[0029] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0030] It should be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the singular forms "a," "an," and "the" may also be intended to include the plural forms. The terms "comprise," "include," and "have" are inclusive and, therefore, specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0031] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "outer," "inner," "side," "end," "lower," "edge," "inside," "outer," "front," "back," "top," "bottom," etc. Such spatially relative terms are intended to encompass different orientations of the mechanism during use or operation in addition to the orientation depicted in the figures.

[0032] according to Figures 1 to 6 , describing an embodiment of the present utility model.

[0033] According to an embodiment of the present utility model, on the one hand, a stamping die is disclosed, including an upper die base 1, a pressure plate 2, a lower die base 3 and a positioning assembly 4, wherein the pressure plate 2 and the upper die base 1 are slidably connected, the pressure plate 2 has a first molding surface 21, the lower die base 3 has a second molding surface 31, the lower die base 3 can be molded with the upper die base 1 to press the first molding surface 21 and the second molding surface 31, the positioning assembly 4 includes a first positioning portion 41 and a second positioning portion 42, the first positioning portion 41 is arranged on the pressure plate 2, and the second positioning portion 42 is arranged on the lower die base 3, one of the first positioning portion 41 and the second positioning portion 42 is provided with a conical groove 4121, and the other is provided with a conical column 4221, and the conical column 4221 can be fitted in the conical groove 4121.

[0034] The stamping die of the present application is provided with a positioning component 4, and the first positioning part 41 in the positioning component 4 is set on the pressure plate 2, and the second positioning part 42 is set on the lower die base 3, and one of the first positioning part 41 and the second positioning part 42 is provided with a conical groove 4121, and the other is provided with a conical column 4221. During the process of closing the upper die base 1 and the lower die base 3, the conical column 4221 gradually engages in the conical groove 4121 to achieve fine-tuning of the position of the pressure plate 2, ensuring that the first molding surface 21 of the pressure plate 2 and the second molding surface 31 of the lower die base 3 are in line with each other, thereby improving the stamping forming accuracy of the parts and ensuring the production yield of the parts. In addition, the structure of the conical column 4221 engaging with the conical groove 4121 can also offset part of the lateral load on the pressure plate 2 during the stamping process, thereby reducing the situation where the pressure plate 2 is squeezed and damaged, and ensuring the service life of the pressure plate 2.

[0035] It is understandable that some large outer covering parts have large undulations, and correspondingly, the first mold surface 21 of the pressing plate 2 will also have corresponding undulations. When the pressing plate 2 is subjected to pressure during stamping, the undulations of the first mold surface 21 thereon will squeeze the pressing plate 2 laterally, causing the pressing plate 2 to be deformed laterally and outwardly under force. The pressure on the pressing plate 2 will also apply force to the conical column 4221 and the conical groove 4121. The force on the conical column 4221 and the conical groove 4121 will provide a reverse force to the pressing plate 2. The reverse force can offset at least part of the lateral force on the pressing plate 2, thereby reducing the lateral deformation of the pressing plate 2 and ensuring the service life of the pressing plate 2.

[0036] The lower die base 3 is fixedly arranged, and the upper die base 1 is generally connected to a power device and can be driven by the power device to enable the upper die base 1 and the lower die base 3 to be closed or separated and demolded.

[0037] The pressing plate 2 is arranged in the mold cavity of the upper mold base 1, and the gap between the pressing plate 2 and the inner wall of the mold cavity of the upper mold base 1 is matched to facilitate the movement of the pressing plate 2 in the mold cavity when the upper mold base 1 and the lower mold base 3 are closed, so that the first mold surface 21 and the second mold surface 31 can be pressed more accurately.

[0038] Specifically, the blank holder 2 is slidably connected to the cavity of the upper die holder 1 via a guide plate (not shown). Since the assembly of the blank holder 2 and the upper die holder 1 belongs to the prior art, it will not be described in detail here.

[0039] In this embodiment, the tapered groove 4121 is provided in the first positioning portion 41, and the tapered column 4221 is provided in the second positioning portion 42. Of course, in other embodiments, the tapered groove 4121 can also be provided in the second positioning portion 42, and the tapered column 4221 can be provided in the first positioning portion 41, and the present invention is not limited to this embodiment.

[0040] In some embodiments, the positioning assembly 4 further includes a gasket 43 , which is connected between the second positioning portion 42 and the lower mold base 3 , and is used to adjust the height of the second positioning portion 42 .

[0041] There may be thickness differences in the stamping of different parts, or errors during production may cause the docking of the first positioning part 41 and the second positioning part 42 to affect the clamping of the upper mold base 1 and the lower mold base 3. Therefore, in the early debugging stage, the height of the second positioning part 42 can be adjusted by the gasket 43, so that the positioning component 4 as a whole can adapt to the use of the stamping mold to ensure the normal progress of the stamping process.

