[0017] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.
[0018] As shown in Figures 1 - 3, a control arm forging die includes a die base 10, characterized in that: a die groove 11 is formed on the upper end surface of the die base 10, an air pressure chamber 18 and a sliding groove 19 are formed in the die base 10, and a buffer assembly is further provided in the air pressure chamber 18 and the sliding groove 19. A groove is formed at the bottom of the die groove 11, and a top plate 12 is located in the groove. The top plate 12 is the same size as the groove, and the groove communicates with the air pressure chamber 18. The buffer assembly includes a sealing block 14 that slides in the air pressure chamber 18. A top plate 12 is fixed to the sealing block 14 through a connecting rod 13. A guide rod 17 is fixed to the bottom of the air pressure chamber 18. An auxiliary plate 16 slides on the guide rod 17, and the auxiliary plate 16 also slides in the air pressure chamber 18. A slider 20 slides in the sliding groove 19. A lead screw 21 is threadedly connected inside the slider 20. The lead screw 21 passes through the die base 10 to the outside, and a rotating handle is fixed at the outside of the lead screw 21. An upper chamber is formed between the sealing block 14 and the auxiliary plate 16, and a lower chamber is formed between the auxiliary plate 16 and the slider 20. A guide groove 15 is formed on one end face of the sealing block 14. The guide groove 15 passes through the connecting rod 13 into the top plate 12. The guide groove 15 cooperates with the guide rod 17. A raised disc is provided in the middle of the guide rod 17, and the raised disc is used to limit the position of the auxiliary plate 16.
[0019] The air pressure chamber 18 and the sliding groove 19 communicate with each other. The air pressure chamber 18 is vertically arranged, and the sliding groove 19 is horizontally arranged. The sliding groove 19 is square-shaped. An air port 23 is further formed at the bottom of the connection between the sliding groove 19 and the air pressure chamber 18. A one-way ball 22 is movably arranged in the air port 23, and the one-way ball 22 can be used to limit the one-way flow of air.
[0020] During use, place the die components in the die groove 11, and then start die casting. During die casting, press down the top plate 12 to make the top plate 12 enter the groove. A complete die groove can be formed in the die groove 11. The top plate 12 drives the sealing block 14 through the connecting rod 13 to compress the upper chamber of the air pressure chamber 18, and then compresses the lower chamber through the auxiliary plate 16, so that the air in the entire air pressure chamber 18 is compressed. After die casting, the air chamber rebounds, pushing the top plate 12 to automatically eject the die-cast parts, which greatly facilitates the staff to take.
[0021] When a certain amount of air leakage occurs in the air pressure chamber 18 due to multiple uses, the lead screw 21 can be rotated to move the slider 20 to one side of the guide rod 17, so that the air in the air pressure chamber 18 can reach the normal density. After the slider 20 reaches the bottom, reverse rotation can make the outside air enter the sliding groove 19 through the one-way ball 22 and the air port 23 to achieve balance, so as to adjust the air density in the air pressure chamber 18 for the next time.
[0022] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model.
