Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a mold structure with a square cylindrical forming and closing function. Background Technology

[0002] Given that current manufacturing processes for square products requiring tapered assembly mostly employ edge folding and rolling techniques for tapering, and sometimes spinning, rolling, or customized tapering equipment, and these processes are mostly used for cylindrical shapes, they are not very suitable for square cylindrical tapering. Traditional equipment for processing square cylindrical tapering is relatively complex, requiring multiple steps, and is not convenient for quickly forming square cylindrical taperings through stamping. Furthermore, when square cylindrical taperings are processed using traditional equipment, the part and the processed structure are not easy to separate and demold, resulting in the need to spend time or add steps to solve the separation problem, which is a waste of time and resources. When processing parts with taperings that are smaller at the top and larger at the bottom, separation and demolding are even more difficult.

[0003] To address the aforementioned issues, a mold structure with a square cylindrical forming and closing function is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a mold structure with a square cylindrical forming and closing function, which solves the problem that the traditional equipment for square cylindrical closing is relatively complicated in the background technology, and that the part and the processed structure are not easy to separate and demold when the square cylindrical closing is processed by the traditional equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mold structure with a square cylindrical forming and closing function, comprising a lower mold plate and an upper mold plate positioned directly above the lower mold plate. A stamping column is provided at the upper end of the upper mold plate. A stamping guide assembly is provided between the lower mold plate and the upper mold plate.

Four sets of shaping assemblies are provided, and multiple sets of driven assemblies are provided inside the lower end of the lower pressing block. The multiple sets of driven assemblies contact the four sets of shaping assemblies. The object to be stamped is placed inside the upper end of the lower mold plate. The stamping guide assembly reduces the distance between the upper and lower mold plates, and the lower pressing block stamps the object, forming a square structure. Then, through the stamping of the stamping column, the driven assemblies inside the lower pressing block push the four sets of shaping assemblies outwards, further compressing the square structure and causing deformation. This initially completes the square cylindrical forming and closing structure of the object. The lower pressing block rises, allowing the lower pressing block and the object to be demolded.

[0006] Furthermore, a recessed block is provided at the upper end of the lower template, and a stamping groove is provided inside the recessed block. The stamping groove is used to place the object to be stamped, and the recessed block is located directly below the lower pressing block.

[0011] Furthermore, the driven component includes a rotating shaft movably disposed inside the lower pressure block, a starting bar and a connecting post disposed on the outer side of the rotating shaft, the starting bar and the connecting post being on the same axis, a dovetail guide block disposed at one end of the connecting post, and the connecting post being rotatably connected to the dovetail guide block. The driven component also includes a fixing bar fixedly disposed inside the lower pressure block, with the starting bar located at the lower end of the descending plate.

[0012] Furthermore, the end of the fixing strip is provided with a through groove, and multiple sets of through grooves are provided. The lower end of the dovetail guide block is fitted into the inside of two adjacent sets of through grooves.

[0013] Furthermore, the shaping component includes a shaping arc strip fitted inside the fitting strip groove. The shaping arc strip is fitted inside the corresponding fitting strip groove. One end of the shaping arc strip is provided with a triangular block, and the triangular block is in contact with the dovetail guide block.

[0014] Furthermore, movable shafts are fixedly installed on both sides of the rotating shaft, and the two sets of movable shafts are movably connected to the inside of the lower pressure block. A connecting spring is installed on the outside of the movable shaft, one end of the connecting spring is fixedly connected to the side of the rotating shaft, and the other end of the connecting spring is fixedly connected to the inner wall of the lower pressure block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention provides a mold structure with a square cylindrical forming and closing function. This application places the object to be stamped inside the upper end of the lower template, and the stamping guide component reduces the distance between the upper and lower templates. The lower pressure block stamps the object to form a square structure. Then, through the stamping of the stamping column, the driven component inside the lower pressure block pushes the four sets of shaping components to expand outward, and squeezes the square structure of the object again to cause deformation. The square cylindrical forming and closing structure of the object is initially completed. The lower pressure block rises, allowing the lower pressure block and the object to be demolded. This solves the problem that the processing technology of square cylindrical closing is relatively complicated by traditional equipment, and that the part and the processed structure are not easy to separate and demold when the square cylindrical closing is processed by traditional equipment.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To address the technical problem that traditional equipment involves complex processing of square cylindrical openings, requiring multiple steps and making it inconvenient to quickly form square cylindrical openings using a stamping structure, such as... Figures 1-6 As shown, the following preferred technical solutions are provided:

