[0002] The traditional runner structure needs to set up more hollow positions to fix the injection molding related mechanisms. For example, the runner body, discharge nozzle, cylinder, etc. all need to be installed at the station, and the necessary accessories must be provided for the corresponding mechanisms. For example, it is necessary to provide the necessary oil circuit for the cylinder, or provide the control circuit and heating pipeline for the runner body. In this way, the traditional runner structure requires a large number of hollow areas to be designed. When there are too many hollow areas, the mechanical strength of the entire structure will decrease, so it is necessary to install multiple layers of solid plates.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish the described features, without distinction of order or importance. In the description of the present invention, unless otherwise specified, "multiple" means more than two.

[0049] like Figure 1-7 , a highly integrated mosaic injection molding runner, comprising: a solid back plate 1, a frame plate 2, a runner body 3, a discharge nozzle 4, a valve needle 5 and a driving cylinder 6;

[0050] One side of the frame plate 2 is fixed to one side of the solid back plate 1; the frame plate 2 is provided with a plate opening 21; one side of the flow channel body 3 is fixedly mounted on the solid back plate 1 and is located within the plate opening 21, with the outer edge of the flow channel body 3 and the inner wall of the plate opening 21 forming a buffer distance 22; the discharge nozzle 4 is mounted on the flow channel body 3 and is located on a side away from the solid back plate 1, and the valve needle 5 is movably mounted on the discharge nozzle 4;

[0051] The solid back plate 1 is provided with a cylinder receiving groove 13 for installing the driving cylinder 6 on a side away from the flow channel body 3; the output end of the driving cylinder 6 passes through the plate micropores of both the solid back plate 1 and the flow channel body 3, and is connected to the valve needle 5 at the end to drive the valve needle 5 to move; an oil passage 11 is provided inside the solid back plate 1, and the oil passage 11 is connected to the oil-using end of the driving cylinder 6.

[0052] This solution provides a highly integrated mosaic injection runner, which places the fixed position of the runner body 3 at the back of the solid backplate 1. The solid backplate 1 serves as the main fixed position of the runner body 3. The solid backplate 1 is also provided with an oil passage 11 inside. The injection runner of this solution can have the advantages of low thickness and high strength at the same time, solving the problems of high thickness requirements, low strength and inability to modularize the installation position of the existing injection runner.

[0053] Specifically, the frame plate 2 is installed on the solid backplate 1, and the frame plate 2 is provided with a plate opening 21, and the solid backplate 1 is located in the plate opening 21; the solid backplate 1 of this scheme is a solid structure, which only has a limited number and size of grooves, holes and other structures, such as the cylinder accommodating groove 13 and the oil channel 11, etc. Fewer grooves, holes and other structures will not cause the strength of the solid backplate 1 to decrease, so the solid backplate 1 can be regarded as a solid plate body; for the cylinder accommodating groove 13 of the solid backplate 1, the driving cylinder 6 is installed in the cylinder accommodating groove 13 on one side of the solid backplate 1, and the output end of the driving cylinder 6 only extends into the flow channel body 3 on the other side of the solid backplate 1 through the plate micropores on the bottom wall of the cylinder accommodating groove 13, so the solid backplate 1 does not have a large-area opening structure on the front and back sides, that is, the cylinder accommodating groove 13 used only for installing the driving cylinder 6 will not cause the overall strength of the solid backplate 1 to decrease. In this solution, both the frame plate 2 and the runner body 3 can be fixed to the solid backplate 1 using known fasteners, and the necessary fastening holes on the solid backplate 1 will not reduce the mechanical strength of the solid backplate 1. In particular, the frame plate 2 and the solid backplate 1 are fixed together, and the combined effect of the two can strengthen the overall mechanical strength of the injection molded runner. In this solution, the runner body 3 is directly mounted on the solid backplate 1 rather than being directly fixed to the frame plate 2. Only the necessary fastening holes need to be opened on the solid backplate 1. The solid portion of the solid backplate 1 can enhance the fixation stability of the runner body 3. At the same time, the oil passage 11 of the driving cylinder 6 of the present solution is located inside the solid back plate 1. The oil passage 11 is integrally formed when the solid back plate 1 is processed and formed. Therefore, the driving cylinder 6 does not need to be equipped with other pipelines to supply oil. It is only necessary to directly supply oil to one of the oil passages 11 to output the oil to the driving cylinder 6, and then discharge the oil through the other oil passage 11. Therefore, the driving cylinder 6 can be completely accommodated in the cylinder receiving groove 13, and no other mechanism will protrude from the surface of the solid back plate 1 on a large scale. Furthermore, the plate opening 21 of the frame plate 2 is surrounded by the flow channel body 3, and the outer edge of the flow channel body 3 and the inner wall of the plate opening 21 form a buffer distance 22. The buffer distance 22 can separate the inner wall of the plate opening 21 from the outer edge of the flow channel body 3, which can improve the protection of the flow channel body 3; that is, the frame plate 2 only exposes the flow channel body 3 and its discharge nozzle 4 and valve needle 5 in the plate opening 21, and the rest of the frame plate 2 is attached to the solid back plate 1; the solid back plate 1 and the frame plate 2 are overlapped to form a double-layer plate structure; and the double-layer plate structure is based on the advantage of high integration, and its surface does not have too many protruding structures, so the injection molding flow channel of this scheme has an inlay function, which can be directly inlaid and installed or disassembled in any injection molding device, realizing the modular installation of the injection molding flow channel and high flexibility in use.

