In a specific embodiment, a kind of molding die with Self-locking angle bearing surface is present embodiments provided, specifically
, which includes upper trimming die, lower die holder 5 and lower die 4.
The upper punch 8 of wherein upper trimming die is matched with lower die 4, with to target part punch forming.Generally it is arranged in lower die 4
There are ring-like forming surface, the concrete shape of ring-like forming surface forming surface should be needed to match according to target part, annular branch herein
Bearing surface 43 is Self-locking angle bearing surface, 5 degree or so of gradient.
Wherein lower die 4 include bottom 42 and multiple lower ends with 42 relatively-stationary valve part 41 of bottom, and the annular of lower die 4
Bearing surface 43 is circumferentially separated on the upper end of each valve part 41 so that when each valve part 41 is to centre, i.e., when being shunk to axis,
Annular bearing surface 43 is sequentially connected in required forming surface, at this time at the time of molding, needs the forming surface to be in close with target part
Fit-state.And when several valve parts 41 are rotated around lower end to detach outward, valve part 41 is then to the need far from target part at this time
Forming surface direction is moved, to unclamp target part.
Wherein lower die 4 is inserted into lower die holder 5, is limited to each valve part 41 circumferentially with the closing in portion by lower die holder 5
Fitting setting successively, to be in tightening state, and then can be molded target part.It should be noted that the effect in closing in portion
It is, each valve part 41 of lower die 4 is applied to axis direction and supports power, with when target shaping workpiece is by the stamping press of upper trimming die
When being transferred to lower die 4, each valve part 41 of lower die 4 will not disperse around, and then can ensure that target forming surface not will disperse,
To ensure the molding to target part.Wherein closing in portion can be annular, can also be other shapes, it is only necessary to being capable of limited target
The shape of part.
In the present embodiment, in the application molding die, workpiece is placed in lower die 4, at the time of molding, lower die holder
5 closing in portion carries out closing in limit to each valve part 41 of lower die 4, to ensure molding of the lower die 4 to target part, and is being molded
Cheng Hou makes the upper end of lower die 4 be detached from grafting along the reversed of plugging direction, and then the upper end of valve part 41 is made to be detached from closing in portion, at this time
The upper end of valve part 41 understands surrounding because not having constraint and scatters, and to unclamp target part, is very easy to so that target part is taken out, and
And target part will not be caused to damage.It is in the molding die, the annular bearing surface 43 of lower die 4 is separately positioned in multiple valve parts 41
On, and contraction limit is carried out to each valve part 41 by the closing in portion of lower die holder 5 at the time of molding, at the time of molding, it is ensured that
Each valve part 41 is shunk, and to ensure to be molded, and when fetched, so that closing in portion is detached from limit, so that valve part 41 scatters to unclamp mesh
Tender, and then easily take out target part.Whole operation is simple and fast, and will not be damaged to target part, to ensure target
The molding effect of part.In conclusion the molding die can efficiently solve the problem of punch forming product is not easily taken out.
Further, in order to more easily release lower die 4 from lower die holder 5, herein preferably, lower die holder 5 and the bottom

It connects and lower die 4 is pushed to be inserted into lower die holder 5, while lower die 4 is pressed down against the first compressed spring 3, until the closing in portion of lower die holder 5
The valve part 41 of lower die 4 is tightened, and after upper trimming die is withdrawn from, the compression elasticity of the first compressed spring 3 will be at this time
Upper ejection lower die 4, so that 4 automatic spring of lower die so that extract or eject manually lower die 4 without staff so that take out
Target part is more prone to.In order to avoid the first compressed spring 3 arbitrarily tampers, it is provided on preferred lower die holder 5 herein for
The locating slot that one compressed spring 3 is positioned.Correspondingly, preferred bottom 42 is slidable in the vertical direction cooperation with lower die holder 5 herein.
Further, in order to make each valve part 41 be more prone to be deflected outward, while ensureing the molding of annular bearing surface 43
Intensity, preferably the upper end radial thickness of each valve part 41 is more than lower end radial thickness herein.Specifically, lower die holder 5 can be made
Closing in portion is in inverted cone-shaped, and makes the upper end of lower die 4 be in and the matched taper in closing in portion, i.e. the upper end combination of each valve part 41
It is tapered.Wherein the apex angle in closing in portion is preferably at 60 degree or so.Correspondingly, in order to further increase the elasticity of valve part 41, this
Locate the middle part of preferred valve part 41, both sides circumferentially offer the groove for improving 41 middle part elasticity of valve part, need to illustrate
It is that the middle part of valve part 41 refers to the middle part of upper and lower directions herein.In order to be molded, while ensureing the degree that surrounding is scattered, herein
Lower die 4 is provided with four pieces of valve parts 41.
Further, in order to more preferably support entire molding die, the lower end of preferred lower die holder 5 is provided with substrate 1, base herein
Plate 1 is connect with 5 screw 2 of lower die holder, and wherein substrate 1 is horizontally disposed, to ensure support effect.
Further, in order to preferably should upper trimming die and the punching press along the vertical direction of lower die 4, herein preferred upper trimming die include
Lower end is provided with the positioning canister portion for being set in 5 upper end of lower die holder and being slidably matched with 5 upper end of lower die holder.
Further, preferred upper trimming die includes that rush-up seat 6, the upper punch 8 being slidably matched with rush-up seat 6 and setting exist herein
The second compressed spring 9 between upper punch 8 and rush-up seat 6 avoids upper punch 8 from accidentally touching other components to protect upper punch 8, because
It is excessive for pressure, and damage.Correspondingly, can be further provided on rush-up seat 6 for the second compressed spring 9
The locating slot of positioning.
The disengaging of upper punch 8 or rush-up seat 6 and 8 excessive compression of upper punch when further, in order to avoid above carrying on red seat 6
Second compressed spring 9 further includes herein preferably limited post 7, and one is radially fitted with limited post in rush-up seat 6 and upper punch 8
7, another fluting that 7 fluctuation range of restricted limited post is set.Specifically can radially it be offered on rush-up seat 6
One cylindrical hole, and open up and vertically extend and groove depth and radially consistent limiting slot, limited post 7 are worn on upper punch 8
If cylindrical hole is simultaneously inserted into limiting slot, can be moved up and down in limiting slot, to pass through the upper and lower ends cell wall of limiting slot
It is limited.
Each embodiment is described by the way of progressive in this specification, the highlights of each of the examples are with other
The difference of embodiment, just to refer each other for identical similar portion between each embodiment.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new