[0042] For example, the height of the second positioning portion 42 can be reduced by grinding the pad 43 to make it thinner, but the present invention is not limited thereto. In other embodiments, the height of the second positioning portion 42 can be adjusted by adjusting the number of the pads 43 .

[0043] Specifically, the gasket 43 can be made of a grindable material. When the height of the second positioning portion 42 needs to be adjusted, the gasket 43 is removed from the lower die base 3 and ground, and then the ground gasket 43 is installed on the lower die base 3 .

[0044] In some embodiments, the second positioning portion 42 and the gasket 43 are provided with corresponding connecting holes 431 , and the positioning assembly 4 further includes a connecting member installed in the connecting hole 431 to connect the second positioning portion 42 and the gasket 43 .

[0045] By setting a connecting hole 431 on the second positioning part 42 and the gasket 43 and using a connecting piece to be installed in the connecting hole 431, the second positioning part 42 and the gasket 43 are connected, which facilitates the storage of the gasket 43 and the second positioning part 42 together and avoids the loss of the gasket 43.

[0046] For example, the connection hole 431 may be a bolt hole, and the connection member may be a bolt. The bolt is inserted into the bolt hole of the gasket 43 and the second positioning portion 42 to achieve bolt fixation of the gasket 43 and the second positioning portion 42, but the present invention is not limited thereto. In other embodiments, the connection hole 431 may also be a rivet hole, and the connection member may be a rivet. The rivet is driven into the rivet hole to achieve riveted fixation of the gasket 43 and the second positioning portion 42.

[0047] To improve connection reliability, multiple connection holes 431 and multiple connectors can be provided, and multiple connectors can be connected to the connection holes 431 in a one-to-one correspondence, thereby achieving multiple connectors to connect and fix the gasket 43 and the second positioning portion 42. For ease of description, this embodiment is described as having two connection holes 431 and two connectors.

[0048] In some embodiments, the positioning assembly 4 further includes a first positioning pin, and the first positioning portion 41 is provided with a first positioning hole 4122 . The first positioning pin positions the first positioning portion 41 on the pressing plate 2 through the first positioning hole 4122 .

[0049] A first positioning hole 4122 is provided in the first positioning portion 41 , and a first positioning pin positions the first positioning portion 41 on the pressing plate 2 through the first positioning hole 4122 , thereby ensuring the position accuracy of the first positioning portion 41 on the pressing plate 2 .

[0050] Specifically, the position of the first positioning portion 41 on the pressing plate 2 is determined through calculation / design, and then the first positioning pin is driven into the first positioning hole 4122 on the first positioning portion 41 and fixed to the pressing plate 2, thereby positioning the first positioning portion 41 on the pressing plate 2, ensuring the installation accuracy of the first positioning portion 41.

[0051] For example, the first positioning hole 4122 is opened at the center of the first positioning portion 41 to position the center of the first positioning portion 41 on the pressing plate 2 .

[0052] In some embodiments, the first positioning portion 41 includes a first positioning seat 411 and a first docking portion 412 , wherein the first positioning seat 411 is fixed to the pressing plate 2 , the first docking portion 412 is fixed to the first positioning portion 41 , and a conical groove 4121 is provided on the first docking portion 412 .

[0053] The first positioning seat 411 supports and fixes the first docking portion 412 . The first docking portion 412 is provided with a tapered groove 4121 for easy cooperation with the second positioning portion 42 .

[0054] Specifically speaking of installation, in some embodiments, the first positioning seat 411 is provided with a first mounting hole 4111 , and the first positioning portion 41 further includes a first mounting member, which is fixedly connected to the pressing plate 2 via the first mounting hole 4111 .

[0055] A first mounting hole 4111 is provided in the first positioning seat 411 , and the first mounting member is passed through the first mounting hole 4111 and fixedly connected to the pressing plate 2 , thereby achieving fixed connection between the first positioning seat 411 and the pressing plate 2 .

[0056] For example, the first mounting hole 4111 is a light hole, and the blank holder 2 is provided with a threaded hole corresponding to the light hole. The first mounting member is a threaded member, which passes through the light hole and is threadedly fixed in the threaded hole of the blank holder 2, but the present invention is not limited thereto. In other embodiments, the first mounting hole 4111 can be a pin hole, and the corresponding first mounting member is provided as a pin, which is assembled in the pin hole and fixed to the blank holder 2.

