Abstract
Description
Technical Field
[0001] This invention relates to the technical field of hot runners, and more specifically, to a manifold structure, a method for installing the manifold structure, and a hot runner. Background Technology
[0002] Hot runner systems are a crucial component widely used in injection molds. Their function is to transport molten plastic from the injection machine nozzle to the mold cavity and maintain the molten plastic within the runner throughout the injection cycle. A typical hot runner system includes components such as a manifold, hot nozzle bodies, support blocks, and heaters. The manifold distributes the molten plastic to each hot nozzle, which then directly injects the plastic into the mold cavity. Runner plugs seal off non-working runner ports.
[0003] In existing technologies, manifolds, hot nozzles, and flow channel plugs are often designed as a single unit. While this single-unit structure simplifies the assembly process to some extent, it presents the following problems: when a component in the hot runner system (such as a hot nozzle or the internal flow channel of the manifold) becomes blocked or damaged, the entire manifold, hot nozzle, and flow channel plug must be disassembled for repair or replacement. This is extremely inconvenient, results in high maintenance costs and long cycles, and seriously affects production efficiency.
[0004] Furthermore, hot runner systems require heating to high temperatures (typically 200°C to 400°C) during operation, causing significant thermal expansion of the manifold. Since the manifold and hot nozzle are usually connected by threads (e.g., the hot nozzle threads mate with threaded holes on the manifold), and the direction and magnitude of the manifold's thermal expansion are difficult to control precisely, the resulting thermal expansion force directly acts on the hot nozzle threads. After prolonged or repeated thermal cycles, these threads are prone to damage, jamming, deformation, or even breakage due to excessive compressive stress. This leads to seal failure between the hot nozzle and the manifold, causing molten plastic to leak from the threaded connection (i.e., system leakage), severely affecting the quality of injection molded products, contaminating the mold, and even causing equipment malfunctions. Summary of the Invention
[0005] The purpose of this invention is to provide a manifold structure, a method for installing the manifold structure, and a hot runner, so as to solve the technical problems of thread damage and glue leakage caused by thermal expansion of the manifold in the prior art.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a flow divider structure, comprising: The first flow divider plate is on which the main nozzle is mounted. The second flow divider plate, both the first flow divider plate and the second flow divider plate are horizontally arranged, and there is a first gap between the first flow divider plate and the second flow divider plate, and the hot nozzle is installed on the second flow divider plate; The splitter insert connects the first splitter and the second splitter. An elastic limiting component is disposed within the second splitter plate and located at the end of the splitter plate insert, and the elastic limiting component abuts against the splitter plate insert; The first manifold, which expands due to heat, moves closer to the second manifold so that the first manifold and the second manifold come into contact.
[0007] According to the above-described diverter structure, the first diverter has a first inlay position, the second diverter has a second inlay position, and the diverter insert is disposed in the first inlay position and the second inlay position to connect the first diverter and the second diverter with the first gap.
[0008] According to the above-described flow divider structure, the first flow divider has a horizontal first flow channel, the second flow divider has a vertical second flow channel, and the flow divider insert has a corner flow channel. The two ends of the corner flow channel are respectively connected to and communicate with the first flow channel and the second flow channel.
[0009] According to the diverter structure described above, the elastic limiting component includes: The plug screw includes an integrally formed first plug nut and a screw rod. The second diverter plate is also provided with a plug mounting cavity. The plug screw is located in the plug mounting cavity, and the first plug nut is threadedly connected to the inner wall of the plug mounting cavity. An elastic component is sleeved on the outside of the screw. One end of the elastic component is limited by the diverter insert, and the other end of the elastic component is limited by the first plug nut.
[0010] According to the above-described diverter structure, the diverter insert has a groove at one end near the elastic component, and a first support step is formed around the groove. The first support step is used to support the elastic component. The screw is aligned with the groove, the depth of the groove is the second gap between the distributor insert and the screw, and the second gap and the first gap are equal.
