[0015] The utility model will be further clearly and completely described below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative, but not as any limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0016] It should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form, unless the context clearly indicates otherwise, and furthermore, it should be understood that when the terms "comprise" and / or "include" are used in the specification, there is a feature, step, operation, device, component and / or combination thereof.

[0017] Unless specifically stated otherwise, the relative arrangement of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that the sizes of the various parts shown in the drawings are not drawn in proportion to the actual proportions. The technology, methods and devices known to those skilled in the relevant art may not be discussed in detail, but under appropriate circumstances, the technology, methods and devices should be considered as part of the authorized description. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, not as a limitation. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0018] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0019] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0020] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0021] This utility model relates to a rear-mounted pneumatic mold clamping device for a folding machine, such as... Figure 1 As shown, the device includes a clamping component 1 rotatably mounted on one side of the mold. Specifically, the clamping component 1 is rotatably mounted on one side of the mold via a shaft 4, and the clamping component 1 has a clamping surface that matches the mold on the side close to the mold. A connecting rod 2 is mounted on the clamping component 1. One end of the connecting rod 2 is fixedly connected to the clamping component 1, and the other end is connected to a cylinder 3. The connecting rod 2 can drive the clamping component 1 to rotate under the action of the cylinder 3, so as to clamp or release the mold. Specifically, the connecting rod 2 is an L-shaped connecting rod. One end of the connecting rod 2 is fixedly connected to the clamping component 1 by a screw, and the connection position between the connecting rod 2 and the clamping component 1 is located above the shaft 4. The other end is rotatably connected to the end of the piston rod 5 of the cylinder 3.

[0022] The working principle of the rear pneumatic mold clamping device for a folding machine of this utility model is as follows:

[0023] When the clamping device needs to be clamped, the piston rod 5 of the air cylinder 3 is extended, the L-shaped connecting rod 2 moves downward around its connecting point in an arc trajectory, and the other end of the L-shaped connecting rod 2 drives the clamping piece 1 to rotate around the shaft rod 4 in an arc trajectory to the left. When the piston rod 5 is fully extended, the clamping surface of the clamping piece 1 can be tightly attached to the clamped surface of the mold, so that the clamping action is quickly realized.

[0024] When the clamping device needs to be opened, the piston rod 5 of the air cylinder 3 is retracted, the L-shaped connecting rod 2 moves upward around its connecting point in an arc trajectory, and the other end of the L-shaped connecting rod 2 drives the clamping piece 1 to move around the shaft rod 4 in an arc trajectory to the right, thereby releasing the mold.

[0025] In summary, the rear-mounted pneumatic mold clamping device of the folding machine provided by the utility model has the advantages of simple structure, convenient operation, meeting the requirements of clamping efficiency and stability, ensuring energy saving and environmental protection, great market value, and wide application.

[0026] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
