Detailed Implementation

[0018] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0019] Due to differences in material shrinkage rates, uneven mold temperature distribution, and insufficient holding time, plastic parts often warp after demolding and cooling, leading to the following problems: 1) Difficulty in assembling parts, resulting in gaps, interference, or snap-fit ​​breakage; 2) Uneven surfaces on the surfaces of consumer electronics, automotive parts, and home appliances, affecting product aesthetics; 3) Accumulated assembly stress, reducing the overall structural strength of the product; 4) The need for repeated mold trials and repairs, extending the product development cycle and increasing costs. The common approach to addressing this warping in plastic parts involves repeatedly adjusting, testing, and repairing the corresponding mold. However, this method not only extends the product development cycle and increases costs but is also inefficient and fails to effectively resolve the warping problem and its associated issues.

[0020] To address the problems in the prior art, this application provides a simulation method, apparatus, electronic device, and medium for products containing plastic parts. This method can effectively identify plastic parts with warping deformation, correct the warping deformation, and replace the original product model's plastic parts with the corrected plastic parts. This simulation processing method can significantly shorten the product development cycle, effectively reduce costs, and is highly efficient, effectively solving the problems caused by warping deformation of plastic parts.

[0021] Example 1 See Figure 1 , Figure 1 This is a flowchart illustrating the simulation method for a product containing plastic parts provided in the embodiments of this application.

[0022] The simulation method for products containing plastic parts described in this application embodiment can be applied to computer equipment such as servers.

[0023] This application provides a simulation method for a product containing plastic parts, comprising the following steps: Step S110: Obtain the original product model of the target product, and obtain all plastic parts of the target product from the original product model.

[0024] In this embodiment, the product containing plastic parts can be a consumer electronics product, an automotive part, a home appliance product, etc.; the plastic parts can refer to plastic parts manufactured using injection molding process.

[0025] In this embodiment, the original product model of the target product, namely the three-dimensional product model of the target product, is composed of various parts, including plastic parts. For example, when obtaining all plastic parts of the target product from the original product model of the target product, the parts of the original product model of the target product can be disassembled, and all plastic parts of the target product can be obtained by identifying all disassembled parts; alternatively, when identifying all disassembled parts and obtaining all plastic parts of the target product, all disassembled parts can be identified and obtained by identifying all disassembled parts based on the material information of all disassembled parts.

[0026] Step S120: Establish the finite element model corresponding to each plastic part, and set the corresponding injection molding condition information and material performance parameters according to each plastic part.

[0027] In this embodiment, a finite element model corresponding to each plastic part is established based on the principle of finite element analysis. Finite element analysis (FEA) is a numerical technique based on mathematical mechanics principles that uses discretization to solve complex engineering problems and approximate solutions to differential equations in scientific research. Its core is to divide the continuous solution domain into a finite number of interconnected simple elements, establish nodal equilibrium equations and introduce boundary conditions, and finally obtain the nodal displacements and the overall field solution.

[0028] In this embodiment, each plastic part has corresponding injection molding condition information and material performance parameters. When setting the injection molding condition information and material performance parameters corresponding to each plastic part, the settings can be made by obtaining the injection molding condition information and material performance parameters corresponding to each plastic part entered by the staff. The injection molding condition information may include at least one of the following: structural information of the injection system corresponding to the plastic part, injection molding processing information, structural information of the cooling system, and cooling treatment information; preferably, the injection molding condition information includes structural information of the injection system corresponding to the plastic part, injection molding processing information, structural information of the cooling system, and cooling treatment information. Specifically, the structural information of the injection system can include the type of runner (cold runner or hot runner) and the injection location. Different runner types and injection locations have different effects on the warpage of plastic parts. Injection molding information includes melt temperature, injection time, and holding pressure profile. The holding pressure profile is a curve relating to holding pressure and holding time points. Different melt temperatures, injection times, and holding pressure profiles also have different effects on the warpage of plastic parts. The structural information of the cooling system includes the routing of the cooling circuit, i.e., how the cooling circuit is set up. Uneven cooling is a major cause of warpage in plastic parts, and different cooling circuit routings will... Uneven cooling in different areas of the mold can lead to varying cooling rates. Cooling information includes coolant type and flow rate. Coolant types are mainly divided into water and oil, which differ in heat transfer coefficient, specific heat capacity, temperature range, cooling rate, and temperature control accuracy. Water cools rapidly, making it more prone to deformation because its high heat transfer capacity can cause uneven cooling and inconsistent shrinkage, thus affecting deformation. Oil, on the other hand, cools more evenly and is better suited for controlling deformation. Therefore, different media have different effects on deformation. As for coolant flow rate, a flow rate that is too low can cause uneven cooling and increase the risk of deformation, while a flow rate that is too high will cool too quickly but may exacerbate deformation.

