Abstract
An isostatic pressing forming die for compaction blanks of a powder forming crucible comprises a rigid interior die, an elastic appearance rubber sleeve and a rigid sealing end plug. The elastic appearance rubber sleeve is positioned on the periphery of the outer side of the rigid interior die, the rigid sealing end plug is positioned above the rigid interior die and sealed with the top end of the elastic appearance rubber sleeve, and a powder forming cavity is formed among the rigid interior die, the elastic appearance rubber sleeve and the rigid sealing end plug. Density distribution of isostatic pressed forming blanks can be guaranteed, dimensions of inner cavities are precise, a large amount of raw material powder and resources are saved, and simultaneously, mechanical processing workload is reduced.
Description
Technical field
The utility model relates to the forming material powder mould, specifically is a kind of isostatic compaction mould of powder compacting crucible pressed compact.
Background technology
Under conditions such as existing technology, equipment, mould,, need through modes such as compression moulding, sintering with single powder or various powders industrial products as raw material production.In process of production, multiple factors such as technology, equipment, mould all might cause the material quality defects, do not reach requirement like density, intensity, homogeneity.Simultaneously, adopt existing production technology, also have the single defective of machine-shaping shape.Modern industry requires complicated and changeable to shape of product, therefore add man-hour at the material to single shape, just need reserve a large amount of allowance for later stage fine finishining, could satisfy the demand of modern industry, causes the lot of materials waste.Existing technology pattern no matter on the internal soundness of material or on the machining shape, all can not satisfy existing needs preferably, therefore changes technology, equipment, the mould produced and just seems very necessary.
Static pressure press pressed powder parison base substrates such as existing following several method:
1, mould adopts cylinder, cuboid, and this method is to adopt the profile gum cover to do volume, powder is put into gum cover after preformed, or powder is directly put into gum cover, again feeding end is added seal cover (plug) sealing, puts into isostatic pressing machine then, the compression moulding of exerting pressure.No matter but be that cylinder, cuboid etc. are not industrial enterprise's desired end product shapes; Later stage need be passed through a large amount of machining; And stock utilization is very low (to require particularly that cylinder makes crucible, cuboid makes boat; All need a person with the qualifications of a general the material the centre empty, so waste of material is very big).
2, tubulose blank molding, this method are to adopt rigidity outer die casing and soft internal mold gum cover or soft external mold gum cover and the interior die sleeve formation of the rigidity mezzanine space powder of packing into, put into isostatic pressing machine after the sealing, the compression moulding of exerting pressure.The tubulose base of this method compacting, the moulding that can not solve crucible, boat etc.
The utility model content
The purpose of the utility model is the deficiency that overcomes above-mentioned existence, provides a kind of simple in structure, product cavity size of making moulding precisely and save material, reduce the isostatic compaction mould of the powder compacting crucible pressed compact of machining workload.
The technical scheme that the utility model is adopted to achieve these goals is:
A kind of isostatic compaction mould of powder compacting crucible pressed compact; It is characterized in that comprising shape mould, elasticity profile gum cover and rigid seal end plug in the rigidity; Said elasticity profile gum cover is positioned at around the rigidity shape mould outside; The rigid seal end plug be positioned at rigidity shape mould top and with elasticity profile gum cover end sealing, form the powder compacting die cavity in the said rigidity between shape mould, elasticity profile gum cover and the rigid seal end plug three.
According to the isostatic compaction mould of a kind of powder compacting crucible pressed compact described in the utility model, it is characterized in that said powder compacting die cavity is crucible shape or boat shape.
The beneficial effect of the utility model mainly embodies as follows: the Density Distribution that has guaranteed the isostatic compaction base is even, and inner cavity size is accurate, and has practiced thrift a large amount of former material powders, has practiced thrift resource, has reduced the workload of machining simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure: shape mould in the 1-rigidity, 2-elasticity profile gum cover, 3-rigid seal end plug, 4-powder compacting die cavity.
The specific embodiment
To combine accompanying drawing that the technical scheme of the utility model is further specified below.
A kind of isostatic compaction mould of powder compacting crucible pressed compact comprises shape mould 1, elasticity profile gum cover 2 and rigid seal end plug 3 in the rigidity.Wherein elasticity profile gum cover 2 is positioned at around rigidity shape mould 1 outside; Rigid seal end plug 3 be positioned at rigidity shape mould 1 top and with elasticity profile gum cover 2 end sealings, form powder compacting die cavity 4 in the said rigidity between shape mould 1, elasticity profile gum cover 2 and rigid seal end plug 3 threes.This powder compacting die cavity 4 needs the Parison Shape of compression moulding for crucible shape or boat shape etc.
Utilize the method or the principle of this mould pressed compact moulding to be: with powder (as: metal dust, non-metal powder, metal and nonmetal mixed-powder, several kinds of nonmetal and nonmetal mixed-powders; Powdered graphite, SiO 2 powder etc.) be filled in the powder compacting die cavity 4; After putting mould such as is put at the static pressure transmission medium and exert pressure, elasticity profile gum cover 2 just can be inside, and two ends are to the intermediate compression moulding; And the shape mould has only micro-strain in the rigidity; Therefore adopt this fixedly method at internal mold compression external mold and two ends thereof, guaranteed that pressed compact inner cavity sizes such as crucible, boat are accurate, suppress the parison consistent in density simultaneously.
The utility model is not limited in above embodiment, and the change of on the basis of the utility model, making without creative work also belongs to the protection domain of the utility model.
