[0054] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0055] Referring to Figure 1 As shown, in some embodiments of the present application, this embodiment provides a method for manufacturing an insole core mold, including:

[0056] S100: Collect the flatness of the initial sample paper, determine whether to polish the initial sample paper according to the flatness to obtain the target sample paper, obtain the insole sample paper from the target sample paper, perform standard processing on the insole sample paper, determine the target insole based on the standard processing result, and determine the 2D model of the insole core according to the target insole;

[0057] S200: Obtain the material properties of the material to be manufactured, determine the material comprehensive value of the material to be manufactured according to the material properties, compare the material comprehensive value with the historical data, and determine whether the material to be manufactured meets the mold manufacturing according to the comparison result. When it is determined that it meets the mold manufacturing, perform 3D design based on the 2D model to determine the three-dimensional data of the insole core;

[0058] S300: Import the three-dimensional data and the material to be manufactured that meets the mold manufacturing into a CNC numerical control machine tool, obtain multiple ambient temperature values at the same time, and obtain the processing temperature value of the processing and manufacturing. Determine the processing temperature curve according to the relationship between each ambient temperature value and the processing temperature value, determine the number of temperature inflection points according to the processing temperature curve, and determine the temperature evaluation value according to the number of temperature inflection points;

[0059] S400: Determine the temperature adjustment coefficient of the processing temperature value according to the temperature evaluation value, adjust the processing temperature value according to the temperature adjustment coefficient, and complete the mold manufacturing according to the adjusted processing temperature value.

[0060] Specifically, an initial sample paper is photographed using a photographing device such as a camera, and the obtained image data is analyzed to determine the flatness of the initial sample paper. The flatness of the initial sample paper directly determines the precision of the insole core mold manufacturing. If the flatness of the initial sample paper does not meet the standard, it will cause errors in the mold design process, thereby affecting the quality of the insole core. The user's feet are stepped on and cut on the target sample paper that meets the flatness to obtain the insole sample paper, and the insole sample paper is subjected to standard processing, including correcting the size and shape, ensuring that the target insole meets the design requirements of the mold manufacturing. The actual parameters of the target insole are designed using digital modeling software to obtain the 2D model of the insole core, providing accurate size and proportion references for subsequent three-dimensional design. Different materials have different material properties. Selecting the appropriate material to be manufactured can ensure the success rate of mold manufacturing. By calculating the material comprehensive value of the material to be manufactured and comparing it with historical data, it can help determine whether the material to be manufactured is suitable for mold manufacturing, reducing the risk of mold accuracy decline caused by unqualified materials to be manufactured. If the material to be manufactured is qualified, 3D design is carried out on three-dimensional software according to the 2D model to obtain the three-dimensional data of the insole core.

[0061] It can be understood that according to the relationship between multiple ambient temperature values and processing temperature values at the same moment, the processing temperature curve is determined. Preferably, 20 ambient temperature values are obtained, which can be adjusted according to actual manufacturing requirements. The processing temperature curve can clearly show the changes between the processing temperature value and the ambient temperature value during the processing, thereby obtaining the temperature evaluation value, laying a data foundation for subsequent analysis. The temperature evaluation value measures the impact of the temperature change on mold processing, thereby judging whether the processing temperature value is appropriate and avoiding the impact of ambient temperature fluctuations on the quality of mold manufacturing. Moreover, according to the temperature evaluation value, the temperature adjustment coefficient of the processing temperature value is determined, and the processing temperature value is dynamically adjusted to ensure the precision and stability of the mold manufacturing process, and further ensure the consistency and repeatability of the insole core mold in each insole core manufacturing.

[0062] In some embodiments of the present application, when judging whether to polish the initial sample paper according to the flatness, it includes:

[0063] Preset the standard flatness, compare the flatness with the standard flatness, and judge whether to polish the initial sample paper according to the comparison result;

[0064] When the flatness is greater than or equal to the standard flatness, it is determined not to polish the initial sample paper;

[0065] When the flatness is less than the standard flatness, it is determined to polish the initial sample paper.

[0066] In some embodiments of the present application, when performing standard processing on the insole template and determining the target insole based on the standard processing results, it includes:

[0067] Obtain the size values of the insole template for several times, where the size values include the length of the insole template and the width of the insole template;

[0068] The standard processing includes obtaining the average value of the length of the insole template, obtaining the average value of the width of the insole template, and performing a circumferential reduction on the average value of the length of the insole template and the average value of the width of the insole template;

[0069] Determine the target insole according to the average value of the length of the insole template, the average value of the width of the insole template, and the result of the circumferential reduction.