[0028] A mold structure with a square cylindrical forming and closing function includes a lower mold plate 1 and an upper mold plate 2 positioned directly above the lower mold plate 1. A stamping column 3 is provided at the upper end of the upper mold plate 2. A stamping guide assembly 4 is positioned between the lower mold plate 1 and the upper mold plate 2. A lower pressing block 5 is provided at the lower end of the upper mold plate 2. A shaping assembly 6 is movably arranged on the outer side of the lower end of the lower pressing block 5. Four sets of shaping assemblies 6 are provided. Multiple sets of driven assemblies 7 are provided inside the lower end of the lower pressing block 5. The multiple sets of driven assemblies 7 interact with the four sets of shaping assemblies. When components 6 come into contact, the object to be stamped is placed inside the upper end of the lower template 1. The stamping guide component 4 reduces the distance between the upper template 2 and the lower template 1, and the lower pressing block 5 stamps the object to form a square structure. Then, through the stamping of the stamping column 3, the driven component 7 set inside the lower pressing block 5 pushes the four sets of shaping components 6 to expand outward, and squeezes the square structure of the object again to cause deformation. The square cylindrical forming and closing structure of the object is initially completed. The lower pressing block 5 rises, allowing the lower pressing block 5 and the object at this time to be demolded.

[0029] The lower template 1 has a recessed block 11 at its upper end, and a stamping groove 12 is formed inside the recessed block 11. The stamping groove 12 is used to place the object to be stamped. The recessed block 11 is located directly below the lower pressing block 5. The stamping guide assembly 4 includes a fixing post 41 set at the upper end of the lower template 1 and a stamping shrinking rod 42 set at the lower end of the upper template 2. There are four sets of fixing posts 41 and stamping shrinking rods 42. The four sets of fixing posts 41 and stamping shrinking rods 42 correspond to each other. The lower pressing block 5 includes a fitting strip groove 51 formed on the outer side of its lower end, and there are four sets of fitting strip grooves 51. The upper end of the lower pressure block 5 is provided with an upper groove 52, and a lowering plate 53 is fitted inside the upper groove 52. The upper template 2 includes a stamping block 21 and a fixing block 22 located directly below the stamping block 21. The stamping block 21 and the fixing block 22 have the same length and width. The stamping block 21 is connected to the stamping column 3. The lower end of the stamping block 21 is provided with an action block 211, and the action block 211 is fitted inside the fixing block 22. Spring guide posts 212 are provided at the four corners of the lower end of the action block 211. Four sets of spring guide posts 212 are provided. The other end of the spring guide posts 212 is located inside the lowering plate 53.

[0030] The driven assembly 7 includes a rotating shaft 72 movably disposed inside the lower pressure block 5. A starting bar 71 and a connecting post 73 are disposed on the outer side of the rotating shaft 72. The starting bar 71 and the connecting post 73 are on the same axis. One end of the connecting post 73 is provided with a dovetail guide block 75, and one end of the connecting post 73 is rotatably connected to the dovetail guide block 75. The driven assembly 7 also includes a fixing bar 74 fixedly disposed inside the lower pressure block 5. The starting bar 71 is located at the lower end of the lowering plate 53. The end of the fixing bar 74 has a through groove 741. Furthermore, multiple sets of through slots 741 are provided, and the lower end of the dovetail guide block 75 is fitted into the interior of two adjacent sets of through slots 741. The shaping component 6 includes a shaping arc strip 61 fitted into the interior of the fitting strip groove 51. The shaping arc strip 61 is fitted into the corresponding fitting strip groove 51. One end of the shaping arc strip 61 is provided with a triangular strip block 62, and the triangular strip block 62 is in contact with the dovetail guide block 75. The length of the fixing strip 74 is less than the length of the shaping arc strip 61, and one end of the fixing strip 74 is fitted into the interior of the shaping arc strip 61.

