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 needs to design a large number of hollow areas. When there are too many hollow areas, the mechanical strength of the whole structure will decrease.

In the description of the present invention, unless otherwise specified, "multiple" means more than two.

[0049] like Figure 1-7 , a highly integrated inlaid injection molding flow channel, comprising: a solid back plate 1, a frame plate 2, a flow channel 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 in the plate opening 21, 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 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 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; the solid back plate 1 is provided with an oil passage 11 inside, and the oil passage 11 is connected to the oil-using end of the driving cylinder 6.

[0052] The present solution provides a highly integrated inlaid injection molding runner, which places the fixing position of the runner body 3 at the rear of the solid back plate 1. The solid back plate 1 serves as the main fixing position of the runner body 3. An oil passage 11 is also provided inside the solid back plate 1. The injection molding runner of the present solution can have the advantages of low thickness and high strength at the same time, which solves the problems of high thickness requirements, low strength and inability to modularize the installation position of the existing injection molding runner.

[0053] Specifically, the frame plate 2 is installed on the solid back plate 1, and the frame plate 2 is provided with a plate opening 21, and the solid back plate 1 is located in the plate opening 21; and the solid back plate 1 of the present 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 passage 11, etc., and fewer grooves, holes and other structures will not cause the strength of the solid back plate 1 to decrease, so the solid back plate 1 can be regarded as a solid plate body; for the cylinder accommodating groove 13 of the solid back plate 1, the driving cylinder 6 is installed in the cylinder accommodating groove 13 on one side of the solid back plate 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 back plate 1 through the plate micropores on the bottom wall of the cylinder accommodating groove 13, so the solid back plate 1 does not have a large area of ​​the 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 back plate 1 to decrease. The frame plate 2 and the flow channel body 3 of the present solution can be fixed to the solid back plate 1 by known fasteners, and the necessary fastening holes are provided on the solid back plate 1, which will not cause a decrease in the mechanical strength of the solid back plate 1. In particular, the frame plate 2 and the solid back plate 1 are fitted and fixed, and the combined effect of the two can strengthen the overall mechanical strength of the injection molding flow channel. The flow channel body 3 of the present solution is directly installed on the solid back plate 1 instead of being directly fixed to the frame plate 2, and it is only necessary to provide the necessary fastening holes on the solid back plate 1. The solid part of the solid back plate 1 can enhance the fixing stability of the flow channel body 3. At the same time, the oil passage 11 of the driving cylinder 6 of the present scheme 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 only needs 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 received in the cylinder receiving groove 13, and no other mechanism will protrude from the surface of the solid back plate 1 to a large extent. 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, thereby improving 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, and can be directly inlaid and installed or disassembled in any injection molding device, realizing the modular installation of the injection molding flow channel, and having high flexibility in use.

[0054] It can be optimized to further include: 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, so as to ensure that the material in the flow channel body 3 has a certain fluidity under the heated state. For this reason, 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 the power is turned 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 being passed into the discharge nozzle 4, so that it will be 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, so as to achieve 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 at 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 a plurality of through-core frames 9 are sequentially connected and distributed in the socket slot 23, the wire entry slot 24 and the buffering interval 22; the wire 10 is 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 piece 7 .

[0060] The socket slot 23 is arranged at the edge of the frame plate 2, and can be used to set the external socket 8, so that the external socket 8 will not extend beyond the outer wall of the solid back plate 1 and the frame plate 2, and the protruding external socket 8 will not affect the inlay. In this scheme, a through-core frame 9 is arranged between the socket slot 23, the wire entry slot 24 and the buffer spacing 22. The wire feeding through-core structure 90 of the through-core frame 9 can be used to accommodate the wire 10, and the wire 10 is connected to the heating metal part 7 after winding through multiple through-core frames 9; one end of the wire 10 is connected to the external socket 8, and the external socket 8 only needs to be directly or indirectly connected to the power supply to energize the wire 10, thereby energizing the heating metal part 7, and the heating metal part 7 heats the flow channel body 3 under the action of energization. The buffer spacing 22 of the present solution is mainly used to provide a buffer space for the frame plate 2 when the runner body 3 expands thermally. The present solution cleverly utilizes the space of the buffer spacing 22. The through frame 9 is used to separate the wire 10 from the runner body 3 without affecting the buffering effect. This can avoid heating of the wire 10 when the runner body 3 is heated, and can fully utilize the buffer spacing 22 of the highly integrated injection molding runner, so that the highly integrated mosaic injection molding runner has both buffering function and heating function.

