Injection mold assembly refers to the process of assembling the different parts of an injection mold, which is used to produce plastic parts through injection molding. The main structure of an injection mold assembly typically consists of the following parts:
Mold Base: The mold base is the main structure of the injection mold assembly, which provides support and stability for the mold. It is typically made of steel and contains various cavities and components necessary for the molding process.
Core and Cavity: The core and cavity are the two main components of the mold that create the shape of the plastic part. The core is the internal component that creates the inner shape of the part, while the cavity is the external component that creates the outer shape of the part.
Ejector Pins: Ejector pins are used to remove the molded part from the mold after the molding process is complete. They are typically located in the mold base and are designed to push the part out of the mold when activated.
Sprue Bushing: The sprue bushing is located at the top of the mold and connects the injection molding machine to the mold. It is designed to direct the molten plastic into the mold cavity.
Cooling System: The cooling system is used to cool the mold after the plastic has been injected into the mold cavity. It typically consists of water channels or pipes that are located throughout the mold to dissipate heat and cool the plastic part.
Guide Pins and Bushings: Guide pins and bushings are used to align the two halves of the mold during assembly and to ensure proper alignment during the molding process.
Overall, the main structure of an injection mold assembly is designed to create the shape of the plastic part and to facilitate the injection molding process, while providing support, stability, and cooling for the mold.
