Mould Structure & Design Description

The mould core plate serves as the primary mounting and positioning base for core inserts and core pins within the injection mold. Its design focuses on flatness, rigidity, and precise hole positioning to ensure correct cavity alignment. Structural considerations include load distribution, thermal deformation control, and ease of maintenance for complex or multi-cavity mold assemblies.
