[0002] In the process of plastic product injection molding, a potential flow line is formed at the confluence area of the plastic filling flow. When the pressures of the confluence filling flows are inconsistent, that is, the pressure of the melt flow on one side of the confluence line is significantly greater than that on the other side, the melt flow on the high-pressure side will extrude to the low-pressure side, that is, the melt flow direction in this area will obviously deviate to one side of the confluence line, causing the confluence line in this area to extrude and deviate to the low-pressure side, and a raised mark is formed on the surface of the plastic product.

[0070] The following describes the flow line improvement method provided by the embodiments of the present application in combination with the flow line improvement system shown in the drawings. Figure 1 The flow line improvement method provided by the embodiments of the present application is described in combination with the flow line improvement system shown in the drawings.

[0071] Figure 3 A flow line improvement method is provided for the embodiments of the present application, which is applied to an improvement device and can also be applied to a controller in a flow line improvement system. The controller can be Figure 1 The flow line improvement device 11 in the flow line improvement system 10 can also be a device such as a chip in the flow line improvement device 11.

[0072] The embodiments of the present application are described by taking the flow line improvement device 11 as an example, as shown in the drawings, and the method includes the following S301-S304: Figure 3 The flow line improvement method provided by the embodiments of the present application is described in combination with the flow line improvement system shown in the drawings.

[0073] S301, the undercurrent line improvement device obtains a model file of a target object.

[0074] The target object can be an injection molding product. For example, it can be an automobile pillar interior panel. The model file of the target object can include modeling grid size, grid aspect ratio, etc.

[0075] For example, the grid size of a large injection molding product is 7mm-10mm, the grid size of a medium product is 4mm-6mm, and the grid size of a small product is 1mm-3mm. The grid aspect ratio of a large product is ≤10, and the grid aspect ratio of a medium and small product is ≤5. (For example, a large injection molding product can be 1000mm*500mm, and a medium injection molding product can be 500mm*500mm.)

[0076] As a possible implementation, the undercurrent line improvement device can obtain three-dimensional data of the target object; and use a preset modeling software to process the three-dimensional data to obtain the model file of the target object.

[0077] For example, the preset modeling software can be CADdoctor, HyperMesh, Moldex3D, etc.

[0078] S302, the undercurrent line improvement device uses a preset process analysis software to process the model file to obtain a molding evaluation result of the target object.

[0079] The preset process analysis software can be set as needed. For example, it can be MoldFlow, Moldex3D, etc. The molding evaluation result includes the filling flow direction of the target object and the position of the filling flow convergence line, and can also include the average velocity of the filling flow, etc. The material of the filling flow can be set as needed. For example, it can be plastic, synthetic metal, etc.

[0080] For example, the position of the convergence line can be as shown in Figure 4 .

[0081] As a possible implementation, the undercurrent line improvement device can input the model file into the preset process analysis software to obtain the molding evaluation result of the target object.

[0082] S303, the undercurrent line improvement device determines whether the target object has an undercurrent line according to the filling flow direction and the position of the filling flow convergence line.

[0083] As a possible implementation, the potential flow line improvement device can determine the confluence line position area of the filling flow, and determine whether the direction of the filling flow is obviously deviated, and in the case that the direction of the filling flow is obviously deviated, determine whether the target object has a potential flow line.

[0084] For example, as shown in Figure 5 , the potential flow line improvement device can determine that the direction of the filling flow is obviously deviated in the case that the angle difference between the filling flow direction and the confluence line position is greater than a first threshold. The first threshold can be set as needed, for example, it can be 10 degrees, or 15 degrees, etc. That is, the filling pressure of the left flow of the confluence line is obviously greater than that of the right flow, so that the confluence line is extruded and deviated to the right side, and the appearance surface of the area will appear the protruding potential flow line defect, and it is determined that the appearance surface of the area has the potential flow line defect.

[0085] For another example, as shown in Figure 6 , the potential flow line improvement device can determine that the direction of the filling flow is not obviously deviated in the case that the angle difference between the filling flow direction and the confluence line position is less than or equal to the first threshold. That is, the filling pressure of the left and right flows of the confluence line is basically the same, and the confluence line is not extruded and deviated, so that the appearance surface of the area will not appear the protruding potential flow line defect, and it is determined that the appearance surface of the area has no potential flow line defect.

[0086] For another example, in the case that the preset process analysis software is MoldFlow molding analysis software, the potential flow line improvement device can confirm the confluence line position of the appearance surface of the injection molded product through the output evaluation item Weld lines (confluence line or weld line, which can be used to evaluate the confluence line distribution position and quality of the injection molded product surface).

[0087] It should be noted that the specific description of whether the target object has a potential flow line according to the filling flow direction and the confluence line position of the filling flow in the possible implementation will be described in the subsequent part, and the present application will not be described here.

[0088] S304, the potential flow line improvement device adjusts the filling flow direction in the case that the target object has a potential flow line.

[0089] Among them, the angle difference between the adjusted filling flow direction and the confluence line position is less than the first threshold.

[0090] As a possible implementation, the potential flow line improvement device can adjust the filling flow direction by increasing the wall thickness of the target area.

[0091] It should be noted that the specific description of adjusting the filling flow direction in the possible implementation will be described in the subsequent part, and the present application will not be described here.