[0029] The material performance parameters of plastic parts mainly refer to the materials and properties of the plastic parts. The material properties of plastic parts can include parameters such as material shrinkage rate. The warping deformation of plastic parts is caused by uneven internal stress distribution during the cooling process. This stress distribution is mainly determined by the material properties. Therefore, the same plastic part will have different warping deformation when using different materials.

[0030] By using the above method, the injection molding condition information of plastic parts is set to include the structural information of the injection system, injection molding process information, cooling system, and cooling treatment information corresponding to the plastic parts. This fully considers the key factors affecting the warpage deformation of plastic parts, which is more conducive to the analysis of warpage deformation of plastic parts and makes the obtained warpage deformation data of plastic parts more accurate. Furthermore, by clarifying the specific information of the injection system, injection molding process information, cooling system, and cooling treatment information, the various influencing factors on the warpage deformation of plastic parts are fully considered, which can further improve the accuracy of the warpage deformation analysis of plastic parts and make the obtained warpage deformation data of plastic parts more precise.

[0031] Step S130: Based on the injection molding condition information and material performance parameters corresponding to each plastic part, solve the finite element model corresponding to each plastic part to obtain the warpage deformation data corresponding to each plastic part.

[0032] In this embodiment, when solving the finite element model corresponding to each plastic part, a direct method (such as Gaussian elimination method) or an iterative method (such as conjugate gradient method) can be used. The warpage deformation data obtained for each plastic part can be represented by the nodal displacement data or deformation field contour map corresponding to each plastic part.

[0033] Step S140: Based on the warpage deformation data corresponding to each plastic part, perform warpage correction on each plastic part, and replace the plastic parts of the original product model with the warpage-corrected plastic parts.

[0034] In this embodiment, when performing warpage correction on each plastic part based on the warpage deformation data corresponding to each plastic part, the corresponding warpage deformation result can be extracted based on the warpage deformation data (nodal displacement data or deformation field cloud map) corresponding to each plastic part, and then the warpage correction can be performed on each plastic part based on the corresponding warpage deformation result; wherein, the warpage deformation result can indicate the location of the plastic part where warpage deformation occurs and the warpage deformation situation at each location where warpage deformation occurs.

[0035] The simulation method for products containing plastic parts in this application embodiment can be applied to the overall design stage of products containing plastic parts. It establishes a finite element model corresponding to each plastic part of the original product model of the target product, and sets corresponding injection molding condition information and material performance parameters for each plastic part. Then, based on the injection molding condition information and material performance parameters corresponding to each plastic part, the finite element model corresponding to each plastic part is solved, thereby effectively determining the warpage deformation data corresponding to each plastic part of the original product model of the target product. Furthermore, based on the warpage deformation data corresponding to each plastic part, warpage correction is performed on each plastic part, and the warpage-corrected plastic part replaces the plastic part of the original product model. This simulation processing method can greatly reduce the number of times mold adjustments, trial moldings, and mold repairs are performed. Moreover, this simulation processing method can significantly shorten the product development cycle, effectively reduce product development costs, and is highly efficient, effectively solving problems caused by warpage deformation of plastic parts.

[0036] As an optional implementation, after obtaining the original product model of the target product, obtaining all plastic parts of the target product from the original product model, and before establishing the finite element model corresponding to each plastic part, the simulation method for products containing plastic parts in this application embodiment may further include the following steps: Inspect each plastic part for defects; When at least one plastic part is defective, the defective plastic part shall be repaired.

[0037] Specifically, whether a plastic part is defective can be understood as whether the plastic part is complete, or whether it is damaged or has missing parts. When a defective plastic part is detected, the defect is repaired to restore each defective plastic part to its original, defect-free form.

[0038] By repairing defective plastic parts using the above methods, it is more conducive to the analysis of warpage deformation of plastic parts, and the obtained warpage deformation data of plastic parts is more accurate, thus not affected by the defects of plastic parts.

[0039] As an optional implementation, when performing warpage correction on each plastic part based on the warpage deformation data corresponding to each plastic part, the warpage correction is performed in reverse compensation based on the warpage deformation data corresponding to each plastic part.