[0054] Optimally, the method further includes: heating the metal member 7;

[0055] The outer surface of the flow channel body 3 is provided with a heating groove 31 along the outer edge; the heating metal member 7 is installed in the heating groove 31 and extends along the direction of the heating groove 31; the discharge nozzle 4 is arranged within the surrounding range of the heating groove 31.

[0056] This solution needs to consider the premise of a highly integrated structure and introduce a structure with a heating function to provide a heating function for the flow channel body 3 to ensure that the material in the flow channel body 3 has a certain fluidity when heated. To this end, this solution preferably uses a heating metal part 7 to provide a heating function for the flow channel body 3. Specifically, the flow channel body 3 is provided with a heating groove 31 along the outer edge, and the heating metal part 7 is installed in the heating groove 31. The heating metal part 7 is heated when powered on, and then the heat energy is transferred to the inside of the flow channel body 3; and the heating metal part 7 of this solution is distributed along the extension direction of the heating groove 31, and the discharge nozzle 4 is arranged in the surrounding range of the heating groove 31. The material will be heated before entering the discharge nozzle 4, and thus withdrawn through the discharge nozzle 4 at a specific temperature. In this way, the heating metal part 7 is directly installed on the outer surface of the flow channel body 3, and it will not occupy the space of the solid back plate 1 or the frame plate 2, thereby achieving a uniform heating effect under a highly integrated structure.

[0057] It can be optimized to further include: an external socket 8, a through frame 9 and a wire 10;

[0058] The frame plate 2 is provided with a socket slot 23 on the edge, and the socket slot 23 is connected to the plate opening 21 through the wire entry slot 24; the external socket 8 is located in the socket slot 23; the interior of the through-core frame 9 is a wire feeding through-core structure 90, and multiple through-core frames 9 are sequentially connected and distributed in the socket slot 23, the wire entry slot 24 and the buffer spacing 22; the wires 10 are distributed in the wire feeding through-core structure 90;

[0059] One end of some of the wires 10 is connected to the external socket 8 , and the other end of the wires 10 is connected to the heating metal member 7 .

[0060] The insertion slot 23 is arranged at the edge of the frame plate 2, which can be used to arrange the external insertion port 8, so that the external insertion port 8 does not protrude outside the outer walls of the solid back plate 1 and the frame plate 2, avoiding the protruding external insertion port 8 affecting the inlay. The present scheme will arrange the through frame body 9 between the insertion slot 23, the wire inlet slot 24 and the buffer spacing 22, and the wire feeding through structure 90 of the through frame body 9 can be used to accommodate the wire 10, and the wire 10 is connected with the heating metal piece 7 through the plurality of through frame bodies 9; one end of the wire 10 is connected with the external insertion port 8, and the external insertion port 8 only needs to be directly or indirectly connected with the power supply, so that the wire 10 is electrified, thereby electrifying the heating metal piece 7, and the heating metal piece 7 is heated under the action of electrification. The flow channel body 3. The buffer spacing 22 of the present scheme is mainly used to provide a buffer space for the frame plate 2 when the flow channel body 3 is heated and expanded, and the buffer spacing 22 is ingeniously used in the present scheme. The space is used to separate the wire 10 from the flow channel body 3 by using the through frame body 9 without affecting the buffering effect, which can avoid the wire 10 being heated when the flow channel body 3 is heated, and can fully utilize the buffer spacing 22 of the high-integration injection flow channel, thereby making the high-integration inlay type injection flow channel have both buffering function and heating function.

