Contacting surface product is big, and the stress of spacing ring is visibly homogeneous, can be with the visibly homogeneous support for realizing the collar, it is to avoid spacing ring local pressure
It is too high and cause spacing ring to damage.
Preferably, the outer peripheral face of the collar is provided with the bulge loop contacted with the inwall of counter sink, the bulge loop is set
In the bottom of the collar.
By using above-mentioned technical proposal：Bulge loop is set, is the interior of bulge loop and counter sink when in collar insertion counter sink
Wall is contacted, and can so reduce the contact area of the collar and counter sink, further to reduce scattering and disappearing for heat.Also, in injection
When, only bulge loop is contacted with counter sink, can reduce the abrasion of the collar, it is to avoid occur what is fallen down after the collar weares and teares in counter sink
Chip.
Preferably, the junction of the spacing ring and nozzle body is provided with chamfering structure.
By using above-mentioned technical proposal：Chamfering structure is set, spacing ring and the junction of nozzle body can be avoided to answer
Power concentration phenomenon, it is ensured that the structural strength of spacing ring.
Preferably, the elastomeric pad is several, set along the length direction array of nozzle body.
By using above-mentioned technical proposal：Multiple elastomeric pads are set, preferably support on the one hand can be played and slow
Rush effect；On the other hand, elastomeric pad can play guide effect to the sliding of nozzle body, it is to avoid nozzle when being slid in the collar
Existing shift phenomenon.
Preferably, being provided with deep gouge around nozzle body on the face that the collar is contacted with elastomeric pad, the deep gouge is in a ring
Set, the internal diameter of the deep gouge is equal with the external diameter of nozzle body, the external diameter of the deep gouge is less than the external diameter of elastomeric pad.
By using above-mentioned technical proposal：Deep gouge is set, and the scope of activities in vertical direction of elastomeric pad can be obtained
Increase, the elastic force of elastomeric pad can also be stretched, and can improve the support effect of elastomeric pad, play preferably buffering effect
Really.
