Description

Technical Field

[0001] This utility model relates to the field of vibration molding technology, and in particular to a frame structure of a vibration molding machine and the vibration molding machine itself. Background Technology

[0002] A vibration molding machine is a large-scale processing equipment, especially used in the processing of carbon products. A mixed paste is added to the mold box of the vibration molding machine, and the carbon paste is shaped by the vibration of the vibration platform. To ensure product quality, it is necessary to expel as much gas as possible from the paste. This is achieved by installing a vacuum hood above the mold box to ensure its relative airtightness, and by drawing a vacuum to expel the gas from the paste inside the mold box.

[0003] For related technology, please refer to Chinese Patent No. CN111469480B, which discloses a four-column guided vacuum pressure vibration molding machine, including a frame with four columns. The bottom of the columns is fixedly installed on a base, and a top mounting seat is fixedly installed on the top of the columns. A counterweight beam is installed between the top mounting seat and the base. The counterweight beam is slidably installed on the columns. A connecting column is fixedly installed below the counterweight beam. A vacuum hood is fitted onto the connecting column. A pressure head is fixedly installed at the bottom of the connecting column. A vibration platform is installed on the base, and a mold box is installed on the vibration platform. The mold box is located below the pressure head, and locking mechanisms are installed on both sides of the mold box on the vibration platform.

[0004] In the aforementioned technologies, the four conventional columns serve both as guides and positionsers for the counterweight beam and as supports for the entire machine. As the core support structure, they ensure the stability of the equipment during operation and prevent displacement or tilting during vibration. During vibration molding, the four columns provide precise guidance for the counterweight beam, ensuring that the beam, driving the pressure head, applies pressure smoothly to the material during vibration, thus guaranteeing molding quality. As the core support structure, the columns require enhanced rigidity and stability, resulting in an increased material cross-section. When the columns function as guides, their surfaces must be wear-resistant and smooth, requiring surface hardening and precision machining.

[0005] Given the dual function of the columns, their length necessitates an increased diameter during processing to ensure support strength, and materials with sufficient strength and hardness must be used. This is especially true for larger vibration molding machines, where both the length and diameter of the columns need to be increased. However, this increases the costs of materials, processing, transportation, and on-site installation. Furthermore, the counterweight beam slides on the column, and because the lower plane of the vacuum hood beneath the counterweight beam needs to contact and engage with the upper plane of the mold box to ensure a seal, the sliding stroke of the counterweight beam is far less than the total length of the column. This means a significant portion of the column's top and bottom length is not used for guiding, indicating that the overall length of the column is not fully utilized. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing a frame structure for a vibration molding machine and a vibration molding machine in general.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] Firstly, this utility model provides a frame structure for a vibration molding machine.

[0009] A frame structure for a vibration molding machine includes a lower base, an upper beam frame, and a support structure. The support structure includes a first support portion and a second support portion. The tops of both the first and second support portions are connected to the upper beam frame, and the bottoms of both the first and second support portions are connected to the lower base. Guide column assemblies are provided on both the first and second support portions. The first support portion includes a first pillar and a second pillar, and the second support portion includes a third pillar and a fourth pillar. The guide column assemblies are located between the first and second pillars, and between the third and fourth pillars.

[0010] The technical effect of adopting the above technical solution is as follows: the support structure provides support, ensuring the stability of the equipment during operation and preventing displacement or tilting during vibration. Specifically, it includes a first support part and a second support part arranged symmetrically. Guide column assemblies are respectively provided on the first support part and the second support part. The guide column assemblies are used to guide the up and down sliding of the counterweight beam. Compared with the traditional four-guide column structure, the main function of the guide column assembly in this utility model is not to provide support, but only to provide guidance for the counterweight beam. Therefore, on the one hand, the strength of the guide column assembly can be reduced to meet the strength requirements for guiding the counterweight beam. On the other hand, the length of the guide column assembly can be shortened to meet the stroke of the counterweight beam sliding on the guide column assembly. In this way, the effective length of the guide column assembly can be utilized to the maximum extent. When the guide column assembly plays a guiding role rather than a supporting role, the strength, length and diameter of the guide column assembly can be reduced accordingly (compared with the traditional four-guide column structure), thereby achieving the purpose of saving costs.

[0011] Furthermore, the guide column assembly includes a guide column and a lower crossbeam. The lower crossbeam is horizontally installed between the first and second pillars, and between the third and fourth pillars. The bottom end of the guide column is connected to the lower crossbeam, and the top end of the guide column extends upward and is connected to the upper beam frame.

