Abstract
The utility model relates to a novel soft packet of towards shell mould of lithium ion battery, include: the jacking device comprises an upper template and a lower template jacking template, and is characterized in that the jacking template is provided with four jacking template shaft sleeves, the lower part of a guide post penetrates through the jacking template shaft sleeves, and the upper template and the jacking template slide along the guide post during operation. The utility model discloses owing to be equipped with the jacking template axle sleeve on jacking template, the lower part of guide post passes the jacking template axle sleeve, and during operation cope match-plate pattern and jacking template slide along the guide post, make whole mould ability non-deformable at work, and the location is more accurate, has guaranteed that the product is stable in quality in continuous production, has improved the bad phenomenon that the outward appearance corrugates, has shortened the long time of jacking template installation and debugging.
Description
Technical Field
The utility model relates to a mould of lithium ion battery production especially relates to a novel soft packet of towards shell mould of lithium ion battery.
Background
At present, in the production process of a polymer lithium ion battery, when an aluminum-plastic film is formed, mold cavities of an upper template and a lower template are not on the same vertical parallel surface, so that the phenomenon of single-side R corner overstretching of a battery shell is easily caused, and the hidden danger that the residual quantity of an aluminum layer at the corner does not reach the standard is caused. The upper and lower templates of the flat template are positioned by four guide posts at present, and the jacking template is not provided with a guide post positioning device, the jacking template is positioned by a shell punching machine table when being positioned, the guide posts are worn and deformed when being used for a long time, the cavity of the upper and lower templates of the shell punching die is not on the same vertical parallel surface when the product is formed, the unilateral gap size of the product is abnormal, the residual quantity of an aluminum layer of the product is influenced, the hidden danger of damage and leakage of the aluminum plastic film is caused, when the product is used for a long time, the template is easy to deform and bend slightly, the pressure is not tight when the aluminum plastic film is formed, and the poor appearance phenomena such as wrinkling are caused.
Disclosure of Invention
The utility model aims at providing a novel soft package of lithium ion battery dashes shell mould to foretell defective design. According to the die, four guide shaft sleeves are added on the jacking template on the basis of an original die, and the guide columns penetrate through the jacking template shaft sleeves, so that the upper template, the lower template and the jacking template are positioned more accurately and are not easy to shift.
The technical scheme of the utility model is that: the utility model provides a novel soft packet of towards shell mould of lithium ion battery, includes: cope match-plate pattern, lower bolster jacking template, the middle part of cope match-plate pattern is equipped with the mould die cavity, goes up the mould in the mould die cavity, and the limit portion of cope match-plate pattern is fixed with four last mould guide bush, and the middle part of lower bolster is equipped with down the model cavity, is equipped with swing joint's lower mould in the lower model cavity, and the limit portion of lower bolster is equipped with four guide posts, and the last mould guide bush of cope match-plate pattern, its characterized in that are passed on the upper portion of guide post: the jacking template is provided with four jacking template shaft sleeves, the lower part of the guide column penetrates through the jacking template shaft sleeves, and the upper template and the jacking template slide along the guide column during working.
The utility model has the advantages that: because the jacking template shaft sleeve is arranged on the jacking template, the lower part of the guide post penetrates through the jacking template shaft sleeve, and the upper template and the jacking template slide along the guide post during working, the whole mould is not easy to deform during working, the positioning is more accurate, the quality stability of products in continuous production is ensured, the bad phenomenon that the appearance wrinkles is improved, and the time for installing and debugging the jacking template is shortened.

Fig. 3 is a perspective view of fig. 2.
Fig. 4 is an exploded perspective view of fig. 3.
Detailed Description
As shown in figure 1, the former mould is because the jacking template does not set up guide post positioner, do not set up the axle sleeve that is used for the guide post direction promptly, the jacking template relies on towards the shell board to fix a position when fixing a position, wear appears and tear to lead to producing between the template and warp for a long time, make and dash shell mould cope and drag template and jacking template not on same parallel surface, lead to the unilateral clearance size of product unusual, influence the product aluminium lamination residual quantity, the template slightly warp the buckling appears easily, it is not tight to press when causing the plastic-aluminum membrane shaping, the bad phenomenon of outward appearance such as corrugating appears.
As shown in fig. 2 to 4, the present invention includes: cope match- plate pattern 1, 2 jacking templates 3 of lower bolster, the middle part of cope match-plate pattern is equipped with mould die cavity 11, it is equipped with last mould in the mould die cavity to go up the mould, the limit portion of cope match-plate pattern is fixed with four last mould guide shaft sleeves 12, the middle part of lower bolster is equipped with lower mould cavity 21, be equipped with swing joint's lower mould 5 in the lower mould cavity, the limit portion of lower bolster is equipped with four guide posts 4, the last mould guide shaft sleeve 12 of cope match-plate pattern is passed on the upper portion of guide post, jacking templates 3 is equipped with four jacking template axle sleeves 6, the lower part of guide post passes the jacking template axle sleeve, during operation cope match-plate pattern and jacking template slide along the guide post. Because the upper template, the lower template and the jacking template are positioned and oriented by the four guide posts, the die works stably, is not easy to deform and shift even if being used for a long time, and can always keep the templates in the same plane in the processes of disassembling, assembling, forming products and the like.
In addition, the resistance to deformation can be further improved by thickening the templates on the basis of the above.
