Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

The present application is that a lower die 2 is rotatably connected to a support frame 1, a slide seat 3 is slidably connected to the support frame 1, an upper die 4 cooperating with the lower die 2 is installed on the slide seat 3, a driving component 5 for driving the lower die 2 to flip is installed on the slide seat 3, a limiting component 6 for limiting the rotation of the lower die 2 is installed on the support frame 1, and a hydraulic cylinder 7 for driving the slide seat 3 to move is installed on the support frame 1. After the upper die 4 and the lower die 2 punch out a workpiece, the hydraulic cylinder 7 drives the upper die 4 to move upward through the slide seat 3, and the upper die 4 drives the lower die 2 to flip through the driving component 5, and the stamping surface of the lower die 2 rotates from upward to downward, and the metal residue remaining on the upper end surface of the lower die 2 is dumped down, so that the residue The slag is separated from the lower die 2, and the workpiece on the lower die 2 will fall down together with the residue due to the overturning, which reduces the steps for the operator to take the workpiece and improves safety. Then the hydraulic cylinder 7 drives the upper die 4 to move downward through the slide 3, and the driving assembly 5 drives the lower die 2 to rotate in the opposite direction and return to the starting position. Then the limit assembly 6 locks the lower die 2 to prevent the lower die 2 from overturning during the stamping process. Then the operator places the plate on the lower die 2 and the upper die 4, and the upper die 4 continues to move downward for stamping, thereby automatically cleaning the metal residue in the lower die 2, reducing the damage to the workpiece during the next stamping, improving the product qualification rate, reducing labor intensity, and improving safety.

[0024] Example 2: Based on Example 1, Figure 2 and Figure 3To explain, the driving assembly 5 includes an L frame 51, the slide 3 is equipped with the L frame 51, the L frame 51 is equipped with a rack 52, and the lower die 2 is equipped with a gear 53 meshing with the rack 52. In the present application, the L frame 51 is installed on the slide 3, the rack 52 is installed on the L frame 51, and the gear 53 meshing with the rack 52 is installed on the lower die 2. When the slide 3 moves up, the L frame 51 drives the rack 52 to move upward. When the L frame 51 does not exceed the position of the gear 53, the lower die 2 cannot deflect. Then, the L frame 51 continues to move up, the rack 52 meshes with the gear 53, and the upwardly moved rack 52 drives the lower die 2 to rotate clockwise and flip by meshing with the gear 53. The lower die 2 dumps out the stamped workpiece and metal residues, and then only one power source is needed to automatically clean the stamped workpiece and the metal residues in the lower die 2, thereby reducing labor intensity, improving product qualification rate, reducing production costs, and improving safety.

[0025] Example 3: Based on Example 1, Figure 2 and Figure 4 To explain, the limit assembly 6 includes a limit block 61, the limit block 61 is slidably connected to the support frame 1, the limit block 61 and the support frame 1 are connected by a spring, a limit hole 62 for the limit block 61 to be inserted is provided on the lower die 2, a squeeze column 63 is installed on the limit block 61, and a squeeze frame 64 for driving the squeeze column 63 to move is installed on the rack 52. In the present application, the limit block 61 is slidably connected to the support frame 1, the limit block 61 and the support frame 1 are connected by a spring, a limit hole 62 for the limit block 61 to be inserted is provided on the lower die 2, a squeeze column 63 is installed on the limit block 61, and a squeeze frame 64 for driving the squeeze column 63 to move is installed on the rack 52. When the L frame 51 drives the rack 52 to move upward, the rack 52 drives the squeeze frame 64 to squeeze the squeeze column 63, so that the squeeze column 63 drives the limit block 61 to move outward, and the limit block 61 slides out of the limit hole 62, and then the rack 52 passes The lower die 2 is driven to flip over by meshing with the gear 53. Then, when the L frame 51 drives the rack 52 to move downward, the rack 52 drives the lower die 2 to rotate counterclockwise. When the lower die 2 rotates to a horizontal position, the extrusion frame 64 will no longer squeeze the extrusion column 63. The spring pushes the limit block 61 to insert into the limit hole 62 to prevent the lower die 2 from flipping over. Then, the upper die 4 continues to move downward to cooperate with the lower die 2 for stamping, and only one power source is needed to lock or release the lower die 2, which reduces the production cost, improves the qualified rate of workpieces, and reduces labor intensity.

The present application installs a detection module 10 on the positioning frame 8, and the detection module 10 includes an EMS system detection device. Through the scanning device of the detection module 10, during the flipping process of the lower mold 2, the mold surface of the lower mold 2 is scanned, and then the wear degree of the lower mold 2 is transmitted to the EMS system, and the wear degree of the lower mold 2 is analyzed. When the wear degree of the lower mold 2 exceeds 30%, the EMS system will remind the operator to replace the lower mold 2. The number of flipping of the lower mold 2 can also be monitored through the detection module 10, and then the number of flipping of the lower mold 2 is recorded through the EMS system, which is convenient for the operator to maintain the lower mold 2, thereby extending the service life and facilitating unified management of personnel.
