Description
Technical Field
[0001] This utility model relates to the field of molding die technology, and in particular to a molding die for a service bracket reinforcement plate. Background Technology
[0002] Service bracket reinforcement plates are typically made from metal sheets through multiple bending processes. The final structure includes a base plate, vertical edges formed by multiple bends on both sides of the base plate, and horizontal edges. The second horizontal edge needs to be flattened from an inclined state in the final process. In the existing technology, when locally flattening such complex three-dimensional bent blanks, the mold often fails to provide sufficient overall support and positioning for the blank. This causes the already formed first vertical edge, first horizontal edge, and second vertical edge to twist or deform during the stamping process, making it difficult to ensure the structural accuracy and shape stability of other formed parts of the workpiece while flattening the second horizontal edge.
[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model discloses a method to solve the problem that insufficient support and positioning of the die for the blank leads to twisting or deformation of the first vertical edge, the first horizontal edge, and the second vertical edge during the stamping process, making it difficult to ensure the structural accuracy and shape stability of other formed parts of the workpiece while flattening the second horizontal edge.
[0005] The technical solution adopted in this utility model is as follows: A service bracket reinforcement plate forming mold, characterized in that it is used for a service bracket reinforcement plate blank, wherein the middle part of the service bracket reinforcement plate blank is a base plate, the two sides of the base plate are bent vertically upward to form a first vertical edge, the first vertical edge is bent horizontally outward to form a first horizontal edge, the first horizontal edge is bent vertically upward to form a second vertical edge, the second vertical edge is bent horizontally inward to form a second horizontal edge, and the second horizontal edge is in an inwardly inclined upward state after the previous process; the service bracket reinforcement plate forming mold includes: The pressing molding module includes a lower module and an upper module. The top of the lower module has a placement groove for accommodating and positioning the base plate. The upper module includes a bonding block and two pressing blocks located on both sides of the bonding block. The bottom end of the bonding block matches the groove formed by the base plate and the two first vertical edges. The inner side of the bottom end of the pressing block has a pressing groove. The inner side wall and top wall of the pressing groove and the top of the side edge of the lower module form a cavity that matches the structure formed by the first horizontal edge, the second vertical edge and the second horizontal edge when the mold is closed.
[0006] A further technical solution is that the lower module is provided with limiting blocks at both ends, the limiting blocks protruding from the bottom plane of the placement groove to restrict the movement of the service bracket reinforcing plate blank.
[0007] A further technical solution is that the front and rear ends of the bonding block are provided with relief grooves that match the position of the limiting block, and the limiting block extends into the relief groove when the mold is closed.
[0008] A further technical solution is that the service bracket reinforcing plate forming mold further includes an upper mold base and a lower mold base, the upper module is disposed on the upper mold base, and the lower module is disposed on the lower mold base.
[0009] A further technical solution is that a guide member is provided between the upper mold base and the lower mold base. The guide member includes a guide post fixed on the upper mold base and a guide sleeve fixed on the lower mold base, and the guide post and the guide sleeve are slidably engaged.
[0010] A further technical solution is that the upper mold base and the lower mold base are respectively provided with a number of upper limit posts and a number of corresponding lower limit posts. When the mold is closed, the upper limit posts and the lower limit posts abut against each other, limiting the downward distance of the upper mold base relative to the lower mold base.
[0011] A further technical solution is that the service bracket reinforcing plate forming mold also includes a base plate shaping module, which is located on the side of the pressing forming module. The upper mold base is provided with an upper pressure column, and the lower mold base is provided with a lower pressure column corresponding to the position of the upper pressure column. When the mold is closed, the upper pressure column and the lower pressure column work together on the base plate of the service bracket reinforcing plate blank to level the base plate.
[0012] A further technical solution is that the base plate shaping module also includes a number of limiting rods disposed on the lower mold base, and the number of limiting rods limits the position of the service bracket reinforcing plate blank during the leveling process.
[0013] The beneficial effects of this utility model embodiment are as follows: (i) A service bracket reinforcement plate forming mold for service bracket reinforcement plate blanks. By setting a fitting block that precisely matches the contour of the bottom groove of the blank, the blank is accurately positioned and effectively supported in the width and height directions during the mold closing process. At the same time, the cavity formed by the pressing block and the side of the lower module forms a cavity that contains and constrains the side composite structure composed of the first horizontal edge, the second vertical edge and the inclined second horizontal edge during mold closing. The synergistic effect offsets the internal stress generated during the flattening of the second horizontal edge. While completing the flattening process of the second horizontal edge, it avoids unexpected twisting, deformation or displacement of other formed parts of the blank such as the first vertical edge, the first horizontal edge and the second vertical edge, ensuring the final overall dimensional accuracy and shape stability of the workpiece, and significantly improving the consistency and reliability of the product forming quality.
[0014] (ii) Furthermore, the service bracket reinforcing plate forming mold also includes a base plate shaping module, which is located on the side of the pressing and forming module. The upper mold base is provided with an upper pressure column, and the lower mold base is provided with a lower pressure column corresponding to the position of the upper pressure column. When the mold is closed, the upper and lower pressure columns work together on the base plate of the service bracket reinforcing plate blank to level the base plate. For example, the base plate shaping module also includes several limiting rods located on the lower mold base, which limit the position of the service bracket reinforcing plate blank during the leveling process. The coordinated action of the upper and lower pressure columns achieves precise leveling of the blank base plate, ensuring the thickness accuracy of the base plate after leveling and avoiding workpiece damage or mold overload caused by excessive pressing.

