Abstract
Description
Technical Field
[0001] This utility model belongs to the field of molding equipment technology, and relates to a molding equipment for the triangular port of an aircraft air intake with a sequential demolding mechanism for protruding modules. Background Technology
[0002] Aircraft air intakes supply the air needed for the aircraft's engines to operate, directly affecting engine efficiency. They play a crucial role in engine proper functioning and thrust, thus significantly impacting aircraft performance, especially fighter jets. Currently, commonly used aircraft air intakes primarily come in two structural forms: sheet metal composite structures and integral composite material structures. Because air passes through the inner surface of the air intake, extremely high requirements are placed on the smoothness and shape precision of the inner surfaces of the components.
[0003] Currently, the molding equipment used to produce this air intake mainly consists of two cores and several mounting and positioning blocks. The two cores are installed and fixed along the axial direction of the air intake, and positioning holes and screw fixing holes are designed on each side of the cores. The various components are mainly installed and fixed by connecting and fixing the cores. The two large core components themselves are fixed together by special bolts in the middle. The large size and weight of the two large core components ultimately increase the difficulty of internal demolding. Utility Model Content

The external plate-like connecting block assembly 3 includes a side arc-shaped connecting block 5, a top connecting block 13, and a bottom connecting block 14.

[0035] In this embodiment, the internal sheet-like core mold assembly 2 and the external plate-like connecting block assembly 3 are combined and assembled with each other. The sheet-like core mold is small in size and light in weight, which can effectively improve the work efficiency during assembly and disassembly.
[0036] Furthermore, the two sides of the first lower bottom surface 9 are fixedly connected to the two sides of the first upper arc surface 6, and the two sides of the second lower bottom surface 10 are fixedly connected to the two sides of the second upper arc surface 7 and the third upper arc surface 8 through the side bottom surface 11.

The other set of side arc-shaped connecting blocks 5 is fixedly installed at the junction of the second upper arc surface 7 and the third upper arc surface 8 with the second lower bottom surface 10.
[0039] In this embodiment, the side arc-shaped connecting block 5 is used to connect the upper top surface 4 and the lower bottom surface 12, thereby improving the strength of the connection between the upper top surface 4 and the lower bottom surface 12.
[0040] Furthermore, the bottom connecting block 14 includes a horizontal connecting block 15 and a vertical connecting block 16. There are two sets of horizontal connecting blocks 15 and four sets of vertical connecting blocks 16.

[0041] In this embodiment, the connection strength between the bottom surfaces 12 can be improved by using the horizontal connecting block 15 and the vertical connecting block 16.
[0042] Furthermore, the longitudinal connecting blocks 16 are uniformly fixed between the two transverse connecting blocks 15.
[0043] In this embodiment, the longitudinal connecting block 16 is used to connect the transverse connecting block 15, which can improve the strength between the longitudinal connecting block 16 and the transverse connecting block 15.
[0044] Furthermore, the two sides of the transverse connecting block 15 are fixedly provided with connecting edges 17, and both ends of the longitudinal connecting block 16 are fixedly overlapped on the connecting edges 17 of the transverse connecting block 15.

[0049] In this embodiment, the side arc-shaped connecting block 5, the top connecting block 13, and the bottom connecting block 14 can improve strength through a T-shaped structure.
[0050] The working principle of this utility model is as follows:
[0051] In use, this invention first assembles the internal sheet-like core mold assembly 2 by connecting it with the external plate-like connecting block assembly 3. The composite material is then laid up on the surface of the aircraft air intake triangular end molding equipment. After vacuuming, heating and pressurizing are applied to allow the composite material to adhere to the surface of the molding equipment. The equipment is then heated and cured, and finally cooled before being removed to obtain the complete aircraft air intake triangular end product. The invention employs segmented cylindrical first upper arc surface 6, second upper arc surface 7, and third upper arc surface 8, as well as a first lower bottom surface 9, second lower bottom surface 10, and side bottom surface 11. Each segment is assembled from sheet-like core molds. The small size and light weight of each sheet-like core mold effectively improves the efficiency of assembly and disassembly, and reduces the difficulty of demolding.
