The specific embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
A kind of coil encapsulate mould, as shown in Figure 1, comprising: the cope match-plate pattern 1 that is arranged on the top; Be arranged on the lower bolster 3 of bottom; Also comprise the middle template 2 that is arranged on said lower bolster top, said lower bolster 3 is provided with some standing grooves and at least one locating hole; The bottom of template 2 is arranged with first mold insert 5 in said, and said first mold insert 5 is provided with groove with said standing groove correspondence position, and said lower bolster is provided with second mold insert 6 in the positive lower end of the groove of first mold insert.
Preferably, said cope match-plate pattern and said middle template are seamless link.
Preferably, said middle template and said lower bolster are fixed together through screw 8.
Preferably, also comprise guide pillar 7, said guide pillar 7 is arranged in the locating hole of said lower bolster, is connected with said middle template.
Preferably, the groove of said first mold insert top is provided with the through hole that is used for the rubber circulation.
Preferably, said second mold insert is provided with line outlet.
Preferably, be provided with the fixedly core 4 that is used for fixing coil in the said standing groove.
Fig. 2 is the vertical view of mould provided by the invention, and wherein standing groove is used to place the coil of treating encapsulate processing.Fig. 3 is the front view of lower bolster.The vertical view and the front view of template during Fig. 4, Fig. 5 are respectively.Fig. 6, Fig. 7 are respectively the vertical view and the front view of cope match-plate pattern.
Enumerate one at present and adopt mould provided by the invention that coil is carried out the concrete embodiment of encapsulate, be optimum embodiment.
A kind of coil encapsulation methods comprises: the coil that will twine rubber places the standing groove of lower bolster 3, and with fixing core 4 fixed coils, template 2 and cope match-plate pattern 1 are placed with rubber in the said cope match-plate pattern in covering; Mounted mould is put into vulcanizer to be suppressed.
Preferably, the minimum scale of the instrument of vulcanizing equipment is changed to 0.01MPa, guarantee vulcanizer pressure precisely, prevent the pressure break of coil rack.
Preferably, said rubber is fluorosioloxane rubber.
Adopt mould provided by the invention to the method that coil carries out encapsulate to be: the special (purpose) rubber at coil encapsulate place with 0.5mm twines, and then coil is placed the standing groove of lower bolster, notes the line position that of enamel-covered wire in the process of placement; Then middle template is covered; Note not being pressed onto enamel-covered wire, fixedly core installs simultaneously, and cope match-plate pattern at last closes; Simultaneously put into special (purpose) rubber, insert the vulcanizer compacting at cope match-plate pattern.
Squeeze off the problem of perhaps being discontented with at pressure hour encapsulate owing to when the coil encapsulate, through regular meeting the excessive copper cash that causes of pressure taking place, drawing through repetition test is the Pressure gauge poor sensitivity because of vulcanizing press, and pressure can not better controlled.If pressure is too small, then rubber flows slowly, and it is discontented encapsulate to occur; Pressure is bigger than normal, then can squeeze off the copper cash of shaped framework coil through the pressure transmission.The present invention draws the best pressure of coil compacting through repetition test; Manometer to vulcanizing equipment is transformed; Manometric minimum scale is changed to 0.01MPa, so effective controlled pressure, part encapsulate that suppresses and skeleton structure are all excellent; And through repetition test, part each item performance all reaches designing requirement.
Aspect sizing material; Because the designer requires sizing material can satisfy-60 ℃-200 ℃ high low temperature; And of short duration high temperature resistant 230 ℃; We adopt acrylonitrile-butadiene rubber, fluorubber, three kinds of sizing materials of fluorosioloxane rubber to suppress test respectively to this situation, and then contrast each item physical property (oil resistant, resistance to sparking, insulaion resistance), see whether it reaches designing requirement.Do resistance to sparking, insulation resistance test through chilli oil immersion, coil pairing, find that fluorosioloxane rubber can meet design requirement.
In sum: compared with prior art, the invention provides a kind of coil encapsulate mould and method, the mould that the application of the invention provides; Guaranteed the uniformity of coil dimension, and the manometer of vulcanizing equipment has been transformed, effectively controlled pressure; Avoid utilizing skeleton in the mould suppressing coil encapsulation process by the problem of pressure break and enamel-covered wire fracture; On this basis, the present invention also adopts the rubber of specific materials, makes coil after the processing reach oil resistant, prevents the effect that punctures and insulate.
