Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of wear-resisting type stamping die discharging mandril, including bottom plate 6, the upper surface middle position of bottom plate 6
Place is welded with mandril ontology 3, and the lateral wall of mandril ontology 3 is arranged with protective sleeve 4, and the inner volume diameter of protective sleeve 4 is big
Small equal in magnitude with the diameter of section of mandril ontology 3, mandril ontology 3 and protective sleeve 4 are solid by ejection cap 1 and standing screw 10
Fixed connection, so that push rod structure install compact, increases stability when mandril movement.
The outer surface of protective sleeve 4 is inlaid with multiple balls 5, and multiple balls 5 are equally divided into four groups and inlay peace in crosswise
Mounted in the lateral wall of protective sleeve 4, and four groups of balls 5 are installed perpendicular to bottom plate 6, protect mandril ontology 3 by protective sleeve 4
