Abstract
PURPOSE:To prevent displacement in a molding die in the resin molding of long or continuous lead frames by preheating the lead frames to a molding temperature. CONSTITUTION:Lead frame assemblies are conveyed in between an upper molding die 9 and a lower molding die 10 along guide rails 12. The lead frames are heated to a temperature near a molding temperature by heaters 13 contained in the guide rails, then the lower molding die rises and pilot pins 20 are inserted into the pilot holes of the lead frames together with the guide rails thus fixing the lead frames. Since the lead frames have been heated, they have been thermally expanded and accordingly, displacement in the molding die is prevented.
