A kind of parameter monitoring method in injection molding process

Abstract

The invention discloses a parameter monitoring method in an injection molding process. The method comprises the following steps of S1, regulating the injection molding force of an injection molding machine so that melt in the injection molding machine is in a preset flow rate range; S2, obtaining a real-time injection molding force of the injection molding machine; judging whether the real-time injection molding force of the injection molding machine is greater than a preset injection molding force threshold value or not; when the judging result is yes, executing S3; otherwise, executing S4; S3, performing temperature rise on an injection molding mold; obtaining real-time temperature of the injection molding mold; judging whether the real-time temperature of the injection molding mold is greater than a preset temperature threshold value or not; when the judging result is yes, giving out warning; S4, collecting a multi-view-angle image of the injection molding mold; judging whether theinjection molding mold is tightly locked or not according to the multi-view-angle image of the injection molding mold; when the judging result is no, increasing a mold locking force of the injection molding machine; S5, obtaining the real-time mold locking force of the injection molding machine; judging whether the real-time mold locking force of the injection molding machine is greater than a preset mold locking force threshold value or not; if the judging result is yes, giving out warning notification.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a parameter monitoring method in the injection molding process. Background technique [0002] With the increasing abundance of plastic products, the technological requirements for injection molding processing are also increasing. It is necessary to adjust the injection molding process parameters such as injection force, melt flow rate, mold temperature, and clamping force of the injection molding machine to ensure the molding of the product. The precision meets the processing requirements. [0003] At present, in the production process of injection molding machines, skilled technicians usually use memory, reference or intuition to set the original process parameters on the injection molding machine, and the technicians gradually optimize and fine-tune the injection molding process parameters. This processing method is not only time-consuming, laborious, and material-in...

Problems solved by technology

This processing method is not only time-consuming, laborious, and material-intensive, but also difficult to effectively manage process parameters due to changes in technical personnel; when the environmental parameters of production and processing (such as ambient temperature, ambient humidity, ambient air pollution index, etc.) are different, The corresponding injection molding process parameters that meet the processing requirements will also change accordingly, but changes in these environmental parameters are often easily overlooked by technicians, and it is difficult for technicians to intuitively make more accurate quantitative references to environmental parameters, thus affecting technicians.
