Abstract
The utility model discloses a mould once compounds, including the C mould, the corresponding department in C mould top is equipped with stamping core on the C mould, and the C mould includes centre form and compound external mold once, and the external mold that once compounds cup joints and become combination formula lower mould on the centre form. The external mold that once compounds is cylindricly, and once the compound external mold bottom outside is equipped with the bulge loop, the bottom inboard is provided with expansion port, and once compound external mold inside of the top of is provided with the inclined snap ring that inwards heels. The centre form is cylindricly, and the centre form bottom outside is equipped with the centre form bulge loop, inside of the top of is provided with the inclined centre form snap ring that inwards heels. The centre form bulge loop external diameter of centre form is greater than once compound external mold internal diameter and is less than the bulge loop external diameter. It is fast to have the shaping, the more delicate characteristics of size control.
Description
Technical field
The utility model belongs to technical field of mold, especially once-combined mould.
Background technology
What production battery steel shell was used at present is all gradual continuous common die, and straight up and down, mould punching is single, only
Common straight wall box hat can be produced, the box hat limitation of production is big, and wall thickness causes box hat capacity small, it is impossible to meet existing great Rong
Measure the basic demand of lithium battery steel shell.
Utility model content
The utility model is intended to overcome the defect of prior art, there is provided a kind of once-combined mould, fast with shaping, size
Control it is more accurate and can the disposable novel steel-shelled of punching different wall advantage.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of once-combined mould, including C moulds, C moulds top corresponding section are provided with C mould upper punch cores, and C moulds include
Internal model and once-combined external mold, once-combined external mold is socketed in turns into mould under combined type in internal model, once-combined external mold is in cylinder
Shape, once-combined external mold bottom outside is provided with bulge loop, bottom inside and is provided with extension mouth, and once-combined outer mold top inner side is set
The oriented inclined snap ring in inner side, internal model is cylindrical, and internal model bottom outside is provided with internal model bulge loop, inside top and is provided with to inner side
Inclined internal model snap ring, the internal model bulge loop external diameter of internal model is more than once-combined external mold internal diameter and less than bulge loop external diameter.
Compared with prior art, the utility model has following beneficial effect：
The common die innovation of script is Novel combination mold by this set technology, is had the advantage that：Shaping is fast, and size Control is more
It is accurate and can disposable punching different wall novel steel-shelled.Citing：Script common die can only produce 0.25mm wall thickness
Box hat, straight up and down, NEW TYPE OF COMPOSITE mould can produce 0.25mm and 0.15mm wall thickness two kinds of different walls be embodied in it is same
On box hat.Further by the thinning of wall thickness, volume is produced greatly, the big New Type of Differential thicker box hat of capacity meets present day
The gradually demand condition of the high-capacity lithium battery of demand.
Brief description of the drawings
Fig. 1 is the schematic diagram of the once-combined mould of the utility model.
Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in figure 1, a kind of once-combined mould, including C moulds 1, C moulds top corresponding section is provided with C mould upper punch
Core 2, C moulds include internal model 11 and once-combined external mold 12, and once-combined external mold 12 is socketed in internal model 11 to be turned under combined type
Mould.Once-combined external mold is cylindrical, and once-combined external mold bottom outside is provided with bulge loop, bottom inside and is provided with extension mouth, one
Secondary compound external mold inside top is provided with the inclined snap ring in inside side.Internal model is cylindrical, and it is convex that internal model bottom outside is provided with internal model
Ring, inside top are provided with the inclined internal model snap ring in inside side.The internal model bulge loop external diameter of internal model is more than once-combined external mold internal diameter
And less than bulge loop external diameter.
Operation principle：It is mould under combined type by mould innovation under originally single integral type using lower mould composite structure, leads to
The combination of the mold of mould 2 is crossed down, during punching box hat, upper punch core is disposable by two sections of assembling die by steel band
Stretching, and die assembly cooperation, successfully by moulding steel casing for two sections different wall novel lithium battery box hat.
Explanation implementation method of the present utility model is the foregoing is only, the utility model is not limited to, for ability
It is all within spirit of the present utility model and principle for the technical staff in domain, any modification, equivalent substitution and improvements made
Deng should be included within protection domain of the present utility model.
