Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to a step-by-step micro-shaping mold with adjustable drawing spacing. Background Technology

[0002] The mold technology that combines "step-by-step forming process" and "micro-shaping precision" is based on the core of achieving high-precision three-dimensional curved surface forming through multi-step adjustments. One of the processes of flexible mold technology is to form large / complex parts through segmented and multi-pass processing. It can suppress springback, optimize stress distribution, and achieve micron-level precision. It is commonly used in cold stamping progressive dies, medical devices and other fields.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent publication number: CN221456273U, published on 2024-08-02) discloses a high-density hydraulic step-by-step crucible forming mold, including: a central columnar punch, an annular punch, a double-acting hydraulic cylinder, a concave die, and a sliding displacement mechanism. The central columnar punch is fixedly connected to the sliding beam of a four-column hydraulic press. The double-acting hydraulic cylinders are evenly distributed along the outer circumference of the central columnar punch. One end of the double-acting hydraulic cylinder is fixedly connected to the central columnar punch, and the other end is fixedly connected to the annular punch. The punch is fixedly connected, with an annular punch sleeved on the central columnar punch. The top of the die is sleeved on the annular punch, and the bottom of the die can be slidably connected to the sliding displacement mechanism. This high-density hydraulic step-by-step crucible forming mold allows existing crucible manufacturers to replace the hydraulic press structure with a new type of crucible forming mold, producing crucible products with higher density, higher rigidity, and longer life than market expectations. It is suitable for various types of hydraulic presses and can be applied to crucible pressing molds of various specifications, seamlessly integrating with the automatic programmable control system of crucible hydraulic presses.

[0004] While the above design can solve the aforementioned problems, the mold docking process is not stable and the joint is not tight enough during processing. This results in poor finished product quality after demolding, reducing the efficiency of the equipment. Furthermore, when the equipment needs to adjust the joint, the existing design cannot perform precise fine adjustments, and the spacing is not accurately controlled. This design reduces the accuracy and stability of the equipment.

[0005] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0006] The purpose of this invention is to provide a step-by-step micro-shaping mold with adjustable drawing gap, in order to solve the problems mentioned in the background art, such as the unstable mold docking process and insufficient tightness at the docking point during processing, which results in poor finished product quality after demolding and reduced equipment efficiency. At the same time, when the equipment needs to adjust the docking point, the existing design cannot perform precise fine adjustment operations, and the control of the gap is not accurate. Such a design reduces the accuracy and stability of the equipment.

[0007] To achieve the above objectives, the solution of this utility model is: a step-by-step micro-shaping mold with adjustable drawing gap, including a bottom support plate, a limiting fitting frame installed on the upper surface of the bottom support plate, and a sliding stabilizing mechanism for laterally moving the buffer stabilizing rod installed inside the limiting fitting frame, the sliding stabilizing mechanism including a push-pull traction motor, the push-pull traction motor being fixedly installed on the upper surface of the bottom support plate, a nested stabilizing rod installed on the upper surface of the bottom support plate, and a nested adjustment mechanism for moving the first sliding mold installed outside the nested stabilizing rod.

[0008] Furthermore, the nested adjustment mechanism includes a hollow connecting plate, which is nested and slidably mounted on the top outer surface of the nested stabilizing rod. A compression spring is installed on the top outer surface of the nested stabilizing rod, and the end of the compression spring abuts against the outside of the hollow connecting plate.

[0009] Furthermore, rotating connecting rods are installed on the left and right sides of the hollow connecting plate, and the ends of the rotating connecting rods are rotatably connected to the outer surfaces of the first sliding mold and the second sliding mold. An internal extension rod is installed inside the rotating connecting rod, and a lower end docking block is installed on the upper surface of the bottom support plate.

[0010] Furthermore, a first sliding mold is installed on the outer surface of the output end of the push-pull traction motor, and the lower end of the first sliding mold is slidably installed inside the limiting and fitting frame. A second sliding mold is installed at the other end of the inside of the limiting and fitting frame, and the sliding trajectories of the first sliding mold and the second sliding mold correspond to each other.

