Front panel of transformer coil casting die and fabrication method thereof

Abstract

The invention discloses a front panel of a transformer coil casting die and a fabrication method thereof. The front panel of the transformer coil casting die comprises a base plate, a plurality of side plates and a wiring post casting die, wherein the plurality of side plates encircles the base plate, two adjacent side plates are connected, the base plate is provided with an installation hole communicated with an inner cavity of the coil casting die, the wiring post casting die is fixed in the installation hole and provided with a casting opening communicated with the inner cavity of the coil casting die, and the side plates are provided with fixed holes. By the front panel, each plate is unnecessarily processed such as turning, milling and the like, an appropriate-thickness plate is only selected to be processed, the fabrication process is simplified, moreover, an expensive steel channel is prevented from being used as a raw material, quality requirement can be reached by adopting an ordinary steel plate which has high strength and is difficult to get rusty, and fabrication cost is effectively reduced.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a front panel of a transformer coil casting mold and a manufacturing method thereof. Background technique [0002] The front panel of the transformer coil casting mold is mainly used for casting and molding of the terminal posts on the coil during casting, and together with the casting outer mold and the casting bottom plate, it constitutes the coil casting mold. In the process of casting dry-type transformer coils, due to the different heights of the coils and the different positions of the terminal posts, the coil casting molds need to be prepared with corresponding front panels, so the number of front panels required is large, and many special products or output are extremely high Few products have a specific design on the front panels, which are difficult to use for other products, so they become invalid after use. Moreover, the existing pouring front panel is relatively difficul...

Problems solved by technology

In the process of casting dry-type transformer coils, due to the different heights of the coils and the different positions of the terminal posts, the coil casting molds need to be prepared with corresponding front panels, so the number of front panels required is large, and many special products or output are extremely high The front panels of few products are all of specific design, it is difficult to be used by other products, so they become invalid after use

Moreover, the existing pouring front panel is difficult to process and the cost is high, which seriously increases the manufacturing cost of the transformer
