DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 to 7 shown, the present utility model provides a stamping die for automotive parts with a waste collection function, including a bottom die 1. Four groups of guide rods 3 are fixedly installed at the four corners of the top of the bottom die 1. A top die 2 is sleeved on the outer walls of the four groups of guide rods 3. The bottom of the top die 2 and the top of the bottom die 1 are elastically connected by a spring 4.

[0029] Connecting blocks 5 are fixedly installed on both the left and right sides of the top die 2. Piston cylinders 6 are fixedly installed on both the left and right sides of the bottom die 1. Piston rods 7 are fixedly installed at the bottoms of the two connecting blocks 5. Air outlet valves 8 are fixedly installed at the bottoms of the two piston cylinders 6. A plug one 9 is movably installed inside the air outlet valve 8. The bottom of the plug one 9 and the inner wall of the air outlet valve 8 are elastically connected by a return spring one 10. An air outlet 11 is fixedly opened on the left side of the air outlet valve 8.

[0030] Suction valves 12 are fixedly installed on both the left and right sides of the inner wall of the bottom die 1. The suction valves 12 communicate with the piston cylinders 6. A sleeve 13 is fixedly installed inside the suction valve 12. A plug two 14 is movably sleeved inside the sleeve 13. The bottom of the plug two 14 and the inner wall of the suction valve 12 are elastically connected by a return spring two 15. An air suction port 16 is opened at the top of the suction valve 12.

[0031] Before performing the stamping operation, the staff first externally connect a cylinder to the top of the top die 2, place the metal material between the bottom die 1 and the top die 2, and then start the cylinder to press down the top die 2 to stamp the metal material. When the top die 2 presses down, the connecting block 5 will drive the piston rod 7, causing the piston rod 7 to squeeze the air inside the piston cylinder 6 downward. At this time, the pressure inside the piston cylinder 6 increases, forcing the plug one 9 to squeeze the return spring one 10 downward, and the bottom of the piston cylinder 6 is opened, allowing the gas inside the piston cylinder 6 to be discharged through the air outlet 11. After the air pressure inside the piston cylinder 6 returns to normal, the elastic potential energy of the return spring one 10 drives the plug one 9 to reset and seal the bottom of the piston cylinder 6 again. At this time, the stamping is completed, and the staff drives the cylinder to reset the top die 2. When the top die 2 resets upward, the piston rod 7 will perform an upward piston movement inside the piston cylinder 6 to suck in air. At this time, the conical part at the top of the plug one 9 seals the bottom of the piston cylinder 6, causing the plug two 14 to receive suction, so that the plug two 14 is received downward into the sleeve 13, and external gas is sucked in through the air suction port 16. When sucking in air through the air suction port 16, a negative pressure environment will be generated inside the bottom die 1, thereby sucking the waste material stamped inside the bottom die 1 into the inside of the bottom die 1 to prevent the waste material from clogging or jumping.

[0032] Through the downward stamping of the top die 2, the air inside the piston cylinder 6 squeezes the plug one 9, forcing the plug one 9 to open the air outlet 11 downward. At this time, the gas is discharged through the air outlet 11. Through the upward reset of the top die 2, the plug two 14 is received downward into the sleeve 13, and the piston cylinder 6 sucks in external gas through the air suction port 16. Compared with traditional devices, when the top die 2 resets, through the cooperation of the piston cylinder 6 and the piston rod 7, a negative pressure environment is provided inside the bottom die 1, thereby attracting the waste material stamped, preventing the waste material from clogging or jumping, effectively improving the collection efficiency, and ensuring safety during stamping.

[0033] Among them, fixed plates 20 are fixedly installed at both the front and rear ends of the bottom of the bottom die 1. A fixed head 21 is movably installed inside the two fixed plates 20. The fixed head 21 and the inner wall of the fixed plate 20 are elastically connected by a return spring three 22. An installation plate 18 is detachably installed between the two fixed heads 21. A collection shell 17 is fixedly installed on the top of the installation plate 18, and the collection shell 17 is located inside the bottom die 1.

[0034] During the stamping operation, the waste generated by the stamping will fall into the collecting shell 17 and be collected. After the operation is completed, the staff uses the control rod 24 to pull the fixed head 21 to both sides to squeeze the reset spring three 22. At this time, the fixed head 21 leaves the inside of the mounting groove 19, and the staff can remove the mounting plate 18 to centrally process the waste in the collecting shell 17. After the processing is completed, the staff resets the mounting plate 18 and releases the control rod 24. Through the elastic potential energy of the reset spring three 22, the fixed head 21 will move inward to the inside of the mounting groove 19 and abut against the inner wall of the mounting groove 19 to complete the fixation and installation of the mounting plate 18.

