Description

Technical Field

[0001] This utility model belongs to the technical field of spring processing equipment, and specifically relates to a spring processing mold. Background Technology

[0002] Spring processing dies are specialized tools used to manufacture various types of springs, achieving spring forming and shaping through different structures and processes. They come in a variety of types, commonly including stamping dies, winding dies, and thermoforming dies. Stamping dies are used to produce leaf springs, shaping them through a stamping process; winding dies are mainly for helical springs, using rotational motion to wind metal wire into shape; thermoforming dies process metal materials at high temperatures and are suitable for large, high-strength springs. Die materials are mostly made of high-quality alloy steel, possessing high hardness, wear resistance, and toughness, ensuring durability and processing accuracy. With technological advancements, spring processing dies are continuously moving towards higher precision, automation, and intelligence. Utilizing advanced CNC technology and simulation, spring production efficiency and quality can be effectively improved, meeting the diverse needs of industries such as automotive, machinery, and electronics.

[0003] The announcement number "CN217512650U" discloses a spring processing mold, including a base, a support, and a processing assembly. The support is installed above the base. The processing assembly includes a template unit, a pushing unit, a first support plate, four support rods, a spring sheet, a second support plate, four first cylinders, and scrap. The template unit is installed above the support, and the pushing unit is installed on one side of the support. The two ends of the four support rods are respectively fixedly connected to the lower part of the first support plate and the upper part of the base. The four first cylinders are all installed above the base, and the output ends of the four first cylinders are all fixedly connected to the lower part of the second support plate. After the raw material is stamped by the pushing unit, the spring sheet and scrap are pushed away sequentially by the pushing unit, eliminating the need for manual removal and making it more convenient for users.

[0004] Although the aforementioned utility model uses a pushing unit to push away the spring sheet and scrap after the raw material is stamped, eliminating the need for manual removal and making it more convenient for users, the spring still needs to be removed from the mold manually or by other means after it is formed. This process is cumbersome and time-consuming, which reduces the degree of automation in production, slows down the overall production pace, and makes it impossible to achieve efficient continuous production. Moreover, manual removal can cause the spring to be subjected to uneven external force during demolding, resulting in defects such as deformation and scratches, affecting the dimensional accuracy and surface quality of the product, increasing the defect rate, and raising production costs. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a spring processing mold to solve the problem that after the spring is formed, it is necessary to manually or otherwise additionally remove the spring from the mold. This process is cumbersome and time-consuming, which will reduce the degree of automation of production, slow down the overall production rhythm, and make it impossible to achieve efficient continuous production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A spring processing mold includes a base and a stamping cover plate. The top of the base has an installation groove, and a mold body is movably connected inside the installation groove. The top of the mold body has mold holes symmetrically spaced at equal intervals. Fixing components are symmetrically installed inside the mold body. A demolding component is installed at the bottom of the base. A pressure groove is opened at the bottom of the stamping cover plate.

[0008] The demolding assembly includes a lifting plate, ejector pins, a first rotating pin, a second rotating pin, threaded holes, threaded rods, through holes, guide rods, and connecting blocks. The first and second rotating pins are symmetrically rotatably connected to the top of the base. The first rotating pin has a threaded hole at its top, with a threaded rod threaded inside. The second rotating pin has a through hole at its top, with a guide rod slidably connected inside. A connecting block is rotatably connected to the bottom of the guide rod and the threaded rod. The bottom of the connecting block is threadedly connected to the lifting plate. Ejector pins are symmetrically fixed at equal intervals on the top of the lifting plate, and the ejector pins are slidably connected to the mold hole. A transmission assembly is installed on the outside of the first rotating pin, eliminating the need for manual part removal, greatly reducing removal time, enabling continuous production, significantly improving spring processing efficiency, and avoiding problems such as deformation and scratches caused by uneven force on the springs. This effectively ensures the dimensional accuracy and surface quality of the springs, reduces the defect rate, and ensures product quality stability.

[0009] As a preferred technical solution, the transmission assembly includes a drive gear, a driven gear, and a knob. The driven gear is fixedly sleeved on the outer side of the first rotating column, and the drive gear is rotatably connected to the top of the base. A knob is fixedly connected to the center of the top of the drive gear. The drive gear and the driven gear mesh with each other. By rotating the knob, the rotation of the drive gear can be easily controlled, thereby driving the driven gear and the first rotating column to operate. There is no need for complicated operating procedures and tools, which reduces the difficulty of operation and allows operators to quickly and flexibly adjust the relevant functions of the mold, thereby improving work efficiency.

