[0026] like Figures 1 to 6 As shown, the utility model is a stamping die for a new energy automobile charging interface that is convenient for discharging, comprising: a frame 1, a stamping mechanism that is convenient for stamping a workpiece, and a discharging mechanism that is convenient for discharging the stamped workpiece;

[0027] The discharging mechanism includes: a top plate 16, and a moving assembly that drives the top plate 16 to move up and down; the moving assembly includes: a hydraulic rod 2 fixedly installed on the top of the inner cavity of the frame 1, a movable plate 3 fixedly installed on the movable end of the hydraulic rod 2, a connecting plate 7 symmetrically fixedly installed at the bottom of the movable plate 3, a first trapezoidal block 8 fixedly installed on one side of the connecting plate 7, a transverse plate fixedly installed on the inner wall of the frame 1, a linkage plate 10 arranged at the bottom of the transverse plate, a clamping rod 15 fixedly installed at the top center of the linkage plate 10, the top end of the clamping rod 15 passes through the center of the transverse plate and the bottom of the lower mold 9, and extends to the inner cavity of the lower mold 9, the top plate 16 is fixedly installed at the top end of the clamping rod 15, and a linkage unit that drives the linkage plate 10 to move, and the linkage plate 1 0 is a limiting unit for limiting, a lower mold 9 is fixedly installed at the center of the top of the horizontal plate, and the top plate 16 is located inside the mold cavity of the lower mold 9. The linkage unit includes: a fixed shell 11 symmetrically fixedly installed on the top of the linkage plate 10, a fixed rod 20 fixedly installed in the inner cavity of the fixed shell 11, a sliding plate 12 sleeved on the outer edge of the fixed rod 20, a second trapezoidal block 13 and a third trapezoidal block 19 fixedly installed on one side of the sliding plate 12, a linkage spring 21 fixedly installed between the sliding plate 12 and the inner cavity of the fixed shell 11, a U-shaped plate 17 symmetrically fixedly installed at the bottom of the horizontal plate, a roller 18 hingedly installed in the inner cavity of the U-shaped plate 17, and a reset spring 22 fixedly installed between the linkage plate 10 and the fixed shell 11;

[0028] When in use, the workpiece is placed on the top of the top plate 16, and the workpiece is punched by the punching mechanism. When the movable plate 3 moves downward, the two connecting plates 7 can be driven to move downward, and the adjacent first trapezoidal blocks 8 can be driven to move downward through the two connecting plates 7. When the inclined surface of the first trapezoidal block 8 fits with the inclined surface of the adjacent second trapezoidal block 13, the two second trapezoidal blocks 13 can be driven to move outward, and the sliding plates 12 can be driven to move outward through the second trapezoidal blocks 13, and the two linked springs 21 can be stretched through the sliding plates 12. When the first trapezoidal block 8 moves below the adjacent second trapezoidal block 13, the adjacent sliding plates 12 can be driven to reset through the elastic force of the two linked springs 21.

[0029] After the stamping is completed, the movable plate 3 is driven upward by the hydraulic rod 2, and the two connecting plates 7 are driven upward by the Rongguang movable plate 3, and the adjacent first trapezoidal block 8 is driven upward by the connecting plate 7. When the horizontal plane at the top of the first trapezoidal block 8 is in contact with the horizontal plane at the bottom of the adjacent second trapezoidal block 13, the adjacent second trapezoidal block 13 is driven upward by the first trapezoidal block 8, and the adjacent sliding plates 12 are driven upward by the two second trapezoidal blocks 13, so that the interlocking plate 10 can be driven to move upward, and the clamping rod 15 is driven upward by the interlocking plate 10, and the top plate 16 is driven upward by the clamping rod 15, and the workpiece in the mold cavity of the lower mold 9 can be ejected by the top plate 16. At this time, the upward movement of the interlocking plate 10 can drive the reset spring 22 to be compressed. When the sliding plate 12 continues to move upward, the inclined surface of the third trapezoidal block 19 will be aligned with the adjacent The bottom of the roller 18 fits, and the roller 18 squeezes the third trapezoidal block 19, so that the third trapezoidal block 19 drives the adjacent sliding plate 12 to move to both sides, and the sliding plate 12 drives the adjacent second trapezoidal block 13 to move to both sides, and drives the adjacent linkage spring 21 to be compressed. Since the two second trapezoidal blocks 13 move to both sides, they will be separated from the adjacent first trapezoidal block 8. When the second trapezoidal block 13 is separated from the adjacent first trapezoidal block 8, the elastic force of the roller 18 can drive the linkage plate 10 to reset, and then the top plate 16 to reset, and the elastic force of the linkage spring 21 can drive the sliding plate 12 to reset, so that the device can automatically eject the stamped workpiece in the mold cavity of the lower mold 9, solving the problem that the charging interface is easily stuck in the mold cavity after stamping and is inconvenient to remove, and there is no need for manual removal, thereby improving work efficiency.

[0030] The limiting unit includes: slide bars fixedly installed on both sides of the linkage plate 10, a slide groove is opened on the inner wall of the frame 1, and the slide bars are located in the corresponding slide groove cavities. The sliding bars slide in the slide groove cavities to limit the moving direction of the linkage plate 10.

[0031] The stamping mechanism includes: an upper die 4 fixedly installed at the bottom center of the movable plate 3, a positioning component that positions the upper die 4, and an extrusion component that is fixed when the new energy charging interface of the automobile is stamped. By starting the hydraulic rod 2, the movable plate 3 is driven downward by the hydraulic rod 2, and the upper die 4 is driven downward by the movable plate 3. The workpiece can be stamped and formed by the downward movement of the upper die 4.

[0032] The positioning assembly includes: a positioning rod 6 installed through the side wall of the movable plate 3, both ends of the positioning rod 6 are fixedly connected to the inner wall of the frame 1. During the movement of the movable plate 3, the positioning rods 6 arranged at the four corners of the movable plate 3 can play a positioning role in the movement of the movable plate 3, and then play a positioning role in the upper mold 4, avoiding the displacement of the upper mold 4 when moving, and improving the accuracy of the upper mold 4 when stamping.

[0033] The extrusion assembly includes: a mounting hole opened at the bottom of the upper die 4, an extrusion rod 5 inserted and installed in the inner cavity of the mounting hole, and a clamping spring 14 fixedly installed between the extrusion rod 5 and the inner cavity of the mounting hole. Before the upper die 4 punches the workpiece, the bottom end of the extrusion rod 5 first fits the workpiece. When the upper die 4 continues to move downward, the clamping spring 14 is compressed by the upper die 4. The clamping spring 14 can generate a downward thrust on the extrusion rod 5, so that the four groups of extrusion rods 5 can extrude and fix the workpiece, thereby improving the stability of the workpiece during stamping. The four groups of extrusion rods 5 are distributed at the four corners of the bottom of the upper die 4, so that the four corners of the workpiece can be extruded and fixed, so that the workpiece is subjected to uniform extrusion force, thereby improving the extrusion and fixing effect.

[0034] Working principle: When in use, the workpiece is placed on the top of the top plate 16. At this time, the workpiece is punched by the punching mechanism, and the punched workpiece can be discharged by the discharge mechanism, so that the device can automatically eject the punched workpiece in the cavity of the lower die 9, solving the problem that the charging interface is easily stuck in the cavity after punching and is inconvenient to remove, and there is no need for manual removal, thereby improving work efficiency.
