[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] Figure 1 This is a flow chart of a method for generating injection time parameters according to an embodiment of the present application.

[0065] like Figure 1 As shown, the method for generating injection time parameters provided in this embodiment is applied to an electronic device, and is used to generate injection time parameters expressed by curve driving, so that the injection molding equipment can produce qualified injection molded products based on the injection time parameters. The electronic device here can be understood as a computer, server or cloud platform with data computing and information processing capabilities. The generation method of this application includes the following steps:

[0066] S1. Obtain the model information and configuration file of the injection molding product.

[0067] Injection molded products refer to products to be molded, such as parts, boxes, or toys. The model information refers to the three-dimensional geometric information of the model, which is usually represented by CAD or some triangular patch format files, such as STL file format. In this application, STL is used to represent the three-dimensional geometric information of the part. When acquiring, the model information is imported in the form of an STL file. Figure 2 This is a circular gasket model. This article uses this model as an example to illustrate the calculation process and analyze the calculation results. In addition, after reading in the model information, it is necessary to conduct a preliminary check on the model to see if the model is complete. The configuration information includes voxel grid size, part injection position, material properties, injection screw speed curve, injection screw diameter, and mold temperature.

[0068] S2. Divide the part body mesh of the injection molded product to obtain multiple voxel meshes.

[0069] That is, the part body is meshed according to the model information of the injection molded product to obtain multiple voxel grids. For example, according to the STL model of the part, the part is divided into voxel grids by the threading method. First, the minimum wall thickness T of the part and the diagonal length L of the bounding box are estimated, and the grid size Δx = min(T / 2,L). The STL file consists of a series of triangular patches, and the closed space formed by the triangular patches is the geometry of the part. In order to reduce the space of the model file, the size of the triangular patches in the STL file is very uneven. The threading method is used to generate a series of light clusters, find the intersection between the light and the triangular patches in the STL, and generate a cubic mesh between the intersection points, as shown below. Figure 3 shown.

[0070] S3. Capture each voxel grid according to the configuration file.

[0071] By capturing all voxel grids, they are processed into multiple captured grids. The specific process is as follows:

[0072] First, the position information of the injection gate of the configuration file is searched from multiple voxel grids, and the voxel grid closest to the injection gate is determined as the first captured grid.

[0073] Then, all voxel grids are traversed according to the first captured grid to obtain all captured grids. Voxel grids are divided into two categories: captured grids and uncaptured grids. The grids above, below, left, right, front, and back of a grid become the neighbor grids of this grid. If there are uncaptured grids in the neighbor grids of the captured grid, it is called a boundary grid. By traversing all boundary grids, each boundary grid is allowed to capture the uncaptured grids around it, and the uncaptured grids are set as captured grids. After completing the capture of all boundary grids, the grids captured by the capture process are saved, recorded in the array N, and the boundary grids are updated.

[0074] Starting from the initialization condition, the capture process is executed cyclically until all voxel grids are captured grids. N is called a capture unit array, and each element Ni represents the grid captured at each step. This array can well reflect the sequence of the injection molding filling process and the number of capture units at each step. The more units, the larger the area of ​​the interface front. The specific process is as follows Figure 4 shown.

[0075] S4. Calculate the area of ​​the interface front at each moment based on the captured grid.

[0076] On the basis of capturing a plurality of captured grids, all captured grids are calculated to obtain the area of ​​the interface front of the injection molded product at each moment during injection molding.

[0077] Specifically, during the calculation, the following formula is used to calculate and obtain multiple areas A i :

[0078] A i =N i Δx 2

[0079] Among them, N i is the i-th captured grid, and Δx is the grid size of the i-th captured grid.

[0080] S5. Calculate based on all areas to obtain injection time parameters.

[0081] During the injection molding process, maintaining a stable flow velocity at the front of the filling interface is the key to improving the quality of the injection molded product. Under the condition of maintaining a consistent velocity at the front of the filling interface, the faster the injection speed, the better. Therefore, the injection speed curve can be calculated as follows:

[0082] First, the maximum area Amax and the maximum injection speed Vmax of the injection molding machine are calculated based on the following formula to obtain the injection speed V of a specific interface: c :

[0083]

[0084] Where D is the radius of the specific interface;

[0085] Then, based on the injection velocity at each specific interface, the injection velocity V used at the leading edge of each specific interface is obtained. i :

[0086]

[0087] Among them, A i is the i-th voxel grid;

[0088] Then, the total injection speed is converted into stroke percentage Ri based on the following formula:

[0089]

[0090] Wherein, sum(Vi) is the sum of all the injection speeds;

[0091] The injection time parameters expressed as the injection time curve are plotted based on the stroke percentage.

[0092] It can be seen from the above technical solution that this embodiment provides a method for generating injection time parameters, which is applied to electronic devices, specifically obtaining model information and configuration files of injection molded products; meshing the injection molded products according to the model information to obtain multiple voxel grids; capturing each voxel grid according to the configuration file to obtain multiple captured grids; calculating the area of ​​the interface front of the injection molded product at each moment during injection based on the multiple captured grids; and calculating based on all areas to obtain the injection time parameters of the injection molded product. This solution can obtain the injection time parameters based on the input model information and configuration files, without the need for engineers to manually set the speed parameters and make corrections through repeated trial molds and actual injection molding, thereby not only saving time, but also avoiding waste of materials.

[0097] Figure 5 This is a block diagram of a device for generating injection time parameters according to an embodiment of the present application.

