A buffer assembly 4 is provided outside the connecting plate 3, and a baffle plate 201 is provided, and three baffle plates 201 are provided. When the three baffle plates 201 are engaged and connected with the baffle plate 104, a closed cavity is formed, so that it is convenient to form the draw rod box body. By providing a push rod 206, when the push rod 206 is reset, it drives the connecting plate 3 to move, so that the three baffle plates 201 are separated from the draw rod box body, so that it is convenient to demould the draw rod box body. By providing a push rod 1 202, when the guide ring 205 moves, it drives the push rod 1 202 to move, so that the push rod 1 202 drives the baffle plate 201. By providing a guide rod 204, it is convenient for the guide ring 205 to move along the direction of the guide rod 204.

[0022] The mold assembly 1 includes an upper mold 101, and a hydraulic rod 102 is fixedly connected to the upper mold 101, a mold base 103 is arranged under the upper mold 101, and a baffle 1 104 is fixedly connected to the mold base 103, the mold base 103 is slidably connected to the baffle 2 201, and three baffles 201 are arranged in sequence along the center of the mold base 103, and the baffle 2 201 is snap-connected with the baffle 1 104.

[0023] The buffer assembly 4 includes a limiting column 401, and the limiting column 401 is fixedly connected to the mold base 103 at the bottom. Three limiting columns 401 are arranged in sequence along the center of the mold base 103, and one end of the limiting column 401 is arc-shaped. By setting the limiting column 401, when the limiting column 401 is engaged with the connecting plate 3, and one end of the limiting column 401 is arc-shaped, the limiting rod 406 is pushed to move along the direction of the elastic rope 407, so that the limiting rod 406 is separated from the push rod 206.

[0024] A telescopic rod 402 is fixedly connected to the connecting plate 3 , and the telescopic rod 402 is fixedly connected to the upper mold 101 .

[0025] The telescopic rod 402 is outerly connected with a buffer spring 403, and one end of the buffer spring 403 is fixedly connected to the connecting plate 3, and the other end of the buffer spring 403 is fixedly connected to the bottom of the upper mold 101. By providing the telescopic rod 402 and the buffer spring 403, the connection between the upper mold 101 and the connecting plate 3 is ensured by the telescopic rod 402. When the buffer spring 403 and the telescopic rod 402 are compressed, the operation of the upper mold 101 is guaranteed.

[0026] A limiting groove 404 is provided in the push rod 206, and the limiting groove 404 is arranged corresponding to the limiting column 401. A slot 405 is provided on one side of the connecting plate 3, and a limiting rod 406 is slidably connected in the slot 405. Two limiting rods 406 are symmetrically arranged along the center of the connecting plate 3, and the limiting rod 406 is snap-connected with the push rod 206. By setting the slot 405, the limiting rod 406 is easily slidably connected along the slot 405.

[0027] One end of the limit rod 406 is arc-shaped, and one side of the limit rod 406 is fixedly connected to an elastic rope 407, and one side of the elastic rope 407 is fixedly connected to the slot 405. By setting the limit rod 406 and the elastic rope 407, when the elastic rope 407 maintains its original length, the limit rod 406 is pulled to engage with the push rod 206, thereby limiting the push rod 206. When the elastic rope 407 is stretched, the limit rod 406 is disengaged from the push rod 206, thereby releasing the limit on the push rod 206, and one end of the limit rod 406 is arc-shaped, so that it is convenient for the limit column 401 to push the limit rod 406 to disengage from the push rod 206.

[0028] Working principle: When the mold is used, the hydraulic rod 102 is started so that the hydraulic rod 102 pushes the upper mold 101 to move along the guide rod 204, and at the same time drives the push rod 206 to move, so that the push rod 206 pushes the connecting plate 3 to move along the guide rod 204, and pushes the guide ring 205 to move along the guide rod 204 through the connecting plate 3, so that the push rod 1 202 pushes the baffle 201 to move along the surface of the mold base 103, so that the three baffles 201 and the baffle 1 104 are engaged with each other to form a closed cavity. When the hydraulic rod 102 is continuously running, the limit column 401 is engaged with the limit groove 404 provided in the push rod 206, and one end of the limit column 401 is arc-shaped, thereby pushing the limit rod 406 to move along the direction of the slot 405, and at the same time stretching the elastic rope 407. Thereby, the limit on the push rod 206 is released, and the use of the mold is guaranteed. When the upper mold 101 moves, the telescopic rod 402 and the buffer spring 403 are compressed, thereby achieving a buffering effect, preventing damage to the mold and ensuring the service life of the mold. After the tie rod box is formed, the hydraulic rod 102 is started to drive the upper mold 101 to reset, so that the elastic recovery of the elastic rope 407 drives the limit rod 406 to reset, thereby limiting the push rod 206, and the upper mold 101 continues to move, driving the guide ring 205 to move along the guide rod 204, so that the push rod 1 202 drives the baffle 201 to disengage from the tie rod box, thereby completing the demoulding of the tie rod box, thereby facilitating the demoulding of the tie rod box and preventing the tie rod box from being damaged due to demoulding, thereby completing the use of the mold.
