Description

Technical Field

[0001] The invention belongs to the technical field of injection molding machine detection, and in particular relates to a device for detecting a touch and temperature jump at a nozzle of an injection molding machine. Background Art

[0002] Based on the working principle and working environment of the injection molding machine, a variety of situations may occur at the nozzle when it is working, but not limited to the one mentioned below. More specifically, when the injection molding machine is working, the material is heated by a high-temperature electric heating ring, and then the high-temperature liquefied material is squeezed to the nozzle through the connecting flange and sprayed into the mold for shaping.

[0003] In addition, the temperature may jump during use. When this happens, it is necessary to check whether the equipment has leakage or solidification, and make adjustments in time. In addition, the force of the nozzle when it contacts the injection position is difficult to detect and adjust. If too much force is used to push the nozzle and the injection position to contact for a long time, it may cause deformation and other damage to the injection position, thereby affecting normal production work.

[0004] Based on the above-mentioned problems, we found that it is difficult for the injection molding machine detection equipment in the prior art to avoid the above problems at the same time. Therefore, we propose a device that can simultaneously detect the contact force and temperature jump at the nozzle. Summary of the invention