[0070] Specifically, by judging the flatness of the initial template, the reliability of the target template is ensured to be high, and the accuracy of subsequent mold production is guaranteed. After the user steps on the target template that meets the flatness and performs cutting to obtain the insole template, by obtaining the size values of the insole template for several times, the average value of the length of the insole template and the average value of the width of the insole template can be accurately obtained, which helps to eliminate the random error of measuring the insole template and improves the size accuracy of the target insole. Moreover, a circumferential reduction is performed on the average value of the length of the insole template and the average value of the width of the insole template. The circumferential reduction is to reduce 3 mm on the average value of the length of the insole template and the average value of the width of the insole template. The target insole is determined according to the average value of the length of the insole template, the average value of the width of the insole template, and the result of the circumferential reduction, providing accurate mold parameters for subsequent mold production.

[0071] In some embodiments of the present application, when determining the material comprehensive value of the material to be manufactured according to the material properties, it includes:

[0072] The material properties include material hardness, material density, material thickness, material tensile strength, and material compressive strength;

[0073] The material comprehensive value is obtained from the following formula:

[0074]

[0075] Among them, C represents the material comprehensive value, K represents the material hardness, σ t represents the material tensile strength, σ c represents the material compressive strength, ρ represents the material density, and H represents the material thickness.

[0076] In some embodiments of the present application, when comparing the material comprehensive value with historical data and judging whether the material to be manufactured meets the mold production according to the comparison result, it includes:

[0077] Historical data includes the comprehensive value of historical qualified materials, the comprehensive value of historical primary materials, and historical materials to be manufactured. The comprehensive value of historical primary materials corresponds to the historical materials to be manufactured, and the comprehensive value of historical primary materials is greater than or equal to the comprehensive value of historical qualified materials;

[0078] Compare the comprehensive material value with the comprehensive value of historical qualified materials, and determine whether the materials to be manufactured meet the requirements for mold manufacturing according to the comparison result;

[0079] When the comprehensive material value is greater than or equal to the comprehensive value of historical qualified materials, it is determined that the materials to be manufactured meet the requirements for mold manufacturing;

[0080] When the comprehensive material value is less than the comprehensive value of historical qualified materials, it is determined that the materials to be manufactured do not meet the requirements for mold manufacturing, and the historical materials to be manufactured are determined as the materials to be manufactured.

[0081] Specifically, by comprehensively considering the material properties of the materials to be manufactured, calculating the comprehensive material value of the materials to be manufactured, which can accurately reflect its effect in mold manufacturing, so as to ensure that the selected materials to be manufactured have balance in terms of hardness, tensile strength, compressive strength, etc., providing a reliable material basis for mold manufacturing. Moreover, calculating the comprehensive material value avoids one-sided evaluation of the overall material performance by single material characteristics and avoids quality problems of the mold caused by unbalanced material characteristics. The comprehensive value of historical qualified materials is set according to actual manufacturing requirements. By comparing with the comprehensive value of historical qualified materials in historical data, it can ensure that the materials to be manufactured meet the standard requirements of mold manufacturing. Only when the comprehensive material value of the materials to be manufactured is greater than or equal to the comprehensive value of historical qualified materials, it is determined to meet the manufacturing requirements of the mold. And when the comprehensive material value is less than the comprehensive value of historical qualified materials, by finding the data of successfully manufactured molds in historical data and taking the corresponding historical materials to be manufactured as the materials to be manufactured, a good material traceability system can be formed to ensure that the materials to be manufactured for mold manufacturing always meet the quality requirements.

[0082] It can be understood that through the comprehensive calculation of material properties and comparison with historical data, it can ensure that the quality of the materials to be manufactured during mold manufacturing meets the standard requirements, thereby improving the quality and service life of the mold, and further improving the accuracy and reliability of the mold.

[0083] In some embodiments of the present application, when obtaining multiple environmental temperature values at the same time, determining the processing temperature value for processing and manufacturing, and determining the processing temperature curve according to the relationship between each environmental temperature value and the processing temperature value, it includes:

[0084] Obtain the difference between the processing temperature value and each environmental temperature value, and record it as the temperature compensation value;

[0085] Take the unit temperature compensation value as the y-axis of the processing temperature curve, and take the number of times of obtaining the ambient temperature value per unit as the x-axis of the processing temperature curve to construct the coordinate system of the processing temperature curve;

[0086] Substitute all the temperature compensation values into the coordinate system, determine the coordinate points of each temperature compensation value, and connect the adjacent coordinate points to obtain the processing temperature curve.

[0087] In some embodiments of the present application, when determining the number of temperature inflection points according to the processing temperature curve, it includes:

[0088] Preset a temperature compensation threshold, and determine a parallel line parallel to the x-axis according to the temperature compensation threshold;

[0089] Obtain the number of temperature inflection points with slope changes above the parallel line and record it as the high-temperature compensation number, and obtain the number of temperature inflection points with slope changes below the parallel line and record it as the low-temperature compensation number.

