Description

Technical Field

[0001] This utility model relates to stamping die technology, and in particular to a locking structure and stamping die that facilitates quick demolding. Background Technology

[0002] Stamping dies are commonly used forming equipment in the field of machining. A conventional eight-plate stamping die is assembled into two parts: an upper die and an lower die. The structure is as follows: the upper die consists of an upper die base, an upper backing plate, an upper clamping plate, a stop plate, and a stripper plate. The upper die base, the upper backing plate, and the upper clamping plate are fixedly connected by upper die base screws. The stop plate and the stripper plate are fixedly connected by stripper plate screws. The two parts are then locked together as one unit by equal-height sleeve screws. The lower die consists of a lower die plate, a lower backing plate, and a lower die base. The three are fixedly connected by lower die base screws.

[0003] In actual production, die punches are prone to wear or breakage due to long-term material cutting, requiring regular disassembly, maintenance, or replacement. However, traditional die-locking methods for stamping dies have many technical problems:

[0004] The mold disassembly operation is cumbersome and inefficient: Since the equal height sleeve screws are locked from the upper mold downwards, when the mold is set up on the machine, the screw holes above the upper mold will be covered by the machine, making it impossible to loosen the screws directly. It is necessary to first use large equipment such as forklifts and gantry cranes to disassemble the entire mold from the machine, replace the punch, and then re-set it on the machine and adjust the parameters. The whole process is time-consuming and labor-intensive, seriously occupies public equipment resources, and affects production efficiency.

[0005] The stripper plate stroke is inconvenient to change: If the production demand changes and the stripper plate stroke needs to be adjusted, the traditional structure requires the re-fabrication of the equal height sleeve, which has a long processing cycle and high cost.

[0006] Poor component versatility: Traditional equal-height sleeve screws are highly compatible with molds, but when old molds are scrapped, the related mold-locking components cannot be reused, resulting in a waste of resources;

[0007] Low template space utilization: A certain number of equal-height sleeve screws need to be arranged in the middle of the template to ensure locking strength, which occupies the effective usable area of ​​the template, resulting in the template size being forced to increase and the cost of mold opening rising.

[0008] In view of the shortcomings of the existing technology, there is an urgent need to design a new type of mold locking structure to solve the problems of cumbersome mold disassembly, inconvenient stroke adjustment, poor versatility and high cost of traditional stamping dies. Utility Model Content

[0009] The purpose of this utility model is to overcome the defects of the prior art and provide a mold locking structure and stamping die that facilitates quick mold disassembly, enabling the mold to directly replace the punch on the machine, simplifying the mold disassembly process, improving the flexibility of stroke adjustment, enhancing the versatility of components, and reducing production costs.

[0010] To achieve the above and other related objectives, the technical solution provided by this utility model is: a mold-locking structure that facilitates quick mold disassembly, including a C-shaped hook and a hook screw. The C-shaped hook includes a connecting part and hook part one and hook part two provided at both ends of the connecting part. The connecting part is provided with a through hole for the hook screw to pass through.

[0011] The preferred technical solution is that the perforation is a strip-shaped hole structure that extends toward both ends of the connecting part.

[0012] A stamping die, comprising the above-described clamping structure.

[0013] A preferred technical solution includes an upper mold, which is composed of an upper mold base, an upper pad, an upper clamping plate, a stop plate, and a stripper plate stacked on top of each other. The upper mold base, the upper pad, and the upper clamping plate are fixedly connected by upper mold base screws, and the stop plate and the stripper plate are fixedly connected by stripper plate screws. The upper clamping plate and the stop plate are fixed together by multiple sets of C-shaped hooks and multiple sets of hook screws. The C-shaped hooks are located at the edges of the upper clamping plate and the stop plate. One hook part is hooked to the top edge of the upper clamping plate, and the other hook part is hooked to the bottom edge of the stop plate. The hook screws are threaded to the side of the upper clamping plate through the through holes.

[0014] The preferred technical solution is that the side of the upper pad is provided with a clearance notch corresponding to the hook part.

