Problems solved by technology
[0006] For epoxy resin casting dry-type transformer casting molds, in order to reduce transformer manufacturing costs, improve production capacity and efficiency, enterprises omit the use of upper end caps in the mold, resulting in liquid epoxy resin in the casting process due to the lack of upper end caps and lower end faces. Its extrusion makes the final epoxy resin molded on the transformer not tight
In addition, during the casting process of the mold lacking the upper end cover, it is difficult to prevent the surrounding impurities from entering the liquid epoxy resin, thereby affecting the casting effect
Also, the lack of a mold for the upper end cap resulted in an uneven top surface of the epoxy molded on the transformer

The invention discloses an epoxy pouring mold with adjustable pouring height and an inner mold that is easy to fall off. The top of the long threaded rod installed on the bottom plate is inserted into the first through hole of the pressing piece, and the long threaded rod is screwed to clamp the upper nut and the lower nut of the pressing piece. The top of the short threaded rod screwed on the upper end cover is inserted into the second through hole of the pressing piece, and the short threaded rod is screwed to clamp the upper nut and the lower nut of the pressing piece. The height of the upper end cover can be adjusted arbitrarily by adjusting the height of the upper end cover with the short thread rod when the above-mentioned long threaded rod lifts the pressing part, so as to meet the epoxy resin pouring height of various transformers. The inner mold is formed by winding a plate into a cylindrical shape, and there is a certain gap between two ends of the plate. After pouring, the staff can easily remove the short threaded rod to remove the attachments on it, and can easily separate the inner mold from the finished product.
Description
[0001] Technical field: [0002] The invention relates to the technical field of transformers, in particular to an epoxy casting mold. [0003] Background technique: [0004] At present, the demand for large-capacity epoxy resin cast dry-type transformers in the power equipment market is increasing. Known large-capacity epoxy resin pouring dry-type transformer with hard mold. With the continuous improvement of the manufacturing level and production capacity of resin cast dry-type transformers in enterprises, the traditional hard casting molds for resin cast dry-type transformer coils are no longer suitable for the production and manufacture of large-capacity epoxy resin cast dry-type transformer high-voltage coils. High requirements, long manufacturing and processing cycle, high cost, large land occupation and other issues have become a major bottleneck affecting various transformer manufacturing enterprises to reduce costs, increase production capacity and benefit. [0005] ...
