Description

Technical Field

[0001] This utility model belongs to the technical field of metal stamping dies, specifically relating to a riveting die for a snap-on spring sleeve. Background Technology

[0002] Clip-on spring sleeves, as connecting elements with elastic fastening functions, are widely used in automotive parts, home appliances, electronic equipment, and other fields. They mainly consist of a sleeve base, a cover, a latch, and a spring. The spring and latch are placed in the sleeve base, the cover is riveted to the opening of the sleeve base, and the latch, under the action of the spring, extends beyond the cover. Through its elastic snap-on structure, it engages with the mating component, enabling quick assembly and detachable fixed connection between components. To ensure the reliability of the clip-on spring sleeve, the riveting requirements are high. In existing technologies, the riveting process of snap-fit ​​spring sleeves typically requires manual assistance. Before riveting, the operator visually determines the installation position between the sleeve base and the cover. Then, using tools such as pliers, the operator manually presses the sleeve base and cover together. Subsequently, the stamping device is activated, causing the upper die to descend. Through the interaction of the upper and lower dies, pressure is applied to the predetermined part of the snap-fit ​​spring sleeve, completing the riveting connection between the sleeve base and the cover. The problem is that, using the above riveting process, the operator must keep their hands continuously close to the moving area of ​​the die during the riveting process. To maintain continuous pressure on the sleeve and cover to prevent the spring, cover, and latch from popping out of the sleeve, operational errors or equipment malfunctions can easily lead to accidental crushing injuries to operators, increasing the safety risks during the production of snap-fit ​​spring sleeves. Furthermore, using the above riveting process requires operators to rely on visual judgment and manually adjust the installation position between the sleeve and cover, which takes a significant amount of time. Therefore, only a small number of snap-fit ​​spring sleeves can be riveted within a certain timeframe, failing to meet the capacity requirements of mass production and thus restricting the overall production efficiency of snap-fit ​​spring sleeves.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome at least one of the shortcomings of the prior art and to provide a riveting mold for snap-fit ​​spring sleeves, which can prevent the snap-fit ​​spring sleeve accessories from popping out without relying on continuous manual pressing, avoid the operator's hands from approaching the moving area of ​​the mold during riveting, and reduce the safety risks during the production of snap-fit ​​spring sleeves.

[0005] To achieve the above objectives, the technical solution provided by this utility model embodiment is as follows: A riveting mold for a snap-fit ​​spring sleeve includes: The lower mold assembly includes a lower mold base, a lower module and a lower template disposed on the lower mold base, a riveting die and a component positioning hole disposed on the lower module, and a riveting punch disposed on the lower template and corresponding to the riveting die. The component positioning hole is disposed on the top surface of the lower module, and the bottom surface of the riveting punch is provided with a clearance groove for avoiding the latching spring sleeve tongue. The opening of the clearance groove faces the lower part and / or the front part of the riveting punch. The upper mold assembly includes an upper mold base and an upward push module disposed on the upper mold base; The upper mold assembly and the lower mold assembly are arranged in a vertically corresponding manner. When the snap-on spring sleeve is placed on the riveting mold, the snap-on spring sleeve is placed in the component positioning hole and abuts against the clearance groove. When the upper mold assembly and the lower mold assembly cooperate with each other, the upper push module moves downward and pushes the lower template to move downward, so that the riveting punch and the riveting die cooperate and rivet the snap-on spring sleeve.

[0006] The lower mold assembly also includes lower mold inserts. Two lower mold inserts are disposed on the lower module and are positioned opposite each other on the left and right sides of the component positioning hole. The two lower mold inserts together form a riveting die.

[0007] A sliding structure is provided between the lower module and the lower mold base, which allows the lower module to slide back and forth relative to the lower mold base in the front-to-back direction. The sliding structure includes a slide block and a slide groove. The slide block is disposed on the top surface of the lower mold base and extends along the front-back direction of the lower mold base. There are two slide blocks, which are disposed opposite each other on the left and right sides of the lower module. The slide groove is disposed on the side wall of the lower module and corresponds to the track end of the slide block. When the lower module is placed on the lower mold base, the slide groove is sleeved around the track end of the slide block and slides back and forth along the length direction of the slide block, so that the lower module slides back and forth relative to the lower mold base in the front-back direction.

[0008] The lower mold assembly also includes a limiting block, which is disposed on the top surface of the lower mold base and located on the rear side of the lower module. The limiting block restricts the lower module from continuing to slide backward and makes the riveting punch and riveting die correspond vertically.