[0092] Based on the technical solutions provided in the present application, the preset process analysis software is used to process the model file to obtain the molding evaluation result of the target object; the filling flow direction of the target object and the position of the filling flow convergence line can be obtained. Further, according to the filling flow direction and the position of the filling flow convergence line, it is determined whether the target object has a potential flow line; in the case that the target object has a potential flow line, the filling flow direction is adjusted; the angle difference between the adjusted filling flow direction and the position of the filling flow convergence line is less than a first threshold value, so that the risk of surface potential flow line of the injection molded part can be predicted and optimized and improved. The surface potential flow line defect problem of the injection molded part after production is avoided, mold modification and design change are avoided, the appearance quality of the injection molded part is improved, and the product modification cycle and cost are saved.

[0093] As shown in FIG. 1, in order to determine whether the target object has a potential flow line, S303 in the improvement method of the present application can further include S401-S402. Figure 7

[0094] S401, the potential flow line improvement device determines a detection area.

[0095] The detection area is located on both sides of the position of the filling flow convergence line, and the distance from the position of the filling flow convergence line is less than a second threshold value. The second threshold value can be set as needed. For example, it can be 30 mm.

[0096] As a possible implementation, in the case that the convergence line is a straight line, after determining the position of the convergence line, the potential flow line improvement device can extend to both sides based on the convergence line, and determine the extended area as the detection area.

[0097] As another possible implementation, in the case that the convergence line is a curve, the potential flow line improvement device can correct the convergence line (for example, based on the midpoint of the convergence line, extend in a direction parallel to the target object), obtain the corrected position of the convergence line, and extend to both sides based on the corrected convergence line, and determine the extended area as the detection area.

[0098] S402, the potential flow line improvement device determines whether the target object has a potential flow line in the case that there is an abnormal filling flow direction in the detection area.

[0099] The angle difference between the abnormal filling flow direction and the position of the convergence line is greater than a first threshold value.

[0100] ​As a possible implementation manner, the underflow line improvement apparatus can divide the detection area into a plurality of sub-areas, determine the filling flow direction of each sub-area, further compare the filling flow direction of each sub-area with the abnormal filling flow direction, determine the angle difference between the filling flow direction of each sub-area and the position of the confluence line, and determine that the target object has the underflow line in a case where the angle difference between the filling flow direction of each sub-area and the position of the confluence line is greater than a first threshold value.

[0101] As another possible implementation manner, the underflow line improvement apparatus can divide the detection area into a plurality of sub-areas, determine the filling flow direction of each sub-area, further compare the filling flow direction of each sub-area with the abnormal filling flow direction, determine the angle difference between the filling flow direction of each sub-area and the position of the confluence line, and determine that the target object has the underflow line in a case where the angle difference between the filling flow direction of each sub-area and the position of the confluence line is greater than a first threshold value.

[0102] It should be noted that the preset proportion can be set as required. For example, the preset proportion can be 10% or the like.

[0103] In a possible embodiment, in order to adjust the filling flow direction, S304 in the improvement method of the application can further specifically include the following S501-S502.

[0104] S501, the underflow line improvement apparatus determines a target area according to the abnormal filling flow direction.

[0105] The abnormal filling flow direction is directed to one side of the position of the confluence line, and the target area is located on the other side of the position of the confluence line.

[0106] For example, in a case where the abnormal filling flow direction is the northeast direction, the underflow line improvement apparatus can determine that the target area is the left area of the position of the confluence line.

[0107] For another example, in a case where the abnormal filling flow direction is the northwest direction, the underflow line improvement apparatus can determine that the target area is the right area of the position of the confluence line.

[0108] S502, the underflow line improvement apparatus increases the wall thickness of the target area according to the first mapping relationship to adjust the filling flow direction.

[0109] The first mapping relationship is different angle difference and corresponding wall thickness. For example, in a case where the angle difference is 15 degrees, the corresponding wall thickness can be +1 mm, and in a case where the angle difference is 16 degrees, the corresponding wall thickness can be +2 mm.

[0110] It should be noted that the above first mapping relationship is only an exemplary description and is not limited.

[0111] In a possible embodiment, to obtain the model file of the target object, S301 in the method for improving the potential flow line can further include the following S601-S602.

[0112] S601, the potential flow line improvement device obtains three-dimensional data of the target object.

[0113] The three-dimensional data of the target object can reflect the installation structure, the reinforcing structure, the flanging structure, the wall thickness design, and the draft design of the target object.

[0114] As a possible implementation manner, the potential flow line improvement device can obtain the three-dimensional data of the target object in response to an input operation of a user. For example, the input operation can be an operation input by an operator through an input device (such as a keyboard) of a computer.

[0115] S602, the potential flow line improvement device processes the three-dimensional data by using a preset modeling software to obtain the model file of the target object.

[0116] The preset modeling software includes but is not limited to CADdoctor, HyperMesh, Moldex3D, and the like.

[0117] As a possible implementation manner, the potential flow line improvement device can perform CAE modeling on the three-dimensional data by using the preset modeling software to obtain the model file of the target object.

[0118] For example, the potential flow line improvement device can output a udm model file by using the CADdoctor modeling software.
