[0002] Plastic products are widely used in daily life due to their ease of molding, high design flexibility, and wide range of adjustable properties. However, as people's requirements for the appearance of plastic products become increasingly demanding, various problems may arise during the molding process due to structural or formulation design, leading to unacceptable products. Among these, pressure lines are a very typical surface defect, appearing as raised, tangible lines on the surface of plastic products. The presence of pressure lines reduces the appearance quality of plastic products, limiting their application and promotion.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0048] Figure 1 A flowchart of a pressure line warning method 100 according to an embodiment of the present disclosure is shown. Method 100 may include:
[0049] Step 110: Obtain the design and production parameters of the preset plastic product;
[0050] The design and production parameters of the product include, but are not limited to: 3D structural drawings of the product, the number and location of the product's gates and holes, process parameters (such as the temperature and pressure of the mold used to produce the product, the plastic temperature, the injection speed, holding pressure and duration during product molding, etc.), and material parameters of the product (such as the product's viscosity, PVT, thermal conductivity, specific heat capacity, etc.).
[0051] Step 120: Based on the design and production parameters, determine whether the preset plastic product has a pressure line risk, and obtain the determination result;
[0052] In one embodiment, the number of gates and holes of a pre-designed plastic product can be extracted from the design and production parameters. If the number of gates is greater than or equal to 2, the injection molding material is prone to uneven merging when it flows out of the gate and then merges again. Alternatively, if the number of gates is 1 and the number of holes is several, the gate is likely not in the center of the product, or the gate is in the center of the product but the holes are unevenly distributed relative to the gate, which leads to uneven merging of the injection molding material when it is separated from the gate and then merges again. Therefore, the judgment result is that the pre-designed plastic product has a pressure line risk. In this way, the presence of a pressure line risk in the pre-designed plastic product can be accurately determined based on the number of gates and holes.
[0053] Step 130: Use a pressure line verification mold to verify whether there is a pressure line risk in the injection molding material of the preset plastic product, and obtain the verification result;
[0054] The pressure line verification indicates that the mold contains two gates and has a hole in a non-central location, such as... Figure 3 , Figure 4 Middle left image or Figure 5 As shown.
[0055] The pressure line verification mold is a mold specifically designed for producing target plastic products based on the risks generated by the pressure line. The target plastic product and the pre-designed plastic product may not be the same product, and there are countless pre-designed plastic products.
[0056] In one embodiment, a pressure line verification mold can be installed on an injection molding machine, and then the injection molding machine can be used to produce a verification product (the verification product is the target plastic product, which may not be the same as the preset plastic product, and there are countless preset plastic products). This verifies the height distribution of the target plastic product produced by the injection molding machine after the injection material is injected into the injection molding machine following the installation of the pressure line verification mold. If the height distribution of the target plastic product is uniform, it indicates that the height of different positions of the target plastic product is the same or at least substantially the same. Therefore, the verification result is that the injection material does not have a pressure line risk. If the height distribution of the target plastic product is uneven, it indicates that the height difference of different positions of the target plastic product is too large, resulting in unevenness and thickness differences. Therefore, the verification result is that the injection material has a pressure line risk. In this way, the presence of a pressure line risk in the injection molding material itself can be accurately determined through the target plastic product injected by the injection molding machine.
[0057] Step 140: Based on the judgment result and the verification result, confirm whether to issue a pressure line warning.
[0058] In one embodiment, if the judgment result and the verification result are consistent and both indicate the presence of pressure line risk, it means that both the preset plastic product and the injection molding material have pressure line risk, and therefore, pressure line warning can be issued; otherwise, pressure line warning is not issued, thereby reducing pressure line defects in a timely manner, improving the production efficiency of the preset plastic product, and reducing the mold modification cost of the preset plastic product.
[0059] After obtaining the design and production parameters of the preset plastic product, it is possible to determine whether the preset plastic product has a pressure line risk based on the design and production parameters, and obtain the judgment result. Then, a pressure line verification mold is used to verify whether the injection molding material of the preset plastic product has a pressure line risk, and obtain the verification result. Based on the judgment result and the verification result, it is determined whether to issue a pressure line warning. In this way, by judging whether the preset plastic product and the injection molding material have a pressure line risk, pressure line defects can be predicted. This can improve the production efficiency of the preset plastic product while reducing the mold modification cost of the plastic product.
[0060] In some embodiments, confirming whether to issue a pressure line warning based on the judgment result and the verification result includes:
[0061] If the judgment result and the verification result are consistent and both indicate the existence of a pressure line risk, then a pressure line warning will be issued;
[0062] Otherwise, no pressure line warning will be issued.
[0063] If the judgment result and the verification result are consistent and both indicate the presence of pressure line risk, it means that both the pre-designed plastic product and the injection molding material have pressure line risk, and therefore, pressure line warning can be issued; otherwise, pressure line warning will not be issued, thereby reducing pressure line defects in a timely manner, improving the production efficiency of the pre-designed plastic product, and reducing the mold modification cost of the pre-designed plastic product.
