Abstract
The invention belongs to the field of injection molding machines and discloses a charging barrel temperature control method with a warning function for an injection molding machine. The charging barrel temperature control method with the warning function for the injection molding machine comprises the following steps that (1) the current actual temperature values of all sections of a charging barrel are acquired through temperature sensors and sent to corresponding proportion-integration-differentiation (PID) control modules; (2) calculation programs are arranged in the PID control modules, so that temperature control error values of all the sections of the charging barrel are obtained; and (3) the original control output values of electric heaters of the corresponding sections of the charging barrel are calculated through the PID control modules. The temperatures of all the sections of the charging barrel are measured, and an alarm is given when the measure values exceed preset values; when the temperature difference between two adjacent sections of the charging barrel exceeds 10 DEG C, an alarm is given. According to the charging barrel temperature control method, PID control-output calculation of all the sections of the charging barrel is conducted, then actual control output is obtained through a uniform synchronization algorithm module. In addition, temperature measurement is conducted on each section of the charging barrel independently, alarms are given, and thus safety is improved. Furthermore, every two adjacent sections of the charging barrel are compared independently, and thus the temperature is prevented from being increased too rapidly.