[0057] In this embodiment, the first positioning seat 411 and the first docking portion 412 are arranged concentrically, the conical groove 4121 is arranged at the center position of the first docking portion 412, the first positioning hole 4122 is arranged at the center position of the first positioning seat 411 and the first docking portion 412, and one end of the first positioning hole 4122 passes through the first positioning seat 411, and the other end of the first positioning hole 4122 is connected to the conical groove 4121.

[0058] The first mounting holes 4111 are arranged along the outer periphery of the first positioning hole 4122. To improve the connection reliability between the first positioning portion 41 and the blank holder 2, multiple first mounting holes 4111 and multiple first mounting members can be provided. By providing multiple first mounting members in a one-to-one correspondence with the first mounting holes 4111, the first positioning seat 411 is firmly connected to the blank holder 2. In this embodiment, two first mounting holes 4111 and two first mounting members are provided as an example for illustrative description.

[0059] In some embodiments, the positioning assembly 4 further includes a second positioning pin, and the second positioning portion 42 is provided with a second positioning hole 4222 . The second positioning pin positions the second positioning portion 42 on the lower mold base 3 through the second positioning hole 4222 .

[0060] A second positioning hole 4222 is provided in the second positioning portion 42 , and a second positioning pin positions the second positioning portion 42 on the lower die base 3 through the second positioning hole 4222 , thereby ensuring the position accuracy of the second positioning portion 42 on the lower die base 3 .

[0061] Specifically, the position of the second positioning portion 42 on the lower die base 3 is determined through calculation / design, and then the second positioning pin is driven into the second positioning hole 4222 on the second positioning portion 42 and fixed to the lower die base 3, thereby achieving the positioning of the second positioning portion 42 on the lower die base 3, ensuring the installation accuracy of the second positioning portion 42.

[0062] For example, the second positioning hole 4222 is opened at the center of the second positioning portion 42 to position the center of the second positioning portion 42 on the lower mold base 3 .

[0063] In some embodiments, the second positioning portion 42 includes a second positioning seat 421 and a second docking portion 422 , wherein the second positioning seat 421 is fixed to the lower mold base 3 , the second docking portion 422 is fixed to the second positioning portion 42 , and a conical column 4221 is provided on the second docking portion 422 .

[0064] The second positioning seat 421 supports and fixes the second docking portion 422 . The second docking portion 422 is provided with a tapered column 4221 for easy cooperation with the first positioning portion 41 .

[0065] Specifically speaking of installation, in some embodiments, the second positioning seat 421 is provided with a second mounting hole 4211 , and the positioning assembly 4 further includes a second mounting member, which is fixedly connected to the lower mold base 3 via the second mounting hole 4211 .

[0066] A second mounting hole 4211 is provided in the second positioning seat 421 , and the second mounting member is passed through the second mounting hole 4211 and fixedly connected to the lower mold base 3 , thereby achieving fixed connection between the second positioning seat 421 and the lower mold base 3 .

[0067] For example, second mounting hole 4211 is a light hole, and lower mold base 3 is provided with a threaded hole corresponding to the light hole. The second mounting member is a threaded member that passes through the light hole and is threadedly fixed in the threaded hole of lower mold base 3, but the present invention is not limited to this. In other embodiments, second mounting hole 4211 can be a pin hole, and the corresponding second mounting member is configured as a pin, which is assembled into the pin hole and fixed to lower mold base 3.

[0068] In this embodiment, the second positioning seat 421 and the second docking portion 422 are arranged concentrically, the conical column 4221 is arranged at the center position of the second docking portion 422, the second positioning hole 4222 is arranged at the center position of the second positioning seat 421 and the second docking portion 422, and one end of the second positioning hole 4222 passes through the second positioning seat 421, and the other end of the second positioning hole 4222 passes through the center of the conical column 4221.

[0069] Correspondingly, the connecting hole 431 is provided along the outer periphery of the second positioning hole 4222 , and the second mounting hole 4211 is provided along the outer periphery of the connecting hole 431 .

[0070] To improve the connection reliability between the second positioning portion 42 and the lower mold base 3, multiple second mounting holes 4211 and multiple second mounting members can be provided. By providing multiple second mounting members in a one-to-one correspondence with the second mounting holes 4211, the second positioning base 421 is firmly connected to the lower mold base 3. In this embodiment, two second mounting holes 4211 and two second mounting members are provided as an example for illustrative description.

[0071] Furthermore, when the positioning assembly 4 includes a gasket 43, the gasket 43 and the second positioning seat 421 are arranged concentrically, and through holes are provided on the gasket 43 at positions corresponding to the second positioning hole 4222 and the second mounting hole 4211 to facilitate the assembly of the second positioning pin and the second mounting member.

