This invention relates to a uniformly dense curved polyurethane foam core material, its rotational foaming preparation method, and an antenna sandwich structure, belonging to the technical field of polymer material foaming molding and composite material structure manufacturing. In the key stage of the polyurethane mixture foaming reaction, this invention drives the mold to rotate continuously and uniformly around the central axis of the antenna surface, placing the liquid in a microgravity state where centrifugal force and gravity are balanced, eliminating density stratification and preparing a curved polyurethane foam core material with a density difference ≤5%. This core material is then composited with a fiber-reinforced resin composite skin to obtain the antenna curved sandwich structure. This invention achieves near-net-shape forming through the conformal design of the mold cavity and the antenna reflector surface, and strengthens the interface bonding by setting a film reinforcement layer between the skin and the core material. This invention effectively improves the surface accuracy stability and electrical performance consistency of the antenna reflector surface, and has the advantages of simple process, low cost, and wide applicability.

The invention belongs to the technical field of injection molding equipment, and discloses a batch injection molding device for sealing ring processing, the batch injection molding device comprises an injection molding machine, and an upper mold and a lower mold which are installed on the injection molding machine, the lower mold comprises a male mold plate and a mold core arranged on the male mold plate, the mold core comprises an insert arranged on the mold core, and the insert is arranged on the male mold plate. The insert comprises a mold core and a positioning plate, and the mold core is located in the middle of the positioning plate; the center of the mold core is a vertical cylindrical hollow area in the axis direction. The upper narrow area and the lower wide area of the middle hollow area are communicated to form the cavity formed by the sealing sleeve, the hollow area and the material handle, the cavity is communicated with the ejection piece below through the through hole in the hollow needle, and negative pressure in the ejection piece acts on the material handle, so that the central area of the material handle is adsorbed by the mold core. And meanwhile, the ejector pin is upwards jacked to upwards eject out and demould the sealing ring, so that the sealing ring is separated from the thin handle of the material handle to be snapped. And subsequent cutting procedures are reduced, and the production efficiency is improved.
