必要となる。As a conventional method for molding the coil, a mold casting method is used. To explain this with reference to FIG. 2, 5 is a mold, and 5a is the mold of the mold, which represents the size of the coil of the proportional solenoid valve. 6a is a liquid resin injection port, 6b is an injection device, 8 is a seal, and 10 is a proportional solenoid valve. 7 indicates a liquid resin for coil insulation. The molding method in this case is that after inserting and fixing the proportional solenoid valve 10 into the mold 5a, the epoxy resin 7, which is a liquid resin, is applied to the coil surface using the injection device 6b.
Inject and infiltrate as in a. After that, the resin is heated together with the mold, and after the resin has hardened, the mold is released and the surface is deburred.This molding method involves: (1) Attaching the coil to the mold and sealing the gap between the mold and the coil. , Mold Clamping 9 Mixing, injection, and curing of liquid resin (2) Many steps are required for mold release and non-electrification. 2) Clamping occurs during mold clamping, and burr removal work is required.

生しにくい。The present invention solves the above-mentioned drawbacks, and as a method for molding the coil of a proportional solenoid valve, a curing agent and a thickener are mixed into epoxy resin to form a sheet, and this sheet is wrapped around the surface of the coil and heated. It is. As for the heating method, the first step is to soften the sheet-shaped resin, then heat it to the extent that the air in the coil is expelled, and even fine bubbles are expelled, and the second step is to further heat it. , the epoxy resin is cured and completely adhered to the coil. Molding part I' of the proportional electromagnetic valve manufactured by such a method has a uniform film thickness, the molding has good hardness in the outer diameter dimension, and the resin is less prone to cracking due to temperature changes.
