Description

Technical Field

[0001] The invention relates to the technical field of injection molding cooling, and in particular to a bionic branch water channel, a plate body with the bionic branch water channel, and a manufacturing method. Background Art

[0002] In existing cooling systems, a design including a main water channel and multiple branch water channels is usually adopted. These branch water channels are connected to the main water channel respectively, and are used to transport the cooling medium to various areas that need cooling. However, in traditional designs, the diameter of the main water channel remains unchanged along its extension direction. Due to the effect of flow resistance, the farther the main water channel is from the main water inlet, the lower the water pressure and the slower the flow rate of the cooling water, resulting in uneven water pressure and flow rate of the cooling water flowing into each branch water channel, which ultimately makes the cooling effect of each component of the same set of molds inconsistent, thereby affecting the quality of the product and causing product quality differences.

[0003] The main problem of existing cooling water channel design is that it fails to effectively solve the pressure loss and flow distribution problems of cooling water in the main water channel. Specifically, it is manifested as follows: 1. Inefficient cooling: Due to uneven water pressure and flow rate, some locations may not receive adequate cooling, while other locations may be overcooled.

[0004] 2. Unstable product quality: Differences in cooling effects at different locations directly affect the quality of the final product, which may lead to problems such as reduced dimensional accuracy or surface defects.

[0005] 3. High energy consumption: In order to ensure sufficient cooling effect, it is often necessary to increase the pumping power, which increases energy consumption. Summary of the invention

[0007] Another object of the present invention is to provide a method for manufacturing a plate body with a bionic branch waterway, wherein the method manufactures the plate body by an additive manufacturing method.

[0008] The purpose of the present invention can be achieved through the following technical solutions: A bionic branch waterway comprises a main waterway and a plurality of branch waterways, wherein the main waterway comprises a main water inlet and a plurality of continuously connected main waterway segments, wherein the main waterway segments are sequentially connected along an axial direction, and the diameters decrease gradually in a direction away from the main water inlet; and each main waterway segment is connected to a corresponding branch waterway.

[0012] Preferably, the first branch waterway comprises a plurality of bionic branch waterways, and at least one of the first branch waterway and the second branch waterway comprises two bionic branch waterways directly connected to the main water outlet.

[0013] As a preference, the first branch waterway comprises at least three bionic branch waterways, and main water inlets of the bionic branch waterways included in the first branch waterway and the second branch waterway are alternately connected.

[0015] Preferably, the plate body further comprises a plate body component provided with a cooling channel, and the bionic branch water channels in the first branch water channel and the second branch water channel correspond to each other and are respectively connected to two ends of the corresponding cooling channel.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0026] It should be noted that, in the description of the present invention, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed", "connected", "connected", and "hollow" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Embodiment 1 like Figure 1As shown, this embodiment provides a bionic branch water channel. The bionic branch water channel 1 is arranged in the plate body 2. Its design inspiration comes from the vascular network in the body of a living being, and aims to achieve an efficient and uniform cooling effect.

[0029] The bionic branch water channel 1 includes a main water channel 11, four branch water channels 12 and a connecting port 13. The main water channel 11 includes a main water inlet 111 and four continuously connected main water channel segments 112. The four main water channel segments 112 are sequentially connected along the axial direction, and the diameters decrease gradually from the main water inlet 111 to the direction away from the main water inlet 111; each main water channel segment 112 is connected to a corresponding branch water channel 12, and the connecting port 13 is connected to the main water inlet 111. The diameter of the main water channel segment 112 is the largest near the main water inlet 111, and gradually decreases as it moves away from the main water inlet 111. This design ensures the reasonable distribution of fluid flow and avoids the problem of uneven flow in traditional fixed diameter water channels.

[0030] All the main waterway sections 112 are coaxially connected, ensuring that the fluid can flow along a straight path in the entire waterway system, reducing local resistance caused by bends and turns.

