A molding machine has a mold material supply device, a die setting device, a separating device and a deburring device. The supply device includes a mold material feeding device, an extruding device for receiving a mold material from the mold material feeding device and extruding the mold material so as to form an extruded mold material, a cutting device for cutting the extruded mold material, and a transfer device for receiving the extruded mold material from the cutting device and transferring the same. The die setting device includes a distribution plate, a first mold die, a second mold die, a third mold die, four shafts, a first mold guide fixed to one of the shafts for receiving and supporting the distribution plate, a second mold guide fixed to another shaft for receiving and supporting the first mold die, a third mold guide fixed to another shaft for receiving and supporting the second mold die, a fourth mold guide for receiving and supporting the third mold die, and means for rotating and vertically moving the four shafts together with the respective mold dies and the respective mold guides and the distribution plate, wherein the distribution plate, the first mold die, the second mold die and the third mold die are positioned in order. The separating device includes a nipping device having a plurality of fixed claws and movable claws in combination for nipping the molding products remaining in the second mold die when the fixed and movable claws are closed and releasing the molded products when the fixed and movable claws are opened.
