Description

Technical Field

[0001] This utility model relates to the field of composite material molding technology, and in particular to a molding die for a fishbone-type carbon fiber rib. Background Technology

[0002] Composite material molding is a manufacturing process that combines fiber reinforcement with matrix materials through specific processes to form high-performance products. The core processes include lay-up, curing / sintering, and demolding. Common methods include hand lay-up, autoclave, RTM, and automated tape lay-up. The molding process requires control of temperature, pressure, and time to ensure uniform material wetting, low porosity, and accurate dimensions. Composite material molding is widely used in aerospace, automotive, and wind power fields, and has advantages such as lightweight, high strength, and corrosion resistance.

[0003] The prior art discloses the molding of composite material ribs, which are commonly used in aircraft structural components such as wings or fuselages to support the skin, maintain the cross-sectional shape of the wing, and play a role in structural support, load transfer, and weight reduction. The ribs are often molded individually in the form of rib boxes and then manufactured by gluing and assembling tooling. However, the integral male mold has undercut details, which are inconvenient to process and make product demolding difficult. At the same time, the mold does not have a dust removal function, and impurities are easy to adhere to, thus affecting the use of the mold. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A molding die for a fishbone-type carbon fiber rib includes a flat plate, a die assembly on the flat plate, a hanging ear on the flat plate, a frame at the bottom end of the flat plate, a dust collection assembly on the flat plate, and the die assembly includes a mounting groove formed on the flat plate. A first insert is mounted on the inner wall of the mounting groove by bolts and positioning pins, and a hanging ear is provided at the end of the first insert.

By setting up a dust collection component, the flat plate can be vacuumed during mold installation to avoid impurities affecting the mold installation. At the same time, after the mold is installed, the mold can be vacuumed to improve the precision of the molded parts. Attached Figure Description

[0066] Before the mold is placed on the plate 1, the conduit 23 can be connected to the suction pipe of the vacuum cleaner. Then, hold the conduit 23 and move it along the surface of the plate 1. Impurities and dust will enter the vacuum cleaner through the suction hole 25 and the conduit 23, which makes it easy to vacuum the surface of the plate 1 and avoid impurities affecting the installation of the mold. At the same time, after the mold is installed, the mold can be vacuumed to improve the accuracy of the molded parts. When the conduit 23 is not in use, it can be inserted into the sleeve 24 for fixation, which is convenient for the next use.
