Zusammenfassung:	PURPOSE:To provide an automatic molding system in which the efficiency of housing of the disposal box for generated unnecessary substance and the safety in a recovery operation are improved in an automatic molding system in which the lead frame, whereon the molded material formed in the previous process is mounted on a resin package, and an unnecessary part are separated. CONSTITUTION:A cull sucking part 12, with which a plurality of runners 22 are integrally supported in a molded article, and a plurality of sets of small units, which perform a gate breaking operation to separate a resin package- mounted lead frame from the runners 22, are provided on a substrate. Besides, runner breaking plates 13 are provided on the substrate in such a manner that they cross the put in the vicinity of the boundary of the cull 21 and the plurality of runners 22. As a result, the runners 22 are cut from the cull 21 simultaneously with the gate breaking operation.
