The Ejection System of the molding machine is used to eject the formed parts from the mold. This system is usually executed after the mold is closed to ensure that the finished product can quickly and accurately detach from the mold. Here are some common ejection systems:
Jet ejection: This system uses high-pressure air to be sprayed into the mold, ejecting the formed parts from the mold. Jet ejection typically has a fast speed and is suitable for applications that do not require high surface quality of parts.
Mechanical ejection: The mechanical ejection system uses mechanical components such as push rods, springs, or cylinders to push parts out of the mold. This method can provide greater control and is suitable for applications with high surface requirements for parts.
Hydraulic Ejection: The hydraulic ejection system uses hydraulic cylinders to push parts out of the mold. This system provides significant propulsion and is suitable for the ejection of large or complex parts.
Stripper Plate: Sometimes, there is a transverse plate in the mold that pushes the parts out of the mold through mechanical or hydraulic pressure. This design is suitable for some special shaped parts.
Ejector Pin: Ejector pin is a common ejection device that uses mechanical or hydraulic pressure to extend out of the mold and push out parts. The ejector pin is usually located on one side or bottom of the mold.
Ejector Sleeve: An extruder is a cylindrical device fixed in a mold that extends and pushes parts out of the mold through mechanical or hydraulic pressure.
Magnetic ejection: Some special applications may use magnetic force to push parts, controlling the speed of ejection by adjusting the force of the magnetic field.
