DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application discloses a mold for making a blank of an automobile connecting rod. Figure 1 , Figure 3 , Figure 4 As shown, it includes a base 1, an upper mold 3 is arranged above the base 1, a mounting plate 4 is arranged on the upper end surface of the upper mold 3, a lower mold 2 is arranged below the upper mold 3, a mold cavity 14 is arranged on the lower mold 2, a bottom plate 15 is slidably installed in the mold cavity 14, a support plate 16 is arranged below the bottom plate 15, the support plate 16 is fixedly connected to the lower end surface of the lower mold 2, an adjusting member is arranged between the support plate 16 and the bottom plate 15, and the adjusting member includes a hydraulic cylinder 17, one end of the hydraulic cylinder 17 is fixedly connected to the base 1, and the other end is fixedly connected to the support plate 16. After the automobile connecting rod is processed and formed, the hydraulic cylinder 17 is driven to work, and the hydraulic cylinder 17 drives the base 1 to slide in the mold cavity 14 and pushes the automobile connecting rod to move in the mold cavity 14, so as to achieve the purpose of pushing the automobile connecting rod out of the mold cavity 14, which is convenient for the staff to pick up.

[0023] See also Figure 1 , Figure 4 A rotating shaft 5 is fixedly installed on the lower mold 2, and the rotating shaft 5 is rotatably connected to the base 1. A gear 6 is installed at one end of the rotating shaft 5, and a rack 8 is arranged on one side of the gear 6. The rack 8 meshes with the gear 6 for transmission. A limiting plate 11 is arranged on one side of the rack 8, and one end of the limiting plate 11 is fixedly connected to the base 1, and the other end is slidably connected to the lower mold 2. The rack 8 is slidably connected to the limiting plate 11, and the position of the rack 8 is limited by the limiting plate 11 to prevent the rack 8 from separating from the gear 6 during the movement, which affects the normal operation and safety of the device and the stability of the meshing between the rack 8 and the gear 6.

[0024] See also Figure 1 , Figure 2 A fixed shaft 12 is fixedly installed on the limiting plate 11, a fixed groove 13 is provided on the gear 6, the fixed shaft 12 is rotatably connected to the fixed groove 13, the rack 8 is slidably connected to the upper mold 3 through a fixing part, the fixing part includes a fixing plate 7, and the fixing plate 7 is fixedly connected to the upper mold 3 through screws. The fixed shaft 12 cooperates with the limiting plate 11 to limit the position of the gear 6 to prevent the gear 6 from shaking and affecting the meshing of the gear 6 and the rack 8.

[0025] See also Figure 1 The fixing plate 7 is slidably connected with the rack 8, and a baffle 9 is installed on the rack 8. A fixing bolt 10 is installed on the baffle 9. The fixing bolt 10 passes through the baffle 9 and is threadedly connected with the baffle 9. By driving the fixing bolt 10 to rotate, the fixing bolt 10 moves on the baffle 9, thereby releasing the fixation of the baffle 9, so that the baffle 9 can slide on the rack 8. By driving the fixing bolt 10 in the reverse direction to rotate, the fixing bolt 10 squeezes the rack 8 to fix the baffle 9, so as to achieve the effect of adjusting the position of the baffle 9. When the upper mold 3 is driven away from the lower mold 2, the upper mold 3 drives the fixing plate 7 to move, and the fixing plate 7 drives the baffle 9 to move, and the baffle 9 drives the rack 8 to move, and the rack 8 drives the meshing gear 6 to rotate. When the gear 6 rotates, it drives the lower mold 2 to rotate, so as to achieve the effect of adjusting the angle of the lower mold 2, which is convenient for the staff to pick up.

[0026] The implementation principle of a blank making mold for an automobile connecting rod in an embodiment of the present application is as follows: after the automobile connecting rod is processed and formed, the upper mold 3 is controlled to rise and separate from the lower mold 2. When the upper mold 3 rises, it drives the fixed plate 7 to move with it. After the fixed plate 7 moves to the preset position, it drives the baffle 9 to move with it. The baffle 9 drives the rack 8 to move. When the rack 8 moves, it slides with the limit plate 11 and drives the gear 6 to rotate. The gear 6 drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, it drives the lower mold 2 to rotate and adjusts the lower mold 2 to a specified angle. At the same time, the hydraulic cylinder 17 is driven to work. The hydraulic cylinder 17 drives the base 1 to slide in the mold cavity 14 and directly ejects the automobile connecting rod in the mold cavity 14, which is convenient for the staff to pick up. The baffle 9 can be released by driving the fixing bolt 10 to rotate, and the position of the baffle 9 can be adjusted.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
