PROBLEM TO BE SOLVED: To provide an inexpensive temperature adjuster of a downward part of a hopper. SOLUTION: The temperature adjuster has a temperature adjuster main body 20 connected to a cooling hole 9 mounted in a temperature adjusting portion 5 of the downward part of the hopper via a pipe 10. The temperature adjuster main body 20 has the tank 21 of a cooling medium, a pump 22, a radiator 23, and a fan 24 driven by a motor 25 to send cool wind to the radiator 23. The cooling medium is circulated between the temperature adjusting portion 5 of the downward part of the hopper and the temperature adjuster main body 20 by driving the pump 22. A temperature sensor 8 is mounted in the temperature adjusting portion 5 of the downward part of the hopper. If the temperature detected by the sensor 8 is higher than the set temperature, the controller 30 controlling an injection molding machine cools the cooling medium circulated by the fan to conduct the feed back control of the temperature of the temperature adjusting portion 5 of the downward part of the hopper. Since the controller 30 controlling the injection molding machine also controls the temperature adjuster main body 20, it can be inexpensively achieved. COPYRIGHT: (C)2005,JPO&NCIPI