[0061] Optimally, part of the through frame body 9 is an L-shaped frame body 91; the L-shaped frame body 91 is arranged in the buffer spacing 22;

[0062] The L-shaped frame body 91 is provided with a frame body horizontal section 911 and a frame body vertical section 912, one vertical end of the frame body vertical section 912 is connected to one horizontal end of the frame body horizontal section 911; the L-shaped frame body 91 is arranged at the corner position of the flow channel body 3, and the frame body horizontal section 911 and the frame body vertical section 912 are respectively located at two adjacent side walls of the flow channel body 3.

[0063] The through frame body 9 of the present scheme can be designed in different forms according to the position; the L-shaped frame body 91 is arranged at the buffer spacing 22, and the L-shaped frame body 91 is arranged at the corner position of the flow channel body 3, so that the frame body horizontal section 911 and the frame body vertical section 912 are respectively located at two adjacent side walls of the flow channel body 3, which forms a frame structure at the outer edge of the flow channel body 3; and the inside of the through frame body 9 is the wire feeding through structure 90, which has a buffering effect and can protect the corners of the flow channel body 3 and provide a wire feeding function; at the same time, the wire feeding through structure 90 avoids the direct contact of the wire with the flow channel body 3, avoiding the melting of the outer glue layer of the wire when the flow channel body 3 is heated.

[0064] Optimally, one side of the L-shaped frame body 91 facing the flow channel body 3 is connected to the outer side wall of the flow channel body 3;

[0065] The horizontal section 911 of the frame and the vertical section 912 of the frame are respectively provided with a wire management gap 913 on the side away from the flow channel body 3, and the wire management gap 913 exposes the wire feeding core structure 90. The wire management gap 913 is close to the plate opening 21, and some of the wires 10 enter and exit the wire feeding core structure 90 through the wire management gap 913.

[0066] The L-shaped frame 91 of the present solution is arranged at the corner positions of the flow channel main body 3, and the corner positions are two adjacent outer side surfaces of the flow channel main body 3; the L-shaped frame 91 is directly connected to the outer side wall of the flow channel main body 3, rather than the frame plate 2, mainly based on the consideration of high integration. If the L-shaped frame 91 is installed on the solid back plate 1 or the frame plate 2, it will cause the entire injection molding flow channel to be installed inconveniently. For example, the L-shaped frame 91 is first installed on the solid back plate 1 or the frame plate 2, and then the flow channel main body 3 is installed. When installing the L-shaped frame 91, it is difficult to vertically extend the screwdriver into the wire feeding core structure 90 to tighten the screws for fixing. Therefore, it is often necessary to add a flat plate structure to the L-shaped frame 91, and then lock the flat plate structure to the solid back plate 1 or the frame plate 2 by screws. On the one hand, the present solution is a highly integrated structure, and the addition of a flat plate structure will increase the buffer spacing 22. The size and cost of the injection molding runner are increased, thereby increasing the cost of modular use. On the other hand, pre-installing the L-shaped frame 91 will make the runner body 3 inconvenient to install because the L-shaped frame 91 has surrounded the formed contour. Since the buffer spacing 22 is narrow, the runner body 3 needs to frequently adjust its own position and the position of part of the L-shaped frame 91 before and after installation on the solid backboard 1, resulting in a more complicated installation process for the runner body 3. In this solution, the L-shaped frame 91 is directly connected to the outer wall of the runner body 3. The L-shaped frame 91 can be fixed before installing the runner body 3, and then the runner body 3 is installed on the solid backboard 1, and finally the frame plate 2 is installed. The cumbersome installation brought about by the wiring structure for the highly integrated injection molding runner can be avoided. Therefore, the L-shaped frame 91 directly connected to the outer wall of the runner body 3 is the optimal embodiment.

