[0011] The second aspect of the utility model also provides a mold for enameled wire coating comprising the paint tank device.

[0012] Preferably, the mold further comprises a mold guide rail, a second coating medium arranged above and opposite to the first coating medium, a pressing block arranged on the upper surface of the second coating medium, and the second coating medium and the pressing block being fixed on the mold guide rail. The coating medium arranged oppositely upwards and downwards coats the surface of the wire, and the pressing block applies pressure, so that the coating film is more uniform and consistent, and the wire can also be polished to a certain extent.

[0013] Preferably, the pressing block is fixed on the mold guide rail through a pressure adjusting screw, and the contact pressure of the pressing block and the second coating medium is adjusted by tightening or loosening the pressure adjusting screw, so that the structure is simple and easy to adjust.

[0014] Further preferably, the pressure adjusting screw is equipped with a compression spring to maintain a constant pressure applied to the pressing block through elastic coupling.
