The driving component is arranged below the lower ejection rod 22, and when the lower ejection is needed, the driving component pushes the lower ejection rod 22 to ascend so as to eject the workpiece.
The guide sleeve 21 is the same as the existing first guide sleeve 11 and second guide sleeve 13 in terms of action and manufacturing materials, and plays roles of guiding and limiting the lifting of the lower ejector rod 22, so that the moving accuracy of the lower ejector rod 22 is improved. The lower ejector pin 22 and the guide sleeve 21 slide up and down with clearance fit.
In order to prevent abrasion, a rubber sleeve can be arranged between the lower ejector rod 22 and the inner wall of the guide sleeve 21. Meanwhile, the guide sleeve 21 is a copper sleeve to ensure the strength and the high temperature resistance.
