AI Technical Summary
Existing injection molds lack the ability to directly perceive the actual process state inside the mold cavity, resulting in a lack of dynamic information on key stages such as melt filling, pressure holding and shrinkage compensation, and cooling and shaping during the injection process. This makes real-time monitoring impossible, leading to lagging quality control and high scrap rates. In particular, the risk of batch product scrapping increases significantly in the mass production of multi-cavity gear molds.
Multiple sensors, including pressure sensors, temperature sensors, vibration sensors, and displacement sensors, are installed in the injection mold to collect pressure waveforms, temperature changes, and signals from the ejector components in the mold cavity in real time. Combined with a diagnostic module, online monitoring and intelligent diagnosis are performed to identify process deviations within the mold cavity and provide process optimization suggestions.
It enables real-time and accurate perception of the internal process status of the mold cavity, significantly improves the consistency of product size and tooth profile accuracy, reduces scrap rate, enhances mold stability and production economy, and strengthens the diagnostic capability of demolding status.
