TEMPERATURE CONTROLLING METHOD FOR INJECTION MOLDING MACHINE

摘要

The apparatus makes easy processing of signals generated from the temperature sensors located at a plurality of positions of the injection molder, and monitoring selectively and periodically the signals so as to control the temperatures at each injection molding process. The apparatus comprises: an amplifier(50) amplifying signals generated from a plurality of sensors(J1-J5); a microprocessor(10) sequentially selecting the amplified signals, and transmitting the current temperatures in a plurality of zones to a main body; a switching circuit(20) selectively outputting the amplified values; an oscillation circuit(30) converting the amplified values into corresponding frequencies, and generating rectangular pulses proportional to the frequencies.