[0035] By moving the fixed head 21 to both sides through the control rod 24, the reset spring three 22 is squeezed, and the fixed head 21 leaves the installation groove 19, so that the staff can remove the installation plate 18 and centrally process the waste in the collection shell 17. Compared with the traditional device, the device cooperates with the reset spring three 22 and the fixed head 21, so that the staff can easily disassemble and install the collection shell 17 through the control rod 24, which effectively improves the work efficiency of waste collection and reduces the workload.

[0036] Among them, the top of the plug 9 is conical, and the plug 9 seals the bottom of the piston cylinder 6 through the elastic potential energy of the return spring 10.

[0037] The top of the second plug 14 is conical, and the second plug 14 seals the air inlet 16 through the elastic potential energy of the second return spring 15 .

[0038] The bottoms of the two groups of piston rods 7 are movably mounted inside the piston cylinder 6 , and the bottoms of the piston rods 7 are tightly fitted to the inner wall of the piston cylinder 6 .

[0039] The piston rod 7 performs piston motion inside the piston cylinder 6 , thereby providing a negative pressure environment inside the bottom mold 1 .

[0040] The front and rear ends of the outer wall of the mounting plate 18 are both provided with mounting grooves 19 , and the two sets of fixing heads 21 and the inner walls of the mounting grooves 19 are in contact with each other.

[0041] Through the elastic potential energy of the reset spring 3 22 , the fixing head 21 will move inward to the inside of the mounting groove 19 and abut against the inner wall of the mounting groove 19 , thereby completing the fixing and installation of the mounting plate 18 .

[0042] A movable groove 23 is formed at the bottom of the fixing plate 20 , and a control rod 24 is fixedly installed at the bottom of the fixing head 21 . One end of the control rod 24 passes through the movable groove 23 and is located at the bottom of the fixing plate 20 .

[0043] There are four groups of springs 4 , all of which are elastically arranged on the outer walls of the four groups of guide rods 3 .

[0044] Responsible for the reset operation of top die 2 after stamping is completed.

[0045] The working principle and use process of this utility model:

[0046] Before the stamping operation, the staff first connects the top of the top die 2 to the external cylinder, and places the metal material between the bottom die 1 and the top die 2, and then starts the cylinder to press the top die 2 downward to stamp the metal material. When the top die 2 is pressed downward, the connecting block 5 will drive the piston rod 7, so that the piston rod 7 squeezes the air inside the piston cylinder 6 downward. At this time, the pressure in the piston cylinder 6 increases, forcing the plug 9 to squeeze the return spring 10 downward, and the bottom of the piston cylinder 6 is opened, so that the gas in the piston cylinder 6 is discharged through the outlet 11. After the air pressure in the piston cylinder 6 is normal, the elastic potential energy of the return spring 10 drives the plug 9 to reset. The bottom of the piston cylinder 6 is sealed again. At this time, the stamping is completed, and the staff drives the cylinder to reset the top mold 2. When the top mold 2 is reset upward, the piston rod 7 will perform an upward piston movement inside the piston cylinder 6 to inhale air. At this time, the conical part on the top of the plug 1 9 seals the bottom of the piston cylinder 6, so that the plug 2 14 receives suction, so that the plug 2 14 is downwardly retracted into the sleeve 13, and the external gas is inhaled through the air intake port 16. When the air intake port 16 inhales, a negative pressure environment is generated inside the bottom mold 1, thereby sucking the waste material under stamping into the bottom mold 1 to prevent waste material blockage or material jumping.

[0047] During the stamping operation, the waste generated by the stamping will fall into the collecting shell 17 and be collected. After the operation is completed, the staff uses the control rod 24 to pull the fixed head 21 to both sides to squeeze the reset spring three 22. At this time, the fixed head 21 leaves the inside of the mounting groove 19, and the staff can remove the mounting plate 18 to centrally process the waste in the collecting shell 17. After the processing is completed, the staff resets the mounting plate 18 and releases the control rod 24. Through the elastic potential energy of the reset spring three 22, the fixed head 21 will move inward to the inside of the mounting groove 19 and abut against the inner wall of the mounting groove 19 to complete the fixation and installation of the mounting plate 18.
