[0037] The positioning and adjusting mechanism includes an auxiliary fixing component, an adjusting component, a driven component, a releasing component and a rotation limiting component. The positioning component is arranged at the front and rear sides of the top of the die 2, and the positioning component is used to determine the front and rear direction of the die 2 when assembling between the die 2 and the upper die seat 1. The auxiliary fixing component is arranged between the top of the die 2 near the right side and the upper die seat 1, and the auxiliary fixing component is used to auxiliary fix the connection between the die 2 and the upper die seat 1. The adjusting component is arranged at the top of the auxiliary fixing component, and the adjusting component is used to fine-tune the position of the die 2 after the die 2 and the upper die seat 1 are fixed to match the position of the punch 3. The driven component is arranged between the top of the die 2 and the connecting column 51. The releasing component is arranged on the outside of the adjusting component, and the releasing component is used to release the auxiliary fixing component from fixing the die 2. The rotation limiting component is arranged on the right side of the adjusting component, and the rotation limiting component is used to limit the rotation of the adjusting component.

[0038] During operation, when the upper die base 1 and the die 2 are to be assembled, first align the connecting column 51 with the upper die base 1 and pass through the upper die base 1, then screw the upper fixing ring 52 in from the top of the connecting column 51, and then connect the upper fixing ring 52 with the lower fixing ring 53 through bolts and connecting flanges, thereby completing the assembly between the upper die base 1 and the die 2. When the connection between the upper die base 1 and the die 2 is to be released, first release the auxiliary fixing assembly of the die 2 by releasing the assembly, then remove the bolts on the connecting flange, and then unscrew the upper fixing ring 52 from the outside of the connecting column 51, so that the die 2 can be automatically separated from the upper die base 1 under the action of gravity.

[0039] Further, the auxiliary fixing component includes a positioning groove 60, which is provided at a position near the right side of the top end of the concave mold 2, a positioning block 61 is inserted inside the positioning groove 60, and the positioning block 61 is provided at a position near the right side of the bottom end of the upper mold base 1, and a receiving cavity 62 is provided inside the positioning block 61, and a clamping block 63 is slidably connected inside the receiving cavity 62, and one side of the clamping block 63 is clamped with a first clamping groove 64, and the first clamping groove 64 is provided on the right side of the inner wall of the positioning groove 60, and a first spring 65 is further provided inside the receiving cavity 62, and a side of the first spring 65 close to the clamping block 63 is fixedly connected to the clamping block 63, and a side of the first spring 65 away from the clamping block 63 is fixedly connected to the inner wall of the receiving cavity 62;

[0040] During operation, when the die 2 is pushed upward to allow the connecting column 51 to pass through the upper die seat 1, the positioning block 61 is simultaneously inserted into the interior of the positioning groove 60. When the positioning block 61 is inserted into the interior of the positioning groove 60, the inner wall of the positioning groove 60 squeezes the inclined surface opened on the right side of the card block 63, so that the card block 63 moves toward the interior of the storage cavity 62 under the action of the squeezing force, and squeezes the first spring 65, causing the first spring 65 to produce elastic deformation. When the positioning block 61 is completely inserted into the interior of the positioning groove 60, the squeezing force of the inner wall of the positioning groove 60 on the card block 63 disappears. At this time, the card block 63 returns to its original position under the action of the restoring force of the first spring 65 and engages with the first card groove 64. The engagement of the card block 63 with the first card groove 64 plays an effect of auxiliary fixing the connection between the upper die seat 1 and the die 2.

