The top of the lower mold base 2 is located on one side of the lower mold base 21 and is provided with a driving structure for driving the telescopic core to move back and forth in the horizontal direction.

[0021] The top of the lower mold base 2 is fixedly connected to a lower pad 22, and the lower mold plate 21 is fixedly connected to the top of the lower pad 22. The driving structure includes a moving seat 221, and the moving seat 221 is slidably connected to the top of the lower pad 22. The moving seat 221 extends in the vertical direction and passes through the lower mold plate 21. The product telescopic core 4 is fixedly connected to the top of the moving seat 221, and a through groove is opened on the lower mold plate 21 for the moving seat 221 to pass through; the setting of the moving seat 221 limits the moving trajectory of the product telescopic core 4, so that the movement of the product telescopic core 4 is more stable.

[0022] The driving structure also includes a driving member 31 fixedly connected to the fixed seat 3 at the top of the lower mold base 2, a driving member 31 movably connected to the fixed seat 3 in the vertical direction, a driving block 312 and a telescopic movable block 311. A cavity 32 for accommodating the driving member 31 is provided on the fixed seat 3, the driving member 31 is inserted into the cavity 32 and is slidably connected to the inner wall of the cavity 32, one end of the telescopic movable block 311 is rotatably connected to the driving member 31 and is arranged close to the top of the driving member 31, and the other end of the telescopic movable block 311 extends toward the side of the driving member 31 away from the lower template 21, and a groove 321 is provided on the inner wall of the cavity 32 for the telescopic movable block 311 to extend into, and one end of the telescopic movable block 311 is rotatably connected to the inner wall of the groove 321. By setting the groove 321, the groove 321 can be used to maintain The cam 312 is in the state of being rotated to move the cam 314 around the workbench 310, so that the cam 314 can move freely, and the cam 314 can move freely, so that the cam 314 can move freely, and the cam 314 can move freely.

[0023] The bottom of the upper die base 1 is fixedly connected to an upper pad 11, the bottom of the upper pad 11 is fixedly connected to a punch clamp 12, the bottom of the punch clamp 12 is fixedly connected to a back stripping plate 13 through a die spring, the bottom of the back stripping plate 13 is fixedly connected to a stripping plate 14, the bottom of the back stripping plate 13 is fixedly connected to a guide pin 131, the guide pin 131 passes through the stripping plate 14, a positioning hole corresponding to the guide pin 131 is opened on the product, and a concave hole for the guide pin 131 to pass through is opened on the lower template 21. By setting the guide pin 131, when the upper die base 1 is pressed down, the product can be accurately positioned, so that the product can be accurately maintained in the corresponding position, and the extension of the telescopic core can be made more stable.

[0024] A downward pressure transmission pin 151 is provided at the bottom of the upper mold base 1, and the bottom end of the downward pressure transmission pin 151 is in conflict with the top of the driving member 31. A first slide groove 15 is provided on the upper mold base 1 for the downward pressure transmission pin 151 to slide, and a first elastic member 152 is provided in the first slide groove 15. The first elastic member 152 has elastic deformation potential energy for pushing the downward pressure transmission pin 151 to extend out of the first slide groove 15. By setting the first slide groove 15, the movement trajectory of the downward pressure transmission pin 151 is limited; two reset force transmission pins 231 are inserted into the top of the lower mold base 2, and the top of the reset force transmission pin 231 is in conflict with the bottom of the driving member 31. A second slide groove 23 is provided on the lower mold base 2 for the reset force transmission pin 231 to slide, and a second elastic member 152 is provided in the second slide groove 23 The second elastic member 232 has the elastic deformation potential energy of pushing the downward pressure transmission pin 151 to extend out of the second slide groove 23. The elastic force of the first elastic member 152 is greater than the elastic force of the second elastic member 232. When the upper mold base 1 is away from the lower mold base 2, that is, the downward pressure transmission pin 151 is away from the driving member 31, the second elastic member 232 is reset by its own elastic force, thereby resetting the driving member 31. The driving member 31 moves upward, so that the driving block 312 pulls the moving seat 221 to reset, and the product telescopic core 4 extends out of the product, so that the product can move smoothly and complete the reciprocating motion of the product telescopic core 4; and the reset force transmission pins 231 are set to two, so that the reset of the driving member 31 is more stable.

[0026] Working principle: The upper die base 1 moves away from the lower die base 2, and the first elastic member 152 pushes the downward force transmission pin 151 through its own elasticity, causing the downward force transmission pin 151 to extend out of the first slide 15. The second elastic member 232 pushes the reset force transmission pin 231 through its own elasticity, causing the two reset force transmission pins 231 to extend out of the second slide 23 and push the driving member 31 to reset, causing the driving block 312 and the telescopic movable block 311 to rotate in a direction toward each other, so that the driving block 312 pulls the movable seat 221 away from the work station;

[0027] The product is placed on the workstation, between the two guide plates, and the upper die base 1 is pressed down close to the lower die base 2 until the stripper plate 14 contacts the guide plate. At this time, the guide pin 131 extends into the positioning hole of the product, so that the product is stably fixed in the corresponding position. At this time, the force transmission pin 151 is pressed down to push the driving member 31, so that the driving member 31 moves downward, and the driving block 312 and the telescopic movable block 311 rotate in the direction away from each other, so that the driving block 312 pushes the movable seat 221 close to the workstation, and the product telescopic core 4 extends into the product to support the middle of the product, so that it can be well shaped;

[0028] When the product is formed, the upper mold base 1 moves away from the lower mold base 2, and the second elastic member 232 pushes the reset force transmission pin 231 through its own elasticity, so that the two reset force transmission pins 231 extend out of the second slide groove 23 and push the driving member 31 to reset, and the driving block 312 and the telescopic movable block 311 rotate in the direction of approaching each other, so that the driving block 312 pulls the movable seat 221 away from the work station, and the product telescopic core 4 moves away from the product, so that the product can continue to move.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
