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.

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 arranged in die sleeve 6 by the supporting positioning member 2 that is arranged on these plug 4 periphery walls respectively, when this mould is placed in the pressure medium that carries out isostatic compaction, have at least one will occur under the effect of pressure medium towards the strain of the inboard extruding of mold cavity in described die sleeve 6 and plug 4, between described die sleeve 6 and plug 4 and the outside that is positioned at the supporting positioning member 2 at two ends be respectively equipped with end potted component 1.Wherein, die sleeve 6 and plug 4 can occur 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 occur 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 occur under the effect of pressure medium towards the strain of the inboard extruding of mold cavity, and plug 4 is indeformable, can better guarantee like this positioning accuracy to plug 4, 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.In mould such as filter core such as static pressure such as grade shown in Figure 1, 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 overlapped respectively clip 8 are arranged, thereby are conducive to avoid the bending of die sleeve 6.In addition, the filter core end wall thickness after the moulding is excessive, and between described die sleeve 6 and the plug 4 and inboard that is positioned at the supporting positioning member 2 at two ends is respectively equipped with elasticity transition plate 3, and described mold cavity is comprised of elasticity transition plate 3, die sleeve 6 and plug 4.Corresponding compression can occur with the extruding of die sleeve 6 in elasticity transition plate 3, and then makes filter core end and the wall thickness in the middle part of filter core after moulding 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 is carried out the shaft shoulder 401 of axial limiting.Above-mentioned and supporting positioning member 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 described die sleeve 6 with the coaxial setting of die sleeve 6 and pass the plug 4 of the end potted component 1 at two ends; , 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 described outer face of respectively holding potted component 1; When this mould was placed in 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 respectively a pair of opposite power on two lip limits of deformable annular lip 101, both made the encapsulant of being close to die sleeve 6 inwalls in end potted component 1 further towards die sleeve 6 inwall extruding, the encapsulant of being close to plug 4 outer walls in 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 disc-shaped, which is provided with and the 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 coordinates with the corresponding internal diameter of die sleeve 6, be provided with deformable annular lip 101 along the cylindrical of end potted component 1 and the inner circle of plug pilot hole on the outer face of described end potted component 1, when the mould such as filter core such as static pressure such as grade that uses this end potted component 1 is placed in the pressure medium that carries out isostatic compaction, open under the effect of pressure medium mutually in the opposite direction on two lip limits of described deformable annular lip 101.
As shown in Figure 4, four plugs 4 that be arranged in parallel with die sleeve 6 and pass the end potted component 1 at two ends are installed in described die sleeve 6; , 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 described outer face of respectively holding potted component 1; When this mould was placed in 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 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 also difference to some extent of the form that arranges of deformable annular lip 101.
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 the disc-shaped solid construction, the external diameter of described end potted component 1 coordinates with the corresponding internal diameter of die sleeve 6, cylindrical along the end potted component on the outer face of described end potted component 1 is provided with deformable annular lip 101, when use this end potted component wait static pressure filter core mould to be placed in the pressure medium that carries out isostatic compaction the time, open under the effect of pressure medium mutually in the opposite direction on two lip limits of described deformable annular lip 101.
