Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a stamping mold. Background Art

[0002] Among stamped products, terminals with squared edges are typically closed squares. Due to their unique structure, the bending punch cannot fit within the square slot, so conventional forming methods are not usually feasible. The general forming steps are: two-step pre-forming, followed by a clamping method to create the approximate shape, and finally, a forming punch is used to achieve square shaping. The forming punch head needs to be formed into a deep "U" groove that mimics the opening of the square frame. Since there is no material removal process, the forming punch will pull the terminal upward when it is disengaged after forming. In severe cases, the terminal will deform and cause production anomalies. This factor also affects the terminal production speed and efficiency. Utility Model Content

[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0043] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] In the description of this utility model, "a number" refers to one or more, and "a plurality" refers to two or more. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0045] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0046] The square terminal includes an enclosed square cavity. Before forming, the square terminal is a whole piece of sheet material. The sheet material can be divided into a bottom plate, a first side plate and a second side plate connected to the opposite side of the bottom plate, a first top plate connected to the side of the first side plate away from the second side plate, and a second top plate connected to the side of the second side plate away from the first side plate according to the shape after forming. The forming steps of forming the sheet material into the square terminal include:

[0047] In the first step, the first side panel together with the first top panel, and the second side panel together with the second top panel are bent relative to the bottom panel, and the bending angle can be adjusted according to actual needs;

[0048] In the second step, the forming punch empties the bent square terminal, that is, the forming punch forms a forming cavity with a rectangular cavity, and forms the square terminal within the forming cavity. The various plates of the square terminal correspond to the peripheral walls of the rectangular cavity. Specifically, the first top plate and the second top plate together form the top plate, which can be relative and spaced, or partially overlapped, and the bottom plate, the first side plate, the second side plate and the top plate respectively correspond to the peripheral walls of the rectangular cavity.

[0049] Among them, the head of the forming punch needs to be made into a deep "U" groove imitating the square frame mouth. Since there is no material removal process, the forming punch will pull the terminal upward when it is disengaged after forming is completed. In severe cases, the terminal will be deformed, causing production abnormalities.

[0050] Reference Figures 1 to 7 As shown, an embodiment of the present utility model proposes a stamping die including: a first die assembly 100 and a second die assembly 200. The first die assembly 100 and the second die assembly 200 are molded together along a stamping direction to form square-shaped terminals. When the first die assembly 100 and the second die assembly 200 are parted along a parting direction opposite to the stamping direction, the square-shaped terminals can automatically escape from the forming punch to reduce the probability of production abnormalities and improve production efficiency.

[0051] The first mold assembly 100 includes a stamping seat 110, a stopper portion 122 and a forming portion 132 provided on the same end of the stamping seat 110. The stamping seat 110 includes a plurality of templates stacked along the stamping direction. The various components located within the first mold assembly 100 are mounted through the templates. Specifically, two adjacent templates can be clamped and fixed, or fixed to the templates by bolts. The side of the stamping seat 110 opposite to the second mold assembly 200 along the stamping direction is the first stamping surface. The first mold assembly 100 also includes The stopper 120 and the forming part 130 are provided in the stamping seat 110 along the stamping direction. The stopper 120 includes a first main body 121 and a stopper 122 connected to the first main body 121. The stopper 122 is located at one end of the first main body 121 facing the first stamping surface. The stopper 122 has a stopper surface for stopping. The stopper surface can be the end face of the first main body 121, or it can be a plane away from the first main body 121 in the protruding part of the end face of the first main body 121. The forming member 130 is arranged along the stamping direction and connected to the stamping seat 110. The forming member 130 includes a second main body 131 and a forming portion 132 connected to the second main body 131. The forming portion 132 is located at the end of the first main body 121 facing the first stamping surface. The forming portion 132 is a rectangular protrusion protruding from the end surface of the first main body 121. The side of the forming portion 132 away from the first main body 121 forms a first forming surface. When forming a square-shaped terminal, the bottom plate of the sheet material is located on the first forming surface. During forming, the first forming surface is used to form the bottom plate of the square-shaped terminal. The connection between the outer peripheral surface of the forming portion 132 and the end surface can be rounded to smooth the transition and increase structural strength.

[0052] The second mold assembly 200 is clamped to the first mold assembly 100 along the stamping direction. When clamped, the first mold assembly 100 and the second mold assembly 200 form a molding cavity 300 and the square terminal is molded in the molding cavity 300.

