[0002] A mold base is the basic support structure of a mold, usually made of metal materials, and is used to fix and support each component of the mold. A non-standard mold base refers to a non-standard mold frame customized according to specific product requirements, which needs to be specially designed according to the special shape, size or production requirements of the product.

[0003] The existing non-standard mold bases have complex structures and many processing procedures, and errors are easily accumulated during the processing and manufacturing processes, affecting the final assembly accuracy. Moreover, since they are non-standard parts, each one needs to be individually positioned and processed during the processing, which results in low processing efficiency. In addition, the existing processing systems have deficiencies in the design of the clamping devices and cannot quickly and accurately fix the mold base to be processed, further affecting the processing efficiency and accuracy.

[0004] In view of the above problems, the existing technologies urgently need to be improved. Summary of the Invention

The finishing unit includes a processing device for performing processing actions and a clamping device for fixing the mold base to be processed. The clamping device is composed of a plurality of clamping components. Each clamping component includes a fixed substrate and a movable clamping plate. A reference positioning plate is arranged on the top surface of the fixed substrate. The movable clamping plate has at least degrees of freedom in the X and Y directions. The movable clamping plate can be controlled to approach the reference positioning plate and cooperate with the reference positioning plate to clamp and fix the workpiece to be processed.

Detailed implementation manners

[0018] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0019] It should be noted that in the description of this specification, the orientation or positional relationship indicated by terms such as "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. The X-direction and Y-direction in this embodiment are directions artificially defined for the convenience of understanding and description. As shown in the figure, this is understandable to those skilled in the art and will not be elaborated here.

[0020] As shown in the figure, an embodiment of the present invention specifically discloses a non-standard die carrier rapid and efficient processing system, including a finishing unit. The finishing unit includes a processing device for performing processing operations and a clamping device for fixing the die carrier to be processed. The clamping device is composed of a plurality of clamping components. Each clamping component includes a fixed base plate 1 and a movable clamping plate 3. On the top surface of the fixed base plate 1, there is a reference positioning plate 2. The movable clamping plate 3 has at least degrees of freedom in the X and Y directions. The movable clamping plate 3 can be controlled to approach the reference positioning plate 2 and cooperate with the reference positioning plate 2 to clamp and fix the workpiece to be processed. The processing device in this embodiment refers to a mechanical structure that performs milling, drilling or boring operations. Specifically, it can be realized by a spindle tool assembly driven by a servo motor, which is used to directly cut the workpiece. Its function is to reduce human operation errors through automated processing. The clamping device refers to a positioning mechanism composed of a plurality of clamping components. Specifically, it can be realized by a modular assembled fixture structure, which allows clamping of multiple workpieces or special-shaped workpieces at the same time. Its function is to reduce the processing waiting time through parallel clamping. The fixed base plate 1 refers to a rigid mounting platform with a reference positioning plate 2. Specifically, it can be realized by a steel platform with a surface ground treatment. Its function is to provide a fixed reference surface for the workpiece to eliminate cumulative errors. The reference positioning plate 2 refers to a positioning reference set on the fixed base plate 1. Its function is to establish the origin of the machining coordinate system to ensure the consistency of multi-process positioning. In this embodiment, the degrees of freedom in the X and Y directions refer to the position adjustment ability in the orthogonal directions in the machining plane. It can be realized by a combination structure of linear guides and servo motors. Its function is to realize the controllable expansion of the clamping range to adapt to the size change of the non-standard die carrier. Through the collaborative design of the multi-degree-of-freedom clamping structure and modular reference positioning, a clamping system that can adapt to the shape of non-standard workpieces is constructed. This design enables the movable clamping plate 3 to dynamically adjust the clamping position in the X / Y plane and cooperate with the fixed reference to form a reconfigurable clamping area, which not only maintains the machining accuracy of the reference positioning but also realizes rapid tool change and clamping. The combination of this spatial degree of freedom and rigid reference effectively solves the problem of repeated positioning caused by the inability of traditional fixed fixtures to adapt to the size change of non-standard parts, and at the same time reduces the probability of error accumulation by reducing the number of clamping times. The working principle of the clamping component in this embodiment is to use the reference positioning plate 2 on the fixed base plate 1 to provide a constant reference surface, combined with the movable clamping plate 3 that can move freely in the X-Y plane, to form an adaptive clamping mechanism. When it is necessary to clamp a non-standard die carrier, first place the workpiece on the reference positioning plate 2. Then the control system drives the movable clamping plate 3 to move in the X-Y plane to make it approach the workpiece. The movable clamping plate 3 cooperates with the reference positioning plate 2 to clamp the workpiece from two directions, realizing rapid and precise positioning. This design allows the clamping component to automatically adjust the clamping position according to the shape of the workpiece, which not only ensures the positioning accuracy during processing but also reduces the time for repeated disassembly and clamping. The multi-axial movement ability of the movable clamping plate 3 enables it to accurately match the clamping requirements of different specifications of workpieces.The adjustable clamping space formed by the reference positioning plate 2 and the movable clamping plate 3 can flexibly adapt to the special-shaped structure of the non-standard die set. This fundamentally solves the problem of frequent replacement of traditional fixed fixtures. At the same time, since the position of the reference positioning plate 2 is fixed, it is used as a reference for each clamping, avoiding the problem of reference loss caused by repeated disassembly and assembly in the traditional process. This design allows the clamping position to be adaptively adjusted according to the shape of the workpiece, ensuring the positioning accuracy during processing and reducing the time for repeated disassembly and clamping. Thus, the system significantly improves the processing efficiency of the non-standard die set, effectively reduces the processing error, and improves the final assembly accuracy.

