DETAILED DESCRIPTION

[0031] The following describes the press cylinder forming assembly provided by the present invention in detail with reference to the accompanying drawings and specific embodiments. It is also noted that, in order to provide a more detailed description, the following embodiments are best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative implementations. Furthermore, the accompanying drawings are only provided to more specifically describe the embodiments and are not intended to limit the present invention.

[0032] like Figure 1 - Figure 10As shown, an embodiment of the present invention provides a pressing cylinder molding assembly, including a cylinder body, a pressing rod and a mold mounting cavity, and also includes: a carbon powder sealing device 2, arranged at the top of the mold mounting cavity, the carbon powder sealing device 2 includes: an outer layer 21, arranged at the top of the mold mounting cavity; an inner layer 22, arranged in the outer layer 21; a plurality of placement grooves 3, arranged on the outer layer 21, distributed in a circular pattern; a plurality of heating modules 4, detachably arranged in the placement grooves 3, the heating module 4 includes a clamping portion 6, a heating wire plate 7, a storage block 8 and a fin 9, the clamping portion 6 is connected to the heating wire plate 7, the heating wire plate 7 is connected to the storage block 8, and the storage block 8 is connected to the fin 9; a phase change material 10 is filled and arranged in the storage block 8; a pressing head assembly 1, arranged on the pressing rod, for extruding the carbon powder into shape and discharging the gas.

[0033] The circumferentially distributed placement grooves 3 provide a fixed position for the heating module 4, and in particular, the clamping portion 6 can be embedded in the placement groove 3 to achieve detachable installation of the heating module 4, which is convenient for daily maintenance, cleaning or replacement of the heating module 4, and improves the flexibility and maintenance efficiency of the equipment; a layer of anti-stick coating, such as Teflon or silicone oil coating, can be applied on the inner layer 22 to reduce the adhesion of the carbon powder after columnar molding.

[0034] The pressing head assembly 1 includes: an extrusion body 101, which is arranged at the bottom of the pressing rod; a heating ring block 102, which is arranged at the bottom of the extrusion body 101; a plurality of first exhaust channels 104, which are arranged on the outer ring at the bottom of the heating ring block 102 and the outer ring at the top of the extrusion body 101; and a plurality of second exhaust channels 103, which are arranged on the inner ring at the bottom of the heating ring block 102 and inside the extrusion body 101.

[0035] By setting up the heating ring block 102 to heat the carbon powder during the extrusion process, it is helpful to dry the carbon powder, reduce the problem of carbon powder adhesion caused by moisture, make the columnar carbon easier to separate from the mold and the pressing head surface, and improve the smoothness of demolding; by setting up the first exhaust channel 104, in the early stage of extrusion, the first exhaust channel 104 of the outer ring can quickly collect and discharge a large amount of gas, avoiding the accumulation of gas between the carbon powder and the carbon powder sealing device 2 to form an air cushion, affecting the pressure transmission and the uniform distribution of the carbon powder; by setting up the second exhaust channel 103, it is mainly responsible for discharging the gas deep inside the carbon powder.

[0036] A gap exists between the outer layer 21 and the inner layer 22, with an annular heat conducting plate 5 positioned along the inner layer 22. Fins 9 are in contact with the inner layer 22. The gap between the outer layer 21 and the inner layer 22, along with the annular heat conducting plate 5, together form an efficient heat transfer system. The annular heat conducting plate 5 evenly distributes heat transferred from the heating module 4, ensuring a uniform temperature within the inner layer 22. This is crucial for uniform heating and pyrolysis of the carbon material. The outer layer 21 performs heat exchange and protection functions, while the inner layer 22 directly participates in the molding process, facilitating heat isolation and control, preventing heat loss.

[0037] The top of the first exhaust channel 104 passes through the extruded body 101; the bottoms of the first exhaust channel 104 and the second exhaust channel 103 are both provided with microporous membranes. By providing a microporous membrane, the microporous membrane, as a filter medium, can effectively intercept fine particles, dust and particulates in volatile gases generated during the carbon forming process, ensure the cleanliness of the exhaust, reduce environmental pollution and internal pollution of the equipment, and at the same time ensure the purity and surface quality of the final product, avoid the carbon powder from being discharged through the channel during extrusion molding, and can also discharge the generated water vapor to the outside. The microporous membrane can be made of polytetrafluoroethylene, polypropylene or polyester. At the same time, the microporous membrane can play a certain pressure buffering role, helping to adjust the pressure difference between the inside of the carbon powder sealing device 2 and the outside world. Especially in the process of pyrolysis of carbon materials, the amount of gas generated and the pressure will fluctuate greatly. The microporous membrane can smooth the gas discharge and avoid the sudden pressure change from causing damage to the equipment and the molded product.

[0038] The inlets of the first exhaust channel 104 and the second exhaust channel 103 are wider than their outlets. The wide inlet design reduces resistance to gas entering the exhaust channel, while the narrow outlet increases the velocity of gas passing through it. By utilizing the Venturi effect in fluid mechanics, the gas flow velocity is enhanced, effectively guiding and accelerating the flow of gas generated within the carbon powder enclosure 2. This ensures that the large amount of gas generated during the pyrolysis and extrusion of the carbon material can be smoothly discharged, reducing internal pressure accumulation. It also helps to dynamically balance the internal pressure of the carbon powder enclosure 2, preventing damage to the carbon powder enclosure 2 or molding defects caused by excessive local pressure.

