PURPOSE: A device to supply heat of an injection blow molding machine is provided to fundamentally solve problems such as scale generated in a circulation line and an oil leak as heat medium oil is not used and to reduce costs required to clean the circulation line of the heat medium oil and to maintain an oil temperature control device. CONSTITUTION: An injection blow molding machine comprises a first mold, a second mold (20), and a third mold. The second mold includes a plurality of stick-shaped heaters (21), a core (25), a plate (23), a plate-shaped heater (27), and a temperature controller. A plurality of holes through which the stick-shaped heaters pass is formed in the plate to insert the stick-shaped heater into an inner side and an air supply path is formed in an inner side to supply air to the core. The plate-shaped heater is connected to the outside of the plate, receives the air from the outside, and supplies the heated air to a supply path of the plate. The core and the plate are heated by generating the heat through the stick-shaped heater and the plate-shaped heater without medium oil or medium water. |
