Tin soldering die for choke coil

The invention relates to the technical field of auxiliary devices for tin soldering for coils, and discloses a tin soldering die for a choke coil. The tin soldering die for the choke coil comprises aheat-resistant steel plate, wherein a bolt hole is formed in one side of the top of the heat-resistant steel plate; a bolt sleeves into the bolt hole through a thread; and a groove is formed in one side of the top of the heat-resistant steel plate. According to the tin soldering die for the choke coil, through the cooperative arrangement among the heat-resistant steel plate, the bolt hole, the bolt and a soft magnet, between the heat-resistant steel plate and the soft magnet, the soft magnet is rapid and stable in installation; moreover, through use for rubber and magnetic powder, the soft magnet is durable in use, the service life is prolonged, and the case that cracks are easily generated and then breakage is caused due to a brittle material of a rigid magnet; and moreover, through use for the material, the magn
