Abstract
Description
Technical Field

[0002] A hot runner system is a system that uses heating to keep the plastic in the runner and gate in a molten state. The manifold is an important component of this system; heating elements provide heat to the manifold, ensuring that the plastic flowing from the main nozzle to each outlet is in a molten state.
[0003] Most existing manifolds are one-piece designs. One-piece manifolds require high machining precision, leading to complex manufacturing processes, increased processing difficulty, and significantly higher production costs. Furthermore, machining errors can negatively impact the uniformity of melt flow, easily causing inconsistent quality in injection molded parts. In addition, one-piece manifolds have higher maintenance costs. If blockages or damage occur inside the flow channels, repair or replacement often requires disassembling the entire manifold, increasing maintenance difficulty and costs.
[0004] Therefore, there is an urgent need for a manifold connection structure and a hot runner system to solve the above problems. Utility Model Content

[0043] This embodiment provides a diverter plate connection structure, which is disposed on the mounting plate 10, such as... Figures 1-3As shown, the flow divider connection structure includes a first flow divider 100, a second flow divider 200, and a connecting block 300. The first flow divider 100 has a first flow channel 110, and one end of the first flow channel 110 has a first mounting groove 120. The second flow divider 200 is spaced apart from the first flow divider 100 and has a second flow channel 210. One end of the second flow channel 210 near the first flow divider 100 has a second mounting groove 220. One end of the connecting block 300 is embedded in the first mounting groove 120, and the other end is embedded in the second mounting groove 220. The connecting block 300 has a connecting flow channel 310, and both ends of the connecting flow channel 310 are connected to the first flow channel 110 and the second flow channel 210 respectively to form a continuous melt flow channel. The fastening assembly 400 is used to fix the first flow divider 100 and the second flow divider 200 to the mounting plate 10. The first manifold 100 and the first flow channel 110 divide the melt in the main flow channel of the injection molding machine according to the cavity layout, guide the melt to flow evenly to the hot nozzle, participate in heat transfer and balance, and ensure that the melt state meets the injection molding requirements; the second manifold 200 and the second flow channel 210 rationally distribute the upstream melt and guide it to the subsequent components, playing a key guiding role in product molding.
[0044] The manifold connection structure provided in this embodiment forms a continuous melt flow channel through the splicing design of the first manifold 100, the connecting block 300, and the second manifold 200. This simplifies the manufacturing process of the melt flow channel, reduces processing difficulty, and lowers manufacturing costs. The design of the connecting block 300 can also balance the expansion deformation of the first manifold 100 and the second manifold 200 caused by high temperature, improving the stability of the manifold connection structure and the injection molding quality. Furthermore, the fastening component 400 fixes the first manifold 100 and the second manifold 200 to the mounting plate 10, which greatly shortens the maintenance time of the hot runner system, reduces maintenance costs, and improves the production efficiency of the hot runner system.
[0045] Optionally, such as Figure 2 and Figure 3 As shown, the fastening assembly 400 includes a first pad 410 and a first fastener 420. The first pad 410 is sandwiched between the mounting plate 10 and the first diverter plate 100. The first pad 410 has a first through hole 411. The first fastener 420 passes through the first diverter plate 100 and the first through hole 411 and is threadedly connected to the mounting plate 10, making the installation and fixing process of the first diverter plate 100 simpler, as fastening can be completed by threaded connection only. When the first diverter plate 100 needs to be maintained or replaced, it can be quickly disassembled by simply loosening the first fastener 420, which greatly shortens the maintenance time and reduces the maintenance cost.
[0046] It should be noted that, according to actual needs, the distance between the first diverter plate 100 and the mounting plate 10 can be adjusted by replacing the first pad 410 of different heights, thereby buffering and dispersing the pressure of the first fastener 420, ensuring that the first diverter plate 100 is firmly installed and subjected to uniform force, and ensuring the stability of the splicing structure.
[0047] Optionally, such as Figure 2 and Figure 3 As shown, the first fastener 420 is a first screw, and the first diverter plate 100 is provided with a first countersunk hole 130. The first screw passes through the first countersunk hole 130 and the first through hole 411 in sequence and is threadedly connected to the mounting plate 10. The first countersunk hole 130 allows the top of the first screw to be flush with or slightly lower than the upper surface of the first diverter plate 100, reducing the installation height and space occupation.