[0067] At the same time, the L-shaped frame 91 of this solution exposes a wire management notch 913 on the outer side wall away from the flow channel body 3. When multiple L-shaped frames 91 are provided with a wire management notch 913, the wire 10 can be directly taken out of the wire management notch 913 and extended outside the L-shaped frame 91. Based on high integration, the wire 10 can be directly installed, sorted, debugged or replaced at the buffer spacing 22. It should be noted that the inner diameter of the side wall wire management notch 913 of the L-shaped frame 91 of this solution cannot be too large. If it is too large, it may make it impossible to limit the wire 10. It only needs to be opened according to the outer diameter of the wire 10.

[0068] Optimally, it further includes: frame screws 914;

[0069] The L-shaped frame 91 is provided with a fastening through hole 915 on the same side wall as the wire management notch 913, and the L-shaped frame 91 is provided with a screw fastening hole 916 on a side wall close to the flow channel main body 3; the frame screw 914 passes through the fastening through hole 915 and extends into the wire feeding through structure 90, and the screw of the frame screw 914 passes through the screw fastening hole 916 and is threadedly engaged with the outer wall of the flow channel main body 3.

[0070] Since the L-shaped frame 91 is set at the corner position of the flow channel body 3, based on the L-shaped through-core structure of the L-shaped frame 91, it is difficult to put the screw into the wire feeding through-core structure 90 and then tighten it, because it is difficult for the screwdriver to keep the same straight line with the frame screw 914 and the screw hole of the flow channel body 3; in this regard, Figure 7 The L-shaped frame 91 of this solution is provided with a fastening through hole 915 on the same side wall as the wire management notch 913. The screwdriver and its frame screw 914 can pass through the fastening through hole 915 normally. The fastening through hole 915 only needs to be designed to be slightly larger than the outer diameter of the screwdriver and the screw head of the frame screw 914. The frame screw 914 can then be threadedly engaged with the outer wall of the flow channel body 3 after the screw rod passes through the screw fastening hole 916, thereby solving the problem of difficult installation of the L-shaped frame 91.

[0071] Optimally, part of the through-core frame 9 is a transfer frame 93, and part of the through-core frame 9 is a socket frame 92;

[0072] The adapter frame 93 is arranged in the wire inlet groove 24; the socket frame 92 is located in the socket groove 23, and the external socket 8 is installed in the socket frame 92; the adapter frame 93 is provided with a connecting leg 921 at one end of the wire feeding through-core structure 90 thereof, and is connected to the socket frame 92 at the other end of the wire feeding through-core structure 90 thereof; the connecting leg 921 is detachably connected to the flow channel body 3, so that the external socket 8 is connected to the flow channel body 3 through the adapter frame 93;

[0073] The connecting leg 921 is provided with a leg hollow portion 922 , and the leg hollow portion 922 is connected to the wire feeding through-core structure 90 of one of the through-core frames 9 in the buffer interval 22 .

[0074] This solution uses through-core frames 9 of different structures in the socket slot 23, the wire entry slot 24 and the buffer spacing 22, respectively, and each through-core frame 9 is provided with a wire feeding through-core structure 90; for the through-core frame 9 of the wire entry slot 24, it is an adapter frame 93, and the adapter frame 93 has a connecting leg 921, which can be detachably mounted on the flow channel body 3, specifically, it can be magnetically fixed, snap-fit ​​fixed, clamped fixed, etc.; for example, a leg hole is provided on the connecting leg 921, and a screw hole is provided on the surface of the flow channel body 3, and the screw is passed through the leg hole and fixed to the screw hole, thereby realizing the detachable fixation of the connecting leg 921 on the flow channel body 3; the fixing position is preferably installed on the side of the flow channel body 3 at the plate opening 21; as Therefore, after the connecting leg 921 is fixed to the flow channel body 3, it can indirectly connect the socket frame 92 to the flow channel body 3, so that the external socket 8 is indirectly connected to the flow channel body 3 through the socket frame 92 and the adapter frame 93, and the external socket 8 does not need to be directly fixed to the solid back plate 1 and the frame plate 2; in this way, the socket frame 92 and its external socket 8 will not directly contact the solid back plate 1 and the frame plate 2, which can avoid the influence of the solid back plate 1 and the frame plate 2 on the external socket 8 when they are heated; at the same time, when it is necessary to replace the external socket 8 or other types of socket frames 92, the connecting leg 921 can be directly removed, and different types of external sockets 8 can be quickly replaced based on the highly integrated structure.

