The invention relates to an electromagnetic valve pilot head and a preparation method of a movable iron core sealing component thereof. The electromagnetic valve pilot head comprises a spacer sleeve,a static iron core and a movable iron core which are arranged in the spacer sleeve, the electromagnetic valve pilot head is characterized in that holes are formed in the front end face and the rear end face of the movable iron core, and rubber sealing cores are poured and molded in the holes through a vulcanization method. The structure of the movable iron core is improved, holes are formed in thefront end face and the rear end face of the movable iron core, and rubber sealing cores are poured and formed in the holes by the vulcanization method, so that a cavity and two springs in the traditional movable iron core structure are omitted, the structure is greatly simplified, and parts are reduced; during processing, a large number of batch valve cores can be installed in a mold, rubber is poured and then flattened b
