The left end of the chassis is rotatably connected with a material roller, and the right end of the chassis is rotatably connected with a winding roller. Symmetrically fixed to the front and rear ends of the winding roller are ratchets. A through groove is provided in the middle of the chassis, and symmetrically fixed to the left and right sides of the chassis are support rods. Lifting components are symmetrically arranged on the front and rear sides of the chassis, and a backing plate is arranged above the lifting components. The top of the support rod is fixedly connected with a cross beam, and a lifting rod is fixedly connected below the cross beam.

The piston 64 is slidably connected to the bottom end inside the supercharging chamber 65, and the outside of the piston 64 is in close fit with the inner wall of the bottom end of the supercharging chamber 65. A spray outlet 66 is opened on the left side of the supercharging chamber 65. An atomizing nozzle 67 is fixedly connected inside the spray outlet 66, and a baffle 68 is arranged inside the spray outlet 66. Sealing rings 69 are arranged on both the left and right sides of the baffle 68. The sealing rings 69 are fixedly connected to the inner wall of the spray outlet 66. The bottom end of the baffle 68 is inserted into the inside of the moving chamber 70. The moving chamber 70 is opened at the bottom end of the spray outlet 66. A push block 71 is arranged inside the moving chamber 70. A sliding groove 72 is opened at the bottom end of the push block 71. A sliding block 73 is slidably connected inside the sliding groove 72. The sliding block 73 is fixedly connected to the bottom end inside the moving chamber 70. A second spring 74 is arranged inside the sliding groove 72. A first magnet 75 is fixedly connected to the left side of the push block 71. The first magnet 75 cooperates with a second magnet 76. The second magnet 76 is fixedly connected to a position near the middle on the right side of the ejecting block 53; The cross-section of the supercharging chamber 65 is designed in a "U" shape. The supercharging chamber 65 is opened inside the lower mold 3, and lubricating oil is filled inside the supercharging chamber 65. The piston 64 is made of silicone rubber. Two sets of through holes 85 are opened on the ejecting block 53. The positions of the through holes 85 correspond to the spray outlet 66; The side of the second spring 74 close to the sliding block 73 is fixedly connected to the sliding block 73. The side of the second spring 74 far from the sliding block 73 is fixedly connected to the inner wall of the sliding groove 72; A slope is opened on the right side of the push block 71, and the top end of the push block 71 abuts against the bottom end of the baffle 68; The oil storage assembly includes an oil storage chamber 77. The oil storage chamber 77 is opened at the top end of the supercharging chamber 65. A sealing assembly is arranged at the bottom end of the oil storage chamber 77. An oil injection hole 82 is opened at the top end of the oil storage chamber 77. A sealing plug 83 is inserted into the inside of the oil injection hole 82. An exhaust port 84 is opened at the top end of the oil storage chamber 77; A slope is opened at the bottom end of the oil storage chamber 77, and the oil storage chamber 77 is communicated with the supercharging chamber 65. The bottom end of the oil storage chamber 77 is designed in a circular shape; During operation, when the upper mold 2 is lifted up after the connection terminal is stamped and formed, the ejector block 53 inserted in the storage cavity 52 moves upward synchronously with the movement of the upper mold 2 under the action of the restoring force of the first spring 54. When the ejector block 53 moves upward, the stamped connection terminal in the molding groove 51 is ejected upward. At the same time, the rack 58 fixedly connected to the inner wall of the moving groove 57 opened on the ejector block 53 also moves upward synchronously with the movement of the ejector block 53, and the first gear 59 is rotated. The rotation of the first gear 59 drives the meshed second gear 60 to rotate synchronously, and the The second gear 60 has the effect of decelerating and increasing the torque. The rotation of the second gear 60 drives the fixedly connected screw 62 to rotate synchronously, so that the screw sleeve 63 threadedly connected to the outside thereof moves, and the piston 64 moves toward the inside of the boosting chamber 65, and the oil in the boosting chamber 65 is pressurized. When the ejection block 53 moves upward to the limit, the through hole 85 opened on the ejection block 53 is aligned with the ejection port 66, and the second magnetic block 76 fixedly connected to the ejection block 53 is on the same horizontal line as the first magnetic block 75. At this time, the second magnetic block 76 attracts the first magnetic block 75, so that the first magnetic block 75 Under the action of magnetic force, the sliding block 73 moves to the left side of the active cavity 70, and drives the push block 71 to move synchronously. When the push block 71 moves to the left, the sliding block 73 slides synchronously in the sliding groove 72, and squeezes the second spring 74, so that the second spring 74 produces elastic deformation. After the push block 71 moves to the left, the baffle 68 loses the support of the push block 71, and moves downward under the action of gravity to enter the active cavity 70. At this time, the baffle 68 releases the obstruction of the oil, and the oil is atomized and sprayed into the inside of the spray port 66 through the atomizing nozzle 67 under the action of pressure. The oil is evenly sprinkled on the inside of the upper mold 2 through the through hole 85 opened on the ejection block 53. The through hole 85 effectively avoids the blocking of the ejected oil. The atomizing nozzle 67 is equipped with a one-way valve. After the pressure inside the boosting chamber 65 is reduced, the atomizing nozzle 67 is automatically closed to avoid the situation of oil dripping. The technology used by the atomizing nozzle 67 is a mature existing technology, so it is not described in detail in this case. For details, please refer to the Chinese patent with publication number CN110711655A. The atomizing nozzle 67 used in this case is consistent with its principle and structure; When the ejection block 53 is squeezed and moves downward by the upper mold 2, the second magnetic block 76 gradually loses its attraction to the first magnetic block 75. At this time, the push block 71 returns to its original position under the restoring force of the second spring 74, and pushes the baffle 68 upward through the inclined surface opened at the top of its left side, so that the baffle 68 also returns to its original position synchronously, so that the spray port 66 returns to the closed state, and the oil cannot flow out through the atomizing nozzle 67, so that the piston 64 can smoothly pressurize the oil in the boosting chamber 65; When the ejector block 53 moves upward, it drives the fixedly connected slider 55 to slide synchronously inside the chute 56. The slider 55 and the chute 56 guide the movement of the ejector block 53 and limit the moving distance of the ejector block 53 to prevent the ejector block 53 from disengaging from the inside of the storage cavity 52.