[0053] The second mold assembly 200 includes a main mold body 210, a first stamping part 220, a second stamping part 230, a demolding part 240, and an elastic component 260. The main mold body 210 also includes a plurality of templates stacked along the stamping direction. The various components located within the second mold assembly 200 are mounted through the templates. Specifically, two adjacent templates can be clamped and fixed, or they can be fastened to the templates by bolts. Among them, the surface of the main mold body 210 opposite to the stamping seat 110 along the stamping direction is the second stamping surface. When the mold is closed, the first stamping surface and the second stamping surface are in contact.

[0054] The first stamping part 220 is connected to the main mold body 210. The first stamping part 220 is opposite to the forming part 132 along the stamping direction and the relative end face is defined by a forming groove 221. The forming part 132 is located within the forming groove 221. The groove opening of the forming groove 221 is blocked by the forming part 132 to form a rectangular cavity-shaped forming cavity 300. The two opposite groove walls of the forming groove 221 respectively form a second forming surface and a third forming surface. The second forming surface is used to form the first side plate of the square terminal, and the second forming surface is used to form the second side plate of the square terminal.

[0055] The second stamping member 230 is inserted through the main mold body 210 along the stamping direction. Insertion means that one end of the second stamping member 230 is inserted into or extends out of the main mold body 210 along the stamping direction and is movable relative to the main mold body 210 along the stamping direction. The demolding member 240 is integrally connected to the second stamping member 230 or detachably connected. The integral connection method includes integral molding or welding. The detachable connection method includes detachable connection via bolts, pins, and other connecting members.

[0056] The second stamping part 230 abuts against the stop portion 122 along the stamping direction, and the demolding part 240 is located in the forming groove 221 and is opposite to and spaced from the forming portion 132 along the stamping direction. The side of the demolding part 240 facing the forming portion 132 replaces the bottom wall of the forming groove 221 to form a fourth molding surface, and the fourth molding surface is used to form the top plate of the square terminal.

[0057] The two opposite surfaces of the molding portion 132 and the demolding member 240 and the two opposite side walls of the molding groove 221 together form a molding cavity 300 for molding products. Specifically, the first molding surface, the second molding surface, the third molding surface and the fourth molding surface form a rectangular cavity-shaped molding cavity 300 within the molding groove 221 to form square-shaped terminals.

[0058] The first template 250 and the elastic component 260 are both connected to the main mold body 210. The first template 250 is separated from the end of the second stamping part 230 away from the stop portion 122. The elastic component 260 is arranged between the first template 250 and the second stamping part 230 and has elastic potential energy, so that the second stamping part 230 has a tendency to move along the stamping direction; in other words, during the process of closing the first mold assembly 100 and the second mold assembly 200, the elastic component 260 will be compressed or stretched due to the displacement during the closing of the mold, resulting in the elastic component 260 having elastic potential energy after closing the mold, so that the elastic force of the elastic component 260 will drive the second stamping part 230 to move along the stamping direction, but the second stamping part 230 is in contact with the abutment portion, resulting in the second stamping part 230 being unable to move and having a tendency to move along the stamping direction, wherein the second stamping part 230 has a tendency to move along the stamping direction relative to the main mold body 210.

[0059] The second mold assembly 200 is configured as follows: the second mold assembly 200 is separated from the first mold assembly 100 along the mold separation direction opposite to the stamping direction, and the elastic component 260 releases elastic potential energy and drives the demolding member 240 to separate the molding groove 221 and the product in the molding groove 221. Specifically, during mold separation, the first mold assembly 100 and the second mold assembly 200 are separated along the mold separation direction, resulting in the second stamping member 230 having space to move along the stamping direction. The elastic component 260 releases elastic potential energy, so that the second stamping member 230 is driven by the elastic component 260 to continuously abut against the stopper 122, the demolding member 240 remains stationary relative to the packaged terminal in the molding cavity 300, and the demolding member 240 limits the movement of the molded packaged terminal along the mold separation direction. It can also be understood that the demolding member 240 moves relative to the main mold body 210 along the stamping direction and continuously abuts against the stopper 122. The main mold body 210 and the first stamping part 220 move along the parting direction, so that the forming groove 221 moves along the parting direction. The forming groove 221 moves along the parting direction relative to the square-shaped terminal in the molding cavity 300, causing the forming groove 221 to separate from the square-shaped terminal stopped by the demolding part 240, thereby realizing the ejection of the square-shaped terminal in the forming groove 221.

[0060] It is worth understanding that after the first mold assembly 100 and the second mold assembly 200 are closed, the product is molded in the molding cavity 300. When the mold is separated, the first stamping part 220 moves along the demolding direction, and the second stamping part 230 is supported by the elastic component 260 and still abuts against the stop part 122, so that the demolding part 240 remains stationary and fixes the product along the demolding direction. The molding groove 221 detaches from the product along the demolding direction, realizing automatic separation of the product and the molding groove 221, effectively reducing the probability of production abnormalities of the product and improving the production efficiency of the product.