[0011] Furthermore, the first sliding mold is equipped with two-sided extended racks on its left and right sides, and a central meshing gear is installed on the upper surface of the bottom support plate. The two-sided extended racks mesh with the central meshing gear, and a docking sliding frame is installed on the outer surface of the two-sided extended racks.

[0012] Furthermore, a back sliding plate is installed inside the docking sliding frame, and a buffer stabilizing rod is fixedly installed on the outer surface of the back sliding plate. Lower transmission racks are installed on the left and right corresponding sides of the back sliding plate, and the middle meshing gear meshes with the lower transmission rack. Moreover, the moving direction of the buffer stabilizing rod corresponds to the back of the second sliding mold.

[0013] Furthermore, the upper hollow position of the lower connecting block corresponds to the movement trajectory of the internal extension rod, and two sets of the lower connecting block, rotating connecting rod and internal extension rod are symmetrically installed about the center point of the hollow connecting plate. Moreover, the outer surface of the nested stabilizing rod contacts the inner surface of the hollow connecting plate to form a sliding structure.

[0014] With the above structure, the beneficial effects of this utility model, which relates to a step-by-step micro-shaping mold with adjustable drawing gap, compared with the prior art, are as follows: When the first sliding mold and the second sliding mold are docking, the extended racks on both sides will drive the lower transmission rack and the back sliding plate synchronously in opposite directions through the central meshing gear until the buffer stabilizing rod abuts against the back of the second sliding mold. This design makes the docking process of the mold more stable and tighter during processing, improves the finished product effect after demolding, and enhances the efficiency of the equipment. Furthermore, when it is necessary to adjust the position of the first sliding mold and the second sliding mold, the hollow connecting plate can be pulled inward or outward to rotate the connecting rod and drive it. At this time, the first sliding mold and the second sliding mold can be adjusted laterally along the inside of the docking sliding frame. This design enables the equipment to perform precise fine adjustment operations, and the control of the spacing is more accurate, which improves the accuracy and stability of the equipment. Furthermore, the movement of the hollow connecting plate remains stable due to the docking of the internal extension rod with the lower docking block, and the design of multiple hollow holes makes the use of the equipment more intelligent and stable.

[0017] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a step-by-step micro-shaping mold with adjustable drawing gap, including a bottom support plate 1, a limiting fitting frame 6 installed on the upper surface of the bottom support plate 1, and a sliding stabilizing mechanism for laterally moving the buffer stabilizing rod 11 is installed inside the limiting fitting frame 6. Figure 3 As shown, the sliding stabilizing mechanism includes a push-pull traction motor 2, which is fixedly installed on the upper surface of the bottom support plate 1. A nested stabilizing rod 12 is installed on the upper surface of the bottom support plate 1, and a nested adjustment mechanism for moving the first sliding mold 3 is installed on the outside of the nested stabilizing rod 12.

[0020] like Figure 2 , Figure 3 and Figure 4The technical solution shown addresses the problem that the mold assembly process is unstable and the joint is not tight enough during processing, resulting in poor finished product quality after demolding and reduced equipment efficiency. It discloses the following: a first sliding mold 3 is mounted on the outer surface of the output end of the push-pull traction motor 2, and the lower end of the first sliding mold 3 is slidably mounted inside the limiting and fitting frame 6. A second sliding mold 4 is mounted on the other end of the limiting and fitting frame 6, and the sliding trajectories of the first sliding mold 3 and the second sliding mold 4 correspond to each other. Extended racks 7 are mounted on both sides of the first sliding mold 3, and a central meshing gear 8 is mounted on the upper surface of the bottom support plate 1. Figure 4 As shown, the two extended racks 7 mesh with the central meshing gear 8, and the outer surface of the two extended racks 7 is equipped with a docking sliding frame 5. The inner surface of the docking sliding frame 5 is equipped with a back sliding plate 10, and the buffer stabilizing rod 11 is fixedly installed on the outer surface of the back sliding plate 10. The left and right sides of the back sliding plate 10 are equipped with lower transmission racks 9, and the central meshing gear 8 meshes with the lower transmission racks 9. Moreover, the moving direction of the buffer stabilizing rod 11 corresponds to the back of the second sliding mold 4.

