Embodiment 1
Fig. 2 is the structural schematic diagram of the adaptive dissipation disc insulator production technology mould therefor of charge of the present invention,
As shown in Fig. 2, in casting process, after industrial epoxy resin is mixed respectively with adaptive special type filler A and filler B, injection
It is mixed under vacuum in two pouring cans, step is respectively according to existing epoxy group alumina composite material insulating part
Industry cast requires to carry out, and is added after curing agent stirring, epoxy group filler material A composite materials are poured into mold first,
After liquid level reaches insulation zone position, capping plate is taken out, first time solidification is carried out:
Solidification 4.5 hours for the first time, then place into vacuum pouring case and vacuumize, and carrying out second in inside pours into a mould, because
It is vacuum pouring for this, without worrying that the inside has bubble, so only needing to be poured into a mould from a mouthfuls, cast, which is over, to be taken out
Come, a mouthfuls are blocked, then mold is holded up, upper auxiliary point filler can carry out secondary curing at 4 mouthfuls.
Embodiment 2
First lower half portion mold is kept flat, after placing inserts, at casting insulated area to arrow after, cover top half lid
Plate, being put into 130 DEG C of solidifications of incubator, (filler can become sticky at this time, and this makes it possible to ensure next to pour into a mould adaptive area in 4 hours
In the process, two kinds of fillers will not mixing);
Take out mold, from a mouthful the adaptive area's cast of progress (at this time should be padded 1 centimetre or so by mold at sprue gate, this
Sample can ensure not accumulate in underface after filler stream is entered and cause to block), it at a mouthfuls is poured into liquid level and rises to and cover
After the b of sprue gate, a mouthfuls are blocked with plug, mold is holded up and comes (being rotated by 90 ° counterclockwise), continues to be poured into end from b mouthfuls.
It may insure that two kinds of region fillers will not mutually melt in casting process in this way, and can guarantee the two binding site mechanical performance again.
Then mold is moved to below special material sprue gate and carries out special material cast.Special material uses asphalt mixtures modified by epoxy resin
Aliphatic radical filler material B systems, are mixed by certain proportion.Mold after cast is transferred to incubator, is carried out according to industrial requirements
It demoulds, is finally demoulded, and carry out third time solidification after secondary curing molding.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of which part may be made, belongs to the scope of protection of the present invention it
It is interior.
