[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Referring to the accompanying drawings: the forging die of this track iron tooth includes a base 1, support seats 3 are fixed on both sides of the base 1 through support columns 2, a hydraulic cylinder 31 is fixed on the surface of the support seat 3, and a pressure plate 4 is fixed to the end surface of the hydraulic rod at the lower end of the hydraulic cylinder 31. The pressure plate 4 and the base 1 are both provided with mounting cavities 7 for mounting an upper die cover 5 and a lower die seat 6. The mounting cavity 7 is provided with a limiting unit 8 on the pressure plate 4 or the base 1. The limiting unit 8 has two states, unlocked and locked, and is switched by movement to prevent the upper die cover 5 or the lower die seat 6 from detaching from the mounting cavity 7 in the locked state, and to make the upper die cover 5 or the lower die seat 6 detach from the mounting cavity 7 in the unlocked state. A holding unit 9 is provided on the outer surface of the pressure plate 4 or the base 1 to cooperate with the limiting unit 8 and maintain the state. The principle of the utility model is to use the installation cavity 7 to provide a clear installation position for the upper mold cover 5 and the lower mold base 6 on the pressure plate 4 and the base 1, and then use the limiting unit 8 to limit the position of the upper mold cover 5 and the lower mold base 6, that is, they are present in the installation cavity 7 and on the exit path of the upper mold cover 5 and the lower mold base 6. The holding unit 9 enables the limiting unit 8 to maintain the state after the use state is adjusted, especially when replacing, so that there is no need for continuous manual control. This method is more convenient than the traditional bolt installation operation, and the efficiency of replacing the upper mold cover 5 or the lower mold base 6 is higher.

[0021] The mounting cavity 7 has a first opening 71 and a second opening 72 on the pressing plate 4 or the base 1. The upper mold cover 5 or the lower mold base 6 enters through the first opening 71 and moves to the final position and is then exposed to the outside of the pressing plate 4 or the base 1 through the second opening 72. That is, the mounting cavity 7 is in a convex shape. The first opening 71 serves as an inlet and outlet, so that the upper mold cover 5 or the lower mold base 6 can enter and exit the mounting cavity 7. The second opening 72 serves as an exposure port, so that the mold part of the upper mold cover 5 or the lower mold base 6 placed in the mounting cavity 7 can be exposed to the outside, thereby facilitating the assembly of the upper mold cover 5 and the lower mold base 6 during processing.

[0022] The mounting cavity 7 is provided with an unlocking cavity 73 on the pressure plate 4 or the base 1. The limiting unit 8 is converted from a locked state to an unlocked state by moving from the mounting cavity 7 to the unlocking cavity 73. The unlocking cavity 73 provides space for the limiting unit 8, that is, the limiting unit 8 is moved from the mounting cavity 7 to the unlocking cavity 73, thereby no longer existing on the exit path of the upper mold cover 5 or the lower mold base 6, thereby facilitating the replacement of the upper mold cover 5 or the lower mold base 6.

[0023] The limiting unit 8 includes a limiting block 81, a connecting rod 82, a supporting block 83, and an anti-slip cap 84. The limiting block 81 is placed in the installation cavity 7 when in the locked state and in the unlocking cavity 73 when in the unlocked state. The connecting rod 82 moves to the pressure plate 4 or the base 1 and is connected to the limiting block 81. The supporting block 83 is rotatably connected to the connecting rod 82 and supported on the outer surface of the pressure plate 4 or the base 1, and allows the use state to be switched by rotation and used in conjunction with the holding unit 9. The anti-slip cap 84 is connected to the upper end of the connecting rod 82 to prevent the supporting block 83 from falling out of the connecting rod 82. Such a setting enables the limiting unit 8 to have the restraining ability to prevent the upper mold cover 5 or the lower mold base 6 from falling out, and also has the ability to facilitate the user to operate the limiting unit, and also has the ability to cooperate with the holding unit 9 to maintain the state of the limiting unit 8, thereby quickly realizing the use state conversion of the limiting unit 8, and can be maintained after the conversion, and the anti-slip cap 84 prevents the support block 83 from falling out.

[0024] The holding unit 9 includes a positioning block 91 and an extension block 92 extending from the positioning block 91. The positioning block 91 is arranged on the outer surface of the pressure plate 4 or the base 1. The extension block 92 is located at the upper section of the positioning block 91 and forms a spacing with the outer surface of the pressure plate 4 or the base 1 for the support block 83 to be placed therein so that the locking state of the limiting unit 8 is maintained. The positioning block 91 and the extension block 92 share a supporting positioning surface 93. The support block 83 is arranged on the supporting positioning surface 93 so that the unlocked state is maintained. The positioning block 91 is used to determine the use position of the holding unit 9. The purpose of the extension block 92 is to form a space and to increase the upper end area of ​​the positioning block 91, that is, the supporting positioning surface 93. The space is used for the support block 83 to be placed therein, so that the limiting unit 8 can be maintained in a locked state, and at the same time, the support block 83 is placed on the supporting positioning surface 93 to maintain the unlocked state when unlocking.

[0025] The support block 83 rotates eccentrically on the connecting rod 82, so as not to interfere with the movement of the limiting unit 8. That is, the eccentric rotation makes the narrow width part of the support block 83 close to the retaining unit 9 when the limiting unit 8 moves, and the outer peripheral surface of the support block 83 is also in contact with the outer peripheral surface of the extension block 92, thereby increasing the movement stability.

[0026] The positioning block 91 is fixed to the pressing plate 4 or the base 1 by bolts, which makes it easy to disassemble and assemble the positioning block 91 .

[0027] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
