[0044] Embodiment 1

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a mobile multi-mode pressure-maintaining device, including: a frame 1, a mounting base plate 2, a positioning component and a pressure-maintaining component.

[0046] The rack 1 serves as the supporting structure of the entire device, providing a stable foundation so that other components can be installed and operated safely and accurately. The design of the rack 1 needs to take into account sufficient strength and rigidity to withstand various forces and torques generated during the operation of the device.

[0047] The mounting base plate 2 is horizontally mounted on the frame 1; the positioning assembly is fixedly arranged on the upper side of the mounting base plate 2, and the product 100 to be pressure-maintained is arranged in the positioning assembly; the pressure-maintaining assembly is fixedly connected to the mounting base plate 2, and the pressure-maintaining assembly is arranged above the positioning assembly, and the pressure-maintaining assembly applies a downward force to the product 100 to be pressure-maintained.

[0048] The main function of the positioning assembly is to accurately fix the product to be pressurized and ensure its stable position during the pressurization process. The positioning assembly is fixed to the upper side of the mounting base plate 2 and is designed according to the shape and size of the product to meet different product requirements. The main function of the pressurization assembly is to apply a downward force to the product to be pressurized 100 placed in the positioning assembly to perform a pressurization process.

[0049] The pressure-maintaining assembly is fixedly connected to the mounting base plate 2 and is disposed above the positioning assembly to ensure that the pressure can act directly and evenly on the product.

[0050] There are multiple positioning components and pressure-maintaining components, and the pressure-maintaining components and positioning components are arranged in a one-to-one correspondence.

[0051] This embodiment adopts a multi-mode design, that is, each positioning component and pressure holding component are one-to-one corresponding, and multiple products can be pressure-held at the same time, which significantly improves production efficiency. By independently controlling each module, the pressure holding parameters can also be adjusted according to the specific needs of different products, enhancing the applicability and flexibility of the equipment.

[0052] like Figure 1 As shown, Figure 1 Two positioning components and two pressure-holding components are used, so that the pressure-holding operation can be performed on two products 100 to be pressure-held at the same time. Compared with a single-mold pressure-holding machine, the pressure-holding efficiency is improved by 100%.

[0053] In practice, multiple positioning components and pressure-maintaining components, such as 3, 4, 5, or 6, may be selected according to specific circumstances.

[0054] Embodiment 2

[0055] like Figure 2As shown, the positioning assembly includes: a first positioning block 3, a second positioning block 4, a first horizontal moving assembly 6, a second horizontal moving assembly 5, a first moving block 7 and a second moving block 8.

[0056] The first positioning block 3 and the second positioning block 4 are both installed on the mounting base plate 2, and the first positioning block 3 and the second positioning block 4 are vertically arranged; the first positioning block 3 and the second positioning block 4 are vertically formed into an L-shaped structure, and when the product 100 to be pressurized is placed in the positioning assembly, the first positioning block 3 and the second positioning block 4 limit the degrees of freedom of the product 100 to be pressurized in two directions.

[0057] The fixed ends of the first horizontal moving component 6 and the second horizontal moving component 5 are both connected to the mounting base plate 2, the moving direction of the moving end of the first horizontal moving component 6 is perpendicular to the first positioning block 3, and the moving direction of the moving end of the second horizontal moving component 5 is perpendicular to the second positioning block 4; the first moving block 7 is fixedly connected to the moving end of the first horizontal moving component 6, and the second moving block 8 is fixedly connected to the moving end of the second horizontal moving component 5; the moving blocks are driven to move by the horizontal moving components, so that the first moving block 7 and the first positioning block 3 clamp the product 100 to be pressurized, and the second moving block 8 and the second positioning block 4 also clamp the product 100 to be pressurized, thereby finally achieving the positioning of the product 100 to be pressurized.

[0058] The contact surface between the first positioning block 3 and the product 100 to be pressurized is parallel to the contact surface between the first moving block 7 and the product 100 to be pressurized, and the contact surface between the second positioning block 4 and the product 100 to be pressurized is parallel to the contact surface between the second moving block 8 and the product 100 to be pressurized. The four contact surfaces form a rectangular structure to achieve positioning of the product 100 to be pressurized, and the parallel contact surface design helps to disperse the force applied to the product during the pressurization process, avoiding local stress concentration on the product, thereby improving the uniformity of the pressurization effect and the quality of the product.

[0059] Embodiment 3

[0060] The first horizontal moving assembly 6 and the second horizontal moving assembly 5 in the second embodiment are linear motors, electric telescopic rods, hydraulic cylinders or air cylinders.

[0061] If the horizontal moving component is a cylinder, provide a specific description of it.

[0062] The first horizontal moving assembly 6 is a first positioning cylinder, and the second horizontal moving assembly 5 is a second positioning cylinder. The cylinder bodies of the first positioning cylinder and the second positioning cylinder are both installed on the mounting base plate 2. The moving direction of the rod body of the first positioning cylinder is perpendicular to the first positioning block 3, and the moving direction of the rod body of the second positioning cylinder is perpendicular to the second positioning block 4.

[0063] The first moving block 7 is fixedly connected to the rod body of the first positioning cylinder, and the second moving block 8 is fixedly connected to the rod body of the second positioning cylinder.