[0098] like Figure 5 As shown, the injection time parameter generation device provided in this embodiment is applied to an electronic device, and is used to generate injection time parameters expressed by curve driving, so that the injection molding equipment can produce qualified injection molded products based on the injection time parameters. The electronic device here can be understood as a computer, server or cloud platform with data computing and information processing capabilities. The generation device of the present application includes an information acquisition module 10, a grid division module 20, a grid capture module 30, an area calculation module 40 and a parameter output module 50.

[0099] The information acquisition module is used to obtain the model information and configuration files of the injection molding product.

[0100] Injection molded products refer to products to be molded, such as parts, boxes, or toys. The model information refers to the three-dimensional geometric information of the model, which is usually represented by CAD or some triangular patch format files, such as STL file format. In this application, STL is used to represent the three-dimensional geometric information of the part. When acquiring, the model information is imported in the form of an STL file. Figure 2 This is a circular gasket model. This article uses this model as an example to illustrate the calculation process and analyze the calculation results. In addition, after reading in the model information, it is necessary to conduct a preliminary check on the model to see if the model is complete. The configuration information includes voxel grid size, part injection position, material properties, injection screw speed curve, injection screw diameter, and mold temperature.

[0101] The meshing module is used to mesh the parts of injection molded products to obtain multiple voxel grids.

[0102] That is, the part body is meshed according to the model information of the injection molded product to obtain multiple voxel grids. For example, according to the STL model of the part, the part is divided into voxel grids by the threading method. First, the minimum wall thickness T of the part and the diagonal length L of the bounding box are estimated, and the grid size Δx = min(T / 2,L). The STL file consists of a series of triangular patches, and the closed space formed by the triangular patches is the geometry of the part. In order to reduce the space of the model file, the size of the triangular patches in the STL file is very uneven. The threading method is used to generate a series of light clusters, find the intersection between the light and the triangular patches in the STL, and generate a cubic mesh between the intersection points, as shown below. Figure 3 shown.

[0103] The grid capture module is used to capture each voxel grid according to the configuration file.

[0104] By capturing all voxel grids, they are processed into multiple captured grids. The specific process is as follows:

[0105] First, the position information of the injection gate of the configuration file is searched from multiple voxel grids, and the voxel grid closest to the injection gate is determined as the first captured grid.

[0106] Then, all voxel grids are traversed according to the first captured grid to obtain all captured grids. Voxel grids are divided into two categories: captured grids and uncaptured grids. The grids above, below, left, right, front, and back of a grid become the neighbor grids of this grid. If there are uncaptured grids in the neighbor grids of the captured grid, it is called a boundary grid. By traversing all boundary grids, each boundary grid is allowed to capture the uncaptured grids around it, and the uncaptured grids are set as captured grids. After completing the capture of all boundary grids, the grids captured by the capture process are saved, recorded in the array N, and the boundary grids are updated.

[0107] Starting from the initialization condition, the capture process is executed cyclically until all voxel grids are captured grids. N is called a capture unit array, and each element Ni represents the grid captured at each step. This array can well reflect the sequence of the injection molding filling process and the number of capture units at each step. The more units, the larger the area of ​​the interface front. The specific process is as follows Figure 4 shown.

[0108] The area calculation module is used to calculate the area of ​​the interface front at each moment based on the captured grid.

[0109] On the basis of capturing a plurality of captured grids, all captured grids are calculated to obtain the area of ​​the interface front of the injection molded product at each moment during injection molding.

[0110] Specifically, during the calculation, the following formula is used to calculate and obtain multiple areas A i :

[0111] A i =N i Δx 2

[0112] Among them, N i is the i-th captured grid, and Δx is the grid size of the i-th captured grid.

[0113] The parameter output module is used to calculate according to all areas and obtain the injection time parameters.

[0114] During the injection molding process, maintaining a stable flow velocity at the front of the filling interface is the key to improving the quality of the injection molded product. Under the condition of maintaining a consistent velocity at the front of the filling interface, the faster the injection speed, the better. Therefore, the injection speed curve can be calculated as follows:

[0115] First, the maximum area Amax and the maximum injection speed Vmax of the injection molding machine are calculated based on the following formula to obtain the injection speed V of a specific interface: c :

[0116]

[0117] Where D is the radius of the specific interface;

[0118] Then, based on the injection velocity at each specific interface, the injection velocity V used at the leading edge of each specific interface is obtained. i :

[0119]

[0120] Among them, A i is the i-th voxel grid;

[0121] Then, the total injection speed is converted into stroke percentage Ri based on the following formula:

[0122]

[0123] Wherein, sum(Vi) is the sum of all the injection speeds;

[0124] The injection time parameters expressed as the injection time curve are plotted based on the stroke percentage.

[0125] It can be seen from the above technical scheme that this embodiment provides a device for generating injection time parameters, which is applied to electronic devices, specifically to obtain model information and configuration files of injection molded products; divide the part body of the injection molded product into meshes according to the model information to obtain multiple voxel grids; capture and process each voxel grid according to the configuration file to obtain multiple captured grids; calculate the area of ​​the interface front of the injection molded product at each moment during injection molding based on the multiple captured grids; calculate based on all areas to obtain the injection time parameters of the injection molded product. This solution can obtain the injection time parameters based on the input model information and configuration files, without the need for engineers to manually set the speed parameters and make corrections through repeated trial molds and actual injection molding, thereby not only saving time, but also avoiding waste of materials.
