[0001] This utility model relates to the field of stainless steel pipe forming technology, and in particular to a high-precision mold for stainless steel pipe forming. Background Technology

[0002] Stainless steel pipes are widely used in numerous fields due to their advantages such as corrosion resistance, high strength, good toughness, and aesthetic appearance. In the construction industry, they are used for building decoration and water supply and drainage systems; in the machinery manufacturing industry, they are an important material for manufacturing mechanical structural components and hydraulic fittings; in the automotive industry, they are used for vehicle exhaust systems and fuel delivery pipelines; and in the aerospace industry, they are used to manufacture aircraft hydraulic system pipelines and engine components. With the continuous development of various industries, the requirements for the quality, precision, and performance of stainless steel pipes are also increasing.

[0003] Currently, a high-precision mold for forming stainless steel pipes is constructed using multiple bolts for assembly and disassembly. When internal modules need to be replaced, the bolt assembly and disassembly of each component is time-consuming, labor-intensive, and extremely cumbersome, resulting in significant limitations and poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, the entire mold is installed and disassembled by multiple bolts. When it is necessary to replace its internal modules, the installation and disassembly of the bolts of each component is time-consuming and laborious, which is very troublesome, has great limitations, and poor practicality. Therefore, a high-precision mold for stainless steel pipe forming is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision mold for forming stainless steel pipes, comprising a mounting base, two symmetrical mold bodies at the front end of the mounting base, connecting plates on both sides of the mounting base, clamping plates fixed at one end of each of the two connecting plates, two locking blocks fixed at opposite ends of each of the two clamping plates, locking grooves matching the locking blocks at both ends of the mold bodies, a driving structure for driving the two connecting plates to move in opposite directions within the mounting base, two modules mounted on the mounting base by bolts, a first fixing frame fixed at the rear end of the mounting base, a controller mounted at the rear end of the first fixing frame, an injection hole at the top of the upper mold body, and a first mounting hole on the outer side of the injection hole.

[0006] Preferably, the drive structure includes a motor mounted on the inner wall of the mounting base, the output end of the motor is fixed with a bidirectional screw, both ends of the outer wall of the bidirectional screw are threaded with movable plates, both ends of the two movable plates are slidably connected with limit posts, one opposite end of the two movable plates is fixed with a connecting block, and the opposite ends of the two sets of connecting blocks pass through the mounting base and are respectively fixed to the two connecting plates.

[0007] Preferably, a first electric telescopic rod is installed at the front end of the first fixed frame, a fixed plate is fixed at the output end of the first electric telescopic rod, a push block is fixed at the front end of the fixed plate, and the end of the push block away from the fixed plate passes through the mounting base and is located inside the mold body.

[0008] Preferably, a barrier plate is placed together at the front ends of the two mold bodies, a second fixing frame is fixed at the top of the upper mold body, a second electric telescopic rod is installed at the bottom of the second fixing frame, and the output end of the second electric telescopic rod is fixed to the barrier plate.

[0009] Preferably, mounting plates are fixed at both ends of the first fixing frame, and multiple second mounting holes are provided in the mounting plates. Sealing blocks are fixed on both sides of the bottom end of the upper mold body, and sealing grooves matching the sealing blocks are provided on both sides of the top end of the lower mold body.

[0010] Preferably, the end of the bidirectional screw away from the motor is rotatably connected to the mounting base, and both ends of the limiting post are fixed to the mounting base.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the operation of the motor drives the bidirectional screw to rotate, causing the two moving plates to move towards or away from each other under the limitation of the limiting post. This, in turn, causes the two connecting plates connected by the two sets of connecting blocks to move towards or away from each other. When the two connecting plates move towards each other, the locking blocks fixed at one end of the two clamping plates will engage with the mold body, achieving the effect of quick installation of the mold body. When the two connecting plates move in opposite directions, the two locking blocks will disengage from the locking slots opened at both ends of the mold body, thereby enabling quick disassembly of the mold body. This facilitates the rapid installation and disassembly of the modules, making it more practical. Furthermore, the operation of the first electric telescopic rod can drive the fixed plate to move, thereby driving the push block to move, facilitating the automatic ejection of the stainless steel tube formed inside the mold body.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a high-precision mold for forming stainless steel pipes, including a mounting base 1. The front end of the mounting base 1 is provided with two symmetrical mold bodies 6. Both sides of the mounting base 1 are provided with connecting plates 2. One end of each of the two connecting plates 2 is fixed with a clamping plate 3. Two clamping blocks 4 are fixed at opposite ends of each of the two clamping plates 3. Both ends of the mold body 6 are provided with slots 5 that match the clamping blocks 4. The mounting base 1 is provided with a driving structure 9 for driving the two connecting plates 2 to move in opposite directions. Two modules 7 are installed on the mounting base 1 by bolts 8. The rear end of the mounting base 1 is fixed with a first fixing frame 10. The rear end of the first fixing frame 10 is equipped with a controller 23. The top of the upper mold body 6 has an injection hole 19. A first mounting hole 20 is provided on the outer side of the injection hole 19.

