Description

Technical Field

[0001] This invention relates to the technical field of automotive parts production, and in particular to a hot runner system, injection mold, and production equipment for automotive parts production. Background Technology

[0002] In the automotive parts manufacturing industry, injection molds are used to mold products. However, when injection molding automotive parts such as snap-fit ​​components, different injection molds are required because the snap-fit ​​pins and snap-fit ​​seats are made of different materials. Each injection mold is equipped with a separate hot runner system to complete the injection molding of both the snap-fit ​​pins and snap-fit ​​seats. In other words, the hot runner systems for producing the snap-fit ​​pins and snap-fit ​​seats are located in two separate injection molds. This process results in higher production costs and a larger space requirement for snap-fit ​​components. Summary of the Invention

[0003] This invention provides a hot runner system for the production of automotive parts, which solves the problems of high production costs and large space occupation in the injection molding process of snap-fit ​​components in automotive parts.

The second flow channel structure includes a second main flow channel and a plurality of second branch flow channels. The plurality of second branch flow channels are arranged on both sides of the first flow channel structure and are all connected to the second main flow channel. There is a gap between the second main flow channel and the first flow channel structure, and there is a gap between the second branch flow channels on both sides and the first flow channel structure.

[0010] The connection path between the first glue inlet flow path and the first flow channel structure is independent of the connection path between the second glue inlet flow path and the second flow channel structure.

[0011] According to an embodiment of the present invention, in a hot runner system for the production of automotive parts, the second runner structure is arranged to surround at least a portion of the first runner structure.

Each second branch channel is provided with at least one second branch end, and each second branch end is connected to a corresponding second branch channel. The second branch channel has a plurality of second branch outlets distributed along its length direction.

[0013] According to an embodiment of the hot runner system for automotive parts production, the distance from each second branch position to the second glue inlet path is equal; the distance from each second branch end to the second branch position is equal.

[0014] The second branch end is connected to the middle part of the second branch channel.

Each first branch channel has two first branch ends, and each first branch end is connected to a first branch channel. Multiple first branch outlets are evenly distributed along the length of the first branch channel.

[0018] According to an embodiment of the present invention, in a hot runner system for automotive parts production, the distance from each first branch point to the first glue inlet path is equal; and the distance from each first branch end to the first branch point is equal.

[0019] The first branch end is connected to the middle part of the first branch channel.

[0020] According to an embodiment of the present invention, in a hot runner system for automotive parts production, the centerline of the first glue inlet flow path is perpendicular to the centerline of the second glue inlet flow path.

[0021] An injection mold for producing automotive parts according to a second aspect embodiment of the present invention includes:

[0022] First template;

[0023] The hot runner system for automotive parts production described in any of the above embodiments is disposed in the first template;

[0024] The second template is adapted to move relative to the first template to a mold-closing state or a demolding state.

There is a gap between the second main runner and the first runner structure, and there is also a gap between the second branch runners on both sides and the first runner structure. This achieves a staggered arrangement of the first and second runner structures, maximizing their spatial cooperation, resulting in a compact structure and reduced space occupation. On the other hand, the gap between the second main runner and the first runner structure, as well as the gap between the second branch runners on both sides and the first runner structure, avoids heat transfer between the first and second runner structures. This is suitable for the separate injection molding of two materials with different melting points. In this way, the first and second runner structures can be integrated into the same hot runner system, reducing space occupation. Attached Figure Description

[0047] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0048] In the description of the embodiments of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention based on the specific circumstances.

[0050] In embodiments of the present invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0052] The following is combined with Figures 1-11 The present invention describes a hot runner system, injection mold, and production equipment for the production of automotive parts.

[0053] One aspect of the embodiments of the present invention, with reference to Figure 1 and Figure 2 As shown, a hot runner system for automotive parts production is provided, including a first injection flow path 310, a second injection flow path 320, a first flow channel structure 100, and a second flow channel structure 200. The first flow channel structure 100 is connected to the first injection flow path 310 for conveying a first injection molding material, and the second flow channel structure 200 is connected to the second injection flow path 320 for conveying a second injection molding material. The second flow channel structure 200 includes a second main flow channel 210 and a plurality of second branch flow channels 220. The plurality of second branch flow channels 220 are disposed on both sides of the first flow channel structure 100, and each of the plurality of second branch flow channels 220 is connected to the second main flow channel 210. There is a gap between the second main flow channel 210 and the first flow channel structure 100, and there is also a gap between the second branch flow channels 220 on both sides and the first flow channel structure 100. The connection path between the first injection flow path 310 and the first flow channel structure 100 is independent of the connection path between the second injection flow path 320 and the second flow channel structure 200.

