[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.

[0026] like Figure 1 and Figure 2 As shown, according to an embodiment of the invention, a method for preventing deformation of a two-color injection molded part is provided, comprising the following steps:

[0027] Step S101: constructing a two-color injection molding simulation model according to a modeling method, wherein the modeling method includes two-color overlapping injection molding modeling, one-shot insert injection molding modeling, and two-shot insert injection molding modeling.

[0028] Step S101: obtaining an injection-molded simulation part through a two-color injection-molding simulation model.

[0029] Step S102: Analyze the injection-molded simulation part to obtain warpage data of the injection-molded simulation part.

[0030] Step S103: Determine a pre-deformation scheme according to the warping data.

[0031] Step S104: Modify the mold opening data and reserved data according to the pre-deformation scheme.

[0032] Step S105: Perform mold opening verification according to the modified data and the reserved data to obtain an injection molded workpiece.

[0033] Step S106: obtaining the actual deformation of the injection molded workpiece, wherein the actual deformation value is obtained by blue light scanning the actual part.

[0034] Step S107: If the actual deformation amount cannot meet the requirement, the mold opening data and the reserved data are adjusted until the actual deformation amount meets the requirement.

[0035] In this embodiment, the first color molding material of the two-color injection molding part is ABS, and the elastic modulus E1 is 2400Mpa, and the second color molding material is PMMA, and the elastic modulus E1 is 2740Mpa, and the material modulus difference is not large. Among them, polymethyl methacrylate (Polymethyl Methacrylate, gradient PMMA) is a high molecular polymer, also known as acrylic or organic glass, with the advantages of high transparency, low price, easy machining, etc., and is a commonly used glass substitute material.

[0036] Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic polymer structural material with high strength, good toughness and easy processing and molding, also known as ABS resin.

[0037] The injection molding simulation part is obtained through the two-color injection molding simulation model. According to the two-color product material combination table, the material combination that may need pre-deformation is selected as the first color material is hard glue plus fiber, and the second color material is software. The elements of pre-deformation deformation are analyzed: process, trend, deformation amount, digital model 3D, and the difficulty level of two-color pre-deformation is divided into: 1D direction pre-deformation, 2D surface pre-deformation and 3D surface pre-deformation.

[0038] When the material combination is a hard rubber with one color and fiber-added material, and the modulus difference between the two-color materials is large, the deformation of the two-color product is mainly affected by the one-color product with high modulus and high strength. The one-color with low modulus has a certain influence on the deformation. It is necessary to determine whether the deformation trend has a positive or negative impact in order to determine the pre-deformation amount. The key to successful pre-deformation is to determine the deformation trend of the one-color product with high modulus. The fiber-added product is prone to the opposite deformation phenomenon, which leads to mold failure.

[0039] When there is no experience, the working conditions that are closer to the actual deformation can be simulated according to the different material moduli. For complex deformation conditions in multiple directions, the deformation amounts in the three directions of X / Y / Z of MF can be simplified from 3D direction to 1D direction, thus simplifying the difficulty of pre-deformation processing.

[0040] Based on step S102, the injection molded simulation part is analyzed to obtain the warpage data of the injection molded simulation part, which specifically includes the following steps:

[0041] Step S1021: performing mold flow analysis on the injection molding simulation part to determine the deformation amount.

[0042] Step S1022: obtaining warping data according to the deformation amount.

[0043] Furthermore, the user-defined boundary parameters are verified before the injection molding simulation parts are obtained through the two-color injection molding simulation model. The user-defined boundary parameters are referred to as UDB. The material UDB has the greatest impact on the simulation deformation, affecting the deformation amount and deformation trend. There will be problems when the customer provides UDB. Verify the accuracy of UDB before analysis, use substitution for analysis and verification, and perform material testing if necessary. After UDB verification, the simulation obtains theoretical results. Among them, it is necessary to interpret the warpage data according to the material classification.

[0044] Based on step S106, a mold flow analysis is performed on the injection molding simulation part to determine the deformation amount, which specifically includes the following steps:

[0045] Step S1061: Perform positive molding by using a two-color injection molding simulation model to obtain a first simulation part.

[0046] Step S1062: Perform flip-chip molding through the two-color injection molding simulation model to obtain a second simulation part.

[0047] Step S1063: Analyze the first simulation component and the second simulation component to determine the deformation amount.

[0048] The deformation of the high-gloss mold flip-up process is relatively larger than that of the upright mold, and the pre-deformation treatment is more complicated. Among them, the adjustment of the injection position has little effect on the deformation of the B-pillar. Optimizing the gate position can reduce the volume shrinkage of the terminal.

[0049] Based on step S106, a mold flow analysis is performed on the injection molding simulation part to determine the deformation amount, which specifically includes the following steps:

[0050] Step S1064: Perform pressure holding analysis on the injection molding simulation part to obtain pre-deformation data.