[0011] According to the above-described diverter plate structure, the elastic component includes a spring, which is sleeved on the outside of the screw. One end of the spring is limited by the diverter plate insert, and the other end of the spring is limited by the first plug nut.
[0012] According to the above-described diverter structure, the inner diameter of the plug mounting cavity is larger than the inner diameter of the second insert position, forming a second support step. The second support step is used to limit the position of the first plug nut.
[0013] According to the above-described diverter structure, a second plug nut is also installed in the plug mounting cavity. The second plug nut is threadedly connected to the plug mounting cavity, and the second plug nut and the first plug nut are stacked on top of each other.
[0014] Secondly, the present invention also provides an installation method for a splitter structure, applied to the splitter structure described above, comprising: Calculate the value of the first gap caused by thermal expansion of the distance between the main nozzle and the hot nozzle; The first splitter plate, the second splitter plate, the splitter plate insert, and the elastic limiting assembly are designed according to the value of the first gap. Assemble the manifold structure.
[0015] Thirdly, the present invention also provides a hot runner, including the above-described manifold structure, wherein the hot runner further includes a main nozzle, and the main nozzle is connected to the first manifold. The hot runner also includes a hot nozzle, which has hot nozzle threads that are threadedly connected to the threaded hole of the second flow divider plate.
[0016] The beneficial effects of the manifold structure, the manifold structure installation method, and the hot runner provided by this invention are at least as follows: (1) The manifold structure of the present invention consists of a split first manifold, a second manifold, a manifold insert, and an elastic limiting component, which can be quickly disassembled. When the flow channel is blocked or needs maintenance, the manifold can be separated separately without disassembling the entire hot runner, which greatly simplifies maintenance operations, shortens downtime, and reduces maintenance costs. Furthermore, through the modular manifold design, each functional module can be replaced or adjusted independently as needed, avoiding the disadvantage of "all are damaged if one is damaged" in the traditional integrated structure, and enhancing the modularity and scalability of the system.
[0017] (2) The hot nozzle is installed on the second manifold plate, and the main hot nozzle is installed on the first manifold plate. When the manifold plate expands due to heat, the first manifold plate begins to expand towards the second manifold plate with the main nozzle as the positioning standard. The first manifold plate gradually engages with the second manifold plate until they are fully engaged. The second manifold plate does not shift or deform, and the thermal expansion force is effectively isolated or absorbed. As a result, the hot nozzle installed on the second manifold plate does not tilt or shift. The hot nozzle threads and other accessories are always in a normal stress and working state, which effectively avoids damage, jamming or deformation of the hot nozzle threads due to excessive stress. This significantly improves the structural stability and reliability of the entire hot runner, reduces various failures caused by thermal stress, extends the overall service life of the system, and improves the quality consistency of injection molded products. At the same time, it completely solves the problems of thread jamming, loosening or sealing failure caused by abnormal stress at the threaded connection due to the thermal expansion of the manifold plate in traditional threaded hot runners. It eliminates the risk of molten plastic leaking from the threaded connection and ensures the cleanliness and safety of the production process. Attached Figure Description

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Please see Figure 1 and Figure 2 This embodiment provides a flow divider structure 100, including a first flow divider 10, a second flow divider 20, a flow divider insert 30, and an elastic limiting component 40. The main nozzle 200 is mounted on the first flow divider 10; both the first flow divider 10 and the second flow divider 20 are horizontally arranged, and a first gap L2 exists between them (see...). Figure 5A hot nozzle 300 is mounted on the second splitter plate 20; the first splitter plate 10 and the second splitter plate 20 are connected by the splitter plate insert 30; the elastic limiting component 40 is disposed within the second splitter plate 20 and located at the end of the splitter plate insert 30, and the elastic limiting component 40 abuts against the splitter plate insert 30; the first splitter plate 10, which expands due to heat, moves closer to the second splitter plate 20 so that the first splitter plate 10 and the second splitter plate 20 fit together (see also...). Figure 3 and Figure 4 Optionally, the expansion value of the distance L1 between the main nozzle 200 and the hot nozzle 300 is close to 0.9976, and L2 = L1 * 0.9976.
