The 16-cavity bottom cover mold is a high-capacity main model designed for large-scale mass production. Adopting a compact mechanical layout with 16 cavities, the mold features evenly and symmetrically arranged cavities, ensuring balanced overall stress during Injection Molding. This effectively avoids mold deformation and precision deviation caused by unbalanced loads, guaranteeing stability in long-term mass production. The gating system adopts a combination design of Hot Runner and needle valve gate, enabling precise and uniform distribution of plastic melt. The filling speed and pressure of each cavity are consistent, and the dimensional error of the 16 molded bottom covers is strictly controlled within 0.05mm, meeting high-precision assembly requirements. The core and cavity adopt a split modular structure, allowing separate disassembly and replacement of wear parts without overall maintenance, reducing maintenance costs by more than 60% compared with traditional molds. The cavity surface is treated with a professional hard film coating, increasing wear resistance by 3 times compared with ordinary molds and extending the service life to 1.2 million cycles, helping enterprises achieve efficient and low-cost large-scale production of bottom covers.

Design Features: Adopts a compact mechanical layout of sixteen cavities in one mold, with uniform cavity arrangement. The gating system is equipped with a hot runner + needle valve gate design to achieve precise distribution of plastic melt. The core and cavity adopt an inlaid structure, and the cavity surface is treated with a hard film coating. 

Core Parameters: The force on the mold is balanced during injection molding, the filling speed of each cavity is consistent, and the dimensional error of the 16 formed bottom covers is controlled within 0.05mm. The wear resistance of the cavity is increased by 3 times, and the service life is extended to 1.2 million cycles. 

Advantages: It can effectively avoid mold deformation caused by eccentric loading. Vulnerable parts can be replaced separately, reducing maintenance costs by more than 60%, and realizing efficient and low-cost production of bottom covers.