[0012] The technical effect of adopting the above-mentioned further technical solution is as follows: the lower crossbeam is set between the first and second pillars, the top of the guide column is fixed by the upper beam frame, and the bottom of the guide column is fixed by the lower crossbeam, so as to achieve the purpose of fixing the guide column as a whole. This design shortens the length of the guide column. When the supporting structure plays a supporting role, the guide column only plays a guiding role. Its overall strength, diameter and length can be reduced accordingly compared with the traditional four-guide column structure. That is, the guide column in this utility model has a smaller diameter and shorter length, and only needs to play a guiding role, which greatly reduces the material, production, transportation and on-site installation costs of the guide column in this utility model.

[0013] Furthermore, the guide column assembly includes a guide column and a lower crossbeam. The lower crossbeam is horizontally installed between the first and second pillars, and between the third and fourth pillars. The bottom end of the guide column is connected to the lower crossbeam. The guide column assembly also includes an upper crossbeam, which is located below the upper beam frame. The top end of the guide column is connected to the upper crossbeam.

[0014] Furthermore, the upper crossbeam is horizontally installed between the first and second supports, and between the third and fourth supports.

[0015] The technical effect of adopting the above-mentioned further technical solution is that the top of the guide column is connected to the upper crossbeam, and there is a gap between the upper crossbeam and the upper beam frame, while the position of the lower crossbeam remains unchanged. This further shortens the length of the guide column, thereby reducing the cost of materials, production, transportation and on-site installation. At the same time, the length of the guide column can be further fully utilized.

[0016] Furthermore, the first, second, third, and fourth pillars are all made of structural steel profiles that meet strength requirements and are inexpensive, such as I-beams, channel steel, or steel pipes.

[0017] Furthermore, each guide post assembly includes at least one guide post.

[0018] Secondly, this utility model also provides a vibration molding machine.

[0019] A vibration molding machine includes the frame structure of the vibration molding machine described above, and also includes a counterweight beam. The counterweight beam is located between a first support part and a second support part, and both sides of the counterweight beam are slidably connected to the guide columns. The upper beam is equipped with a lifting mechanism connected to the counterweight beam, and the lower machine base is equipped with a vibration platform.

[0020] The technical advantages of the above-mentioned technical solution are as follows: The vibration molding machine includes the aforementioned support structure, which provides reliable support for the entire machine. The counterweight beam is slidably connected to the guide column. The up-and-down sliding of the counterweight beam is driven by a lifting mechanism, which is mounted on the upper beam frame and supported by the upper beam frame. Therefore, although the counterweight beam slides on the guide column, its overall weight is supported by the lifting mechanism. The guide column only provides guidance to facilitate the sliding of the counterweight beam. Thus, the strength and diameter of the guide column can be reduced compared to existing technologies, while still meeting the strength requirements. On the other hand, since the upper limit of the counterweight beam's upward movement is the upper beam frame and the lower limit of its downward movement is the upper plane of the mold box, the length of the guide column can be shortened compared to existing technologies. In other words, by reducing the strength, diameter, and length of the guide column in this invention, the guiding function of the guide column can be fully and rationally utilized, while simultaneously reducing material, production, transportation, and on-site installation costs.

[0021] Furthermore, guide sleeves are provided on both sides of the counterweight beam, the guide column passes through the guide sleeve, and the guide sleeve is slidably connected to the guide column.

[0022] The technical effect of adopting the above-mentioned further technical solution is that the guide column penetrates the guide sleeve, making the ballast beam slide more conveniently and smoothly.

[0023] Furthermore, the guide sleeve corresponds one-to-one with the guide post.

[0024] Furthermore, the lifting mechanism is a hydraulic cylinder, the piston rod of the hydraulic cylinder is connected to the counterweight beam, and the hydraulic cylinder is connected to the upper beam frame. Attached Figure Description

[0032] The principles and features of this utility model are described below with reference to all the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] This utility model discloses a frame structure for a vibration molding machine and the vibration molding machine itself.

[0034] Example 1

[0035] Reference Figure 1 This utility model discloses a frame structure for a vibration molding machine, including a lower base 24, an upper beam frame 23, and a support structure 2. The support structure 2 is a welded profile component that provides fixed support for the guide column assembly 3, ensuring stable operation of the equipment. The support structure 2 includes a first support part 21 and a second support part 22. The tops of the first support part 21 and the second support part 22 are connected to the upper beam frame 23, and the bottoms of the first support part 21 and the second support part 22 are connected to the lower base 24. Guide column assemblies 3 are respectively provided on the first support part 21 and the second support part 22. The support structure 2 is used to provide support, ensure the stability of the equipment during operation, and prevent displacement or tilting during vibration.

