DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] Please refer to Figures 1-4 In the embodiments of the utility model, a lateral punch die comprises an upper die holder 1 and a lower die holder 2 which are in butt joint cooperation through guide columns, the upper end face of the lower die holder 2 is fixedly connected with two mounting frame seats 3 which are oppositely arranged, a positioning seat 4 for product placement is fixedly connected between the two mounting frame seats 3, a moving seat 5 is slidably embedded in the mounting frame seat 3, the lower end of the moving seat 5 is provided with a sliding block 6, the mounting frame seat 3 is provided with a sliding groove 7 for the sliding block 6 to slide, the sliding direction of the sliding block 6 in the sliding groove 7 is the same as the sliding direction of the moving seat 5 in the mounting frame seat 3, wherein the first elastic element 8 which is in elastic abutting cooperation with the sliding block 6 is mounted in the sliding groove 7, and the moving seat 5 is horizontally connected with a punch 9 towards the positioning seat 4.

[0033] The lower end of the upper die seat 1 is longitudinally connected with a downward pushing block 10, which can be inserted into the mounting frame seat 3 and abut with the moving seat 5 to drive the moving seat 5 to slide along the mounting frame seat 3 and towards the side direction of the positioning seat 4, accompanied by the abutment of the upper die and the lower die.

[0034] The lower end of the upper die seat 1 is longitudinally connected with an elastic pressing assembly 11 corresponding to the positioning seat 4.

[0035] In the technical scheme of the utility model, two opposite mounting frame seats 3 are arranged on the lower die seat 2, and a positioning seat 4 for placing products is fixedly connected between the two mounting frame seats 3, so that the products are preliminarily positioned. The punch 9 connected to the moving seat 5 performs a punching action in the stamping process. The sliding block 6 at the lower end of the moving seat 5 cooperates with the sliding groove 7 in the mounting frame seat 3. The sliding block 6 is elastically abutted by the first elastic element 8 (which can be a spring, a nitrogen spring, etc.) in the sliding groove 7. When the moving seat 5 is subjected to the thrust of the downward pushing block 10 of the upper die seat 1, the moving seat 5 can stably slide towards the positioning seat 4 along the direction of the sliding groove 7, so that the punch 9 can accurately punch the side surface of the product located on the positioning seat 4. The buffering and resetting action of the first elastic element 8 ensures the movement accuracy and stability of the moving seat 5 and the punch 9, effectively solving the problem of low lateral positioning accuracy of the traditional die.

[0036] The upper die seat 1 and the lower die seat 2 are in abutment cooperation through guide columns, ensuring the accuracy and stability of the upper and lower die seats 2 during the die closing process. The downward pushing block 10 at the lower end of the upper die seat 1 is inserted into the mounting frame seat 3 and abuts with the moving seat 5 when the upper and lower dies are abutted, directly and stably transmitting the downward power of the upper die seat 1 to the moving seat 5, so that the moving seat 5 obtains sufficient and stable power to push the punch 9 to perform punching operation. Compared with the unstable power transmission mode of the traditional die, this direct abutment transmission design reduces the energy loss and uneven distribution problem in the power transmission process, ensuring that the punch can obtain stable and efficient punching force.

[0037] The elastic pressing assembly 11 at the lower end of the upper die holder 1 corresponds to the positioning seat 4, and during the stamping process, when the upper and lower dies are closed, the elastic pressing assembly 11 first exerts a certain pressure on the product on the positioning seat 4, further presses and fixes the product on the positioning seat 4, prevents the product from being displaced due to lateral force during the punching process, and at the same time, after the punching is completed, the elastic pressing assembly 11 can also assist the product to be smoothly demolded, ensuring the stability of the product and the continuity of the processing during the entire punching process.

[0038] In summary, through the accurate positioning principle design, the problem of large punching position error can be effectively avoided, the punching precision of the product is greatly improved, the defective rate is reduced, the overall quality and performance reliability of the product are improved, and the produced parts can better meet the high-precision assembly and use requirements; the stable and efficient stamping power transmission principle ensures that the punch 9 can obtain stable and sufficient punching force during punching, thereby effectively solving the quality problems of irregular punching edge, burr and incomplete punching, reducing the subsequent secondary processing procedures, saving the production cost, improving the production efficiency, and ensuring that the punching quality of the product meets the high-standard production demand.

[0039] In the embodiment of the utility model, the lower pressing block 10 is provided with a first inclined surface 12, and the moving seat 5 is provided with a second inclined surface 13 which is in abutment with the first inclined surface 12.

[0040] The inclination angle of the first inclined surface 12 is the same as the inclination angle of the second inclined surface 13.

[0041] When the lower pressing block 10 goes down with the upper die seat 1, the first inclined surface 12 arranged on the lower pressing block 10 gradually contacts and interacts with the second inclined surface 13 on the moving seat 5. Since the inclined angles of the first inclined surface 12 and the second inclined surface 13 are the same, according to the mechanical principle of the inclined surface, when the lower pressing block 10 moves vertically downward, a horizontal component force is generated on the moving seat 5, which can effectively convert the vertical pressure into the power for driving the moving seat 5 to slide along the mounting frame seat 3 to the side of the positioning seat 4, thereby driving the punch 9 to perform the lateral punching operation on the product. Through the ingenious design of the inclined surface, the direction conversion and efficient transmission of the force are realized, so that the punching operation of the die is more smooth and accurate.

