Description

Technical Field

[0001] This utility model relates to the field of mold processing equipment technology, specifically a buffer mechanism for a mold. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] Currently, existing stamping dies on the market often experience excessive downward stamping speeds during the stamping process, which can easily damage the die. As the number of stamping cycles accumulates, the stamping block will wear down. The buffer mechanism of the die typically consists of buffer springs at the four ends of the stamping block, with the stamping block and buffer springs connected to the stamping table via four guide posts. However, this device has certain drawbacks. When disassembling and replacing the buffer springs, it is necessary to remove the top plate of the stamping table and then pull the stamping block and the connected buffer springs out of the four guide posts. This design undoubtedly increases the difficulty of disassembly. Therefore, this utility model proposes a buffer mechanism for the die to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a buffer mechanism for a mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a buffer mechanism for a mold, including a processing table composed of two frame plates, and further including: four guide pillars connected to the upper and lower frame plates for guiding the stamping assembly; a driving assembly disposed on the processing table for driving the stamping assembly to move up and down; and a stamping assembly including a stamping block installed at the lower end of a support plate, the stamping block being adapted to a stamping groove on the processing table, the stamping block being connected through two sets of crossbeam plates, and buffer springs provided at the lower ends of the extensions at both ends of the two sets of crossbeam plates, the buffer springs being connected to the upper and lower connecting blocks, and the buffer springs being detachably installed at the lower end of the crossbeam plates via the upper connecting block, with a guide rod passing through between the buffer springs and the two connecting blocks.

[0006] Preferably, the drive assembly includes a cylinder mounted on the upper plate of the processing table. The cylinder is detachably connected to a support plate below the upper plate via a connecting plate at its output end. The support plate is connected through four guide posts.

[0007] Preferably, the outer diameter of the guide rod is adapted to the perforation on the stamping groove.

[0008] Preferably, the upper connecting block has a screw cavity at its center, the upper end of the guide rod has a thread, and the guide rod is helically mounted on the upper connecting block.

[0009] Preferably, one end of each of the two sets of crossbeams is provided with a positioning block, and the two sets of crossbeams are detachably mounted on the stamping block via the positioning block at one end.

[0010] Preferably, the four corners of the upper end of the stamping block are reserved with positioning holes, and the stamping block is detachably installed on the support plate by means of fixing bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By using a stamping assembly, the upper connecting block of the buffer spring can be detachably installed on the lower end of the crossbeam plate, and the guide rod is spirally installed with the upper connecting block. This facilitates the individual disassembly and replacement of the buffer spring and the guide rod. When the buffer spring experiences problems such as weakened elasticity, there is no need to replace the entire complex parts, thus reducing maintenance costs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a buffer mechanism for a mold, including a processing table 1, which is composed of two frame plates 11, and also includes: four guide pillars 2, which are connected to the upper and lower frame plates 11 and are used to guide the stamping assembly 4; a drive assembly 3, which is set on the processing table 1 and is used to drive the stamping assembly 4 to move up and down; the stamping assembly 4 includes a stamping block 41, which is installed at the lower end of the support plate 33 and is adapted to the stamping groove 12 on the processing table 1. The stamping block 41 is connected through two sets of crossbeam plates 43. The lower ends of the extensions at both ends of the two sets of crossbeam plates 43 are provided with buffer springs 45, which are connected to the upper and lower connecting blocks 46. The buffer springs 45 are detachably installed at the lower end of the crossbeam plates 43 through the upper connecting block 46. A guide rod 47 is provided between the buffer springs 45 and the two connecting blocks 46.

[0020] Please see Figures 1 to 4 The drive assembly 3 includes a cylinder 31 mounted on the upper plate 11 of the processing table 1. The cylinder 31 is detachably connected to the support plate 33 below the upper plate 11 via a connecting plate 32 at the output end. The support plate 33 is connected through four guide posts 2, which provide guidance for the movement of the support plate 33.

[0021] Please see Figures 1 to 4 The outer diameter of the guide rod 47 is adapted to the through hole 13 on the stamping groove 12. The buffer spring 45 is detachably installed at the lower end of the crossbeam plate 43 via the upper connecting block 46. During long-term use, the buffer spring 45 is a vulnerable part and may experience a weakening of elasticity. This detachable design allows the buffer spring 45 to be removed from the crossbeam plate 43 for individual replacement without disassembling the entire stamping assembly 4, thus greatly reducing maintenance costs and time.

[0022] Please see Figures 1 to 4 The upper connecting block 46 has a screw cavity in the center, and the upper end of the guide rod 47 has a thread 48. The guide rod 47 is installed on the upper connecting block 46 in a spiral manner.

[0023] Please see Figures 1 to 4 One end of each of the two sets of crossbeam plates 43 is provided with a positioning block 44. The two sets of crossbeam plates 43 are detachably mounted on the stamping block 41 through the positioning block 44 at one end. The four corners of the upper end of the stamping block 41 are reserved with positioning holes 42. The stamping block 41 is detachably mounted on the support plate 33 through fixing bolts.

[0024] Working steps: Start cylinder 31, which drives support plate 33 to move downward along four guide posts 2. When stamping block 41 contacts the part to be stamped, stamping begins. Since stamping block 41 is compatible with stamping groove 12 on processing table 1, the accuracy and stability of stamping can be guaranteed. During the downward stamping process of stamping block 41, a certain impact force will be generated. At this time, buffer spring 45 installed below both ends of crossbeam plate 43 begins to play its role. Buffer spring 45 is subjected to the impact force transmitted by stamping block 41 and undergoes elastic deformation to absorb the energy during stamping and reduce impact damage to other parts of the mold. At this time, guide rod 47 passes through buffer spring 45 and connecting block 46. Guide rod 47 is compatible with through hole 13 on stamping groove 12, which restricts the movement direction of buffer spring 45, making it more stable during the buffering process and preventing buffer spring 45 from shifting or twisting, thus ensuring the reliability of the buffering effect.

[0025] Disassembly steps: When it is necessary to disassemble the buffer spring 45, simply use a disassembly tool to remove the connecting block 46 at the upper end of the buffer spring 45 from the crossbeam plate 43. Then, since the thread 48 at the upper end of the guide rod 47 is helically connected to the central threaded cavity of the upper connecting block 46, simply rotate the guide rod 47 counterclockwise to unscrew it from the upper connecting block 46, thereby separating the buffer spring 45 from the guide rod 47. When it is necessary to disassemble the entire stamping assembly 4, since the four corners of the upper end of the stamping block 41 have reserved positioning holes 42, after the fixing bolt is removed, the stamping block 41 can be easily removed from the support plate 33. Then, by disassembling the connection between the positioning block 44 and the stamping block 41, the two sets of crossbeam plates 43 can be removed from the stamping block 41.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
