Abstract
The utility model belongs to a kind of insulation pouring mould of inductance coil, comprise interior epoxy resin cylinder, outer epoxy resin cylinder, the outside winding around of interior epoxy resin cylinder, interior epoxy resin cylinder and outer epoxy resin jacket casing connect, interior epoxy resin cylinder, outer epoxy resin cylinder are placed in bottom plate, bottom plate connects upper board by the screw rod through interior epoxy resin cylinder, and upper board end is placed on the upper surface of interior epoxy resin cylinder, outer epoxy resin cylinder, and the bolt fastening with screw rod is arranged at upper board top; Its beneficial effect is: 1) simplify manufacture craft, only needs the coiling of coil, resin-cast, solidification, does not need loaded down with trivial details die-filling technique; 2) energy-saving and environmental protection, resin employing quick-dry type adds curing agent and can solidify at normal temperatures, does not need hot setting; 3) percent defective is low, does not have loaded down with trivial details die assembly, and there is not the seepage of resin, product defect reduces greatly; 4) with short production cycle: only need 5 hours from the coiling of coil to shaped article, summer is shorter.
Description
Technical field:
The utility model relates to the inductance coil die for manufacturing such as a kind of reactor, transformer, particularly relates to a kind of insulation pouring mould of inductance coil.
Background technology:
Dry-type transformer or reactor, that to have employed the vacuum pouring of coil epoxy shaping, capacity same with it, formula transformer invaded by oil with voltage or reactor is compared, having the advantages such as lightweight, volume is little, handsome in appearance, stable performance, non-maintaining, ne-leakage is oily, the class of insulation is high, anti-moisture and soil-repellent, is substitute the first-selected product that formula transformer invaded by oil heavy at present.Transformer or reactor winding epoxy casting processing step: coil die process (beat release agent, be wound around polyester film), coiling, the outer mold that installs coil, preliminary drying, resin spice, vacuumize, pour into a mould, go out the techniques such as mould, oven dry, the demoulding, coil process; Problems existing is: 1) die-filling complexity: die surface process, coiling, die-filling, preheating, water the techniques such as resin, oven dry, the demoulding; The cleaning of vacuum tank; 2) production cycle is long: the demoulding from the coiling of coil to coil, at least needs 24h, and production capacity is limited; 3) technology difficulty is large: assembling and the cast of mould all follow the proficiency of workman to have much relations; 4) percent defective is high: if mould does not assemble, and causes the seepage of resin, and product can only by the reparation being added to product in later stage, and the product after reparation exists flaw; 5) not environmentally: cleaning die has the carcinogens such as dimethylbenzene, very large to the injury of workman; 6) not energy-conservation: mould, resin need the long heat treated of baking oven, so energy consumption is very high.
Utility model content:
The utility model provides that a kind of structure is simple, cost is low, efficiency is high, environmental protection, product percentage of head rice are high, the insulation pouring mould of energy-conservation inductance coil.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
The insulation pouring mould of inductance coil, it is characterized in that, comprise interior epoxy resin cylinder, outer epoxy resin cylinder, the outside winding around of interior epoxy resin cylinder, interior epoxy resin cylinder and outer epoxy resin jacket casing connect, and interior epoxy resin cylinder, outer epoxy resin cylinder are placed in bottom plate, and bottom plate is by screw rod, the connection upper board through interior epoxy resin cylinder, upper board end is placed on the upper surface of interior epoxy resin cylinder, outer epoxy resin cylinder, and the bolt fastening with screw rod is arranged at upper board top.
Wherein, be provided with rubber blanket between bottom plate and interior epoxy resin cylinder, outer epoxy resin cylinder, rubber blanket and the outer outer field junction of epoxy resin cylinder scribble fluid sealant.
Wherein, bottom plate is a tabular, and upper board is starlike or criss-cross stripe board.
On epoxy cylinder coiling, outer for coil epoxy jacket casing be contained in be fixed on the good coil of coiling, coil and inside and outside epoxy cylinder bottom and seal, vacuumize in vacuum equipment, pour into a mould, depanning, oven dry.
The beneficial effects of the utility model are: 1) simplify manufacture craft, only need the coiling of coil, resin-cast, solidification, do not need loaded down with trivial details die-filling technique; 2) energy-saving and environmental protection, resin employing quick-dry type adds curing agent and can solidify at normal temperatures, does not need hot setting; 3) percent defective is low, does not have loaded down with trivial details die assembly, and there is not the seepage of resin, product defect reduces greatly; 4) with short production cycle: only need 5 hours from the coiling of coil to shaped article, summer is shorter.
