the slag box 634 through the fence plate 633, and the magnetic element will fall on the discharge conveyor belt 7 through the guide slope 2 and be sent out.

[0058] Further, in order to realize the bearing of the magnetic material and cooperate with the discharge member 65 to realize the removal and reset, refer to Fig.11 The bottom support member 64 includes a fixed column 643 fixedly connected to the lower end of the straight plate 631, the inner surface of the fixed column 643 is slidably connected to the receiving column 642 through a limiting rod, the upper end of the receiving column 642 is fixedly installed with a die-casting support 641 slidably connected to the inner surface of the die-casting hole 632, the lower end of the straight plate 631 is fixedly connected to a compression spring 644 fixedly connected to the upper end of the limiting rod arranged on the outer surface of the receiving column 642, the lower end of the receiving column 642 is a spherical surface and is tightly attached to the upper part of the discharge piece 65.

[0059] The die-casting support 641 installed on the receiving column 642 is used to cooperate with the die-casting hole 632 to receive the raw materials of the magnetic material. At the same time, the fixed column 643 located below the straight plate 631 limits the stroke of the die-casting support 641. When the die-casting rod 35 is pressed down, it is used to cooperate with the die-casting rod 35 to die-cast the magnetic material therein. After the die-casting is completed, the die-casting support 641 cooperates with the discharge piece 65 to move upward to push the material out of the die-casting hole 632, and after the cross pulley 61 is disengaged from the L-shaped hook tongue 342 to reset the discharge piece 65, it is reset by the compression spring 2 644, and cooperates with the material filling structure 5 to replenish the material.

[0060] Further, in order to realize the pushing of the bottom support member 64 so that the die-cast material can be removed, refer to Fig.11 The discharging member 65 includes connecting rods 654 that are symmetrically distributed on the left and right and are rotatably connected to the lower ends of adjacent straight connecting rods 62 through universal joints. The ends of the two connecting rods 654 that are away from the straight connecting rods 62 are rotatably connected to a slide plate 651 that is slidably connected to the bottom wall of the inner cavity of the machine 1. The bottom wall of the inner cavity of the machine 1 is provided with a mounting groove at a position below the slide plate 651. The end of the mounting groove that is close to the connecting rod 654 on the same side is fixedly connected to a return spring 652 that is fixedly connected to the lower end of the slide plate 651. The sides of the two slide plates 651 that are close to each other are rotatably connected to connecting rods 655. The ends of the two connecting rods 655 that are away from the slide plate 651 are rotatably connected to slide plate 656. The upper ends of slide plates 656 and slide plate 651 are fixedly connected to a wedge block 653 that is tightly attached to the lower end of the receiving column 642.

[0061] The rotational connection through the universal joint can allow the straight-link rod 62 and the connecting rod 654 to have an angular offset, but this angular offset will not affect the position change of the straight-link rod 62 and the connecting rod 654 in the vertical direction. When the cross pulley 61 is in the curved area of ​​the L-shaped guide groove 36 so that the angle of the straight-link rod 62 and the connecting rod 654 changes, the universal joint can provide a buffer for the angle change.

[0062] When the straight connecting rod 62 follows the rising process of the cross pulley 61, it will drive the connecting rod 1 654 to rise along with the movement of the straight connecting rod 62, thereby pulling the slide plate 1 651 to slide in the direction of the connecting rod 1 654 on the same side. At the same time, the slide plate 2 656 is driven to slide forward through the connecting rod 2 655, so that the wedge block 653 pushes the die-casting support 641 to rise under the limit of the fixed column 643 and push the die-cast material out of the die-casting hole 632 until the cross pulley 61 is detached from the L-shaped hook tongue 342. Under the action of the reset spring 652, the slide plates 1 651 and 2 656 are reset. At this time, the die-casting support 641 is reset under the action of the compression spring 2 644. Embodiment 3

[0063] On the basis of the second embodiment, this embodiment further drives the roller 54 to slide in the guide rail 37 through the action of the slider 345, the buffer spring 346 and the L-shaped connecting rod 343, thereby driving the storage box 51 to slide on the upper part of the machine table 1, and the rubber shovel 56 cooperates with the bottom support member 64 and the discharge member 65 to push the material pushed out by the bottom support member 64 into the guide slope 2, so as to realize automatic unloading, and synchronously use the action of the discharge port 53 to replenish the die-casting hole 632 and the bottom support member 64 after reset.