[0042] In the embodiment of the utility model, the step part 14 is arranged in the chute 7 and is opposite to the sliding block 6, a first slot 15 is arranged on one side of the step part 14 opposite to the sliding block 6, a second slot 16 is arranged on one side of the sliding block 6 opposite to the step part 14, and the left and right ends of the first elastic element 8 are respectively installed in the first slot 15 and the second slot 16.

[0043] The first slot 15 and the second slot 16 are arranged on the step part 14 and the sliding block 6 respectively to provide a stable mounting position for fixing the first elastic element 8, the step part 14 is opposite to the sliding block 6 to form a relatively closed space for accommodating the first elastic element 8, and when the sliding block 6 slides in the chute 7, the first elastic element 8 is elastically deformed with the movement of the sliding block 6 because the two ends of the first elastic element 8 are respectively installed in the first slot 15 and the second slot 16.

[0044] This design enables the first elastic element 8 to always remain in a relatively stable position and be closely connected with the sliding block 6, for example, when the sliding block 6 slides to the positioning seat 4, the first elastic element 8 is compressed and its elastic potential energy increases, and when the sliding block 6 is subjected to a reverse force, the first elastic element 8 pushes the sliding block 6 back to the initial position by using the stored elastic potential energy.

[0045] In the embodiment of the utility model, the mounting frame seat 3 comprises a mounting frame seat body 17 and a first connecting plate 18, the first connecting plate 18 is fixedly connected to the upper end face of the mounting frame seat body 17 and forms a sliding chamber 19 for limiting the movement of the moving seat 5 together with the mounting frame seat body 17, a socket 20 communicating with the sliding chamber 19 is arranged on the upper end face of the first connecting plate 18, and the socket 20 is correspondingly matched with the lower pressing block 10.

[0046] The mounting frame seat body 17 forms the chute 7 at the inner bottom of the sliding chamber 19, and one side of the mounting frame seat body 17 has an opening corresponding to the sliding chamber 19 to form a punch hole 21 for the punch 9 to slide through the opening.

[0047] The sliding cavity 19 formed by the mounting frame seat body 17 and the first connecting plate 18 provides a stable and limited movement space for the moving seat 5, and the moving seat 5 can only slide along the sliding cavity 19, so that the certainty and stability of the movement track are ensured; the insertion hole 20 formed in the upper end surface of the first connecting plate 18 is accurately matched with the downward pushing block 10, when the mold is closed, the downward pushing block 10 can be accurately inserted into the sliding cavity 19 through the insertion hole 20 and is in butt joint with the moving seat 5, so that the power transmitted by the downward pushing block 10 can be efficiently and accurately applied to the moving seat 5, and stable driving force is ensured to drive the punch 9 to perform the punching operation, and the principle is similar to that of a precise power transmission channel, so that the power of the upper mold seat 1 is accurately transmitted to the moving seat 5, and deviation and loss in the power transmission process are avoided.

[0048] The sliding groove 7 formed in the inner bottom of the mounting frame seat body 17 is tightly matched with the sliding block 6 at the lower end of the moving seat 5, further guides the sliding direction of the moving seat 5, and also provides support and limiting for the sliding block 6, the sliding of the sliding block 6 in the sliding groove 7 is the basis for the horizontal movement of the moving seat 5, and the design of the sliding groove 7 ensures the stability and linearity of the movement of the sliding block 6, and then ensures that the punch 9 can accurately perform lateral punching on the product;

[0049] The punch hole 21 formed in the side of the mounting frame seat body 17 corresponding to the opening of the sliding cavity 19 provides a punching channel for the punch 9, and the punch 9 is driven by the moving seat 5 to perform punching operation on the product placed on the positioning seat 4 through the punch hole 21, so that the punch 9 does not interfere with the mounting frame seat body 17 during the punching process, and the precision and quality of the punching are ensured.

[0050] In the embodiment of the utility model, the moving seat 5 includes the moving seat body 22 and the second connecting plate 23 fixedly connected to one side of the moving seat body 22, and the third slot 24 for installing the punch 9 is formed between the moving seat body 22 and the second connecting plate 23.

[0051] The lower end of the moving seat body 22 extends to form the sliding block 6.

