Technical Field

[0001] This utility model relates to the field of silicon molybdenum products technology, specifically to an automatic feeding device for pressing and molding silicon molybdenum product raw materials. Background Technology

[0002] Molybdenum disilicide products are high-temperature resistant and oxidation-resistant resistance heating elements made from molybdenum disilicide. They possess unique high-temperature oxidation resistance, allowing them to be used in high-temperature oxidizing atmospheres. A bright and dense quartz glass film forms on the surface, protecting the inner layer from further oxidation. During the production process, to shape the raw material into a specific form for subsequent firing, a pressing and molding device is used to press the raw material powder into shape. In the existing technology, [the following is a separate section, likely related to a patent publication number (CN)]... Patent 220278261U discloses a molybdenum product raw material pressing and molding device, including a base and a die-casting molding shell. The die-casting molding shell is fixedly connected to the top of the base. A die-casting mechanism is provided in the middle of the top of the die-casting molding shell.

A feeding electric push rod for driving the feeding mechanism to move left and right is provided at one end of the base. One end of the feeding electric push rod is fixedly connected to one end of the feeding mechanism. An ejection mechanism is fixedly connected to the bottom of the base. During the feeding process, the raw material falls directly into the molding cavity. The distribution of the raw material inside the molding cavity is not compact enough, which can easily lead to deviations in the amount of raw material fed. Utility Model Content

During the feeding process, the device continuously presses the silicon molybdenum product raw materials, which can make the filling of the silicon molybdenum product raw materials in the pressing and molding cavity more compact, ensuring the accuracy and uniformity of feeding, and effectively solving the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding device for pressing and molding silicon molybdenum products, including a worktable, a chute on the upper surface of the worktable, a lower pressure plate in the mounting groove in the middle of the bottom wall of the chute, a movable upper pressure plate on the upper end of the gantry frame on the upper surface of the worktable, and a feeding mechanism.

A pressure plate is vertically slidably connected inside the gate-shaped partition shell. During the feeding process of pushing the silicon molybdenum product raw material, the silicon molybdenum product raw material is continuously pressed.

[0006] Furthermore, the feeding mechanism also includes a cylinder, a spring, and a frame plate. The frame plate is vertically slidably connected to the inside of the gate-shaped partition shell. The lower surface of the frame plate is provided with a cylinder. The sliding columns on the upper surface of the pressure plate are vertically slidably connected to the inside of the cylinder. Springs are provided between the upper surface of the pressure plate sliding columns and the top wall of the cylinder, so that the pressure plate can elastically press the raw material and avoid excessive pressure.

[0007] Furthermore, the feeding mechanism also includes a turntable and a rotating column. The turntable is rotatably connected to the upper end of the front and rear inner walls of the feeding shell via a rotating shaft. A rotating column is provided between the eccentric ends of the two turntables. The rotating column is laterally slidably connected to the inside of the frame plate, driving the pressure plate to move up and down reciprocally.

[0008] Furthermore, the ends of the rotating shafts of the turntable extend through the interior of the feed shell and are equipped with gears. The upper ends of the front and rear inner walls of the slide are equipped with rack plates.

[0010] Furthermore, the upper surface of the gate-shaped partition shell is provided with an arc-shaped plate, and the surface material is deposited on the upper surface of the gate-shaped partition shell.

[0011] Furthermore, there is a gap between the rubber pad and the bottom wall of the chute, and the lower surface of the upper shell is in contact with the bottom wall of the chute.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: an automatic feeding device for pressing and molding silicon molybdenum product raw materials, including a worktable 1, which provides support for the setting of silicon molybdenum product raw material pressing and molding components. The upper surface of the worktable 1 is provided with a sliding groove 2, which provides space for the setting of the pressing and molding components. A lower pressure plate 3 is provided in the mounting groove in the middle of the bottom wall of the sliding groove 2. A movable upper pressure plate 4 is provided at the upper end of the portal frame on the upper surface of the worktable 1. The silicon molybdenum product raw material is fed into the molding cavity of the lower pressure plate 3. After the feeding is completed, the upper pressure plate 4 is pushed down by the electric push rod on the portal frame of the worktable 1. Through the cooperation of the upper pressure plate 4 and the lower pressure plate 3, the silicon molybdenum product raw material is pressed and molded. The device also includes a feeding mechanism 5.

