[0037] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.
[0038] like Figures 1 to 10As shown, the pipe clamping device 10 of this embodiment includes a clamping assembly, which includes at least two clamping blocks 1 for clamping the pipe 20. The at least two clamping blocks 1 are connected and form a plurality of cavities 11 through which the pipe 20 passes.
[0039] When in use, the pipe clamping device 10 of this embodiment clamps the pipe 20 between at least two clamping blocks 1, so that the pipe 20 is located in the cavity 11 surrounded by at least two clamping blocks 1. The clamping assembly clamps and fixes the pipe 20 to prevent the pipe 20 from loosening, thereby preventing leakage problems at the joints of the pipe 20.
[0040] In related technologies, die-casting molds include multiple pipelines, which are arranged in a disorderly manner. The pipelines are prone to bending, which reduces the flow rate and makes them prone to bursting at the bends. In addition, the pipelines squeeze each other, affecting the flow area and causing abnormal flow.
[0041] In some embodiments, such as Figure 1 , Figures 5 to 10 As shown, there are multiple cavities 11 to hold multiple pipes 20.
[0042] By setting multiple cavities 11, multiple pipes 20 are clamped by the multiple cavities 11, so that the multiple pipes 20 can be arranged in an orderly manner, avoiding bending and mutual compression of the pipes 20, thereby keeping the flow of the pipes 20 constant and preventing the pipes 20 from bursting.
[0043] Optionally, such as Figure 1 , Figures 5 to 10 As shown, multiple cavities 11 form multiple cavity groups, and the multiple cavity groups are arranged at intervals along a first direction. The same cavity group includes multiple cavities 11, and the multiple cavities 11 in the same cavity group are arranged at intervals along a second direction, which is perpendicular to the first direction.
[0044] For example, such as Figure 1 , Figures 5 to 7 As shown, the first direction is consistent with the vertical direction, the second direction is consistent with the horizontal direction, multiple cavity groups are arranged at intervals along the vertical direction, and multiple cavities 11 in the same cavity group are arranged at intervals along the horizontal direction. The number of cavity groups can be four, and each cavity group includes five cavities 11.
[0045] By arranging the multiple cavities 11 in the above manner, the arrangement of the multiple cavities 11 is orderly, thereby allowing the multiple pipes 20 to be arranged in an orderly manner.
[0046] Optionally, each cavity 11 extends along a third direction so that the conduit 20 passes through the cavity 11 along the third direction, which is perpendicular to the first direction.
[0047] For example, such as Figure 1 , Figures 5 to 7 As shown, the third direction is consistent with the front-to-back direction. Cavity 11 extends in the front-to-back direction, and pipe 20 extends in the front-to-back direction and passes through cavity 11.
[0048] By setting the extension direction of each cavity 11 to be consistent, the extension directions of multiple pipes 20 are the same, which can effectively prevent the pipes 20 from squeezing each other and keep the flow rate of the pipes 20 constant.
[0049] Optionally, multiple clamping blocks 1 are arranged sequentially along the first direction, and a cavity 11 is formed between two adjacent clamping blocks 1.
[0050] For example, multiple clamping blocks 1 are arranged sequentially in the vertical direction, and a cavity 11 is formed between two adjacent clamping blocks 1.
[0051] By arranging multiple clamping blocks 1 sequentially along the first direction, and forming a cavity 11 between two adjacent clamping blocks 1, the arrangement of the clamping blocks 1 is orderly, which facilitates the connection and fixation of the clamping blocks 1, thereby facilitating the assembly of the clamping assembly.
[0052] Optionally, such as Figure 1 , Figures 5 to 10 As shown, at least a portion of the clamping blocks 1 are the first clamping blocks 101. Figure 4 As shown, the first clamping block 101 has a clamping groove 1011 on one side in the first direction, and a clamping surface 1012 on the other side in the first direction. A cavity 11 is formed between two adjacent clamping blocks 1 through the clamping groove 1011 and the clamping surface 1012.