[0064] In some embodiments, determining whether the preset plastic product has a pressure line risk based on the design and production parameters, and obtaining the determination result, includes:
[0065] Obtain the number of gates and holes for the pre-set plastic products in the design and production parameters;
[0066] If the number of gates is greater than or equal to 2, or if the number of gates is 1 and the number of holes is several, then the judgment result is that the preset plastic product has a pressure line risk.
[0067] The number of gates and holes for a pre-designed plastic product can be extracted from the design and production parameters. If the number of gates is greater than or equal to 2, the injection molding material is prone to uneven merging when it flows out of the gate and then merges again. Alternatively, if the number of gates is 1 and the number of holes is several, the gate is likely not in the center of the product, or the gate is in the center of the product but the holes are unevenly distributed relative to the gate, which leads to uneven merging of the injection molding material when it is divided and then merges again. Therefore, the judgment result is that the pre-designed plastic product has a pressure line risk. In this way, the presence of a pressure line risk in a pre-designed plastic product can be accurately determined based on the number of gates and holes.
[0068] In some embodiments, the step of using a pressure line verification mold to verify whether the injection molding material of the preset plastic product has a pressure line risk, and obtaining the verification result, includes:
[0069] The height distribution of the target plastic product produced by the injection molding machine is verified after the pressure line verification mold is installed in the injection molding machine and the injection material is injected into the injection molding machine.
[0070] If the height distribution of the target plastic product is uniform, the verification result is that the injection molding material does not have a pressure line risk.
[0071] If the height distribution of the target plastic product is uneven, the verification result indicates that the injection molding material has a risk of pressure lines.
[0072] A pressure line verification mold can be installed on an injection molding machine. The machine is then used to produce a verification sample (the target plastic product, which may not be the same as a pre-designed plastic product, and there are countless pre-designed plastic products). This verifies the height distribution of the target plastic product produced by the injection molding machine after the mold is installed and the injection material is injected. If the height distribution is uniform, it indicates that the heights at different locations are the same or at least substantially the same, thus the verification result is that the injection material does not have a pressure line risk. If the height distribution is uneven, it indicates that the height differences at different locations are too large, resulting in unevenness and thickness variations, thus the verification result is that the injection material has a pressure line risk. In this way, the presence of a pressure line risk in the injection molding material itself can be accurately determined through the target plastic product produced by the injection molding machine.
[0073] In some embodiments, the method further includes:
[0074] If a pressure line warning is confirmed, the target parameters of the preset plastic product are adjusted, wherein the target parameters include at least one of the following: gate parameters, structural parameters, and plastic product formulation parameters.
[0075] The gate parameters include: the number and location of the gates for the preset plastic product, and the opening / injection sequence of multiple gates;
[0076] Structural parameters include: the pre-defined shape of the plastic product, the location and arrangement of the holes, and the number of holes;
[0077] Plastic product formulation parameters include: the proportions of different materials in the injection molding material, etc.
[0078] The adjusted target parameters and the design and production parameters are input into the preset fluid simulation software to obtain the adjusted preset plastic product;
[0079] Determine whether the adjusted preset plastic product has pressure lines.
[0080] To determine whether a pressure line exists, the height distribution of the adjusted preset plastic product can be checked. If the height distribution is uniform or consistent, there is no pressure line. If the height distribution is uneven or inconsistent, then a pressure line exists.
[0081] If a pressure line warning is confirmed, the target parameters of the preset plastic product can be adjusted, such as adjusting the number and location of the gates, adjusting the material formula of the plastic product, etc., thereby optimizing the product filling behavior, reducing filling imbalance and reducing the risk of pressure line defects. Therefore, the adjusted target parameters and the design and production parameters can be input into the preset fluid simulation software, thereby simulating the adjusted preset plastic product using the preset fluid simulation software, and then determining whether the adjusted preset plastic product has pressure lines, thereby confirming whether the target parameters of the preset plastic product have been adjusted appropriately.
[0082] In some embodiments, the method further includes:
[0083] If the adjusted preset plastic product does not have pressure lines, then the corresponding plastic product mold is made using the adjusted preset plastic product.
[0084] If the adjusted preset plastic product does not have pressure lines, then the corresponding plastic product mold is made using the adjusted preset plastic product. In this way, since the adjusted preset plastic product is more accurate, the cost of modifying the plastic product mold can be reduced, and an accurate plastic product mold can be obtained quickly.
[0085] In some embodiments, the method further includes:
[0086] If the adjusted preset plastic product has pressure lines, the target parameters will be adjusted further, and the adjusted target parameters and the design and production parameters will be input into the preset fluid simulation software to obtain the adjusted preset plastic product.
[0087] Repeatedly determine whether the adjusted preset plastic product has pressure lines.
[0088] If the adjusted preset plastic product has pressure lines, the target parameters can be readjusted. Then, the readjusted target parameters and the design and production parameters are input into the preset fluid simulation software to obtain the adjusted preset plastic product. The software then re-determines whether the adjusted preset plastic product has pressure lines. If pressure lines exist, the target parameters are readjusted until the adjusted preset plastic product does not have pressure lines. Finally, the plastic product mold is made using the preset plastic product without pressure lines to improve the accuracy of the plastic product mold.
