Abstract
Description
Technical Field
[0001] The utility model relates to the field of a low-expansion graphite asphalt coke raw material pressing and forming die, and more specifically, to a low-expansion graphite asphalt coke raw material pressing and forming die. Background Art
[0002] Pitch coke is a type of coke, a solid product obtained by high-temperature dry distillation of coal tar pitch or petroleum pitch. The structural characteristics of pitch coke enable it to play a skeletal supporting role in the preparation of low-expansion graphite. It has good electrical conductivity and chemical stability, and can improve the physical and chemical properties of low-expansion graphite to a certain extent. When mixed with other raw materials, pitch coke can improve the molding properties of graphite, making the final low-expansion graphite product have better strength and toughness. When pressing the pitch coke raw material, it is often necessary to use a pressing mold. The pressing mold can give the pitch coke a specific shape, such as pressing it into a plate, column or various complex geometric shapes to meet the requirements of subsequent processing and application of low-expansion graphite.
[0003] In the prior art, when pressing asphalt coke, the asphalt coke raw material is placed in a mold box and a pressing plate is used to apply pressure to the asphalt coke raw material to form the asphalt coke raw material in the mold cavity. Since the existing mold box and the pressing plate are usually separate, the pressing plate needs to be placed in the mold box for use during pressing. During the pressing process, in order to ensure that the asphalt coke raw material can be evenly compacted, the pressing plate needs to be accurately placed in the mold box. Since the mold box and the pressing plate are separate, the operator needs to manually align the pressing plate each time the pressing plate is placed. The thickness of the pressing plate is also small, and manual alignment is difficult. A slight deviation may lead to uneven pressure, affecting the quality of the molded product. Therefore, we propose a low-expansion graphite asphalt coke raw material pressing and molding mold to solve the above-mentioned problems. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the specification of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.
[0026] Example 1:
[0027] See also Figure 1-Figure 5 A low-expansion graphite pitch coke raw material pressing and molding die comprises a base 1 and a pressing plate 3. The surface of the base 1 is fixedly connected to a mold box 2. The surface of the mold box 2 is provided with a limiting structure 4. The limiting structure 4 comprises a support frame 401, which is fixedly connected to one side of the mold box 2. The surface of the support frame 401 is rotatably connected to a rotating shaft 402. The circular arc surface of the rotating shaft 402 is fixedly connected to a driving plate 403. A round rod 404 slides through the surface of the driving plate 403. The pressing plate 3 is fixedly connected to the end of the round rod 404 close to the mold box 2, and the end of the round rod 404 away from the pressing plate 3 is fixedly connected to a circular plate 405. The circular arc surface of the circular rod 404 is covered with a spring 406. The two ends of the spring 406 are respectively fixedly connected to the circular plate 405 and the driving plate 403. The surface of the driving plate 403 is slidably penetrated by a rectangular rod 407. The two ends of the rectangular rod 407 are respectively fixedly connected to the pressing plate 3 and the circular plate 405. A rubber protective pad 408 is fixedly attached to the surface of the pressure plate 3. A tapered groove 409 is formed on the surface of the circular plate 405. A rotating plate 410 is fixedly attached to one end of the rotating shaft 402. Several rotating rods 411 are fixedly attached to the arc surface of the rotating plate 410. A fixed rod 412 is fixedly attached to the inner wall of the support frame 401. A limit arm 413 is fixedly attached to the surface of the fixed rod 412. Rectangular plates 414 are fixedly attached to each end of the limit arm 413.
[0028] Working principle: When the asphalt coke raw material of low-expansion graphite needs to be pressed and formed, the rotating rod 411 is first rotated. The rotation of the rotating rod 411 will drive the rotating plate 410 to rotate. The rotation of the rotating plate 410 will drive the rotating shaft 402 to rotate in the support frame 401. The rotation of the rotating shaft 402 will drive the driving plate 403 to rotate. The rotation of the driving plate 403 will drive the round rod 404 to rotate. The rotation of the round rod 404 will drive the pressing plate 3 to rotate. The pressing plate 3 will move toward the direction close to the mold box 2. After the driving plate 403 rotates to a suitable angle, it will fit on the surface of the rectangular plate 414. The rectangular plate 414 reaches the limit of the rotation angle of the driving plate 403, thereby limiting the rotation angle of the pressing plate 3. When After the driving plate 403 is attached to the surface of the rectangular plate 414, the pressing plate 3 is located directly above the mold box 2 and perpendicular to the mold box 2. Then the base 1 is placed in the pressing machine, and the pressing head of the pressing machine slides into the conical groove 409 of the circular plate 405. The circular plate 405 is squeezed and presses the round rod 404. When the circular plate 405 moves, the spring 406 is compressed, and the round rod 404 moves and slides in the driving plate 403. The movement of the round rod 404 drives the pressing plate 3 to move in the direction close to the mold box 2. The movement of the pressing plate 3 drives the rectangular rod 407 to slide in the driving plate 403. The rectangular rod 407 reaches the limit of the moving cabinet path of the pressing plate 3, thereby preventing the pressing plate 3 from being deformed when moving. The function of rotation is that when the pressing plate 3 moves to the appropriate position, the pressing plate 3 will slide into the mold box 2, thereby pressing the asphalt coke raw material of low-expansion graphite in the mold box 2. After the asphalt coke raw material of low-expansion graphite is pressed and formed, the pressing machine is removed from the surface of the circular plate 405. The circular plate 405 will drive the round rod 404 to move with the help of the contraction force of the spring 406. The movement of the round rod 404 will drive the pressing plate 3 to gradually slide out of the mold box 2. After the pressing plate 3 moves to the appropriate position, it will drive the protective pad 408 to hit the surface of the driving plate 403. The spring 406 limits the position of the pressing plate 3, thereby facilitating the pressing plate 3 to slide out of the mold box 2, and the protective pad 408 can avoid The pressing plate 3 directly hits the surface of the driving plate 403, causing the driving plate 403 or the pressing plate 3 to deform, and then the rotating rod 411 is rotated in the opposite direction. The rotation of the rotating rod 411 will drive the rotating plate 410 to rotate, and the rotation of the rotating plate 410 will drive the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 will drive the driving plate 403 to rotate. The rotation of the driving plate 403 will drive the pressing plate 3 to rotate away from the top of the mold box 2 with the help of the round rod 404 until the driving plate 403 is attached to the surface of the rectangular plate 414, so as to facilitate the removal of the pressing plate 3 from the top of the mold box 2 for limited placement, and then facilitate the staff to take out the pressed low-expansion graphite pitch coke raw material from the mold box 2.
[0029] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