[0052] The moving seat 5 is composed of the moving seat body 22 and the second connecting plate 23, and the third slot 24 formed between them is used for installing the punch 9, and this design is similar to a customized clamp, which provides a special installation position for the punch 9, and the punch 9 is installed in the third slot 24 and can be tightly connected with the moving seat 5, so that when the moving seat 5 is driven to slide by the downward pushing block 10, the punch 9 can move synchronously with the moving seat 5;

[0053] The third slot 24 is designed to make the punch 9 more stable, compared with simply fixing the punch 9 on the surface of the moving seat 5, the embedded installation can prevent the punch 9 from loosening or moving during the punching process, and the stable installation of the punch 9 can ensure the accuracy and quality of the punching, avoid the punching position error or the irregular punching shape caused by the position change of the punch 9, etc. When the punch 9 is worn or damaged due to long-term use, the design of the third slot 24 facilitates the disassembly and replacement of the punch 9, and the operator can relatively easily take out the old punch 9 from the third slot 24 (such as the moving seat body 22 and the second connecting plate 23 are fastened by screws), and install a new punch 9, without the need to make large-scale adjustment to the entire mold structure, which helps to reduce the mold maintenance time, improve the mold maintenance efficiency, and thus reduce the production cost.

[0054] In the utility model embodiment, the elastic pressing assembly 11 comprises a second elastic element 25, a pressing plate 26 and a guide rod 27, the lower end of the guide rod 27 penetrates the upper die holder 1 and is in sliding fit with the upper die holder 1, the lower end of the guide rod 27 is fixedly connected with the pressing plate 26, and the upper and lower ends of the second elastic element 25 are respectively installed on the upper die holder 1 and the pressing plate 26.

[0055] The guide rod 27 penetrates the upper die holder 1 and is in sliding fit with the upper die holder 1, which provides accurate guidance for the up-down movement of the pressing plate 26; when the mold is closed, along with the downward movement of the upper die holder 1, the guide rod 27 moves downward synchronously with the pressing plate 26, at this time, the second elastic element 25 installed between the upper die holder 1 and the pressing plate 26 is compressed and generates elastic potential energy;

[0056] The second elastic element 25 (such as a spring) plays a role in buffering and storing energy in the process; when the pressing plate 26 contacts the product placed on the positioning seat 4, along with the continuous downward movement of the upper die holder 1, the second elastic element 25 is further compressed, and the pressure applied by the pressing plate 26 to the product gradually increases; this pressure can firmly fix the product on the positioning seat 4 and prevent the product from moving due to lateral force during the punching process; this is achieved by utilizing the elastic deformation characteristics of the elastic element, according to the movement of the mold and the fixing requirements of the product, to realize stable pressing of the product.

[0057] In the utility model embodiment, the lower end of the pressing plate 26 is protrudingly formed with a pressing portion 28 corresponding to the positioning seat 4, the two sides of the pressing portion 28 are formed with a give-way slot 29 corresponding to the mounting frame seat 3, and the inner bottom of the give-way slot 29 is in limiting fit with the mounting frame seat 3.

[0058] The pressing part 28 protruding at the lower end of the pressing plate 26 is directly in contact with the product and applies pressure, and when the elastic pressing assembly 11 is in operation, the pressing part 28 concentrates and transmits the pressure to the product, so that the product is tightly attached to the positioning seat 4, and the shape and size of the pressing part 28 are designed according to the shape of the product and the structure of the positioning seat 4, so as to more effectively fix the product and ensure that the product does not displace during the punching process, and from the perspective of force distribution, the pressing part 28 can uniformly distribute the pressure generated by the second elastic element 25 to the key parts on the surface of the product, so as to ensure that the product maintains a stable position during the entire punching process.

[0059] The design of the yielding slot 29 is mainly to avoid interference between the pressing plate 26 and the mounting frame seat 3 during the closing of the mold, and since the mounting frame seat 3 is around the product in the mold structure, when the pressing plate 26 moves downward, space needs to be left for the mounting frame seat 3, and the yielding slot 29 plays this role, and at the same time, the inner bottom of the yielding slot 29 is limited in cooperation with the mounting frame seat 3, and this limiting action can further improve the stability of the entire mold during the closing process, and through the cooperation of the yielding slot 29 and the mounting frame seat 3, the downward position of the pressing plate 26 can be accurately controlled, so that the pressing part 28 of the pressing plate 26 can accurately act on the product, and the movement track of the elastic pressing assembly 11 as a whole is stable and predictable.

[0060] In the embodiment of the utility model, the lower end of the pressing part 28 is further connected with a flexible pad 30.

[0061] The flexible pad 30 is connected at the lower end of the pressing part 28, and when the pressing plate 26 moves downward to apply pressure to the product, the flexible pad 30 first contacts the product, and the flexible pad 30 can be regarded as a buffer layer, which can effectively buffer the pressure applied by the pressing plate 26, and since the material has certain elasticity and flexibility, the pressure can be more uniformly distributed on the surface of the product, for example, for some products with irregular surfaces or brittle materials, directly using a hard pressing part 28 may cause the pressure to concentrate in a local area, thereby damaging the product, and the flexible pad 30 can adaptively adjust according to the shape and undulation of the surface of the product, so that the pressure is uniformly transmitted to the product, and the product is ensured not to be damaged due to excessive local pressure during the fixing process.

[0062] Furthermore, when the flexible pad 30 contacts the surface of the product, friction will be generated, and this friction helps to better fix the product during the punching process and prevent the product from displacing due to lateral force, and at the same time, the material properties of the flexible pad 30 can avoid scratching or other forms of damage to the surface of the product.

[0063] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
