Zusammenfassung:	PURPOSE:To reduce the temperature lowering and enhance the heat efficiency and obtain a high quality product by heating the heater embedded in the die block moving between the extruding position and the outside position from the machine and insulating at the time of changing the die while holding the die through the die cassette. CONSTITUTION:A die is changed by moving a die block 24 holding dies 26 through a die cassette 25 and being supported with a die slide 22 between a waiting position outside machine and a using position inside machine. A heater 29 embedded in this die block nearby to this die cassette, and plural pieces of moving coupler 30 supported with the die block and connected to this heater are provided. The fixed coupler 32 connected with an electric power source and connected to the each moving coupler by being driven back and forth with a driving device arranged respectively near the outside machine waiting position and the inside machine using position of the die block corresponding to the moving position of each moving coupler are provided. Therefore, because the die block can be heated and insulated even if it is on the outside of machine, the heat efficiency is improved and the high quality product can be obtained.