[0089] The following will combine Figure 2 Further details of the technical solution disclosed herein:
[0090] Step 1: Obtain product design and manufacturing parameters;
[0091] Step two: Determine whether there is a risk of pressure line based on the design parameters and process parameters;
[0092] Step 3: Use the pressure line verification mold to verify whether there is a risk of pressure lines in the injection molding material; Step 4: If both Step 2 and Step 3 are met, use fluid simulation software to analyze and optimize the product filling behavior, reduce filling imbalance and reduce the risk of pressure line defects.
[0093] Step 5: Output product design parameters, process parameters, and molding parameters.
[0094] The following will combine Figures 3 to 5 Further details of the technical solution disclosed herein:
[0095] This disclosure provides a verification mold for verifying defects in pressure lines. For example... Figure 3 The image shows the cavity portion of the mold, consisting of the front and rear molds. Holes (such as...) are present in the center and at the edges of this cavity. Figure 3 The three holes in the middle and the round holes on the edge will cause the flow front to split and then rejoin. At the same time, the cavity has two point gates (such as...). Figure 3 The two long tubes shown intersecting the mold surface (the pointed ends) will also cause the flow front to converge.
[0096] This disclosure also relates to a method for reducing pressure line defects. For example... Figure 2 As shown, the process begins by obtaining the product's design and production parameters. Then, based on these parameters, a preliminary assessment is made to determine if the product carries a risk of pressure lines. Next, a pressure line verification mold is used to verify whether the molding material (injection molding material) carries a risk of pressure lines. Then, fluid simulation software is used to analyze and optimize the product's filling behavior, reducing filling imbalance to mitigate the risk of pressure line defects. Finally, product design parameters, process parameters, and molding parameters are output to guide production.
[0097] The following are several practical production examples that verify and resolve pressure line defects.
[0098] Example 1
[0099] A certain product has high appearance requirements, and the injection molding material is specified as pure polypropylene (PP). Due to the shape and functional requirements, there is a hole on the side of the product. Reviewing the initial injection plan reveals that the gate position is unbalanced relative to the hole, and using this gate plan for mold making carries the risk of uneven thickness marks. To verify whether this material poses a risk of pressure lines, a verification mold was used for injection molding. After injection molding, no obvious pressure lines were found on the verification product. Based on the verification results, this product has no pressure line risk under the existing process conditions, and the design plan does not need to be modified.
[0100] Example 2
[0101] A certain product has high requirements for appearance and structure, such as Figure 4 As shown in the left image, the injection molding material is specified as 20% talc-filled polypropylene (PP). Due to the shape and functional requirements, there is a hole on the side of the product. Examining the initial injection plan reveals that the gate position is unbalanced relative to the hole (i.e., the gate is not on the center line of the hole). Figure 4 (At the connection point between the central tube and the cylinder), there is a risk of uneven thickness marks when using this gate design for mold making. To verify whether this material poses a risk of pressure lines, injection molding was performed using a verification mold. After injection molding, obvious pressure lines were found on the verification sample. To optimize the pressure line defect, the gate position was adjusted using simulation tools. Based on the simulated flow front convergence, it was found that adjusting the gate to the position opposite the orifice... Figure 4 As shown in the right figure (the gate is exactly on the center line of the hole), adjusting the gate position can effectively prevent secondary deflection of the flow velocity after the flow front of the injection molding material converges, thereby reducing the possibility of pressure lines. Based on the verification results, it is recommended to keep the molding process and materials unchanged and modify the product injection scheme.
[0102] Example 3
[0103] A certain product has high requirements for appearance and structure, such as Figure 5 The image shows a large flat plate, with the injection molding material specified as 30% talc-filled polypropylene (PP). The injection scheme is a three-gate simultaneous injection from the side. Although the product has no special structures such as pores, the initial injection scheme reveals that the simultaneous opening of the three gates will cause confluence between them, and the overall flow trend is towards both sides (i.e., after the injection material flows out from each gate, it merges with the first (or third) gate at the middle gate, and then flows towards the edge, causing a secondary confluence). Using this injection scheme for mold making (i.e., the plastic mold for the product) carries the risk of uneven thickness marks. To verify whether this material poses a risk of pressure lines, a verification mold was used for injection testing. After injection, obvious pressure lines were found on the verification sample. To optimize the pressure line defect, a simulation tool (i.e., preset fluid simulation software) was used to adjust the injection sequence (i.e., adjusting the gate opening order or injection sequence). The simultaneous opening of all three gates was changed to the middle gate opening first, and the other two gates opening only after the flow front has passed one distance past the outer gate. This injection scheme effectively avoids flow front convergence, thus reducing the likelihood of pressure lines (i.e., the middle gate is opened first, then the injection material flows through the first and third gates before opening the first and third gates again. This way, the injection material flowing out of the first and third gates is already filled with injection material in the area from the middle gate to the two side gates, and will not flow further towards the middle gate but only towards the side edges, naturally preventing secondary convergence and reducing the risk of pressure lines). Based on the verification results, it is recommended to keep the product structure and materials unchanged and modify the product injection scheme.
