Referring to Fig. 1 and Fig. 2, vacuum interrupter of the invention is encapsulated to use four-plate mould, including the first cope plate 3, second
Cope plate 4, the first lower template 5 and the second lower template 6, first cope plate 3, the second cope plate 4, the first lower template 5 and
Two lower templates 6 are sequentially stacked and form the die cavity of accommodating vacuum interrupter 100 from top to bottom.
The top of first cope plate 3 is provided with upper-mould top 2, and the upper-mould top 2 is fixed with first cope plate 3
Connection, it is fixedly connected with mode and can be connected by screw bolts.The top of the upper-mould top 2 is provided with upper mould thermal insulation board 1, for mould
The insulation of tool.Certainly, the upper mould thermal insulation board 1 can also be arranged between first cope plate 3 and upper-mould top 2.
The lower section of second lower template 6 is provided with lower mould bottom plate 8, and the lower mould bottom plate 8 is fixed with second lower template 6
Connection, it is fixedly connected with mode and can be connected by screw bolts.Between second lower template 6 and lower mould bottom plate 8 be provided with lower mould every
Hot plate 7, the insulation for mould.
Through hole 31 is offered on first cope plate 3, second cope plate 4 is provided with stop screw 9, described spacing
Screw 9 runs through the through hole 31, and its head is threadedly coupled with second cope plate 4, its afterbody 91 and first cope plate 3
Between leave gap L.When upper-mould top 2 drives the first cope plate 3 to move up, afterbody 91 and institute by stop screw 9
State and leave gap L between the first cope plate 3, so when the first cope plate 3 is begun to move up, second cope plate 4 is not
It can be moved up with the first cope plate 3, after the afterbody 91 of stop screw 9 contacts with second cope plate 4, described second
Cope plate 4 can just move up with the first cope plate 3, at this moment disengaged between the cope plate 4 of the first cope plate 3 and second away from
Size from the gap L left between the afterbody 91 by stop screw 9 and first cope plate 3 determines.The usual gap
Size can be 10mm, and the size can be adjusted by rotating the stop screw 9.
The lower template 6 of second cope plate 4 and second is connected by removable connector 10, the removable connector 10
Connected mode can use conventional dismountable mechanical connected mode, as can preferably use clamping, when described in external force driving
Second cope plate 4 moves up, and when the second lower template 6 remains stationary as, can disengage removable connector 10.
The first ejector retainner plate 11 and the second ejector retainner plate 12 are provided with the lower mould bottom plate 8, first ejector retainner plate 11 is provided with
First thimble 13, first thimble 13 run through second lower template 6, and its end can be with the vacuum extinction in the die cavity
Room 100 abuts, and is abutted shown in Fig. 2 for the first thimble 13 with the moved end of vacuum interrupter 100 and static side fixed mechanism
State, certainly, first thimble 13 can also be used and abutted with other positions of vacuum interrupter 100, and described first
Thimble 13 be used for it is encapsulated after vacuum interrupter 100 the demoulding, can when the first thimble of shelves 13 moves up with the first ejector retainner plate 11
Promote the vacuum interrupter 100 to move up, depart from the first lower template 5.Second ejector retainner plate 12 is provided with the second thimble 14, institute
State the second thimble 14 and run through second lower template 6, its end is fixedly connected with first lower template 5, second thimble
When plate 12 moves up, first lower template 5 can be driven to move up, so as to depart from the second lower template 6.
The present invention vacuum interrupter it is encapsulated with four-plate mould when being stripped after the completion of encapsulated to vacuum interrupter,
Upper-mould top 2 drives the first cope plate 3 to move up first, due to stop screw 9 afterbody 91 and first cope plate 3 it
Between leave gap L, the first cope plate 3 and the second cope plate 4 disengage first, state as shown in Figure 4；When the afterbody of stop screw 9
After 91 contact with first cope plate 3, the second cope plate 4 is driven to be moved up with the first cope plate 3, removable connector 10
Open, the second cope plate 4 and the first lower template 5 disengage, state as shown in Figure 5；Next, the first ejector retainner plate 11 and the second thimble
Plate 12 synchronously moves up, and the second thimble 14 drives the first lower template 5 to move up, and makes the first lower template 5 and the second lower template 6
Disengage；Finally, the second ejector retainner plate 12 stops movement, and the first ejector retainner plate 11 continues to move up, and the first thimble 13 is by vacuum extinction
Room 100 ejects from the first lower template 5, completes the demoulding, state as shown in Figure 6.
Second ejector retainner plate 12, which is moved up after a segment distance makes the first lower template 5 and the disengagement of the second lower template 6, to be needed
Stop, therefore, shifting of the limited block (not shown) to second ejector retainner plate 12 can be set in the lower mould bottom plate 8
Dynamic distance progress is spacing, and the displacement of usual second ejector retainner plate 12 is arranged to 10mm.
It is stripped using the above method, is, respectively, disengaged by four templates, can effectively weakens mold cavity to encapsulated rear true
The absorption affinity of empty arc-chutes.
Above embodiment is only the illustrative embodiments of the present invention, it is impossible to be used in limits the present invention, the present invention
Protection domain be defined by the claims.Those skilled in the art can be in the essence and protection domain of the present invention, to this
