Abstract
The utility model relates to a compact alloy powder forming die, which comprises an elastic PP (Polypropylene) inner die, a rigid PP outer die sleeve and an elastic PP sealing plug; the rigid PP outer die sleeve is arranged on the outer periphery of the elastic PP inner die; the elastic PP sealing plug is arranged on the elastic PP inner die and wraps the upper end of the rigid PP outer die sleeve peripherally; the bottom periphery of the elastic PP inner die wraps the bottom of the rigid PP outer die sleeve; and the elastic PP inner die, the rigid PP outer die sleeve and the elastic PP sealing plug are connected to form an alloy powder forming cavity. With the adoption of the forming die disclosed by the utility model, the density distribution is uniform during the isostatic pressing process, and the compactness is good.
Description
Technical field
The utility model relates to the alloy powder mould.
Background technology
Under conditions such as present technology, equipment, mould, the industrial products so that single powder or various powders are produced as raw material need by modes such as compression moulding, sintering.In process of production, multiple factors such as technology, equipment, mould all might cause material quality problems to occur, do not reach requirement as density, intensity, homogeneity.For example, present mould generally all is to adopt rigid material to make, and causes that mould is put into and wait the static pressure transmission medium discontinuity of exerting pressure, and makes that the shaped article density unevenness is spared, compactness is poor.
The utility model content
The purpose of this utility model is to propose a kind of densified alloy powder mould, and it can solve, and density unevenness is even, the problem of compactness difference.
In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:
A kind of densified alloy powder mould, it comprises elasticity PP(Polypropylene, polypropylene) inner mold, be arranged on the outside rigidity PP outer die casing all around of elasticity PP inner mold, and be arranged on elasticity PP inner mold top and coat the elasticity PP sealing-plug of rigidity PP outer die casing upper end all around, coat the bottom of described rigidity PP outer die casing around the elasticity PP inner mold bottom, elasticity PP inner mold, rigidity PP outer die casing and elasticity PP sealing-plug are connected to form alloy powder moulding die cavity.
Preferably, has seal washer between elasticity PP inner mold and the rigidity PP outer die casing.
Preferably, has sealing ring between rigidity PP outer die casing and the elasticity PP sealing-plug.
The utlity model has following beneficial effect:
Guaranteed in the Density Distribution of isostatic compaction evenly, compactness is good.
Description of drawings
Fig. 1 is the schematic cross-section of the densified alloy powder mould of the utility model preferred embodiment.
Reference numeral: 1, elasticity PP sealing-plug; 2, rigidity PP outer die casing; 3, elasticity PP inner mold; 4, alloy powder moulding die cavity.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, a kind of densified alloy powder mould, it comprises elasticity PP inner mold 3, be arranged on the outside rigidity PP outer die casing 2 all around of elasticity PP inner mold 3, and be arranged on elasticity PP inner mold 3 tops and coat the elasticity PP sealing-plug 1 of rigidity PP outer die casing 2 upper ends all around, coat the bottom of described rigidity PP outer die casing 2 around elasticity PP inner mold 3 bottoms, elasticity PP inner mold 3, rigidity PP outer die casing 2 and elasticity PP sealing-plug 1 are connected to form alloy powder moulding die cavity 4.
In order to guarantee sealing, has seal washer between elasticity PP inner mold 3 and the rigidity PP outer die casing 2.Has sealing ring between rigidity PP outer die casing 2 and the elasticity PP sealing-plug 1.
The principle of present embodiment is in this way: alloy powder is filled in the alloy powder moulding die cavity 4, the static pressure transmission medium such as then the mould of present embodiment being put into exerts pressure, elasticity PP inner mold 3 is outside, two ends to the third side to compression forming, rigidity PP outer die casing 2 has miniature deformation, make stressed evenly, it is good that the density that has guaranteed shaped article evenly reaches compactness.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
