A pressure molding machine for molding various types of stepped articles having, a nest of ram adapters receiving thereon pressure rams and a common base support having cylindrical walls positioned coaxially. The end faces of the walls are at the same level for receiving thereon base ends of the ram adapters, and a nest of movable frames each operated by a pressure cylinder. The movable frames move along guide channels provided in the cylindrical walls of the common base support for operating the ram adapters. Total length and total weight of the machine can be minimized, a die-set is easy for manufacturing, mounting and exchanging, and costs for the equipment can also be minimized.