[0031] The cross-sectional area of ​​each branch waterway 12 is the same, and the cross-sectional area of ​​each main waterway segment 112 is equal to the sum of the cross-sectional areas of all branch waterways 12 downstream thereof. That is, the cross-sectional area of ​​the first branch waterway 12 is equal to the sum of the cross-sectional areas of the second branch waterway 12, the third branch waterway 12, and the fourth branch waterway 12. Starting from the main water inlet 111, in the direction away from the main water inlet 111, the cross-sectional area of ​​the first main waterway segment 112 is equal to the sum of the cross-sectional areas of the first branch waterway 12, the second branch waterway 12, the third branch waterway 12, and the fourth branch waterway 12 arranged along the decreasing direction of the diameter of the main waterway 11; the second main waterway segment 112, the third main waterway segment 112, and the fourth main waterway segment 112 are arranged in the same manner. Through the above method, the reasonable distribution of flow from the main waterway 11 to the branch waterway 12 is ensured, the situation where some branch waterways 12 are overloaded while other parts have insufficient flow is avoided, and the uniform distribution of fluid among the branch waterways 12 is achieved; the cross-sectional area of ​​each branch waterway 12 is kept constant, so that the fluid flow in each branch waterway 12 remains stable, which not only helps to maintain the pressure balance of the entire system, but also ensures that the flow rate in each branch waterway 12 is consistent.

[0032] In order to improve the smoothness of fluid flow, the branch waterway 12 is connected to the main waterway segment 112 through an arc transition structure, which can reduce flow resistance and improve transmission efficiency compared to right-angle connection.

[0033] The main water channel segment 112 of this embodiment further includes a segment body 1121 and a segment transition 1122 which are coaxially connected. The segment body 1121 and the segment transition 1122 are connected in sequence. The branch water channel 12 is connected to the segment transition 1122. The cross-sectional area of ​​the segment body 1121 is equal to the sum of the cross-sectional areas of all branch water channels 12 arranged along the decreasing direction of the diameter of the main water channel 11. The cross-sectional area of ​​the segment transition 1122 gradually decreases along the decreasing direction of the diameter of the main water channel 11 between the two segment bodies 1121 before and after it.

[0034] When the main water inlet 111 is used as an inlet, the cross-sectional area of ​​the segmented body 1121 decreases step by step until it is the same as the cross-sectional area of ​​the branch waterway 12; when the main water inlet 111 is used as an outlet, the cross-sectional area of ​​the segmented body 1121 increases gradually until it is the same as the cross-sectional area of ​​the main water inlet 111. The cross-sectional area of ​​the segmented body 1121 of this embodiment changes in an orderly manner, the purpose of which is to balance the distribution of cooling water between the branch waterway 12 corresponding to the segmented body 1121 and its downstream segmented body 1121, so that the flow rate and pressure distribution of cooling water in the branch waterways 12 at different positions in the flow direction are more uniform.

[0035] In this embodiment, the number of branch waterways 12 is four. During implementation, the number of branch waterways 12 is preferably two to eight, more preferably three to five, and the number of main waterway segments 112 is correspondingly the same as the number of branch waterways 12.

[0036] Embodiment 2 like Figure 2 As shown, this embodiment provides a plate body with a bionic branch waterway, wherein a row of bionic branch waterways is provided in the plate body 2, and the bionic branch waterway includes a first branch waterway 3 and a second branch waterway 4, and the first branch waterway 3 and the second branch waterway 4 include the same number of bionic branch waterways 1.

[0037] The first branch waterway 3 and the second branch waterway 4 respectively include a plurality of first branch waterway bionic branch waterways 31 and a second branch waterway bionic branch waterway 41 arranged in sequence along the length direction of the plate body 2. The first branch waterway bionic branch waterway 31 and the second branch waterway bionic branch waterway 41 are connected to the plate body 2. Figure 1 The embodiment shown in is the same.

[0038] In the first branch waterway 3, the two first branch waterway bionic branch waterways 31 are shown to be spaced apart and symmetrical about the vertical bisector between the two, and the vertical bisector is located between the two first branch waterway bionic branch waterways 31. In the second branch waterway 4, the two second branch waterway bionic branch waterways 41 are shown to be connected, that is, the main water inlets 411 of the two second branch waterway bionic branch waterways 41 are directly connected; the two second branch waterway bionic branch waterways 41 are symmetrical about the vertical bisector between the two, and the vertical bisector is located at the place where the main water inlets 411 of the two second branch waterway bionic branch waterways are connected. This symmetrical design in this embodiment helps to maintain the stability of fluid flow, optimize the flow path, and ensure that each position can obtain a consistent cooling effect.

