The transformer resin leakage preventive rubber strip sectioning die is characterized in that the die is a plate type structure, a rubber strip groove and a sectioning knife edge are arranged on the plate type structure, and an included angle between the rubber strip groove and the sectioning knife edge ranges from 30 degrees to 60 degrees. The transformer resin leakage preventive rubber strip sectioning die has the advantages that the sectioning die is small in volume, simple in structure, convenient in use, low in cost and wide in application range, meets requirements of rubber strips with certain specifications and diameters, guarantees tight abutting of the rubber strips, is reliable in sealing property, prevents resin leaking, has appreciable economic benefit and the like.
Description
Technical field
The utility model belongs to the instrument transformer technical field, particularly relates to the anti-seepage of resin adhesive tape of a kind of instrument transformer and dissects mold.
Background technology
At present, the sealing joint strip that existing instrument transformer casting mold uses is 90 ° of butt joints, shown in the adhesive tape 5 of Fig. 4.Adhesive tape just overlap joint looks no problem, along with the assembly of mold members, a passing is arranged on the time, and this moment, adhesive tape had axial resilience, and the sealing of adhesive tape goes wrong and causes seepage of resin, and demoulding difficulty, product appearance are of poor quality.Simultaneously, mold members also has the reason of a unbalance stress when compressing adhesive tape, thereby causes the overlap joint actinal surface small slit to occur, causes the resin material to leak outside.
Summary of the invention
The utility model provides the anti-seepage of resin adhesive tape of a kind of instrument transformer to dissect mold for solving the technical problem that exists in the known technology.
The purpose of this utility model provides that a kind of to have a volume little, simple in structure, easy to use, with low cost, applied widely, satisfy different size diameter adhesive tape and use, guarantee that the sealing joint strip butt joint is tight, thereby guaranteed that the die sealing adhesive tape is tight reliable, prevented seepage of resin, can increase advantages such as considerable economic benefit for enterprise.
The adhesive tape faying surface that the utility model mold dissects changes 45 ° into by 90 °, and two positive and negative butt joints of interface have increased the sealing joint strip contact area, guarantee that contact is tight, exert pressure and the opening phenomenon also do not occur even if be subjected to external force, guarantee non-leakage resin, make full use of the adhesive tape utilization rate.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The anti-seepage of resin adhesive tape of a kind of instrument transformer is dissectd mold, and be characterized in: mold is a plank frame, the adhesive tape groove is arranged above the plank frame and dissect the edge of a knife, and the adhesive tape groove is 30 °-60 ° with dissecing edge of a knife angle.
The utility model can also adopt following technical scheme:
The anti-seepage of resin adhesive tape of described instrument transformer is dissectd mold, and be characterized in: the adhesive tape groove is 45 ° with dissecing edge of a knife angle.
The anti-seepage of resin adhesive tape of described instrument transformer is dissectd mold, is characterized in: dissecing the edge of a knife has 2-5.
The anti-seepage of resin adhesive tape of described instrument transformer is dissectd mold, and be characterized in: the adhesive tape groove has 1-3 kind size.
The anti-seepage of resin adhesive tape of described instrument transformer is dissectd mold, and be characterized in: the adhesive tape groove is arranged in parallel, and the cross section is square or circular.
The anti-seepage of resin adhesive tape of described instrument transformer is dissectd mold, and be characterized in: plank frame is the plane cuboid.
Advantage and the good effect that the utlity model has are:
The anti-seepage of resin adhesive tape of instrument transformer is dissectd mold owing to adopted the utility model brand-new technology scheme, and compared with prior art, this is a kind of being applied in the casting mold sealing device, is used to process the mold of sealing joint strip.This mold is a processing criterion mold, can dissect use simultaneously for adhesive tape with different-diameter, the principle of utilizing is that the adhesive tape cross section after guaranteeing to dissect is ellipse, angle is 45 °, two positive and negative butt joints of interface were exerted pressure and also the opening phenomenon can not occurred even if not only increased contact-making surface but also guaranteed to contact the tight external force that is subjected to.Thereby guaranteed the sealing behind the mould matched moulds.This mold has advantages such as volume is little, simple to operate, easy to use, with low cost, good in economic efficiency and applied widely.