[0051] Step S1065: Obtain the deformation amount according to the pre-deformation data.

[0052] Adjust different combination parameters to get the corresponding simulation deformation. The greater the ABS pressure, the more warped the product is; the longer the ABS time, the more warped the product is; the greater the PMMA pressure, the more curved the product is; the longer the PMMA time, the more curved the product is. Mainly adjust the ABS pressure: the greater the ABS pressure, the better the deformation; the greater the pressure, the worse the shape deviation; the ABS holding pressure cannot be greater than 60MPA; the smaller the pressure, the slighter the shape deviation of the double-layer guide rail. For example, according to the large holding pressure analysis, the part deformation is 1.5mm, the Z-direction mold pre-deformation is 1.5mm, the actual part size meets the requirements, and the shape deviation is NG. According to the actual shape deviation OK process analysis, the part deformation is 4mm, the Z-direction mold pre-deformation is 1.5mm, the part deformation is 2.5mm, the analysis result is consistent with the actual, and the size is NG.

[0053] Further, the deformation amount includes deformation data in three-dimensional directions.

[0054] Based on step S103, a pre-deformation scheme is determined according to the warping data, which specifically includes the following steps:

[0055] Step S1031: Obtain the deformation before glue reduction by tilting the injection simulation part according to the warpage data.

[0056] Step S1032: performing a glue reduction process on the inclined top of the injection-molded simulation part to obtain the deformation amount after the glue reduction, and the warpage data includes the deformation amount before the glue reduction and the deformation amount after the glue reduction.

[0057] Step S1033: According to the deformation amount before and after the reduction of the glue, the pre-deformation scheme is determined to be the inclined top and the reduced wall thickness.

[0058] Reducing the wall thickness can optimize the curvature deformation of the product. For example, the inclined top is reduced to 1.1mm, and the Z-direction dimension of the part meets the requirements. Referring to the front of the B-pillar, the inclined top is reduced by 1mm, and the warping is not improved. Replacing the glass fiber filling by 10% can improve the warping.

[0059] Based on step S103, a pre-deformation scheme is determined according to the warping data, which specifically includes the following steps:

[0060] Step S1034: When performing injection molding through the two-color injection molding simulation model, ABS materials with different fluidities are injected to obtain corresponding different injection molding simulation parts.

[0061] Step S1035: performing pressure comparison on the injection molding simulation part to obtain a pressure comparison result.

[0062] Step S1036: Obtain the corresponding volume shrinkage rate according to the pressure comparison result, and the warpage data includes the volume shrinkage rate.

[0063] Step S1037: Determine the pre-deformation scheme according to the volume shrinkage rate.

[0064] The pressure comparison results of different fluidity of ABS materials can be analyzed. When the fluidity of ABS materials is improved, the volume shrinkage changes significantly, and when the volume shrinkage changes, the deformation changes significantly. For example, when the ABS melt index is increased from 7 to 14.3, the actual injection pressure is improved less, and the final mold solution is obtained: the mold is remade with a pre-deformation of 4mm.

[0065] The deformation amount is determined. The process window frame of the upright mold is wider, and the process window frame of the inverted mold is smaller. The mold flow simulation cannot reflect the part drop and mold deviation. Based on the actual situation, it is necessary to standardize the process settings for analysis and avoid the process that causes mold deviation in advance for analysis. The product has deformation in the X and Z directions. Pre-deformation treatment is performed after obtaining the accurate deformation amount.

[0066] Whether it is a positive or inverted high-gloss mold, the mold flow analysis must be used to obtain accurate deformation, and the mold must be pre-deformed in advance. The deformation problem cannot be corrected in the later process, and the modification cost incurred by subsequent mold modification is relatively large.

[0067] like Figure 3 As shown, the present invention also provides an electronic device, comprising: at least one processor 110; a memory 120 communicatively connected to the at least one processor; wherein the memory 120 stores instructions executable by the at least one processor 110, and the instructions are executed by the at least one processor 110 so that the at least one processor 110 can implement the following steps:

[0068] Step S101: constructing a two-color injection molding simulation model according to a modeling method, wherein the modeling method includes two-color overlapping injection molding modeling, one-shot insert injection molding modeling, and two-shot insert injection molding modeling.

[0069] Step S101: obtaining an injection-molded simulation part through a two-color injection-molding simulation model.

[0070] Step S102: Analyze the injection-molded simulation part to obtain warpage data of the injection-molded simulation part.

[0071] Step S103: Determine a pre-deformation scheme according to the warping data.

[0072] Step S104: Modify the mold opening data and reserved data according to the pre-deformation scheme.

[0073] Step S105: Perform mold opening verification according to the modified data and the reserved data to obtain an injection molded workpiece.

[0074] Step S106: obtaining the actual deformation of the injection molded workpiece.

[0075] Step S107: If the actual deformation amount cannot meet the requirement, the mold opening data and the reserved data are adjusted until the actual deformation amount meets the requirement.