[0039] The first branch waterway 3 and the second branch waterway 4 each include three or more bionic branch waterways ( Figure 2 The first branch waterway bionic branch waterway 31 includes a main water inlet 311 of the first branch waterway bionic branch waterway, a branch waterway 312 of the first branch waterway bionic branch waterway, and a connecting port 313 of the first branch waterway bionic branch waterway; the second branch waterway bionic branch waterway 41 includes a main water inlet 411 of the second branch waterway bionic branch waterway and a branch waterway 412 of the second branch waterway bionic branch waterway. In the direction away from the connecting port 313 of the first branch waterway bionic branch waterway, the two second branch waterway bionic branch waterways 41 of the second branch waterway 4 are connected through the main water inlet 411 of the second branch waterway bionic branch waterway, and then the two first branch waterway bionic branch waterways 31 of the first branch waterway 3 are connected through the main water inlet 311 of the first branch waterway bionic branch waterway. The second branch waterway 4 of the row of bionic branch waterways and the main water inlet of the first branch waterway 3 are alternately connected until the main water inlet of the first branch waterway bionic branch waterway 31 or the second branch waterway bionic branch waterway 41 is connected to the connecting port. The main water inlet 311 of the first branch waterway bionic branch waterway and the main water inlet 411 of the second branch waterway bionic branch waterway are staggered, so that the cooling water can be more evenly distributed to each position, ensuring that the cooling water can be evenly distributed throughout the plate body 2, avoiding the problem of local overheating or insufficient cooling. Among them, the connecting port 313 of the first branch waterway bionic branch waterway and the connecting port 313 of another first branch waterway bionic branch waterway are selected as the water inlet and outlet of the row of bionic branch waterways. This flexibility can adjust the cooling path according to actual needs to achieve the best cooling effect. In other embodiments, the main water inlets 311 of the two first branch waterway bionic branch waterways of the first branch waterway 3 can also be connected first. This arrangement helps the cooling water to flow alternately and maintain the stability and uniformity of the cooling water flow.

[0040] The first branch waterway 3 and the second branch waterway 4 respectively include the first branch waterway bionic branch waterway 31 and the second branch waterway bionic branch waterway 41, which correspond to each other. At the same time, the first branch waterway bionic branch waterway 31 and the second branch waterway bionic branch waterway 41 respectively include the first branch waterway bionic branch waterway 312 and the second branch waterway bionic branch waterway 412, which correspond to each other. The cooling water flows in the corresponding first branch waterway bionic branch waterway 312 and the second branch waterway bionic branch waterway 412. This corresponding design ensures the consistency of the cooling process, thereby improving the quality and consistency of the product.

[0041] The parts not mentioned in this embodiment are the same as those in the first embodiment.

[0042] Embodiment 3 like Figure 3 As shown, the present embodiment provides a schematic diagram of the water channel distribution of a plate body with a bionic branch waterway, in which the cross-sectional diameter of the plate body 2 and the cooling water flow path are not shown. The plate body 2 is provided with three rows of bionic branch waterways a, and each row of bionic branch waterways includes a first branch waterway 3 and a second branch waterway 4. This layout of multiple rows of bionic branch waterways a ensures that the cooling water can cover a larger cooling area to improve the cooling efficiency. The first branch waterway 3 includes three first branch waterway bionic branch waterways 31, each of which is provided with a main water inlet 311 of the first branch waterway bionic branch waterway and three branch waterways 312 of the first branch waterway bionic branch waterways. Correspondingly, the second branch waterway 4 includes three second branch waterway bionic branch waterways 41, each of which is provided with a main water inlet 411 of the second branch waterway bionic branch waterway and three branch waterways 412 of the second branch waterway bionic branch waterways.

[0043] The plate component 5 is provided with a cooling channel, and the branch channel 312 of the first branch water channel bionic branch water channel and the branch channel 412 of the second branch water channel bionic branch water channel are respectively connected to both ends of the cooling channel to form cooling for the plate component 5.

