[0002] A hot runner is a heating component system used in an injection mold to inject molten plastic particles into the cavity of the mold. A hot runner mold is a brand-new structure that heats the sprue and runner of a traditional mold or a three-plate mold, so that the sprue and runner do not need to be removed during forming.
[0003] The manifold plate is a very important component in the hot runner system. The manifold plate distributes the plastic melt transmitted by the main runner nozzle to each injection point nozzle through the runner.
[0004] Since the runner of the manifold plate is used to transport the molten plastic, there is a situation where the molten plastic solidifies in the runner, resulting in the molten plastic solidified in the runner being unable to be taken out, causing the runner to be blocked.
[0005] For example, the Chinese utility model patent with the publication number CN206520180U discloses a hot runner manifold plate. The upper manifold plate has an upper runner; an upper positioning block is arranged on the lower surface of the upper manifold plate and directly below the first end of the upper runner; the lower manifold plate has a lower runner; a lower positioning block is arranged on the lower surface of the lower manifold plate and directly below the first end of the lower runner; a runner connecting insert is arranged between the lower surface of the upper manifold plate and the upper surface of the lower manifold plate. The runner connecting insert is used to connect the second end of the upper runner and the first end of the lower runner and to make the included angle between the upper manifold plate and the lower manifold plate adjustable. According to a hot runner manifold plate of the utility model, the upper manifold plate and the lower manifold plate are butted through the runner connecting insert, and the adjustment of different distances between the second end of the lower runner and the first end of the upper runner can be realized, and it can be reused.
[0006] In the technical solution provided by the above patent, there is a situation where the runner is easily blocked by the molten plastic, and the existing structure of the manifold plate makes it inconvenient to take out the solidified molten plastic, bringing trouble to the actual use process.

[0009] The shunt plate body includes a bottom plate and a top plate. Among them, a groove for accommodating the top plate is formed on the upper surface of the bottom plate, and the top plate is detachably installed inside the groove.
[0010] The top plate extends along the direction of the horizontal passage, and the length of the top plate is greater than the length of the horizontal passage.

[0031] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0033] A hot runner manifold includes a manifold body 1 and a feed nozzle 4. A runner 2 is formed inside the manifold body 1, and the feed nozzle 4 is communicated with the runner 2. During actual use, the molten material enters the inside of the runner 2 through the feed nozzle 4, and then is transported by the runner 2 to each nozzle for spraying, thereby realizing the injection molding of the molten material. All of the above are prior arts.
[0034] The difference between the present utility model and the prior art is that as Figures 1-4As shown, the flow channel 2 includes a horizontal channel 21 and a vertical channel 22, and the horizontal channel 21 and the vertical channel 22 are perpendicular to each other. Specifically, the flow direction of the material in the vertical channel 22 is parallel to the flow direction of the material in the feed nozzle 4, and the flow direction of the material in the horizontal channel 21 is perpendicular to the flow direction of the material in the vertical channel 22. In this embodiment, as Figure 1 shown, the horizontal channel 21 is horizontally arranged, while the vertical channel 22 is vertically arranged.
[0035] Furthermore, as Figure 1 and Figure 3 shown, the diverter plate body 1 includes a bottom plate 11 and a top plate 12. Among them, a groove for accommodating the top plate 12 is formed on the upper surface of the bottom plate 11, and the top plate 12 is detachably installed inside the groove; the top plate 12 extends along the direction of the horizontal channel 21, and the length of the top plate 12 is greater than the length of the horizontal channel 21; the flow channel 2 includes a horizontal bottom channel 211 and a horizontal top channel 212. The horizontal bottom channel 211 is formed on the inner bottom surface of the groove, and the horizontal top channel 212 is formed on the lower surface of the top plate 12. The cross-sectional shapes of the horizontal bottom channel 211 and the horizontal top channel 212 are both semi-circular.
[0036] In the technical solution provided in this embodiment, when the flow channel 2 is blocked by the solidification of the molten material flowing through it, the staff can remove the top plate 12 to expose the solidified molten material in the top plate 12 inside the groove. At the same time, since the length of the top plate 12 is greater than the length of the horizontal channel 21, the molten material blocked inside the horizontal channel 21 can be completely exposed inside the groove, so that the solidified molten material can be taken out from the inside of the flow channel 2 through relevant tools, solving the problem of blockage of the flow channel 2.
[0037] As Figures 1-4 shown, the top plate 12 is detachably installed inside the groove through a pressing member 3. The pressing member 3 includes a pressing frame 31, and the frame edge of the pressing frame 31 is pressed against the joint of the bottom plate 11 and the top plate 12. The pressing frame 31 in this embodiment can be made of the same material as the top plate 12, and the pressing frame 31 and the top plate can be connected by a fixed connection (such as integrally formed) or a separated manner (such as the pressing frame 31 and the top plate 12 are each a separate part), which is not specifically limited here.
[0038] In the above solution, by providing the pressing frame 31 and pressing the frame edge of the pressing frame 31 against the joint of the bottom plate 11 and the top plate 12, on the one hand, the horizontal channel 21 and the vertical channel 22 can be fixedly connected together by using the pressing frame 31, and on the other hand, the joint of the bottom plate 11 and the top plate 12 can be shielded by the pressing frame 31 to prevent dirt from entering the inside of the groove.
[0039] Furthermore, as Figure 1 and Figure 4As described above, the pressing frame 31 is rectangular, and reinforcing ribs 32 are integrally formed inside the pressing frame 31. The reinforcing ribs 32 are used to improve the structural strength of the pressing frame 31, so that the pressing frame 31 can press the top plate 12 more tightly inside the groove.
[0040] In this embodiment, the pressing frame 31 is fixedly installed on the upper surface of the bottom plate 11 through a plurality of bolts 33.
[0041] Furthermore, the bolts 33 located on the long sides of the pressing frame 31 correspond to the positions of the reinforcing ribs 32. That is to say, the pressing frame 31 is rectangular, having a pair of long sides and a pair of short sides. As Figure 4 shown, bolts 33 are also provided on the long sides of the pressing frame 31, and the bolts 33 correspond to the end positions of the reinforcing ribs 32, so that the acting force generated by the bolts 33 can act on the reinforcing ribs 32.
[0042] As Figures 1-4 shown, the outer side surface of the top plate 12 and the inner wall surface of the groove are both stepped surfaces 13, and the two stepped surfaces 13 are arranged to match each other. The arrangement of the stepped surfaces 13 can improve the connection sealing performance between the outer side surface of the top plate 12 and the inner wall surface of the groove, and prevent leakage between the outer side surface of the top plate 12 and the inner wall surface of the groove.
[0043] In this embodiment, as Figure 4 shown, two reinforcing ribs 32 are provided, and the feed nozzle 4 is arranged between the two reinforcing ribs 32.
[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
