Description

Technical Field

[0001] The present invention relates to a technical field, and in particular, to a processing control method and system for a plastic mold. Background Art

[0002] In modern manufacturing, the use of plastic molds runs through the entire production process of plastic products. They are indispensable tools for producing high-quality plastic products, especially in industries such as automobiles, electronics, medical and consumer products. Plastic molds are usually made of high-performance metal materials, such as alloy steel or stainless steel, to ensure that they have sufficient hardness, wear resistance and corrosion resistance. The design and manufacture of these molds involve complex engineering calculations and precision machining technologies to achieve precise control of the flow, cooling and solidification processes of the plastic melt. With the growing market demand for personalized and customized products, existing plastic molds often need to be adjusted or slightly modified to adapt to new product designs or functional requirements. In order to improve the flow characteristics of the plastic melt, it may be necessary to redesign the mold's runner system, gate location or exhaust system. The temperature control of the mold is crucial to product quality. It may be necessary to add or re-layout cooling channels to optimize cooling efficiency. In order to improve the appearance quality or demolding performance of the molded product, it may be necessary to polish, plate or texture the mold surface. Due to design changes or dimensional errors, some dimensions of the mold may need to be modified. Fine-tuning: According to the changes in product functions, it may be necessary to add or modify functional components such as sliding blocks and ejectors in the mold. The processing accuracy of plastic molds is usually required to reach ±0.005mm or even higher, which places extremely high demands on processing equipment and operator skills. The modification of molds involves a variety of advanced processing technologies, such as high-speed CNC processing, EDM, wire cutting, etc. These technologies not only require operators to have professional knowledge and skills, but also require them to be able to understand and apply complex CAD / CAM software. The modification of molds includes not only actual mechanical processing, but also early design adjustments, process planning and later trial mold verification. This process may take weeks or even months. For companies that pursue rapid response to market changes, this is an unacceptable time cost. Since different mold manufacturers may adopt different design standards and manufacturing processes, even minor modifications may become complicated due to the lack of original design data. When a small modification of the plastic mold is required, many companies choose to re-customize the mold or send the mold back to the original manufacturer for modification, which undoubtedly increases the production cost and production cycle. Therefore, developing a method and system that can quickly and accurately control the processing of plastic molds on site is of great significance for improving production efficiency, reducing costs, and meeting the rapidly changing needs of the market.

Traditional mold processing methods usually require manual measurement and positioning, which is not only time-consuming but also prone to errors. The system in this application greatly shortens the preparation time before processing and improves the overall processing efficiency through automated 3D scanning and data processing. EDM technology can perform precision processing without being affected by the hardness of the material, which is particularly important for plastic molds made of difficult-to-process materials such as cemented carbide. Through precise 3D data guidance, EDM can accurately remove excess material and avoid material deformation or micro cracks that may occur in traditional processing. During the processing, environmental factors ( The system in this application strictly detects and controls the environmental conditions before processing, ensuring the environmental stability during the processing, thereby reducing the adverse effects of environmental changes on the processing accuracy.

At the same time, the combination of 3D scanning and EDM improves the repeatability and consistency of the processing process, so that each processing can meet the expected quality standards.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] As mentioned in the background technology, with the growing market demand for personalized and customized products, existing plastic molds often need to be adjusted or slightly modified to adapt to new product designs or functional requirements. In order to improve the flow characteristics of the plastic melt, it may be necessary to redesign the mold's runner system, gate position or exhaust system.

The processing accuracy of plastic molds is usually required to reach ±0.005mm or even higher, which places great demands on processing equipment and operator skills. In addition to the extremely high requirements, the modification of the mold involves a variety of advanced processing technologies, such as high-speed CNC machining, EDM, wire cutting, etc. These technologies require operators to have professional knowledge and skills, and also require them to understand and apply complex CAD / CAM software. The modification of the mold includes not only the actual machining, but also the preliminary design adjustment, process planning and later trial mold verification.

