Abstract

The invention relates to a method for casting a transformer coil and a special mold, and belongs to the technical field of transformer production. The technical scheme is that the special mold comprises a cross (1), an upper end plate (2), an upper locating plate (3), an internal mold (5), an external mold (6), a lower locating plate (7), and a lower end plate (8); the lower locating plate is connected with the lower end plate; an elongating part of the upper locating plate is connected with the upper end plate; the internal mold is placed between the upper locating plate and the lower locating plate; the internal mold is connected with the upper end plate and the lower end plate by a screw; the external mold is arranged vertically parallel to the internal mold; the external mold is impacted and connected with the cross and the lower end plate by a screw. The positive effect of the invention is that when the internal and the external diameters are the same, the axial direction of the coil can be adjusted, which is in favor of the generality of the mold. In addition, the structure is simple, and the processing is easy, which can save materials and processing cost required by the mold, and reduce the manufacturing cost of the mold.

Description

technical field [0001] The invention relates to a method for casting transformer coils and a special mold, belonging to the technical field of transformer production. Background technique [0002] At present, most of the cast transformer coil mold structures are made of thick steel plates rolled and welded by the inner mold. The existing problems are: long processing cycle, high cost, and the height cannot be adjusted, and the versatility is not strong. Contents of the invention [0003] The purpose of the present invention is to provide a method for casting transformer coils and a special mold, which can reduce the cost of mold manufacturing, make the mold have certain versatility, and solve the above-mentioned problems in the background technology. [0004] Technical scheme of the present invention is: [0005] A special mold for casting transformer coils, including a cross, an upper end plate, an upper positioning plate, an inner mold, an outer mold, a lower positionin...
