PURPOSE:To provide the heat recovering system for an extrusion molder, with which the heat generated from the extrusion molder is recovered so as to make the molding conditions and working environments in a factory, in which the extrusion molder is arranged, agreeable. CONSTITUTION:To an extrusion molder 10 consisting of a heating cylinder 11, a screw 12, with which resin in the heating cylinder 11 is kneaded, melted and fed out of the cylinder, a screw driving part 13 and a die 16, which is connected with the heating cylinder 11, heat insulating covers 2 and 3 are arranged at least onto the outer surface of the heating cylinder 11 and around and near the side peripheral surface of the die 16 so as to connect ducts 4 and 5, which communicate with the atmospheres inside the heat insulating covers 4 and 5, with the heat insulating covers 4 and 5 so as to constitute a system, which forcibly circulate the inside-cover atmosphere through the ducts 4 and 5. |
