[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4An embodiment of this utility model provides a carbon brush pressing and molding machine, including a molding table 1. A rectangular mounting groove 101 is provided in the middle of the upper end face of the molding table 1. A rectangular movable groove 102 is provided inside the molding table 1 in the middle of the lower end of the rectangular mounting groove 101. A molding mold 2 is fixedly connected inside the rectangular mounting groove 101. A rectangular pressing cavity 201 is provided in the middle of the molding mold 2. A support plate 105 is provided at the lower end of the rectangular movable groove 102. An ejector core 3 is fixedly connected to the middle of the upper end of the support plate 105. A mounting seat 6 is fixedly connected to the middle of the rear end of the rectangular mounting groove 101 on the upper end face of the molding table 1. The rear end of the mounting seat 6 is fixed. An electrically controlled telescopic rod 601 is connected. The front end of the telescopic end of the electrically controlled telescopic rod 601 extends out of the front end of the mounting base 6 and is fixedly connected to a rubber push plate 602. A trapezoidal guide groove 103 is provided on the upper surface of the molding table 1 at the middle of the front end of the rectangular mounting groove 101. An ejector cylinder 104 is fixedly connected inside the molding table 1 at the middle of the lower end of the rectangular movable groove 102. The upper end of the telescopic end of the ejector cylinder 104 extends into the interior of the rectangular movable groove 102 and is fixedly connected to the middle of the lower end of the support plate 105. The upper and lower ends of the rectangular pressing cavity 201 are connected to the upper and lower end faces of the molding mold 2, respectively. The upper end of the ejector core 3 is inserted into the lower end of the rectangular pressing cavity 201.

[0020] After the carbon brush is pressed and formed inside the rectangular pressing cavity 201, the support plate 105 is raised by the ejector cylinder 104, which in turn raises the ejector core 3 to eject the pressed carbon brush from the upper surface of the forming mold 2 along the rectangular pressing cavity 201. Then, the rubber push plate 602 is moved forward by the electric telescopic rod 601 to push the ejected carbon brush forward into the trapezoidal guide groove 103. An additional conveyor belt mechanism can be set at the front end of the forming table 1 so that the carbon brush falling into the trapezoidal guide groove 103 slides through the trapezoidal guide groove 103 and enters the conveyor belt for continuous conveying.

[0021] Please see Figure 2 and Figure 3 A C-shaped support frame 4 is fixedly connected to the upper middle part of the forming table 1. A lifting plate 5 is connected to the upper middle part of the inner side of the C-shaped support frame 4. A pressing mold core 501 is fixedly connected to the lower middle part of the lifting plate 5. A hydraulic cylinder 402 is fixedly connected to the middle part of the upper surface of the C-shaped support frame 4. The lower end of the telescopic end of the hydraulic cylinder 402 passes through the C-shaped support frame 4 and is fixedly connected to the upper middle part of the lifting plate 5.

[0022] After the raw material is injected into the rectangular pressing cavity 201, the hydraulic cylinder 402 drives the lifting plate 5 to descend, so that the lifting plate 5 drives the pressing mold core 501 to be inserted into the rectangular pressing cavity 201 to press and shape the raw material. After pressing is completed, the lifting plate 5 is raised and drives the pressing mold core 501 to leave the rectangular pressing cavity 201.

[0023] Please see Figure 2 and Figure 3The upper middle of both ends of the C-shaped support frame 4 is fixedly connected to guide tubes 401, and the upper ends of the lifting plate 5 are fixedly connected to guide rods 502. The upper ends of the two guide rods 502 pass through the interior of the two guide tubes 401 and extend out of the upper end of the C-shaped support frame 4.

[0024] When the lifting plate 5 is raised or lowered, it is guided by the guide rod 502 sliding inside the guide tube 401 to ensure the stability of the lifting plate 5 during the raising and lowering process.

[0025] Please see Figure 2 and Figure 4 An inclined feeding channel 202 is provided inside the molding die 2 and in the middle of one side of the rectangular pressing cavity 201. The lower end of the inclined feeding channel 202 is connected to the upper side of the rectangular pressing cavity 201. The upper end of the inclined feeding channel 202 is connected to the upper surface of the molding die 2 and a threaded connecting pipe 203 is fixedly connected to the upper end of the connection position. A storage tank 403 is fixedly connected to one side of the middle of the upper end of the C-shaped support frame 4. The lower end of the storage tank 403 extends to the inside of the C-shaped support frame 4 and is fixedly connected to a powder metering pump 404. A soft guide pipe 405 is fixedly connected to the lower end of the powder metering pump 404. The lower end of the soft guide pipe 405 is threadedly connected to the threaded connecting pipe 203.

[0026] The raw material inside the storage tank 403 is quantitatively conveyed to the inclined feeding channel 202 through the soft guide pipe 405 by the powder metering pump 404. The raw material is then injected into the rectangular pressing cavity 201 through the inclined feeding channel 202. By controlling the amount of raw material conveyed, the upper end of the raw material entering the rectangular pressing cavity 201 is lower than the lower end of the connection between the inclined feeding channel 202 and the rectangular pressing cavity 201, so as to prevent the raw material from overflowing into the inclined feeding channel 202 when the pressing mold core 501 enters the rectangular pressing cavity 201 to press the raw material.

[0027] Working Principle: In operation, the carbon brush raw material in the storage tank 403 is first quantitatively injected into the rectangular pressing cavity 201 of the molding die 2 via the powder metering pump 404 through the soft guide pipe 405 and the inclined feeding channel 202. Then, the hydraulic cylinder 402 pushes the lifting plate 5 downwards, causing the pressing die core 501 to insert into the rectangular pressing cavity 201, pressing the raw material. During pressing, the lower end of the raw material is supported by the upper end of the ejector die core 3. After molding, the hydraulic cylinder 402 drives the lifting plate 5 and the pressing die core 501 upwards to reset. Next, the ejector cylinder 104 pushes the support plate 105 and the ejector die core 3 upwards, ejecting the molded carbon brush from the rectangular pressing cavity 201. Afterwards, the electrically controlled telescopic rod 601 pushes the rubber push plate 602 forward, pushing the ejected carbon brush into the trapezoidal guide groove 103. The carbon brush slides down the guide groove to the external conveying equipment, achieving automatic discharge and continuous production.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