[0072] In some embodiments, the taper of the tapered groove 4121 is 90 degrees, and the taper of the corresponding tapered column 4221 is also set to 90 degrees. In other embodiments, the taper of the tapered groove 4121 and the tapered column 4221 can also be set to 120 degrees or other values, which is not limited to this embodiment.

[0073] For example, the tapered groove 4121 may be a conical groove 4121 , and the tapered column 4221 may specifically be a conical column 4221 , and the conical column 4221 matches and engages with the tapered groove 4121 .

[0074] Specifically, the shapes of the gasket 43 and the second positioning seat 421 are consistent. The first positioning seat 411 and the second positioning seat 421 can be configured in any shape to accommodate different installation spaces, such as a circle, rectangle, or ellipse. The first docking portion 412 and the second docking portion 422 can be configured in a cylindrical shape or a geometric cube shape. For ease of description, this embodiment assumes that the first positioning seat 411 and the second positioning seat 421 are configured in a rectangular shape with one of the two opposing edges configured in an arc shape, and the first docking portion 412 and the second docking portion 422 are configured in a cylindrical shape.

[0075] In some embodiments, the first molding surface 21 and the second molding surface 31 are provided with corresponding air-avoidance areas, and the positioning assembly 4 is disposed in the air-avoidance areas. If the first molding surface 21 and the second molding surface 31 are provided with corresponding air-avoidance areas, the positioning assembly 4 can be disposed in the air-avoidance areas, eliminating the need for additional corresponding areas for mounting the positioning assembly 4, which facilitates the small-sized configuration of the stamping die.

[0076] It should be noted that since large outer covers often have holes to facilitate the installation of other components (such as lights or door handles), corresponding air-avoidance areas need to be provided on the first and second profiles 21, 31 to avoid these holes when stamping the large outer cover. Therefore, the holes corresponding to the air-avoidance areas do not participate in the stamping of the product, so that the product still retains the hole structure after stamping. Therefore, the air-avoidance areas are actually grooves provided on the first and second profiles 21, 31, and the size of the grooves matches the holes in the large outer cover.

[0077] In other embodiments, at least two positioning assemblies 4 are provided, and the at least two positioning assemblies 4 are provided along opposite sides or around the blank pressing plate 2. The at least two positioning assemblies 4 are dispersed along opposite sides or around the blank pressing plate 2 to ensure the stability of the center of the blank pressing plate 2 by the at least two positioning assemblies 4, thereby ensuring the stability of the blank pressing plate 2 during the stamping process.

[0078] It should be noted that, in order to ensure good cooperation between the tapered column 4221 and the tapered groove 4121, a pressure source is usually arranged just above the pressing plate 2, such as Figure 1 As shown, the upper hitting rod 100 is spaced apart and arranged just above the pressing plate 2 .

[0079] To facilitate understanding of the stamping die of this embodiment, the following is an introduction to its installation and use process:

[0080] Installation process: determine the installation point position of the first positioning portion 41 on the blank pressing plate 2 and the installation point position of the second positioning portion 42 on the lower die base 3, place the first positioning portion 41 and the second positioning portion 42 at the corresponding installation points respectively, use the first positioning member to punch the first positioning hole 4122 and the blank pressing plate 2 to position the first positioning portion 41 on the blank pressing plate 2, use the second positioning member to punch the second positioning hole 4222 and the lower die base 3, position the second positioning portion 42 on the lower die base 3, then the first mounting member passes through the first mounting hole 4111 and is connected and fixed to the blank pressing plate 2, and the second mounting member passes through the second mounting hole 4211 and the through hole on the gasket 43 and is connected and fixed to the lower die base 3;

[0081] Usage process: the upper die base 1 gradually moves downward and closes the mold with the lower die base 3, and the first positioning part 41 and the second positioning part 42 on the pressing plate 2 are docked and matched, and the conical column 4221 therein gradually engages in the conical groove 4121 to drive the pressing plate 2 to fine-tune its position, ensuring that the first molding surface 21 of the pressing plate 2 and the second molding surface 31 of the lower die base 3 are in line with each other, and in the process of the pressing plate 2 being pressed together, when the pressing plate 2 is subjected to lateral extrusion force / thrust / load, the matching structure of the conical column 4221 and the conical groove 4121 can provide a reaction force to the pressing plate 2, thereby at least offsetting part of the lateral extrusion force / thrust / load exerted on the pressing plate 2.

[0082] According to an embodiment of the present invention, on the other hand, a vehicle parts production device is disclosed, including the stamping die of this embodiment.

[0083] Since the vehicle parts production equipment of the present application includes the stamping die of the present application, it has the same technical effect as the stamping die (see above for details), and this embodiment will not be repeated here.

[0084] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in this application should be included in the scope of protection defined in this application.