[0036] The first support part 21 and the second support part 22 have the same structure. The first support part 21 and the second support part 22 are located on both sides of the upper beam frame 23 and are symmetrically arranged. In this embodiment of the utility model, the first support part 21 is mainly used as an example for explanation.

[0037] The first support part 21 includes a first pillar 211 and a second pillar 212, and the second support part 22 includes a third pillar 221 and a fourth pillar 222. The top ends of the first pillar 211, the second pillar 212, the third pillar 221 and the fourth pillar 222 are fixedly connected to the lower side of the upper beam frame 23, and the bottom ends of the first pillar 211, the second pillar 212, the third pillar 221 and the fourth pillar 222 are fixedly connected to the upper side of the lower base 24 to improve the support stability of the entire support structure 2. There are two sets of guide column assemblies 3, one set is located between the first pillar 211 and the second pillar 212, and the other set is located between the third pillar 221 and the fourth pillar 222.

[0038] The guide column assembly 3 is used to guide the up and down sliding of the counterweight beam. The guide column assembly 3 specifically includes a guide column 31 and a lower crossbeam 33. The lower crossbeam 33 is horizontally installed between the first support column 211 and the second support column 212, and between the third support column 221 and the fourth support column 222. The lower crossbeam 33 is located at the lower middle position of the first support column 211 and the second support column 212, and at the lower middle position of the third support column 221 and the fourth support column 222. The bottom end of the guide column 31 is connected to the lower crossbeam 33, and the top end of the guide column 31 extends upward to the lower side of the upper beam frame 23 and is connected to the upper beam frame 23.

[0039] Compared to the traditional four-column structure, the main function of the guide column 31 in this embodiment is not to provide support, but to guide. Therefore, the length of the guide column 31 is shortened, and the counterweight beam 4 is slidably mounted on the guide column 31. The guide column 31 is used to guide the up and down sliding of the counterweight beam, and the length of the guide column 31 only needs to meet the stroke of the counterweight beam on the guide column 31. This can make greater use of the effective length of the guide column 31. When the guide column 31 plays a guiding role rather than a supporting role, the strength, length and diameter of the guide column 31 can be shortened accordingly (compared to the traditional four-column structure), thereby achieving the purpose of saving costs.

[0040] Specifically, traditional four-guide-column structures serve both guiding and positioning functions as well as providing fixed support. Therefore, the four guide columns have large diameters and long lengths, resulting in high costs for materials, processing, transportation, and on-site installation. In this structure, the support structure 2 provides fixed support, while the four guide columns 31 primarily serve guiding and positioning functions. The length of the guide columns 31 only needs to meet the travel distance of the counterweight beam, making them only half the length of the original columns, and their diameter is reduced to two-thirds of the original, significantly lowering material and processing costs. Simultaneously, the supporting components can be manufactured using structural steel profiles, further reducing material, manufacturing, transportation, and on-site installation costs. Therefore, compared to traditional four-guide-column structures, this new technology significantly reduces costs.

[0041] At least one guide post 31 is provided on each side. In this embodiment of the invention, four guide posts 31 are provided, arranged symmetrically in pairs between the first support column 211 and the second support column 212, and between the third support column 221 and the fourth support column 222. That is, two guide posts 31 are provided between the first support column 211 and the second support column 212, and two guide posts 31 are also provided between the third support column 221 and the fourth support column 222. When the counterweight beam 4 slides on the guide posts 31, the stability of the counterweight beam 4 during sliding can be further improved. In this embodiment of the invention, when the guide posts 31 are connected to the upper beam frame 23 and the lower crossbeam 33, they can be connected by flanges to improve the stability of the guide posts 31.

[0042] Example 2

[0043] Reference Figure 2 The main difference between Embodiment 2 and Embodiment 1 is that: the guide column assembly 3 includes a guide column 31 and a lower crossbeam 33. The lower crossbeam 33 is horizontally installed between the first support column 211 and the second support column 212, and between the third support column 221 and the fourth support column 222. The bottom end of the guide column 31 is connected to the lower crossbeam 33. The guide column assembly 3 also includes an upper crossbeam 32, which is located below the upper beam frame 23. The top end of the guide column 31 is connected to the upper crossbeam 32. The upper crossbeam 32 is horizontally installed between the first support column 211 and the second support column 212. Between the second pillar 212 and between the third pillar 221 and the fourth pillar 222, specifically, the upper crossbeam 32 is located above the middle of the first pillar 211 and the second pillar 212, and above the middle of the third pillar 221 and the fourth pillar 222, and there is a gap between the upper crossbeam 32 and the lower crossbeam 33. The top of the guide column 31 extends upward to the lower side of the upper crossbeam 32 and is fixedly connected to the upper crossbeam 32. This design can further shorten the length of the guide column 31 and reduce material, production, transportation and on-site installation costs.

