Abstract

PURPOSE:To greatly save the cost and time of manufacturing sealed molds by interposing a plate with a cavity determining the shape and position of sealing resin between an upper mold and a lower mold. CONSTITUTION:An electronic part 13 is placed between a lower mold 12 provided with a guage pin 17 and a runner 20 through which a sealing resin 24 is to be passed and an upper mold 11 provided with a pilot hole 22, a through hole 23 through which a plunger head 19 is to be passed, and a dent 26. And, a lead frame 14 with a hole through which the resin passes is interleaved and set between plates 1' and 1'' havng a pilot hole 2 of the same size as that of the pilot hole of the lead frame 14, positioned as the same place as the pilot hole of the frame 14 to seal up the resin 14, and a given shape of a cavity 3 at a position where the electronic part 13 on the lead frame 14 is sealed with the resin.
