The number of the bidirectional threaded rods 41 is two, which are respectively arranged on the base 1 and the mounting seat. Inside the seat 3, a handle 42 is provided at one end of the bidirectional threaded rod 41, clamping plates 43 are provided at both ends of the surface of the bidirectional threaded rod 41, connecting rods 1 431 are provided on both sides of the clamping plate 43, a fixing plate 432 is provided at the bottom end of the connecting rod 1 431, an anti-slip pad 433 is provided on the bottom side of the fixing plate 432, a screw rod 434 is provided on the top of the clamping plate 43, a movable block 435 is provided at the bottom end of the screw rod 434, connecting rods 2 436 are provided on both sides of the movable block 435, and a knob 437 is provided on the top of the screw rod 434;

[0025] By rotating the knobs 437 on both sides of the mold, in conjunction with the screw 434, the movable block 435, the second connecting rod 436, and the first connecting rod 431, the fixed plate 432 can be driven to move upward, so that the distance between the anti-slip pad 433 and the top side of the mold is increased, and then the handle 42 is rotated to drive the two clamping plates 43 away from each other, so that the distance between the clamping plates 43 and the two sides of the mold is increased, and the mold can be disassembled.

[0026] See also Figure 3 to Figure 4 The two-way threaded rod 41 is rotatably connected to the inside of the base 1 and the mounting seat 3 respectively, the handle 42 is fixedly connected to one end of the two-way threaded rod 41, the clamping plate 43 is threadedly connected to the surface of the two-way threaded rod 41, the connecting rod 431 is rotatably connected to both sides of the clamping plate 43, the fixing plate 432 is fixedly connected to the bottom end of the connecting rod 431, the anti-skid pad 433 is fixedly connected to the bottom side of the fixing plate 432, the screw 434 is threadedly connected to the top of the clamping plate 43, the movable block 435 is sleeved on the bottom end of the screw 434, one end of the connecting rod 436 is rotatably connected to the movable block 435, and the other end is rotatably connected to the connecting rod 431, the knob 437 is fixedly connected to the top of the screw 434, and the material of the anti-skid pad 433 is anti-skid silicone.

[0027] During installation, two clamping plates 43 are used to clamp and fix the two sides of the mold, and at the same time, the fixing plate 432 and the anti-skid pad 433 are used to fix the top side of the mold to make it more firmly fixed. The anti-skid pad 433 is anti-skid silicone, which can increase the friction with the mold and prevent the mold from shifting.

[0028] See also Figure 1 to Figure 2 A lower mold 5 is installed on the top of the base 1 through a disassembly component 4, and an upper mold 6 is installed on the bottom of the mounting seat 3 through a disassembly component 4. A top plate 7 is fixedly connected to the top of the guide rod 2, and a hydraulic rod 8 is fixedly installed on the top side of the top plate 7. The output shaft of the hydraulic rod 8 is fixedly connected to the mounting seat 3. A buffer component 9 is arranged between the base 1 and the mounting seat 3. The buffer component 9 includes a buffer spring 91, a slot hole 1 92 and a slot hole 2 93. The surface of the guide rod 2 is sleeved with a buffer spring 91. The four corners of the bottom side of the mounting seat 3 are provided with slot holes 1 92, and the four corners of the top side of the base 1 are provided with slot holes 2 93.

[0029] By providing a buffer component 9, a buffer effect can be achieved during the mold stamping process to reduce the noise generated. During the mold closing process, the mounting seat 3 moves downward to squeeze the buffer spring 91, causing the buffer spring 91 to undergo compression deformation. The compression deformation of the buffer spring 91 absorbs the force caused by the vibration, thereby achieving a buffer effect.

[0030] In the utility model, the working steps of the device are as follows:

[0031] The first step: when the mold needs to be disassembled and replaced, first turn the knobs 437 on both sides of the mold, which can drive the screw rod 434 to rotate and move downward at the same time, thereby driving the movable block 435 to move downward, so that it pulls one end of the second connecting rod 436 on both sides, and one end of the second connecting rod 436 pushes the first connecting rod 431, driving the first connecting rod 431 to rotate on the clamping plate 43, which can drive the fixed plate 432 to move upward, so that the distance between the anti-skid pad 433 and the top side of the mold increases, and then turn the handle 42 to drive the two-way threaded rod 41 to rotate, which can drive the two clamping plates 43 to move away from each other, so that the distance between the clamping plates 43 and the two sides of the mold increases, and the mold can be disassembled, and the mold can be reinstalled by the reverse operation. The entire installation and disassembly process does not require the use of professional tools, and the operation is simple and easy to understand. During installation, the two sides of the mold are clamped and fixed by the two clamping plates 43, and the top side of the mold is fixed with the fixed plate 432 and the anti-skid pad 433, so that it is fixed more firmly.

[0032] The second step: when the mold is stamping, starting the hydraulic rod 8 can push the mounting seat 3 to move toward the lower mold 5 to close the mold. During the closing process, the mounting seat 3 moves downward to squeeze the buffer spring 91, causing the buffer spring 91 to undergo compression deformation. The compression deformation of the buffer spring 91 absorbs the force caused by the vibration, thereby achieving a buffering effect and reducing the noise generated. The buffer spring 91 and the second slot 93 can provide sufficient compression space for the buffer spring 91.
