Description

Technical Field

[0001] The invention relates to the technical field of moulds, in particular to a mould for producing a metal C-shaped sealing ring with a cooling function. Background Art

[0002] Mold processing refers to the processing of forming and blanking tools. It also includes shearing dies and die-cutting dies. Usually, the mold consists of an upper die and a lower die. The steel plate is placed between the upper and lower dies. The material is formed under the action of a press. When the press is opened, a workpiece determined by the shape of the mold is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed by molds. Mold processing processes include: cutting dies, blanking dies, compound dies, extrusion dies, four-slide dies, progressive dies, stamping dies and die-cutting dies.

[0003] The inner side of the traditional metal C-shaped sealing ring is concave, and the existing metal C-shaped sealing ring processing mold is too complicated. It is inconvenient to put and take the material during the processing, which is not convenient for users to use. At the same time, during the processing of the blank, the blank is unevenly stressed, resulting in poor product quality. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A mold for producing a metal C-shaped sealing ring with a cooling function, comprising a fixed plate, a guide column fixedly connected to the top of the fixed plate, four guide columns, the four guide columns are evenly distributed at the top corners of the fixed plate, a top plate fixedly connected to the top of the guide column, and a hydraulic cylinder fixedly connected to the top of the top plate;

[0005] A moving assembly, the moving assembly is slidably connected to the guide column, and the moving assembly is fixedly connected to the output end of the hydraulic cylinder;

[0006] The fixed mold assembly is fixedly installed at the top middle of the fixed plate;

[0007] The movable mold assembly is fixedly installed at the top middle of the fixed plate, and the movable mold assembly is located inside the fixed mold assembly;

[0008] Among them, the movable mold assembly includes a fixed ring, which is fixedly installed in the middle of the top of the fixed plate. The outer side of the fixed ring is slidably connected with a fixed rod, and the end of the fixed rod is fixedly connected with a trapezoidal block. The fixed rod penetrates the fixed ring and extends to the inside of the fixed ring. The hydraulic cylinder drives the square plate to move downward, and the square plate drives the trapezoidal tube at the bottom to contact and squeeze the trapezoidal block. Under the action of the extrusion force, the trapezoidal block is forced to drive the arc-shaped part to move toward the direction of the fixed mold assembly through the fixed rod. The arc-shaped part contacts the annular blank and continues to move toward the direction of the C-shaped plate. Under the mutual extrusion between the C-shaped plate and the arc-shaped part, the middle part of the annular blank is squeezed into an inward concave structure. Multiple arc-shaped parts form a ring. At this time, the arc-shaped part applies forces in multiple directions to the inner wall of the annular blank, so that radial force and axial force The compression spring is arranged at one end of the fixing rod and the elastic properties of the compression spring are utilized, so that the arc-shaped part can automatically adjust the extrusion force on the blank according to the deformation of the metal blank. When the local deformation of the blank is large, the elastic support will increase the supporting force on the part accordingly, so that the pressure is more evenly distributed on the blank, thereby avoiding defects such as excessive thinning and cracking of the material caused by excessive local pressure, and improving the forming quality and dimensional accuracy of the C-shaped sealing ring. The end of the compression spring away from the trapezoidal block is fixedly connected to the inner wall of the fixing ring, and the end of the fixing rod away from the trapezoidal block is fixedly connected to the arc-shaped part.

[0009] Preferably, a cylinder is fixedly connected to the middle of the top of the fixed plate, the cylinder is located at the axis of the fixed ring, a fixed block is fixedly connected to the top of the cylinder, and the cylinder and the hydraulic cylinder are located on the same vertical line.