[0090] Specifically, by establishing the processing temperature curve, the influence of different ambient temperatures on the processing of the mold can be measured. When obtaining the ambient temperature value, a single ambient temperature value is easily affected by random errors. Obtaining multiple ambient temperature values at the same moment effectively avoids the influence of random errors on the ambient temperature value, thereby improving the accuracy of the temperature compensation value. The unit temperature compensation value is preferably 0.5 °C, and the y-axis of the processing temperature curve is established incrementally based on this, while the x-axis of the processing temperature curve represents the number of times of obtaining the ambient temperature value per unit. For example: when obtaining the ambient temperature value for the first time, substitute all the temperature compensation values into the coordinate system, determine the coordinate points of each temperature compensation value. Each coordinate point of the temperature compensation value represents the temperature compensation value obtained when obtaining the ambient temperature value for the i-th time. Connect the adjacent coordinate points in pairs to form the processing temperature curve. Moreover, preset a temperature compensation threshold and determine a parallel line parallel to the x-axis according to the temperature compensation threshold. The temperature compensation threshold can be set according to actual processing requirements. This parallel line reflects the fluctuation of the processing temperature curve. The temperature inflection point with a slope change above the parallel line indicates that the fluctuation is greater than the set temperature compensation threshold, and the temperature inflection point with a slope change below the parallel line indicates that the fluctuation is less than the set temperature compensation threshold. If the fluctuation is equal to the set temperature compensation threshold, this coordinate point is not counted. By counting the high-temperature compensation number and the low-temperature compensation number, the influence of the fluctuation of the ambient temperature on the processing temperature value during the processing of the mold can be effectively determined, laying a foundation for the subsequent adjustment of the processing temperature value.

[0091] In some embodiments of the present application, when determining the temperature evaluation value according to the number of temperature inflection points, it includes:

[0092] The temperature evaluation value is obtained from the following formula:

[0093]

[0094] Among them, M represents the temperature evaluation value, B 1 represents the high-temperature compensation quantity, B 2 represents the low-temperature compensation quantity, and α and β represent weight coefficients, and the value ranges of α and β are (0, 1].

[0095] In some embodiments of the present application, when determining the temperature adjustment coefficient of the processing temperature value according to the temperature evaluation value and adjusting the processing temperature value according to the temperature adjustment coefficient, it includes:

[0096] Preset a first preset temperature evaluation value and a second preset temperature evaluation value, and the first preset temperature evaluation value is greater than the second preset temperature evaluation value;

[0097] Preset a first preset temperature adjustment coefficient T1, a second preset temperature adjustment coefficient T2, and a third preset temperature adjustment coefficient T3, and 0.5 < T3 < T2 < T1 < 1.2;

[0098] When the temperature evaluation value is greater than the first preset temperature evaluation value, use the first preset temperature adjustment coefficient T1 as the temperature adjustment coefficient of the processing temperature value;

[0099] When the temperature evaluation value is less than or equal to the first preset temperature evaluation value and greater than the second preset temperature evaluation value, use the second preset temperature adjustment coefficient T2 as the temperature adjustment coefficient of the processing temperature value;

[0100] When the temperature evaluation value is less than or equal to the second preset temperature evaluation value, use the third preset temperature adjustment coefficient T3 as the temperature adjustment coefficient of the processing temperature value;

[0101] The temperature adjustment coefficient and the processing temperature value are in a proportional relationship.

[0102] Specifically, according to different temperature evaluation values, an appropriate temperature adjustment coefficient can be dynamically selected, ensuring that the processing temperature value can be adjusted accordingly according to the change of the ambient temperature, thereby meeting the temperature requirements of processing and manufacturing, avoiding errors in mold manufacturing caused by changes in the ambient temperature, improving the flexibility and stability of the adjustment of the processing temperature value, and enhancing the adaptability of the mold in processing and manufacturing at different ambient temperatures. If the processing temperature value is T, the adjusted processing temperature value is determined to be T * Ti, where Ti represents one of the first preset temperature adjustment coefficient T1, the second preset temperature adjustment coefficient T2, and the third preset temperature adjustment coefficient T3. When it is necessary to increase or decrease the processing temperature value, corresponding adjustments are made according to the temperature adjustment coefficient, realizing precise control of the processing temperature value, effectively reducing the production impact caused by the ambient temperature, and thus improving the accuracy and reliability of mold manufacturing.

[0103] In summary, the beneficial effects of the present invention are as follows: By comprehensively evaluating the material properties of the material to be manufactured, obtaining the comprehensive material value and comparing it with historical data, it is possible to accurately determine whether the material to be manufactured meets the requirements of mold manufacturing, avoiding the interference of single attributes on the selection of the material to be manufactured, ensuring the reliability of the material to be manufactured, thereby improving the precision and stability of mold manufacturing, and further ensuring the quality of the insole core mold. By obtaining the relationship between multiple ambient temperature values and processing temperature values and analyzing the processing temperature curve, dynamically selecting the temperature adjustment coefficient of the processing temperature value, avoiding the influence of ambient temperature fluctuations on mold processing and manufacturing, ensuring the stability of the processing temperature during the manufacturing process, and avoiding the risk of mold deformation, thereby improving the precision and reliability of the insole core mold.
