A mold structure for installing copper nuts on insulating seats

The invention discloses a die structure for mounting a copper nut on an insulating base. The die structure comprises a front die core and a back die core. A mounting column is arranged on the front die core, the copper nut is arranged on the mounting column in a sleeving manner, a forming hole and a mounting cavity are formed in the back die core, an elastic column and an elastic cover are movablyarranged in the mounting cavity, one end of the elastic cover stretches into the forming hole and a through hole where the elastic column stretches into is formed in the elastic cover, and a cushioncover is further arranged between the elastic column and the elastic cover. When the front die core and the back die core are assembled, the mounting column and the copper nut stretch into the forminghole, a forming space where an injection medium flows into is formed between the copper nut and the inner wall of the forming hole, an eject force of the elastic cover is greater than frictional force generated by the injection medium to the copper nut in the forming space during injection molding, and the eject force of the elastic cover and the eject force of the elastic column are smaller thanpressure generated by the injection medium in the forming hole to the elastic cover during injection molding. The die structure is simple in structure and good in injection molding effect, the injection molding success rate of the insulating base is high, and meanwhile, the effective thread length of the copper nut is prolonged.
