Description
Technical field
The utility model is related to a kind of mold of compacting powder column more particularly to a kind of powder column compacting opening moulds.
Background technology
Traditional powder column uses integral die system, since blasting explosive granules are during compacting, contact area between particle
Increase with pressing pressure and increase, green compact size expands when release demoulds, and whole moulding/demoulding is difficult and is easy to damage powder column
Surface quality.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of powder column that work efficiency is high compacting opening mould, solves
The difficult technical barrier demoulded after powder column compacting, ensure that the surface quality of powder column.
Technical solution adopted by the utility model to solve its technical problems is：The powder column compacting opening mould includes die sleeve
With the cavity in die sleeve, the cavity is made of two openable and closable molds in semi-circular fastening, the cavity
Outer wall is equipped with taper, and the inner wall of the die sleeve is equipped with the taper to match with the outer wall of the cavity.
In a kind of preferred embodiment that powder column provided by the utility model suppresses opening mould, the taper of the cavity is 1:
1000。
In a kind of preferred embodiment that powder column provided by the utility model suppresses opening mould, the cavity uses alloy material
Matter is made.
Compared with prior art, the advantageous effect of powder column compacting opening mould provided by the utility model is：The utility model
By coordinating cavity design at opening mode structure, and by die sleeve and cavity design tapering, top formula oil pressure can be made full use of
The characteristics of machine, reduces demoulding difficulty, solves the technical barrier that can not be demoulded after powder column compacting, simplifies stripping operation, significantly
Production efficiency is improved, the service life of mold is also improved.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Other attached drawings are obtained, wherein：
Fig. 1 is the structural schematic diagram of powder column compacting opening mould provided by the utility model；
Fig. 2 is the upward view of the cavity for the powder column compacting opening mould that Fig. 1 is provided.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
Also referring to Fig. 1 and Fig. 2, the powder column compacting opening mould 1 includes die sleeve 11 and the cavity in die sleeve 11
12, the cavity 12 is made of two openable and closable molds 122 in semi-circular fastening, and the outer wall of the cavity 12 is equipped with cone
Degree, the inner wall of the die sleeve 11 are equipped with the taper to match with the outer wall of the cavity 12.
Preferably, the taper of the cavity 11 is 1:1000.
Preferably, the cavity 11 is made of alloy material, using the good mechanical property of alloy material, improves mold
Service life, reduce the maintenance cost in later stage.
When it is implemented, being packed into die sleeve 11 after two molds 122 fastening is formed cavity 12, one is put into cavity 12
For quantitative blasting explosive granules by the compacting powder column molding of upper top formula hydraulic press, the inner wall shape and size of the cavity 12 determine powder column
Shape；Since the outer wall of cavity 12 and the inner wall of die sleeve 11 carry 1 when moving back mould:1000 matching taper, so as to easily realize
Modulo operation is moved back, when cavity 12 ejects the height of 11 one third of die sleeve, cavity 12 can be taken out manually, separate two molds
122 can be taken off powder column, and demoulding is simple and will not destroy the surface quality of powder column.
The advantageous effect of powder column provided by the utility model compacting opening mould 1 is：The utility model is by setting cavity 12
The characteristics of counting into opening mode structure, and die sleeve 11 and cavity 12 be designed to taper fit, can make full use of top formula hydraulic press,
Demoulding difficulty is reduced, the technical barrier that can not be demoulded after powder column compacting is solved, simplifies stripping operation, substantially increase production
Efficiency also improves the service life of mold.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is similarly included within the scope of patent protection of the utility model.