[0028] In order to improve the above problems, the present application proposes a plastic mold processing control method and system, which integrates advanced three-dimensional scanning technology and electrospark machining technology to provide an efficient, accurate and reliable solution for the precise machining of plastic molds. By performing three-dimensional scanning on the plastic mold, accurate three-dimensional data of the current state of the mold can be obtained.

[0029] First embodiment

[0030] See also Figure 1 As shown, a processing control method of a plastic mold according to an embodiment of the present application includes:

[0031] S1. Perform three-dimensional scanning on the plastic mold;

[0032] S2, obtaining three-dimensional data of the plastic mold and comparing it with the preset value of the plastic mold;

[0033] S3, the electric spark assembly cuts the plastic mold according to the preset value.

[0034] In some specific embodiments, in S1 , the top filling end of the plastic mold is placed upward, and the horizontality of the placement position of the plastic mold is detected.

[0035] It should be understood that by ensuring that the top filling end of the mold is facing upward, it can be ensured that the data obtained during the 3D scan accurately reflects the current state of the mold. If the mold is not placed properly, the scanned data may be biased, affecting the accuracy of subsequent processing. During the 3D scanning process, ensuring that the mold is placed horizontally can prevent mold deformation or internal structure damage caused by improper placement, especially when there are precise structures and components inside the mold. The correct placement posture can reduce the time required to adjust and reposition the mold, thereby improving the efficiency of the entire processing process. Levelness detection ensures the stability of the mold during the processing process, which is particularly critical for precision processing technologies such as EDM and helps In order to achieve high-quality processing results, any small error in the mold manufacturing and processing process may lead to a significant decrease in the quality of the final product. By strictly controlling the levelness in the initial steps, the accumulation of errors in the entire processing process can be reduced. Accurate placement and levelness detection ensure the authenticity and reliability of the 3D scanning data, and provide a solid foundation for subsequent data processing and processing. When the mold placement and positioning are standardized, it is easier to automate the processing process, reduce human intervention, and improve the stability and repeatability of production. Operators can quickly and accurately complete the mold setting according to clear placement requirements and levelness detection results, which improves the convenience of operation and the efficiency of processing preparation.

[0036] During the mold manufacturing and testing process, the instrument for measuring the horizontality of the mold can be a level, an electronic level, a coincident level, and a three-dimensional coordinate measuring machine; these instruments can ensure that the plastic mold is placed at an absolute level before three-dimensional scanning, which is crucial to the subsequent scanning accuracy. The cutting process performed by the EDM component according to the preset value requires high-precision positioning. The use of the level ensures the accuracy of the initial conditions of the processing. Through the method of optical double image overlap, the coincident level provides a clearer and more reliable reading, reduces the operator's reading error, and increases the reliability of the measurement process, thereby indirectly improving the final quality of the processing. When performing three-dimensional scanning, the three-dimensional coordinate measuring machine can provide high-precision spatial data, making the acquired three-dimensional data of the plastic mold more accurate. In this way, the comparative analysis against the preset value will be more accurate, reducing unnecessary iterative processes and improving the overall processing efficiency. By using precision measuring instruments such as a level, an electronic level, a coincident level and a three-dimensional coordinate measuring machine, the plastic mold processing control method and system in this application can improve the accuracy, efficiency and reliability of the processing, while optimizing product quality, saving time and cost, and enhancing the market competitiveness of the enterprise.

[0037] In some specific embodiments, the real-time temperature of the working environment of the plastic mold is detected in S1.

[0038] In some specific embodiments, the real-time humidity in the working environment of the plastic mold is detected in S1.

[0039] In some specific embodiments, when the plastic mold is placed at a horizontal position of 0°, the temperature of the working environment of the plastic mold is within 10°C to 40°C, and the humidity of the working environment of the plastic mold is within 20% to 80% RH, the plastic mold is scanned in three dimensions.

