[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example Please see Figures 1 to 10 A method for designing water channels in an injection mold, applied to injection molds; the method for designing water channels in an injection mold includes: Step S11: Traverse the injection mold and locate the core part and the interference part; Step S12: Construct the waterway influence area based on the region where the core part is located and the region where the interference part is located; Step S13: Define the water inlet of the water channel based on the area affected by the water channel and the material flow direction in the mold core; Step S14: Determine multiple paths of the water channel based on the outer contour of the injection molded part formed by the inlet and the core part; Step S15: Collect the heat distribution area of ​​the injection mold and divide it into multiple sub-heat areas based on the heat distribution area; Step S16: Define the optimal water path based on multiple sub-heat zones and multiple water paths; Step S17: Gradually form the water channels of the injection mold along the optimal water channel path.

[0019] In this embodiment of the invention, the method introduces the core portion and interference portion of the injection mold, and constructs a water channel influence area based on the area where the core portion and interference portion are located. This facilitates the control of the inlet and multiple paths of the water channel within the water channel influence area. Simultaneously, the optimal water channel path is defined based on multiple sub-heat areas and multiple water channel paths, so that the water channel of the injection mold is gradually formed along the optimal water channel path. This ensures that the water channel design of the injection mold is compatible with the consideration of the water channel influence area and multiple sub-heat areas, improves the design accuracy of the injection mold water channel, ensures the arrangement of the injection mold water channel, and enhances the overall control effect of the injection mold.

[0020] In step S11, the injection mold is traversed, and the core portion and the interference portion are located; In the specific implementation of this invention, the specific steps can be as follows: S111: Collect the injection mold number; S112: Matching the virtual model of the injection mold based on the number of the injection mold; S113: Perform a full traversal of the virtual model of the injection mold and mark each part of the injection mold in sequence; S114: Position the core part of the injection mold and construct the interference center with the core part as the center; S115: Traverse outwards from the interference center to locate the interference part associated with the core part; S116: Construct the interference set of the waterway based on the core part and the interference part.

[0021] In the embodiments of this application, the number of the injection mold is collected, and the corresponding model file is selected based on the number of the injection mold, so as to match the virtual model of the injection mold according to the model file, thereby introducing the virtual model of the injection mold, so as to perform a comprehensive traversal according to the virtual model of the injection mold, and mark each part of the injection mold in sequence, thus ensuring the accuracy of each part in the injection mold.

[0022] At this point, the core part of the injection mold is located, and an interference center is constructed with the core part as the center. The interference center is then used to establish outward correlation, and the process is repeated outward from the interference center to locate the interference parts associated with the core part. Based on the core part and the interference parts, an interference set of water channels is constructed. Therefore, the interference set of water channels is a multi-layered layout with the core part as the center and the interference parts as the periphery. The core idea of ​​the core part is determined so that the water channels of the injection mold can be designed in multiple ways based on the core part and the interference parts.

[0023] In step S12, the waterway influence area is constructed based on the area where the core part is located and the area where the interference part is located; In the specific implementation of this invention, the specific steps can be as follows: S121: Location of the core sample; S122: Define the area where the mold core is located based on its position. S123: Locate multiple corners in the area where the core part is located, and trigger optimization of the area where the core part is located based on the misalignment distance between the multiple corners; S124: Location of the interference section; S125: Define the region where the interference part is located based on its position; S126: Correlate the region where the interference part is located with the region where the mold core is located, and calculate the distance difference between the region where the interference part is located and the region where the mold core is located; S127: Based on the distance difference, the area where the interference part is located is connected to the area where the mold core part is located, and a waterway prohibition area is formed. This waterway prohibition area connects the area where the interference part is located and the area where the mold core part is located, and prohibits the opening of waterways. S128: Construct the waterway influence area based on the area where the core part is located, the waterway prohibited area, and the area where the interference part is located.

[0024] In the embodiments of this application, the location of the mold core is collected and positioned, thereby defining the area where the mold core is located, and then fixing the mold core area. In the mold core area, multiple corners of the area where the mold core is located are located, and the optimization of the area where the mold core is located is triggered according to the misalignment distance between the multiple corners, thereby achieving further optimization of the mold core area, and aligning processing is performed on the multiple corners.

[0025] Simultaneously, the location of the interference part is collected to define the region where the interference part is located, thus introducing the interference region. In the interference region, the region where the interference part is located is associated with the region where the mold core is located, and the distance difference between the region where the interference part is located and the region where the mold core is located is calculated.