[0039] The inner wall of the first exhaust channel 104 is arranged in a wavy shape, and the second exhaust channels 103 are arranged in a staggered manner.

[0040] By setting a wavy inner wall, the turbulence of the gas can be increased when passing through the first exhaust channel 104. In order to more effectively break up and mix the gas in the channel and avoid local heat accumulation and possible blockage problems caused by gas laminar flow, the heat exchange efficiency can be improved by increasing turbulence, so that the temperature distribution inside the carbon powder sealing device 2 is more uniform, and the water vapor generated when the carbon powder is heated and formed is discharged to avoid the water vapor from being unable to be discharged and affecting the final molding of the carbon powder. It can also be set in a spiral shape and can gradually rise along the air flow direction, which helps to guide the water vapor to flow upward; by setting the second exhaust channels 103 in a staggered distribution, it can cover the bottom area of ​​the carbon powder sealing device 2 more widely, ensuring that the gas at different positions inside the carbon powder sealing device 2 can be effectively discharged, avoiding gas aggregation to form a "dead zone", and can significantly improve the uniformity and efficiency of the exhaust, which helps to maintain the stability of the internal pressure of the carbon powder sealing device 2 and reduce the internal stress concentration problem caused by gas accumulation, thereby improving the quality and consistency of the columnar carbon product.

[0041] The outlet of the second exhaust channel 103 is connected to the first exhaust channel 104. When the gas is discharged through the second exhaust channel 103, it can directly enter the first exhaust channel 104 and then be quickly discharged, thereby avoiding the accumulation and circulation of gas inside the carbon powder sealing device 2, improving the continuity and efficiency of exhaust. At the same time, the second exhaust channel 103 can absorb gas at different positions in the carbon powder sealing device 2 and discharge it outward through the first exhaust channel 104, without affecting the normal use of the pressing head assembly 1.

[0042] The clamping part 6 includes: a clamping block 61, which is arranged on the heating wire plate 7; two grooves 62, which are arranged on the clamping block 61 and distributed up and down; a clamping rod 64, which is movably arranged in the groove 62; the outer layer 21 is provided with a clamping hole used in conjunction with the clamping rod 64; the outer side of the clamping rod 64 passes through the clamping block 61 and extends into the clamping hole.

[0043] By setting the groove 62, a movable space is provided for the card rod 64, so that the card rod 64 can move smoothly therein. When the limit pull plate 63 is pulled inward to drive the card rod 64 to move, the groove 62 can effectively prevent the card rod 64 from being offset or shaking, so that the card rod 64 can accurately cooperate with the card hole on the outer layer 21, thereby realizing reliable installation and disassembly of the heating module 4, and providing installation space for the tension spring 65.

[0044] The limit plate 63 is fixedly mounted on the inner side of the clamping rod 64 and is located in the groove 62. The tension spring 65 is disposed in the groove 62. The limit plate 63 serves to limit the clamping rod 64, preventing it from being completely withdrawn. At the same time, the limit plate 63 moves, driving the clamping rod 64 to move, squeezing the tension spring 65 and causing it to deform, thereby providing a reset for the clamping rod 64. The limit plate 63 is in sliding contact with the inner cavity of the groove 62. The front side of the limit plate 63 extends through the clamping block 61. It can be made of metal or a solid material, which is strong and not easily deformed.

[0045] One side of the tension spring 65 is fixedly connected to the inner side of the groove 62, and the other side is fixedly connected to the inner side of the limit plate 63. The tension spring 65 is made of heat-resistant alloy steel or stainless steel, such as chrome-vanadium steel, chrome-silicon steel, or stainless steel. Such steels have excellent high-temperature strength, elastic limit, and anti-relaxation properties. During the movement of the limit plate 63, the tension spring 65 is compressed. When the limit plate 63 is no longer acting, the tension spring 65 drives the limit plate 63 to reset.

[0046] The technical solution provided by the present invention is that when in use, the limiting pull plate 63 is pulled inward, driving the clamping rod 64 to move inward. During this process, the tension spring 65 is compressed, the heating module 4 is inserted into the placement slot 3, the limiting pull plate 63 is released, driving the clamping rod 64 to move outward, and the clamping rod 64 is inserted into the clamping hole. The heating wire plate 7 is turned on by the external controller, and the current passes through the heating wire plate 7 to generate heat. The heat is transferred to the phase change material 10 through the storage block 8, which can effectively store and release heat. The heat is then transferred to the inner layer 2 through the fin 9. 2, so that the inner layer 22 quickly reaches the working temperature. At the same time, the heating ring block 102 is turned on by the external controller, and the carbon powder is poured into the carbon powder sealing device 2. The pressing rod moves downward, driving the pressing head assembly 1 to move downward into the carbon powder sealing device 2 to extrude the carbon powder. During the extrusion molding process, the carbon powder is dried by the heating ring block 102 and the inner layer 22 to prevent the carbon powder from hanging on the wall. At the same time, the water vapor generated during the drying process is discharged outward through the first exhaust channel 104 and the second exhaust channel 103.

[0047] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