[0009] An elastic locking structure is provided between the lower module and the lower mold base, which locks the lower module onto the lower mold base. The elastic locking structure includes a locking hole and an elastic locking shaft. The locking hole is located on the lower module and on the bottom surface of the lower module. The elastic locking shaft is located on the lower mold base and its movable end extends upward out of the top surface of the lower mold base and corresponds to the locking hole. When the lower module slides relative to the lower mold base, the movable end of the elastic locking shaft extends into the locking hole, so that the lower module is locked on the lower mold base.

[0010] A reset connection structure is provided between the lower template and the lower mold base. The reset connection structure allows the lower template to be slidably installed on the lower mold base and reset upward relative to the lower mold base. The reset connection structure includes a reset connection hole, a reset connection component, and a first reset component. The reset connection hole is disposed on the lower template, and the reset connection component is disposed on the top surface of the lower mold base and corresponds to the reset connection hole. The diameter of the reset connection hole is larger than the diameter of the shaft portion of the reset connection component and smaller than the diameter of the upper end portion of the reset connection component. The first reset component is sleeved around the reset connection component and located between the lower template and the lower mold base. When the lower template is disposed on the lower mold base, the reset connection component passes through the reset connection hole from top to bottom and is fixedly connected to the lower mold base, so that the lower template is installed on the lower mold base and slides back and forth along the height direction. When the upper mold assembly and the lower mold assembly are separated from each other, the rebound force of the first reset component causes the lower template to reset upward relative to the lower mold base.

[0011] A guide structure is also provided between the lower template and the lower mold base, which guides the lower template to move along the vertical direction of the lower mold base. The guiding structure includes guide holes and guide pillars. There are two guide holes, which are arranged opposite each other on the left and right ends of the lower template. The guide pillars are arranged vertically on the top surface of the lower mold base and correspond to the guide holes. The lower template is set on the lower mold base. The guide holes are sleeved around the guide pillars and move along the length of the guide pillars, so that the lower template moves in the up and down direction of the lower mold base.

[0012] The lower mold assembly also includes a component unloading structure, which is disposed on the lower module and facilitates the unloading of the snap-on spring sleeve from the lower mold assembly. The component unloading structure includes an unloading fixing block, an unloading slider, and a second reset component. The unloading fixing block is located at the bottom of the component positioning hole, and the unloading slider is slidably disposed in the component positioning hole and located above the unloading fixing block. The second reset component is disposed between the unloading fixing block and the unloading slider. When the upper mold assembly and the lower mold assembly are separated from each other, the rebound force of the second reset component causes the unloading slider to reset upward relative to the unloading fixing block, so that the snap-on spring sleeve can unload from the lower mold assembly.

[0013] A discharge limiting structure is provided between the discharge slider and the lower module to restrict the discharge slider from continuing to slide upward relative to the lower module. The unloading limiting structure includes a first limiting step and a second limiting step. The first limiting step is disposed on the lower module and located on the inner wall of the component positioning hole. The second limiting step is disposed on the unloading slider and located on the outer wall of the unloading slider. When the unloading slider slides upward relative to the lower module, the first limiting step and the second limiting step abut against each other to limit the unloading slider from continuing to slide upward.

[0014] A buffer structure is provided between the upper mold assembly and the lower mold assembly. The buffer structure includes a first buffer component and a second buffer component. The first buffer component is disposed on the bottom surface of the upper mold base, and the second buffer component is disposed on the top surface of the lower mold base. When the upper mold assembly and the lower mold assembly cooperate with each other, the first buffer component and the second buffer component abut against each other. The first buffer component is made of rubber or polyurethane material, and the second buffer component is made of rubber, polyurethane, or metal material.

[0015] The beneficial effects of this utility model are as follows: This utility model, through the riveting mold employing the above-mentioned technical solution, ensures that when the snap-fit ​​spring sleeve is placed on the riveting mold, the lower part of the snap-fit ​​spring sleeve is positioned within the component positioning hole, thus positioning the snap-fit ​​spring sleeve on the lower mold assembly. The snap-fit ​​spring sleeve's latch abuts against the clearance groove, preventing the snap-fit ​​spring sleeve's components from popping outwards without relying on continuous manual pressing. This avoids the operator's hands approaching the mold's moving area during snap-fit ​​spring sleeve riveting, preventing accidental crushing injuries to operators due to operational errors or equipment malfunctions, and reducing safety risks during snap-fit ​​spring sleeve production.

