The inner side of the vertical plate 7 is movably connected with a bidirectional screw 8 located inside the fixed mold 1 through a bearing. Both ends of the bidirectional screw 8 penetrate to the outside of the vertical plate 7 and are fixedly connected with a rotating wheel 9. The left and right sides of the surface of the bidirectional screw 8 are threadedly connected with a screw sleeve 10 located inside the fixed mold 1. The front and rear sides of the top of the screw sleeve 10 are fixedly connected with a pressure rod 11. The top of the pressure rod 11 penetrates the opening 5 and extends to the top of the fixed mold 1. The outer side of the claw 4 is fixedly connected with a force plate 12, and the outer surface of the pressure rod 11 contacts the outer side of the force plate 12.

[0032] As a technical optimization solution of the utility model, by setting a bidirectional screw 8, a screw sleeve 10, a pressure rod 11 and a force plate 12, multiple claws 4 can be driven to swing at the same time, which can facilitate the user to adjust the extrusion strength of the claws 4 to meet the fixing requirements of mold cores 2 of different sizes.

[0033] refer to Figure 4 The inner side of the vertical plate 7 is fixedly connected with a guide rod 13 located on both sides of the bidirectional screw 8, and the screw sleeve 10 is sleeved on the surface of the guide rod 13, and the guide rod 13 and the screw sleeve 10 are slidably connected.

[0034] As a technical optimization solution of the present invention, by providing a guide rod 13, the screw sleeve 10 can be limited to avoid the screw sleeve 10 from tilting during the movement.

[0041] The working principle and use process of the utility model are as follows: when in use, first place the material on the top of the mold core 2, and the molding machine applies downward pressure and squeezes the material on the surface of the mold core 2 to make it stretch and deform. When the mold core 2 needs to be replaced, first turn the rotating wheel 9, and the rotating wheel 9 drives the bidirectional screw 8 to rotate. The bidirectional screw 8 uses the thread to push the screw sleeve 10 to move towards each other. During the movement of the screw sleeve 10, the pressure rod 11 is driven to slide inside the opening 5. When the pressure rod 11 is out of contact with the force plate 12, the claw 4 connected to the force plate 12 loses pressure and swings with the pin shaft as the axis. When the claw 4 is out of connection with the mold core 2, the user can directly replace the mold core 2.

[0042] To sum up: the stretching resonant rod stretching mold, through the transmission structure 6, is separated from the contact state with the claw 4, so that the claw 4 loses pressure and swings with the pin shaft as the axis. When the claw 4 is disconnected from the mold core 2, the user can directly replace the mold core 2, replacing the existing operation steps of disassembling and assembling the threaded components through tools, saving time and effort, and improving the replacement and maintenance efficiency. At the same time, it can increase the contact area between the mold core 2 and the fixed mold 1, and improve the force impact effect.
