Description

Technical Field

[0001] The present invention relates to the technical field of sole manufacturing equipment, in particular to a compression molding manufacturing device for soles. Background Art

[0002] Compression molding is a common and critical process in shoe sole manufacturing. It applies pressure to a heated, softened material, shaping it into the desired sole structure within a mold. This process is widely used in the production of various shoe soles due to its high molding efficiency and high product density. However, compression molding is highly dependent on molding conditions, particularly temperature and pressure, which have a direct impact on molding quality.

[0003] Most existing sole compression molding equipment uses preset temperature and pressure parameters for compression molding, lacking real-time monitoring and adjustment of the actual internal compression molding environment. Because the temperature and pressure during the compression molding process can be affected by environmental changes, equipment aging, or material differences, deviations between the compression molding conditions and actual requirements can occur. This can lead to problems such as uneven sole molding, large dimensional errors, and material burning, compromising product quality and production yield.

[0004] Therefore, there is an urgent need for a sole compression molding device that can detect the temperature and pressure inside the compression molding space in real time and dynamically adjust the compression molding process parameters according to the detection results, so as to improve the controllability of the compression molding process and the consistency of molding, and solve the problems of inaccurate control and lack of feedback adjustment capabilities in existing equipment, thereby meeting the increasingly high demand for quality stability and automation level in modern sole production.

DETAILED DESCRIPTION

[0055] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying 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 to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, unless there is a conflict, the embodiments of the present disclosure 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 accompanying drawings and in conjunction with the embodiments.

[0056] like Figure 1-Figure 2 As shown, in some embodiments of the present application, this embodiment provides a compression molding manufacturing device for soles, including: a compression molding part 100, a detection module and a control module.

[0057] Specifically, the compression molding part 100 is provided with a compression molding space therein, and the compression molding part 100 is configured to compression mold the material to be compression molded into a sole; the detection module is provided inside the compression molding space, and the detection module is configured to detect the internal temperature and internal pressure of the compression molding space; the control module is electrically connected to the detection module and the compression molding part 100 respectively, and the control module is configured to control the compression molding part 100 according to the internal temperature and internal pressure of the compression molding space.

[0058] It is understood that by providing a compression molding space within the compression molding section 100 for molding, this space is used to accommodate the sole material to be compression molded. Under the action of heat and pressure, the material is softened and filled into the mold cavity, ultimately forming the sole structure. The compression molding section 100 is the key execution unit for completing the physical molding process, and its heating and pressurizing capabilities directly affect the molding quality. Secondly, to ensure that the temperature and pressure are always maintained within a reasonable range during the compression molding process, the device is equipped with a detection module within the compression molding space. This detection module can obtain real-time temperature and pressure data in the compression molding space, reflecting the actual state of the current compression molding. Because the sensor is arranged internally, it can more accurately reflect the actual working conditions of the material under heat and pressure, providing a data basis for subsequent control. Finally, the control module in the device serves as the control core of the entire system. It is electrically connected to the detection module and the compression molding section 100 respectively. The control module receives the temperature and pressure data returned by the detection module in real time and compares it with the preset process parameters. Once abnormal conditions such as over-high temperature or insufficient pressure are detected, the control module can issue an adjustment instruction to dynamically adjust the heating power or pressure of the compression molding part 100 to achieve closed-loop control of the compression molding process.

[0059] By integrating real-time temperature and pressure monitoring and dynamic adjustment into the compression molding process, the present invention provides an intelligent, adaptive compression molding system. This technology, based on data-driven control logic, significantly improves the precision, stability, and consistency of sole molding, representing a significant improvement and upgrade to the traditional compression molding process.

[0060] Specifically, the compression molding part 100 includes: an upper shell 110 and a lower shell 120, each of which is provided with a compression molding groove 130 on the opposite side so that a compression molding space is formed when the upper shell 110 and the lower shell 120 are connected; a connecting shaft 140 is arranged on one side of the bottom of the upper shell 110, one end of the connecting shaft 140 is connected to the upper shell 110, and the other end of the connecting shaft 140 is connected to the lower shell 120; at least two groups of separation grooves 150 are provided, and the two groups of separation grooves 150 are respectively opened on the corresponding side of the upper shell 110 and the lower shell 120, and away from one end of the connecting shaft 140.