Detailed Implementation
[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0020] First embodiment: A service bracket reinforcement plate forming mold is used for a service bracket reinforcement plate blank 100. The service bracket reinforcement plate blank 100 has a base plate 110 in its middle part. The two sides of the base plate 110 are bent vertically upward to form a first vertical edge 120. The first vertical edge 120 is bent horizontally outward to form a first horizontal edge 130. The first horizontal edge 130 is bent vertically upward to form a second vertical edge 140. The second vertical edge 140 is bent horizontally inward to form a second horizontal edge 150. The service bracket reinforcement plate forming mold includes a pressing and forming module, which includes a lower module 201 and an upper module. 310, the lower module 201 has a placement groove at its top to accommodate and position the base plate 110; the upper module 310 includes a bonding block 311 and two pressing blocks 312 located on both sides of the bonding block 311; the bottom end of the bonding block 311 matches the groove formed by the base plate 110 and the two first vertical edges 120, and the inner side of the bottom end of the pressing block 312 has a pressing groove, the inner side wall and the top wall of the pressing groove and the top of the side of the lower module 201 form a cavity that matches the structure formed by the first horizontal edge 130, the second vertical edge 140 and the second horizontal edge 150 when the mold is closed. For example, the service bracket reinforcing plate forming mold also includes an upper mold base 300 and a lower mold base 200, the upper module 310 is disposed on the upper mold base 300, and the lower module 201 is disposed on the lower mold base 200. A guide member 400 is provided between the upper mold base 300 and the lower mold base 200. The guide member 400 includes a guide post 410 fixed on the upper mold base 300 and a guide sleeve 420 fixed on the lower mold base 200. The guide post 410 and the guide sleeve 420 are slidably engaged.
[0021] Furthermore, the lower module 201 is provided with limiting blocks 202 at both ends. The limiting blocks 202 protrude from the bottom plane of the placement groove, restricting the movement of the service bracket reinforcing plate blank 100. For example, the front and rear ends of the fitting block 311 are also provided with relief grooves 313 that match the limiting blocks 202. When the mold is closed, the limiting blocks 202 extend into the relief grooves 313. This structure restricts the front and rear displacement of the blank during the stamping process. At the same time, the relief grooves 313 form a precise fit with the limiting blocks 202 during the mold closing process, which not only provides auxiliary guidance for the mold closing action, but also avoids rigid collision between the upper module 310 and the limiting blocks 202, thereby protecting the mold while ensuring positioning accuracy.
[0022] Furthermore, the upper mold base 300 and the lower mold base 200 are respectively provided with a number of upper limit posts 320 and a number of corresponding lower limit posts 203. When the mold is closed, the upper limit posts 320 and the lower limit posts 203 abut against each other, limiting the downward distance of the upper mold base 300 relative to the lower mold base 200. This structure controls the minimum closing height of the mold by the rigid abutment of the ends of the upper limit posts 320 and the lower limit posts 203 at the end of the mold closing process, preventing excessive pressure loss caused by equipment stroke errors or blank thickness deviations, ensuring the forming stability of the flattening and leveling processes, and providing overload protection for the mold.
[0023] Furthermore, the service bracket reinforcing plate forming mold also includes a base plate shaping module, which is located on the side of the pressing and forming module. The upper mold base 300 is provided with an upper pressure column 330, and the lower mold base 200 is provided with a lower pressure column 204 corresponding to the position of the upper pressure column 330. When the mold is closed, the upper pressure column 330 and the lower pressure column 204 work together to flatten the base plate 110 of the service bracket reinforcing plate blank 100. For example, the base plate shaping module also includes several limiting rods 205 provided on the lower mold base 200, which limit the position of the service bracket reinforcing plate blank 100 during the flattening process. This structure achieves precise flattening of the blank base plate 110 through the synergistic action of the upper pressure column 330 and the lower pressure column 204, ensuring the thickness accuracy of the base plate 110 after flattening and avoiding workpiece damage or mold overload caused by excessive pressing.
[0024] In operation, this embodiment is as follows: The operator first places the blank from the previous process into the placement slot of the lower module 201 of the pressing and forming module, where it is positioned back and forth by the limiting block 202. Then, the upper mold base 300 is driven downward, and the upper module 310's fitting block 311 is precisely embedded into the bottom groove of the blank by the guide post 410 and guide sleeve 420. At the same time, the cavity formed by the pressing block 312 and the lower module 201 wraps and constrains the side composite structure and flattens the inclined second horizontal edge 150. After the pressing and forming is completed, the removed workpiece is transferred by the operator to the adjacent bottom plate shaping module and placed above the lower pressing post 204, which has been set with the limiting rod 205. When the upper mold base 300 is driven downward again, the upper pressing post 330 and the lower pressing post 204 perform collaborative leveling of the bottom plate 110. This design allows the operator to simultaneously load another blank into the pressing and forming module while one blank is being leveled in the bottom plate shaping module, thus realizing the parallel operation of the two functional modules.
[0025] In this embodiment, the final overall dimensional accuracy and shape stability of the workpiece are ensured, significantly improving the consistency and reliability of product molding quality.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
