Abstract
The invention discloses an isostatic pressing filter element molding die and end sealing elements thereof, wherein the isostatic pressing filter element molding die has a reliable end sealing effect. The die comprises a die sleeve and a core rod, wherein two ends of the core rod are installed in the die sleeve through support positioning pieces arranged on the periphery wall of the core rod to further form a die cavity. When the die is placed in a pressure medium formed in an isostatic compaction mode, both the die sleeve and the core rod or the die sleeve or the core rod is deformed towards the inner side of the die cavity in an extruding and elastic mode under the action of the pressure medium. The end sealing elements are respectively arranged outside the support positioning pieces at two ends and between the die sleeve and the core rod, wherein deformable annular lip mouths are formed in the outer end faces of the end sealing elements along the inner wall of the die sleeve and / or the outer wall of the core rod, and when the die is placed in the pressure medium, two lips of each deformable annular lip mouth open towards opposite directions under the action of the pressure medium. Due to the fact that pressure applied on a sealing surface by the end sealing elements is increased, the sealing effect is strengthened.

Detailed description of the invention
As shown in Figure 1, 2, isostatic pressed filter core mould comprises die sleeve 6 and plug 4, the two ends of described plug 4 are arranged in die sleeve 6 respectively by the supporting positioning member 2 be arranged on this plug 4 periphery wall, when this mould is placed in the pressure medium carrying out isostatic compaction, an elastic deformation that will occur to extrude inside mold cavity under the effect of pressure medium is had at least, between described die sleeve 6 and plug 4 and the outside being positioned at the supporting positioning member 2 at two ends is respectively equipped with end potted component 1 in described die sleeve 6 and plug 4.Wherein, can there is the elastic deformation extruded inside mold cavity in die sleeve 6 and plug 4 under the effect of pressure medium simultaneously, and for this reason, die sleeve 6 and plug 4 all should adopt elastic component; Or die sleeve 6 is rigid member, and plug 4 is elastic component, at this moment, the elastic deformation that plug 4 will occur to extrude inside mold cavity under the effect of pressure medium, and die sleeve 6 is indeformable; But best, described plug 4 is rigid member, and die sleeve 6 is elastic component, at this moment, the elastic deformation that die sleeve 6 will occur to extrude inside mold cavity under the effect of pressure medium, and plug 4 is indeformable, better can ensure the positioning precision to plug 4 like this, guarantee the Forming Quality of filter core.When plug 4 is rigid member, in order to reduce the overall weight of isostatic pressed filter core mould, described plug 4 is preferably hollow pipe.In the isostatic pressed filter core mould shown in Fig. 1, the outer wall of described die sleeve 6 is also provided with for preventing the rigidity clamping plate 7 that die sleeve 6 is bending; The two ends outer wall of described die sleeve 6 being positioned at rigidity clamping plate 7 are overlapped respectively and are had clip 8, thus are conducive to avoiding the bending of die sleeve 6.In addition, in order to avoid the filter core end wall after shaping is thicker than greatly, between described die sleeve 6 and plug 4 and the inner side being positioned at the supporting positioning member 2 at two ends is respectively equipped with elasticity transition sheet 3, described mold cavity is made up of elasticity transition sheet 3, die sleeve 6 and plug 4.Corresponding compression can be there is with the extruding of die sleeve 6 in elasticity transition sheet 3, so make shaping after filter core end and wall thickness in the middle part of filter core basically identical.For the ease of the installation of supporting positioning member 2, as shown in Figure 1, 2, described plug 4 is provided with and coordinates with supporting positioning member 2 and it to be carried out to the shaft shoulder 401 of axial limiting.Above-mentionedly preferably adopt steel bushing or the structure similar with steel bushing with supporting positioning member 2, key be to ensure its endoporus (for installing plug 4) and its cylindrical (for die sleeve 6 contact internal walls) axiality, so just can guarantee the uniformity of filter core wall thickness.
As shown in Figure 1, 2, 3, be only provided with one in described die sleeve 6 arrange with die sleeve 6 is coaxial and passes the plug 4 of the end potted component 1 at two ends; Then, the outer face of described each end potted component 1 only there is the deformable annular lip 101 arranged along the inwall of die sleeve 6 and the outer wall of plug 4 while of; When this mould is placed in described pressure medium, two lip limits of described deformable annular lip 101 are opened in the opposite direction mutually under the effect of pressure medium.With the visual angle of Fig. 3, described deformable annular lip 101 was both arranged along the inwall of die sleeve 6, arranged again along the outer wall of plug 4 simultaneously.After pressure medium enters deformable annular lip 101, a pair contrary power on two lip limits that pressure medium is applied to deformable annular lip 101 respectively, both the encapsulant being close to die sleeve 6 inwall in end potted component 1 had been made further to extrude towards die sleeve 6 inwall, make again the encapsulant being close to plug 4 outer wall in potted component 1 further extrude towards the outer wall of plug 4, thus strengthen sealing effectiveness.Obviously, Fig. 1, 2, a kind of end potted component 1 of isostatic pressed filter core mould has been shown in 3, this end potted component 1 profile is disc-shaped, which is provided with and plug pilot hole, the diameter of described plug pilot hole coordinates with the respective outer diameters of plug 4, the external diameter of described end potted component 1 and the corresponding minor diameter fit of die sleeve 6, the outer face of described end potted component 1 is provided with deformable annular lip 101 along the end cylindrical of potted component 1 and the inner circle of plug pilot hole, when using the isostatic pressed filter core mould of this end potted component 1 to be placed in the pressure medium carrying out isostatic compaction, two lip limits of described deformable annular lip 101 are opened in the opposite direction mutually under the effect of pressure medium.
As shown in Figure 4, be provided with four in described die sleeve 6 to be arranged in parallel with die sleeve 6 and the plug 4 passing the end potted component 1 at two ends; Then, the outer face of described each end potted component 1 is provided with different deformable annular lip 101 along the inwall of die sleeve 6 and the outer wall of each plug 4 respectively; When this mould is placed in described pressure medium, two lip limits of described deformable annular lip 101 are opened in the opposite direction mutually under the effect of pressure medium.With the visual angle of Fig. 4, a deformable annular lip 101 of ragged edge arranges along the inwall of die sleeve 6; All the other four deformable annular lip 101 are arranged along the outer wall of corresponding plug 4 respectively.Basically identical in the sealing principle of the end potted component 1 shown in Fig. 4 and Fig. 3.But owing to there are differences in the quantity of plug in Fig. 44 and distributing position and Fig. 3, therefore, the form that arranges of deformable annular lip 101 is also distinguished to some extent.
As shown in Figure 5, when the end of plug is positioned at the inner side of end potted component, end potted component 1 is disc-shaped solid construction, the external diameter of described end potted component 1 and the corresponding minor diameter fit of die sleeve 6, the outer face of described end potted component 1 is provided with deformable annular lip 101 along the cylindrical of end potted component, when using the isostatic pressed filter core mould of this end potted component to be placed in the pressure medium carrying out isostatic compaction, two lip limits of described deformable annular lip 101 are opened in the opposite direction mutually under the effect of pressure medium.
