The 2‑cavity unilateral injection aviation plug mold is a precision tool designed for manufacturing high‑reliability electrical connectors used in aerospace and related fields. It is configured to produce two identical plug components per cycle, improving production efficiency while maintaining strict dimensional and performance requirements.This mold adopts a unilateral injection structure, meaning the melt is introduced from one side of the mold rather than through a central gate system. The unilateral layout simplifies the runner design, reduces material waste, and allows for more compact mold dimensions. It also facilitates a more balanced flow to each cavity when properly engineered, ensuring uniform filling, consistent density, and reduced internal stress in the molded plugs.Each of the two cavities is machined with tight tolerances to ensure precise positioning of contact interfaces, sealing features, and locking structures commonly found in aviation plugs. Core and cavity inserts are typically manufactured from high‑quality mold steels with excellent wear and corrosion resistance. Surface treatments or coatings may be applied to reduce friction, extend service life, and improve demolding performance, especially when molding high‑temperature or reinforced engineering plastics.The gate and runner system is carefully designed to accommodate the rheological characteristics of aerospace‑grade resins, such as high‑temperature thermoplastics and flame‑retardant materials. Attention is given to gate location and size to minimize weld lines and air traps in critical sealing or contact areas. Venting channels are incorporated to allow trapped air and gases to escape during injection, thereby avoiding burn marks, short shots, or internal voids.An efficient cooling system is integrated into the mold, with cooling channels arranged around core features and thick‑wall regions of the part. Stable and uniform temperature control shortens cycle times and helps maintain tight dimensional tolerances. Where necessary, conformal cooling or baffle and bubbler arrangements may be used to address localized hot spots.The mold structure typically includes a robust guiding system, precision alignment features, and wear‑resistant components in high‑motion areas, such as slides or lifters, to form undercuts and complex external geometries of the plug shell. Ejection is usually carried out by ejector pins, sleeves, or plates positioned to avoid deformation of delicate features, such as pin holes, keyways, and sealing lips.In application, the 2‑cavity unilateral injection aviation plug mold supports stable mass production of connectors that must withstand vibration, temperature extremes, and stringent electrical and mechanical performance standards. Its design emphasizes repeatability, long service life, and ease of maintenance, making it suitable for continuous operation in demanding industrial environments.