[0054] It is understandable that, in this embodiment, in combination with Figure 2 and Figure 3 As shown, the second runner structure 200 includes a second main runner 210 and multiple second branch runners 220. The multiple second branch runners 220 are arranged on both sides of the first runner structure 100, and all of the multiple second branch runners 220 are connected to the second main runner 210. There is a gap between the second main runner 210 and the first runner structure 100, and there is also a gap between the second branch runners 220 on both sides and the first runner structure 100. This achieves a staggered arrangement of the first runner structure 100 and the second runner structure 200, allowing them to cooperate with each other to the greatest extent in space, resulting in a compact structure and reduced space occupation. On the other hand, the gap between the second main runner 210 and the first runner structure 100, and the gap between the second branch runners 220 on both sides and the first runner structure 100, avoids heat transfer between the first runner structure 100 and the second runner structure 200. This is suitable for the separate injection molding of two materials with different melting points. In this way, the first runner structure 100 and the second runner structure 200 can be integrated into the same hot runner system, reducing the space occupation.

[0055] For example, the first flow channel structure 100 is connected to the first injection flow path 310 for conveying the first injection material to form the first workpiece A, and the second flow channel structure 200 is connected to the second injection flow path 320 for conveying the second injection material to form the second workpiece B, so that the forming of the first workpiece A and the second workpiece B can be realized simultaneously.

[0056] According to an embodiment of the present invention, reference Figure 3 As shown, the second flow channel structure 200 is arranged around at least a portion of the first flow channel structure 100.

[0057] It is understandable that by adopting the above structure, the space of the hot runner system can be utilized to the greatest extent and in a more rational manner, making the structure more compact, which is conducive to reducing the volume of the hot runner system, making the hot runner system smaller, and reducing manufacturing costs. Of course, the above-mentioned first runner structure 100 can also be arranged around all areas of the second runner structure 200, that is, the first runner structure 100 surrounds the second runner structure 200 in a ring shape. It can be designed and adjusted according to specific production needs, and this embodiment does not make specific limitations in this regard.

[0058] According to one embodiment of the present invention, in combination Figure 2 , Figure 3 and Figure 4 As shown, the second main channel 210 is provided with a plurality of second branch positions 211, and the plurality of second branch positions 211 correspond one-to-one with and are connected to the plurality of second branch channels 220. Each second branch channel 220 is provided with at least one second branch end 221, and each second branch end 221 is connected to a corresponding second branch channel 222. The second branch channel 222 has a plurality of second branch outlets 2221 distributed along its length direction.

[0059] Understandably, each second branch port 2221 can be connected to a corresponding second forming chamber 430, enabling the simultaneous forming of multiple second workpieces B at different locations, thus improving production efficiency and the flexibility of multi-workpiece processing. Each second branch port 2221 is connected to a second forming chamber 430, allowing the forming process of the second workpiece B to proceed independently, and the second forming chambers 430 are isolated from each other, avoiding interference between the second workpieces B.

[0060] According to one embodiment of the present invention, in combination Figure 2 , Figure 3 and Figure 4 As shown, the distance from each second branch position 211 to the second glue inlet path 320 is equal; the distance from each second branch end 221 to the second branch position 211 is equal; wherein, the second branch end 221 is connected to the middle of the second branch channel 222.

[0061] It is understood that in this embodiment, by making the distance from each second branch position 211 to the second injection path 320 equal, and the distance from each second branch end 221 to the second branch position 211 equal, the distance of the injection molding material from the second injection path 320 to each second branch end 221 is equal, and thus the distance to each second molding chamber 430 is approximately equal. Under the condition that the injection flow rate, speed and other parameters are the same, the injection time of each second molding chamber 430 is basically consistent, ensuring that the injection material in each second molding chamber 430 is filled evenly, avoiding excessive differences in product size, appearance, density, etc., improving the consistency and stability of product quality, and improving production efficiency.