[0040] Understandably, warp correction with reverse compensation is performed on each plastic part. That is, if a certain position of a plastic part has a certain degree of warp deformation (e.g., protruding by a certain size), then warp correction with reverse compensation is performed on that position of the plastic part (e.g., the size corresponding to the depression).

[0041] By using the above method to perform reverse compensation warpage correction on each plastic part, the warpage correction of the plastic part can be effectively corrected, and this warpage correction method can better cope with the warpage deformation of the plastic part.

[0042] As an optional implementation method, see [link to implementation details]. Figure 2 After solving the finite element model for each plastic part based on the injection molding condition information and material performance parameters corresponding to each plastic part to obtain the warpage deformation data for each plastic part, and before performing warpage correction on each plastic part based on the warpage deformation data, the simulation method for products containing plastic parts in this application embodiment may further include the following steps: Step S210: Determine whether the warpage deformation data corresponding to each plastic part is within the corresponding warpage deformation range; Step S220: When the warpage deformation data of a plastic part exceeds the corresponding warpage deformation range, optimize the injection molding condition information of the plastic part. Step S230: Based on the optimized injection molding condition information and material performance parameters of the plastic part, solve the finite element model corresponding to the plastic part to obtain the updated warpage deformation data of the plastic part.

[0043] Specifically, the warpage range for each plastic part is preset. This range can include the location where warpage occurs and the shape and size of the warpage at that location. When determining whether the warpage data for each plastic part is within the corresponding warpage range, it can be determined whether the location where warpage occurs is within a predetermined deviation range from the predetermined location, whether the shape of the warpage matches the predetermined shape, and whether the size of the warpage is within a predetermined size difference from the predetermined size. If any one of these conditions is not met, the warpage data for the plastic part is determined to exceed the corresponding warpage range.

[0044] When optimizing the injection molding process information corresponding to the plastic part, at least one type of information can be optimized, including the structural information of the injection system, the injection molding process information, the structural information of the cooling system, and the cooling treatment information corresponding to the plastic part.

[0045] Understandably, when the updated warp deformation data of the plastic part is obtained, the updated warp deformation data of the plastic part is used to replace the initially obtained warp deformation data.

[0046] By using the above methods to determine whether the warpage data of the plastic parts is within the corresponding warpage range, and to optimize the injection molding process information of the plastic parts, we can avoid the situation where the warpage of the plastic parts is too severe and unacceptable. This can provide better assurance for product development and subsequent product testing and manufacturing. Furthermore, it can make the warpage analysis of plastic parts more reasonable and accurate.

[0047] As a preferred option, see Figure 3 When optimizing the injection molding condition information corresponding to the plastic part, multiple sets of different injection molding condition information corresponding to the plastic part can be optimized. When solving the finite element model of the plastic part based on the optimized injection molding process information and material performance parameters, and obtaining the updated warpage deformation data of the plastic part, the following may be included: Step S231: Based on the optimized injection molding condition information and material performance parameters of the plastic part, solve the finite element model corresponding to the plastic part to obtain the optimized warping deformation data of the plastic part. Step S232: Select the optimal warp deformation data from the multiple optimized warp deformation data of the plastic part as the updated warp deformation data.

[0048] Specifically, when selecting the optimal warp deformation data from multiple optimized warp deformation data of the plastic part as the updated warp deformation data, the warp deformation data with the smallest warp deformation among the multiple optimized warp deformation data can be selected as the updated warp deformation data.

[0049] By using the above method, the optimal situation for warping deformation of plastic parts can be obtained. Using the warping deformation data corresponding to the optimal situation for warping deformation to correct the plastic parts is more reasonable. Furthermore, it can minimize the possible impact after correction and better ensure the quality of the target product.

[0050] As an optional implementation, the simulation method for products containing plastic parts in this application embodiment can assemble the warped plastic parts to the original product model of the target product to form an updated product model of the target product, and perform the simulation tests required for the target product using the updated product model of the target product.

The finite element analysis module 420 is also used to solve the finite element model corresponding to each plastic part based on the injection molding condition information and material performance parameters corresponding to each plastic part, and obtain the warpage deformation data corresponding to each plastic part. The correction module 430 is used to correct the warpage of each plastic part based on the warpage deformation data corresponding to each plastic part, and replace the plastic parts of the original product model with the warpage-corrected plastic parts.
