Technical Field

The invention relates to the technical field of lithium ion batteries, in particular to a stamping die for an aluminum plastic film of a lithium ion battery.

Background

At present, an aluminum plastic film forming core part … -die in the production process of the polymer soft package lithium ion battery is mostly a single-piece die which is separated from top to bottom, the single-piece die has high requirements on adjustment of the parallelism of a template, is not easy to adjust, and is easy to stretch the surface of the aluminum plastic film in the forming process, so that the production cost is increased.

The single-chip die is only divided into an upper die plate, a lower die plate and a die core, wherein the die core is directly placed in a female die cavity of the lower die plate and is in clearance fit, and the die core cannot be locked and fixed at one time, so that the die core is displaced on one side in the aluminum plastic film forming process, the thickness of an R angle after forming cannot be controlled, and the phenomenon of single-side extrusion bursting of a punched film shell is easy to occur.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides the stamping die for the lithium ion battery aluminum plastic film, which is simple in structure, convenient to operate and practical.

The invention is realized by the following modes:

the utility model provides a stamping die of lithium ion battery plastic-aluminum membrane which characterized in that: the die comprises an upper die holder and a lower die holder, wherein the upper die holder is connected with an upper template through a bolt; the middle part of the upper template is provided with a convex die cavity; an aluminum plastic film male die is arranged in the male die cavity; the upper template is provided with a guide post;

a mold core bottom plate is arranged on the lower mold base; the mold core bottom plate is connected with a middle mold plate; the middle template is positioned right below the upper template; a concave die cavity is arranged in the middle of the middle template; an aluminum plastic film female die is arranged in the female die cavity; the aluminum-plastic film female die is positioned right below the aluminum-plastic film male die; the middle template is provided with a guide sleeve matched with the guide post;

the lower die base, the die core bottom plate and the middle die plate are connected through parallel guide pillars; a spring is arranged between the middle template and the mold core bottom plate;

and the lower die base is connected with an ejector rod, and the upper end of the ejector rod sequentially penetrates through the die core bottom plate and the middle die plate and is positioned in the cavity of the female die.

Furthermore, the upper die plate and the middle die plate are respectively provided with an oil nozzle which is respectively communicated with the guide column and the guide sleeve.

The invention has the beneficial effects that: the integral type structure facilitates the use, enables horizontal cooperation between the cope and drag template, but the clearance management and control between mold core and the die cavity to reach and guarantee that shaping back membrane shell R angle thickness reaches relatively unanimity.