[0010] Preferably, there are multiple fixing rods, and the multiple fixing rods are evenly distributed with the fixing ring as the center, and the outer side of the fixing rod is fixedly connected with a protrusion, and the number of protrusions is multiple, and the multiple protrusions are evenly distributed with the fixing rod as the center, and the fixing rod is fixedly connected with an intermediate plate near the outer side of the arc-shaped member, and the outer side of the intermediate plate is rotatably connected with an extension plate. After the annular blank is placed, the hydraulic cylinder drives the square plate to move downward, and the square plate drives the positioning rod and the trapezoidal cylinder to move. Under the action of the mutual extrusion force between the hypotenuse of the trapezoidal cylinder and the hypotenuse of the trapezoidal block, the trapezoidal block drives the fixing rod to move in the direction close to the arc plate, so that the extension plate slides inside the through hole, and at this time, the extension plates on both sides of the fixing rod are used to press the annular blank. Extrusion in the vertical direction makes the middle of the annular blank located in the middle of the C-shaped plate, which helps to ensure the key dimensions of the C-shaped sealing ring, reduce dimensional deviation, and improve product consistency and interchangeability. At the same time, the middle alignment allows the materials on both sides to bend symmetrically around the arc-shaped part, avoiding problems such as inconsistent bending angles and different curvature radii due to uneven force on one side, and reducing surface wrinkles, scratches and other defects caused by uneven deformation, thereby obtaining a C-shaped sealing ring with a regular and uniform shape.

Under the action of the mutual extrusion force between the hypotenuse of the trapezoidal tube and the hypotenuse of the trapezoidal block, the arc plate moves toward the direction of the annular blank so that the arc plate contacts the annular blank, and the mutual repulsion between the magnetic block and the magnetic strip is used to make the outer surface of the arc plate fit tightly with the surface of the annular blank, thereby avoiding lateral sliding of the annular blank due to excessive mold gap or unstable positioning during processing, thereby reducing problems such as misalignment and dimensional deviation at both ends, the arc plate is located on the outer side of the circular tube, and the axis of the circular tube and the arc plate coincide, the end of the connecting rod away from the arc plate is fixedly connected to the magnetic block, the magnetic block is located inside the circular tube, and the inner wall of the circular tube close to the fixing rod is fixedly connected to the magnetic strip, and the magnetic properties of the magnetic strip and the magnetic block are the same.

Due to the sliding friction between the annular blank and the C-shaped plate and the arc plate, heat will be generated. Local overheating may cause uneven materials and defects in the concave part. By arranging multiple heat sinks on the outer side of the C-shaped plate, a heat dissipation effect is played, which can reduce the softening and oxidation of metal materials caused by local overheating, thereby improving the dimensional accuracy and surface quality of the C-shaped sealing ring. There are multiple heat sinks, and the heat sinks are evenly arranged on the heat sink.

At the same time, the fixed block enters the inside of the through groove, and extrusion is generated between the fixed block and the slider. The return spring is compressed and deformed by force. As the square plate continues to move downward, until the slider stops sliding, the hydraulic cylinder stops working and plays a role of limiting, thereby avoiding the problem of excessive stamping depth.

[0015] The present invention provides a mold for producing a metal C-shaped sealing ring with a cooling function. It has the following beneficial effects:

[0016] 1. The mold for producing the metal C-type sealing ring with cooling function forms a ring through multiple arc-shaped parts.

When the local deformation of the blank is large, the elastic support will correspondingly increase the supporting force on the part, so that the pressure is more evenly distributed on the blank.

[0018] 3. The mold for producing the metal C-shaped sealing ring with cooling function extrude the annular blank in the vertical direction through the extension plates on both sides of the fixed rod, so that the middle part of the annular blank is located in the middle part of the C-shaped plate, which helps to ensure the key dimensions of the C-shaped sealing ring, reduce dimensional deviation, and improve product consistency and interchangeability.

[0019] Fourth, the mold for producing the metal C-shaped sealing ring with cooling function makes the outer surface of the arc plate fit closely with the surface of the annular blank by utilizing the mutual repulsion between the magnetic block and the magnetic strip, thereby avoiding lateral sliding of the annular blank due to excessive mold gap or unstable positioning during processing, thereby reducing problems such as misalignment of the two ends and dimensional deviation.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a mold for producing a metal C-shaped sealing ring with a cooling function, comprising a fixed plate 1, a guide column 2 is fixedly connected to the top of the fixed plate 1, the number of the guide columns 2 is four, and the four guide columns 2 are evenly distributed at the top corners of the fixed plate 1, a top plate 3 is fixedly connected to the top of the guide column 2, and a hydraulic cylinder 4 is fixedly connected to the top of the top plate 3;

