Shape is corresponding.
On the basis of technique scheme, between end face and the end face of described core rod body of described protuberance
Distance be 1～3mm.
On the basis of technique scheme, the length of described protuberance is less than described core rod body length
Half.
On the basis of technique scheme, a length of the 3 of described protuberance～30mm, width be 3～
45mm。
On the basis of technique scheme, the cross sectional shape of described protuberance is that triangle is circular or square
Shape.
From above technical scheme, the structure of putamina punching mould is improved by this utility model, at mould
One protuberance laterally highlighted is set on core so that the putamina obtained after stamp increases by one on putamina air bag limit
Individual convex hole, this is the forced position of twists and turns in the convex hole transferable battery core circular flow on air bag limit, thus turns
Move the crooked place that stress is concentrated, it is to avoid chink occurs bottom battery core air bag limit, deducts at the bottom of the pressure of air bag limit simultaneously
Angular motion solves air bag limit circular flow chink and the problem of position, angle bending breakage, effectively prevents two envelope edge sealing
Wrinkling, can use manpower and material resources sparingly, reduce battery core and scrap.

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in more detail.
Detailed description of the invention
As it is shown in figure 1, putamina punching mould of the present utility model includes lower bolster 1, cope match-plate pattern 2, middle mold
Plate 3 and core rod 4.Guide pillar 5 it is provided with, in the position, four angles of lower bolster 1 in the present embodiment on lower bolster 1
Put and each a guide pillar 5 is set.Position corresponding with guide pillar 5 on cope match-plate pattern 2 is provided with guide pin bushing 6, leads
Set 6 is enclosed within guide pillar 5, and cope match-plate pattern 2 can be along leading under the control controlling element as mobile in cylinder, motor etc.
Post 5 moves up and down.Middle template 3 is arranged on lower bolster 1, and middle template 3 is by being arranged on lower bolster 1
Spring 7 supports, it is preferred that be additionally provided with contour screw 8 on lower bolster 1, template 3 in controlling
Move down the limit.Core rod 4 is arranged on lower bolster 1.Middle template 3 offers the groove passed for core rod 4
3a, cope match-plate pattern 2 offers the mould hole 2a, groove 3a passed for core rod 4 top and the shape of mould hole 2a
Corresponding with the cross sectional shape of core rod 4.
Shown in as shown in Figure 2, Figure 3 and Figure 4, core rod 4 of the present utility model includes core rod body 4a and protuberance
4b, protuberance 4b are arranged at the top of core rod body 4a, and protrude from core rod body 4a side.In order to
It is easy to describe, the surface that core rod body 4a contacts with lower bolster 1 is defined as bottom surface, relative with bottom surface
Surface be defined as end face.Protuberance 4b extends prominent along the one side of core rod body 4a, the present embodiment
The cross sectional shape of protuberance 4b is triangle, between end face and the end face of core rod body 4a of protuberance 4b
Distance d1 be 1～3mm, length d2 of protuberance 4b is 3～30mm, the width d3 of protuberance 4b
It is 3～45mm.Length d2 of protuberance 4b less than the half of core rod body 4a length d, i.e. d2≤
d/2.Preferably, the prominent top of protuberance 4b is circular arc.Additionally, the cross sectional shape of protuberance also may be used
Think circular or square etc..
Below the work process of this utility model putamina punching mould is further described:
When putamina is carried out stamp, be positioned over by aluminum plastic film in middle template 3, i.e. aluminum plastic film is positioned at middle mold
Between plate 3 and cope match-plate pattern 2, cope match-plate pattern 2 under the mobile control controlling element along guide pillar 5 to moving down
Dynamic, and be depressed in middle template 3, middle template 3 cope match-plate pattern 2 pressure effect next rise and move down, until
The top of the bottom surface of middle template 3 and contour screw 8 is supported, and middle template 3 stops mobile, the top of core rod 4
In the groove in middle template 3, the mould hole stretched on cope match-plate pattern 2, thus by the plastic-aluminum in middle template 3
Film heads in the mould hole 2a of cope match-plate pattern 2, forms putamina, and due to core rod 4, to have one outside along its one side
Prominent protuberance 4b, therefore, aluminum plastic film 10 edge of the putamina 9 gone out has outwardly
Convex hole 9a (Fig. 5).
Putamina owing to going out has a convex hole at its edge, after lithium battery encapsulation, and the electricity that putamina is formed
Little convex hole, core air bag limit can avoid battery core air bag limit to occur wedge angle at cavity, the bending that stress transfer is concentrated
Position, it is to avoid position, angle bending breakage, can reduce and encapsulate to two envelopes, thus solve air bag limit because of bending
The problem causing chink, it is to avoid battery core is scrapped, improves yields.
Preferably, in previous embodiment, the incline of core rod protuberance need to be polished slope, in case edge sealing is wrinkling,
Additionally, the big I of protuberance adjusts according to putamina size shape, play edge sealing wrinkle resistant and air bag can be shifted
Position, bending place, limit, makes folding s tress not at housing bottom；The size of core rod protuberance is according to putamina
Cheat deep and length and width size and the shoulder height with core rod upper surface is designed.
The above, be only preferred embodiment of the present utility model, not does this utility model any
