Plastic sleeve separation die of reverser

The invention discloses a plastic sleeve separation die of a reverser. The separation die comprises a movable upper die and a fixed lower die, and is characterized in that an ejection pin is arranged at the bottom of the movable upper die; the diameter of the ejection pin head is smaller than the diameter of an inner hole of the plastic sleeve; the fixed lower die comprises an upper pad and a lower pad which are fixedly connected; an upper through hole through which a combined body of the reverser and the plastic sleeve can penetrate is formed in the upper pad; the diameter of the upper through hole is greater than the excircle diameter of the plastic sleeve; a lower through hole through which the reverser can penetrate independently is formed in the lower pad; the diameter of the lower through hole is greater than that of the excircle of the reverser and is smaller than that of the excircle of the plastic sleeve. The plastic sleeve separation die is specially used for separating the reverser and the plastic