[0021] In this embodiment, it further includes a cutting unit for cutting raw materials and a rough machining unit for rough machining the raw material to be processed. The cutting unit, the rough machining unit, and the finish machining unit are arranged in sequence according to the processing order. The cutting unit in this embodiment directly processes the raw material into the workpiece to be processed (in this embodiment, the workpiece to be processed is a general term for each component in the die set), solving the problem that the raw material cannot directly enter the finish machining unit. The rough machining unit performs preliminary shaping on the workpiece, reducing the processing load of the finish machining unit. The sequential arrangement of the three units forms a coherent processing line, avoiding frequent transfer of the workpiece between multiple independent devices and improving the overall processing efficiency. At the same time, through the pre-treatment of cutting and rough machining, the risk of cumulative error in the multi-process machining of the non-standard die set is reduced, ensuring the final processing accuracy. Specifically, the cutting unit is equipped with a laser cutting machine for cutting the raw material plate into the required initial shape and size; the laser cutting machine uses a high-power fiber laser and can achieve precise cutting of various metal materials; the rough machining unit is equipped with a CNC milling machine for preliminary shaping and surface rough machining of the cut workpiece; at the same time, the three processing units can be connected through an automated transmission system to achieve automatic transfer of the workpiece; the entire system can also be provided with a central control unit for unified scheduling and management to ensure the continuity and consistency of the processing flow, which can be understood by those skilled in the art and will not be elaborated here.

[0022] In this embodiment, both the reference positioning plate 2 and the movable clamping plate 3 are of an "L" - shaped structure. The reference positioning plate 2 is installed at a corner of the top surface of the fixed substrate 1. The reference positioning plate 2 and the movable clamping plate 3 clamp and fix the workpiece to be processed in a diagonal clamping manner. In this embodiment, both the reference positioning plate 2 and the movable clamping plate 3 are of an "L" - shaped structure. The inner side surfaces of the two sides of the "L" - shaped structure form mutually perpendicular positioning reference surfaces. When the movable clamping plate 3 moves to the target position, its "L" - shaped inner side surface and the "L" - shaped inner side surface of the reference positioning plate 2 form a symmetric clamping area, effectively increasing the clamping contact area. In this embodiment, the "L" - shaped reference positioning plate 2 and the movable clamping plate 3 provide multiple positioning reference surfaces, enhancing the accuracy of the initial positioning. The diagonal clamping method increases the clamping contact area, evenly distributes the clamping force, and avoids deformation or displacement of the workpiece caused by excessive local stress. In addition, the mechanical balance characteristics of diagonal clamping effectively suppress the vibration or offset of the workpiece during the processing, ensuring the stability of the workpiece during the processing. This design significantly improves the machining accuracy and consistency of the non - standard die carrier, adapts to the special shape and size requirements of the non - standard die carrier, and provides reliable clamping support for the rough machining and finish machining processes. During the clamping process, the movable clamping plate 3 moves towards the reference positioning plate 2 until the workpiece is firmly clamped by the inner side surfaces of the two. This diagonal clamping method makes the clamping force evenly distributed on two adjacent sides of the workpiece, increasing the contact area and improving the clamping stability.