[0044] Each bionic branch water channel (the first branch water channel bionic branch water channel 31 or the second branch water channel bionic branch water channel 41) is provided with a main water inlet (the main water inlet 311 of the first branch water channel bionic branch water channel or the main water inlet 411 of the second branch water channel bionic branch water channel) and three branch water channels (the branch water channel 312 of the first branch water channel bionic branch water channel or the branch water channel 412 of the second branch water channel bionic branch water channel), and these branch water channels are respectively connected to the two ends of the cooling channel to form effective cooling for the plate body component 5. The dense branch water channel design enables the cooling water to be quickly and evenly distributed to each position that needs cooling, further enhancing the uniformity of cooling.

[0045] The water inlet channel 6 and the water outlet channel 7 are respectively located at the two ends of the multi-row bionic branch waterway a. The water inlet channel 6 includes a water inlet channel bionic branch waterway 61, which is provided with a main water inlet 611 of the water inlet channel bionic branch waterway and three branch waterways 612 of the water inlet channel bionic branch waterway; correspondingly, the water outlet channel 7 includes a water outlet channel bionic branch waterway 71, which is provided with a main water inlet 711 of the water outlet channel bionic branch waterway and three branch waterways 712 of the water outlet channel bionic branch waterway; the main water inlet 611 of the water inlet channel bionic branch waterway and the main water inlet 711 of the water outlet channel bionic branch waterway serve as the inlet and outlet ends of the cooling water respectively. This design not only ensures that the fluid path is clear and definite, but also reduces local resistance and improves the stability of fluid flow.

[0046] The main water inlet 411 of a second branch waterway bionic branch waterway of the second branch waterway 4 serves as a water inlet, which is connected to a branch waterway 612 of the bionic branch waterway of the water inlet channel; the main water inlet 311 of a first branch waterway bionic branch waterway of the first branch waterway 3 serves as a water outlet, which is connected to a branch waterway 712 of the bionic branch waterway of the water outlet channel.

[0047] In this embodiment, the water inlet channel 6 and the water outlet channel 7 are preferred solutions, and bionic branch waterways are used as paths connecting each row of bionic branch waterways a; in other embodiments, the water inlet channel 6 and the water outlet channel 7 use ordinary equal-diameter channels.

[0048] As a further implementation scheme, the water inlet channel 6 and the water outlet channel 7 respectively have multiple bionic branch waterways 1. At this time, the structure and effect of the water inlet channel 6 and the water outlet channel 7 are similar to the bionic branch waterway formed by the first branch waterway 3 and the second branch waterway 4. The only difference is that the objects connected to the branch waterways are different.

[0049] This configuration ensures a clear and defined fluid path, further improving cooling efficiency and uniformity.

[0050] In practice, the plate body with bionic branch water channels can be applied to an injection mold, which includes a movable half mold, the movable half mold is provided with a core plate and a slide plate, the core plate is installed with a plurality of core structures, the slide plate is installed with a die lip corresponding to the core structure, the core structure and the die lip are both provided with cooling channels, and at least one of the core plate and the slide plate is any of the above-mentioned plate bodies with bionic branch water channels. The branch water channel of the first branch water channel is connected to the water inlet or water outlet of the cooling channel of the core structure and / or the die lip, and the branch water channel of the second branch water channel corresponds to the water outlet or water inlet of the cooling channel connected to the core structure and / or the die lip.

[0051] The injection mold significantly improves the cooling efficiency and uniformity by introducing a plate body with bionic branch water channels, especially in the core plate and the slide plate.

[0052] The parts not mentioned in this embodiment are the same as those in Embodiment 1 and Embodiment 2.

[0053] Embodiment 4 This embodiment provides a method for manufacturing a plate body with a bionic branch water channel, and adopts an additive manufacturing method to manufacture the plate body with a bionic branch water channel.

[0054] The plate 2 is manufactured using additive manufacturing (i.e., 3D printing) technology, which avoids the process complexity and possible process defects caused by subtractive processing, such as process holes, multi-part assembly, etc., and ensures the quality and consistency of the plate 2. Additive manufacturing allows rapid prototyping and customized production to meet different application requirements, while reducing manufacturing costs and time.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