[0061] Reference Figure 3 and Figure 4 As shown, in other embodiments of the present invention, the second stamping part 230 can be limited to the main mold body 210 along the parting direction; wherein, the second stamping part 230 is configured as follows: when the forming groove 221 is separated from the product, the second stamping part 230 is limited to the main mold body 210 along the parting direction so as to move along the parting direction.

[0062] It is worth noting that by limiting the second stamping part 230 along the parting direction, the second stamping part 230 will not be constantly in contact with the stop portion 122 under the drive of the elastic component 260, but will move along the parting direction with the main mold body 210, so that the second stamping part 230 is separated from the stop portion 122, and the first mold assembly 100 and the second mold assembly 200 are completely separated, which facilitates the removal of the product and the next processing, thereby improving processing efficiency. In addition, the second stamping part 230 is limited to the main mold body 210 along the parting direction, and the second stamping part 230 will not be driven by the elastic component 260 to move along the stamping direction, so that the elastic component 260 has a preset potential energy. The elastic potential energy of the elastic component 260 during mold closing is the sum of the preset potential energy and the deformation potential energy of the elastic component 260 during mold closing. The preset potential energy facilitates the control of the elastic force applied by the elastic component 260 to the square terminal.

[0063] Reference Figure 4 and Figure 6 As shown, in some specific embodiments of the present invention, the second mold assembly 200 also includes a second limiting portion 212 connected to the main mold body 210 and a fourth limiting portion 231 connected to the second stamping part 230. The second limiting portion 212 and the fourth limiting portion 231 can be limited and matched along the mold splitting direction.

[0064] In this embodiment, the outer peripheral surface of the second stamping part 230 is defined with a first limiting groove along the stamping direction, and the template of the main mold body 210 is connected to a first limiting plate by bolts. Part of the first limiting plate is located in the first limiting groove and can abut against both ends of the first limiting groove along the stamping direction, wherein the length of the first limiting groove along the stamping direction is greater than or equal to the sum of the length of the first limiting plate along the stamping direction and the deformation length of the elastic component 260 along the stamping direction during the mold closing process. The sum of the deformation lengths of the elastic component 260 along the stamping direction during the mold closing process is equivalent to the movement distance of the demolding member 240 relative to the forming through-slot 221 along the stamping direction. As another embodiment, the outer peripheral surface of the second stamping part 230 can also be connected to the protruding first limiting plate, and the main mold body 210 can be defined with a first limiting groove along the stamping direction.

[0065] Reference Figure 4 and Figure 6 As shown, in some specific embodiments of the present invention, the second mold assembly 200 also includes a first limiting portion 211 connected to the main mold body 210 and a third limiting portion 222 connected to the first stamping part 220. The first stamping part 220 is passed through the main mold body 210, and the first limiting portion 211 and the third limiting portion 222 are connected in a limiting manner along the mold splitting direction.

[0066] It is worth understanding that the first stamping part 220 is limitedly connected to the main mold body 210 , and the assembly of the first stamping part 220 and the main mold body 210 is more convenient.

[0067] In this embodiment, the outer circumferential surface of the first stamping part 220 defines a second limiting groove along the stamping direction, and the template of the main mold body 210 is connected to a second limiting plate via bolts. The second limiting plate is partially located within the second limiting groove and is capable of abutting against both ends of the second limiting groove along the stamping direction. As another embodiment, the outer circumferential surface of the first stamping part 220 may be connected to a protruding second limiting plate, and the main mold body 210 may define a second limiting groove along the stamping direction.

[0068] Reference Figure 1 As shown, in some specific embodiments of the present invention, the first stamping part 220 and the second stamping part 230 are arranged side by side along the stamping direction.

[0069] In this embodiment, the main mold body 210 defines a main mounting hole, which includes a first mounting hole and a second mounting hole that are connected. The first stamping part 220 is mounted in the first mounting hole, and the second stamping part 230 is mounted in the second mounting hole. One side of the first stamping part 220 is opposite and abuts against one side of the second stamping part 230. The processing of the separate main mounting holes is more convenient and also facilitates the positioning of the first stamping part 220 and the second stamping part 230. Among them, the first stamping part 220 is rectangular, and the second stamping part 230 is also rectangular.

[0070] As another embodiment, a mounting groove may be provided in the first stamping part 220 , the groove direction of the mounting groove is consistent with the groove direction of the forming groove 221 , the mounting groove and the forming groove 221 are arranged side by side, and the second stamping part 230 is arranged in the mounting groove.

