Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a thermocouple special for molds. Background Art

[0002] Thermocouples used in the mold industry are generally composed of a wire connected to a temperature probe. In order to increase the connection strength between the wire and the temperature probe, after the ends of the wire and the temperature probe are connected, a protective layer can be set outside the connection through a press process to protect the connection from failure. However, since the temperature probe is a circular structure, the rubber head attached to the outer layer is difficult to maintain circumferential stability for a long time and is easy to rotate; the surface of the wire is very smooth and it is easier to slip out of the rubber head. In addition, if the injection pressure is too high when pressing the rubber head, it is easy to cause the connection to break. Utility Model Content