[0026] At this point, the distance difference triggers the connection between the area where the interference part is located and the area where the mold core is located, forming a waterway prohibition zone. This waterway prohibition zone connects the area where the interference part is located and the area where the mold core is located, and prohibits the opening of waterways, thus ensuring the control of the area between the area where the interference part is located and the area where the mold core is located, and controlling the distance difference between the area where the interference part is located and the area where the mold core is located. Therefore, the waterway influence zone is constructed based on the area where the mold core is located, the waterway prohibition zone, and the area where the interference part is located. The waterway avoidance design is controlled through the waterway influence zone, ensuring the design safety of the waterway.

[0027] In step S13, the water inlet of the water channel is defined according to the area affected by the water channel and the material flow direction in the mold core. In the specific implementation of this invention, the specific steps can be as follows: S131: Obtain the area affected by the waterway; S132: Divide the waterway influence area into multiple sub-regions; S133: Weight of waterway influence corresponding to the affected sub-region marker; S134: Based on the magnitude of the influence weight, multiple influence sub-regions are integrated sequentially to form a core influence region; S135: Define the water inlet of the water channel based on the core influence area and the material flow direction in the mold core.

[0028] In the embodiments of this application, the waterway influence area is obtained, and multiple influence sub-regions are divided based on the waterway influence area to facilitate the division of the waterway influence area, thereby enabling synchronous control of each influence sub-region. At this time, the waterway influence weight corresponding to the influence sub-region is assigned, and multiple influence sub-regions are integrated sequentially according to the magnitude of the influence weight to form a core influence area. The waterway inlet is defined based on the core influence area and the material flow direction in the mold core, ensuring the rationality of the waterway inlet. At the same time, the correlation between the core influence area and the material flow direction in the mold core is introduced to reflect the stability of the waterway inlet.

[0029] S14: Determine multiple paths of the water channel based on the outer contour of the injection molded part formed by the inlet and the core part; In the specific implementation of this invention, the specific steps can be as follows: S141: Collect the water inlet and mark its location and direction of water flow; S142: Define the starting point of the path based on the location of the inlet; S143: Collect the injection molded part formed by the mold core and define the outer contour of the injection molded part; S144: Defines the flow direction of the material along the outer contour of the injection molded part; S145: Define the molding sequence of each sub-component in the injection molded part according to the flow direction of the material flow; S146: Associating the molding sequence of each sub-component and the location of the water inlet; S147: Mark the sub-channels of the waterway in the order of molding of each sub-component; S148: Determine multiple paths of the waterway based on the sub-channels of the waterway and the starting point of the path.

[0030] In the embodiments of this application, the water inlet is collected and its location and water inlet direction are marked. The starting point of the path is defined based on the location of the water inlet, thereby controlling the subsequent waterway path based on the location of the water inlet.

[0031] Simultaneously, the injection molded parts formed by the mold core are collected, and the outer contour of the injection molded parts is defined. The outer contour of the injection molded parts is introduced and controlled. At this time, the flow direction of the material flow is defined along the outer contour of the injection molded parts; the molding sequence of each sub-component in the injection molded parts is defined according to the flow direction of the material flow.

[0032] Furthermore, the molding sequence of each sub-component and the location of the water inlet are associated; the sub-channels of the water path are marked sequentially according to the molding sequence of each sub-component; multiple paths of the water path are determined according to the sub-channels of the water path and the starting point of the path, so as to ensure the control of multiple paths of the water path, so as to introduce the association between the molding sequence of each sub-component and the location of the water inlet, thereby controlling the water path along the molding sequence of each sub-component.

[0033] S15: Collect the heat distribution area of ​​the injection mold and divide it into multiple sub-heat areas based on the heat distribution area; In the specific implementation of this invention, the specific steps can be as follows: S151: Collect injection molded parts based on the output of the injection mold; S152: Matching the molding area in the injection mold based on the outer contour of the injection molded part; S153: Mark the corresponding heat parameters for the molding area in the injection mold and form a heat distribution area; S154: Divide the heat distribution area to output multiple sub-heat areas.

[0034] In the embodiments of this application, the injection molded part output from the injection mold is collected and controlled to introduce the outer contour of the injection molded part. At this time, the molding area in the injection mold is matched based on the outer contour of the injection molded part, and the corresponding heat parameters are marked for the molding area in the injection mold to form a heat distribution area. In order to further control the heat distribution area, the heat distribution area is divided to output multiple sub-heat areas, and in-depth control is carried out based on multiple sub-heat areas.

