For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] As mentioned in the background technology, the hot runner system plays a vital role in modern injection molding production. The traditional hot runner system has a complex internal structure, especially the nozzle and runner parts, which makes cleaning extremely difficult. This not only increases maintenance costs, but may also cause production delays and product quality problems. It requires manual disassembly and cleaning of multiple components. The operation process is complicated and time-consuming, and requires high professional skills of the operators. Long-term downtime due to cleaning and maintenance will seriously affect production efficiency and corporate economic benefits. Through intelligent control, precise cleaning component movement control can be achieved, thereby comprehensively improving cleaning efficiency and reducing errors in human operation. The intelligent system can achieve more precise temperature control and time management, optimize the entire injection molding process, ensure product quality and speed up production.

[0045] In order to improve the above-mentioned problems, the present application proposes a hot runner intelligent control system and method.

The cleaning component can penetrate deep into the hot runner nozzle, ensuring more thorough cleaning, thereby improving the quality of the molten plastic and reducing production defects, and quick and effective cleaning. The process reduces downtime caused by maintenance, allowing the production line to continue to operate at a higher efficiency. Regular use of cleaning components for cleaning helps prevent failures in the flow system, thereby extending the service life of the equipment and reducing long-term maintenance costs. The use of rotating components enables precise cleaning position control, ensuring the accuracy and repeatability of the cleaning process, and providing the possibility for automated cleaning.

[0046] First embodiment

[0047] See also Figure 1-5 As shown, a hot runner intelligent control system according to an embodiment of the present application includes:

[0048] A base 1, wherein the base 1 is used to be fixed on the hot flow plate;

[0049] A rotating assembly 2, one end of which is fixedly connected to the top of the base 1;

[0050] A cleaning component 3, wherein a mounting end of the cleaning component 3 is fixedly connected to the other end of the rotating component 2, and the cleaning component 3 is used for cleaning the inside of the hot runner nozzle.

[0051] In some specific embodiments, the base 1 is provided with through holes which are fixedly connected to the heat flux plate by bolts.

[0052] In some specific embodiments, a suction cup is disposed at the bottom of the base 1 .

[0053] It should be understood that by providing a suction cup at the bottom of the base 1, the stability of the connection between the entire system and the heat flow plate can be greatly increased. The suction cup can provide a strong adsorption force to ensure that the base and the heat flow plate are closely connected, reducing the displacement problem caused by vibration or other external forces. In the injection molding production process, the operation of the machine is often accompanied by a certain vibration. The design of the suction cup can effectively prevent the loosening caused by mechanical vibration, thereby maintaining the stable operation of the system. The suction cup can adapt to and seal the heat flow plate with different surface states, whether it is a smooth or slightly rough surface, it can provide a good adsorption effect, enhancing the universal applicability of the system. During operation, if the connection part is not stable enough, it may cause the assembly to break due to operating errors or equipment failures. The use of suction cups can greatly reduce the risk of parts falling off. When operators perform system maintenance or cleaning work, stable suction cup connection can reduce pinching or scratching injuries that may be caused by adjusting or disassembling components. The suction cup not only provides strong adsorption force, but also allows relatively easy disassembly and reinstallation, which is especially important for regular system maintenance and cleaning, reducing the difficulty and time cost of maintenance. The design of setting suction cups at the bottom of base 1 plays a vital role in the hot runner intelligent control system, which not only improves the stability and safety of the system, but also facilitates daily maintenance and operation to a great extent. This design innovation reflects a deep understanding and response to the actual operation needs of injection molding production, and helps to promote the efficiency and stability of the production process.

[0054] In some specific embodiments, the rotating assembly 2 includes:

[0055] An electric telescopic column 4, wherein the bottom mounting end of the electric telescopic column 4 is fixedly connected to the top of the base 1, and the axis of the electric telescopic column 4 coincides with the axis of the base 1;

[0056] A first electric rotating shaft 5, wherein the first electric rotating shaft 5 is disposed at the top telescopic end of the electric telescopic column 4, and the first electric rotating shaft 5 is rotatably connected to the top telescopic end of the electric telescopic column 4;

[0057] A first connecting rod 6, wherein the first connecting rod 6 is arranged perpendicular to the electric telescopic column 4, and one end of the first connecting rod 6 is fixedly connected to the rotating end of the first electric rotating shaft 5;

[0058] a second electric rotating shaft 7, a rotating end of which is fixedly connected to the first connecting rod 6;

[0059] A second connecting rod 8 , one end of which is rotatably connected to the second electric rotating shaft 7 , and the other end of which is fixedly connected to the mounting end of the cleaning component 3 .

[0060] In some specific embodiments, the second connecting rod 8 coincides with the axis of the cleaning component 3 .

[0061] In some specific embodiments, the cleaning component 3 includes:

[0062] A mounting plate 9, wherein a liquid inlet 10 is disposed on the top of the mounting plate 9, wherein the transverse cross section of the mounting plate 9 is a circular structure, wherein a plurality of first liquid discharge ports 11 are disposed in a circular array on the side wall of the mounting plate 9 with the center of the mounting plate 9 as the axis, and a plurality of second liquid discharge ports 12 are disposed in a circular array on the bottom of the mounting plate 9 with the center of the mounting plate 9 as the axis;

[0063] The regulating component 13 is disposed in the second liquid discharge port 12 .

[0064] In some specific embodiments, the liquid inlet 10 extends into the interior of the mounting plate 9 and communicates with a plurality of the first liquid discharge ports 11 and a plurality of the second liquid discharge ports 12 .

[0065] In some specific embodiments, the adjustment component 13 includes:

[0066] a third electric rotating shaft 14, wherein the third electric rotating shaft 14 is disposed in the second liquid discharge port 12, and the third electric rotating shaft 14 is rotatably connected to the inner wall of the second liquid discharge port 12;

[0067] A connecting column 15, one end of which is fixedly connected to the third electric rotating shaft 14, and the outer diameter of the connecting column 15 is smaller than the inner diameter of the second liquid discharge port 12;

[0068] A spring 16, wherein the spring 16 is sleeved on the outside of the connecting column 15, and the bottom of the spring 16 is fixedly connected to the third electric rotating shaft 14;

[0069] The sleeve 17 is sleeved outside the connecting column 15 , the bottom of the sleeve 17 is fixedly connected to the top of the spring 16 , and the inner wall of the sleeve 17 is slidably connected to the outer wall of the connecting column 15 .

[0070] It should be understood that, through the cooperation of the third electric rotating shaft 14 and the connecting column 15, the effective diameter of the second liquid discharge port 12 can be accurately controlled, thereby finely adjusting the liquid flow rate passing therethrough. This design enables the system to adjust the flow rate according to different cleaning needs, ensuring the cleaning effect while avoiding waste of resources. For hot runner nozzles of different degrees of contamination and different types, the flow rate control achieved by the adjustment component 13 can provide a more appropriate cleaning force, thereby protecting the internal structure of the nozzle from damage and extending the service life of the equipment. The electronic control method of the third electric rotating shaft 14 can quickly respond to the instructions of the control panel and quickly adjust the size of the liquid discharge port. This rapid response saves valuable time for the entire cleaning process and improves production efficiency. The control panel provides a simple and intuitive operating interface, allowing operators to easily and accurately control the third electric rotating shaft 14 without complex settings or long-term training, reducing the difficulty of operation. Compared with manual adjustment, the use of the electric rotating shaft greatly simplifies the operating process. The operator only needs to complete all adjustments through the control panel, reducing manpower. The use of electric control systems reduces direct contact between operators and mechanical equipment, especially in high temperature and high pressure working environments, effectively improving operational safety. The modular design of the adjustment component 13 enables it to be quickly disassembled and installed when maintenance or replacement is required, without the need for complex tools, greatly reducing maintenance costs and time. Whether it is daily production changes or performance changes caused by long-term equipment aging, the adjustment component 13 can adapt to these changes through simple adjustments, ensuring long-term stable operation. The fine electric control capability ensures that the position of the connecting column 15 and the sleeve 17 can be adjusted very accurately, thereby accurately controlling the size of the drain port to meet high-precision industrial needs. The design of the adjustment component 13 plays a vital role in the hot runner intelligent control system, which not only improves system performance and simplifies the operating process, but also greatly facilitates daily maintenance and adjustment work. This design innovation reflects a deep understanding of the actual operational needs of injection molding production, helps to promote the efficiency and stability of the production process, and brings higher economic benefits and competitive advantages to enterprises.

[0071] In some specific embodiments, the outer diameter of the mounting plate 9 matches the inner diameter of the hot runner nozzle.

[0072] Second embodiment

[0073] In some specific embodiments, a hot runner intelligent control method includes the following steps:

[0074] 1) Clean the surface of the hot runner hot plate and install the base 1 on the hot plate;

[0075] 2) controlling the first electric rotating shaft 5, the second electric rotating shaft 7, and the electric telescopic column 4 through the control panel to allow the cleaning component 3 to enter the hot runner nozzle;

[0076] 3) Controlling the third electric rotating shaft 14 to drive the connecting column 15 to swing, and adjusting the diameter of the second liquid discharge port 12 to control the flow rate of the liquid in the second liquid discharge port 12 .

[0077] It should be understood that by cleaning the surface of the hot runner hot plate and quickly installing the base 1 on the hot plate, the entire preparation process is simple and fast, reducing equipment downtime, thereby improving overall production efficiency. The control panel is used to control the electric rotating shaft and the electric telescopic column to automatically enter the hot runner nozzle. This automated step not only saves manpower, but also shortens the cleaning time and improves work efficiency. It can quickly make adjustments according to different cleaning needs, such as adjusting the flow rate of the drain port by swinging the third electric rotating shaft. This flexibility greatly improves operating efficiency and cleaning effect. Through a sophisticated electric control system, the position and depth of the cleaning component entering the hot runner nozzle can be very accurately controlled to ensure that the cleaning process is thorough and accurate, avoiding errors that may be caused by manual operation. The diameter of the drain port is adjusted by controlling the swing of the connecting column, and then the amount of liquid flowing out is accurately controlled. This precise control makes cleaning more efficient and also avoids waste of liquid. The movement of the cleaning component and the liquid flow rate can be accurately controlled, and the settings can be optimized for different degrees of contamination and nozzle types to ensure that each cleaning can achieve the best effect.
