Description

Technical Field

[0001] The utility model relates to the technical field of automatic injection molding peripheral heating, in particular to an insert heating device with a temperature feedback function. Background Art

[0002] Inserts are increasingly used in processes such as injection molding and assembly. Before being placed in the mold or assembled, inserts usually need to be preheated to reach specific temperature requirements to improve the product's appearance quality and performance. However, traditional insert heating devices in the existing technology can only perform heating and cannot monitor and control the temperature during the heating process in real time, making the heating effect unstable, resulting in overheating and damage to the insert or overcooling and failing to achieve the required appearance quality and performance. Therefore, we need an insert heating device with temperature feedback function. Summary of the Invention