[0062] Furthermore, the centerline of the second inlet flow path 320 is perpendicular to the centerline of the second main flow path 210, the centerline of the second branch position 211 is perpendicular to the centerline of the second branch channel 220, the centerline of the second branch end 221 is perpendicular to the centerline of the second branch channel 222, and the centerline of the second branch outlet 2221 is perpendicular to the centerline of the second branch channel 222. Through the above arrangement, the adhesive material has vertical movement when flowing in the straight plane direction, which causes the adhesive material to tumble. This makes the temperature of the adhesive material passing through the second flow channel structure 200 uniform, which is beneficial to pressure equalization. Furthermore, it makes the adhesive material evenly injected into each second molding chamber 430, which is beneficial to keep the time of the adhesive fluid entering each first molding structure through the second flow channel structure 200 consistent.

[0063] According to one embodiment of the present invention, in combination Figure 2 , Figure 3 , Figure 4 and Figure 11 As shown, the first flow channel structure 100 includes a first main flow channel 110 and a first branch flow channel 120. The first main flow channel 110 is provided with a plurality of first branch positions 111. The plurality of first branch flow channels 120 correspond one-to-one with the plurality of first branch positions 111 and are connected. The first branch flow channel 120 is provided with two first branch ends 121. Each first branch end 121 is connected to a first branch flow channel 122. The first branch flow channel 122 has a plurality of first branch outlets 1221 evenly distributed along its length direction.

[0064] It is understood that in this embodiment, each first branch port 1221 can be connected to a corresponding first forming chamber 420, enabling the simultaneous forming of multiple first workpieces A at different locations, thereby improving production efficiency and the flexibility of multi-workpiece processing. Each first branch port 1221 is connected to a first forming chamber 420, allowing the forming process of the first workpiece A to proceed independently, and the first forming chambers 420 are isolated from each other, avoiding interference between the first workpieces A.

[0065] According to one embodiment of the present invention, in combination Figure 2 , Figure 3 and Figure 4 As shown, the distance from each first branch position 111 to the first glue inlet path 310 is equal; the distance from each first branch end 121 to the first branch position 111 is equal; wherein, the first branch end 121 is connected to the middle of the first branch channel 122.

[0066] It is understood that in this embodiment, by making the distance from each first branch position 111 to the first injection path 310 equal, and the distance from each first branch end 121 to the first branch position 111 equal, the distance of the injection molding material from the first injection path 310 to each first branch end 121 is equal, and thus the distance to each first molding chamber 420 is approximately equal. Under the condition that the injection flow rate, speed and other parameters are the same, the injection time of each first molding chamber 420 is basically consistent, ensuring that the injection material in each first molding chamber 420 is filled evenly, avoiding excessive differences in product size, appearance, density, etc., improving the consistency and stability of product quality, and improving production efficiency.

[0067] Furthermore, the centerline of the first inlet flow path 310 is perpendicular to the centerline of the first main flow channel 110, the centerline of the first branch position 111 is perpendicular to the centerline of the first branch channel 120, the centerline of the first branch end 121 is perpendicular to the centerline of the first branch channel 122, and the centerline of the first branch outlet 1221 is perpendicular to the centerline of the first branch channel 122. Through the above arrangement, the adhesive material has vertical movement when flowing in the straight plane direction, which causes the adhesive material to tumble. This makes the temperature of the adhesive material passing through the first flow channel structure 100 uniform, which is beneficial to pressure equalization. Furthermore, it makes the adhesive material evenly injected into each first molding chamber 420, which is beneficial to keep the time of the adhesive fluid entering each first molding structure through the first flow channel structure 100 consistent.

[0068] According to an embodiment of the present invention, reference Figure 4 As shown, the center line of the first glue inlet path 310 is perpendicular to the center line of the second glue inlet path 320.

[0069] It is understood that in this embodiment, by making the center line of the first injection path 310 perpendicular to the center line of the second injection path 320, the two paths can be made independent of each other in the horizontal direction, thereby achieving a more precise and controllable injection molding process. This helps to avoid interference between the first injection path 310 and the second injection path 320 during injection, which can improve the efficiency and stability of injection molding, reduce production line downtime and debugging time caused by interference, and improve production efficiency.

[0070] In some embodiments, reference Figure 4 and Figure 5 As shown, the first mold plate 300 is provided with a first injection port 370 and a second injection port 380. The first injection port 370 is connected to the first injection flow path 310, and the second injection port 380 is connected to the second injection flow path 320. Two injection molding materials are injected from the first injection port 370 and the second injection port 380 respectively, realizing the production of two different automotive parts on the same injection mold, namely molding the first workpiece A (e.g., a caliper pin) and molding the second workpiece B (e.g., a caliper seat). This helps to reduce production costs and space occupation. Moreover, since the two materials have their own independent connection paths, it helps to avoid interference between the first workpiece A and the second workpiece B during the injection molding process.

