[0002] At present, in the automatic embedding device of the injection molding machine mold, robots are usually used to perform the automatic embedding operation. This approach relies on the precise operation of the robot to ensure the accuracy of each embedding. However, this method has certain risks, because it relies on the accuracy of the robot to ensure the accuracy of the embedding, and it is easy to have embedding abnormalities. This abnormality may come from multiple factors, including robot accuracy problems-wear of the mold or injection molding machine-quality changes of raw materials, etc. Since the operation of the automatic embedding device of the mold requires a high degree of precision and stability, abnormal situations may cause production line shutdowns-product quality degradation and waste of resources. For this reason, we propose the ELP insert floating clamp mechanism. Utility Model Content