[0035] S16: Define the optimal water path based on multiple sub-thermal zones and multiple water paths; In the specific implementation of this invention, the specific steps can be as follows: S161: Based on multiple sub-thermal regions, the corresponding thermal parameters are marked; S162: Mark the heat change amount for two adjacent sub-heat regions, and adjust the transition length between multiple sub-channels of the waterway according to the heat change amount; S163: Sequentially sort multiple sub-thermal regions along the direction of increasing thermal parameters; S164: Define the docking direction of multiple sub-channels sequentially based on the sorting direction of multiple sub-heat regions; S165: Match the length of the corresponding sub-channel according to the heat parameters of each sub-heat zone; S166: Collect the length of each sub-channel, the docking direction of multiple sub-channels, and the multiple paths of the waterway to define the optimal waterway path.

[0036] In the embodiments of this application, the heat parameters corresponding to multiple sub-heat regions are marked and controlled. At this time, the heat change amount is marked for two adjacent sub-heat regions, and the transition length between multiple sub-channels of the waterway is adjusted according to the heat change amount. This introduces the control of the transition length and manages the connection between two adjacent sub-channels.

[0037] Simultaneously, multiple sub-heat regions are sequentially sorted along the direction of increasing heat parameters, and the docking direction of multiple sub-channels is sequentially defined based on the sorting direction of the multiple sub-heat regions; thus, the length of the corresponding sub-channel is matched according to the heat parameters of each sub-heat region; the length of each sub-channel, the docking direction of multiple sub-channels, and multiple paths of the waterway are collected to define the optimal waterway path, ensuring the rationality of the optimal waterway path.

[0038] Therefore, the core and interference parts of the injection mold are introduced, and a water channel influence area is constructed based on the area where the core and interference parts are located. This facilitates the control of the inlet and multiple paths of the water channel within the influence area. At the same time, the optimal water channel path is defined based on multiple sub-heat areas and multiple water channel paths, so that the water channel of the injection mold can be gradually formed along the optimal water channel path. This ensures that the water channel design of the injection mold is compatible with the consideration of the water channel influence area and multiple sub-heat areas, improves the design accuracy of the water channel of the injection mold, ensures the layout of the water channel of the injection mold, and improves the overall control effect of the injection mold.

[0039] S17: Gradually form the water channel of the injection mold along the optimal water channel path; In the specific implementation of this invention, the specific steps can be as follows: S171: Optimal waterway route for data collection; S172: Define the length of each sub-channel sequentially along the optimal waterway path to form the waterway of the injection mold; S173: Associates the length of each sub-channel with the injection mold water channels; S174: Based on the water circuit of the injection mold, the water circuit is simulated, and the water flow of each sub-channel is triggered sequentially according to the temperature adjustment of multiple sub-heat zones; S175: Record the cooling coefficients of multiple sub-heat zones, and adjust the length of the corresponding sub-channels according to the cooling coefficients and molding parameters of the sub-heat zones to construct an optimized injection mold water channel.

[0040] In the embodiments of this application, the optimal waterway path is collected and controlled based on the optimal waterway path. At this time, the length of each sub-channel is defined sequentially along the optimal waterway path to facilitate the control of the length of each sub-channel.

[0041] Furthermore, the lengths of each sub-channel and the water channels of the injection mold are correlated; water channel simulation is performed based on the water channels of the injection mold, and the water flow of each sub-channel is triggered sequentially according to the temperature adjustment of multiple sub-heating regions; the cooling coefficients of multiple sub-heating regions are recorded, and the lengths of the corresponding sub-channels are adjusted according to the cooling coefficients and molding parameters of the sub-heating regions to construct an optimized water channel for the injection mold, realizing the autonomous optimization of the water channels of the injection mold and fully demonstrating the simulation of the water channels of the injection mold.

[0042] In this embodiment of the invention, the method introduces the core portion and interference portion of the injection mold, and constructs a water channel influence area based on the area where the core portion and interference portion are located. This facilitates the control of the inlet and multiple paths of the water channel within the water channel influence area. Simultaneously, the optimal water channel path is defined based on multiple sub-heat areas and multiple water channel paths, so that the water channel of the injection mold is gradually formed along the optimal water channel path. This ensures that the water channel design of the injection mold is compatible with the consideration of the water channel influence area and multiple sub-heat areas, improves the design accuracy of the injection mold water channel, ensures the arrangement of the injection mold water channel, and enhances the overall control effect of the injection mold.
