Description

Technical Field

[0001] The utility model relates to the technical field of winding molds, in particular to a winding mold for a small reactor. Background Technique

[0002] Small air-core reactors are widely used in cabinets due to their small size and light weight. With the development of the reactor industry, the usage of small air-core reactors has increased, and at the same time, higher requirements have been put forward for the appearance of products.

[0003] In the prior art, during the winding process of a small air-core reactor, first align the aluminum bars and place them at the upper and lower ends of a cylindrical epoxy cylinder, calibrate the horizontal and verticality of the aluminum bars, and open slots at the upper and lower ends of the epoxy cylinder for fixing the aluminum bars; secondly, select a suitable tray, and sequentially place the lower aluminum bar, epoxy cylinder, and upper aluminum bar from bottom to top, and use a lead screw to pass through and fasten it to the tray; after fixing, wind glass fiber and wire on its outer surface.

[0004] However, the following problems will occur in the production method of the prior art:
