[0002] Pipe extrusion dies have achieved modular, automated, and intelligent design, significantly improving the reliability, stability, and precision of the equipment. Modern electronic and computer control technologies are also widely used in the control systems of large-diameter plastic pipe extrusion equipment, enabling online detection and microcomputer closed-loop control of process parameters throughout the extrusion process, ensuring stable process conditions and product precision.

[0003] A pipe mold distribution device is a special distributor that is usually installed in a pipe mold system to distribute fluids (such as water, gas, oil, etc.) or signals (such as electrical signals, optical signals, etc.) to different pipes or molds according to a predetermined ratio or requirements. At present, most plastic pipe molds are integral structures, which are inconvenient to disassemble and clean after processing and cannot effectively release the pressure of fluid processing. When the mold fails, it cannot be quickly disassembled, which will affect the service life of the mold and also reduce the quality of the extruded products. Utility Model Content

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0035] One embodiment of this utility model, in conjunction with Figure 1As shown, the fluid distribution device provided by this utility model is used in conjunction with a pipe extrusion die. The extruded molten material is pre-mixed by the fluid distribution device before entering the die. The pipe extrusion die is mainly used to process mixed pipe fluid materials, dispersing fluid stress and ensuring thorough mixing. The distribution device can be connected to the inner and outer molds to form a mold for direct use, enabling material control and processing. It can also be applied to fluid distribution in other extrusion devices, including a distribution section 3, an inlet section 1, and a connecting section 2. The distribution section 3 and the inlet section 1 are connected via the connecting section 2. The connecting section 2 also serves to connect to the outer mold, fixing the fluid distribution device to the mold. The distribution section 3 can be connected to the inner mold. The distribution device is installed as a whole mold by connecting to the inner and outer molds. By designing the fluid distribution device as three detachable parts, it is easy to disassemble and clean during processing and production.

[0036] The inlet section 1 includes an inlet end and an outlet end, and an inner conveying channel 5 is formed between the inlet end and the outlet end of the inlet section 1. The inner conveying channel 5 passes through the inlet end 1 and the connecting part 2, and is used to convey fluid to the distribution section 3. The distribution section 3 includes a first end and a second end. The first end is connected to the connecting part 2 and is provided with a diversion channel 7. The inner conveying channel 5 is connected to the diversion channel 7. A spiral channel 6 is formed on the outer surface of the distribution section 3. The depth of the spiral channel 6 gradually decreases from the first end to the second end. The diversion channel 7 is connected to the spiral channel 6. After the fluid enters the distribution device from the inlet section 1, it flows through the inner conveying channel 5 to the diversion channel 7. The distribution section 3 has a threaded structure to form a spiral channel 6 for the fluid flowing out of the diversion channel 7, which enables the fluid to flow along the spiral channel 6 and reduces the internal stress of the fluid.

[0037] More preferably, the surface of the spiral flow channel 6 is formed with several equally spaced threads, and the diversion flow channel 7 is formed with several outlets on the surface of the distribution section 3. Each outlet is connected to a flow channel formed by the threads. The outer diameter of the distribution section 3 is reduced in the direction of the thread extension. The fluid flowing out of the diversion flow channel 7 can enter the spiral flow channel 6, making the fluid more uniform. The outer diameter of the distribution section 3 is reduced, so that the fluid flowing out of the diversion flow channel 7 can flow in a straight line along the direction of the distribution section 3. The spiral flow channel 6 at the first end of the distribution section 3 is the deepest. As the depth in the spiral direction becomes shallower, the fluid flowing in the spiral becomes less and less, and the material gradually becomes a straight flow and slowly merges, so that the wall thickness of the processed product is uniform and there are no weld lines that affect the product quality.

[0038] In this embodiment, the dispensing part 3 and the connecting part 2 engage, and the inlet part 1 and the connecting part 2 engage, which increases the cooperation of the dispensing device, reduces the weight of the dispensing device, and enhances the sealing performance of the entire device.

[0039] The second end of the distribution section 3 is provided with a weight-reducing hole, which is a blind hole. The blind hole can reduce the weight of the distribution device and reduce the production cost of the mold during production.

[0040] One embodiment of this utility model, in conjunction with Figure 2 and Figure 3 As shown, the inlet end of the inlet portion 1 of the fluid distribution device of this utility model is equipped with an inlet connector. When the distribution device is being processed and mates with a mold, the inlet connector is fixedly connected to the inlet portion 1 and the connecting portion 2 by screws. The entire distribution device can be connected to external mechanical equipment for continuous processing and production through the inlet connector. In this embodiment, the fluid can enter the inner conveying channel 5 through the inlet portion 1. The inner conveying channel 5 is connected to the branch channel 7. The fluid can flow out of the hole at the first end of the distribution portion 3 through the branch channel 7 and can flow directly along the direction of the thread extension from the hole. Through the distribution portion 3, the fluid can enter the mold for processing or shaping.

[0041] Specifically, the inner conveying channel 5 is located at the center of the mold axis, and the diversion channel 7 diffuses the melt from the inner conveying channel away from the axis, and further flows out through the outlet to the surface of the distribution section 3, where it is further guided by the threads on the surface of the distribution section 3. The number of outlets can be 3, 4, 5, 6, or even more, depending on the size of the mold and the distribution section 3. Generally, with the same distribution section diameter, more outlets and more threads connected to the outlets, with smaller thread pitch, result in more uniform melt flow. Too many outlets lead to overly dense threads, which is detrimental to melt flow and reduces production efficiency. Those skilled in the art, based on their understanding of the technology and principles of this invention, can adjust the number of outlets and thread density according to actual needs, considering factors such as melt viscosity, distribution section diameter, length, and the gap size of the extrusion channel. Each outlet is connected to a corresponding thread; uniform thread distribution ensures even distribution of internal stress in the melt and prevents uneven pressure from the melt on the distribution device, thus preventing mold damage, improving mold utilization, and reducing mold costs.

[0042] One embodiment of this utility model, in conjunction with Figure 3As shown, a simplified description of the installation and use of the dispensing device is provided in this embodiment. The pipe extrusion die including the dispensing device includes a dispensing device, an inner mold part 9, and an outer mold part 8. The inner mold part 9 is fixedly connected to the second end of the dispensing part 3 by screws, and the outer mold part 8 is fixedly connected to the connecting part 2 by screws. An extrusion flow channel is formed between the outer mold part 8 and the inner mold part 9, and a spiral flow channel 6 is formed between the outer mold part 8 and the dispensing part 3. The spiral flow channel 6 is connected to the extrusion flow channel.

[0043] The gap between the distribution section 3 and the outer mold section 8 gradually widens along the direction of the distribution section 3. At this time, the melt can flow simultaneously along the direction of the spiral flow channel 6 and the straight direction of the distribution section 3. The two flow directions increase the flow rate of the melt, which can improve the overall working efficiency of the mold in use.

[0044] More preferably, when the dispensing device is in operation, the surfaces of the dispensing section 3, the inlet section 1, and the connecting section 2 that come into contact with the fluid are respectively provided with an anti-corrosion layer to reduce the corrosion of the dispensing device and the mold by the processing fluid.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit this utility model. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this application.