[0033] A moving assembly 5, the moving assembly 5 is slidably connected to the guide column 2, and the moving assembly 5 is fixedly connected to the output end of the hydraulic cylinder 4;

[0034] The fixed mold assembly 6 is fixedly installed at the top middle of the fixed plate 1;

[0035] The movable mold assembly 7 is fixedly installed at the top middle of the fixed plate 1, and the movable mold assembly 7 is located inside the fixed mold assembly 6;

[0036] Among them, the movable mold assembly 7 includes a fixing ring 71, which is fixedly installed at the middle of the top of the fixing plate 1. A fixing rod 72 is slidably connected to the outer side of the fixing ring 71. A trapezoidal block 75 is fixedly connected to the end of the fixing rod 72. The fixing rod 72 penetrates the fixing ring 71 and extends to the inside of the fixing ring 71. The hydraulic cylinder 4 drives the square plate 51 to move downward, and the square plate 51 drives the trapezoidal cylinder 55 at the bottom to contact and squeeze the trapezoidal block 75. Under the action of the squeezing force, the trapezoidal block 75 is forced to move the arc-shaped member 76 toward the fixed mold assembly 6 through the fixing rod 72. The arc-shaped member 76 contacts the annular blank and continues to move toward the C-shaped plate 65. Under the mutual squeezing between the C-shaped plate 65 and the arc-shaped member 76, the middle part of the annular blank is squeezed into an inward concave structure. A plurality of arc-shaped members 76 form a ring. At this time, the arc-shaped member applies forces in multiple directions to the inner wall of the annular blank. The radial force, axial force and bending moment are evenly dispersed in all directions, so that the annular blank is evenly stressed and single-point stress concentration is avoided. The trapezoidal block 75 is located inside the fixing ring 71, and the end of the trapezoidal block 75 close to the fixing rod 72 is fixedly connected to a compression spring 73. By setting the compression spring 73 and utilizing the elastic properties of the compression spring 73, the arc-shaped member 76 can automatically adjust the extrusion force on the blank according to the deformation of the metal blank. When the local deformation of the blank is large, the elastic support will correspondingly increase the supporting force on the part, so that the pressure is more evenly distributed on the blank, thereby avoiding defects such as excessive thinning and cracking of the material caused by excessive local pressure, and improving the molding quality and dimensional accuracy of the C-shaped sealing ring. The end of the compression spring 73 away from the trapezoidal block 75 is fixedly connected to the inner wall of the fixing ring 71, and the end of the fixing rod 72 away from the trapezoidal block 75 is fixedly connected to the arc-shaped member 76.

[0037] A cylinder 8 is fixedly connected to the middle of the top of the fixed plate 1 . The cylinder 8 is located at the axis of the fixed ring 71 . A fixed block 9 is fixedly connected to the top of the cylinder 8 . The cylinder 8 and the hydraulic cylinder 4 are located on the same vertical line.

[0038] There are multiple fixing rods 72, and the multiple fixing rods 72 are evenly distributed around the fixing ring 71. The outer side of the fixing rod 72 is fixedly connected with a protrusion 74. There are multiple protrusions 74, and the multiple protrusions 74 are evenly distributed around the fixing rod 72. The fixing rod 72 is fixedly connected with an intermediate plate 78 near the outer side of the arc-shaped member 76. The outer side of the intermediate plate 78 is rotatably connected with an extension plate 79. After the annular blank is placed, the hydraulic cylinder 4 drives the square plate 51 to move downward, and the square plate 51 drives the positioning rod 56 and the trapezoidal cylinder 55 to move. Under the mutual extrusion force between the hypotenuse of the trapezoidal cylinder 55 and the hypotenuse of the trapezoidal block 75, the trapezoidal block 75 drives the fixing rod 72 to move in the direction close to the arc plate 64, so that the extension plate 79 slides inside the through hole 66. At this time, both sides of the fixing rod 72 The extension plate 79 extrude the annular blank in the vertical direction so that the middle part of the annular blank is located in the middle part of the C-shaped plate 65, which helps to ensure the key dimensions of the C-shaped sealing ring, reduce dimensional deviation, and improve the consistency and interchangeability of the product. At the same time, the middle alignment allows the materials on both sides to bend symmetrically around the arc-shaped member 76, avoiding problems such as inconsistent bending angles and different curvature radii due to uneven force on one side, and reducing surface wrinkles, scratches and other defects caused by uneven deformation, thereby obtaining a C-shaped sealing ring with a regular shape and uniformity. There are two extension plates 79, and the two extension plates 79 are symmetrically arranged with the fixing rod 72 as the center. The side of the extension plate 79 away from the fixing rod 72 is fixedly connected with an elastic plate 77, and the end of the elastic plate 77 away from the extension plate 79 is fixedly connected to the middle plate 78.