[0061] It can be optimized that part of the through-core frame 9 is an L-shaped frame 91; the L-shaped frame 91 is arranged at the buffer distance 22;

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

[0063] The through-hole frame 9 of the present scheme can be designed into different shapes according to the position; the present scheme sets an L-shaped frame 91 at the position of the buffer spacing 22, and the L-shaped frame 91 is set at the corner position of the flow channel body 3, so that the frame transverse section 911 and the frame vertical section 912 are respectively located on two adjacent side walls of the flow channel body 3, which is equivalent to forming a frame structure at the outer edge of the flow channel body 3; and the interior of the through-hole frame 9 is a wire feeding through-hole structure 90, which has a buffering effect, can protect the corners of the flow channel body 3, and also provides a wire feeding function; at the same time, the wire feeding through-hole structure 90 prevents the wire from directly contacting the flow channel body 3, and prevents the outer rubber layer of the wire from melting when the flow channel body 3 is heated.

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

[0065] The frame transverse section 911 and the frame vertical section 912 are respectively provided with a wire management gap 913 on a 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 part 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 position of the flow channel body 3, and the corner position is the two adjacent outer side surfaces of the flow channel body 3; the L-shaped frame 91 is directly connected to the outer side wall of the flow channel 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 inconvenience of installing the entire injection molding flow channel. 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 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 installation 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 it inconvenient to install the runner body 3 because the L-shaped frame 91 has surrounded the formed contour. Since the buffer spacing 22 is relatively 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 being installed on the solid back plate 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 back plate 1, and finally the frame plate 2 is installed. The cumbersome installation caused 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 wire management notches 913, the wire 10 can be directly taken out of the wire management notch 913 and extended outside the L-shaped frame 91. The wire 10 can be directly installed, combed, debugged or replaced at the buffer interval 22 based on high integration. 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] It can be optimized to further include: 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 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 body 3.

[0070] Since the L-shaped frame 91 is disposed at the corner of the flow channel body 3, and 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 frame screw 914 and the screw hole of the flow channel body 3 in the same straight line; in this regard, Figure 7 The L-shaped frame 91 of the present invention 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 side 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] It can be optimized that 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 entry slot 24; the socket frame 92 is located in the socket slot 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 the other end of the wire feeding through-core structure 90 thereof is connected to the socket frame 92; 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] The present invention uses through-core frames 9 of different structures in the socket slot 23, the wire entry slot 24 and the buffer interval 22, respectively, and each through-core frame 9 is provided with a wire feeding through-core structure 90; the through-core frame 9 of the wire entry slot 24 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-fitted, clamped, 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; such as Therefore, after the connecting leg 921 is fixed to the flow channel body 3, it can make the socket frame 92 indirectly connected 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 the detachable fixing function, the connecting leg 921 can also transition the wire 10 of the socket frame 92 to the wire feeding structure 90 of the L-shaped frame 91 through the leg hollow portion 922 of the connecting leg 921 to keep the wire 10 regular.

[0076] It can be optimized to further include: 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 body 3 is provided with an I-shaped structure, and the I-shaped structure is provided with an I-shaped transverse plate 32 and an I-shaped vertical plate 33 which are internally interconnected; the two ends of the I-shaped vertical plate 33 are respectively connected to the middle part of the I-shaped transverse plate 32 in the length direction; the output end of the feed nozzle 12 is connected to the interior of the I-shaped vertical plate 33, and is used to output materials to the I-shaped vertical plate 33; the plurality of discharge nozzles 4 are respectively installed on the I-shaped transverse plate 32, and are connected to the interior of the I-shaped transverse plate 32.

[0079] The flow channel body 3 of the present scheme preferably uses an I-shaped structure, that is, the I-shaped vertical plates 33 are respectively connected to the middle of the I-shaped horizontal plates 32 at both ends in the length direction, and are distributed in the shape of an "I" character; the I-shaped structure can be single or repeated in the flow channel 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 be diffused 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 consistent, ensuring that the discharge parameters of the material at different positions are close to each other, and preventing differences between the same batch of materials; in particular, the valve needle 5 in the discharge nozzle 4 of the present scheme 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, the present solution can achieve multi-nozzle output on the basis of high integration.

[0080] Optimally, the input end and / or the output end of the oil passage 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 with the side 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, generally multiple injection molding runners are used, so the injection molding runners may be arranged side by side during use; in this regard, when the injection molding runners are side by side, the oil delivery socket 111 of one of the injection molding runners extends into the inner groove 15 of another injection molding runner, and the inner groove 15 of one of the injection molding runners 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 of the injection molding runners 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, and directly input or receive oil into the through hole 16 in the groove, so that the oil passes through the oil path channel 11 between the multiple solid back plates 1, thereby greatly simplifying the oil path structure of the multiple injection molding runners, avoiding the oil path structure from affecting the modular application, and 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] Although the 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 present invention, and that the scope of the present invention is defined by the claims and their equivalents.
