Abstract
The utility model discloses a kind of metal powder injection molding non-conventional type joint to sinter tool, it is mainly used in the sintering of metal non-conventional type joint, including main body tool and auxiliary fixture, the auxiliary fixture includes limit for width tool and support jig, main body tool surface is main to be provided with empty avoiding groove and supporting plane, supporting plane coordinates with metal non-conventional type joint lower plane, and limit for width tool coordinates with metal non-conventional type joint outer surface, and main body tool is piled up with 6 sets of auxiliary fixtures to be applied in combination.The utility model can effectively prevent the advantages of metal powder injection molding non-conventional type joint cracked in sintering process, deformation, bending etc. are bad, and tool makes simply, puts and is neatly easy to field management, and service efficiency is high.
Description
Technical field
It the utility model is related to a kind of sintering tool, and in particular to a kind of metal powder injection molding non-conventional type joint sintering
Tool.
Background technology
It is metal powder injection molded（MIM）Technology has developed rapidly as automobile component, doctor is widely used in the past 20 years
The new near-net-shape technology of apparatus, 3C components and aerospace field is treated, there is formed precision height, tissue to have, performance
The features such as excellent, there is unique advantage especially for 0.1-200g widgets.It uses metal dust and binding agent mixing, banburying
Formed feeding injects mold cavity through injector and green blank is made, and blank turns into crisp after degreasing removes portion of binder
Weak brown blank, then turn into silver-colored blank by high temperature sintering densification, structure needed for final acquisition.But brown blank is very fragile,
It is easily cracked, and during sintering densification, under the influence of gravity and internal stress, also easily there is flexural deformation, collapse
Collapse etc. bad, greatly reduce the yield of product.
The content of the invention
The utility model provides a kind of metal powder injection molding for non-conventional type joint sintering Collapse Deformation problem and burnt
Tool is tied, can effectively reduce bad generation of the part in sintering process, greatly improves the yield of product.
The utility model is achieved through the following technical solutions：A kind of metal powder injection molding non-conventional type joint burns
Tool is tied, is mainly used in the sintering of metal non-conventional type joint, including main body tool and auxiliary fixture, the auxiliary fixture include
Limit for width tool and support jig, main body tool surface is main to be provided with empty avoiding groove and supporting plane, and supporting plane is different with metal
Shape connector lower plane coordinates, and limit for width tool coordinates with metal non-conventional type joint outer surface, main body tool and 6 sets of auxiliary fixture heaps
Block is applied in combination.
As preferable technical scheme, the limit for width tool and support jig form by rectangular blocks.
As preferable technical scheme, the height of the support jig highly selects according to metal non-conventional type joint finished product.
As preferable technical scheme, often covering auxiliary fixture includes two limit for width tools and a support jig.
As preferable technical scheme, sintering tool is made using the good corundum ceramic of heat endurance.
The beneficial effects of the utility model are：The utility model can effectively prevent metal powder injection molding abnormity connection
Part is cracked in sintering process, deformation, bending etc. are bad, and tool makes simple, puts and neatly is easy to field management, use
The advantages of efficiency high.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the stereogram that metal powder injection molding non-conventional type joint sinters tool；
Fig. 2 is the three-dimensional exploded view of the utility model metal powder injection molding non-conventional type joint sintering tool；
Fig. 3 is the assembling stereogram of the utility model metal powder injection molding non-conventional type joint sintering tool.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically chatting
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1-Figure 3, a kind of metal powder injection molding non-conventional type joint sintering tool 1, it is different to be mainly used in metal
The sintering of shape connector 2, it is characterised in that including：Main body tool 5 and auxiliary fixture（Limit for width tool 3, support jig 4）, main body
Tool 5 surface distributed, 6 grooves, supporting plane coordinate with the lower plane of metal non-conventional type joint 2, and recess width designs appropriate empty avoiding
To prevent metal non-conventional type joint 2 from being damaged after shrinking, limit for width tool 3 and support jig 4 then form by rectangular blocks, limit for width
Tool 3 coordinates with metal non-conventional type joint outer surface, and the height of support jig 4 is highly set according to metal non-conventional type joint finished product
Meter, the support of the support jig 4 is obtained after product sintering shrinkage and avoid caving in bad, 1 main body tool 5 and 6 sets
Auxiliary fixture（Two limit for width tools 3 and 1 support jig 4）Pile up and be applied in combination, the sintering tool 1 is good using heat endurance
Corundum ceramic make.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