[0041] Further, the driven component includes a slider 54, which is fixedly connected to the bottom end of the connecting column 51, and the slider 54 is slidably connected to the inside of the slide groove 55, the slide groove 55 is opened at the top of the concave mold 2, the slider 54 is adapted to the slide groove 55, and the slider 54 and the slide groove 55 are both designed in an isosceles trapezoidal shape, and the adjustment component includes a screw sleeve 85, the screw sleeve 85 is fixedly connected to the top of the positioning block 61, the screw sleeve 85 is threadedly connected to the outside of the screw rod 81, the left side of the screw rod 81 is rotatably connected to the inner wall of the active cavity 76, the active cavity 76 is opened at a position near the right side of the upper mold base 1, and a sleeve groove 80 is opened on the right side of the screw rod 81, and the inner plug of the sleeve groove 80 is inserted into the inner wall of the sleeve groove 80. A left side of a rotating shaft 79 is provided, and the right side of the rotating shaft 79 extends to the outside of the upper mold base 1, and a rotating button 86 is fixedly connected to the right side of the rotating shaft 79, and a third spring 82 is also provided inside the sleeve groove 80, and a sliding block 83 is fixedly connected to the inner wall of the sleeve groove 80, and the sliding block 83 is slidably connected to the inside of the sliding groove 84, and the sliding groove 84 is opened on the outside of the rotating shaft 79, and the side of the third spring 82 close to the rotating shaft 79 is fixedly connected to the rotating shaft 79, and the side of the third spring 82 away from the rotating shaft 79 is fixedly connected to the inner wall of the sleeve groove 80, and the rotating button 86 is made of engineering plastic, and the outer side of the rotating button 86 is provided with anti-slip grooves;

[0042] During operation, when the position of the die 2 is to be adjusted, the limit of the rotation of the rotation button 86 by the rotation limit assembly is first released, and then the rotation button 86 is rotated to drive the fixedly connected rotation shaft 79 to rotate synchronously, and the rotation shaft 79 drives the screw 81 to rotate synchronously through the sliding block 83 and the sliding groove 84, so that the screw sleeve 85 threadedly connected to the outer side of the screw 81 moves, and drives the fixedly connected positioning block 61 to move synchronously, so that the positioning block 61 pushes the die 2 to move to adjust the position of the die 2, so that the positions of the die 2 and the punch 3 are adapted, and when the die 2 is adjusted to the specified position, the limit of the rotation of the rotation button 86 by the rotation assembly is restored to prevent the rotation button 86 from accidentally rotating and causing the position of the die 2 to shift;

[0043] When the die 2 moves under the push of the positioning block 61, the slider 54 fixedly connected to the bottom end of the connecting column 51 slides synchronously inside the slide groove 55. The combination of the slider 54 and the slide groove 55 guides the movement of the die 2 and makes the die 2 move more smoothly.

[0044] Further, the release assembly includes a groove 66, which is provided at the top of the card block 63, and the groove 66 cooperates with the plug block 67, and the plug block 67 is inserted into the interior of the storage cavity 62. A movable groove 68 is provided on the right side of the plug block 67, and a guide rod 69 is fixedly connected to the interior of the movable groove 68. A movable block 70 is slidably connected to the outer side of the guide rod 69. The movable block 70 is fixedly connected to the inner wall of the storage cavity 62, and a second spring 71 is also provided on the outer side of the guide rod 69. The two ends of the second spring 71 are respectively connected to the inner wall of the storage cavity 62. The top of the guide rod 69 is fixedly connected to the inner wall of the movable groove 68, and a connecting key groove 78 is provided at the outer side of the rotating shaft 79 near the middle. The connecting key groove 78 is rotatably connected to the connecting ring 77, and the connecting ring 77 is fixedly connected to the inner wall of the rear side of the movable rod 74. The front end of the movable rod 74 is sleeved on the outer side of the fixed rod 75, and the left side of the fixed rod 75 is fixedly connected to the inner wall of the movable cavity 76. The bottom end of the movable rod 74 is fixedly connected to a push block 72, and the right side of the bottom end of the push block 72 is rotatably connected to a roller 73.