[0024] The working principle of the diversion plate structure 100 provided in this embodiment is as follows: The diverter structure 100 provided in this embodiment sets the diverter as a split first diverter 10 and a second diverter 20, and connects the first diverter 10 and the second diverter 20 through a diverter insert 30. The diverter insert 30 ensures the diverter function of the diverter. Before the first diverter 10 thermally expands, there is a first gap L2 between the first diverter 10 and the second diverter 20. When the diverter expands due to heat, the first diverter 10 will start to thermally expand towards the second diverter 20 with the main nozzle 200 as the positioning standard. The first gap L2 begins to engage with the second diverter 20 based on the thermal expansion of the first diverter 10. Finally, the first gap L2 becomes zero, and the diverter insert 30 moves accordingly. The elastic limiting component 40 is squeezed by the thermal expansion force and limits the position of the diverter insert 30.
[0025] The beneficial effects of the diversion plate structure 100 provided in this embodiment are as follows: (1) The manifold structure 100 provided in this embodiment is composed of a split first manifold 10, a second manifold 20, a manifold insert 30, and an elastic limiting component 40. It can be quickly disassembled. When the flow channel is blocked or needs maintenance, the manifold can be separated separately without disassembling the entire hot runner 1000, which greatly simplifies maintenance operations, shortens downtime, and reduces maintenance costs. Furthermore, through the modular manifold design, each functional module can be replaced or adjusted independently as needed, avoiding the disadvantage of "all are damaged if one is damaged" in the traditional integrated structure, and enhancing the modularity and scalability of the system.
[0026] (2) The hot nozzle 300 is installed on the second manifold 20 and the main hot nozzle 300 is installed on the first manifold 10. When the manifold is heated and expanded, the first manifold 10 begins to expand towards the second manifold 20 with the main nozzle 200 as the positioning standard. The first manifold 10 gradually engages with the second manifold 20 until they are fully engaged. The second manifold 20 does not shift or deform. The thermal expansion force is effectively isolated or absorbed, so that the hot nozzle 300 installed on the second manifold 20 does not tilt or shift. The hot nozzle thread 301 and other accessories are always in a normal stress and working state, thereby effectively avoiding damage, jamming or deformation of the hot nozzle thread 301 due to excessive stress. This significantly improves the structural stability and reliability of the entire hot runner 1000, reduces various failures caused by thermal stress, extends the overall service life of the system, and improves the quality consistency of injection molded products. At the same time, it completely solves the problems of thread jamming, loosening or sealing failure caused by abnormal stress at the threaded connection due to thermal expansion of the manifold in the traditional threaded hot runner 1000, eliminates the risk of molten plastic leaking from the threaded connection, and ensures the cleanliness and safety of the production process.
[0027] In one embodiment, see Figure 3 The first diverter plate 10 has a first insert position 11, and the second diverter plate 20 has a second insert position 21. The diverter plate insert 30 is disposed in the first insert position 11 and the second insert position 21 to connect the first diverter plate 10 and the second diverter plate 20, which have the first gap L2. The arrangement of the first insert position 11 and the second insert position 21 enables the first diverter plate 10 and the second diverter plate 20 to be stably connected, and the connection method is simple.
[0028] In one embodiment, see Figure 2 and Figure 3 The first diverter plate 10 has a horizontal first flow channel 12, the second diverter plate 20 has a vertical second flow channel 22, and the diverter plate insert 30 has a corner flow channel 31. The two ends of the corner flow channel 31 are respectively connected to and communicate with the first flow channel 12 and the second flow channel 22.
[0029] The first flow channel 12 in the first manifold 10 and the second flow channel 22 in the second manifold 20 are respectively connected to both ends of the corner flow channel 31 in the manifold insert 30, ensuring that the molten plastic injected from the main nozzle 200 can flow smoothly into the hot nozzle 300. It should be understood that before being subjected to thermal expansion force, the corner flow channel 31 and the second flow channel 22 are offset but remain connected, and the width of the offset is the width of the first gap L2.
