EspañolPlastic injection molding is a manufacturing process used to produce a variety of plastic products. The process involves the use of a plastic injection mold, which is a complex tool made of multiple parts. Here is a breakdown of the composition and structure of a typical plastic injection mold:
Mold base: The mold base is the foundation of the mold and holds all the other components in place. It is typically made of hardened steel and provides stability and strength to the mold.
Core and cavity inserts: The core and cavity inserts are the parts of the mold that create the shape of the final product. The core forms the interior of the product, while the cavity forms the exterior. These inserts are usually made of hardened steel and are precision-machined to create a high-quality finished product.
Runner system: The runner system is the network of channels and gates that allow the molten plastic to flow into the mold cavity. The runner system is designed to ensure that the plastic fills the cavity completely and evenly, without any air bubbles or voids.
Ejector system: The ejector system is responsible for removing the finished product from the mold once it has cooled and solidified. The ejector system typically consists of pins, plates, and rods that push the product out of the mold.
Cooling system: The cooling system is designed to control the temperature of the mold during the injection molding process. It is typically made up of water channels or tubes that circulate coolant through the mold to prevent overheating and ensure consistent cooling of the plastic.
Mold base plates: Mold base plates are the top and bottom plates of the mold base that hold the core and cavity inserts in place. These plates are usually made of hardened steel and provide a smooth surface for the plastic to be injected into.
