Embodiment Construction
[0034] With reference to accompanying drawing, the basic structure that the present invention implements is to adopt figure 1 As shown in the connection, the remaining parts are the same as the existing injection molding machine, and will not be described in detail here.
[0035] from figure 1 It can be seen from the figure that the control system of the injection molding machine is connected to the frequency converter and processes the signals input by the drive and detection units of the injection molding machine. These signals include the pressure and flow setting parameters related to the injection molding process, as well as the position, time, limit Bit switch and the current process section flag, as well as the operating parameters of the inverter.
[0036] Signal detection and processing includes:
[0037] The inverter is connected to the motor and the oil pump. The operating frequency of the motor in different process sections is not completely consistent. When the ...