[0071] It is understood that in some embodiments of the present invention, such as Figure 5 As shown, the first template 300 has a first plate surface and a second plate surface. A first injection port 370 is located on the first plate surface, and a second injection port 380 is located on the second plate surface; wherein the first plate surface and the second plate surface are perpendicular to each other. Accordingly, it can be understood that in this embodiment, the first injection port 370 is located on the side wall plate surface of the first template 300, and the second injection port 380 is located on the top plate surface of the first template 300. Through the above structure, it is beneficial to avoid interference between the first injection port 370 and the second injection port 380 during injection, which can improve the efficiency and stability of injection molding, reduce production line downtime and debugging time caused by interference, and improve production efficiency.

[0072] Of course, the first glue inlet 370 and the second glue inlet 380 are not limited to being located at different positions on the first template 300. The first glue inlet 370 and the second glue inlet 380 can also be located on the same surface of the first template 300, as long as the first glue inlet 370 and the second glue inlet 380 do not interfere with each other during glue injection.

[0073] It should be noted that the cross-sectional area of ​​the first main channel 110 is larger than that of the first branch channel 120, and the cross-sectional area of ​​the second main channel 210 is larger than that of the second branch channel 220. Because the cross-sectional areas of the first main channel 110 and the second main channel 210 are relatively large, the flow rate of the adhesive in the first main channel 110 and the second main channel 210 can be relatively low, which is beneficial to improving the stability of molding and the quality of the finished product. Because the cross-sectional areas of the first branch channel 120 and the second branch channel 220 are relatively small, the ratio of adhesive flow can be controlled and adjusted to meet the requirements of different workpiece molding ratios. This reduces the amount of raw materials required during the molding process, thereby helping to reduce production costs and improve production efficiency.

[0074] In some embodiments, the injection channels between the first branch port 1221 and the first molding chamber 420, and between the second branch port 2221 and the second molding chamber 430, are arranged parallel to the moving direction of the first template 300 and the second template 400. This can effectively ensure the uniformity and smoothness of the material when it is injected into the first molding chamber 420 and the second molding chamber 430, which is beneficial to improving the product molding quality. The parallel injection channels can reduce the resistance of the material during the process of entering the first molding chamber 420 and the second molding chamber 430, reduce the possibility of material loss, save production costs, speed up the injection molding cycle, and thus improve production efficiency.

[0075] Another embodiment of the present invention, with reference to Figure 1 and Figure 5 As shown, a consistent injection mold for the production of automotive parts is provided, including a first mold plate 300, a second mold plate 400, and a hot runner system for the production of automotive parts according to any of the above embodiments, wherein the hot runner system is disposed on the first mold plate 300; the second mold plate 400 is adapted to move relative to the first mold plate 300 to a mold-closing state or a demolding state.

[0076] It is understood that since the hot runner system has the beneficial effects of the above embodiments, the injection mold also has the beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0077] According to an embodiment of the present invention, reference Figure 1 and Figure 5 As shown, the first template 300 is integrally formed and has a first flow channel structure 100 and / or a second flow channel structure 200.

[0078] Understandably, reference Figure 1 and Figure 6 In this embodiment, the first flow channel structure 100 or the second flow channel structure 200 is integrally formed in the first template 300, that is, the flow channel is integrally formed in the first template 300, serving as the first flow channel structure 100 for conveying the first injection molding material and the second flow channel structure 200 for conveying the second injection molding material.

[0079] In one specific embodiment, the first flow channel structure 100 is integrally formed on the first flow divider plate 330, and the second flow channel structure 200 is integrally formed on the second flow divider plate 340. The first flow divider plate 330 and the second flow divider plate 340 are arranged in a bridge-like manner, so that there is a gap between the first flow channel structure 100 and the second flow channel structure 200 to avoid heat transfer.

