The present invention is a kind of new powder metallurgy split middle mold with the level, including middle mold, the middle mold is for Split type structure and including upper modules and lower mold, the upper modules upper and lower surface is respectively equipped with cavity volume and step, groove is provided with this cavity volume, the lower mold upper surface is ledge structure, draw-in groove is provided with the middle part of this ledge structure, the step of lower mold is connected together with concentric gap cooperation with the cavity volume of upper modules, micro- shoulder central module is connected with the groove of upper modules, it is connected with without shoulder central module in the step draw-in groove of lower mold, micro- shoulder central module and the planar contact without shoulder central module are arranged with multiple small oil grooves to pressure release.Using technical solution of the present invention, can effectively prevent the stress concentration at middle mold step, it is to avoid the generation of crackle, the pressure of shaping can be improved and the mold use life-span is significantly improved, and change module easily, reduces cost.

Description

A kind of new powder metallurgy split middle mold with the level
Technical field
The invention belongs to shaping powder metallurgy product field, and in particular in a kind of new powder metallurgy split with the level Mould.
Background technology
Existing power metallurgical shaping middle mold is generally straight tube structure, but for the whole of multi-step sintered metal product Shape, needs special shaping special plane, is limited by current trimmer manufacturing technology and cost, portion is carried out usually on mould structure Decomposition is determined.At present monoblock type step middle mold concentrates produced problem, is exactly the stress concentration at step, and mould easily collapses damage, separately Due to the presence of hydraulic oil during outer shaping, shaping pressure can not be very big.
When middle mold is overall structure, with the increase of Production Life, when middle mold part wears, middle mold needs integral replacing, Life-span is than relatively low.
The content of the invention
The present invention takes split middle mold design, eliminates the stress concentration at middle mold step, lays down shaping oil part oil Pressure, when preventing shaping pressure excessive, step is damaged;Mould junction be clear angle, protection product edge will not it is whole go out fillet;In addition When mould part weares and teares, can be changed for wearing part.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is achieved through the following technical solutions:
A kind of new powder metallurgy split middle mold with the level, including middle mold, the middle mold is for Split type structure and including upper Portion's module and lower mold, the upper modules upper and lower surface are respectively equipped with cavity volume and step, are provided with groove, institute in this cavity volume It is ledge structure to state lower mold upper surface, and draw-in groove, the step and upper modules of lower mold are provided with the middle part of this ledge structure Cavity volume with concentric gap coordinate be connected together, micro- shoulder central module is connected with the groove of upper modules, in lower die It is connected with the step draw-in groove of part without shoulder central module, micro- shoulder central module and the plane contact part without shoulder central module Multiple small oil grooves are provided with to pressure release.
Further, micro- shoulder central module with without shoulder central module junction be cutting edge of a knife or a sword side.
Further, micro- shoulder central module and two small oil grooves are arranged with without shoulder central module planar contact, The card access surface of upper modules and lower mold is provided with gap from inside to outside simultaneously, it is ensured that the inside and outside connection of small oil groove.
Further, the small oil groove avoids micro- shoulder central module and the shaping without shoulder central module plane contact part Significant surface.
Further, the cavity volume and groove of the upper modules is ground by inner circle, and roughness is within Ra0.1, described The step draw-in groove of lower mold is ground by inner circle, and roughness is within Ra0.1.
Further, the upper modules and lower mold are equipped with screwed hole, for dismounting and changing.
The invention has the beneficial effects as follows:
1st, using the shaping middle mold of the present invention, the stress concentration at middle mold step can effectively be prevented, it is to avoid the generation of crackle, The pressure of shaping can be improved and the mold use life-span is significantly improved.
2nd, can the very easily easy abrasion of more mold exchange part, improve the mold use life-span, reduce cost.
Description of the drawings
Fig. 1 is the structure sectional view of the present invention;
Structure top views of the Fig. 2 for the present invention(Locally).
Label declaration in figure:1st, lower mold, 2, without shoulder central module, 3, micro- shoulder central module, 4, upper modules.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in seeing figures.1.and.2, a kind of new powder metallurgy split middle mold with the level, including middle mold, the middle mold is Split type structure and including upper modules 4 and lower mold 1, in the present embodiment, upper modules 4 and lower mold 1 adopt 45# Steel hot jacket, 4 upper and lower surface of the upper modules are respectively equipped with cavity volume and step, and groove, the lower die are provided with this cavity volume 1 upper surface of part is ledge structure, and draw-in groove, the step of lower mold 1 and the cavity volume of upper modules 4 are provided with the middle part of this ledge structure Coordinated with Φ 80H/h5 concentric gaps and be connected together, micro- shoulder central module 3 is connected with the groove of upper modules 4, under Be connected with the step draw-in groove of portion's module 1 without shoulder central module 2, micro- shoulder central module 3 and without shoulder central module 2 be hard alloy Core rod, micro- 3 bottom of shoulder central module be the transition of cutting edge of a knife or a sword side, it is to avoid fillet, micro- shoulder central module 3 and without between shoulder central module 2 protect Hold 0.005mm perpendicularity and axiality, it is ensured that quality of fit, the tolerance between each mating surface has been marked in the present embodiment Fig. 1 Coordinate and roughness size, micro- shoulder central module 3 and the planar contact without shoulder central module 2 are arranged with multiple small oil grooves and use With pressure release.
Micro- shoulder central module 3 be cutting edge of a knife or a sword side without 2 junction of shoulder central module.
Micro- shoulder central module 3 and two small oil grooves are arranged with without 2 planar contact of shoulder central module, while top The card access surface of module 4 and lower mold 1 is provided with 0.5mm gaps from inside to outside, it is ensured that the inside and outside connection of small oil groove.
The small oil groove avoids micro- shoulder central module 3 and the shaping significant surface without 2 plane contact part of shoulder central module.
The cavity volume and groove of the upper modules 4 is ground by inner circle, roughness within Ra0.1, the lower mold 1 Step draw-in groove ground by inner circle, roughness is within Ra0.1.
