Description

Technical Field

[0001] The utility model relates to the technical field of hot runner processing, and more specifically, to an assembled manifold plate. Background Art

[0002] Hot runner systems are increasingly common in the mold industry for injection molding pipe products. These systems typically consist of a manifold and a mold body. The manifold has an inlet, multiple outlets, and multiple flow channels connecting the inlets and outlets. The manifold's inlet is used to inject hot fluid material, while the manifold's outlets connect to the inlets of the mold body. After being divided by the manifold, the hot fluid material can be injected into the various molding cavities of the mold body, improving production efficiency.

[0003] Existing manifolds are usually one-piece molded structures, with flow channels opened inside the manifold. To process the above-mentioned manifold, it is necessary to first open multiple machining holes in different directions on the side wall of the manifold. The axial direction of each machining hole is consistent with the extension direction of the corresponding flow channel. Then, a drill bit is inserted through the machining hole to open the flow channel. After completion, the machining hole needs to be sealed with a plunger. Finally, grooves need to be cut at the corners of each flow channel and inserts installed. The inserts have flow channels with rounded corners that are connected to the flow channels of the manifold. The entire manifold manufacturing process is relatively complicated. Since the flow channels are opened inside the manifold, it is difficult to polish the flow channels. In addition, if the flow channels are too long, it is difficult for the drill bit to be inserted, making drilling inconvenient. Utility Model Content

[0004] In order to overcome the problem of inconvenient polishing and drilling of flow channels of the diverter plate in the above-mentioned prior art, the utility model provides an assembled diverter plate to facilitate polishing and drilling of the flow channels, thereby improving work efficiency and reducing costs.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an assembled diverter plate, having a main channel and several branch channels connected to the main channel, the main channel is provided with an inlet, and each branch channel is provided with an outlet, the diverter plate includes an upper template and a lower template, the upper template and the lower template are detachably connected, an upper channel groove is provided on one side of the upper template, and a lower channel groove is provided on one side of the lower template corresponding to the position of the upper channel groove, the upper channel groove and the lower channel groove are spliced along the axial cross section to form the main channel and each branch channel.

[0006] In the technical solution of the present invention, the fluid material enters the diverter plate from the inlet, and is diverted through the main channel and each branch channel. The diverter plate includes an upper template and a lower template, so the upper template and the lower template can be processed and manufactured separately during production. Since the upper template and the lower template are respectively provided with an upper flow channel groove and a lower flow channel groove that are spliced along the axial cross section, the upper flow channel groove and the lower flow channel groove are open-type groove structures before being spliced, so they can be processed directly on the surface of the upper template and the lower template, and the processing process is convenient. The diverter plate of the utility model does not require additional drilling of processing holes when opening the flow channel, and does not need to use plugs to seal the processing holes after assembly is completed, saving material costs. When it is necessary to polish the main channel and the branch channel again or expand the flow channel cross section, it is only necessary to separate the upper template and the lower template for processing, and the processing process is convenient.

[0007] Furthermore, the central axes of the main channel and each of the branch channels are located on the same horizontal plane.

[0008] In the above technical solution, since the central axes of the main channel and each branch channel are located on the same horizontal plane, the upper channel groove and the lower channel groove are also located on the same plane, so as to facilitate the grooving of the upper template and the lower template.

[0009] Furthermore, the upper template is provided with a limiting portion, and the lower template is provided with a positioning portion, and the limiting portion and the positioning portion are in contact with each other.

[0010] In the above technical solution, the limiting portion and the positioning portion are used to facilitate rapid positioning of the upper template and the lower template, so as to facilitate splicing to form the diverter plate.

[0011] Furthermore, the limiting portion is a limiting groove, the positioning portion is a positioning block, and the positioning block is matched and placed in the limiting groove.

[0012] In the above technical solution, the limiting groove and the positioning block can match and abut against each other to prevent the upper template and the lower template from deviating along the connection surface direction.

[0013] Furthermore, the diverter plate further includes a fastener, one end of the fastener is connected to the upper template, and the other end of the fastener is connected to the lower template.

[0014] In the above technical solution, the upper template and the lower template can be further connected by fasteners to prevent deviation and loosening.

[0015] Furthermore, the fasteners are bolts, the upper template is provided with a plurality of threaded holes, the lower template is provided with a plurality of through holes corresponding to the positions of the threaded holes, or the upper template is provided with a plurality of through holes, the lower template is provided with a plurality of threaded holes corresponding to the positions of the through holes; each threaded hole and the corresponding through hole are connected by the bolts.

[0016] In the above technical solution, the upper template and the lower template are detachably connected by means of bolts passing through the threaded holes and the through holes, which can ensure a stable connection and facilitate disassembly.

[0017] Furthermore, the cross sections of the upper flow channel groove and the lower flow channel groove are both semicircular.

[0018] In the above technical solution, since the cross-sections of the upper flow channel groove and the lower flow channel groove are both semicircular, the upper flow channel groove and the lower flow channel groove are easier to process, and after assembly, the main flow channel and the branch flow channel with circular cross-section are formed to facilitate the flow of fluid materials.