[0023] In this embodiment, the clamping device further includes a sliding seat 8 installed on the bottom surface of the movable clamping plate 3. The fixed base plate 1 is provided with a plurality of sliding grooves 4. The movable clamping plate 3 is slidably installed in any one of the sliding grooves 4 through the sliding seat 8. The sliding seat 8 can be driven to slide along the corresponding sliding groove 4 to approach the reference positioning plate 2. In this embodiment, the clamping device further includes a driving slider 7 and a driving slide rail 6. The driving slide rail 6 is arranged along the X direction and is located at a position on the side of the fixed base plate 1 away from the reference positioning plate 2. In this embodiment, the driving slide rail 6 is arranged as two parallel ones. The two driving slide rails 6 are installed on the fixed base plate 1 through a mounting seat 9. The driving slider 7 is slidably installed on the driving slide rail 6. The sliding groove 4 extends along the Y direction. The driving slider 7 is provided with a limiting slideway. The limiting slideway slides in a follow-up manner and can be manipulated to align with any one of the sliding grooves 4. The sliding seat 8 can be driven to reciprocally slide between the limiting slideway of the driving slider 7 and the sliding groove 4 of the fixed base plate 1. In this embodiment, a guide rail I 5 is arranged in the sliding groove 4, and a guide rail II 13 is arranged in the limiting slideway. When the limiting slideway is aligned with the sliding groove 4, the guide rail I 5 and the guide rail II 13 are aligned with each other. Both the guide rail I 5 and the guide rail II 13 are provided with transmission teeth. When the guide rail I 5 and the guide rail II 13 are aligned with each other, the corresponding transmission teeth are engaged with each other. The sliding seat 8 is provided with a driving source and a driving tooth that is in transmission engagement with the transmission teeth. The driving source drives the transmission teeth to rotate so that the sliding seat 8 slides between the guide rail II 13 and the guide rail I 5 to approach or move away from the reference positioning plate 2. In this embodiment, the sliding connection between the sliding seat 8 and the sliding groove 4 is realized through the transmission cooperation of the guide rail and the driving gear 10. First, the driving slide rail 6 is arranged along the X direction, and the movable clamping plate 3 is installed on the driving slide rail 6 through the driving slider 7, so that the movable clamping plate 3 has the freedom degree in the X direction. The sliding of the driving slider 7 can be realized by the cooperation of a servo motor and a lead screw structure, or directly pushed by a pneumatic cylinder. When the driving slider 7 slides to a position where the limiting slideway is aligned with the target sliding groove 4, at this time, the transmission teeth of the guide rail I 5 and the guide rail II 13 form a continuous transmission path after being engaged. Then, the driving source drives the driving gear 10 to rotate, so that the sliding seat 8 drives the movable clamping plate 3 to approach the reference positioning plate 2 along the Y direction through the target sliding groove 4. This setting enables the movable clamping plate 3 to have the freedom degree in the Y direction. Thus, the movable clamping plate 3 obtains the compound motion ability in the X-Y plane, significantly improves the adaptability to workpieces of different sizes, and effectively improves the processing efficiency.

[0024] Moreover, when the limiting slideway is aligned with the sliding groove 4, the transmission teeth of the guide rail I 5 and the guide rail II 13 are engaged to form a continuous transmission path. The driving tooth is driven by the driving source to make the sliding seat 8 slide along the Y direction. After the slider moves to the target position along the X direction, the sliding seat 8 is switched into the limiting slideway. At this time, the sliding seat 8 can slide along the X direction to adapt to the change in the lateral dimension of the workpiece.

[0025] In this embodiment, a plurality of elastic members 12 are provided on the end face of the movable clamping plate 3 facing the workpiece to be machined, and a flexible sheath 11 is coated on the surface of the elastic members 12. The elastic members 12 are arranged on the end face of the movable clamping plate 3 and are distributed in an array. The elastic members 12 can be spiral springs or rubber pads. The flexible sheath 11 is made of silica gel or polyurethane material and covers the surface of the elastic members 12 to form a continuous contact surface. The compression stroke of the elastic members 12 is designed to be 5-10 mm to adapt to the undulation of the workpiece surface, and the Shore hardness range of the flexible sheath 11 is controlled within 40A-70A to balance the buffering performance and the supporting strength. When the slide 8 drives the movable clamping plate 3 to slide along the chute 4, the elastic members 12 disperse the clamping force through compression deformation, and the flexible sheath 11 fills the gap between the workpiece surface and the movable clamping plate 3 through its own deformation. During the clamping process, the elastic members 12 are elastically deformed under the pressure of the workpiece surface, converting the concentrated stress into a uniformly distributed load at multiple contact points, effectively avoiding the formation of indentations. The flexible sheath 11 is wrapped around the outer surface of the elastic members 12 to prevent the elastic members 12 from directly rubbing against the workpiece, and at the same time forms a surface contact with the workpiece surface through the ductility of the material itself. When the size of the workpiece changes, the independent compression characteristics of the elastic members 12 allow each contact point to adaptively adjust the height to maintain the uniformity of the contact pressure. During the movement of the slide 8 along the chute 4, the deformation amount of the elastic members 12 changes dynamically with the clamping distance, and the flexible sheath 11 continuously maintains the integrity of the contact surface. Through the cooperation of elastic support and flexible wrapping, high-stability clamping is achieved while avoiding damage to the workpiece surface, which is particularly suitable for the processing scenario of non-standard die sets with high surface precision requirements.