[0016] By using the riveting mold with the above technical solution, operators can quickly position the snap-fit ​​spring sleeves in the mold after assembly, reducing the adjustment time for the installation position of the snap-fit ​​spring sleeves, improving the riveting speed of the snap-fit ​​spring sleeves, and improving the overall production efficiency of the snap-fit ​​spring sleeves.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] See Figure 1-10 The riveting mold for this snap-fit ​​spring sleeve includes an upper mold assembly and a lower mold assembly arranged vertically and vertically. In this embodiment, the lower mold assembly includes a lower mold base 11, a lower module 12, a lower template 13, a riveting die 14, a component positioning hole 15, and a riveting punch 16. The upper mold assembly includes an upper mold base 21 and an upward push module 22. The snap-fit ​​spring sleeve 3 is a snap-fit ​​spring sleeve 3. Specifically, the lower module 12 is fixed to the top surface of the lower mold base 11 by fasteners. The lower template 13 can slide vertically above the lower mold base 11. The riveting die 14 is inserted into the lower module 12. The component positioning hole 15 is provided on the lower module 12, and its central axis coincides with the central axis of the riveting die 14. The riveting punch 16 is integrally formed on the bottom surface of the lower template 13. The bottom surface of the riveting punch 16 is provided with a relief groove 17. The opening of the relief groove 17 faces the lower and front of the riveting punch 16. When the snap-fit ​​spring sleeve 3 is placed on the riveting mold, The clearance groove 17 can avoid the latch tongue of the snap spring sleeve 3. The push module 22 is fixed to the bottom surface of the upper mold base 21 by fasteners. When the snap spring sleeve 3 is placed on the riveting mold, the lower part of the snap spring sleeve 3 is inserted into the component positioning hole 15. The latch tongue of the snap spring sleeve 3 extends into the clearance groove 17 and abuts against the inner top surface of the clearance groove 17. Therefore, the snap spring sleeve 3 can prevent the accessories of the snap spring sleeve 3 from popping out without manual intervention. This avoids the operator's hands from approaching the moving area of ​​the mold when the snap spring sleeve 3 is riveted, and prevents accidental crushing accidents caused by operator errors or equipment failures. It also reduces the safety risks during the production of the snap spring sleeve 3. When the upper mold assembly and the lower mold assembly cooperate with each other, the push module 22 moves downward and pushes the lower template 13 downward, so that the riveting punch 16 and the riveting die 14 cooperate and act on the snap spring sleeve 3 to realize the riveting of the snap spring sleeve 3.

[0029] By using the riveting mold with the above technical solution, the operator can quickly position the snap spring sleeve 3 in the mold after assembling it, reducing the adjustment time for the installation position of the snap spring sleeve 3, improving the riveting speed of the snap spring sleeve 3, and improving the overall production efficiency of the snap spring sleeve 3.

[0030] Furthermore, the lower mold assembly also includes a lower mold insert 141. Specifically, in this embodiment, the lower mold insert 141 is inserted into the lower module 12. The number of lower mold inserts 141 is preferably two, which are arranged opposite to each other on the left and right sides of the component positioning hole 15 and together form the riveting die 14. Through the above split design, high hardness materials can be used for the wear-prone areas of the riveting die 14, thereby ensuring the strength of the lower mold assembly while reducing material costs. In addition, when the lower mold insert 141 is damaged, it only needs to be replaced individually, without replacing the entire lower module 12, which reduces the maintenance cost of the riveting mold. The lower mold inserts 141 are symmetrically distributed on the left and right sides of the component positioning hole 15, which allows the riveting force to be evenly applied to the left and right sides of the snap spring sleeve 3, avoiding the riveting position shift caused by unilateral force or the stamping deformation of the snap spring sleeve 3. This is understood by those skilled in the art.

[0031] Furthermore, a sliding structure is provided between the lower module 12 and the lower mold base 11. Specifically, in this embodiment, the sliding structure includes a slide rail block 111 and a slide groove 121. The slide rail block 111 is fixed to the top surface of the lower mold base 11 by fasteners and extends along the front-rear direction of the lower mold base 11. Preferably, there are two slide rail blocks 111, which are arranged opposite to each other on the left and right sides of the lower module 12. The slide groove 121 is integrally formed on the side wall of the lower module 12. Preferably, there are two slide grooves 121, which are located on the left and right side walls of the lower module 12 and correspond to the track ends of the slide rail blocks 111. When the lower module 12 is placed on the lower mold base 11, the slide groove 121 moves from front to back. The lower module 12 is fitted around the track end of the slide block 111 and slides back and forth along the length of the slide block 111, allowing the lower module 12 to slide back and forth relative to the lower mold base 11 in the front-to-back direction. Through the above technical solution, when the lower module 12 slides forward relative to the lower mold base 11, it is convenient for the operator to place the snap-on spring sleeve 3 on the riveting mold. When the lower module 13 slides backward relative to the lower mold base 11, the riveting punch 16 and the riveting die 14 correspond to perform riveting processing on the snap-on spring sleeve 3, which improves the speed at which the snap-on spring sleeve 3 is placed on the riveting mold and further improves the overall production efficiency of the snap-on spring sleeve 3. This is something that those skilled in the art can understand.