[0039] The second embodiment is based on the first embodiment. Figure 6 As shown, the arc-shaped member 76 includes a circular tube 761, and the circular tube 761 is fixedly connected to one end of the fixing rod 72 away from the trapezoidal block 75. The outer side of the circular tube 761 is slidably connected to a connecting rod 762, which penetrates the circular tube 761 and extends to the inside of the circular tube 761. One end of the connecting rod 762 is fixedly connected to an arc plate 763. Under the action of the mutual extrusion force between the hypotenuse of the trapezoidal cylinder 55 and the hypotenuse of the trapezoidal block 75, the arc plate 763 moves toward the direction of the annular blank, so that the arc plate 763 contacts the annular blank, and the arc plate 763 is moved toward the direction of the annular blank under the action of the mutual repulsion between the magnetic block 764 and the magnetic strip 765. The outer surface of plate 763 fits tightly with the surface of the annular blank, thereby preventing the annular blank from sliding laterally due to excessive mold gap or unstable positioning during processing, thereby reducing problems such as misalignment and dimensional deviation at both ends. The arc plate 763 is located on the outside of the circular tube 761, and the axis of the circular tube 761 coincides with the axis of the arc plate 763. The end of the connecting rod 762 away from the arc plate 763 is fixedly connected to a magnetic block 764, and the magnetic block 764 is located inside the circular tube 761. The inner wall of the circular tube 761 close to the fixed rod 72 is fixedly connected to a magnetic strip 765, and the magnetic strip 765 and the magnetic block 764 have the same magnetism.

[0040] The third embodiment is based on the first and second embodiments. Figures 7 and 8 As shown, the fixed mold assembly 6 includes a connecting ring 61, which is fixedly installed in the middle of the top of the fixed plate 1, and the connecting ring 61 is sleeved on the outside of the fixed ring 71. The arc-shaped member 76 is located at the interval between the fixed ring 71 and the connecting ring 61. A round rod 62 is fixedly connected to the top of the connecting ring 61. There are multiple round rods 62, and the multiple round rods 62 are evenly distributed around the connecting ring 61. A connecting plate 63 is fixedly connected to the outside of the round rod 62. There are two connecting plates 63. The two connecting plates 63 are symmetrically arranged around the round rod 62. An end of the connecting plate 63 away from the round rod 62 is fixedly connected to an arc plate 64. The outside of the arc plate 64 is fixedly connected to a C-shaped plate 65. There are two arc plates 64. Both ends of the C-shaped plate 65 are fixedly connected to the two arc plates 64. A fixing part 67 is fixedly connected to the top of the plate 1. There are multiple fixing parts 67. The fixing parts 67 and the round rods 62 are alternately arranged. A heat sink 68 is fixedly connected to the outer side of the C-shaped plate 65. Since the sliding friction between the annular blank and the C-shaped plate 65 and the arc plate 763 generates heat, local overheating may cause uneven materials and defects in the concave part. By arranging multiple heat sinks 68 on the outer side of the C-shaped plate 65, a heat dissipation effect is played, which can reduce the softening and oxidation of metal materials caused by local overheating, thereby improving the dimensional accuracy and surface quality of the C-shaped sealing ring. There are multiple heat sinks 68, and the heat sinks 68 are evenly arranged on the heat sink 68. A through hole 66 is opened on the outer side of the arc plate 64, and the extension plate 79 is located inside the through hole 66.

