Description
Technical field
This utility model is related to negative angle one-shot forming stamping mold in a kind of mould, belongs to the shaping in mechanical engineering and mould
Technical field.
Background technology
With the development of China's punching press industry technology, people the aesthetics of stamping products, precision are had it is higher will
Ask, also more and more occur in that bending negative angle is present in product.In existing production, several works being adopted bending negative angle technology more
Position repeatedly molding realizing.
Realized using the multiple molding of several stations, such design often has dismounting inconvenience, maintenance cost height etc. and lacks
Point.In addition, the premise of negative angle bending be must in a upper station by shape of product be bent into no more than 90 ° it is curved, so tie
Structure ability normal work, otherwise, current scheme then can not be completed less than 90 ° of bendings.Station is more in same mold, into
This is higher, and maintenance is also more difficult, and how to improve disadvantages mentioned above, and the disposable bending and molding of negative angle is realized in one set of die just
Become the technical problem of the emphasis for being badly in need of solving in industry.
In addition publication number is the utility model patent of CN202861142U, discloses a kind of rushing for bending negative angle formation
Compression mould, but, the mould is only processed into negative angle to right angle part, and flat plate stock is processed into into negative angle needs multistep to realize, exists
Certain limitation.
Utility model content
In order to overcome the shortcoming of prior art, the quantity of mould inside station is reduced, save die space, mould is carried out
Modularized design, makes the impaired replacement that is more easy to, this utility model provide negative angle disposal molding stamping mold in mould.
Technical solutions of the utility model are as follows：
Negative angle one-shot forming stamping mold in mould, including upper bolster and die shoe, below the upper bolster pad is provided with
Plate, is provided with fixed plate below the upper padding plate, lower bolster is provided with above the die shoe, is provided with below the upper padding plate
Drift, the lower right corner of the drift is provided with punch edge, and the lower portion of ram is provided with the groove of circular arc, on the punch edge
The projection of circular arc is provided with, the groove and raised size are adapted, and the punch edge carries out one centered on center of arc
Determine the rotary moveable of angle, slide block is provided with above the lower bolster, the left end of the slide block is provided with fixed insert, the slide block
Right-hand member be provided with take-up housing.
As preferred, it is connected by the track of domatic between the slide block and take-up housing, the slide block can be along track
Carry out the motion of diagonal upward direction.
Used as preferred, the upper bolster is provided with push rod, and the push rod passes through drift, the bottom of the push rod and drift
Insert contacts.
Used as preferred, the left end of the drift is provided with drift block, and the die shoe is provided with drift by knife, described to lean on
The right-hand member of knife is provided with by knife insert.
This utility model beneficial effect is：It is equal with by knife easy-wearing surface with product contact surface, drift to drift and slide block
Insert is added, because drift and punch edge part arc chord angle are designed, punch edge can freely swing, so as to product negative angle one
Secondary molding, the left end of the drift is provided with drift block, and the die shoe is provided with drift by knife, and the right-hand member by knife is provided with
By knife insert, drift block is used for fixing drift, prevents drift from shifting；Drift is used for reducing side during from the beginning bending and molding by knife
Xiang Li, it is ensured that the accuracy of bending, by knife insert with use cooperatively from head rest knife, primarily to be conveniently adjusted aborning or
There is abrasion in person, can quick-replaceable after damage.
Mould inner slide adopts modularized design so that easily the position of abrasion can be changed at any time, which greatly enhances mould
The bulk life time of tool, and be readily disassembled, maintain easily, and mould compact conformation itself is simple, saves die space, dismounts
It is convenient, it is easy to de- material.

Specific embodiment
This utility model is described in further detail below in conjunction with the accompanying drawings.
Refering to Fig. 1 to Fig. 2.
Negative angle one-shot forming stamping mold in mould, including upper bolster 10 and die shoe 15, the lower section of the upper bolster 10 sets
The lower section for having upper padding plate 11, the upper padding plate 11 is provided with fixed plate 12, and the top of the die shoe 15 is provided with lower bolster 14, described
The lower section of upper padding plate 11 is provided with drift 1, and the lower right corner of the drift 1 is provided with punch edge 2, and the bottom of the drift 1 is provided with circular arc
The groove of shape, the punch edge 2 is provided with the projection of circular arc, and the groove and raised size think adaptation, the drift edge
Block 2 carries out the rotary moveable of certain angle centered on center of arc, and the top of the lower bolster 14 is provided with slide block 4, the cunning
The left end of block 4 is provided with fixed insert 3, and the right-hand member of the slide block 4 is provided with take-up housing 5.
It is connected by the track 16 of domatic between the slide block 4 and take-up housing 5, the slide block 4 can be carried out along track 16
The motion of diagonal upward direction.
The upper bolster 10 is provided with push rod 6, and the push rod 6 passes through drift 1, bottom and the punch edge 2 of the push rod 6
Contact.
The left end of the drift 1 is provided with drift block 7, and the die shoe 15 is provided with drift by knife 8, described by knife 8
Right-hand member is provided with by knife insert 9.
This utility model principle is：When mould carries out matched moulds, punch edge 2 is contacted with product 13, downwards work, then
Contact slipper insert 3, continues work downwards, and now punch edge 2 does work simultaneously with slide block 4, the negative angle of the lower section of punch edge 2
Cleverly will promote product 13, so as to by formed product be negative angle.When mould is molded, slide block 4 is due to the work of lower section spring force
With upward sliding, the in type negative angle of product is avoided, now, the push rod 6 above drift is started working, promotes punch edge 2,
Because the recess of drift 1 and the ledge of punch edge 2 are both designed as arc chord angle, so punch edge 2 can be perfect with drift 1
It is chimeric and can activity freely, when the stress of punch edge 2 is in push rod 6, punch edge 2 along circular arc angular oscillatory motion, so as to complete de- material.
Above-mentioned drawings and Examples are merely to illustrate this utility model, and any art those of ordinary skill is to it
The appropriate change done or modification, or use other flower pattern instead and make this technical change, all should be regarded as new without departing from this practicality
Type patent category.
