Abstract
The utility model discloses an isostatic pressure filter element forming die and end sealing elements thereof, wherein the isostatic pressure filter element forming die has reliable end sealing effects. The isostatic pressure filter element forming die comprises a die sleeve and a core rod, wherein two ends of the core rod are respectively installed in the die sleeve through supporting positioning parts to form a die cavity, and the supporting positioning parts are installed on the peripheral wall of the core rod. When the isostatic pressure filter element forming die is placed in pressure media formed in an isostatic pressure mode, at least one of the die sleeve and the core rod conducts elastic deformation towards the inner side of the die cavity in an extruded mode under the action of the pressure media, the end sealing elements are respectively installed between the die sleeve and the core rod and on the outer sides of the supporting positioning parts located on two ends, and the outer end faces of the end sealing elements are provided with deformable annular lips along the inner wall of the die sleeve and/or the outer wall of the core rod. When the isostatic pressure filter element forming die is placed in the pressure media, two lip edges of each deformable annular lip are stretched in the opposite directions under the action of the pressure media. As pressure, on sealing surfaces, exerted by the end sealing elements is increased, the sealing effects are enhanced.

The specific embodiment
As shown in Figure 1, 2, comprise die sleeve 6 and plug 4 Deng static pressure filter core mould, the two ends of described plug 4 are installed in the die sleeve 6 by the support keeper 2 that is arranged on these plug 4 periphery walls respectively, when this mould is placed the pressure medium that carries out isostatic compaction, have at least one will under the effect of pressure medium, take place towards the strain of the inboard extruding of mold cavity in described die sleeve 6 and the plug 4, between described die sleeve 6 and plug 4 and the outside that is positioned at the support keeper 2 at two ends be respectively equipped with end potted component 1.Wherein, die sleeve 6 and plug 4 can take place under the effect of pressure medium simultaneously towards the strain of the inboard extruding of mold cavity, and for this reason, die sleeve 6 and plug 4 all should adopt elastic component; Perhaps, die sleeve 6 is rigid member, and plug 4 is elastic component, and at this moment, plug 4 will take place under the effect of pressure medium towards the strain of the inboard extruding of mold cavity, and die sleeve 6 is indeformable; But best, described plug 4 is rigid member, and die sleeve 6 is elastic component, at this moment, die sleeve 6 will take place under the effect of pressure medium towards the strain of the inboard extruding of mold cavity, and plug 4 is indeformable, can better guarantee the positioning accuracy to plug 4 like this, guarantee the Forming Quality of filter core.When plug 4 was rigid member, for the overall weight of static pressure filter core moulds such as reducing, described plug 4 was preferably hollow pipe.Shown in Figure 1 waiting in the static pressure filter core mould, also be equipped with on the outer wall of described die sleeve 6 be used to the rigidity clamping plate 7 that prevent die sleeve 6 bendings; The two ends that are positioned at rigidity clamping plate 7 on the outer wall of described die sleeve 6 are with clip 8 respectively, thereby are conducive to avoid the bending of die sleeve 6.In addition, the filter core end wall thickness after moulding is excessive, and between described die sleeve 6 and the plug 4 and inboard that is positioned at the support keeper 2 at two ends is respectively equipped with elasticity transition plate 3, and described mold cavity is made up of elasticity transition plate 3, die sleeve 6 and plug 4.Corresponding compression can take place with the extruding of die sleeve 6 in elasticity transition plate 3, and then makes filter core end after the moulding and the wall thickness basically identical at filter core middle part.For the ease of supporting the installation of keeper 2, as shown in Figure 1, 2, described plug 4 is provided with and supports that keeper 2 cooperates and it is carried out the shaft shoulder 401 of axial limiting.Above-mentioned with support keeper 2 preferably adopt steel bushing or with the similar structure of steel bushing, key is the axiality that will guarantee its endoporus (being used for installing plug 4) and its cylindrical (for contacting with die sleeve 6 inwalls), so just can guarantee the uniformity of filter core wall thickness.
As shown in Figure 1, 2, 3, only be equipped with one in the described die sleeve 6 with die sleeve 6 coaxial settings and pass the plug 4 of the end potted component 1 at two ends; Then, the deformable annular lip 101 that a while arranges along the outer wall of the inwall of die sleeve 6 and plug 4 is only arranged on the described outer face of respectively holding potted component 1; When this mould placed described pressure medium, opened under the effect of pressure medium mutually in the opposite direction on two lip limits of described deformable annular lip 101.With the visual angle of Fig. 3, described deformable annular lip 101 is both along the inwall setting of die sleeve 6, simultaneously again along the outer wall setting of plug 4.After pressure medium enters deformable annular lip 101, pressure medium is applied to a pair of opposite power on two lip limits of deformable annular lip 101 respectively, the encapsulant of being close to die sleeve 6 inwalls in the end potted component 1 was further pushed towards die sleeve 6 inwalls, the encapsulant of being close to plug 4 outer walls in the potted component 1 is further pushed towards the outer wall of plug 4, thereby strengthen sealing effectiveness.Obviously, Fig. 1,2, a kind of end potted component 1 that waits static pressure filter core mould has been shown in 3, this end potted component 1 profile is the disk shape, which is provided with and the plug pilot hole, the diameter of described plug pilot hole cooperates with the respective outer diameters of plug 4, the external diameter of described end potted component 1 cooperates with the corresponding internal diameter of die sleeve 6, the cylindrical of upper edge, the outer face end potted component 1 of described end potted component 1 and the interior circle of plug pilot hole are provided with deformable annular lip 101, when the mould such as filter core such as static pressure such as grade that uses this end potted component 1 placed the pressure medium that carries out isostatic compaction, opened under the effect of pressure medium mutually in the opposite direction on two lip limits of described deformable annular lip 101.
The plug 4 of four end potted components 1 at two ends that be arranged in parallel with die sleeve 6 and pass is installed in the described die sleeve 6 as shown in Figure 4; Then, be provided with different deformable annular lips 101 along the inwall of die sleeve 6 and the outer wall of each plug 4 respectively on the described outer face of respectively holding potted component 1; When this mould placed described pressure medium, opened under the effect of pressure medium mutually in the opposite direction on two lip limits of described deformable annular lip 101.With the visual angle of Fig. 4, deformable of ragged edge annular lip 101 is that the inwall along die sleeve 6 arranges; All the other four deformables annular lips 101 are respectively along the outer wall setting of corresponding plug 4.Basically identical among the sealing principle of the end potted component 1 shown in Fig. 4 and Fig. 3.But owing to there are differences among the quantity of plug 4 and distributing position and Fig. 3 among Fig. 4, 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 be positioned at the end potted component inboard the time, end potted component 1 is disk shape solid construction, the external diameter of described end potted component 1 cooperates with the corresponding internal diameter of die sleeve 6, the cylindrical of upper edge, the outer face end potted component of described end potted component 1 is provided with deformable annular lip 101, when the mould such as filter core such as static pressure such as grade that uses this end potted component placed the pressure medium that carries out isostatic compaction, opened under the effect of pressure medium mutually in the opposite direction on two lip limits of described deformable annular lip 101.
