Description

Technical Field

[0001] This invention relates to the field of molding die technology, specifically to a die stamping device. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. 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 undergo plastic deformation, thereby obtaining the desired parts.

[0003] Most of the molding dies widely used in the market adopt an integrated design, which involves pouring material into the mold and pressing it with an external hydraulic press. However, when used in small factories, it is necessary to frequently change the type of mold because it is necessary to process stamped parts of different shapes. Most of the existing installation methods require the use of external tools to install or disassemble the mold, which takes a long time. Therefore, we propose a mold stamping device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a die stamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a die stamping device, including an operating table, a control switch, a fixed bracket, and a hydraulic press installed outside the operating table. A mounting base is provided at the lower end of the fixed bracket, and a forming die is provided above the mounting base. An installation guide groove is provided on the mounting base. Guide bars are installed at the bottom of each forming die, and the guide bars can be inserted into the installation guide groove. Insertion ports are provided on both sides of the forming die, and retaining seats are movably inserted into each insertion port. Guide posts are installed in the retaining seats, and connecting brackets are sleeved around the guide posts. A positioning post is provided at the bottom of the connecting bracket, and a handle is provided at the top of the connecting bracket. A positioning hole is provided inside the bottom end of the installation guide groove, and the bottom end of the positioning post can be inserted into the positioning hole.

[0006] As a further preferred embodiment of this technical solution, the guide posts are configured in two sets, both sets of guide posts are fixed inside the positioning sleeve on both sides, and the connecting bracket is sleeved on the outside of the two sets of guide posts.

[0007] As a further preferred embodiment of this technical solution, a return spring is wound around the outside of the guide post, and the two ends of the return spring are respectively connected to the inner wall of the positioning sleeve and the outer wall of the connecting bracket. The connecting bracket is elastically connected to the positioning sleeve through the return spring.

[0008] As a further preferred embodiment of this technical solution, the cross-section of the mounting guide groove is T-shaped, and the cross-section of the guide strip is T-shaped corresponding to the mounting guide groove.

[0009] As a further preferred embodiment of this technical solution, the connecting bracket has storage slots on both sides, and a rotating rod is rotatably connected in each storage slot. A pull handle is provided on the outside of each rotating rod, and auxiliary slots are provided on both sides of the positioning sleeve.

[0010] As a further preferred embodiment of this technical solution, both sets of rotating rods can be rotated into the auxiliary slot and can be completely retracted into the storage slot on the connecting bracket.

[0011] This invention provides a die stamping device, which has the following advantages: 1. This invention features pluggable retainers on both sides of the molding die. First, the molding die, along with guide bars, is inserted into the mounting guide groove on the mounting base and moved to the center of the mounting base. Then, the positioning pin inside the retainer is inserted into the positioning hole at the bottom of the mounting guide groove, quickly and completely positioning and installing the molding die. When disassembling the molding die, the handle is pulled upwards, causing the connecting bracket to move upwards along the guide pin under the force of the handle. This quickly releases the lateral limiting effect on the molding die, allowing the molding die to be pushed laterally. The molding die then slides outwards along the mounting guide groove, quickly completing the disassembly of the molding die. The entire process requires no external auxiliary tools, is simple to operate, and greatly improves the speed of molding die replacement.

