[0055] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation.

[0060] The mold body also includes a monitoring unit to monitor and adjust the temperature in real time during the hot vulcanization process to ensure uniform heat conduction in each process;

[0061] Its integrity and stability enable the mold 1 to maintain the accuracy of shape and size under high temperature and high pressure environments. The modular design of the movable block 2 allows for quick replacement to meet the production requirements of different cable diameters, greatly improving the flexibility and efficiency of production. At the same time, the real-time monitoring and adjustment functions of the monitoring unit ensure the temperature uniformity of the hot vulcanization process and avoid product quality problems caused by temperature fluctuations. This design makes the production process more intelligent and automated, thereby reducing labor costs and improving the efficiency and capacity of the production line.

[0062] The mold 1 is composed of a first mold and a second mold combined by a locking structure. A movable block installation cavity 3 for installing a movable block 2 is provided at one end of the mold 1, and a connector installation cavity 4 for installing a connector wrapped with rubber is provided at the other end. The movable block installation cavity 3 and the connector installation cavity 4 are connected.

[0063] By dividing the mold 1 into a first mold and a second mold and merging them with a locking structure, the sealing and stability of the mold 1 can be effectively improved. This design not only simplifies the operation and maintenance process of the mold 1, but also ensures that the shape of the inner cavity of the mold 1 remains unchanged, avoiding product defects caused by deformation of the mold 1. At the same time, the connection design of the movable block installation cavity 3 and the connector installation cavity 4 makes the installation and replacement of the movable block 2 easier, thereby improving production efficiency.

[0065] This flexibility enables manufacturers to quickly adjust production strategies in the face of changing market demands, thereby reducing costs and shortening delivery times. The inner cavity of the movable block 2 is designed to be funnel-shaped, and cable diameters of various sizes can be accommodated by simply changing the size of the inner cavity of the movable block 2. The inner shell of the movable block 2 can be changed to make vulcanization packages of different sizes and shapes, which not only improves the adaptability of the movable block 2, but also provides better sealing performance during the hot vulcanization process. This design ensures the uniform distribution of the vulcanized material by optimizing fluid dynamics, thereby improving the overall strength and durability of the product. In addition, the consistency of the outer dimensions of the movable block 2 standardizes the production process, facilitates mass production and quality control, and further reduces production errors caused by human factors.

[0066] The inner walls of the mold 1 and the movable block 2 are coated with a release agent to reduce adhesion after hot vulcanization;

[0067] The adhesion between the rubber and the mold 1 after hot vulcanization is effectively reduced, ensuring the multiple service life of the mold 1. This design not only improves the production efficiency of the product, shortens the demoulding time, but also reduces the loss of the mold 1 and saves maintenance costs. By reducing adhesion, the labor intensity of the operator during demoulding is also significantly reduced, further improving the safety and comfort of operation.

9. The method for manufacturing a modular hot vulcanization mold for a tail clip adapted to cable diameter matching according to claim 7, characterized in that: In S71, the monitoring unit comprises a temperature sensing module for real-time monitoring of the temperature in the mold (1), a data acquisition module for transmitting data collected by the temperature sensing module to the control module, a control module for processing the data and controlling the heating process of the vulcanizing furnace, an alarm module for issuing an alarm when the temperature exceeds a set range, and a display module for displaying temperature data and the status of the monitoring unit, and the control method comprises: S711. Before starting, the system self-checks all modules to ensure that they are working properly, then sets the target temperature and time, and inputs the hot vulcanization process parameters; S712, the temperature sensing module collects temperature data in the mold (1) once per second, and then the data acquisition module transmits the temperature data to the control module in real time; S713, the control module analyzes the received temperature data, compares the current temperature with the set target temperature, and determines whether heating needs to be adjusted; S714: If the current temperature is lower than the target temperature, the control module issues a heating instruction to increase the heat of the vulcanizing furnace; If the current temperature is higher than the target temperature, the control module issues a cooling command to reduce the heat of the vulcanization furnace; Continuously adjust to ensure that the temperature inside the mold (1) remains within a set range; S715. Once the temperature exceeds the set safety range, the control module immediately triggers the alarm module and automatically cuts off the heating source of the vulcanizing furnace to prevent equipment damage, and records the over-temperature event and duration for subsequent analysis; S716. The monitoring unit regularly records temperature data and heating status, stores them in the system database, provides data feedback to the operator, and displays the temperature change curve and system status through the display module for easy observation and analysis; S717: After the hot vulcanization is completed, the control module sends an end signal and turns off all heating equipment.
