[0038] The connecting body 32 is connected to the support member 1, and the working end 31 extends in a direction away from the support member 1. The connecting body 32 is provided with a threaded hole, and the threaded hole and the working end 31 are arranged relatively to each other. The movable clamping member 4 is specifically a clamping bolt, and the clamping bolt and the threaded hole are threadedly matched so that the relative surfaces of the clamping bolt and the working end 31 clamp the flange structure.

[0039] In a specific implementation, the clamping base 3 specifically includes a working end 31 and a connecting body 32 connected to each other. The connecting body 32 is used to connect with the support member 1 to fix the clamping base 3 to the support member 1. At the same time, the working end 31 of the clamping base 3 extends in a direction away from the support member 1.

[0040] A threaded hole is provided on the connecting body 32, and the threaded hole and the working end 31 are arranged opposite to each other; at the same time, the movable clamping member 4 is specifically a clamping bolt, and the threads of the clamping bolt and the threaded hole on the connecting body 32 are matched, so that the relative surfaces of the clamping bolt and the working end 31 jointly clamp the flanging structure.

[0041] It should be noted that the specific structure of the connector 32 is not limited in this embodiment and depends on the specific implementation situation.

[0042] In this embodiment, the clamping base is specifically composed of a working end and a connecting body, and combined with a clamping bolt as a movable clamping member, the clamping bolt and the relative surfaces of the working end can jointly clamp the flanging structure to facilitate demoulding of the flanging structure.

The first vertical section 33 is connected to the working end 31, the second vertical section 34 is arranged on the top of the first vertical section 33, and both the second vertical section 34 and the first vertical section 33 extend in the vertical direction, and the relative position between the two is adjustable. By changing the relative position of the second vertical section 34 and the first vertical section 33, the clamping depth of the clamping assembly 2 on the flanging structure can be changed.

[0045] Furthermore, the transverse extension section 35 is disposed on the second vertical section 34 , and the threaded hole is disposed on the transverse extension section 35 , so that the threaded hole and the working end 31 are disposed opposite to each other.

[0046] In this embodiment, the connecting body is composed of a first vertical section, a second vertical section and a transverse extension section. The threaded hole is arranged in the transverse extension section, which can better realize the clamping of the flange structure by the relative surface of the clamping bolt corresponding to the threaded hole and the working end; the relative position of the second vertical section and the first vertical section is adjustable, which can change the clamping depth of the clamping assembly on the flange structure.

[0047] Based on the above embodiments, in some embodiments, a clamping sleeve 36 is provided at the end of the clamping bolt facing the working end 31, and the clamping sleeve 36 includes a barrel and a clamping end face, the barrel and the clamping bolt are detachably connected, the clamping end face and the working end 31 are arranged opposite to each other, and the end area of ​​the clamping end face facing the working end 31 is larger than the cross-sectional area of ​​the clamping bolt.

[0048] In a specific implementation, a clamping sleeve 36 is provided at the end of the clamping bolt facing the working end 31. The clamping sleeve 36 is composed of a barrel and a clamping end face. The barrel and the clamping bolt are detachably connected, and can also be fixedly connected by gluing or welding; the clamping end face and the working end 31 are arranged opposite to each other, and the end area of ​​the clamping end face facing the working end 31 is larger than the cross-sectional area of ​​the clamping bolt, thereby increasing the contact area between the clamping bolt and the flange structure, and preventing damage to the flange structure during demoulding.

[0049] Figure 3 The structure diagram of a first vertical section provided by an embodiment of the utility model. Based on the above embodiment, Figure 3As shown, in some embodiments, the first vertical section 33 is stepped, including a first step body 331 and a second step body 332, the second step body 332 is located above the first step body 331, the first step body 331 and the second step body 332 are flush with the sides facing the support member 1, the side of the first step body 331 away from the support member 1 protrudes more than the side of the second step body 332 away from the support member 1, and the working end 31 is arranged above the first step body 331 and is connected to the second step body 332.

[0050] In a specific implementation, in order to better support the working end 31, the first vertical section 33 of the connecting body 32 is specifically stepped, including a first step body 331 and a second step body 332. The second step body 332 is located above the first step body 331, and the first step body 331 and the second step body 332 are flush with each other on the side facing the support member 1. The side of the first step body 331 facing away from the support member 1 is more protruding than the side of the second step body 332 facing away from the support member 1. The working end 31 is arranged above the first step body 331 and connected to the second step body 332, so that the upper surface of the first step body 331 is used to support the working end 31 to ensure the reliability of the connection.