[0064] A holding time regulator 14 for controlling the first horizontal moving assembly 6 and the second horizontal moving assembly 5 is disposed on the mounting base plate 2 .

[0065] When the cylinder is working, the rod body is extended and retracted by controlling the inflow and outflow of gas. When the first or second moving block 8 needs to be moved, the corresponding cylinder will be activated, and the gas will be pressed into the cylinder to push the rod body to extend, or the gas will be released to retract the rod body, thereby allowing fast and accurate position adjustment.

[0066] The holding time regulator 14 provided on the mounting base plate 2 is used to control the operation time of the first and second horizontal moving components 5 (i.e., positioning cylinders), so that the operator can adjust the time for the product to maintain a specific position during the positioning process as needed, thereby optimizing the holding effect and production efficiency.

[0067] Embodiment 4

[0068] The pressure-maintaining assembly includes: a pressure-maintaining support plate 11 , a vertical moving assembly 9 and a pressure-maintaining mold 10 .

[0069] The pressure holding support plate 11 is connected to the mounting base plate 2; the fixed end of the vertical moving assembly 9 is fixedly connected to the pressure holding support plate 11, and the moving direction of the moving end of the vertical moving assembly 9 is perpendicular to the product 100 to be pressure held; the pressure holding mold 10 is connected to the moving end of the vertical moving assembly 9, and during pressure holding, the product 100 to be pressure held is placed in the pressure holding mold 10. A pressure holding time regulator 14 for controlling the vertical moving assembly 9 is provided on the mounting base plate 2.

[0070] The pressure-holding support plate 11 is used to vertically fix the vertical moving component 9. At the same time, the pressure-holding support plate 11 needs to have sufficient strength and rigidity to stably support the vertical moving component 9 and the pressure-holding mold 10 to ensure that no deformation or displacement occurs due to mechanical stress during the entire pressure-holding process.

[0071] The design of the pressure holding mold 10 is usually customized according to the shape, size and pressure holding requirements of the product to ensure that pressure can be applied evenly during the pressure holding process. The pressure holding mold 10 needs to have high wear resistance and sufficient mechanical strength to withstand repeated pressure holding cycles and high pressure environments.

[0072] At the beginning of the holding operation, the vertical moving assembly 9 is activated, so that the holding mold 10 moves downward in the vertical direction until it contacts the product 100 to be held placed in the positioning assembly and applies the required pressure. By controlling the moving speed and pressure of the vertical moving assembly 9, the size and time of the holding pressure can be accurately managed, thereby achieving the predetermined product processing quality and effect.

[0073] Embodiment 5

[0074] The vertical moving component 9 is a linear motor, an electric telescopic rod, a hydraulic cylinder or a pneumatic cylinder.

[0075] The vertical moving component 9 is a pressure-maintaining cylinder, the cylinder body of the pressure-maintaining cylinder is fixedly connected to the pressure-maintaining support plate 11, the moving direction of the rod body of the pressure-maintaining cylinder is perpendicular to the product to be pressure-maintained 100, and the pressure-maintaining mold 10 is fixedly connected to the rod body of the pressure-maintaining cylinder through a buffer spring 12, and the central axis of the buffer spring 12 is arranged parallel to the rod body of the pressure-maintaining cylinder.

[0076] The working principle of the pressure-maintaining cylinder is similar to that of the positioning cylinder and will not be elaborated in detail.

[0077] The pressure-holding mold 10 is fixedly connected to the rod of the pressure-holding cylinder through a buffer spring 12. The main function of the buffer spring 12 is to absorb and alleviate the impact and vibration generated during the pressure-holding process. This not only protects the structural integrity of the cylinder and the mold, but also improves the stability of operation and the pressure-holding quality of the product. The central axis of the buffer spring 12 is arranged parallel to the rod of the pressure-holding cylinder to ensure that the spring can remain stable during compression and release, avoiding lateral loads or offsets, thereby improving the life and reliability of the entire device.

[0078] Embodiment 6

[0079] A heating rod is installed in the pressure-holding mold 10, and a mold temperature regulator 13 for controlling the heating rod is provided on the mounting base 2. The heating rod installed in the pressure-holding mold 10 is used to provide necessary heat treatment for the product during the pressure-holding process. Heating the pressure-holding product 100 can improve the fluidity of the material, reduce internal stress, or speed up the curing process. It can be customized according to different materials and product requirements. The mold temperature regulator 13 installed on the mounting base 2 is responsible for controlling the temperature of the heating rod. By accurately adjusting the output power of the heating rod, the temperature regulator can ensure that the temperature in the mold is maintained at an optimal level to meet specific production process requirements.

[0080] The lower end of the frame 1 is connected with a steering wheel 15 and a foot cup 16. The steering wheel 15 provides the convenience of equipment movement, so that this pressure holding device can be easily moved to different production lines or work areas within the factory. The foot cup 16 is used to fix the position of the equipment when necessary to improve the stability of the equipment during operation. This design makes the equipment not only flexible in operation, but also maintains the necessary stability during the pressure holding process to prevent the pressure holding quality from being affected by movement or vibration.
