What are the Main Parts of Injection Mold Components

The injection mold components mainly include the following parts:

1. Fixed plate and dynamic plate: located on the upper and lower ends of the mold base respectively, used to fix the lower and upper molds, and equipped with corresponding guiding mechanisms.

2. Hardness adjustment gasket: used to adjust the gap and hardness of the mold.

3. Triangle locking system or self-locking system: used to ensure that the mold frame can remain stable during operation.

4. Medium size plate: located between the upper and lower molds, it bears injection pressure and core pulling pressure, and small molds may not have medium size plates.

5. Upper mold: also known as dynamic mold, it moves to allow plastic products to detach from the mold.

6. Lower mold: also known as fixed mold, it remains unchanged and serves as the fundamental foundation for injection molding.

7. Pushing needle: used to push formed objects out of the mold.

8. Guide post: used to limit the distance when the mold is closed, while providing both horizontal and vertical guidance.

9. Guide sleeve: installed on the guide pillar to reduce friction between the guide pillar and the mold.

10. Mold cavity: used for plastic filling and forming plastic products during the injection molding process.

11. Core filling: When manufacturing plastic parts, the use of core filling types can achieve internal leverage or other structures for molding.

In addition, there are components such as the sprue (sprue sleeve), positioning ring (ring), template, top pin protection switch, top rod hole, and water outlet rod, which also play a crucial role in the operation of the mold.