[0051] On the basis of the above embodiments, in some embodiments, the clamping end face and the working end 31 are both provided with rubber material 37. By providing the rubber material 37 on both the clamping end face and the working end 31, it is possible to effectively prevent the clamping assembly 2 from sliding when clamping the flange structure, thereby playing a role of anti-slip fixation. It is understandable that other materials with anti-slip function may be selected in specific implementation, such as polyvinyl chloride gaskets or polyurethane anti-slip gaskets, etc., which are not limited in this embodiment. In addition, in this embodiment, there is no limitation on the specific shape of the rubber material 37. For example, in order to enhance the anti-slip effect, a groove structure may be provided on the surface of the rubber material 37, thereby improving the anti-slip performance of the rubber material 37.

[0052] On the basis of the above embodiments, in some embodiments, the clamping assembly 2 further includes: a hanging ring 38;

[0053] The lifting ring 38 is fixed to the second vertical section 34;

[0054] The lifting ring 38 is connected to the main hook of the overhead travelling vehicle through a lifting belt.

[0055] In the specific implementation, in order to realize the movement of the demoulding device of the flange structure in the demoulding direction, a lifting ring 38 is specifically provided on the second vertical section 34 of the clamping assembly 2, and the lifting ring 38 is connected to the main hook of the overhead travelling crane through a lifting belt. In this way, when the overhead travelling crane is started to slowly lift, the main hook of the overhead travelling crane drives the clamping assembly 2 to move in the demoulding direction, and simultaneously drives the support member 1 to move in the demoulding direction, thereby realizing the demoulding of the flange structure.

[0056] On the basis of the above embodiments, in some embodiments, the support member 1 includes a support rod having two retractable ends, and a clamping assembly 2 is provided at either end.

[0057] In order to adapt to the demoulding of flange structures of different sizes, in this embodiment, the support member 1 is specifically a support rod, which has two retractable ends, and a clamping assembly 2 is provided at each end. The support rod controls the distance between the two clamping assemblies 2 by adjusting the length of the telescopic extension, so as to adapt to the flange structure of corresponding size. In this embodiment, there is no restriction on the specific retractable manner of the support rod, for example, the support rod can be a lead screw or mutually nested joint arms, etc., which is not limited in this embodiment.

[0058] On the basis of the above embodiments, in some embodiments, the demoulding device of the flange structure further includes: a plurality of angle adjustment units; each angle adjustment unit corresponds to each clamping assembly 2 one by one;

[0059] The fixed end of the angle adjustment unit is connected to the support member 1 , and the movable end of the angle adjustment unit is connected to the corresponding clamping assembly 2 .

[0060] In a specific implementation, there are some flanging structures with different flanging angles. In order to realize the demoulding of these flanging structures, the demoulding device of the flanging structure in this embodiment also includes a plurality of angle adjustment units; each angle adjustment unit corresponds to each clamping assembly 2 one by one; the fixed end of the angle adjustment unit is connected to the support member 1, and the movable end of the angle adjustment unit is connected to the corresponding clamping assembly 2. When the angle adjustment unit adjusts its own angle, an angle can be created between the corresponding clamping assembly 2 and the support member 1, thereby adapting to the flanging angle of the flanging structure and better clamping the flanging structure. In this embodiment, there is no restriction on the adjustable angle range of the angle adjustment unit. For example, the angle range can be set to plus or minus 45 degrees, depending on the specific implementation situation.

[0061] In order to improve the clamping stability, based on the above embodiments, in some embodiments, the support member 1 includes at least two support rods, the two support rods are distributed in a cross shape, and the support rods are provided with movable joints, and different support rods are connected by the movable joints.

[0062] It is understandable that the demoulding device of the flange structure composed of at least two support rods has at least four clamping assemblies 2. Since the number of clamping assemblies 2 is increased, it can be more stable when clamping the flange structure, and more stable when demoulding, and can effectively prevent the flange structure from falling off or being damaged. At the same time, the support rods are provided with movable joints, and different support rods are connected by movable joints, which can further expand the number of support rods, that is, increase the number of clamping assemblies 2, thereby further improving the clamping stability.

[0063] The above is a detailed introduction to a demoulding device with a flanging structure provided by the utility model. The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the embodiments can be referenced to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the utility model.

[0064] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