[0021] When stability is required during the cold stamping progressive die process, the push-pull traction motor 2, fixedly installed above the bottom support plate 1, is directly activated to extend and push the die. The push-pull traction motor 2 then drives the first sliding die 3, fixedly installed on the outer surface of the output end, to slide synchronously along the extension direction. The sliding of the first sliding die 3 occurs within the limiting and fitting frame 6 fixedly installed above the bottom support plate 1. During the movement of the first sliding die 3, the two side extension racks 7, fixedly installed on both sides, are synchronously driven laterally. During the movement of the two side extension racks 7, they engage with the externally contacting central meshing gear 8, generating meshing motion. Driven by this meshing motion, the central meshing gear 8 continuously rotates in a circular motion. During the rotation of the central meshing gear 8, it again engages with the lower end transmission rack 9, which is in contact with the lower end. Figure 4 As shown, the lower transmission rack 9 will slide in the opposite direction along the upper part of the limiting fitting frame 6. Since the limiting fitting frame 6 is fixedly installed on the left and right sides of the back sliding plate 10, the back sliding plate 10 will be driven to perform limiting docking work along the inside of the docking sliding frame 5 fixed on the left and right sides of the first sliding mold 3. The movement of the back sliding plate 10 will synchronously drive the externally fixed buffer stabilizing rod 11 until the buffer stabilizing rod 11 abuts against the back of the second sliding mold 4. This design makes the docking of the first sliding mold 3 and the second sliding mold 4 more stable and efficient.

[0022] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown addresses the issue that existing designs cannot achieve precise fine-tuning when adjustments are needed at the docking points of the equipment, resulting in inaccurate spacing and reduced equipment precision and stability. The solution discloses a nested adjustment mechanism comprising a hollow connecting plate 14, which is nested and slidably mounted on the top outer surface of a nested stabilizing rod 12. A compression spring 16 is mounted on the top outer surface of the nested stabilizing rod 12, with its end abutting against the outside of the hollow connecting plate 14. Rotating connecting rods 15 are mounted on the left and right sides of the hollow connecting plate 14, with their ends rotatably connected to the outer surfaces of the first sliding mold 3 and the second sliding mold 4. Figure 5 As shown, an internal extension rod 17 is installed inside the rotating connecting rod 15, and a lower end docking block 13 is installed on the upper surface of the bottom support plate 1. The upper hollow position of the lower end docking block 13 corresponds to the movement trajectory of the internal extension rod 17. Two sets of lower end docking blocks 13, rotating connecting rod 15 and internal extension rod 17 are symmetrically installed about the center point of the hollow connecting plate 14. Moreover, the outer surface of the nested stabilizing rod 12 contacts the inner surface of the hollow connecting plate 14 to form a sliding structure.

[0023] When it is necessary to adjust the gap between the first sliding mold 3 and the second sliding mold 4, the hollow connecting plate 14 is directly fixed and slid along the upper end of the nested stabilizing rod 12 fixedly installed on the upper surface of the bottom support plate 1. During the movement of the hollow connecting plate 14, the rotating connecting rods 15 rotatably installed inside on its left and right sides will be driven to rotate synchronously. The ends of the rotating connecting rods 15 will gradually expand laterally as driven. Since the ends of the left and right sets of rotating connecting rods 15 are respectively fixedly installed on the sides of the first sliding mold 3 and the second sliding mold 4, as shown... Figure 6 As shown, the first sliding mold 3 and the second sliding mold 4 will expand laterally or slide accordingly as driven. During the movement of the rotating connecting rod 15, the internally rotating internal extension rod 17 will be driven synchronously, so that the internal extension rod 17 slides against the upper surface of the lower end docking block 13 fixedly installed above the bottom support plate 1. During the movement of the end of the internal extension rod 17, it will be nested with the hollow position opened above the lower end docking block 13. Since the internal extension rod 17 is radially extended, this design makes the adjustment design of the equipment more intelligent and precise.

[0024] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
