[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity.

[0003] During the injection molding process of the injection molding machine, it is necessary to use a temperature detection device to monitor the injection temperature in real time. In the existing injection molding machine detection device, the temperature sensor is mostly attached near the mold parting surface, which is the joint when the mold is opened and closed, and it is easy to dissipate heat. The sensor attached here can monitor whether the mold is evenly heated. However, during the injection molding process, the melt may overflow from the parting surface, forming flash attached to the sensor surface, hindering heat conduction. When processing materials such as PVC, the volatile chlorine gas will corrode the sensor surface. Long-term use is easy to affect the accuracy of the temperature sensor, and then affect the monitoring of the temperature during injection molding. Summary of the invention
