METHOD AND APPARATUS FOR SETTING TEMPERATURE OF HEATING CYLINDER IN INJECTION MOLDING MACHINE

摘要

PROBLEM TO BE SOLVED: To collectively set the set control temp. of a specific control temp setting device and that of other control temp. setting device so as to provide temp. difference between them. SOLUTION: Alteration temp., for example, A deg.C is set to an altereation temp. setting device 62 and an operation value (subtraction temp.), for example, B deg.C is set to an operation value setting device 63 and an execution key is pushed. Whereupon, the set control temps. up to now of the control temp. setting devices 40-48 of a heater spaced apart from a hopper are altered and set to A deg.C and the set control temp. of the control temp. setting device 49 of the heater in the vicinity of the hopper is collectively altered and set to (A-B) deg.C, that is, temp. lower than the alteration temp. A deg.C of the other control temp. setting devices 40-48 by B deg.C.