[0075] In addition, in addition to having a detachable fixing function, the connecting leg 921 can also transition the wire 10 of the socket frame 92 through the leg hollow portion 922 of the connecting leg 921 to the wire feeding core structure 90 of the L-shaped frame 91, thereby keeping the wire 10 regular.

[0076] Optimally, it further includes: a feed nozzle 12;

[0077] A nozzle opening 14 is provided in the middle of the solid back plate 1; the feed nozzle 12 is limited to the nozzle opening 14;

[0078] The flow channel main body 3 is provided with an I-shaped structure, and the I-shaped structure is provided with an I-shaped horizontal plate 32 and an I-shaped vertical plate 33 that are internally interconnected; the I-shaped vertical plate 33 is connected to the middle part of the I-shaped horizontal plate 32 at both ends in the length direction; the output end of the feed nozzle 12 is connected to the interior of the I-shaped vertical plate 33, for outputting materials to the I-shaped vertical plate 33; multiple discharge nozzles 4 are respectively installed on the I-shaped horizontal plate 32 and are connected to the interior of the I-shaped horizontal plate 32.

[0079] The flow channel main body 3 of this scheme preferably uses an I-shaped structure, that is, the I-shaped vertical plate 33 is respectively connected to the middle part of the I-shaped horizontal plate 32 at both ends in the length direction, and is distributed in the shape of an "I"; the I-shaped structure can be single or repeated in the flow channel main body 3; the advantage of the I-shaped structure is that the I-shaped structure is provided with an I-shaped horizontal plate 32 and an I-shaped vertical plate 33 that are internally interconnected, and the I-shaped vertical plate 33 can be used to connect the feed nozzle 12, and the material input by the feed nozzle 12 can diffuse to both ends and then transferred to the I-shaped horizontal plates 32 at both ends, and the material is then output to the outside through the discharge nozzle 4; in this way, the time when the material reaches each discharge nozzle 4 is almost the same, and the environment of the material passing through different discharge nozzles 4 is almost the same, ensuring that the discharge parameters of the material at different positions are close, and preventing differences between the same batch of materials; especially in the discharge nozzle 4 of this scheme, the valve needle 5 is independently controlled by a single driving cylinder 6, and when the material reaches the output end of the discharge nozzle 4, the driving cylinder 6 can be controlled as needed to control the material output. In this way, this solution can achieve high integration and multi-nozzle output.

[0080] Optimally, the input end and / or output end of the oil channel 11 is provided with an oil delivery socket 111, and the oil delivery socket 111 is detachably mounted on the outer side surface of the solid back plate 1;

[0081] An inner groove 15 is provided on part of the outer side surface of the solid back plate 1, and an inner wall of the inner groove 15 is provided with an inner groove through hole 16 connected to one of the oil passages 11; the inner groove 15 is used to accommodate the oil delivery sockets 111 of other solid back plates 1, and part of the oil delivery sockets 111 are close to or installed in the inner groove through hole 16.

[0082] When the injection molding runner of this solution is used alone or when the side is empty, the solid back plate 1 and the frame plate 2 can be equipped with an oil delivery socket 111 as needed, and the oil delivery socket 111 can input or output the oil of the driving cylinder 6; and this solution is a highly integrated mosaic structure, such as Figure 5 , when in use, multiple injection molding runners are generally used, so the injection molding runners may be set against each other when in use; in this regard, when the injection molding runners are against each other, the oil delivery socket 111 of one injection molding runner extends into the inner groove 15 of another injection molding runner, and the inner groove 15 of one injection molding runner is blocked by the side wall of the other injection molding runner, thereby sealing the inner groove 15; at the same time, when the oil delivery socket 111 of one injection molding runner extends into the inner groove 15 of another injection molding runner, the oil delivery socket 111 can be close to or installed in the through hole 16 in the groove, directly input or receive oil into the through hole 16 in the groove, so that the oil passes through the oil path 11 between the multiple solid back plates 1, thereby greatly simplifying the oil path structure of the multiple injection molding runners, and avoiding the oil path structure affecting the modular application. The injection molding runner of this scheme can achieve modular installation while having the advantages of low thickness and high strength.

[0084] The plurality of injection molding runners are arranged in sequence and installed on the frame.

[0085] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