[0015] The preferred technical solution is that the side of the stripping plate is provided with a clearance notch two corresponding to the hook part two.

[0016] A preferred technical solution is as follows: it further includes a lower mold, which is composed of a lower template, a lower pad, and a lower mold base stacked on top of each other, and the lower template, the lower pad, and the lower mold base are fixedly connected by screws on the lower mold base.

[0017] Compared with the prior art, the technical solution of this utility model has the following significant advantages:

[0018] This technology enables rapid mold disassembly while the mold is in place, significantly improving production efficiency. It abandons the traditional top-down locking structure with equal-height sleeve screws, instead using C-shaped hooks to lock the upper clamping plate and stop plate from the side of the mold plate. This avoids the problem of the upper locking structure being obstructed when the mold is mounted on the machine. When the punch needs to be replaced, there is no need to disassemble the entire mold from the machine. Simply loosen the side hook screws to separate the stop plate and upper clamping plate, allowing direct removal of the punch for maintenance or replacement. This saves time spent on transporting large equipment, re-erecting the mold, and adjusting parameters, significantly improving production continuity and efficiency.

[0019] The stripper plate stroke is flexible and reduces adjustment costs: Since the connecting part of the C-shaped hook has strip-shaped through holes extending to both ends, when it is necessary to change the stripper plate stroke, it is only necessary to loosen the hook screw, adjust the fixed position of the hook on the side, or perform simple grinding on the standard hook. There is no need to remake the equal height sleeve as in traditional technology, which greatly shortens the adjustment cycle and reduces processing costs.

[0020] High component versatility and resource cost savings: The C-shaped hook adopts a standardized design. When the old mold is scrapped, the hook can be disassembled and directly applied to the new mold. There is no need to customize the locking component for the new mold, which improves the component reuse rate and reduces the mold manufacturing cost.

[0021] Optimize template space layout and enhance structural load-bearing capacity: C-shaped hooks are installed at the edge of the template, eliminating the need to arrange a large number of equal-height sleeve screws in the middle of the template, effectively saving the effective usable area of ​​the template, which can indirectly reduce the overall size of the template and reduce the cost of mold opening materials; at the same time, the structural design of the hooks makes its load-bearing capacity much greater than that of traditional screws, and only four sets of hooks need to be set at the edge of the template to meet the locking strength requirements, further optimizing the stability of the mold structure.

[0022] In summary, this utility model, through its innovative C-shaped hook locking structure, specifically addresses the technical problems of cumbersome mold disassembly, inconvenient stroke adjustment, poor versatility, and high cost in traditional stamping dies. While ensuring the reliability of mold locking, it achieves multiple improvements in mold disassembly efficiency, adjustment flexibility, versatility, and cost control, demonstrating significant practical value and promotional significance.

Lock the upper clamping plate 33 and the stop plate 34 by using the C-shaped hook 1 and hook screw 2. Place the mold as a whole on the machine table for stamping production.

[0036] Punch replacement: When the punch is worn or broken, there is no need to disassemble the entire mold. Simply loosen the hook screw 2 on the side of the machine and remove the C-shaped hook 1 to separate the upper clamping plate 33 and the stop plate 34. Then loosen the punch fixing screw to complete the replacement or maintenance of the punch. After the replacement is completed, reinstall the C-shaped hook 1 and tighten the hook screw 2 to resume production.

[0037] Stripper plate stroke adjustment: When it is necessary to change the stroke of stripper plate 35, loosen hook screw 2, adjust the fixed position of C-shaped hook 1 on the side as required (using the adjustment margin of strip through hole 14), or perform a small amount of grinding on the connecting part 11 of C-shaped hook 1. After the adjustment is completed, tighten hook screw 2. There is no need to remake the locking part.

[0038] This embodiment completely solves the many drawbacks of the traditional equal-height sleeve screw mold locking method by using a C-shaped hook structure with side locking. While ensuring the stability of the mold structure and the stamping accuracy, it achieves the technical effects of rapid mold disassembly, flexible adjustment and resource saving, and has significant practical value.

[0039] Therefore, this utility model has the following advantages:
