Abstract
The present invention offers a technique for providing assistance in setting at least one of the temperature of a nozzle and the temperature of a cylinder. A control device for an injection molding machine includes a monitoring part configured to monitor, during a filling step of filling the inside of a mold device with a molding material, a change in the filling pressure acting on the molding material.
Claims12
A control device for an injection molding machine, the control device comprising:
- processing circuitry configured to monitor, during a filling step of filling an inside of a mold device with a molding material, a change in a filling pressure acting on the molding material,
- wherein the processing circuitry is configured to monitor, as the change in the filling pressure, at least one of whether the filling pressure peaks when a foremost position of the molding material is forced out of a nozzle provided at a tip of a cylinder to inject the molding material into the mold device or whether there is a pulsation of the filling pressure, the pulsation being recurring small peaks and small valleys of the filling pressure, during the filling step.
A method of controlling an injection molding machine, the method comprising monitoring, during a filling step of filling an inside of a mold device with a molding material, a change in a filling pressure acting on the molding material,
- wherein said monitoring monitors, as the change in the filling pressure, at least one of whether the filling pressure peaks when a foremost position of the molding material is forced out of a nozzle provided at a tip of a cylinder to inject the molding material into the mold device or whether there is a pulsation of the filling pressure, the pulsation being recurring small peaks and small valleys of the filling pressure, during the filling step.