[0061] Specifically, the upper shell 110 is also configured with: at least two groups of connecting grooves 111, and the two groups of connecting grooves 111 are relatively arranged on both sides of the compression molding groove 130 along the setting direction of the upper shell 110; three groups of limiting grooves 112 are provided, and the three groups of limiting grooves 112 are respectively arranged on the surrounding sides of the compression molding groove 130; the heating module is arranged inside the compression molding groove 130, and the heating module is connected to the inner bottom surface of the compression molding groove 130, and the heating module is configured to heat the inner bottom surface of the compression molding groove 130.

[0062] Specifically, the lower shell 120 is also configured with: a texture cutting protrusion 121 is arranged inside the compression molding groove 130, and the texture cutting protrusion 121 is configured to perform texture cutting on the material to be compression molded according to a preset texture; at least two groups of connecting blocks 123 are arranged, and the two groups of connecting blocks 123 are arranged on both sides of the compression molding groove 130 relative to each other along the setting direction of the lower shell 120, and the connecting blocks 123 are arranged corresponding to the connecting groove 111; at least three groups of limiting columns 122 are arranged, and the limiting columns 122 are respectively arranged on the peripheral sides of the compression molding groove 130, and the limiting columns 122 are arranged corresponding to the limiting groove 112.

[0063] It can be understood that through structural optimization, the sole compression molding device has achieved improvements in molding accuracy, assembly stability, and functional diversity. Its compression molding unit 100 is composed of an upper shell 110 and a lower shell 120, each of which is provided with a compression molding groove 130 on opposite sides. When the upper shell 110 and the lower shell 120 are closed and connected, the two compression molding grooves 130 cooperate to form a closed compression molding space, accommodating and defining the position of the material to be compression molded, providing a basic molding environment for subsequent compression molding operations. Secondly, to achieve the hinged closure structure of the upper and lower shells 120, the device is provided with a connecting shaft 140 at the bottom of the upper shell 110. One end of this shaft is connected to the upper shell 110, and the other end is connected to the lower shell 120, acting as a rotating shaft, allowing the upper shell 110 to be opened and closed around the connecting shaft 140. At the same time, to ensure stable positioning and separation after the shells are closed, at least two sets of separation grooves 150 are designed, each located on the side away from the connecting shaft 140, so that when the shells are opened, they provide a force application point, facilitating the operator to disassemble the mold. In addition, in the structure of the upper shell 110, at least two groups of connecting grooves 111 are provided, which are located on both sides of the compression molding groove 130, and are used to engage with the connecting blocks 123 on the lower shell 120, so as to achieve a reliable connection between the shells. In addition, three groups of limiting grooves 112 are provided on the circumference of the upper shell 110, which are used to cooperate with the limiting columns 122 on the lower shell 120 for precise positioning and limiting, to prevent dislocation or displacement during the compression molding process, and to enhance the stability of the structure. At the same time, in order to meet the requirements of material thermal processing, a heating module is also configured inside the compression molding groove 130 of the upper shell 110. The module is directly connected to the inner bottom surface of the compression molding groove 130, which can quickly heat the mold surface and perform thermal softening treatment on the material to be compression molded, ensuring that the material can smoothly fill the mold cavity and be compacted and formed in a heated state. Finally, a texture cutting protrusion 121 is provided inside the compression molding groove 130 of the lower shell 120. This structure presents a preset texture pattern according to the design requirements of the sole. During the compression molding process, the bump applies local molding pressure to the softened material, thereby forming a specific anti-slip texture or decorative pattern on the sole surface, improving the product's functionality and appearance consistency.

[0064] Specifically, the detection module includes a temperature detection unit and a pressure detection unit. The temperature detection unit is located inside the compression molding tank 130 and is configured to detect the real-time temperature of the material to be compression molded. The pressure detection unit is located at the bottom of the compression molding tank 130 and is configured to detect the real-time pressure of the material to be compression molded.

[0065] Specifically, the control module includes: an acquisition unit electrically connected to the temperature detection unit and the pressure detection unit respectively, and the acquisition unit is configured to acquire the real-time temperature and real-time pressure of the material to be compressed; an analysis unit electrically connected to the acquisition unit, and the analysis unit is configured to determine whether to start the heating module based on the real-time temperature of the material to be compressed, and determine the heating temperature of the heating module based on the real-time temperature and real-time pressure of the material to be compressed; a central control unit electrically connected to the analysis unit and the heating module respectively, and when the analysis unit determines to start the heating module, the central control unit is configured to generate a control instruction based on the heating temperature determined by the analysis unit, and send the control instruction to the heating module.