[0044] There is a gap between the upper crossbeam 32 and the upper beam frame 23, which further shortens the length of the guide column 31.

[0045] Taking a vibration molding machine for producing carbon anode blocks with dimensions of 1900mm in length, 1010mm in width, and 700mm in height as an example, the existing four-column guide and four-column support structure has guide columns that are 7600mm long and Φ350mm in diameter, requiring a material of 35CrMo. The guide columns as a whole must meet high requirements for surface roughness and support strength. However, with the technical solution of this utility model, the guide columns are only 3000-4000mm long and Φ230mm in diameter. This guide column 31 not only saves more than 80% of the material compared to the original material, but also has lower requirements for processing equipment, greatly reducing processing costs. Furthermore, the support column material used is structural steel profiles, whether it is I-beams, channel steel, or steel pipes. Not only are the material and surface roughness requirements lower, but the materials can also be purchased, cut, manufactured, and installed on-site, greatly saving on material, manufacturing, transportation, and on-site installation costs.

[0046] This utility model embodiment also discloses a vibration molding machine.

[0047] Reference Figures 3-4 A vibration molding machine includes a frame structure, with a support structure 2 providing support. The machine also includes a counterweight beam 4 located between a first support portion 21 and a second support portion 22, with both sides of the counterweight beam 4 slidably connected to guide columns 31. An upper beam frame 23 is equipped with a lifting mechanism 1 connected to the counterweight beam 4. The overall weight of the counterweight beam 4 is supported by the lifting mechanism 1, and the sliding of the counterweight beam 4 is driven by the lifting mechanism 1. The lifting mechanism 1 is mounted on the upper beam frame 23, which provides support for it. A vibration platform 7 and a mold box 6 are mounted on the lower machine base 24. In this embodiment, the guide columns 31 are located between the upper crossbeam 32 and the lower crossbeam 33.

[0048] The guide column 31 only serves to guide the movement of the counterweight beam 4. The main structure, consisting of the lower base 24, upper beam frame 23, and support structure 2, bears the load for the entire machine. Therefore, compared with the prior art, the size (such as diameter) of the guide column 31 can be significantly reduced. On the other hand, since the maximum upward movement of the counterweight beam 4 is the upper crossbeam 32 and the maximum downward movement is the upper plane of the mold box 6, the length of the guide column 31 can be significantly shortened compared with the prior art. Therefore, compared with the existing four-guide-column technology, the present invention can significantly reduce material, manufacturing, transportation, and on-site installation costs.

[0049] The lifting mechanism 1 is a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the counterweight beam 4, and the cylinder body is connected to the upper beam frame 23. The vertical sliding of the counterweight beam 4 is controlled by the extension and retraction of the piston rod. In this embodiment of the present invention, a flexible adjustable constant pressure mechanism can also be installed above the counterweight beam 4. This mechanism is not specifically described in this embodiment, but can be found in the published patent CN111469480B.

[0050] The two sides of the counterweight beam 4 are respectively provided with guide sleeves 5. The number and position of the guide sleeves 5 correspond one-to-one with those of the guide posts 31. The guide posts 31 pass through the guide sleeves 5, and the guide sleeves 5 are slidably connected to the guide posts 31. Lubricant can be added to the guide sleeves 5 to make the guide sleeves 5 slide more conveniently and smoothly.

[0051] Example 4

[0052] Reference Figures 5-6 The main difference between Embodiment 4 and Embodiment 3 is that the vibration molding machine includes the frame structure of the aforementioned vibration molding machine. The support structure 2 in the frame structure provides support. The top of the guide column 31 in the vibration molding machine extends upward and connects to the upper beam frame 23. With this connection method, the maximum upward sliding position of the counterweight beam 4 is the upper beam frame 23, and the maximum downward sliding position is the upper plane of the mold box 6. Therefore, the length of the guide column 31 can be significantly shortened compared to existing technologies. Thus, compared to existing four-guide-column technologies, the technology of this invention can significantly reduce material, manufacturing, transportation, and on-site installation costs.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