[0021] The overall effect of embodiment 1 is that, through the operation of the drive structure 9, the two connecting plates 2 can be driven to move in opposite directions. When the two connecting plates 2 move in opposite directions, the two clamping plates 3 will be driven to engage with the locking blocks 4 fixed at one end of the mold body 6, achieving the effect of quick installation of the mold body 6. When the two connecting plates 2 move in opposite directions, the two locking blocks 4 will be driven to disengage from the locking slots 5 opened at both ends of the mold body 6, thereby enabling quick disassembly of the mold body 6. This facilitates the quick installation and disassembly of the module 7, making it more practical. The module 7 can be replaced by setting the bolts 8. By replacing the module 7 with modules of different widths and cooperating with the inner wall of the mold body 6, stainless steel pipes of different thicknesses can be processed to achieve a high-precision effect. The injection hole 19 is used to heat the injection liquid of the stainless steel pipe. The first mounting hole 20 is set to facilitate the installation of external injection molding devices.

[0022] Example 2, as Figure 1-4 As shown, the drive structure 9 includes a motor 901 mounted on the inner wall of the mounting base 1. A bidirectional screw 902 is fixed to the output end of the motor 901. Moving plates 903 are threaded to both ends of the outer wall of the bidirectional screw 902. Limiting posts 904 are slidably connected to both ends of the two moving plates 903. Connecting blocks 905 are fixed to the opposite ends of the two moving plates 903. The opposite ends of the two sets of connecting blocks 905 penetrate the mounting base 1 and are respectively fixed to the two connecting plates 2. A first electric telescopic rod 11 is mounted at the front end of the first fixed frame 10. A fixed plate 12 is fixed to the output end of the first electric telescopic rod 11. A push block 13 is fixed to the front end of the fixed plate 12. The end of the push block 13 away from the fixed plate 12 penetrates the mounting base 1 and is set... Inside the mold body 6, the front ends of the two mold bodies 6 are fitted together with a baffle plate 18. The top of the upper mold body 6 is fixed with a second fixing frame 16. The bottom of the second fixing frame 16 is equipped with a second electric telescopic rod 17. The output end of the second electric telescopic rod 17 is fixed to the baffle plate 18. Both ends of the first fixing frame 10 are fixed with mounting plates 21. Multiple second mounting holes 22 are opened in the mounting plates 21. Both sides of the bottom end of the upper mold body 6 are fixed with sealing blocks 14. Both sides of the top end of the lower mold body 6 are provided with sealing grooves 15 that match the sealing blocks 14. The end of the bidirectional screw 902 away from the motor 901 is rotatably connected to the mounting base 1. Both ends of the limiting post 904 are fixed to the mounting base 1.

[0023] The overall effect of embodiment 2 is that the operation of motor 901 drives the bidirectional screw 902 to rotate, causing the two moving plates 903 to move towards or away from each other under the limit of the limiting post 904, thereby driving the two connecting plates 2 connected by the two sets of connecting blocks 905 to move towards or away from each other. The operation of the first electric telescopic rod 11 can drive the fixed plate 12 to move, thereby driving the push block 13 to move to facilitate the automatic ejection of the stainless steel tube formed in the mold body 6. The operation of the second electric telescopic rod 17 can drive the barrier plate 18 to rise and fall. When the barrier plate 18 falls, it can block the front end of the mold body 6 to facilitate injection molding and heating. When the barrier plate 18 rises, it will open the front end opening of the mold body 6 to facilitate the ejection of the formed stainless steel tube. The controller 23 of this device can control the operation of motor 901, first electric telescopic rod 11 and second electric telescopic rod 17.

[0024] Working principle: When in use, the motor 901 drives the bidirectional screw 902 to rotate, causing the two moving plates 903 to move towards or away from each other under the limitation of the limiting post 904. This, in turn, causes the two connecting plates 2 connected by the two sets of connecting blocks 905 to move towards or away from each other. When the two connecting plates 2 move towards each other, the locking blocks 4 fixed at one end of the two clamping plates 3 will engage with the mold body 6, achieving the effect of quick installation of the mold body 6. When the two connecting plates 2 move in opposite directions, the two locking blocks 4 will disengage from the slots 5 opened at both ends of the mold body 6, thereby enabling quick disassembly of the mold body 6 and facilitating the rapid installation of the module 7. The device is easy to install and dismantle, making it more practical. The operation of the first electric telescopic rod 11 can drive the fixed plate 12 to move, thereby driving the push block 13 to move and automatically push out the stainless steel tube formed in the mold body 6. The operation of the second electric telescopic rod 17 can drive the baffle plate 18 to rise and fall. When the baffle plate 18 falls, it can block the front end of the mold body 6 to facilitate injection molding and heating. When the baffle plate 18 rises, it will open the front opening of the mold body 6 to facilitate the ejection of the formed stainless steel tube. The installation plate 21 and the second installation hole 22 make it easy to install the whole device.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the controller 23, motor 901, first electric telescopic rod 11 and second electric telescopic rod 17 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