[0066] It can be understood that by introducing a real-time detection and intelligent control mechanism of the dual parameters of temperature and pressure in the compression molding manufacturing device, precise control of the compression molding process is achieved. Its detection module includes a temperature detection unit and a pressure detection unit, wherein the temperature detection unit is arranged inside the compression molding tank 130, and can monitor the current temperature of the material to be compression molded during the compression molding process in real time; the pressure detection unit is arranged at the inner bottom of the compression molding tank 130, and can obtain the actual pressure value applied to the material to be compression molded. This dual detection structure ensures a comprehensive grasp of the hot-pressure state of the material and is the basis for subsequent intelligent control. Secondly, the control module coordinated with the detection module includes an acquisition unit, an analysis unit and a central control unit. The acquisition unit is electrically connected to the temperature detection unit and the pressure detection unit respectively, and is responsible for real-time acquisition of temperature and pressure data from the compression molding tank 130. These real-time data will be sent to the analysis unit for judgment and processing. Specifically, the analysis unit processes the collected temperature data to determine whether the current material meets the conditions for heating; if the temperature does not meet the standard, the analysis unit determines that the heating module needs to be started, and further combines the real-time temperature and pressure information to calculate the optimal heating temperature required by the heating module. This analysis logic enables the device to adaptively adjust the heat input according to the actual situation under different material types or environmental conditions, thereby improving the consistency and energy efficiency of compression molding. Subsequently, the central control unit receives the processing results from the analysis unit as the instruction issuance core of the entire control process. When the analysis unit determines that heating is required, the central control unit generates a control instruction based on the heating temperature determined by the analysis, and sends the instruction to the heating module to make it work according to the specified parameters. Through this closed control path, the full process control of "real-time detection-intelligent judgment-precise execution" is realized, ensuring that the temperature and pressure are always in the optimal state during the compression molding process.

[0067] Specifically, when the analysis unit determines whether to start the heating module based on the real-time temperature of the material to be pressed, it includes: the analysis unit is also configured to determine whether to start the heating module based on the relationship between the real-time temperature of the material to be pressed and the preset temperature configured by the analysis unit: when the real-time temperature is lower than or equal to the preset temperature, the analysis unit determines to start the heating module; when the real-time temperature is higher than the preset temperature, the analysis unit determines not to start the heating module.

[0068] Specifically, when the analysis unit determines the heating temperature of the heating module based on the real-time temperature and real-time pressure of the material to be molded, it includes: the analysis unit is also configured to obtain the temperature difference between the real-time temperature and the preset temperature, and determine the adjustment coefficient based on the relationship between the temperature difference and the first preset temperature difference and the second preset temperature difference pre-configured by the analysis unit: when the temperature difference is lower than the first preset temperature difference, the analysis unit determines the adjustment coefficient to be L1; when the temperature difference is higher than or equal to the first preset temperature difference, and the temperature difference is lower than the second preset temperature difference, the analysis unit determines the adjustment coefficient to be L2; when the temperature difference is higher than or equal to the second preset temperature difference, the analysis unit determines the adjustment coefficient to be L3; wherein the first preset temperature difference is lower than the second preset analysis difference, 1<L1<L2<L3; the analysis unit is also configured to obtain the preset heating temperature corresponding to the preset temperature, and determine the heating temperature of the heating module based on the relationship between the preset heating temperature and the adjustment coefficient.

[0069] Specifically, when the analysis unit determines that the adjustment coefficient is Li, i=1, 2, 3, it includes: the analysis unit is also configured to determine whether to correct the adjustment coefficient Li based on the relationship between the real-time pressure of the material to be pressed and the preset pressure configured by the analysis unit; when the real-time pressure is less than or equal to the preset pressure, the analysis unit determines not to correct the adjustment coefficient Li; when the real-time pressure is greater than the preset pressure, the analysis unit determines the correction coefficient based on the relationship between the real-time pressure and the preset pressure, and corrects the adjustment coefficient Li according to the correction coefficient.