[0021] The feeding mechanism 5 includes a feeding shell 51, a gate-shaped partition shell 52, a rubber pad 53, and a pressure plate 54. The feeding shell 51 is laterally slidably connected to the inside of the slide groove 2. Slider blocks are provided on both the front and rear sides of the feeding shell 51. The sliders are laterally slidably connected to the rotating grooves on the front and rear inner walls of the slide groove 2. Each slider has a screw hole in its center. The upper and lower surfaces of the feeding shell 51 are open structures. A gate-shaped partition shell 52 is provided between the front and rear inner walls of the feeding shell 51. A rubber pad 53 is provided on the lower surface of the gate-shaped partition shell 52. The pressure plate 54 is vertically slidably connected inside the gate-shaped partition shell 52. Silicon molybdenum product raw materials are poured into the feeding shell 51. Through the reciprocating left and right movement of the feeding shell 51, the silicon molybdenum product raw materials fall from the opening at the lower end of the feeding shell 51 into the forming cavity of the lower pressure plate 3. After the lower pressure plate 3 is filled into the molding cavity, the silicon molybdenum product raw material cannot leave the upper shell 51. As the upper shell 51 continues to move, the pressure plate 54 moves up and down reciprocally. When the pressure plate 54 moves down and contacts the rubber pad 53, the pressure plate 54 pushes the rubber pad 53 to deform, pressing the silicon molybdenum product raw material on the lower surface of the rubber pad 53. The raw material inside the upper shell 51 transmits the force to the raw material inside the molding cavity, making the raw material inside the molding cavity more compact and ensuring the accuracy of feeding. The feeding mechanism 5 also includes a cylinder 55, a spring 56, and a frame plate 59. The frame plate 59 is vertically slidably connected to the inside of the door-shaped partition shell 52. The lower surface of the frame plate 59 is provided with cylinders 55. The sliding columns on the upper surface of the pressure plate 54 are vertically slidably connected to the cylinders 55. Inside the cylinder 55, springs 56 are provided between the upper surface of the sliding column of the pressure plate 54 and the top wall of the cylinder 55. The feeding mechanism 5 also includes a turntable 57 and a rotating column 58. The turntable 57 is rotatably connected to the upper ends of the front and rear inner walls of the feeding shell 51 via rotating shafts. A rotating column 58 is provided between the eccentric ends of the two turntables 57. The rotating column 58 is laterally slidably connected to the inside of the frame plate 59. The ends of the rotating shafts of the turntables 57 extend out of the inside of the feeding shell 51 and are provided with gears 6. The upper ends of the front and rear inner walls of the slide groove 2 are provided with rack plates 7. The gears 6 mesh with the adjacent rack plates 7. During the movement of the feeding shell 51, the gears 6 and rack plates 7 rotate relative to each other, driving the turntable 57 and rotating column 58 to rotate, so that the frame plate 59 drives the cylinder 55 to move up and down reciprocally inside the portal-shaped partition shell 52. When the pressure plate 54 moves down and contacts the rubber pad 53, the pressure from the silicon molybdenum product material overcomes the elastic force of the spring 56, causing the cylinder 55 and the sliding column of the pressure plate 54 to slide relative to each other. Under the elastic force of the spring 56, the pressure plate 54 pushes the rubber pad 53 to deform, avoiding excessive pressure on the silicon molybdenum product material. Reciprocating screws 8 are rotatably connected to the rotating grooves on the front and rear inner walls of the slide groove 2. The reciprocating screws 8 are threadedly connected to the screw holes of the upper material shell 51. A worm gear 9 is provided at the left end of each reciprocating screw 8. A worm 10 is rotatably connected between the front and rear inner walls of the drive groove on the left end of the worktable 1. The worm gear 9 is meshed with the worm 10. A drive motor 11 is provided on the front surface of the worktable 1. The output shaft of the drive motor 11 is fixedly connected to the worm 10. The drive motor 11 is started.The output shaft of the drive motor 11 drives the worm gear 10 to rotate. Through the meshing connection between the worm gear 10 and the worm wheel 9, the worm wheel 9 drives the two reciprocating screws 8 to rotate synchronously. Through the threaded connection between the reciprocating screws 8 and the loading shell 51, the loading shell 51 is driven to move back and forth in the slide groove 2. A microcontroller 12 is provided on the left side of the workbench 1 to control the start and stop of the entire device. The input terminal of the microcontroller 12 is electrically connected to an external power supply, and the input terminal of the drive motor 11 is electrically connected to the output terminal of the microcontroller 12. The upper surface of the door-shaped partition shell 52 is provided with an arc plate 13 to prevent the raw materials of silicon molybdenum products from being inside the door. The upper surface of the partition shell 52 is filled with material, and there is a gap between the rubber pad 53 and the bottom wall of the slide 2, allowing the space between the rubber pad 53 and the bottom wall of the slide 2 to be filled with silicon molybdenum product material. This silicon molybdenum product material is used to transmit force, facilitating the application of force to the material inside the molding cavity. The lower surface of the upper shell 51 is in contact with the bottom wall of the slide 2. During the movement of the upper shell 51, it pushes and scrapes against the bottom wall of the slide 2, preventing the silicon molybdenum product material from remaining on the bottom wall of the slide 2. This ensures that the silicon molybdenum product material can only fall from the opening at the lower end of the upper shell 51 into the molding cavity of the lower pressure plate 3.

