Embodiment 1

[0021] Such as figure 1 As shown, in this embodiment, a multi-reinforced skin co-curing mold combined with a positioning frame and multiple female molds includes a support frame 1 on which the upper surface forms a working platform to place the skin, and several legs are provided at the bottom, and through the legs The positioning frame 2 detachably installed on the working platform and several female molds 3 arranged on the positioning frame 2 to position the ribs. When in use, the skin is placed on the working platform of the support frame 1, the positioning frame 2 is placed on the skin and the legs of the positioning frame 2 are connected with the working platform. Since the positioning frame 2 is detachably installed on the working platform, the positioning frame 2 has a relatively fixed position relative to the working platform, and the positioning frame 2 is used as a positioning reference to position the skin. In this embodiment, the surface of the support foot close ...

Embodiment 2

[0023] On the basis of the above embodiments, in this embodiment, the positioning frame 2 is screwed to the supporting frame 1 . Utilize screw connection to realize detachable function. In order to realize threaded connection, flanges or plates with holes are provided on the feet, threaded holes are provided on the support frame 1, and screws are installed through the flanges or holes to cooperate with the threaded holes during installation. In this embodiment, at least two screw connections are provided. When it is necessary to use the female mold 3 to compress the skin, the screw connection between the positioning frame 2 and the support frame 1 is used to provide a compressive force for pressing the skin. In this embodiment, other parts not described are the same as those in the foregoing embodiments, so details are not repeated here.

Embodiment 3

[0025] On the basis of the above embodiments, in this embodiment, a positioning pin A is connected between the positioning frame 2 and the supporting frame 1 . Corresponding pin holes are respectively provided on the positioning frame 2 and the supporting frame 1 to facilitate the installation of the positioning pin A, and the positioning accuracy of the positioning frame 2 and the supporting frame 1 can be improved by using the positioning pin A. Therefore, it is beneficial to improve the positioning accuracy of the skin and the accuracy of the relative position between the skin and the ribs, thereby helping to ensure the quality of the bonding. In this embodiment, other parts not described are the same as those in the foregoing embodiments, so details are not repeated here.

Abstract

The invention discloses a multi-rib and skin co-curing mold combining a positioning frame and multiple female mold bodies. The multi-rib and skin co-curing mold combining the positioning frame and themultiple female mold bodies comprises a supporting frame, the positioning frame and the multiple female mold bodies, wherein a working platform for holding a skin is formed on the upper surface of the supporting frame; a plurality of supporting feet are arranged on the bottom of the positioning frame, and the positioning frame is detachably installed on the working platform through the supportingfeet; and the female mold bodies are arranged on the positioning frame so as to position ribs. The multi-rib and skin co-curing mold combining the positioning frame and the multiple female mold bodies has the beneficial effects that a special fixture is provided for glue joint of the skin and the ribs, accurate positioning of the skin and the ribs can be achieved, and thus the glue joint qualityof the skin and the ribs is improved. In addition, the multi-rib and skin co-curing mold combining the positioning frame and the multiple female mold bodies is simple in structure, convenient to use,beneficial for one-time forming so as to simplify processing technologies, and beneficial for improving glue joint efficiency.

Description

technical field [0001] The invention relates to the field of molds, in particular to a multi-rib skin co-curing mold combined with a positioning frame and multiple female molds. Background technique [0002] At present, the application area of ​​composite materials in civil and military aircraft continues to increase, the performance requirements continue to increase, and more and more applications are applied to the main load-bearing structures. Therefore, the structure of composite material components is becoming more and more complex, and the requirements for shape accuracy and the position, shape, and molding quality of each part inside the entire component are getting higher and higher. At the same time, these composite components also need to be glued or riveted with other parts to form a closed overall box together. Therefore, the position accuracy and surface quality of the parts in the formed composite member, that is, the ribs, are required to meet the requirement...
