Description
Technical field
The utility model is related to Electronic Packaging production technical field, more particularly to a kind of ballistic resistant sheet lead frame stamping die.
Background technology
With the development of science and technology high-power electronic product demand increasingly increases, market is more and more to lead frame demand.
Because product density is higher, than relatively thin, the number of times of punching press compares tablet existing SMA chips lead frame above same flake products
Many, the pressure that tablet bears in itself is big, and the influence that tablet can be stressed in itself produces deformation by a small margin, causes tablet certainly
Body uneven surface, serious meeting causes deformation, is damaged product appearance, and the follow-up of influence product uses；Additionally, deformation of products is led
Cause punching production stability not enough, product shell fragment phenomenon easily occurs, causes product fraction defective to steeply rise.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of deformation small, the reliable and stable ballistic resistant sheet lead of punching press
Framework stamping die.
The utility model solves the technical scheme that its technical problem used：The ballistic resistant sheet lead frame stamping die bag
Include bed die and pressing mold with shaping area, the shaping area includes spaced shaping area I arranged side by side and shaping area II, it is described into
Middle part between type area I and shaping area II is provided with ballistic resistant sheet punch die, and the ballistic resistant sheet punch die includes the salient point located at the pressing mold
Pad and the relative groove cushion block located at the bed die matched with the salient point pad.
In a kind of preferred embodiment of the ballistic resistant sheet lead frame stamping die that the utility model is provided, the ballistic resistant sheet punching
The quantity of mould is multiple, is vertically distributed along Y-axis.
The utility model provide ballistic resistant sheet lead frame stamping die a kind of preferred embodiment in, two ends it is described convex
The length of the length less than the salient point pad at middle part of point pad.
In a kind of preferred embodiment of the ballistic resistant sheet lead frame stamping die that the utility model is provided, the salient point pad
Cross section fall the fillet of R0.1mm for the round end of bonding of 0.4X0.3mm, and corner.
In a kind of preferred embodiment of the ballistic resistant sheet lead frame stamping die that the utility model is provided, the salient point pad
Width less than the groove cushion block width.
In a kind of preferred embodiment of the ballistic resistant sheet lead frame stamping die that the utility model is provided, the groove cushion block
Depth more than the salient point pad protrusion length.
In a kind of preferred embodiment of the ballistic resistant sheet lead frame stamping die that the utility model is provided, the groove cushion block
Fall the fillet of R0.1mm for the corner at top.
Compared with prior art, the beneficial effect of the ballistic resistant sheet lead frame stamping die that the utility model is provided is：This reality
The ballistic resistant sheet punch die is set with the new middle part by between the shaping area I and shaping area II, using the ballistic resistant sheet
Punch die increases by one groove between two stamping forming products, makes the center section shrinkage in width of product, balances out due to punching
Product is expanded outwardly caused by compression, product is kept certain flatness, substantially increases the qualification rate of product, is improved
Production efficiency.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme in the utility model embodiment, below will be to needed for embodiment description
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：
Fig. 1 is the structural representation of the ballistic resistant sheet lead frame stamping die that the utility model is provided；
Fig. 2 is that the partial enlargement that Fig. 1 is provided implements structure chart；
Fig. 3 is the partial structural diagram of SMA chip lead frames.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment for being obtained, belongs to the scope of the utility model protection.
Also referring to Fig. 1 and Fig. 2, the ballistic resistant sheet lead frame stamping die 1 includes the bed die 12 with shaping area 11
With pressing mold 13, the shaping area 11 includes the 11a of the spaced shaping area I and 11b of shaping area II, the 11a of the shaping area I arranged side by side
And the middle part between the 11b of shaping area II is provided with ballistic resistant sheet punch die 14, the ballistic resistant sheet punch die 14 is included located at the pressing mold 13
Salient point pad 142 and the relative groove cushion block 143 located at the bed die 12 matched with the salient point pad 142.
Preferably, the quantity of the ballistic resistant sheet punch die 14 is multiple, is vertically distributed along Y-axis, and the salient point at two ends is served as a contrast
Length of the length of block 142 less than the salient point pad 142 at middle part.