[0032] Furthermore, the lower mold assembly also includes a limiting block 18. Specifically, in this embodiment, the limiting block 18 is fixed to the top surface of the lower mold base 11 by fasteners and is located on the rear side of the lower module 12. When the lower mold plate 13 slides backward relative to the lower mold base 11, the limiting block 18 can restrict the lower module 12 from continuing to slide backward. Through the above technical solution, when the lower mold plate 13 slides to the preset position, the limiting block 18 abuts against the lower module 12, forcibly stopping the lower module 12 from sliding. This ensures that the riveting punch 16 and the riveting die 14 are accurately aligned, avoiding the riveting position deviation caused by excessive sliding. Moreover, the limiting block 18 can prevent the lower module 12 from sliding excessively due to operator misoperation, thereby protecting the mold structure and the safety of the snap-on spring sleeve 3. This is understood by those skilled in the art.

[0033] Furthermore, an elastic locking structure is provided between the lower module 12 and the lower mold base 11. Specifically, in this embodiment, the elastic locking structure includes a locking hole 122 and an elastic locking shaft 112. The locking hole 122 is integrally formed on the bottom surface of the lower module 12. The elastic locking shaft 112 is fixedly mounted on the lower mold base 11 by a fastening structure. The movable end of the elastic locking shaft 112 extends upward beyond the top surface of the lower mold base 11 and corresponds to the locking hole 122. The end of the movable end of the elastic locking shaft 112 is spherical so that the movable end of the elastic locking shaft 112 can slide out of the locking hole 122, preventing the elastic locking shaft 112 from getting stuck in the locking hole 122. When the lower module 12 slides relative to the lower mold base 11... When in motion, the movable end of the elastic locking shaft 112 extends into the locking hole 122, locking the lower module 12 onto the lower mold base 11. Through the above technical solution, the lower module 12 automatically locks onto the lower mold base 11 after sliding into place. When the riveting mold is working, the elastic locking shaft 112 keeps the lower module 12 fixed by the spring preload, avoiding positional displacement caused by vibration or impact. Moreover, the operator only needs to apply external force forward to the lower module 12 to compress the spring of the elastic locking shaft 112, causing the elastic locking shaft 112 to exit the locking hole 122, realizing the quick unlocking of the lower module 12. This makes it easy for the operator to quickly pull out the lower module 12 and place the buckle spring sleeve 3, which can be understood by those skilled in the art.

[0034] Furthermore, the lower module 12 is provided with a handle 127, which is fixed to the front side wall of the lower module 12 by fasteners. The operator can easily push and pull the lower module 12 through the handle 127, so that the lower module 12 can slide back and forth relative to the lower mold base 11 in the front and back direction, which can be understood by those skilled in the art.

[0035] Furthermore, a reset connection structure is provided between the lower template 13 and the lower mold base 11. Specifically, in this embodiment, the reset connection structure includes a reset connection hole 131, a reset connection component 113, and a first reset component 114. The reset connection hole 131 is integrally formed on the lower template 13. Preferably, there are two reset connection holes 131, which are arranged opposite to each other on the left and right sides of the riveting punch 16. The reset connection component 113 is preferably a screw and fixed to the top surface of the lower mold base 11 through a threaded connection structure. Preferably, there are two reset connection components 113, which correspond to the reset connection holes 131. The diameter of the reset connection hole 131 is larger than the diameter of the shaft portion of the reset connection component 113, so that the lower template 13 slides along the length direction of the reset connection component 113. The diameter of the reset connection hole 131 is smaller than the diameter of the upper end of the reset connection component 113, so as to restrict the reset connection hole 131 from disengaging upward from the reset connection. Component 113, the first reset component 114 is preferably a spring and is sleeved around the reset connecting component 113 and located between the lower template 13 and the lower mold base 11. When the lower template 13 is set on the lower mold base 11, the reset connecting component 113 passes through the reset connecting hole 131 from top to bottom and is fixed to the lower mold base 11, so that the lower template 13 is installed on the lower mold base 11 and slides back and forth along the height direction. When the upper mold assembly and the lower mold assembly are separated from each other, the rebound force of the first reset component 114 makes the lower template 13 reset upward relative to the lower mold base 11. Through the above technical solution, the lower template 13 is prevented from getting stuck due to riveting force residue or oil stains, and the lower template 13 returns to the initial position after each riveting. The elastic deformation of the first reset component 114 can absorb part of the impact force, reduce the rigid collision between the lower template 13 and the lower mold base 11, and protect the structure of the riveting mold, which can be understood by those skilled in the art.