[0031] Specifically, the object to be shaped is placed inside the stamping groove 12. Under the action of the stamping retraction rod 42, the lower pressing block 5 and the shaping component 6 descend until they are fitted inside the stamping groove 12, at which point the part is stamped. When it is necessary to form a square cylindrical opening that is smaller at the top and larger at the bottom, the stamping block 21 and the actuating block 211 are lowered by driving the stamping column 3 until the spring guide column 212 is compressed to its limit. At this point, the lowering plate 53 descends along with the actuating block 211. The descent of the lowering plate 53 will be coordinated with multiple sets of... When the starting bar 71 contacts and is pressed down, the rotating shaft 72 rotates. Since one end of the rotating shaft 72 is rotatably connected to the dovetail guide block 75, the dovetail guide block 75 will exert a squeezing force on the triangular bar 62, thereby causing the shaping arc bar 61 to move outward of the pressing block 5 and perform extrusion deformation on the part. The two sets of through grooves 741 are set to provide guidance for the dovetail guide block 75, and the fixed bar 74 is partially embedded inside the shaping arc bar 61, which also provides a guiding effect for the shaping arc bar 61.

[0032] To address the issue of difficulty in separating and demolding the parts from the machined structure when producing square cylindrical shapes using traditional equipment, which necessitates time-consuming or additional steps to resolve the separation problem and is therefore a waste of time and resources, such as... Figures 6-8 As shown, the following preferred technical solutions are provided:

[0033] The shaping component 6 includes a shaping arc strip 61 fitted inside the fitting strip groove 51. The shaping arc strip 61 is fitted inside the corresponding fitting strip groove 51. One end of the shaping arc strip 61 is provided with a triangular block 62, and the triangular block 62 is in contact with the dovetail guide block 75. The length of the fixing strip 74 is less than the length of the shaping arc strip 61. One end of the fixing strip 74 is fitted inside the shaping arc strip 61. Movable shafts 721 are fixedly provided on both sides of the rotating shaft 72, and the two sets of movable shafts 721 are movably connected to the inside of the lower pressure block 5. A connecting spring 722 is provided on the outside of the movable shaft 721. One end of the connecting spring 722 is fixedly connected to the side of the rotating shaft 72, and the other end of the connecting spring 722 is fixedly connected to the inner wall of the lower pressure block 5. The four sets of shaping components 6 are replaced with four-corner arc components 8.

[0034] Specifically, when the rotating shaft 72 rotates in the forward direction, it compresses the connecting spring 722. After the initial stamping is completed, the stamping block 21 is raised by the stamping column 3, which causes the lowering plate 53 to rise. Under the elastic force of the connecting spring 722, the rotating shaft 72 rotates in the reverse direction, allowing the four sets of shaping arc strips 61 to re-fit into the fitting strip groove 51. At this time, the shaping component 6 no longer contacts the deformed part. Then, the stamping shrinkage rod 42 extends, and the lower pressure block 5 and the shaping component 6 can be separated from the part at this time. No additional machinery or steps are needed to complete the separation and demolding work. After the stamping is completed, the square cylinder of the part is initially closed. By replacing the shaping component 6 with the four-corner arc component 8, which is set to fit into the four corner positions of the lower pressure block 5, the four corners of the part are squeezed by the corresponding driven component 7 and the lowering plate 53. The secondary processing structure with the four-corner arc component 8 also has the function of facilitating demolding, thereby reducing the part processing time.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