[0030] In one embodiment, see Figure 3The elastic limiting component 40 includes a plug screw 41 and an elastic component 42. The plug screw 41 includes an integrally formed first plug nut 411 and a screw 412. The second diverter plate 20 is also provided with a plug mounting cavity 23. The plug screw 41 is disposed in the plug mounting cavity 23, and the first plug nut 411 is threadedly connected to the inner wall of the plug mounting cavity 23. The elastic component 42 is sleeved on the outside of the screw 412. One end of the elastic component 42 is limited by the diverter plate insert 30, and the other end of the elastic component 42 is limited by the first plug nut 411.
[0031] When the first distributor plate 10 expands due to heat and shifts towards the second distributor plate 20 (hot state), the first distributor plate 10 pushes the distributor plate insert 30 to move. The distributor plate insert 30 pushes the elastic component 42, causing the elastic component 42 to be compressed. The distributor plate insert 30 approaches the plug screw 41 until it abuts against the screw 412, thus limiting the displacement position of the distributor plate insert 30. When the first distributor plate 10 does not deform due to thermal expansion (cold state), the elastic component 42 recovers its elastic deformation, and the distributor plate insert 30 returns to its original position under the action of the elastic component 42, and the first distributor plate 10 returns to its original position. The elastic limiting component 40 described above has a simple structure and stable operation.
[0032] In one embodiment, see Figure 2 and Figure 5 The diverter insert 30 has a groove 24 at one end near the elastic component 42. Correspondingly, a first support step 25 is formed around the groove 24. The first support step 25 is used to support the elastic component 42. The screw 412 is aligned with the groove 24. The depth of the groove 24 is the second gap L3 between the diverter insert 30 and the screw 412, and the second gap L3 and the first gap L2 are equal.
[0033] When the first diverter plate 10 moves due to thermal expansion, the distance it can move (first gap L2) is exactly equal to the depth of the groove 24 (i.e., second gap L3). This causes the first diverter plate 10 and the diverter plate insert 30 to move, and the screw 412 is placed at the bottom of the groove 24. The first diverter plate 10 and the diverter plate insert 30 are stably limited, and the structure is stable.
[0034] In one embodiment, see Figure 4 The elastic component 42 includes a spring, which is sleeved on the outside of the screw 412. One end of the spring is limited by the diverter plate insert 30, and the other end of the spring is limited by the first plug nut 411.
[0035] In one embodiment, see Figure 4 The inner diameter of the plug mounting cavity 23 is larger than the inner diameter of the second insert position 21, forming a second support step 231. The second support step 231 is used to limit the first plug nut 411. The setting of the second support step 231 is used to limit the first plug nut 411, so that the second gap L3 is equal to the first gap L2.
[0036] In one embodiment, see Figure 3 and Figure 4 A second plug nut 43 is also installed in the plug mounting cavity 23. The second plug nut 43 is threadedly connected to the plug mounting cavity 23, and the second plug nut 43 is stacked on top of the first plug nut 411. The arrangement of the second plug nut 43 in conjunction with the arrangement of the first plug nut 411 can better prevent glue leakage.
[0037] Please see Figure 6 and Figure 7 This embodiment also provides an installation method for a splitter structure, which is applied to the splitter structure 100 described above, including: Step S100: Calculate the value of the first gap L2 caused by the thermal expansion of the distance L1 between the main nozzle 200 and the hot nozzle 300. Optionally, if the expansion value of the distance L1 between the main nozzle 200 and the hot nozzle 300 is close to 0.9976, then L2 = L1 * 0.9976.
[0038] Step S200: Design the first diverter plate 10, the second diverter plate 20, the diverter plate insert 30, and the elastic limiting component 40 according to the value of the first gap L2.