[0036] Furthermore, a guide structure is provided between the lower template 13 and the lower mold base 11. Specifically, in this embodiment, the guide structure includes guide holes 132 and guide posts 115. Preferably, there are two guide holes 132, which are arranged opposite to each other on the left and right ends of the lower template 13. The guide posts 115 are arranged vertically and fixed to the top surface of the lower mold base 11 by fixing blocks. Preferably, there are two guide posts 115, which correspond to the guide holes 132. When the lower template 13 is placed on the lower mold base 11, the guide holes 132 are sleeved around the guide posts 115 and move along the length of the guide posts 115, so that the lower template 13 is guided to move up and down along the lower mold base 11. Through the above technical solution, the cooperation between the guide posts 115 and the guide holes 132 can limit the lateral displacement of the lower template 13 during up and down movement, ensure the coaxiality of the riveting punch 16 and the riveting die 14, and ensure the mechanical performance of the riveting mold. This is understandable to those skilled in the art.

[0037] Furthermore, the lower module 12 is provided with a component unloading structure. Specifically, in this embodiment, the component unloading structure includes an unloading fixing block 123, an unloading slider 124, and a second reset component 125. The unloading fixing block 123 is fixedly mounted to the bottom of the component positioning hole 15 by a fixing structure. The unloading slider 124 can slide up and down in the component positioning hole 15 and is located above the unloading fixing block 123. The second reset component 125 is preferably a pressure spring and is disposed between the unloading fixing block 123 and the unloading slider 124. When the snap-on spring sleeve 3 is placed on the riveting mold, the lower part of the snap-on spring sleeve 3 abuts against the top surface of the unloading slider 124. When the upper mold assembly and the lower mold assembly cooperate with each other, the snap-on spring sleeve... 3. The unloading slider 124 is pushed downward by the pressure, and the unloading slider 124 overcomes the rebound force of the second reset component 125 and moves downward. When the upper mold assembly and the lower mold assembly are separated, the rebound force of the second reset component 125 causes the unloading slider 124 to be reset upward relative to the unloading fixing block 123, so that the snap-on spring sleeve 3 can be unloaded from the lower mold assembly. Through the above technical solution, the unloading slider 124 pops upward under the action of the second reset component 125 when the upper mold assembly and the lower mold assembly are separated, and pushes the snap-on spring sleeve 3 out of the component positioning hole 15. No manual intervention is required, which further improves the overall production efficiency of the snap-on spring sleeve 3. This can be understood by those skilled in the art.

[0038] Furthermore, an unloading limiting structure is provided between the unloading slider 124 and the lower module 12. Specifically, in this embodiment, the unloading limiting structure includes a first limiting step 126 and a second limiting step 1241. The first limiting step 126 is annular and integrally formed on the lower module 12 and located on the inner wall of the component positioning hole 15. The second limiting step 1241 is annular and integrally formed on the unloading slider 124 and located on the outer wall of the unloading slider 124. When the unloading slider 124 slides upward relative to the lower module 12, the first limiting step 126 and the second limiting step abut against each other to limit the unloading slider 124 from continuing to slide upward. Through the above technical solution, the unloading slider 124 is prevented from being excessively ejected, which could cause structural damage to the mold. At the same time, it ensures that the snap-on spring sleeve 3 is completely ejected but does not detach from the mold, which facilitates the removal operation of the snap-on spring sleeve 3 and ensures the consistency of each unloading stroke, avoiding unloading failure due to stroke fluctuation. This is understandable to those skilled in the art.

[0039] Furthermore, a buffer structure is provided between the upper mold assembly and the lower mold assembly. Specifically, in this embodiment, the buffer structure includes a first buffer component 211 and a second buffer component 116. The first buffer component 211 is preferably made of polyurethane material and is fixed to the bottom surface of the upper mold base 21 by fastening components. The second buffer component 116 is preferably made of polyurethane material and is fixed to the top surface of the lower mold base 11 by fastening components. When the upper mold assembly and the lower mold assembly cooperate with each other, the first buffer component 211 and the second buffer component 116 abut against each other. Through the above technical solution, the impact force generated by the mold during the riveting process can be absorbed, the energy generated by vibration can be effectively attenuated, and the noise generated during the riveting process can be reduced. This is understandable to those skilled in the art.

[0040] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