[0019] Furthermore, the branch channels are symmetrically arranged on both sides of the main channel.

[0020] In the above technical solution, since the branch channels are symmetrically arranged on both sides of the main channel, the fluid material can be evenly diverted from the main channel to the branch channels on both sides.

[0021] Furthermore, the inlet is opened in the upper template.

[0022] In the above technical solution, the fluid material can enter the main flow channel of the manifold from the inlet of the upper template.

[0023] Furthermore, the outlet is opened in the lower template.

[0024] In the above technical solution, the fluid material can flow out from the outlet of the lower template through each branch channel.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The assembled manifold of the present invention has an upper flow channel groove and a lower flow channel groove respectively formed on the upper template and the lower template, which are connected along the axial cross section. Therefore, the upper flow channel groove and the lower flow channel groove are open-type groove structures before being connected. Therefore, they can be processed directly on the surface of the upper template and the lower template, which is convenient for processing. The manifold of the present invention does not require additional drilling holes when opening the flow channel, and does not require the use of plungers to seal the processing holes after assembly, thus saving material costs. When the main channel and the branch channel need to be polished again or the flow channel cross section needs to be expanded, it is only necessary to separate the upper template and the lower template for processing, which is convenient for processing.

[0027] 2. Since the upper template is provided with a limiting part and the lower template is provided with a positioning part, the limiting part and the positioning part abut against each other, and the upper template and the lower template can be quickly positioned through the limiting part and the positioning part, which is convenient for splicing to form a diverter plate.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0036] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0037] Example 1

[0038] refer to Figure 1 、 Figure 3 and Figure 5The present embodiment discloses an assembled diverter plate, which has a main channel 1 and several branch channels 2 connected to the main channel 1. The main channel 1 is provided with an inlet 11, and each branch channel 2 is provided with an outlet 21. The diverter plate includes an upper template 3 and a lower template 4. The upper template 3 and the lower template 4 are detachably connected. An upper channel groove 31 is provided on one side of the upper template 3, and a lower channel groove 41 is provided on one side of the lower template 4 corresponding to the position of the upper channel groove 31. The upper channel groove 31 and the lower channel groove 41 are spliced along the axial cross section to form the main channel 1 and each branch channel 2.

[0039] Specifically, an upper runner groove 31 is defined on the lower plane of the upper mold plate 3, and a lower runner groove 41 is defined on the upper plane of the lower mold plate 4. Both the upper runner groove 31 and the lower runner groove 41 are open-type groove structures. When the upper mold plate 3 and the lower mold plate 4 are joined to form the manifold, the upper runner groove 31 and the lower runner groove 41 are joined to form the main runner 1 and the branch runner 2. The joined main runner 1 and branch runner 2 are located inside the manifold.

[0040] refer to Figure 1 and Figure 5 , Figure 1 Shown is the back edge of the upper template 3 and the lower template 4. Figure 1 The upper flow channel groove 31 and the lower flow channel groove 41 are spliced along the axial cross section, where the axial cross section refers to the cross section where the axis of the main flow channel 1 and each branch flow channel 2 is located, that is, Figure 5 The middle plane where the upper template 3 and the lower template 4 contact.

[0041] In this embodiment, the fluid material enters the diverter plate from the inlet 11 and is diverted through the main channel 1 and the branch channels 2. The diverter plate includes an upper template 3 and a lower template 4, so the upper template 3 and the lower template 4 can be processed and manufactured separately during production. Since the upper template 3 and the lower template 4 are each provided with an upper flow channel groove 31 and a lower flow channel groove 41, and the upper flow channel groove 31 and the lower flow channel groove 41 are open groove structures before splicing, processing can be performed directly on the surface of the upper template 3 and the lower template 4, which facilitates the processing process.

[0042] The manifold of the present invention does not require additional drilling when creating flow channels, nor does it require plugging to seal the holes after assembly. When the main channel 1 and branch channel 2 need to be re-processed, the upper and lower templates 3 and 4 can be separated for processing, making the processing process convenient.

[0043] In this embodiment, the central axes of the main channel 1 and each branch channel 2 are all located on the same horizontal plane. Specifically, the plane where the central axes of the main channel 1 and each branch channel 2 are located is also the plane where the upper template 3 and the lower template 4 are connected. In this way, the upper channel groove 31 can be opened at the same plane height position of the upper template 3, making processing easier, and the same applies to the lower template 4. Since the central axes of the main channel 1 and each branch channel 2 are all located on the same horizontal plane, the upper channel groove 31 and the lower channel groove 41 are also respectively located on the same plane, so as to facilitate the grooving processing of the upper template 3 and the lower template 4.

[0044] In other embodiments, the horizontal planes where the central axis of the main channel 1 and the central axis of the branch channel 2 are located may also be staggered, that is, the horizontal heights of the main channel 1 and the branch channel 2 are different, and the main channel 1 may be higher than the height of the branch channel 2, and the end of the main channel 1 may extend downward to connect with the branch channel 2. Convex or concave portions along the extension direction of the main channel 1 and the branch channel 2 will be formed on the lower side surface of the upper template 3 and the upper side surface of the lower channel. Although the processing of the upper channel groove 31 and the lower channel groove 41 is slightly complicated, it can play a certain role in limiting the position in the lateral direction, preventing lateral displacement after the upper template 3 and the lower template 4 are connected.