[0022] The working principle of the automatic feeding silicon molybdenum product raw material pressing and molding device provided by this utility model is as follows: During use, the silicon molybdenum product raw material is poured into the feeding shell 51. The microcontroller 12 starts the drive motor 11, and the output shaft of the drive motor 11 drives the worm gear 10 to rotate. Through the meshing connection between the worm gear 10 and the worm wheel 9, the worm wheel 9 drives two reciprocating screws 8 to rotate synchronously. Through the threaded connection between the reciprocating screws 8 and the feeding shell 51, the feeding shell 51 moves back and forth in the slide 2. During the movement, the lower surface of the feeding shell 51 is in contact with the bottom wall of the slide 2, using the feeding shell 51 to push and scrape the bottom wall of the slide 2, preventing the silicon molybdenum product raw material from remaining on the bottom wall of the slide 2. The silicon molybdenum product raw material can only fall from the opening at the lower end of the feeding shell 51 into the molding cavity of the lower pressure plate 3. At the same time, the gear 6 and the rack plate 7 rotate relative to each other, driving the turntable 57 and the rotating column 58 to rotate, causing the frame plate 59 to move... The moving cylinder 55 moves up and down inside the portal frame 52. After the silicon molybdenum product raw material fills the molding cavity of the lower pressure plate 3, the silicon molybdenum product raw material can no longer leave the upper shell 51. As the cylinder 55 moves up and down, when the pressure plate 54 moves down and contacts the rubber pad 53, the pressure of the silicon molybdenum product raw material overcomes the elastic force of the spring 56, causing the cylinder 55 and the sliding column of the pressure plate 54 to slide relative to each other. Under the elastic force of the spring 56, the pressure plate 54 pushes the rubber pad 53 to deform, pressing the silicon molybdenum product raw material on the lower surface of the rubber pad 53. The material inside the upper shell 51 transmits the force to the material inside the molding cavity, making the material inside the molding cavity more compact and ensuring the accuracy of feeding. After feeding is completed, the electric push rod on the portal frame of the worktable 1 pushes the upper pressure plate 4 down. Through the cooperation of the upper pressure plate 4 and the lower pressure plate 3, the silicon molybdenum product raw material is pressed into shape.

[0023] It is worth noting that the microcontroller 12 disclosed in the above embodiments can be an AT89C4051 microcontroller, and the drive motor 11 can be freely configured according to the actual application scenario. It is recommended to use an HC-KFS servo motor. The microcontroller 12 controls the drive motor 11 using methods commonly used in the prior art.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