[0026] In this embodiment, the rough machining unit is also provided with a clamping device. Such a setting realizes the multi-degree-of-freedom positioning and stable clamping of the workpiece in the rough machining stage, eliminates the dimensional deviation caused by machining vibration. Among them, the unified structure of the reference positioning plate 2 and the movable clamping plate 3 ensures the same positioning reference in the rough machining and finish machining stages, reduces the error transfer between processes, the elastic contact structure of the movable clamping plate 3 avoids damage to the workpiece surface, the transmission gear meshing mechanism of the slide rail and the chute 4 improves the positioning accuracy of the clamping device, and the application of the clamping device in the rough machining unit reduces the equipment maintenance cost and improves the standardization degree of the operation process.

[0027] The present invention also discloses a method for quickly and efficiently machining a non-standard die set. This method is based on a non-standard die set quickly and efficiently machining system as described above, and specifically includes the following steps: S1. Raw material cutting; according to the design, the raw material is cut by the cutting unit to form a plurality of different workpieces to be machined; S2. First rough machining; the plurality of different workpieces to be machined are divided into multiple groups according to the thickness. After the workpieces to be machined with the same thickness are clamped and fixed by the same clamping device, rough machining of the top surface and the bottom surface is performed; S3. Second rough machining: Classify the workpieces after the first rough machining in step S2 into multiple groups based on their areas. Then stack and fix the workpieces with the same area, and perform rough machining on the sides. In the manufacturing process of non-standard die sets, the thickness, area, and structure of different workpieces vary greatly. If the traditional single-positioning machining method is directly used, it will lead to low efficiency of repeated clamping and positioning, and it is difficult to avoid error accumulation during the rough machining stage due to the lack of reasonable classification and batch processing, which will affect the precision of finish machining. Therefore, in this embodiment, rough machining of the top and bottom surfaces is completed based on thickness classification, and rough machining of the sides is completed by stacking and classifying based on area. Thickness grouping makes the clamping parameters unified, and only one positioning of the clamping device is required to complete the rough machining of the top and bottom surfaces, and the machining time can be shortened by 40%. Subsequently, the workpieces classified by area form a combination through stacking and fixing. When machining the sides, the tool makes one pass along the stacking direction to complete the machining of multiple workpieces, and the side milling efficiency is effectively increased by at least 3 times. Moreover, by unifying the reference plane through thickness classification, the flatness error of the rough machining of the top and bottom surfaces can be effectively controlled. Using the stacking structure for side machining can also effectively suppress the contour deviation caused by cutting vibration.

[0028] S4. Finish machining: Fix the workpieces that have completed rough machining in step S3 simultaneously through the clamping device, and then send them into the finish machining unit. Then, perform drilling machining and surface milling machining in sequence according to the design.

[0029] In this embodiment, step S4 further includes: S41. Drilling machining: First, according to the design, use the diameter of the smallest hole as the machining diameter for the first drilling machining to machine all holes and channels (including but not limited to guide pillar holes, cooling water channels, etc.). Then, in the order of increasing diameter, perform reaming processing on the corresponding holes and channels in sequence until all holes and channels reach the corresponding diameters. S42. Surface milling machining: Perform surface cutting and boring on the workpieces that have completed drilling machining to make each joint surface meet the design requirements.

[0030] In this embodiment, the finish machining stage adopts the sequence of drilling first and then milling, which avoids the deformation out-of-tolerance caused by stress release of thin-walled structural parts. During drilling, through the reaming steps from small to large, first, the machining accuracy of the holes or channels is improved, and second, the tool change time is reduced and the efficiency is increased. In this embodiment, the milling of the surface adopts cross-path cutting, and the cutting amount per layer is controlled at 0.1 mm, and the surface roughness can reach Ra1.6 μm. By combining stage-by-stage classification machining and batch processing, the number of clamping times is significantly reduced, the cumulative amount of rough machining errors is significantly decreased, and the qualified rate of finish machining is effectively improved.

[0031] As described above, it is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to form equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the technical solution content of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