[0022] Further, the sealing assembly includes an oil passage ring 78 fixedly connected to a position near the bottom end of the inner wall of the oil storage cavity 77. The oil passage ring 78 is designed in a ring shape. A dropping ring 79 is fixedly connected to the bottom end of the inner wall of the oil storage cavity 77. A oil passage plate 80 is arranged at the top end of the dropping ring 79. Flow channels are formed on the oil passage plate 80. A sealing gasket 81 is fixedly connected to the top end of the oil passage plate 80. The sealing gasket 81 is made of silicone rubber. During operation, when the pressure of the oil liquid in the pressure increasing cavity 65 increases under the pushing force of the piston 64, the oil liquid pushes the oil passage plate 80 to move upward under the action of the pressure, so that the sealing gasket 81 fixedly connected to the oil passage plate 80 is inserted into the inside of the oil passage ring 78, closing the connection between the oil storage cavity 77 and the pressure increasing cavity 65, and preventing the oil liquid in the pressure increasing cavity 65 from flowing reversely into the inside of the oil storage cavity 77 and spraying out from the exhaust port 84 at the top end of the oil storage cavity 77. When the upper die 2 descends to stamp the connector terminal, the ejector block 53 is extruded by the upper die 2 and moves into the inside of the storage cavity 52. At this time, the rack 58 drives the first gear 59 to rotate reversely, and the first gear 59 drives the second gear 60 and the screw 62 to rotate reversely, so that the nut 63 threadedly connected to the outside of the screw 62 moves reversely, driving the piston 64 to return to its original position. During the process of the piston 64 moving back to its original position, the volume inside the pressure increasing cavity 65 gradually increases and a negative pressure is generated inside the pressure increasing cavity 65. Under the action of the negative pressure suction force, the oil passage plate 80 is pulled to move downward, so that the sealing gasket 81 releases the blockage of the oil passage ring 78. At this time, the oil liquid inside the oil storage cavity 77 enters into the inside of the pressure increasing cavity 65 through the oil passage ring 78 and the oil passage plate 80 to supplement the oil liquid inside the pressure increasing cavity 65.

[0023] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