[0045] Preferably, the cross-sections of the upper runner groove 31 and the lower runner groove 41 are both semicircular. Specifically, the upper runner groove 31 and the lower runner groove 41 are spliced together to form a complete circular cross-section runner. Because the cross-sections of the upper runner groove 31 and the lower runner groove 41 are both semicircular, they are easier to process. After assembly, the main runner 1 and the branch runner 2, each with a circular cross-section, facilitate the flow of fluid materials.

[0046] It is understood that the semicircular cross-section refers to the cross-sectional shape of the portion where the upper flow channel 31 and the lower flow channel 41 flow independently. If it is located at the intersection of the main channel 1 and the branch channel 2 or the intersection of different branch channels 2, its cross-sectional shape will naturally be slightly changed according to the connection requirements.

[0047] Each branch channel 2 is symmetrically arranged on both sides of the main channel 1. Specifically, the main channel 1 is set in the middle of the diverter plate, and is connected to a branch channel 2 on both sides of the main channel 1. The branch channels 2 on both sides are further symmetrically connected to multiple branch channels 2, forming multiple groups of symmetrical branch channels 2.

[0048] For example, in this embodiment, the direction shown in the figure is taken as an example for illustration. The first branch channel is symmetrically arranged on the left and right sides of the main channel 1, the second branch channel is symmetrically arranged on both sides of the first branch channel, and the third branch channel is symmetrically arranged on both sides of the second branch channel. The third branch channel is arranged in a roughly X-shaped shape, and the second branch channel is connected to the center position of the X-shape. Finally, a structural form is formed in which eight third branch channels are arranged symmetrically on both sides of the main channel 1, with a total of sixteen third branch channels. An outlet 21 is provided at the end of each third branch channel, so that the fluid material entering from the inlet 11 of the main channel 1 can be evenly distributed to the outlet 21 of each branch channel 2.

[0049] In this embodiment, an inlet 11 is provided in the upper mold plate 3, and an outlet 21 is provided in the lower mold plate 4. Specifically, the inlet 11 is located on the upper side of the upper mold plate 3, and the outlet 21 is located on the lower side of the lower mold plate 4. Fluid material enters the main channel 1 of the manifold through the inlet 11 of the upper mold plate 3, then flows through the branch channels 2 and out through the outlet 21 of the lower mold plate 4.

[0050] Example 2

[0051] refer to Figures 1 to 4 This embodiment is similar to embodiment 1, except that in this embodiment, the upper template 3 is provided with a limiting portion 5, and the lower template 4 is provided with a positioning portion 6, and the limiting portion 5 and the positioning portion 6 are in contact with each other.

[0052] Multiple sets of stoppers 5 and positioning members 6 can be provided, distributed around and in the center of the upper and lower templates 3 and 4, respectively, to achieve effective positioning. The stoppers 5 can be grooves, holes, or shoulders, while the positioning members 6 can be matching protrusions, columns, or shoulders. The stoppers 5 and positioning members 6 facilitate quick positioning of the upper and lower templates 3 and 4, facilitating their assembly to form the manifold.

[0053] Optionally, in this embodiment, the limiting portion 5 is a limiting groove, and the positioning portion 6 is a positioning block, which is inserted into the limiting groove. Of course, in other embodiments, the upper template 3 may be provided with the positioning portion 6, and the lower template 4 may be provided with the limiting portion 5 (not shown in the figure).

[0054] More specifically, there are five limit grooves and positioning blocks, which are arranged at the four corners and the middle of the upper template 3 and the lower template 4. The limit grooves and the positioning blocks can match and abut to prevent the upper template 3 and the lower template 4 from deviating in the horizontal direction.

[0055] Example 3

[0056] refer to Figure 1 and Figure 3This embodiment is similar to Embodiment 1, except that the manifold further includes a fastener, one end of which is connected to the upper mold plate 3 and the other end of which is connected to the lower mold plate 4. The fastener can be a bolt, stud, or screw. The fastener further connects the upper mold plate 3 and the lower mold plate 4 to prevent them from deviating or loosening.

[0057] Preferably, in this embodiment, the fasteners are bolts. The upper template 3 is provided with a plurality of threaded holes 7, and the lower template 4 is provided with a plurality of through holes 8 corresponding to the positions of the threaded holes 7. Each threaded hole 7 is connected to the corresponding through hole 8 by a bolt. Of course, in other embodiments, the upper template 3 may be provided with a plurality of through holes 8, and the lower template 4 may be provided with a plurality of threaded holes 7 corresponding to the positions of the through holes 8. The other end of the bolt located in the threaded hole 7 can be reinforced with a nut to prevent loosening. The bolts passing through the threaded holes 7 and through holes 8 provide a detachable connection between the upper template 3 and the lower template 4, ensuring a stable connection while facilitating disassembly.
