Common Ejection Components in Injection Molds
Ejection components are critical in injection molds, primarily responsible for expelling molded plastic parts from the mold cavity.
Push Pin
Function: Directly contacts and pushes the part to separate it from the cavity.
Characteristics: Simple structure, widely used.
Push Plate
Function: Ejects multiple or larger parts simultaneously.
Characteristics: High rigidity, strong load-bearing capacity.
Push Rod
Function: Transmits the pushing force from the push plate or pin to the part.
Characteristics: Can transmit large pushing forces.
Oblique Core
Function: Used to eject parts with side walls or recesses.
Characteristics: Complex structure but capable of complex ejection movements.
Slide Core Mechanism
Function: Used to eject parts with internal holes or recesses.
Characteristics: Complex structure, various movements.
Spring
Function: Provides pushing force to return the ejection components to their original position.
Ejection components are indispensable in injection molds, and their selection and design directly affect the quality and production efficiency of plastic parts. By carefully selecting and designing ejection components, it is possible to improve product quality and reduce production costs effectively.