[0010] As a preferred technical solution, the base has symmetrically arranged movable holes on the top, and movable rods are symmetrically fixedly connected to the bottom of the stamping cover plate. The movable rods are slidably connected to the movable holes, and buffer springs are sleeved on the outside of the movable rods. The two ends of the buffer springs are fixedly connected to the top of the base and the bottom of the stamping cover plate, respectively. When the stamping cover plate is stamping, the buffer springs can effectively absorb the impact force generated during the stamping process. Through the compression and rebound of the springs, the impact force is converted into elastic potential energy and then slowly released, which greatly reduces the vibration and noise during stamping. This not only improves the comfort of the working environment, but also reduces the impact of vibration on other parts of the mold and ensures the stable operation of the mold.

[0011] As a preferred technical solution, the fixing component includes a cavity, a return spring, a moving plate, and a locking block. The mold body has symmetrically symmetrically formed cavities. A return spring is fixedly connected to one side of each cavity, and a moving plate is fixedly connected to the other end of the return spring. The moving plate is slidably connected to the cavity. A locking block is fixedly connected to the other side of the moving plate, extending outwards from the outside of the mold body. The bottom of the locking block has a slope. The mold body is inserted into the mounting groove. Locking grooves are formed on both sides of the mounting groove. The locking block engages with the locking grooves. An unlocking block is slidably connected inside the locking grooves. Guide grooves are formed on both sides of the locking grooves. Guide blocks are fixedly connected to both sides of the unlocking block. The guide grooves and guide blocks are slidably connected. No additional complex operating steps or special tools are required. Operators can install and fix the mold body simply by inserting it, greatly reducing the difficulty of operation. Furthermore, different molds can be quickly switched according to production needs, significantly improving production efficiency and meeting diverse production requirements.

[0012] In summary, the present invention has the following main advantages:

[0013] Firstly, in this utility model, after the stamping work is completed, the knob is turned to control the drive gear to drive the driven gear to rotate, thereby controlling the first rotating column to rotate. When the first rotating column rotates, it drives the threaded hole to rotate. The threaded hole and the threaded rod rotate in a threaded manner, thereby controlling the threaded rod to drive the lifting plate to rise. At the same time, the lifting plate drives the ejector column to rise. The ejector column slides inside the die hole and ejects the spring inside the die hole. This eliminates the need for manual part removal, greatly reduces part removal time, enables continuous production, significantly improves the production efficiency of spring processing, and avoids problems such as deformation and scratches caused by uneven force on the spring. It effectively ensures the dimensional accuracy and surface quality of the spring, reduces the defect rate, and ensures the stability of product quality.

[0014] Secondly, in this utility model, the mold body is inserted into the mounting groove of the base. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the moving plate to press against the return spring. The return spring is compressed, and the locking block retracts into the cavity. When the locking block moves to the locking groove, the return spring resets, the moving plate rebounds, and the locking block pops out. The locking block and the locking groove are locked together. No additional complicated operation steps or special tools are required. Operators can install and fix the mold body with a simple insertion action, which greatly reduces the difficulty of operation. Moreover, different molds can be quickly switched according to production needs, significantly improving production efficiency and meeting diverse production requirements.

A transmission assembly 11 is installed on the outside of the first rotating column 103. After the stamping work is completed, the knob 113 is turned to control the drive gear 111 to drive the driven gear 112 to rotate, thereby controlling the first rotating column 103 to rotate. When the first rotating column 103 rotates, it drives the threaded hole 105 to rotate. The threaded hole 105 and the threaded rod 106 rotate in a threaded manner, thereby controlling the threaded rod 106 to drive the lifting plate 101 to rise. At the same time, the lifting plate 101 drives the ejector columns 102 to rise. The ejector columns 102 slide inside the die hole 4 and eject the spring inside the die hole 4.

[0024] refer to Figure 2 The transmission assembly 11 includes a drive gear 111, a driven gear 112, and a knob 113. The driven gear 112 is fixedly sleeved on the outside of the first rotating column 103. The drive gear 111 is rotatably connected to the top of the base 1. The knob 113 is fixedly connected to the center of the top of the drive gear 111. The drive gear 111 and the driven gear 112 mesh with each other. Rotating the knob 113 controls the drive gear 111 to rotate. The drive gear 111 meshes with the driven gear 112, thereby controlling the driven gear 112 to rotate. The driven gear 112 drives the first rotating column 103 to rotate.

