[0002] Plastic injection molds are one of the key equipment for manufacturing plastic products. In order to meet the needs of different types of plastics, injection molds usually need to have a multifunctional cooling system to effectively control the temperature during the injection process. The function and stability of the cooling system directly affect the performance and production efficiency of the injection mold.

[0003] During the plastic injection molding process, after the plastic material is heated to a molten state, it needs to be quickly cooled and solidified through a cooling system to ensure product quality and production efficiency. However, a failure in the cooling system may lead to serious production problems. When the cooling system fails or works unstably, the mold temperature cannot be effectively controlled.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] like Figures 1 to 3 The fault monitoring system of the plastic injection mold cooling system shown comprises:

[0035] Sensor module, to obtain the pressure, temperature and flow information in the cooling pipe;

[0036] The control module analyzes and processes the acquired data and controls the system;

[0037] An alarm module sends out an alarm signal;

[0038] The sensor module is installed inside the cooling pipe, the output end of the sensor module is connected to the input end of the control module, the first output end of the control module is connected to the input end of the alarm module, and the second output end of the control module is connected to the control device of the cooling system.

[0039] As the core part of the fault monitoring system, the sensor module is responsible for collecting the pressure, temperature and flow information inside the cooling pipe in real time. These data are key indicators of the working status of the cooling system and can intuitively reflect the cooling effect and the flow status of the pipe; the control module is the key link for processing and analyzing these data. It can judge whether the cooling system is working normally based on the data provided by the sensor module. If there is an abnormality, such as excessive temperature or abnormal flow, the control module can timely analyze the data and make corresponding control adjustments. When the control module detects a fault or abnormality in the cooling system, the alarm module can send an alarm signal to remind the operator to take countermeasures to avoid possible production problems and safety risks. This system can not only monitor the working status of the cooling system in real time, but also give an alarm in time when a fault or abnormality occurs, which helps to improve the quality and efficiency of injection molding production and reduce losses and risks in production.

[0040] As a preferred embodiment of the above, Figure 1 As shown, the control module includes:

[0041] The central controller makes judgments on the information received and makes adjustments based on system feedback;

[0042] PID controller, to adjust and correct the system;

[0043] The input end of the central controller is the input end of the control module, the first output end of the central controller is connected to the input end of the PID controller, the second output end of the central controller is the first output end of the control module, and the output end of the PID controller is the second output end of the control module.

[0044] The central controller is mainly responsible for monitoring and judging the system. It receives information from the sensor module and analyzes and judges according to the preset algorithm and logic to determine whether the cooling system is in normal working condition. The PID controller is responsible for the actual system adjustment and correction, and can make precise adjustments according to the feedback signal of the system to ensure that the system can quickly and accurately return to a stable state. For example, when an abnormal situation is found, such as excessive temperature or abnormal flow, the central controller can quickly make a judgment and pass the judged signal to the PID controller. The PID controller sends the adjusted control signal to the control device of the cooling system to achieve precise control of the cooling system. Through the synergy of the central controller and the PID controller, the control module can respond and adjust the working state of the cooling system in a timely manner to ensure that it is always in the best state throughout the injection molding process.

[0045] As a preferred embodiment of the above embodiment, the control module further includes: an interrupt controller, the input end of the interrupt controller is connected to the third output end of the central controller. The interrupt controller provides an additional layer of safety, that is, when the PID controller fails or fails to respond to the system status in time, the interrupt controller can independently detect the abnormal situation and stop the system operation to avoid further damage or danger. The interrupt controller can respond to various emergency situations, including not only abnormal temperature, pressure, and flow of the cooling system, but also power supply failure, sensor failure, etc. In this way, even if the system encounters unexpected problems, the interrupt controller can handle them in time. Combining the interrupt controller with the PID controller can improve the integrity and stability of the system. The PID controller is mainly responsible for normal temperature control, while the interrupt controller is used as a backup mechanism to ensure the safe operation of the system when abnormal situations occur.

[0046] like Figure 2 As shown, in the above embodiment, the central controller includes:

[0047] A comparator compares the received data with a preset threshold and outputs a feedback signal;

[0048] Fault diagnosis module, which determines the faults in the system based on the feedback signal;

[0049] The comparator input end is the input end of the central controller, the comparator output end is connected to the fault diagnosis module input end, and the first output end and the second output end of the fault diagnosis module are respectively the first output end and the second output end of the central controller.

[0050] The comparator is responsible for comparing the received data with the preset thresholds. These data can be real-time information from the sensor, such as temperature, pressure, etc. The comparator generates a corresponding output signal based on the comparison result to feedback whether the transmitted data reaches the preset threshold; after the fault diagnosis module receives the feedback signal from the comparator, it performs fault analysis and diagnosis based on these signals. Once a fault or abnormality is detected in the system, the fault diagnosis module can generate corresponding fault diagnosis information and output it to the PID controller. The PID controller regulates the system based on the received information.

[0051] In this embodiment, the sensor module includes at least one of a flow sensor, a pressure sensor and a temperature sensor. The flow sensor is used to monitor the flow velocity or flow change of the coolant in the cooling pipe in real time, and detect whether there is flow abnormality, such as pipe blockage leakage or sudden change of flow velocity; the pressure sensor is used to measure the pressure change in the cooling pipe to determine whether there is pressure abnormality or coolant leakage in the cooling pipe; the temperature sensor is used to monitor the temperature change of the coolant in the cooling pipe to adjust the temperature range of the cooling system to maintain normal operation; the sensor module provides key information for the monitoring of the cooling system, helps to ensure the safe and stable operation of the system, and improves the efficiency and reliability of the system.

[0052] In order to facilitate monitoring of the cooling system status, in this embodiment, Figure 3 As shown, the fault monitoring system also includes: a display module, the input end of the display module is connected to the third output end of the control module. The display module is used to display the operating status and fault information of the system to the operator or maintenance personnel. For example, the display module can be a liquid crystal display screen to provide operators with clear and intuitive display effects, helping them to better monitor and manage the operating status of the system and ensure the safe and stable operation of the system.

[0053] In this embodiment, the fault monitoring system further includes a mobile terminal, and the mobile terminal communicates wirelessly with the control module. By wirelessly connecting the mobile terminal with the control module, the user can achieve remote monitoring and management, and improve the response speed and flexibility of the system, wherein the mobile terminal is a tablet computer or a mobile phone. Whether it is a tablet computer or a smart phone, they provide users with a convenient and fast remote monitoring and management method, so that users can timely understand the system operation status and take necessary measures to ensure the safe and stable operation of the system.

[0054] As a preferred embodiment of the above, the alarm module includes at least one of a buzzer and a warning light. Generally, in the fault monitoring system of the cooling system, the buzzer and the warning light can be used at the same time to provide multiple alarm modes and increase the chance of people finding faults. When the system detects a problem with the cooling system, the buzzer and the warning light can be triggered at the same time to ensure that the operator or maintenance personnel can respond quickly and take timely actions to ensure the safe operation of the system.

[0055] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
