Abstract
The invention discloses an epoxy resin pressure gel forming machine which comprises a movable rack, a heating plate (4) assembled on the rack and an open-close type mould (8) assembled on the heating plate, wherein an ejecting mechanism capable of withdrawing a voltage transformer blank body (9) in the mould is arranged on the rack, the mould is connected with a vacuum stirring tank (6) through a gel injecting hole (5) and a gel injecting pipe (7), and gel is injected into the mould by the vacuum stirring tank when the vacuum pressure is 8kg/cm<3> (about 0.8MPa). Compared with an existing epoxy resin pressure gel forming device, the epoxy resin pressure gel forming machine disclosed by the invention has the advantages that the machine is compact in structure, small in floor space, and convenient to operate; the machine is quick to heat, short in heating time, and short in curing time, so that the manufacture efficiency can be improved; a set of mould can be recycled, so that the manufacture cost of the mould can be saved, and the cost can be reduced; and the gel is convenient to inject, and the mould is convenient to open, so that the machine is small in labor intensity, and environment-friendly in working environment.
Description
Technical field
The present invention relates to pressure forming machine, especially relate to a kind of epoxy resin pressure gel-forming machine.
Background technology
Voltage transformer generally is comprised of coil, iron core and insulating barrier, and insulating barrier (housing) mostly adopts the poured with epoxy resin curing molding.During manufacturing, first fully stir in vacuum tank with epoxy resin and form epoxide-resin glue, to the stent putting of coil etc. be housed in the cylinder tank body of heating, again epoxy resin gel is injected in mould, after mould is heated epoxy resin gel is solidified, shift out cooling rear die sinking in the cylinder tank body and can be made into voltage transformer.But there is following problem in this manufacture method: the one, and the mould warm-up time that is deposited in a tank body is long, causes the gel solidification time long, makes efficient low; The 2nd, injecting glue and die sinking inconvenient operation, working environment is not very good; Be to need many mold turnovers to support the use again, the mould manufacturing expense is high.
Summary of the invention
Existing problem when making for voltage transformer in above-mentioned prior art the invention provides a kind of not only hardening time short, makes efficient high, and easy to operate, the epoxy resin pressure gel-forming machine that the manufacturing cost expense is low.
The technical scheme that the technical problem to be solved in the present invention is taked is: described epoxy resin pressure gel-forming machine comprises frame and is fitted in the heating plate on frame and is fitted in retractable die on heating plate, be provided with the ejecting mechanism that the voltage transformer base substrate in mould can be taken out on described frame, described mould is connected with the vacuum stirring tank with injected rubber hose by hole for injecting glue.
The course of work of the present invention is: at many vacuum stirring tanks of correct position configuration, epoxy resin is joined in tank body, extract tank body out vacuum, tank body stirs under vacuum and makes epoxy resin form gel, the vacuum stirring tank is moved to pressure forming machine one side successively, be about 0.8MPa at 8kg/cm3() gel is injected mould under vacuum pressure, solidify at 150-200 ℃ of temperature and can start cylinder in 1 hour, beat and change mould taking-up voltage transformer base substrate and put into that correct position is cooling to be got final product.
Epoxy resin pressure gel-forming machine of the present invention is compared with existing epoxy resin pressure gel shaped device: the one, and compact conformation, floor space are little, easy to operate; The 2nd, quick heating, heat time heating time is short, and shorten hardening time, makes efficient and improve; Three is that a mold can be recycled, and has saved the mould manufacturing expense, has reduced cost; Be that injecting glue and die sinking are all very convenient again, labour intensity is little, good work environment.