[0041] The fixing member 67 includes a positioning block 671, which is fixedly installed on the top of the fixing plate 1. The positioning block 671 is located between two adjacent arc plates 64. A trapezoidal groove 672 is provided on the top of the positioning block 671. The inner wall of the trapezoidal groove 672 is flush with the edge of the arc plate 64. A contact plate 674 is provided inside the trapezoidal groove 672. The annular blank is placed inside the trapezoidal groove 672 on the positioning block 671 so that the bottom side of the annular blank contacts the top of the contact plate 674. A spring plate 675 is provided to play a buffering role. A sliding rod 673 is fixedly connected to the bottom of the contact plate 674. The sliding rod 673 passes through the positioning block 671, and the end of the sliding rod 673 away from the contact plate 674 is fixedly connected to the spring plate 675.

[0042] For the fourth embodiment, please refer to Figures 9 and 10As shown, the moving assembly 5 includes a square plate 51, which is slidably connected to the guide column 2, and the top of the square plate 51 is fixedly connected to the output end of the hydraulic cylinder 4. A cylinder 52 is arranged inside the square plate 51, and a slide groove 54 is arranged on the outer side of the cylinder 52. The hydraulic cylinder 4 drives the square plate 51 to move downward when it works, and the square plate 51 drives the cylinder 52 to move. The cylinder 52 contacts the arc plate 64, and the cylinder 52 moves inside the square plate 51. At the same time, the fixed block 9 enters the inside of the through groove 57, and extrusion is generated between the fixed block 9 and the slider 59. The return spring 58 is compressed and deformed by force. As the square plate 51 continues to move downward, until the slider 59 stops sliding, the hydraulic cylinder 4 stops working, which plays a role of limiting, thereby avoiding excessive stamping depth. The ring blank is excessively deformed, cracked or the mold is damaged. At the same time, a reasonable downward movement limit can prevent the ring blank from cracking due to excessive extrusion, and at the same time protect the mold from excessive impact, thereby extending the service life of the mold. The cylinder 52 is slidably connected to the square plate 51 through a slide groove 54. An inclined groove 53 is provided at the bottom of the cylinder 52. A positioning rod 56 is fixedly connected to the middle of the bottom of the square plate 51. The cylinder 52 is sleeved on the outside of the positioning rod 56. The bottom of the positioning rod 56 is fixedly connected to a trapezoidal cylinder 55. A through groove 57 is provided on the inner wall of the trapezoidal cylinder 55. A reset spring 58 is fixedly connected to the inner wall of the through groove 57. A slider 59 is slidably connected to the inner wall of the through groove 57. The slider 59 is connected to the trapezoidal cylinder 55 through the reset spring 58.

[0043] When in use, the annular blank is placed inside the trapezoidal groove 672 on the positioning block 671, so that the bottom side of the annular blank contacts the top of the contact plate 674, and the outer surface of the annular blank contacts the surface of the arc plate 64. The hydraulic cylinder 4 drives the square plate 51 to move downward, and the square plate 51 drives the cylinder 52 to move. The cylinder 52 contacts the arc plate 64 and moves inside the square plate 51. At the same time, the fixed block 9 enters the inside of the through groove 57, and extrusion is generated between the fixed block 9 and the slider 59. The return spring 58 is compressed and deformed by force. As the square plate 51 continues to move, the cylinder 52 moves inside the square plate 51. Continuing downward, extrusion occurs between the trapezoidal cylinder 55 and the trapezoidal block 75, and the trapezoidal block 75 drives the fixed rod 72 to move toward the direction close to the arc plate 64, so that the extension plate 79 slides inside the through hole 66. At this time, the extension plates 79 on both sides of the fixed rod 72 extrude the annular blank in the vertical direction, so that the middle part of the annular blank is located in the middle part of the C-shaped plate 65, and then the arc plate 763 contacts the annular blank and continues to move toward the C-shaped plate 65, squeezing a part of the annular blank into a concave structure until the slider 59 stops sliding and the hydraulic cylinder 4 stops working.
