Abstract

A method and a device for monitoring the angle ejection mechanism of an injection mold relate to an injection mold. Through strain, pressure and temperature real-time measurement methods, the state of the angle ejection mechanism during movement is monitored, and state change information of the angle ejector during movement is acquired. Optical fiber strain sensors and wireless strain sensors are selected and used in the strain monitoring method. Wireless strain force sensors are selected and used in the pressure monitoring method. An optical fiber temperature sensor is selected and used in the temperature monitoring method. The strain sensors are respectively arranged on an angle ejector rod, an ejector retainer plate and an angle ejector slide. The force sensors are arranged between a support plate and a guide block. The temperature sensor is arranged around the angle ejector rod. State parameters of the angle ejector during movement can be collected in real time and processed. The real-time state of the angle ejector can be judged. When the state of the angle ejector changes suddenly or is abnormal, the monitoring system can immediately give an alarm in the production site, and production can be stopped immediately to prevent the angle ejector from being damaged.

Description

technical field [0001] The invention relates to an injection mold, in particular to a method and a device for monitoring a tilting mechanism of an injection mold. Background technique [0002] The inclined top mechanism is one of the important parts of the injection mold design. It is mainly used to form the side protrusions and side holes inside or outside the product. Because it is compatible with the dual functions of the withdrawal mechanism and the inlay mechanism, the inclined top mechanism is used in injection molding. The application of molds is also becoming more and more extensive, especially as the dimensional accuracy and appearance of electrical products are getting higher and higher, the role of the tilting mechanism in product injection molding is becoming more and more important. [0003] At present, in the injection molding industry, in the process of producing injection molding parts, due to uncertain factors such as abnormal tightening force, fluctuation o...
