Abstract

PURPOSE:To decrease the cost of a metal mold for cast and cope with the alteration of the specifications and dimensions of a molded coil easily by assembling the metal mold by upper and lower end plates, an outside wall body and a metal mold of a terminal section. CONSTITUTION:A several number of C-shaped grooves 4A-4C are formed to upper and lower end plates 1', 1, an outside wall body 6 is made up by a cylinder with the same section as the groove (4A in the figure) with dimensions proper to a coil, and a metal mold 7 of a terminal section is fixed to the opening section by means of a U-shaped metal fitting 25. The metal mold 7 of the terminal section consists of winding terminal sections 7A, 7E, connecting auxiliary sections 7B, 7D and a tap terminal section 7C, the dimensions are selected in response to the size of the coil and the metal mold 7 is fastened by means of a connecting metal fitting 11. A lower end of the coil wound on a frame in fiber reinforced plastic is fitted to a positioning member 2, the end plates 1, 1' are clamped by means of bolts 28, and a thermosetting resin liquid is injected from a spout 24 and hardened in a heating furnace.
