The housing is disposed on the frame and has a receiving cavity with an opening at one end along a first direction. The plug is disposed on one side of the housing along the first direction and serves to close the opening. The drive assembly is disposed on the frame and is used to drive the plug to move along the first direction, thereby closing or opening the opening. The first and second guide members are arranged along a second direction and extend along the first direction. Viewed along a third direction, the plug is located between the first and second guide members, and the first, second, and third directions are perpendicular to each other.

[0008] The isostatic pressing device provided in this application, through the cooperation of the first guide member and the second guide member, can guide the plug to move smoothly back and forth in the first direction when the drive assembly drives the plug to move in the first direction, thereby improving the concentricity of the plug and the housing, thus improving the stability and sealing of the plug and the housing after installation, reducing wear caused by misalignment between the plug and the housing, extending the service life of the isostatic pressing device, and improving the reliability of the isostatic pressing device.

[0009] According to one embodiment of this application, the second guide member includes a first limiting member and a first guide rod. The first limiting member is fixed to the frame; the first guide rod is connected to the movable member and configured to move relative to the first limiting member along a first direction.

[0010] In these alternative embodiments, the first guide rod moves synchronously with the movable component, which not only guides the movement of the movable component but also improves its stability.

The third guide member is connected to the movable member and extends along a first direction. When viewed along a third direction, the plug is located between the third guide member and the second guide member.

[0020] In these alternative embodiments, a first guide member, a third guide member, and a second guide member are sequentially provided along the second direction. When the drive member is driven, the three guide members guide the plug to move smoothly back and forth in the first direction, further improving the concentricity of the plug and the housing.

[0021] According to one embodiment of this application, the third guide member includes a second limiting member and a second guide rod. The second limiting member is fixed to the frame; the second guide rod is connected to the movable member and configured to move relative to the second limiting member in a first direction.

[0022] In these alternative embodiments, the second guide rod has the same structure as the third guide rod, which is easy to process and manufacture, and saves manufacturing costs.

[0023] According to one embodiment of this application, the third guide member further includes a movable support connected to the first guide rod and the second guide rod; the drive assembly drives the movable support and causes the first guide rod and the second guide rod to move synchronously along a first direction.

[0024] In these alternative embodiments, the movable bracket can drive the first guide rod and the second guide rod to move synchronously along the first direction, and also cause the moving parts to move synchronously along the first direction, thereby improving the consistency of guidance. Furthermore, the drive assembly directly drives the movable bracket, reducing wear on the moving parts.

[0053] Currently, judging from market trends, the application of batteries is becoming increasingly widespread. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace, among other fields.

[0054] Solid-state batteries are batteries that use solid electrodes and solid electrolytes. They offer high energy density, superior safety, and greater stability, making them a promising technology in the battery field. Isostatic pressing (IPC) is an important process in solid-state battery fabrication, improving ion channels at the solid-solid interface. By placing the solid-state battery in a sealed chamber filled with a pressurized medium and applying equal pressure, the distance between molecules is reduced and the density increased without altering its shape, thus improving the battery's physical properties and achieving densification. In related technologies, plugs are used to cover the opening of the chamber to house the solid-state battery. However, during the process of closing the opening, the plugs are prone to tilting and scraping against it, causing collisions with the chamber and exacerbating wear on the plugs and the opening. This can lead to risks such as oil leakage, oil spraying, and chamber pressurization failure in the IPC apparatus, reducing its reliability.

[0055] The isostatic pressing device provided in this application, through the cooperation of the first guide member and the second guide member, can guide the plug to move smoothly back and forth in the first direction when the drive assembly drives the plug to move in the first direction, thereby improving the concentricity of the plug and the housing, thus improving the stability and sealing of the plug and the housing after installation, reducing wear caused by misalignment between the plug and the housing, extending the service life of the isostatic pressing device, and improving the reliability of the isostatic pressing device.

[0056] For ease of explanation, the following embodiments use an isostatic pressure device according to an embodiment of this application as an example.

Furthermore, the first limiting member 61 and the first guide rod 62 simplify the overall structure of the second guide member 6 and facilitate its manufacturing.

[0084] According to one embodiment of this application, as shown in FIG4, the first limiting member 61 is provided with a through hole 611 along the first direction x, and the first guide rod 62 passes through the through hole 611 and moves within the through hole 611.

The first guide rod 62 passes through the through holes 611 of the two first limiting members 61 and moves along the first direction x within the through holes 611.

[0086] In these alternative embodiments, the cooperation between the through hole 611 and the first guide rod 62 provides a movement path for the movement of the first guide rod 62, enabling the first guide rod 62 to move linearly along the first direction x, thereby improving the smoothness of the operation of the first guide rod 62.
