[0016] 1. The utility model sets a movable die, and the bottom end of the movable die is fixedly connected to the connecting plate. After forging is completed, the pressure piston drives the top die to move upward. Since the bottom surface of the top die is fixedly connected to the limiting column, the top die will drive the limiting column to move upward while moving. When the blocking plate at the bottom end of the limiting column contacts the bottom surface of the connecting plate, the connecting plate will be driven to move upward, so that the relative position between the movable die and the bottom die is changed, thereby ejecting the iron teeth inside the bottom die. Since the top surface of the movable die is embedded with the bottom surface of the iron teeth, this method can make the bottom surface of the iron teeth receive a relatively uniform vertical upward force during the process of ejecting the iron teeth, and prevent the iron teeth from being stuck with the bottom die while facilitating demoulding.

Since the limit column is installed at the four corners of the bottom surface of the top mold, the limit column can limit the top mold so that the top mold can only move upward in the vertical direction, thereby avoiding changes in the relative position between the top mold and the bottom mold.

[0027] The top surface of the support block 11 and the bottom end of the connecting rod 16 are in the same plane, the center of the support block 11 and the center of the bottom plate 1 are in the same straight line, and the limiting hole 13 is symmetrically arranged on the top surface of the connecting frame 12 front to back and left to right with the center of the connecting frame 12 as the reference, and the limiting hole 13 vertically penetrates the connecting frame 12.

[0028] The center of the movable mold 14 and the center of the connecting frame 12 are in the same straight line. The movable mold 14 vertically penetrates the connecting frame 12, and a sliding connection is formed between the movable mold 14 and the connecting frame 12.

[0029] The top of the connecting rod 16 is fixedly connected to the bottom surface of the connecting frame 12. The connecting rod 16 is symmetrically installed at the four corners of the connecting plate 15 with the center of the connecting plate 15 as the reference, and a sliding connection is formed between the connecting plate 15 and the connecting rod 16.

[0030] An opening structure vertically penetrating the bottom mold 18 is disposed at the center of the bottom mold 18 , and the opening structure of the bottom mold 18 is engaged with the movable mold 14 .

[0031] Specifically, the base plate 1 can support the support block 11 and the connecting frame 12, the support block 11 can support the connecting plate 15, the connecting frame 12 can support the bottom mold 18, the limiting hole 13 can allow the limiting column 24 to pass through the connecting frame 12, the movable mold 14 can facilitate the ejection of the iron teeth from the inside of the bottom mold 18, the connecting plate 15 can support the movable mold 14, the connecting rod 16 can limit the movement direction of the connecting plate 15, the limiting plate 17 can limit the displacement distance of the connecting plate 15, and the bottom mold 18 can limit the shape of the iron teeth.

[0032] A limiting frame 2 is fixedly installed above the connecting frame 12, a mounting hole 21 is provided above the limiting frame 2, a pressure piston 22 is inserted into the mounting hole 21, a top mold 23 is fixedly installed below the pressure piston 22, a limiting column 24 is fixedly installed below the top mold 23, and a blocking disk 25 is fixedly installed at the lower end of the limiting column 24.

[0033] The mounting holes 21 are symmetrically arranged at the front and rear ends of the top surface of the limiting frame 2 with the center of the limiting frame 2 as a reference, and the mounting holes 21 vertically penetrate the limiting frame 2, and the pressure piston 22 and the limiting frame 2 are fixedly connected.

[0034] The limiting column 24 is symmetrically installed at the front and rear ends of the left and right sides of the bottom surface of the top mold 23 with the center of the top mold 23 as the reference. The installation position of the limiting column 24 matches the limiting hole 13. The limiting column 24 passes through the connecting frame 12 and the connecting plate 15, and a sliding connection is formed between the limiting column 24 and the connecting frame 12 and the connecting plate 15.

[0035] Specifically, the limit frame 2 can fix the direction and position of the pressure piston 22 through the mounting hole 21, the pressure piston 22 can drive the top mold 23 to move downward, the top mold 23 can drive the limit column 24 to move, the limit column 24 can limit the vertical position between the top mold 23 and the connecting frame 12, and drive the connecting plate 15 to move through the blocking plate 25.

[0036] When in use, the limiting column 24 vertically penetrates the connecting frame 12 and the connecting plate 15. Since the top surface of the connecting plate 15 is fixedly connected to the movable mold 14, and the movable mold 14 penetrates the connecting frame 12, the relative position between the connecting plate 15 and the connecting frame 12 can only be changed in the vertical axial direction. The direction of the limiting column 24 will be limited by the connecting frame 12 and the connecting plate 15, so that the limiting column 24 remains in a vertical state.

The top mold 23 is driven downward by the pressure piston 22, so that the bottom surface of the top mold 23 contacts the top surface of the bottom mold 18. Since the bottom end of the movable mold 14 is fixedly connected to the connecting plate 15, when the top mold 23 contacts the bottom mold 18, the movable mold 14 and the connecting plate 15 It will move to the lower end of the connecting rod 16 under the action of gravity, and the bottom surface of the connecting plate 15 will contact the support block 11. The support block 11 will support the movable die 14 through the connecting plate 15 during the forging process. After the forging is completed, the pressure piston 22 drives the top die 23 to move upward. Since the bottom surface of the top die 23 is fixedly connected to the limiting column 24, the movement of the top die 23 will drive the limiting column 24 to move upward. When the blocking plate 25 at the bottom end of the limiting column 24 contacts the bottom surface of the connecting plate 15, it will drive the connecting plate 15 to move upward, so that the relative position between the movable die 14 and the bottom die 18 changes, thereby ejecting the iron teeth inside the bottom die 18. Since the top surface of the movable die 14 is embedded with the bottom surface of the iron teeth, this method can make the bottom surface of the iron teeth receive a relatively uniform vertical upward force during the ejection process, while facilitating demoulding and avoiding the iron teeth and the bottom die 18 from getting stuck.
