1. Mold base: The main frame that supports the mold and is usually heavy.

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

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

4. Triangle locking system or self-locking system: used to ensure that the mold base can maintain stability during operation.

5. Medium plate: Located between the upper and lower molds, it withstands injection pressure and core pulling pressure, while small molds may not have medium plates.

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

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

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

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

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

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

12. Filler: When manufacturing plastic parts, the use of filler types can achieve internal leverage or other structures for molding.

13. Oblique ejector pin: It passes diagonally through the mold for draft operation.

14. Positioning ring and positioning pin: used for positioning and supporting the mold.

15. Nozzles: Used for the melting and injection of plastic into molds in injection molding machines.

16. Internal and external core pulling: Forming internal structures or shells such as holes in the plastic part and detachment from the mold after the product is formed.

17. Contact/sensor: used to detect mold status, such as temperature, pressure, and position.

18. Structural plate: used to support fixed molds and medium-sized plates.

19. Spring: used to strengthen the closing force of the mold and keep the mold closed.

20. Hot runner device: By ensuring the melting and flow of plastic, more and more details and smaller accuracy requirements can be achieved. Generally, it can be removed and used when switching molds.

21. Suction port: When the plastic is compressed on the nozzle, it fully fills the mold cavity.

22. Pneumatic valve/hydraulic valve: The switch function is achieved through electrical control, allowing for suction and injection operations of the mold.

23. Mold temperature control system: used to control the temperature on the surface of the mold and inside the mold cavity to ensure plastic quality, finished product accuracy, and mold life.

24. Cooling channel: capable of quickly transferring heat to the center of the mold and cooling it down.

25. Exhaust device: Avoid defects in the molded object caused by the large amount of gas generated during the injection molding process.

26. Storage hopper: stores plastic particles and is installed below or on the side of the injection molding machine.