[0070] Specifically, when the analysis unit determines the correction coefficient based on the relationship between the real-time pressure and the preset pressure, it includes: the analysis unit is also configured to obtain the pressure difference between the real-time pressure and the preset pressure, and determine the correction coefficient based on the relationship between the pressure difference and the first preset pressure difference and the second preset pressure difference configured by the analysis unit: when the pressure difference is less than or equal to the first preset pressure difference, the analysis unit determines the correction coefficient to be K1; when the pressure difference is greater than the first preset pressure difference, and the pressure difference is less than or equal to the second preset pressure difference, the analysis unit determines the correction coefficient to be K2; when the pressure difference is greater than the second preset pressure difference, the analysis unit determines the correction coefficient to be K3; wherein, the first preset pressure difference is less than the second preset pressure difference, and 1<K1<K2<K3.

[0071] It is understandable that the analysis unit, as the core intelligent component of the control module, has the ability to comprehensively analyze and judge the real-time temperature and pressure data during the compression molding process. It is based on a set of multi-condition hierarchical judgment and dynamic correction control logic to ensure that the heating module performs start-stop control and temperature adjustment in the optimal state, thereby realizing refined management of the compression molding environment. First, in the process of judging whether to start the heating module, the analysis unit will obtain the real-time temperature of the material to be compression molded and compare it with the preset temperature. When the real-time temperature is lower than or equal to the preset temperature, the analysis unit determines that the temperature in the compression molding tank 130 is insufficient and the heating module needs to be started; if the real-time temperature is higher than the preset temperature, the analysis unit determines that the current heat has met the demand and there is no need to start the heating module, thereby avoiding energy waste and overheating of the material. Secondly, when determining the required heating temperature of the heating module, the analysis unit will further calculate the temperature difference between the real-time temperature and the preset temperature. According to the position of the difference within the two preset temperature difference ranges, the analysis unit selects the corresponding adjustment coefficient Li (i = 1, 2, 3). The larger the temperature difference, the higher the corresponding adjustment coefficient, indicating that a higher heating intensity is required to quickly compensate for heat loss. This design implements a graded heating adjustment mechanism based on temperature error, improving the flexibility and efficiency of thermal control. After obtaining the adjustment coefficient, the analysis unit further analyzes the real-time pressure data of the material being molded. If the real-time pressure exceeds the preset pressure, it indicates that the material is under strong stress, and the heat conduction rate or material response may be abnormal, so the original adjustment coefficient needs to be corrected. The analysis unit divides the pressure difference into three intervals, each corresponding to a different correction coefficient Ki (i=1, 2, 3). The greater the pressure, the higher the correction coefficient, enhancing the temperature control response. When the real-time pressure is less than or equal to the preset pressure, no correction is required. Finally, the analysis unit multiplies the selected adjustment coefficient Li by the pressure correction coefficient Ki to obtain the final corrected heating coefficient. Combined with the preset heating temperature, the analysis unit calculates the actual target temperature for the heating module. This calculation process implements dual-dimensional temperature-pressure feedback control, ensuring high adaptability and regulation accuracy in the molding process under various operating conditions and disturbances.

[0072] It can be seen that by establishing a multi-level mapping relationship between temperature difference and pressure difference, combined with a hierarchical judgment mechanism of adjustment coefficient and correction coefficient, a dynamic, hierarchical and adaptive thermal control strategy is constructed, which not only significantly improves the compression molding efficiency and product quality, but also enhances the equipment's adaptability to complex working conditions. It is a breakthrough and optimization of the traditional fixed value control mode.

[0073] In the above-described embodiment, by integrating a detection module within the compression molding space, real-time data collection and feedback of the temperature and pressure during the compression molding process can be performed, thus overcoming the limitations of conventional sole compression molding equipment, which relies on preset parameters and lacks process perception capabilities. The detection module is arranged within the compression molding space, enabling closer monitoring of the actual molding area and more accurate data collection, thereby providing a reliable basis for subsequent intelligent control. Secondly, the control module is electrically connected to the detection module and the compression molding unit 100, and can dynamically adjust the heating or pressurization state of the compression molding unit 100 based on the detected temperature and pressure data, thereby achieving closed-loop control of the compression molding environment. This control method can effectively avoid parameter deviations caused by environmental fluctuations, material differences, or equipment aging, ensuring that the compression molding process is always within the optimal process window, thereby significantly improving molding quality. Finally, by providing a certain degree of intelligence and response speed in the control system, parameters can be adjusted in a timely manner during the compression molding process to avoid problems such as material overheating, insufficient compaction, or dimensional errors caused by response lag. This adaptive adjustment capability makes the compression molding process more adaptable to different raw materials and production environments, improving the stability and versatility of the manufacturing process.
