Utility model content

In view of the above-mentioned problems, the utility model proposes a kind of new structure E patterns tool, its can reduce mold design and The complexity of processing is manufactured, reduces mould processing cost, mould reliability is high, improves the efficiency of powder compacting manufacture.

The technical solution of the utility model is as follows：

A kind of E patterns tool, including upper punch, bottom punch and former, in addition to plug, the upper punch and bottom punch are relative Set, the former is arranged between the upper punch and bottom punch, and the die cavity of the former is square die cavity, the core rod position In the square die cavity, the square die cavity occupied by the plug outside part formed E shape die cavities, the upper punch and The cross section of bottom punch is the E shapes of shape and size all same, and the E shapes match with the E die cavities, the upper punch The part relative with plug with bottom punch is cavity.

Further, the plug includes the first plug and the second plug, and first plug includes compacting end and fixation End, second plug includes compacting end and fixing end, the compacting end of first plug and the compacting end of the second plug are worn Cross the cavity of bottom punch and relative with the cavity of the first stamping.

Further, first plug and the second plug are cuboid.

Further, the fixing end of first plug and the fixing end of the second plug are fixedly mounted by fixation kit On plug base.

Further, the fixation kit is mounting flange.

Further, the plug base is fixedly installed in drive device.

Further, cylinder centered on the drive device.

Compared with prior art, the utility model has the advantages that：

(1) it is square die cavity and plug combination by the change in design of E type cavity impressions, greatly reduces cavity impression Difficulty of processing；

(2) knockdown cavity design, the design flexibility of E patterns tool is improved, is that the product specification of E-type magnetic powder core becomes Change provides conveniently；

(3) combined type die cavity compared to Integral die design and manufacture processing complexity and processing cost in terms of all Decrease, when mould is damaged, in that context it may be convenient to change, improve mould reliability.

Embodiment

Exemplary embodiment, feature and aspect of the present utility model are described in detail below with reference to accompanying drawing.It is identical in accompanying drawing Reference represent the same or analogous element of function.Although the various aspects of embodiment are shown in the drawings, remove Non-specifically point out, it is not necessary to accompanying drawing drawn to scale.

As Figure 1-5, E patterns tool of the present utility model includes：Upper punch 1, bottom punch 2, former 3 and plug 4, upper mould Punching 1 and bottom punch 2 are oppositely arranged, and former 3 is arranged between upper punch 1 and bottom punch 2, and the die cavity of former 3 is square die cavity 31, The concrete shape of square die cavity 31 and size are designed according to being actually needed, and plug 4 is located in square die cavity 31, square Part outside die cavity 31 is occupied by plug 4 forms E shape die cavities.As in Figure 3-5, the cross section of upper punch 1 and bottom punch 2 is The E shapes of shape and size all same, the E shapes match with E die cavities, upper punch 1 and the portion relative with plug 4 of bottom punch 2 It is cavity to divide, such setting, can be to the metal dust 5 in E shape die cavities when upper punch 1 and 2 move toward one another of bottom punch Suppressed, and suppress corresponding E shapes part 51, such as E-type magnetic powder core.Preferably, plug 4 includes shapes and sizes all same The first plug and the second plug, the shapes and sizes of the first plug and the second plug can design according to being actually needed, Preferably, the first plug and the second plug are cuboid.First plug includes the compacting end and use for pressed metal powder In the fixing end of stationary core rod, the second plug also includes the compacting end for pressed metal powder and consolidating for stationary core rod 4 Fixed end, the compacting end of the first plug and the compacting end of the second plug both pass through the cavity of bottom punch 2 and the sky with the first stamping Chamber is relative.The fixing end of first plug and the fixing end of the second plug are fixedly mounted on plug base 6 by fixation kit, Preferably, it is fixed by mounting flange 7.When powder core is suppressed, because considering to press magnet ring, press is designed with central cylinder 8, will Plug base 6 is fixedly installed in central cylinder 8 by helicitic texture, central cylinder 8 can be used as drive device driving plug base 6 and then Driving plug 4 moves with former 3, forms E shape die cavities.

During E types mold work of the present utility model, as shown in Figure 3-4, former 3 rises, promotion of the plug 4 in central cylinder 8 Under, assigned position is risen to former 3, bottom punch 2 is motionless, and square die cavity 31 and the plug 4 of former 3 form E shape die cavities, Then to filling metal dust 5 in E shape die cavities；Subsequent upper punch pushes the metal dust 5 in compacting E shape die cavities, former 3, plug 4 Remained stationary as with bottom punch 2, after the completion of compacting, upper punch 1, which rises, is back to initial position, and subsequent bottom punch 2 is motionless, former 3 Decline and central cylinder 8 drives plug 4 to decline, the upper surface of upper surface, the upper surface of plug 4 and bottom punch 2 when former 3 is in During approximately the same plane, such as E shapes magnetic core of E shapes part 51 for suppressing completion completes the demoulding, and compacting terminates.

The change in design of E type cavity impressions is square die cavity and plug combination by E patterns of the present utility model tool, significantly Reduce the difficulty of processing of cavity impression；And knockdown cavity design, the design flexibility of E patterns tool is improved, is E types The product specification change of powder core provides conveniently.

Finally it should be noted that：Above-described each embodiment is merely to illustrate the technical solution of the utility model, rather than It is limited；Although the utility model is described in detail with reference to the foregoing embodiments, one of ordinary skill in the art It should be understood that：It can still modify to the technical scheme described in previous embodiment, or to which part or whole Technical characteristic carries out equivalent substitution；And these modifications or substitutions, the essence of appropriate technical solution is departed from the utility model The scope of each embodiment technical scheme.
