What Are Activated Cores On A Injection Molding Mold

Activated cores in injection molding refer to components within the mold that can move or be manipulated during the molding process to form complex features on the molded part. These cores are often used to create undercuts, holes, threads, or other intricate shapes that cannot be formed using a simple two-part mold.

Here are some key aspects of activated cores:

  1. Functionality: Activated cores move in and out of the mold cavity to shape the interior or complex features of the molded part. They can be activated mechanically, hydraulically, or pneumatically.
  2. Types of Activated Cores:
    • Side Cores: These are used to create features on the side of the part. They move horizontally into the mold cavity and retract to release the part.
    • Unscrewing Cores: These are used to form internal or external threads on a part. They rotate to unscrew from the part after molding.
    • Collapsible Cores: These are used to create complex internal features and can collapse inward to be removed from the molded part.
  3. Activation Mechanisms:
    • Mechanical Activation: Uses cams, levers, or gears within the mold to move the core.
    • Hydraulic Activation: Uses hydraulic cylinders to move the core. This method is precise and can handle large forces.
    • Pneumatic Activation: Uses air pressure to move the core, suitable for smaller forces and faster movements.
  4. Applications:
    • Creating internal threads or features that cannot be formed with a straight-pull mold.
    • Forming undercuts or side holes that require side action.
    • Producing complex geometries that require collapsible or rotating elements.
  5. Design Considerations:
    • Cycle Time: The activation and movement of cores can affect the overall cycle time of the molding process.
    • Complexity: The design and integration of activated cores add complexity to the mold design and construction.
    • Maintenance: Activated cores can require more maintenance due to the additional moving parts and mechanisms.

Activated cores enhance the versatility and capability of injection molding processes, enabling the production of complex and detailed parts that would otherwise be difficult or impossible to mold with traditional fixed molds.
