Description
Technical field
The present invention relates to mould applications, more particularly to a kind of compound mould.
Background technology
Compound mould, generally comprises stamping, former, and stamping can be divided into upper punch, bottom punch, upper punch shaping again
The upper surface of product, bottom punch shaping lower surface；The face vertical with end face of female mould forming product.For there is the product of step,
General processing mode has two kinds, and one is that step is set on stamping, and two be increase stamping；When shoulder height is higher, in order to protect
Demonstrate,prove the density uniformity of product, it is necessary to handled by using the mode of " increase stamping "；When product step is relatively low, two kinds of sides
Formula can be used, if using the mode of " step is set on stamping ", the height of step be exactly it is immutable, if one
The product of series, the only height of some step or shape are different, in the case of other all identicals, then need to do multiple differences
Stamping, waste of materials and cost；If using the mode of " increase stamping ", height is the adjustable of change, but due between stamping
Be combined with gap, each time shaping compacting when, the gap of cooperation is all not quite similar, and certain difference is just had between product,
And the mode of " increase stamping ", limited sometimes by press or mould bases, the stamping limited amount that can be set.
The content of the invention
The present invention seeks to avoid the weak point present in above-mentioned prior art, there is provided a kind of compound shaping mould
Tool.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of compound mould, it is characterised in that including former, upper punch, bottom punch, former and upper punch and under
Stamping surrounds a forming cavity, and the upper punch or bottom punch include fix bar, rush body and drift, and the body that rushes is hollow shape
Shape, is provided at both ends with stepped hole, and upper surface is working face, and lower surface is fixing end；The fix bar, which is located at, rushes internal portion, and with
Mates are rushed, the top bar hole for rushing body is engaged with drift, the drift is fastened on the upper end of fix bar, the drift and punching
Regulating block is provided between body.
The drift is connected through a screw thread with fix bar, and the lower surface of the fix bar is slightly above the lower surface for rushing body, Gu
The lower surface of fixed pole is provided with fixing hole, and the upper surface of drift is also provided with fixing hole.
The fixing hole is hex slot or four square grooves.
The quantity of the regulating block is 0-5 blocks.
The fixing end for rushing body is provided with pin-and-hole, and the lower surface for rushing body is provided with inclined-plane, and the angle of inclined-plane and bottom surface is
3-7o, length is 3-5mm.
Also include plug, fix bar is hollow shape, and plug is engaged with the hollow shape of fix bar.
Compared with prior art, the present invention has the beneficial effect that：
1）Compound mould disclosed by the invention, overall stamping divide into four parts, i.e. fix bar, rush body,
Drift, regulating block, the working face of drift can make different shapes or height, it is no longer necessary to make different stampings and adjusted
Section；It can also be adjusted during regulation height by regulating block；Due to drift and fix bar, body is rushed with being combined into affixed, stamping work
The position relative position relation of three will not change when making, therefore solve and " be combined with gap between stamping, each time
During shaping compacting, the gap of cooperation is all not quite similar, and certain difference is just had between product " the problem of.
2）Compound mould disclosed by the invention, the fixing end for rushing body is additionally provided with pin-and-hole, plays the work of positioning stamping
With；The lower surface for rushing body is provided with inclined-plane, and the angle of inclined-plane and bottom surface is 3 ~ 7o, and length is 3-5mm, and this is due to mould in shaping
During compacting, bottom punch and former coordinate, with certain fit clearance, in shaping pressing process, have some powder from
Fallen in gap, these powder will be fallen on around stamping, and are assembled；Inclined-plane can reduce the powder of aggregation to pressing process
Influence, increase pressing process stability, meanwhile, inclined-plane can also reduce stress concentration, can preferably discharge stress, increase
The life-span of mould.
Brief description of the drawings
Fig. 1 is a kind of compound forming die structure schematic diagram of the invention.
In figure：1- fix bars, 2- rushes body, 3- drifts, 4- regulating blocks, 5- pin-and-holes, 6- inclined-planes.
Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of compound mould, including former, upper punch, bottom punch, former and upper punch and lower mould
Punching surrounds a forming cavity, and upper punch or bottom punch include fix bar 1, rush body 2, drift 3；Body 2 is rushed for hollow shape, two ends are set
Stepped hole is equipped with, upper surface is working face, and lower surface is fixing end；Fix bar 1, which is located at, rushes inside body 2, and matches with rushing body 2
Close, the top bar hole for rushing body 2 is engaged with drift 3, drift 3 is fastened on the upper end of fix bar 1, set in drift 3 and rushing between body 2
Regulating block 4 is equipped with, regulating block 4 is used for the height for adjusting the working face of drift 3.
Design feature of the present invention also includes plug, and fix bar 1 is hollow shape, plug and the hollow shape phase of fix bar 1
Coordinate.
Drift 3 is connected through a screw thread with fix bar 1, and the beneath end face of fix bar 1 is slightly above the lower surface for rushing body 2, fixed
The lower surface of bar is provided with fixing hole, and the upper surface of drift is also provided with fixing hole, and the fixing hole is hex slot or four square grooves, regulation
The quantity of block is 0-5 blocks, and the fixing end for rushing body 2 is provided with pin-and-hole 5, plays a part of positioning stamping.
The lower surface for rushing body 2 is provided with inclined-plane 6, and the angle on inclined-plane 6 and bottom surface is 3 ~ 7o, and length is 3-5mm.Because mould exists
During shaping compacting, bottom punch coordinates with former, with certain fit clearance, in shaping pressing process, has some powder
Fallen from gap, these powder will be fallen on around stamping, and are assembled；The setting on inclined-plane of the present invention can reduce aggregation
Influence of the powder to pressing process, increase the stability of pressing process, meanwhile, inclined-plane can also reduce stress concentration, can be compared with
Good release stress, increases the life-span of mould.
The above-mentioned description to embodiment is understood that for ease of those skilled in the art and using this hair