[0053] For example, there are five clamping blocks 1, four of which are the first clamping blocks 101. Figure 4 As shown, the first clamping block 101 has a clamping groove 1011 on its lower side and a clamping surface 1012 on its upper side. The clamping groove 1011 and the clamping surface 1012 located on its lower side form a cavity 11.
[0054] By providing a clamping groove 1011 on one side of the first clamping block 101 and a clamping surface 1012 on the other side of the first clamping block 101, and using the clamping groove 1011 and the clamping surface 1012 to form a cavity 11, the structure of the first clamping block 101 can be simplified, and the processing and manufacturing of the pipeline clamping device 10 can be facilitated.
[0055] Optionally, at least one clamping block 1 is a second clamping block 102, which is disposed on the same side of the first clamping block 101 in a first direction, with the opening of the clamping groove 1011 facing the second clamping block 102. The second clamping block 102 and the adjacent first clamping block 101 form a cavity 11 through the clamping groove 1011.
[0056] For example, there are five clamping blocks 1, one of which is the second clamping block 102. The clamping groove 1011 of the first clamping block 101 located on the upper side of the second clamping block 102 forms a cavity 11 with the second clamping block 102.
[0057] By setting a second clamping block 102, and the second clamping block 102 and the adjacent first clamping block 101 forming a cavity 11 through the clamping groove 1011, the structure of the second clamping block 102 can be simplified, and the processing and manufacturing of the pipeline clamping device 10 can be further facilitated.
[0058] Optionally, such as Figures 5 to 10 As shown, the clamping groove 1011 has an arc-shaped surface, which is used to fit against the pipe 20.
[0059] For example, the outer surface of the pipe 20 is a cylindrical surface, and the arc surface of the clamping groove 1011 is an arc surface, which fits against the pipe 20.
[0060] By setting an arc-shaped surface in the clamping groove 1011 and having the arc-shaped surface fit against the pipe 20, the contact area between the clamping groove 1011 and the pipe 20 can be increased, thereby improving the clamping stability of the clamping assembly on the pipe 20 and more effectively preventing the joints of the pipe 20 from loosening and preventing leakage problems in the pipe 20.
[0061] In some embodiments, two adjacent clamping blocks 1 are detachably connected.
[0062] By detachably connecting the clamping block 1, the clamping effect on the pipe 20 can be released by removing the clamping block 1, thereby facilitating the disassembly of the pipe 20.
[0063] Optionally, two adjacent clamping blocks 1 are connected by fasteners. For example... Figure 4 As shown, at least one clamping block 1 is provided with a threaded hole 12 for threaded connection with a fastener, and at least one clamping block 1 is provided with a countersunk hole 13 for the fastener to pass through.
[0064] For example, two adjacent clamping blocks 1 are connected by screws. Each clamping block 1 is provided with a threaded hole 12 and a countersunk hole 13. The threaded holes 12 and countersunk holes 13 in two adjacent clamping blocks 1 correspond one-to-one. The screw passes through the countersunk hole 13 and is threadedly connected to the threaded hole 12 to realize the connection and fixation between two adjacent clamping blocks 1.
[0065] By designing the clamping block 1 as described above, it is convenient to connect and disassemble two adjacent clamping blocks 1, thereby facilitating the assembly and disassembly of the pipeline clamping device 10.
[0066] Optionally, the clamping block 1 is arranged symmetrically along the second direction.
[0067] For example, clamping blocks 1 are arranged symmetrically in the left-right direction.
[0068] By arranging the clamping blocks 1 symmetrically along the second direction, the clamping blocks 1 can still be connected and fixed with the adjacent clamping blocks 1 after rotating 180°, which facilitates the connection and fixing of the clamping blocks 1 and thus facilitates the assembly of the pipeline clamping device 10.
[0069] In some embodiments, such as Figures 1 to 3 , Figures 5 to 10 As shown, the pipe clamping device 10 also includes a fixing member 2, which has a connecting part 213. The clamping assembly is detachably connected to the fixing member 2.
