Abstract
Description
Technical Field
[0001] This utility model relates to a mold, specifically a punching mold. Background Technology
[0002] In the processing of metal sheets, array punching is required. Since the molds are usually fixed and lack the ability to adjust the position of the metal sheet, the number of punches in the mold must match the number of holes to be punched, increasing mold costs. Furthermore, even a slight change in the number of holes to be punched necessitates mold replacement, which is time-consuming and labor-intensive. If the positions of the punches and the product could be adjusted, these problems would be solved.
[0003] Since the position of the punch in the mold is fixed, and it is difficult to install an adjustment mechanism in the mold to adjust the position of the punch, the only option is to adjust the position of the product in the mold. However, molds usually have an upper mold and a lower mold. During the opening and closing process, manually adjusting the position of the product is relatively dangerous and has low adjustment accuracy.
[0004] Therefore, the technical problem that this application needs to solve is: how to effectively adjust the product position in the mold. Utility Model Content

Detailed Implementation
[0033] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.
[0034] like Figures 1 to 6 As shown, this embodiment proposes a punching die, comprising:
[0035] The lower mold assembly 11 has an upper surface for placing the product 12, and the product 12 has a positioning hole 13.
[0036] The positioning component 14 has a positioning part 41 on its top, which is used to be installed into the positioning hole 13. The lower mold component 11 has a clearance channel 15 for accommodating the positioning component 14.
[0037] The position adjustment component 16 is located below the positioning component 14, and the position adjustment component 16 has a moving part 17, which is fixedly installed at the lower end of the positioning component 14.
[0038] The upper die assembly 18 is provided with a punch assembly 19, the height of which is adjustable and used to punch the product 12.
[0039] The technical advantage of this solution is that it allows for the adjustment of the position of product 12, thereby facilitating effective punching of product 12.
[0040] In this solution, a positioning component 14 is installed by setting an avoidance channel 15 on the lower mold component 11. The positioning component 14 locks the position of the product 12. The moving part 17 of the position adjustment component 16 drives the positioning component 14 to move, thereby controlling the position of the product 12 and facilitating the full punching of the product 12.
[0041] Furthermore, the punch assembly 19 includes multiple punches, and the number of punches can also be a single punch or other numbers.
[0042] In this design, the positioning component 14 can move within the clearance channel 15, and can move along either the X-axis or the Y-axis. The opening size of the clearance channel 15 is determined based on the specific application scenario.
[0043] In this design, the distance between adjacent punches along the X-direction is b, and the distance between the centers of adjacent punches on product 12 is b / 2. A gap of b / 2 is provided in the X-direction of the clearance channel 15 for the movement of the punch assembly 19. The clearance channel 15 has a larger distance in the Y-direction to ensure the full operation of the punch assembly 19. This is not a limitation on the specific range of the punch assembly 19 in this design; other adjustments can be made according to actual needs.
[0044] As one implementation of this embodiment, the upper mold assembly 18 includes:
[0045] Fixed template assembly 20, which is used to be installed on the lifting drive mechanism;
[0046] The ejector assembly 21 is installed below the fixed template assembly 20 via an elastic element 22. The ejector assembly 21 has a through-hole 23, and the punch assembly 19 is disposed in the through-hole 23, with the upper end of the punch assembly 19 fixed to the fixed template assembly 20.
[0047] Among them, the elastic element 22 is a spring.
[0048] Furthermore, the lower end of the fixed template assembly 20 is provided with a guide rod 33, and the plate removal assembly 21 is provided with a guide hole 34, through which the guide rod 33 passes.
[0049] In this scheme, when the upper mold assembly 18 moves downward, the ejector assembly 21 first comes into pressure contact with the product 12 and stops, and then the fixed template assembly 20 continues to move downward. The punch assembly 19 installed on the fixed template assembly 20 moves downward, thereby punching the product 12.
[0050] The fixed template assembly 20 includes, from top to bottom, an upper mold base 24, an upper pad 25, and an upper clamping plate 26, which are fixedly connected to each other.
[0051] The stripping assembly 21 includes a solid plate 27 and a stripping plate 28 in a top-to-bottom order, and the solid plate 27 and the stripping plate 28 are fixedly connected.
[0052] As one embodiment of this invention, the position adjustment component 16 includes:
[0053] Mounting base 29 is fixedly connected to the lower mold assembly 11;
[0054] The displacement drive 30 is mounted on the mounting base 29 and has a moving part 17.
[0055] In one embodiment of this invention, the displacement drive 30 is a two-axis module. The two-axis module has an X-axis motion mechanism and a Y-axis motion mechanism. Specifically, both the X-axis and Y-axis motion mechanisms can be linear motors, rodless cylinders (as in the prior art), or any existing technology capable of achieving X-axis and Y-axis motion.
[0056] The X-axis motion mechanism can be directly mounted on the output end of the Y-axis motion mechanism, or the Y-axis motion mechanism can be mounted on the output end of the X-axis motion mechanism to achieve two-axis motion. Only the moving part 17 needs to be installed on the output end of the uppermost X-axis or Y-axis motion mechanism.
[0057] In addition, the displacement drive component 30 in this solution can also be replaced by a three-axis module in the prior art.
[0058] Furthermore, the moving part 17 is a moving plate.
[0059] Furthermore, the mounting base 29 includes a support plate 35 and a connecting post 36, with the support plate 35 fixed to the lower mold assembly 11 via the connecting post 36. A displacement drive component 30 is mounted on the support plate 35.
[0060] As one embodiment of this example, the positioning component 14 includes a first movable block 31 and a second movable block 32. The first movable block 31 is mounted on the moving part 17 via the second movable block 32, and a positioning part 41 is fixed on the first movable block 31.
[0061] The first active block 31 is located above the second active block 32.
[0062] In one embodiment of this invention, the positioning part 41 is a positioning pin.
[0063] Furthermore, the lower mold assembly 11 includes a lower template 37, a lower pad 38, and a lower mold base 39 in a top-to-bottom order, wherein the lower template 37, the lower pad 38, and the lower mold base 39 are fixedly connected in sequence.
[0064] The lower end of the lower mold base 39 is fixed with a lower pad 40, which serves as a support.
[0065] Furthermore, the punching die in this solution is installed in a punch press, which is not shown in the attached drawings and is existing technology. The punch press has a lifting drive mechanism to drive the fixed template assembly 20 to move vertically. Of course, the fixed template assembly 20 can also be lifted using other hydraulic or pneumatic drive components, which are located above the fixed template assembly 20 and used to drive the fixed template assembly 20 to lift.
[0066] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