[0040] It should be understood that a horizontal degree of 0° ensures that the scan data will not cause errors due to placement angle problems. The appropriate temperature and humidity range prevents material expansion or contraction caused by excessively high or low temperatures, as well as material deformation or electrostatic interference caused by excessively high or low humidity. All of these factors may affect the scanning accuracy. Performing 3D scanning in a strictly controlled environment can ensure that the data obtained from each scan is consistent, which is crucial for subsequent data processing and mold correction. The consistency of the data directly affects the quality of the final product and reduces production differences caused by changes in environmental factors. When 3D scanning is performed in the best environment, the data obtained accurately reflects the true state of the mold and reduces the need for corrections in later processing. This not only improves processing efficiency, but also saves manufacturing costs. Controlling environmental conditions and performing scanning in the best state can minimize rescanning or adjustments due to environmental discomfort, thereby improving overall production efficiency.

[0041] In some specific embodiments, in S2, standard parameters of the plastic mold are pre-imported into the computer, and according to the actual production situation of the plastic mold, the standard parameters of the plastic mold are modified to obtain preset values ​​of the plastic mold.

[0042] It should be understood that through precise preset values, high precision can be ensured during the mold processing process, because the processing parameters are customized according to the actual production and needs of the mold, which directly improves the quality of mold manufacturing and reduces the occurrence of errors. Using preset values ​​to guide processing can reduce the number of trial and error and avoid unnecessary iterations, thereby optimizing the production process and reducing the waste of time and resources. The use of preset values ​​makes the processing process more standardized and automated, reducing the need for manual intervention, thereby improving overall production efficiency. The certainty of preset values ​​ensures that each processing can be carried out according to the established parameters, increases the stability and reliability of the production process, and reduces product inconsistency problems caused by operational deviations. It can correct parameters according to the actual production situation of the plastic mold, so that the processing system can flexibly adapt to different production needs and changes, enhancing the adaptability and flexibility of the system. Accurate preset values ​​help reduce material waste during processing because it reduces the mold scrap rate due to processing errors. By reducing waste, improving efficiency and reducing labor costs, the use of preset values ​​can directly reduce production costs and improve the economic benefits of the enterprise.

[0043] Second embodiment

[0044] A plastic mold processing control system according to an embodiment of the present application includes:

[0045] A scanning module, which is rotatably disposed above the plastic mold and is used to scan the entire plastic mold;

[0046] The cutting module includes a plurality of electric spark components, and the electric spark components are used to cut the plastic mold.

[0047] In some specific embodiments, the scanning module is electrically connected to the computer, and the scanning module is a three-dimensional scanner.

[0048] In some specific embodiments, the electric spark assembly is electrically connected to a computer, and the electric spark assembly cuts the plastic mold according to preset values ​​of the plastic mold.

[0049] In some specific embodiments, a temperature control module is further included, and the temperature control module is used to control the temperature of the plastic mold within the range of 10°C to 40°C.

[0050] It should be understood that the material properties of plastic molds are greatly affected by temperature. The appropriate temperature range can maintain the stability of material properties, prevent material deformation caused by excessive temperature or embrittlement caused by too low temperature, thereby ensuring the dimensional accuracy and service life of the mold. During the 3D scanning process, temperature control can reduce thermal expansion or contraction caused by temperature difference, ensure the accuracy of scanning data, and avoid errors caused by data deviation in subsequent processing. Temperature control not only affects the mold material, but also affects the performance of processing and scanning equipment. The appropriate temperature can maintain the stability and reliability of equipment operation and reduce the failure rate. By accurately controlling the temperature, energy waste caused by excessive heating or cooling can be avoided, efficient use of energy can be achieved, production costs can be reduced, and a suitable working environment can be provided for operators. It can improve work comfort and efficiency and reduce erroneous operations caused by environmental discomfort. Temperature consistency is one of the key factors to ensure product quality consistency. Through the temperature control module, the conditions of each production cycle can be ensured to be consistent, so as to produce products with consistent quality. Improper temperature control is a common cause of product size deviation and quality problems. Through precise temperature control, rework and scrap rates can be reduced and production efficiency can be improved.