[0039] A first insert position 11 is provided in the first diverter plate 10, a second insert position 21 is provided in the second diverter plate 20, a corner flow channel 31 is provided in the diverter plate insert 30, and a groove 24 is provided at the end of the diverter plate insert 30. The groove 24 is denoted as the second gap L3, and the first gap L2 is equal to the second gap L3.
[0040] Step S300: Assemble the manifold structure and install the components of the hot runner 1000 in sequence. The installation sequence is as follows: Step S310: Install one end of the splitter plate insert 30 into the first insert position 11 of the first splitter plate 10; Step S320: Install the other end of the splitter plate insert 30 into the second insert position 21 of the second splitter plate 20; Step S330: The elastic limiting component 40 is installed from the side end of the second diverter plate 20 into the plug mounting cavity 23 of the second diverter plate 20, and the elastic limiting component 40 abuts against the diverter plate insert 30.
[0041] This embodiment also provides a hot runner 1000, including the aforementioned manifold structure 100. The hot runner 1000 further includes a main nozzle 200, which is connected to the first manifold 10. The hot runner 1000 also includes a hot nozzle 300, which has hot nozzle threads 301, and the hot nozzle threads 301 are threadedly connected to the threaded holes of the second manifold 20. Since the structure of the manifold structure 100 has been described in detail above, it will not be repeated here.
[0042] This embodiment provides a manifold structure 100, including a first manifold 10, a second manifold 20, a manifold insert 30, and an elastic limiting component 40. A main nozzle 200 is mounted on the first manifold 10; both the first manifold 10 and the second manifold 20 are horizontally arranged, and a first gap L2 exists between them. A hot nozzle 300 is mounted on the second manifold 20; the first manifold 10 and the second manifold 20 are connected via the manifold insert 30; the elastic limiting component 40 is disposed within the second manifold 20 and located at the end of the manifold insert 30, and the elastic limiting component 40 abuts against the manifold insert 30; the first manifold 10, upon thermal expansion, moves closer to the second manifold 20, causing the first manifold 10 and the second manifold 20 to fit together. This embodiment also provides an installation method for a manifold structure, applied to the aforementioned manifold structure, including: Step S100: Calculating the value of the first gap L2 caused by thermal expansion of the distance L1 from the main nozzle to the hot nozzle; Step S200: Designing a first manifold, a second manifold, a manifold insert, and an elastic limiting component based on the value of the first gap L2; Step S300: Assembling the manifold structure. This embodiment also provides a hot runner 1000, including the aforementioned manifold structure 100. The hot runner 1000 further includes a main nozzle 200, which is connected to the first manifold 10; the hot runner 1000 also includes a hot nozzle 300, which has hot nozzle threads 301, and the hot nozzle threads 301 are threadedly connected to the threaded hole of the second manifold 20.

It can be quickly disassembled. When the flow channel is blocked or needs maintenance, the manifold can be separated separately without disassembling the hot runner 1000 as a whole, which greatly simplifies the maintenance operation, shortens the downtime, and reduces the maintenance cost.

When the manifold is heated and expanded, the first manifold 10 begins to expand towards the second manifold 20 with the main nozzle 200 as the positioning standard.

The thermal expansion force is effectively isolated or absorbed, so that the hot nozzle 300 installed on the second manifold 20 does not tilt or shift. The hot nozzle thread 301 and other accessories are always in a normal stress and working state, thereby effectively avoiding damage, jamming or deformation of the hot nozzle thread 301 due to excessive stress. This significantly improves the structural stability and reliability of the entire hot runner 1000, reduces various failures caused by thermal stress, extends the overall service life of the system, and improves the quality consistency of injection molded products. At the same time, it completely solves the problems of thread jamming, loosening or sealing failure caused by abnormal stress at the threaded connection due to thermal expansion of the manifold in the traditional threaded hot runner 1000, eliminates the risk of molten plastic leaking from the threaded connection, and ensures the cleanliness and safety of the production process.