[0012] 2. This invention utilizes the interplay of a positioning sleeve, connecting bracket, storage groove, rotating rod, pull handle, and auxiliary slots. When disassembling the molding die, pulling upwards causes the connecting bracket to move the rotating rod to the auxiliary slots. At this point, the positioning pin has completely released its limiting effect on the molding die. Pulling the pull handle then allows the rotating rod to rotate and unfold within the storage groove, enabling it to rotate into the auxiliary slots on both sides of the positioning sleeve. The rotating rod then exerts a downward limiting effect on the connecting bracket, effectively preventing the positioning pin from moving during the process and avoiding contact between the positioning pin and the installation guide groove. This further improves the ease of loading and unloading the molding die. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] This invention provides a technical solution: such as Figure 1 and Figure 6 As shown, in this embodiment, a die stamping device includes an operating table 1, a control switch 2, a fixed bracket 3, and a hydraulic press 4 installed outside the operating table 1. A mounting base 5 is provided at the lower end of the fixed bracket 3, and a forming die 6 is provided above the mounting base 5. A mounting guide groove 7 is provided on the mounting base 5. Guide bars 8 are installed at the bottom of each forming die 6, and the guide bars 8 can be inserted into the mounting guide groove 7. Insertions 9 are provided on both sides of the forming die 6, and a retainer 10 is movably inserted into each insertion 9. A guide post 12 is installed inside the retainer 10. A connecting bracket 13 is sleeved on the outside of the guide post 12. A positioning post 14 is provided at the bottom of the connecting bracket 13, and a handle 15 is provided at the top of the connecting bracket 13. A positioning hole 16 is provided inside the bottom of the mounting guide groove 7, and the bottom end of the positioning post 14 can be inserted into the positioning hole 16. Two sets of guide posts 12 are provided, and both sets of guide posts 12 are fixed. The connecting bracket 13 is fitted inside the positioning sleeve 11 on both sides and is sleeved on the outside of the two sets of guide posts 12. This design allows the connecting bracket 13 to move smoothly up and down along the two sets of guide posts 12, ensuring that both ends of the connecting bracket 13 are on the same horizontal line, thus improving the stability of the connecting bracket 13 when moving. The guide posts 12 are wrapped with a return spring 17. The two ends of the return spring 17 are respectively connected to the inner wall of the positioning sleeve 11 and the outer wall of the connecting bracket 13. The connecting bracket 13 forms an elastic connection with the positioning sleeve 11 through the return spring 17. Through this design, the connecting bracket 13 can be subjected to the continuous downward elastic force of the return spring 17, allowing the connecting bracket 13 to drive the positioning post 14 to quickly enter the positioning hole 16 at the bottom of the installation guide groove 7. At the same time, it prevents the positioning post 14 from accidentally leaving the positioning hole 16 due to vibration generated by machine operation, thus ensuring the normal use of the positioning post 14.

[0017] like Figure 3 and Figure 4 As shown, the cross-section of the mounting guide groove 7 is T-shaped, and the cross-section of the guide bar 8 is T-shaped corresponding to that of the mounting guide groove 7. With this design, when the guide bar 8 is inserted into the mounting guide groove 7 under the drive of the forming mold 6, the mounting guide groove 7 can restrict the vertical movement of the guide bar 8, and at the same time, it can prevent the forming mold 6 from shaking during processing and use, thus improving the stability of the forming mold 6 during use.

[0018] like Figure 3 and Figure 6 As shown, storage slots 18 are provided on both sides of the connecting bracket 13, and rotating rods 19 are rotatably connected in the storage slots 18. Pull handles 20 are provided on the outside of the rotating rods 19. Auxiliary slots 21 are provided on both sides of the positioning sleeve 11. Both sets of rotating rods 19 can rotate into the auxiliary slots 21 and can be completely stored in the storage slots 18 on the connecting bracket 13.

[0019] When the molding mold 6 needs to be disassembled, pull it upwards. When the connecting bracket 13 moves the rotating rod 19 to the auxiliary slot 21, the positioning post 14 has completely released its limiting effect on the molding mold 6. At this time, the handle 20 can be pulled to allow the rotating rod 19 to rotate and unfold along the storage groove 18, so that the rotating rod 19 can rotate into the auxiliary slots 21 on both sides of the positioning sleeve 11. At this time, the rotating rod 19 forms a downward limiting effect on the connecting bracket 13, thereby effectively preventing the positioning post 14 from moving during the movement, avoiding the problem of the positioning post 14 contacting the installation guide groove 7, and further improving the convenience of loading and unloading the molding mold 6.

[0020] This invention provides a die stamping device, the specific working principle of which is as follows: When it is necessary to replace the molding die 6, first pull the handle 15 upwards, so that the connecting bracket 13 is driven by the force of the handle 15 to move the positioning pin 14 upwards along the guide pin 12. The return spring 17 outside the guide pin 12 is compressed and deformed by the connecting bracket 13 to store force. When the positioning pin 14 is completely removed from the inside of the positioning hole 16, the positioning pin 14 releases its lateral limiting effect on the molding die 6. Then, the molding die 6 can be pushed laterally, so that the molding die 6 drives the two sets of guide bars 8 to slide outwards along the mounting guide groove 7. The card holder 10 can be pulled out from the insertion port 9 on the molding die 6 and inserted into the new die to be replaced. Then, repeat the above operation in reverse, so that the molding die 6 drives the card holder 10 to move to the center of the mounting base 5. At this time, the positioning pin 14 can move downwards under the elastic force of the return spring 17, so that the positioning pin 14 can be quickly inserted into the positioning hole 16 at the bottom of the mounting guide groove 7, quickly completing the limiting effect on the molding die 6 and completing the entire molding die 6 replacement process. Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
