[0002] High-frequency induction heating is a way to use electromagnetic induction to heat electrical conductors, generally metals, which will generate eddy currents in the metal, causing Joule heating of the metal due to resistance, and the heating effect of the high-frequency induction coil mainly depends on the induction coil In addition, it is also directly related to factors such as the shape, number of turns, and pitch of the induction coil. To make the most effective use of the power of the equipment, the induction coil should be designed reasonably according to the material and shape of the workpiece. It is very important that the existing high-frequency induction coils are mostly hand-wound during production, and there are situations such as inaccurate coil shape, different diameters of coil turns, uneven distribution of turn pitch, and easy deformation of the induction coil.

[0003] In order to solve the above problems, Publication No. CN110246683A discloses a mold for making induction coils and a method for making coils, which includes a plurality of diameter adjustment discs arranged sequentially from top to bottom, and there are useful For the column for adjusting the turn pitch, the invention uses a diameter adjusting disc to ensure the inner diameter of each turn of the coil and the number of turns of the coil, uses a column to ensure the distance between each turn of the coil, and injects fine sand to ensure that the coil No deformation occurs, and the copper tube is softened by heating to reduce the difficulty of winding. However, this invention does not have a cooling device. Since the temperature of the induction coil after winding is still high, if the natural cooling and shaping method is adopted, it will take a long time and is easy to drag. The production progress of the slow induction coil, if cooling water is passed through the coil for cooling, it is necessary to remove the coil which is still in a softened state from the mold, pour out the fine sand in the copper tube, and then pass cooling water etc. for cooling , in this process, the coil is easily deformed by force, and there are pits and protrusions, which affect the subsequent use of the coil. If the cooling medium is directly sprayed on the coil, it is necessary for the staff to hold the sprinkler head for mobile spraying, which is time-consuming and laborious. , and prone to uneven cooling