[0080] In one alternative implementation, refer to Figure 5 , Figure 7 , Figure 8 and Figure 9 The first mold plate 300 has multiple first mold core bodies 350, each with a molding surface 360. The second mold plate 400 has multiple second mold core bodies 410. The first mold core bodies 350 and the second mold core bodies 410 are movable relative to each other. The molding surface 360 ​​and the second mold core bodies 410 cooperate to mold automotive parts. This allows for the production of automotive parts made of two different materials on the same injection mold, namely, molding a first workpiece A (e.g., a caliper pin) and molding a second workpiece B (e.g., a caliper seat), which helps reduce production costs and space requirements.

[0081] Specifically, refer to Figure 9 , Figure 10 and Figure 11 The first mold core body 350 includes a first mold core unit 351 and a second mold core unit 352. The first mold core unit 351 and the second mold core unit 352 are arranged side by side and independently. The sides of the first mold core unit 351 and the second mold core unit 352 facing the second mold core body 410 cooperate to form a molding surface 360. The first mold core unit 351 and a part of the structure of the second mold core body 410 cooperate to form a first molding chamber 420 for molding the first workpiece A. The second mold core unit 352 and another part of the structure of the second mold core body 410 cooperate to form a second molding chamber 430 for molding the second workpiece B. The second mold core body 410 includes a fixed mold core component 411, a first movable mold core component 412, and a second movable mold core component 413. The fixed mold core component 411 is arranged facing the first mold core unit 351 to form and position the opposite sides of the outer periphery of the first workpiece A. The first movable mold core component 412 and the second movable mold core component 413 are arranged facing each other to form and position the other opposite sides of the outer periphery of the first workpiece A and the opposite ends of the first workpiece A along its length.

[0082] By setting multiple components facing each other, the first workpiece A can be better fixed and positioned, ensuring stability and accuracy during the molding process, which is beneficial to improving the molding quality of the product. Since the relative setting of each component can more accurately position the first workpiece A, the debugging time and the time for adjusting molding parameters can be reduced, thereby improving production efficiency. Through multi-directional positioning settings, the consistency and stability of the first workpiece A during the molding process can be ensured, avoiding product quality problems caused by inaccurate positioning.

[0083] Furthermore, through the above structure, the first mold core unit 351, the second mold core unit 352, the fixed mold core component 411, the first movable mold core component 412, and the second movable mold core component 413 can be manufactured and processed separately, providing flexibility in the manufacturing process. Separate and independent manufacturing allows for the selection of different processing techniques and materials according to actual needs, ensuring that each component meets the required precision, strength, and surface quality requirements. Multiple components can be processed and produced simultaneously, thereby shortening the entire manufacturing cycle and improving production efficiency. In addition, the design of the first movable mold core component 412 and the second movable mold core component 413 can be adjusted along different directions, facilitating mold closing and demolding. They can also slide along the first and second directions respectively, adjusting their position relative to the fixed mold core component 411, thereby adapting to the production of workpieces of different shapes and specifications.

[0084] Specifically, in some embodiments, the first template 300 is detachably provided with a first mold core unit 351 and a second mold core unit 352, and the second template 400 is detachably provided with a fixed mold core component 411, a first movable mold core component 412, and a second movable mold core component 413. Since the first mold core unit 351, the second mold core unit 352, the fixed mold core component 411, the first movable mold core component 412, and the second movable mold core component 413 are manufactured independently, component replacement and maintenance are easier. For example, when a first mold core unit 351 is damaged, only that component needs to be replaced without replacing the entire mold, reducing maintenance costs and downtime. Independently manufactured mold components can be individually inspected and adjusted to ensure that the precision and quality of each component meet requirements. Furthermore, if adjustments or improvements to the mold are needed, specific components can be modified or replaced more easily.

[0085] Furthermore, the first mold core unit 351, the second mold core unit 352, the fixed mold core component 411, the first movable mold core component 412, and the second movable mold core component 413 are all equipped with independent cooling water channels 500. The flow rate and temperature of the cooling water channel 500 for each component can be adjusted independently, thereby achieving more precise temperature control, improving the stability of temperature control, and thus improving product accuracy, cooling effect, and shortening the molding cycle. At the same time, this design can also avoid interference between different components, further improving temperature stability and accuracy stability.

[0086] In another embodiment of the present invention, a production equipment for the production of automotive parts is provided, including a hot runner system for the production of automotive parts according to any of the above embodiments or an injection mold for the production of automotive parts according to any of the above embodiments.

[0087] It is understood that since the hot runner system and injection mold have the beneficial effects of the above embodiments, the production equipment also has the beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
