Embodiment 1
[0071] Such as image 3 As shown, the embodiment of the present invention provides a molding die for an I-shaped composite material member with a closed structure, and the forming mold can form an I-shaped composite material member with a closed structure. In this embodiment, for the sake of description, the cavity with the closed structure is defined as the right cavity, which is only determined based on the relative position of the cavity with the closed structure when the I-shaped composite material member is in a state (see image 3 As shown, the cavity with the closing structure is located on the right side of the current viewing angle), which is not limited thereto.
[0072] see image 3 As shown, in this embodiment, the forming mold includes an upper mold 1 , a lower mold 2 , a right core mold 3 and a left core mold 4 . Wherein, the lower side of the upper mold 1 has three lower protrusions, and the three lower protrusions are arranged at intervals. An upper accommod...
Embodiment 2
[0084] The second embodiment provides a method for forming an I-shaped composite member with a closing structure. The forming method uses any one of the forming molds in the first embodiment, and includes the following steps:
[0085] S1. Laying prepreg:
[0086] First, before assembling each part of the forming mold, refer to 4 and Figure 5 As shown, respectively on the upper molding surface, the lower molding surface, the upper side, the lower side and the right side of the left mold core protrusion 42, the upper side of the upper right silicone rubber part 5, the lower side of the lower right silicone rubber part 6 and The prepreg 201 is laid on the left side of the right mold core protruding portion 32 .
[0087] S2. Combined mold:
[0088] see Figure 6 As shown, the lower ends of the left core protrusion 42 and the right core protrusion 32 after step S1 are installed in the two lower housing grooves respectively, and the prepreg on the right side of the left core pro...
Embodiment 3
[0099] see Figure 7 As shown, Embodiment 3 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the molding die in Embodiment 3 is used to form a type-shaped composite material member with two closing structures. The upper side and the lower side of the core protrusion 42 are all inclined, from the left core body 41 to the right side of the left core protrusion 42, the distance between the upper side and the lower side of the left core protrusion 42 Gradually shrink, and on the upper side and the lower side of the left mold core protrusion 42, the upper left silicone rubber part 7 and the lower left silicone rubber part 8 are respectively set, the upper side of the upper left silicone rubber part 7, and the lower left silicone rubber part 8 The lower side of the mold core and the right side of the left mold core protrusion 42 are matched with the inner cavity surface of the left cavity of the I-shaped composite material comp...