[0070] In practical use, the connecting part 213 can be fixed on the mold body to realize the connection and fixation between the pipeline clamping device 10 and the mold body.
[0071] By setting a fixing member 2 and a connecting part 213 on the fixing member 2, the clamping component can be detachably connected to the fixing member 2. The fixing member 2 can be used to connect the clamping component and the mold body, which facilitates the connection and fixation of the clamping component and the mold body.
[0072] Optionally, the connecting part 213 is a connecting hole.
[0073] Optionally, such as Figure 3 As shown, the fastener 2 is provided with multiple fixing positions 21, and the included angle between two adjacent fixing positions 21 is a preset angle α. The fixing positions 21 are used to fix the clamping components.
[0074] Where 'a' can be 5° to 10°.
[0075] By setting multiple fixed positions 21, and the clamps between two adjacent fixed positions 21 are at a preset angle, the orientation of the cavity 11 can be adjusted according to the direction of the pipeline 20, so as to avoid the pipeline 20 from bending, effectively keep the flow of the pipeline 20 constant, and prevent the pipeline 20 from bursting.
[0076] Optionally, such as Figure 3 As shown, the fixing position 21 is provided with a first fixing part 211 and a second fixing part 212, both of which are used to fix the clamping assembly. The first fixing parts 211 of the multiple fixing positions 21 overlap, and the line connecting the second fixing parts 212 of the multiple fixing positions 21 is an arc, the center of which coincides with the center of the first fixing part 211.
[0077] For example, both the first fixing part 211 and the second fixing part 212 are fixing holes, and the second clamping block 102 is connected to the fixing member 2 through a connector that is connected to the fixing hole.
[0078] By designing the fixing position 21 as described above, the clamping component can be connected to the first fixing part 211 and to different second fixing parts 212, so that the cavity 11 can be oriented differently, thereby making the orientation of the cavity 11 consistent with the direction of the pipeline 20, which makes it convenient to adjust the orientation of the cavity 11.
[0079] Optionally, such as Figure 1 , Figure 5 and Figure 8 As shown, there are multiple clamping components, which are arranged at intervals. There are multiple sets of fixing positions 21, and each set of fixing positions 21 corresponds to one clamping component.
[0080] For example, there are three clamping components and three sets of fixing positions 21, with each clamping component corresponding to one set of fixing positions 21.
[0081] By setting multiple clamping components, more pipes 20 can be clamped and fixed using the pipe clamping device 10 as needed, thereby improving the practicality of the pipe clamping device 10.
[0082] The pipe clamping device 10 of this embodiment separates and clamps multiple pipes 20 using clamping components, preventing the pipes 20 from intersecting or squeezing each other, thus avoiding flattening and maintaining a constant flow rate. The clamping components group the multiple pipes 20, fixing their direction and preventing bending, thus avoiding bursting at bends. The clamping components are fixed to the fixing member 2, facilitating adjustment of the orientation of the cavity 11 so that the direction of the pipes 20 aligns with the orientation of the cavity 11. The clamping blocks 1 are symmetrically arranged along the second direction and can be stacked by rotating 180°, reducing the structural complexity of the clamping blocks 1. The clamping components are made of aluminum alloy, which is lightweight, has good structural strength, and excellent processing performance. The first clamping block 101 has a clamping groove 1011, which facilitates pipe 20 installation while increasing the clamping area and improving the clamping stability of the pipes 20.
[0083] The die-casting mold of this embodiment includes a mold body, multiple pipes and a pipe clamping device 10. The pipe clamping device 10 is any of the pipe clamping devices 10 described above. The pipe clamping device 10 is connected to the mold body, and the pipe 20 passes through the cavity 11.
[0084] The fixing component 2 can be connected to the mold body via a connector to achieve the connection and fixation between the pipe clamping device 10 and the mold body. The connector can be a bolt, screw, etc.
[0085] After the pipe 20 is clamped by the clamping component, the pipe 20 can move without shaking during the movement of the die-casting mold, and there will be no situation where the joint of the pipe 20 becomes loose and causes leakage.