[0048] Optionally, such as Figure 3 As shown, the second diverter plate 200 includes a first plate 201 and a second plate 202. The first plate 201 and the second plate 202 are constructed in a T-shape, giving the second diverter plate 200 excellent bending and torsional resistance, significantly improving the overall rigidity and structural strength of the second diverter plate 200. In this embodiment, the mounting plate 10 is provided with a clearance hole 12, through which the second plate 202 can extend into the glue injection position.
[0049] Optionally, the fastening assembly 400 further includes a second pad 430, which is sandwiched between the mounting plate 10 and the first plate 201. The second pad 430 is at the same height as the first pad 410, and has a second through hole 431. A second fastener 440 passes through the first plate 201 and the second through hole 431 and is threadedly connected to the mounting plate 10, making the installation and fixing of the second diverter plate 200 simpler, requiring only a threaded connection for fastening. When maintenance or replacement of the second diverter plate 200 is required, quick disassembly can be achieved simply by loosening the second fastener 440, significantly shortening maintenance time and reducing maintenance costs. The distance between the first plate 201 and the mounting plate 10 can be adjusted by replacing the second pads 430 with different heights, buffering and dispersing the pressure of the second fastener 440 to ensure that the second diverter plate 200 is firmly installed, evenly stressed, and that the splicing structure is stable.
[0050] In this embodiment, the second pad 430 and the first pad 410 are at the same height, so that the first flow divider 100 and the second flow divider 200 are at the same height on the mounting plate 10, ensuring the smoothness of melt flow and improving injection molding quality.
[0051] Optionally, the second fastener 440 is a second screw. The first plate 201 has a second countersunk hole 2011 corresponding to the installation position of the second screw. The second screw passes through the second countersunk hole 2011 and the second through hole 431 in sequence and is threadedly connected to the mounting plate 10. The second countersunk hole 2011 allows the top of the second screw to be flush with or slightly lower than the upper surface of the second diverter plate 200, reducing installation height and space occupation, and improving space utilization. In this embodiment, two second screws are respectively provided on the left and right sides of the first plate 201 to ensure a more stable connection between the second diverter plate 200 and the mounting plate 10.
[0052] Optionally, the flow divider connection structure also includes a first positioning pin 500. The mounting plate 10 is provided with a first positioning groove 11, and the first plate body 201 is provided with a first positioning hole 2012. One end of the first positioning pin 500 is inserted into the first positioning groove 11, and the other end is inserted into the first positioning hole 2012. This can ensure that the second flow divider 200 is installed in an accurate position. In addition, the first positioning pin 500 can play a restraining role, reducing the misalignment of the second flow divider 200 caused by thermal deformation and ensuring the stability of the melt flow channel.
[0053] Optionally, the first mounting groove 120 and the second mounting groove 220 are respectively provided with sealing media. The sealing media are used to seal the connection between the connecting block 300 and the first diverter plate 100, and the connection between the connecting block 300 and the second diverter plate 200, to prevent leakage of the high-temperature melt during flow and improve the sealing performance and stability of the melt flow channel. The sealing media can be high-temperature resistant and corrosion-resistant high-performance sealing materials, such as silicone rubber, fluororubber, or polytetrafluoroethylene. These materials can maintain good elasticity and sealing performance in high-temperature environments, effectively preventing leakage of the melt at the connection between the first diverter plate 100 and the connecting block 300, and at the connection between the second diverter plate 200 and the connecting block 300.
[0054] Optionally, such as Figure 3 As shown, the manifold connection structure also includes a second positioning pin 600 and a third pad 700. The third pad 700 is sandwiched between the mounting plate 10 and the first manifold 100. One end of the second positioning pin 600 is inserted into the mounting plate 10, and the other end of the second positioning pin 600 passes through the third pad 700 and is inserted into the first manifold 100. The axis of the second positioning pin 600 is aligned with the center line of the first manifold 100 along its length, ensuring the accurate installation position of the first manifold 100, maintaining the alignment accuracy of the first manifold 100, preventing melt flow channel misalignment, thereby improving the uniformity of melt flow and enhancing the consistency and quality of injection molded products. Furthermore, the third pad 700 provides additional support for the first manifold 100, further improving the stability of the first manifold 100.
[0055] The hot runner system provided in this embodiment includes multiple manifold connection structures as described above, which can improve injection molding quality, reduce maintenance costs, and increase production efficiency.
