After some plastic parts are formed, they cannot fall off automatically due to the shape, but remain in the mold cavity. This requires a device to push the plastic parts out of the mold cavity to facilitate the removal of the plastic parts.
This device is called a ejector
After injection molding, the product needs to be demoulded out. If there is no ejection system, the product cannot be completely removed.
The ejection mode includes inclined ejection, ejection of ejector pin and core pulling of oil cylinder