[0025] refer to Figure 5The base 1 has symmetrically arranged movable holes 5 on its top, and the bottom of the stamping cover plate 8 is symmetrically fixedly connected with movable rods 6. The movable rods 6 and the movable holes 5 are slidably connected. A buffer spring 7 is sleeved on the outside of the movable rod 6. The two ends of the buffer spring 7 are fixedly connected to the top of the base 1 and the bottom of the stamping cover plate 8, respectively. When the stamping cover plate 8 descends, the stamping cover plate 8 drives the movable rods 6 to slide inside the movable holes 5. At the same time, the stamping cover plate 8 presses against the base 1, and the buffer spring 7 is compressed.

[0026] refer to Figure 4 The fixing component 12 includes a cavity 121, a return spring 122, a moving plate 123, and a locking block 124. The mold body 3 has symmetrically arranged cavities 121 inside. A return spring 122 is fixedly connected to one side of the cavity 121, and a moving plate 123 is fixedly connected to the other end of the return spring 122. The moving plate 123 is slidably connected to the cavity 121. A locking block 124 is fixedly connected to the other side of the moving plate 123, extending beyond the outer side of the mold body 3. The bottom of the locking block 124 has a slope. The mold body 3 is inserted into the mounting groove 2. Locking grooves 13 are provided on both sides. The locking block 124 is snapped into the locking groove 13. The mold body 3 is inserted into the mounting groove 2 of the base 1. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 124, causing the locking block 124 to drive the moving plate 123 to press against the return spring 122. The return spring 122 is compressed, and the locking block 124 retracts into the cavity 121. When the locking block 124 moves to the locking groove 13, the return spring 122 resets, and the moving plate 123 rebounds, causing the locking block 124 to pop out. The locking block 124 is then snapped into the locking groove 13 and fixed.

[0027] refer to Figure 4 An unlocking block 14 is slidably connected inside the locking groove 13. Guide grooves 16 are provided on both sides of the locking groove 13. Guide blocks 15 are fixedly connected to both sides of the unlocking block 14. The guide grooves 16 and guide blocks 15 are slidably connected. Pushing the unlocking block 14 causes it to slide inside the locking groove 13. The unlocking block 14 drives the guide blocks 15 to slide inside the guide grooves 16. The unlocking block 14 pushes the locking block 124, causing the locking block 124 to drive the moving plate 123 to press against the return spring 122. The return spring 122 is compressed, and the locking block 124 retracts into the cavity 121. The locking block 124 and the locking groove 13 are no longer engaged.

[0028] Operating principle and advantages: First, the mold body 3 is inserted into the mounting groove 2 of the base 1. During insertion, the squeezing force applies pressure to the inclined surface of the locking block 124, causing the locking block 124 to drive the moving plate 123 to press against the return spring 122. The return spring 122 is compressed, and the locking block 124 retracts into the cavity 121. When the locking block 124 moves to the locking groove 13, the return spring 122 resets, and the moving plate 123 rebounds, causing the locking block 124 to pop out. The locking block 124 is then locked and fixed in place with the locking groove 13. The springs are then sequentially placed into the mold body... Inside the die hole 4 on body 3, stamping is performed by the stamping cover plate 8. After the stamping is completed, the knob 113 is turned to control the drive gear 111 to drive the driven gear 112 to rotate, thereby controlling the first rotating column 103 to rotate. When the first rotating column 103 rotates, it drives the threaded hole 105 to rotate. The threaded hole 105 and the threaded rod 106 rotate in a threaded manner, thereby controlling the threaded rod 106 to drive the lifting plate 101 to rise. At the same time, the lifting plate 101 drives the ejector column 102 to rise. The ejector column 102 slides inside the die hole 4 and ejects the spring inside the die hole 4.

[0029] This invention eliminates the need for manual part handling, greatly reducing part handling time, enabling continuous production, significantly improving the production efficiency of spring processing, and avoiding problems such as deformation and scratches caused by uneven force on the springs. It effectively ensures the dimensional accuracy and surface quality of the springs, reduces the defect rate, and ensures the stability of product quality.
