Abstract

PURPOSE:To increase the efficiency of manufacturing a thin coil by disposing a sole coil formed by bundling a plurality of wires in the prescribed array in a plurality of flat plates, containing them in a mold, filling under pressure resin from the inside of the coil, and integrally forming it. CONSTITUTION:A sole coil 1 in which a plurality of wires are bundled is disposed in a plurality of arrays, and a shaft 4 is contained in a space between a lower mold C and a middle mold B. Then, melted epoxy resin is filled under pressure in a press mold A from a plurality of inlets 14 disposed at the inner periphery of the coil 1, cooled, and the coil 1 and the shaft 4 integrated with resin are removed. Since the inlets 14 are provided at the inside of the coil, gas is exhausted to the outer periphery, thereby eliminating the damage of the shaft and the removal of the shaft. Thus, the manufacture of the coil can be efficiently performed.

In FIGS. 3 and 4, A is a push die, B is an upper die, and C is a 4-lower die. The mold B is a plurality of resin discharge ports provided in the stopper mold B, and the resin discharge port # is located at a position facing the center side of the armature coil (2). The above-mentioned armature coil was installed in a mold having such a configuration as shown in FIG. Notoshi started injection from the outlet well within a few seconds,
After dispensing the resin, hold the curing time for several minutes, and then remove the armature coil.
The two are integrally molded. At this time, the resin 4 flows uniformly from the center to the outer periphery because a plurality of discharge ports are provided in the center.

Therefore, unlike conventional methods, there is no damage to the shaft or the shaft cannot be pulled out, and since there are multiple discharge ports, the resin flows quickly and is uniformly dispersed, resulting in deformation of the armature coil. In addition, it has excellent effects such as smooth shaping of the flat surface.