[0071] Reference Figure 1 As shown, in some specific embodiments of the present invention, the first mold assembly 100 also includes a stop member 120 and a forming member 130 arranged in parallel along the stamping direction, the stop member 120 includes a first main body portion 121 connected to the stop portion 122, and the forming member 130 includes a second main body portion 131 connected to the forming portion 132.

[0072] It is worth understanding that the stopper 120 and the forming part 130 are independently provided, and the stopper 120 and the forming part 130 can be manufactured separately. Moreover, when manufacturing different products, it is sufficient to replace the forming part 130, which has a wider adaptability range and is more convenient for mold modification. Similarly, when the service life of the stopper 120 and the forming part 130 is inconsistent, if one of them needs to be replaced, only the corresponding part needs to be replaced. The replacement of the stopper 120 and the forming part 130 after reaching the service life is more convenient and the cost of use is lower. As another embodiment, the stamping seat 110 includes a separate seat body, and the stopper 120 and the forming part 130 are connected as a whole, for example, integrally formed or welded together.

[0073] Reference Figure 1 As shown, in some specific embodiments of the present invention, the notch position of the forming through groove 221 is defined with a guide chamfer 2211 .

[0074] It is worth understanding that after the first step of sheet material processing is completed, there are angles between the first side panel and the first top panel, the second side panel and the second top panel and the bottom panel. The first side panel and the first top panel, the second side panel and the second top panel are guided by the guide chamfer 2211 so that they continue to bend between the two until they are 90° or more than 90° to the bottom panel and enter the forming groove 221. Within the forming groove 221, the first side panel and the second side panel maintain a 90° angle with the bottom panel, and the first top panel and the second top panel abut against the demolding member 240 and continue to bend relative to each other until the top panel is formed, thereby forming the square terminal.

[0075] In this embodiment, the guide chamfer 2211 is a chamfered angle, and the inner portion of the forming through slot 221 excluding the guide chamfer 2211 includes two opposite and parallel slot walls to meet the forming requirements of square terminals.

[0076] Reference Figure 1 As shown, in other embodiments of the present invention, the second stamping part 230 includes a first stamping part and a second stamping part arranged in parallel along the stamping direction, the demolding part 240 includes a first demolding part connected to the first stamping part and a second demolding part connected to the second stamping part, and the elastic component 260 includes a first elastic part 261 arranged between the first stamping part and the first template 250 and a second elastic part 263 arranged between the second stamping part and the first template 250.

[0077] It is worth understanding that the first demolding component and the second demolding component respectively form the first top plate and the second top plate, so that the first top plate and the second top plate can be formed separately, which is convenient for controlling the order of their forming, especially when there is partial overlap between the first top plate and the second top plate, the first top plate and the second top plate need to be formed in a certain order.

[0078] In this embodiment, the first elastic member 261 and the second elastic member 263 are offset along the axial direction of the square terminal. This allows the first elastic member 261 to apply a different torque to the first demolding member than the second elastic member 263 to apply a different torque to the second demolding member. This in turn results in different bending speeds for the first and second top plates. In another embodiment, the first elastic member 261 and the second elastic member 263 may have different structures, resulting in different elastic forces.

[0079] Reference Figure 1As shown, in some specific embodiments of the present invention, two ends of the first elastic member 261 respectively abut against the first stamping component and the first template 250 along the stamping direction.

[0080] It is worth noting that the first elastic member 261 directly abuts against the first stamping sub-member and the first template 250, which simplifies the structure, makes installation more convenient, and reduces the cost. In this embodiment, the two ends of the second elastic member 263 abut against the second stamping sub-member and the first template 250 along the stamping direction.

[0081] Reference Figure 1 As shown, in some specific embodiments of the present invention, the elastic component 260 further includes a first guide rod 262 , and the first guide rod 262 is disposed between the first elastic member 261 and the first stamping member.

[0082] It is worth noting that the first elastic member 261 is guided and abutted against the first stamping sub-component by the first guide rod 262. The abutment between the first guide rod 262 and the first stamping sub-component is more stable, thereby improving stability during use and achieving higher stamping precision. In this embodiment, the elastic component 260 also includes a second guide rod 264, which is arranged between the second elastic member 263 and the second stamping sub-component. The first guide rod 262 includes a central rod portion and an abutment ring portion connected to the outer peripheral surface of the central rod portion. One end of the central rod portion is inserted into the first elastic member 261, and the other end abuts against the end face of the first stamping sub-component.
