Side knife；
The middle part of the material pressing core is equipped with separation punch retainer, and the punch retainer is equipped with punch-pin hole, institute
Punch-pin hole is corresponded on the lower end surface for the upper mold stated and is fixed with separation punch-pin, and the separation punch-pin can pass through from punch-pin hole
And it stretches out；The supplement material that the separation punch-pin is used to connect among two parts is cut off, and keeps two parts completely separable.
The upper surface of the material pressing core is equipped with spring transition block, and the lower end surface of the upper mold is equipped with nitrogen gas spring,
The upper end of the nitrogen gas spring is fixed in upper mold, and lower end is fixed in spring transition block；
Corresponding material pressing core is equipped with binder seat, the corresponding separation in the middle part of the binder seat in the middle part of the upper surface of the lower die
Punch-pin is equipped with punch-pin hole receiving hole.
The side of the upper mold lower end surface is equipped with self-oiling guide bushing；Self-oiling guide bushing is corresponded on the side of the lower die to set
There is guide post.
The combination of the self-oiling guide bushing and guide post is equipped with two groups, is located at the two sides of upper die and lower die.
The material pressing core is that arc-shaped notch is equipped in the middle part of trapezoidal, trapezoidal bottom edge.
The spring transition block be equipped with it is multiple, be distributed in around punch retainer, the nitrogen gas spring also is provided with
Multiple groups are corresponded with spring transition block.
The edge of the binder seat is equipped at intervals with multiple waste material cutter blocks.
The invention has the benefit that
On the one hand the present invention touches in upper mold by the spring transition block of setting nitrogen gas spring and its cooperation and is placed in lower die
On material when, give pressure in advance, positioning needs the material suppressed, and guarantees the precision and stability of material compacting, guarantees pressure
Part quality, while guaranteeing upper mold when leaving lower die, give part downward thrust, guarantee part is in automatic demoulding, always
It is placed in lower die.
The present invention can effectively ensure that the stability-of-path of upper and lower mould molding by self-oiling guide bushing and guide post, improve compacting essence
Degree.