[0045] During operation, when the connection between the upper die seat 1 and the concave die 2 is to be released, the rotating button 86 is first pulled to the right. Under the action of the pulling force, the rotating button 86 drives the movable rod 74 to move synchronously through the rotating shaft 79, the connecting key slot 78 and the connecting ring 77. When the movable rod 74 moves, it drives the fixedly connected push block 72 to move synchronously, so that the push block 72 drives the roller 73 to squeeze the inclined surface opened at the top of the plug block 67. The sliding friction between the push block 72 and the plug block 67 is converted into rolling friction through the roller 73, which effectively reduces the friction resistance, so that the push block 72 is smoother when pushing the plug block 67 downward. The plug block 67 moves downward under the action of the extrusion force and the bottom end is inserted into the inside of the groove 66, pulling the card block 63 to move into the inside of the storage cavity 62 The engagement with the first clamping groove 64 is released, and the auxiliary fixing effect of the clamping block 63 on the connection between the upper die seat 1 and the concave die 2 is released. When the rotating knob 86 is pulled to drive the rotating shaft 79 to move, the sliding block 83 fixedly connected to the inner wall of the sleeve groove 80 slides synchronously inside the sliding groove 84. The sliding block 83 and the sliding groove 84 are combined to limit the moving distance of the rotating shaft 79 to prevent the rotating shaft 79 from moving excessively and coming out of the sleeve groove 80. When the rotating shaft 79 moves, the third spring 82 is also pulled to produce elastic deformation. The restoring force of the third spring 82 plays an effect of restoring the rotating shaft 79, the rotating knob 86, the movable rod 74, the push block 72 and the roller 73 to their original positions after the pulling of the rotating knob 86 is stopped.

[0046] When the plug block 67 is squeezed, the movable block 70 slidably connected to the outside of the guide rod 69 moves synchronously inside the movable groove 68, and at the same time squeezes the second spring 71, causing the second spring 71 to produce elastic deformation. The cooperation of the guide rod 69 and the movable groove 68 can limit the movement distance of the plug block 67 to prevent the plug block 67 from moving excessively and escaping from the storage chamber 62. The restoring force of the second spring 71 can automatically reset the plug block 67 after the squeezing force disappears to release the squeezing of the block 63.

[0047] Further, the rotation limit assembly includes a limit sleeve 87, which is sleeved on the outer side of the rotation button 86, and the left side of the limit sleeve 87 is fixedly connected with a front clamping tooth 88, which is engaged with a rear clamping tooth 89, and the rear clamping tooth 89 is fixedly connected with the right side of the upper mold base 1. The left side of the limit sleeve 87 is also fixedly connected with a movable sleeve 90, which is slidably connected to the inside of a connecting groove 91, and the connecting groove 91 is provided on the right side of the upper mold base 1. A clamping ring 92 is fixedly connected to the inner wall of the connecting groove 91, and a second clamping groove 93 is provided on the inner wall of the movable sleeve 90. The clamping ring 92 is made of silicone rubber, and the clamping ring 92 is engaged with the second clamping groove 93.

[0048] During operation, when the rotating knob 86 is to be rotated, the limiting sleeve 87 is pulled to the right. Under the action of the pulling force, the limiting sleeve 87 drives the front locking tooth 88 and the movable sleeve 90 to move to the right. At this time, the front locking tooth 88 is released from the state of being engaged with the rear locking tooth 89, thereby releasing the limit on the rotation of the rotating knob 86. When the movable sleeve 90 moves to the right, the inner wall of the second clamping groove 93 squeezes the clamping ring 92 fixedly connected to the inner wall of the connecting groove 91, so that the clamping ring 92 made of rubber material is squeezed under the action of the squeezing force. Due to elastic deformation, when the movable sleeve 90 moves to the right to the limit, the inner wall of the second slot 93 no longer squeezes the snap ring 92. At this time, the second slot 93 returns to the state of being engaged with the snap ring 92, and the positions of the movable sleeve 90, the limiting sleeve 87 and the front locking tooth 88 are fixed, so that the front locking tooth 88 remains separated from the rear locking tooth 89. When the rotation of the rotating knob 86 is to be limited, the limiting sleeve 87 is pushed to move to the left to the limit so that the front locking tooth 88 can be restored to the engaged state with the rear locking tooth 89.
