[0031] A limit device is provided on the support base 1;

[0032] The limiting device includes a lower mold 2 and a limiting seat 10. A lower mold groove 16 is formed on the upper surface of the support base 1. The outer wall of the lower mold 2 is slidably connected to the interior of the lower mold groove 16. Grooves 13 are formed on both inner walls of the lower mold groove 16. The outer walls of the protrusions on both sides of the lower mold 2 are slidably connected to the interiors of the corresponding grooves 13. The outer walls of the protrusions on both sides of the limiting seat 10 are slidably connected to the interiors of the corresponding grooves 13. One outer wall of the lower mold 2 contacts one side of the arc-shaped surface of the limiting seat 10. Two second limiting fixing block grooves 15 are formed inside the lower mold groove 16. Two first limiting fixing block grooves 11 are formed on the upper surface of the limiting seat 10. Limiting fixing blocks 12 are slidably connected inside each of the two first limiting fixing block grooves 11. The two limiting fixing blocks 12 are close to the second limiting fixing block grooves 15. One end of each of the two limit blocks 12 slides into the interior of the lower mold groove 16 and is slidably connected to the interior of the corresponding second limit block groove 15. The upper surface of the limit block 10 has two first limit block grooves 14. Limit blocks 9 are slidably connected inside the two first limit block grooves 14. Both limit blocks 9 are "L" shaped. A return spring 8 is provided inside the two first limit block grooves 14. The outer wall of the upper protrusion of each of the two limit blocks 12 has a second limit block groove 17. The lower end of each of the two limit blocks 9 near the second limit block groove 17 slides into the interior of the first limit block groove 14 and contacts the inner wall of the corresponding second limit block groove 17. The two ends of the two return springs 8 are fixedly connected to the upper outer wall of the corresponding limit block 9 and the inner wall of the first limit block groove 14, respectively.

[0033] The support base 1 has four support columns at the top, with a top plate 4 fixedly connected to the ends away from the support base 1. A cylinder 5 is fixedly connected to the upper surface of the top plate 4. A mounting base 6 is provided on the support base 1. The output end of the cylinder 5 slides to the lower end of the top plate 4 and is fixedly connected to the upper surface of the mounting base 6. Fixing blocks 7 are slidably connected to the two grooves on the lower surface of the mounting base 6. An upper mold 3 is provided on the support base 1. The outer walls of the two protrusions on the upper surface of the upper mold 3 are slidably connected to the two grooves on the lower surface of the mounting base 6. One side of the outer wall of the two fixing blocks 7 is in contact with the outer walls of the two protrusions on the upper surface of the upper mold 3. Two fixing bolts 18 are threadedly connected to the upper surface of the mounting base 6. The ends of the two fixing bolts 18 near the fixing blocks 7 are threaded to the grooves on the lower surface of the mounting base 6 and are threadedly connected to the grooves on the upper surface of the corresponding fixing blocks 7. The ends of the two fixing rods slidably connected to the upper surface of the top plate 4 near the mounting base 6 are slidably extended to the lower end of the top plate 4 and are fixedly connected to the upper surface of the mounting base 6.

[0034] Furthermore, when using this device, it is started by connecting to an external power source. First, the heated material is placed in the lower mold 2. Then, the output end of the cylinder 5 moves downward, causing the mounting base 6 to move downward, which in turn moves the upper mold 3 downward. The upper mold 3 and the lower mold 2 cooperate to form a closed cavity, in which the material is forged. Then, when it is necessary to disassemble the lower mold 2, the upper end of the limiting block 9 is pushed to move in the opposite direction, causing the return spring 8 to contract, while its other end outer wall disengages from the inside of the second limiting block groove 17. After removing the contact, pull the handle on the limit fixing block 12 upwards to remove the limit fixing block 12. Then, pull the handle on the limit card seat 10 to remove the limit card seat 10 from the support base 1. Then, pull the lower mold 2 to remove it from the support base 1. Next, when it is necessary to disassemble the upper mold 3, turn the fixing bolt 18 to rotate it so that the outer wall of its other end is no longer in contact with the groove on the upper surface of the fixing block 7. Then, after removing the fixing block 7 from the mounting base 6, pull the upper mold 3 to remove it from the mounting base 6.

[0035] By pushing the upper end of the limiting block 9 in the limiting device to move in the opposite direction, the return spring 8 is contracted, causing its other outer wall to disengage from the inside of the second limiting block groove 17. Then, the upper handle of the limiting fixing block 12 is pulled upwards, thus removing the limiting fixing block 12. After the limiting fixing block 12 is pulled out, the upper handle of the limiting card seat 10 can be pulled to remove the limiting card seat 10 from the support base 1. Then, the lower mold 2 can be removed from the support base 1. This disassembly of the lower mold 2 is simple and quick, thus effectively improving the disassembly efficiency of the lower mold 2, while also improving the practicality of the equipment and reducing the time and labor required for the disassembly process. By turning the fixing bolt 18, its other outer wall is disengaged from the groove on the upper surface of the fixing block 7. Then, the fixing block 7 is removed from the mounting base 6, and the upper mold 3 can be removed from the mounting base 6. This facilitates the disassembly of the upper mold 3, effectively improving the maintenance and repair efficiency of the upper mold 3, while also increasing the service life of the upper mold 3, thereby improving the work efficiency of the staff.

[0036] Working principle: First, the heated material is placed in the lower mold 2. Then, the output end of the cylinder 5 moves downward, driving the mounting base 6 downward and simultaneously driving the upper mold 3 downward. The upper mold 3 and the lower mold 2 cooperate to form a closed cavity, in which the material is forged. When the lower mold 2 needs to be disassembled, the upper end of the limiting block 9 is pushed to move in the opposite direction, causing the return spring 8 to contract and disengage its other end outer wall from the inside of the second limiting block groove 17. Then, the upper handle of the limiting fixing block 12 is pulled upward to remove the limiting fixing block 12. After the limiting fixing block 12 is pulled out, the upper handle of the limiting card seat 10 can be pulled to remove the limiting card seat 10 from the support base 1. Then, the lower mold 2 can be pulled to remove it from the support base 1. When the upper mold 3 needs to be disassembled, the fixing bolt 18 is turned to rotate it so that its other end outer wall disengages from the groove on the upper surface of the fixing block 7. After the fixing block 7 is removed from the mounting base 6, the upper mold 3 can be pulled to remove it from the mounting base 6.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
