Description
Technical Field
The utility model relates to a dry-type transformer resin pouring coil sealing strip for mould.
Background
The sealing performance of the mold is one of important technical indexes of a resin casting coil mold, and the use amount of resin, the production efficiency and the appearance quality of a product are directly influenced by the sealing performance of the mold. The poor sealing performance of the mold can cause resin leakage, on one hand, the waste of resin materials is increased, the cost is increased, the generated resin waste belongs to hazardous waste raw materials, and the post-treatment cost is high; on the other hand, the product has the defects of flash and the like, the product needs to be trimmed, and the cured resin is difficult to treat, so that the time and the labor are wasted, and resin waste and dust pollution are generated.
Disclosure of Invention
For solving the above-mentioned problem that prior art exists, the utility model provides a dry-type transformer resin pouring coil sealing strip for mould, this sealing strip structural design is reasonable, and installation simple to use is convenient and sealed effectual, and the finished product outward appearance need not reprocessing can reach operation requirement.
In order to realize the purpose of the invention, the technical proposal adopted by the utility model is as follows:
the utility model provides a dry-type transformer resin pouring coil sealing strip for mould, it includes that the preceding groove of integral type connection is followed, the back groove is followed, the base, and its cross-section is whole to be the spill, and the middle part top is provided with square groove, and preceding groove is followed, the back groove is followed narrow down wide, and the lateral surface is provided with the inclined plane, and base bottom indent is provided with the arc surface, the back groove along comparing preceding groove along high, the back groove is provided with the arch towards the recess along the cross-section top.
Furthermore, two ends of the arc surface of the base are sharp corners.
The front groove edge, the rear groove edge and the base are made of silicon rubber with temperature resistance higher than 200 ℃.
The cross section of the device is similar to a Chinese character 'concave', the front groove edge, the rear groove edge and the groove form a self-locking type sealing clamping groove structure, the bottom of the base is an elastic arc sealing structure, the length of the base can be processed into infinite length, and the corresponding length can be cut according to the use requirement.
The width of the groove can be adjusted according to the wall thickness of the die, the protrusion on the top of the rear groove is designed into an arc shape, and the arc protrusion can be supported after the die is inserted into the groove, so that the self-locking sealing effect is achieved.
The sealing strip base lower part be the design of circular arc indent, the circular arc both ends are the closed angle design, after the mould inserted the sealing strip draw-in groove, thereby because the effect of gravity or external pressure power, thereby the circular arc top atress warp laminating lower part plane and play sealed effect, and the closed angle design of both sides is laminating lower part plane more, makes the product transition after the pouring more slick and sly pleasing to the eye.
The utility model has the advantages that: compare traditional sealing strip structure, the utility model has the advantages of reasonable design, installation simple to use is convenient and sealed effectual, and product finished product outward appearance need not reprocessing and can reach the operation requirement.

1-front groove edge, 2-rear groove edge, 3-base, 4-groove, 5-arc surface, 6-protrusion, 7-thin-wall external mold and 8-mold bottom plate.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model provides a dry-type transformer resin pouring coil sealing strip for mould, it includes that the preceding groove of integral type connection is along 1, back groove along 2, base 3, and its cross-section is whole to be the spill, and the middle part top is provided with square groove 4, and preceding groove is along 1, back groove along 2 narrow down wide, and the lateral surface is provided with the inclined plane, and 3 bottom indents of base are provided with arc surface 5, the back groove compare preceding groove along 2 along 1 height, the back groove is provided with the protruding 6 towards recess 4 along 2 cross-section tops.
Furthermore, two ends of the arc surface 5 of the base are sharp corners.
The sealing strip is made of silicon rubber with temperature resistance higher than 200 ℃.
The cross section of the device is similar to a Chinese character 'concave', the front groove edge 1, the rear groove edge 2 and the groove 4 form a self-locking type sealing clamping groove structure, the bottom of the base 3 is an elastic arc sealing structure, the length of the base can be processed into infinite length, and the corresponding length can be cut according to the use requirement.
The width of the groove 4 can be adjusted according to the wall thickness of the die, the protrusion 6 at the top of the rear groove edge 2 is designed into an arc shape, and the arc protrusion 6 can be supported after the die is inserted into the groove 4, so that the self-locking sealing effect is achieved.
The utility model is used for the sealing between resin pouring coil drum formula or long cylinder formula thin wall external mold 7 and the mould bottom plate 8, a week of 7 bottoms of thin wall external mold and 8 contacts of mould bottom plate uses the sealing strip to seal, can prop circular-arc 6 after in the external mold inserts sealing strip recess 4, thereby reach from locking-type sealed effect, thereby simultaneously because gravity perhaps exerts the pressure effect outward and make sealing strip lower part circular arc warp laminating mould bottom plate 8 surfaces and play sealed effect, and laminating mould bottom plate 8 surfaces behind the both sides closed angle design atress more, make the product transition after the pouring more slick and sly pleasing to the eye.
The sealing strip is reasonable in structural design, simple, convenient and fast to install and use, good in sealing effect, and capable of meeting the use requirement without reprocessing of the appearance of a finished product.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the principles of the present invention, several improvements can be made, and these improvements should also be regarded as the protection scope of the present invention without creative work.
