DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0026] As Figures 1-5 shown, the forging die ejection device provided in the embodiment includes a fixed seat 1, the inner wall of the fixed seat 1 is slidably connected with symmetrically distributed square blocks 7, the outer wall of the square blocks 7 is fixedly connected with inclined blocks 10, the outer wall of the square blocks 7 and the outer wall of the fixed seat 1 are both provided with detachable assemblies, the top wall of the fixed seat 1 is provided with an upper forging die part 2, and the forging die operation is performed through the upper forging die part 2, and the forging die ejection device further includes:

[0027] The anti-displacement assembly includes a rotating rod 11 rotatably connected to the inner wall of the fixed seat 1, the outer wall of the rotating rod 11 is fixedly connected with screw rods 12 symmetrically distributed about the fixed seat 1, the outer wall of the screw rods 12 is threadedly connected with sliding blocks 14, and the sliding blocks 14 are slidably connected with the fixed seat 1, the top wall of the sliding blocks 14 is fixedly connected with symmetrically distributed baffles 16, and the outer wall of the screw rods 12 is fixedly connected with knobs 13. When it is necessary to prevent the die from being displaced during the forging process, the knob 13 is rotated, the knob 13 drives the screw rod 12 to rotate, the screw rod 12 rotates to make the sliding block 14 slide along the guide rod 19 in the fixed seat 1, and the baffle 16 on the sliding block 14 will be close to the die, thereby limiting and fixing the die and preventing the die from being displaced during the forging process.

[0028] As Figures 3-4As shown, in a preferred embodiment, based on the above method, the detachable component further includes a connecting block 3 slidably connected to the outer wall of the square block 7 and the fixed base 1. Evenly distributed telescopic springs 8 are fixedly connected between adjacent connecting blocks 3. A positioning groove 18 is provided on the outer wall of the outer connecting block 3. A limiting spring 17 is fixedly connected to the inner wall of the positioning groove 18. A limiting block 9 is fixedly connected to the end of the limiting spring 17 away from the positioning groove 18, and the limiting block 9 is slidably connected to the fixed base 1 and the connecting block 3. When the telescopic spring 8 needs to be disassembled, it is only necessary to push the outer connecting block 3 inward, thereby moving the limiting block 9 and the limiting spring 17, so that the limiting block 9 is dislodged from the fixed base 1. At this time, the connecting block 3 can be directly removed for replacement. During forging, the elastic force of the limiting block 9 and the limiting spring 17 prevents the connecting block 3 from detaching from the fixed base 1 and the square block 7, keeping the position of the connecting block 3 stable.

[0029] like Figure 2 As shown, in a preferred embodiment, based on the above method, a lifting plate 4 is slidably connected to the inner wall of the fixed base 1, and uniformly distributed ejector pins 5 are fixedly connected to the top wall of the lifting plate 4. A push rod 6 is fixedly connected to the end of the lifting plate 4 away from the ejector pins 5, and both the push rod 6 and the ejector pins 5 are slidably connected to the fixed base 1. When the mold fails to eject, the lifting plate 4 is pushed upward by the push rod 6, and the lifting plate 4 drives the ejector pins 5 to move upward, thus ejecting the forged workpiece from the mold.

[0030] like Figure 3 As shown, in a preferred embodiment, based on the above method, a telescopic rod 15 is fixedly connected between adjacent connecting blocks 3, and the telescopic rod 15 strengthens the connection between the connecting blocks 3.

[0031] like Figure 5 As shown, in a preferred embodiment, based on the above method, the inner wall of the fixed base 1 is further provided with symmetrically distributed guide rods 19, and the guide rods 19 are slidably connected to the slider 14, and the guide rods 19 provide stable sliding support force for the slider 14.

[0032] Specifically, the forging die ejecting device in use: the upper forging die part 2 moves downward for forging operation, in the forging process, the inclined block 10 is moved outward by the extrusion force of the upper forging die part 2 and the die, and then the extension spring 8 is compressed, at this time, the extension spring 8 is elastically stored; after the forging is completed, the extension spring 8 releases the elastic storage, and then pushes the square block 7 and the inclined block 10 to the center, and then pushes the formed die out, when the die fails to push out, the push rod 6 pushes the lifting plate 4 upward, the lifting plate 4 drives the ejector pin 5 to move upward, and the forged workpiece is ejected from the die; when the die needs to be prevented from moving during forging, the knob 13 is rotated, the knob 13 drives the screw rod 12 to rotate, the screw rod 12 rotates to make the sliding block 14 slide in the fixed seat 1 along the guide rod 19, the baffle 16 on the sliding block 14 is close to the die, thereby limiting and fixing the die, preventing the die from moving during forging; when the extension spring 8 needs to be disassembled, only the connecting block 3 on the outside needs to be pushed inward, thereby driving the limiting block 9 and the limiting spring 17 to move, so that the limiting block 9 is separated from the fixed seat 1, at this time, the connecting block 3 can be directly taken out for replacement; during forging, the limiting block 9 cooperates with the elastic force of the limiting spring 17 to prevent the connecting block 3 from separating from the fixed seat 1 and the square block 7, and the position of the connecting block 3 is stable.

[0033] The above examples are only used to illustrate the present application and are not limited to the technical solutions described in the present application. Although the present application has been described in detail with reference to the above embodiments, the present application is not limited to the above specific embodiments, and any modification or equivalent replacement of the present application is allowed. Any technical solution and improvement within the spirit and scope of the application is covered by the claims of the present application.
