Components of Injection Mold Tooling
Mold Base: The foundation of the mold, typically made from steel or aluminum, provides stability and houses other components.
Cavity and Core: The cavity is the hollow space that defines the outer shape of the part, while the core forms the inner shape. These are precisely machined to ensure accuracy.
Ejector System: This system helps push the finished part out of the mold once it has cooled and solidified. It often includes ejector pins, plates, and springs.
Cooling Channels: Integrated into the mold, these channels allow for efficient cooling of the molten material, reducing cycle times and improving part quality.
Runner System: This network of channels directs the flow of molten plastic from the injection nozzle to the mold cavities.
Gate: The point at which the molten material enters the mold. The design of the gate can significantly impact flow characteristics and part quality.
