Problems solved by technology

[0002] The hot runner of the injection mold is installed between the mold back plate and the a-plate. After the glue leaks, the employees cannot observe it. With the increase of the glue leakage, the leaked material in the hot runner will accumulate more and more, causing large-scale damage to the hot runner; currently in this industry In China, no such technology has been found to detect and alarm hot runner glue leakage; in order to reduce the damage of glue leakage to other parts of the hot runner, reduce economic losses, and achieve preventive maintenance, this detection and alarm device is designed
[0003] At present, the commonly used methods for detecting glue leakage in hot runners are: maintenance personnel disassemble the back plate for inspection and use a multimeter to detect, the detection is cumbersome, the efficiency is low, and the maintenance cost is high.

Abstract

The invention provides a mold hot runner gum leakage automatic detection system. The mold hot runner gum leakage automatic detection system comprises an alarming device, a detection unit and a power supply control unit, wherein the alarming device and the detection unit are both electrically connected with the power supply control unit; the power supply control unit comprises a power supply and a relay; the alarming device is an alarming bell or an alarming lamp; the detection unit comprises an induction contact sheet, a spacing switch and a manual switch; the alarming device and a contact of the replay are connectd to two ends of the power supply in series; the spacing switch, the manual switch and a coil of the relay are connected to two ends of the power supply in series. The mold hot runner gum leakage automatic detection system provided by the invention can automatically detect the mold hot runner gum leakage situation for the first time and can detect a hot runner in production for a long time, and the off-machine point detection time is shortened; the situation of large-area damage of the hot runner due to difficulty in finding out the gum leakage of the mold hot runner is avoided, and the maintaining cost is greatly reduced.