[0064] Further, to achieve automatic feeding, see Fig.12 and Fig.13 The material filling structure 5 includes a storage box 51, which is connected to the feeding device 4 through a feeding pipe. An auxiliary filling piece 52 is provided at the front of the inner surface of the storage box 51, and a discharge port 53 connected to the lower end is provided at the rear of the inner surface of the auxiliary filling piece 52. The left and right ends of the storage box 51 are rotatably connected to rollers 54 rotatably connected to the L-shaped connecting rod 343 on the same side. The outer surface of the roller 54 is slidably connected to the inner surface of the guide rail 37. The bottom wall of the inner surface of the guide rail 37 is provided with a plurality of tooth openings 55. The lower front end of the storage box 51 is fixedly connected to a rubber shovel 56 that is tightly attached to the machine table 1 and the upper end of the die discharge structure 6.

[0065] The material storage box 51 is connected to the feeding device 4, which will continuously provide raw materials to the material filling structure 5, and when the material storage box 51 moves forward through the action of the L-shaped connecting rod 343 and the roller 54, the rubber shovel 56 will first be used to push the magnetic elements and debris on the straight plate 631 onto the fixed column 643 and the guide slope 2, until the discharge port 53 moves above the die-casting hole 632 and allows the magnetic material powder in the material storage box 51 to fall into the die-casting hole 632, thereby completing the material filling. Embodiment 4

[0066] On the basis of the third embodiment, the present embodiment utilizes the cooperation between the gear 522 and the tooth mouth 55 to drive the cam 524 therein to rotate, and the rotation of the cam 524 periodically presses the T-shaped limit rod 525 downward to drive the magnet 1 527 to descend, and when the magnet 1 527 contacts the magnet 2 528, they are adsorbed together and thereby pull the impact hammer 520 upward, until the suction force of the magnet 2 528 and the magnet 1 527 is insufficient to resist the elastic potential energy of the tension spring 529, and the magnet 2 528 is released and causes the impact hammer 520 to impact the bottom wall of the mounting shell 521, thereby compacting the magnetic material powder filled in the die-casting hole 632, reducing the gaps and holes therein, and thereby improving the die-casting quality.

[0067] Specifically, in order to compact the magnetic powder in the die-casting hole 632 and reduce the gap therein, refer to Fig.13The auxiliary filler member 52 includes a gear 522 meshing with the tooth openings 55 in the guide rails 37 on both sides and a mounting shell 521. The gears 522 on both sides are fixedly connected to a plurality of staggered cams 524 through a transmission shaft. An isolation plate 523 is fixedly connected to the middle of the inner surface of the mounting shell 521. A plurality of compression springs 526 are linearly fixedly connected to the upper end of the isolation plate 523. The upper ends of the plurality of compression springs 526 are fixedly connected to T-shaped limit rods 525 that penetrate the upper end of the isolation plate 523 and extend to the lower end of the isolation plate 523. The lower ends of the plurality of T-shaped limit rods 525 are fixedly connected to magnets 527 that are in close contact with the lower end of the isolation plate 523.

[0068] See also Fig.13 The auxiliary filling member 52 also includes a plurality of tension springs 529 fixedly connected to the bottom wall of the inner cavity of the linear distribution mounting shell 521, the upper ends of the plurality of tension springs 529 are fixedly connected to magnet 2 528, the lower ends of the plurality of magnet 2 528 are fixedly connected to impact hammer 520, and the upper end of magnet 2 528 has opposite polarity to the lower end of magnet 1 527.

[0069] When the material storage box 51 moves along the guide rail 37, the gear 522 will rotate under the action of the roller 54. At this time, the cam 524 will periodically press the T-shaped limit rod 525 to move downward. At this time, the compression spring 1 526 is compressed, and the magnet 1 527 moves downward and contacts with the magnet 2 528. Since the two have opposite polarities, they will be adsorbed together, and the magnet 2 528 will rise together with the magnet 1 527 due to the suction force. However, the suction force of the magnet 1 527 and the magnet 2 528 is very small. Under the action of the tension spring 529, they will separate at a certain height and under the action of the tension spring 529, the impact hammer 520 will drop rapidly and hit the bottom wall of the mounting shell 521. The bottom wall of the mounting shell 521 is very thin, and can transmit this impact to the upper end of the straight plate 631, compacting the powder in the die-casting hole 632 and reducing the gap therein, thereby improving the die-casting quality and avoiding the influence of too many gaps on the die-casting effect.
