Number of mold cavities: 1 Mold material: 718H/P20 Product weight: 517g Molding cycle: 50s Injection mold cycle: 500,000 times Injection-molded material: PP-T20 Scope of application: Car driver-side knee pad Technical Summary:
Mold manufacturing focuses on the crash-absorbing cushioning performance of the knee guard, the assembly precision of multiple snap-fit features (ensuring tight alignment with the vehicle body and dashboard), and structural strength. It employs an integrated design approach, using 3D modeling to accurately replicate the guard’s complex structures—including reinforcing ribs, mounting snap-fits, and clearance recesses. Simulation tools are leveraged to optimize melt flow and cooling paths, thereby preventing insufficient filling or internal stress-induced cracking during the reinforcement material’s molding process.
Process focus:
Five-axis simultaneous high-speed milling is used to machine the baffle stiffeners, multi-directional snap-fit features, and clearance structures. For areas with uneven baffle wall thickness, the spacing of cooling channels (20–25 mm) and their distance from the cavity surface (10–12 mm) are adjusted accordingly.
Production Highlights:
The mold employs a shrink-fit insert assembly structure. By simply replacing cavity inserts of different specifications, it can accommodate structural variations in knee pads for various vehicle models without requiring replacement of the entire mold set, thereby reducing tooling costs for multi-model production. The inserts are quickly secured via shrink-fit components, boosting disassembly and assembly efficiency by more than 30%.
