Description

Technical Field

[0001] This utility model relates to the field of forging die technology, and more specifically, to a ball cage flange forging die. Background Technology

[0002] The ball joint is a key component of an automotive drive system, its core function being to stably transmit torque even when the wheels are turning. The flange, as a crucial structural component connecting the ball joint to the wheel hub bearing or drive shaft, is typically manufactured using a forging process. This forging process requires a forging die. For example, patent application number 202222934320.7 proposes a forging die for an automotive steering arm, comprising a forging die body and an injection mold, the injection mold being slidably connected to the top of the forging die body. By incorporating a limiting component, the injection mold is secured and its use is ensured. When material needs to be removed, a material removal mechanism can lift the injection mold and remove it, thus assisting in manual material handling.

[0003] The above-mentioned structure for ejecting the formed workpiece requires manual operation to turn the screws to eject the workpiece. Both screws need to be turned at the same time, which is quite troublesome. When ejecting heavy workpieces, turning the screws requires a lot of force. Therefore, we have made an improvement and proposed a ball cage flange forging die. Utility Model Content

[0004] The main purpose of this utility model is to provide a ball cage flange forging die, which can effectively solve the problem that the structure used to eject the formed workpiece requires manual operation to turn the screw to eject the workpiece, and requires turning two screws at the same time, which is more troublesome. When it is necessary to eject a heavy workpiece, turning the screw requires a lot of force.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ball cage flange forging die includes a base, a lower die mounted on the upper surface of the base, a support frame mounted on the upper surface of the base, a pusher cylinder mounted on the top of the support frame, an upper die mounted on the output end of the pusher cylinder, ejection mechanisms provided on both sides of the lower die and the upper die, and a forming groove provided inside the lower die.

[0007] Preferably, the ejection mechanism includes a first side plate, a second side plate, and a third side plate. The first side plate is mounted on the two end surfaces of the upper mold, and the second and third side plates are respectively mounted on the upper and lower sides of the two end surfaces of the lower mold. A connecting rod is mounted on the lower surface of each first side plate.

[0008] Preferably, a movable frame is slidably installed inside each of the third side plates, and a top rod is installed on one side of the bottom of each movable frame.

[0009] Preferably, the top of each ejector pin is slidably disposed inside the lower mold, and a circular top block is installed at one end of each ejector pin. An avoidance groove that mates with the circular top block is provided on the bottom inner wall of the forming groove.

[0010] Preferably, each of the movable frames is rotatably mounted on its top with a rotating column, each rotating column is mounted on its top with a positioning block, and each rotating column has anti-slip protrusions on its outer surface.

[0011] Preferably, a positioning plate is installed at the bottom of the connecting rod, and a positioning groove corresponding to the position of the positioning plate is opened through the surface of the second side plate.

[0012] Preferably, each of the positioning plates has a through groove on its surface.

[0013] Preferably, each of the positioning plates has a groove on its upper surface that can cooperate with the positioning block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By controlling the rotation of the rotating column, the positioning block is positioned inside the groove. During the upward movement of the upper mold, the positioning plate pulls the moving frame to move together, which in turn causes the ejector rod to move the circular ejector block upward. The circular ejector block can be used to eject the formed workpiece. During the separation of the upper and lower molds, the workpiece can be ejected from the forming groove without the need for manual operation, which can effectively improve processing efficiency.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1 , Figure 2 , Figure 4 As shown, a ball cage flange forging die includes a base 1, a lower die 2 mounted on the upper surface of the base 1, a support frame 3 mounted on the upper surface of the base 1, a push cylinder 4 mounted on the top of the support frame 3, an upper die 5 mounted on the output end of the push cylinder 4, an ejection mechanism 6 provided on both sides of the lower die 2 and the upper die 5, and a forming groove 7 provided inside the lower die 2.

[0026] like Figures 3 to 7As shown, the ejection mechanism 6 includes a first side plate 601, a second side plate 602, and a third side plate 603. The first side plate 601 is mounted on both ends of the upper mold 5. The second side plate 602 and the third side plate 603 are respectively mounted on the upper and lower sides of both ends of the lower mold 2. A connecting rod 604 is mounted on the lower surface of each first side plate 601. A movable frame 606 is slidably mounted inside each third side plate 603. A push rod 607 is mounted on one side of the bottom of each movable frame 606. The top of each push rod 607 is slidably disposed inside the lower mold 2. A circular push block 608 is mounted on one end of each push rod 607. The bottom inner wall of 7 is provided with a clearance groove 701 that mates with the circular top block 608. Each movable frame 606 has a rotating column 609 rotatably mounted on its top. Each rotating column 609 has a positioning block 610 mounted on its top. Each rotating column 609 has an anti-slip protrusion 611 on its outer surface. The bottom of the connecting rod 604 is provided with a positioning plate 605. The surface of the second side plate 602 is provided with a positioning groove 6021 that corresponds to the position of the positioning plate 605. Each positioning plate 605 has a through groove 612 on its surface. The upper surface of each positioning plate 605 has a retaining groove 613 that mates with the positioning block 610.

[0027] When the positioning block 610 corresponds to the through groove 612, the upper mold 5 will not move the lower movable frame 606 during its movement. When the positioning block 610 is inside the retaining groove 613, the upper mold 5 can move the movable frame 606 together with it, so that the circular top block 608 can eject the workpiece. The workpiece can be ejected without manual operation, saving time and effort and making the operation more convenient. The positioning groove 6021 can play a positioning role during the downward movement of the positioning plate 605, which is convenient for cooperation. The rotating column 609 has anti-slip protrusions 611 on its surface, which is convenient for controlling the rotation.

[0028] The working principle of a ball cage flange forging die:

[0029] By pushing the electric cylinder 4 to move the upper mold 5, it closes with the lower mold 2, and the material is placed inside the forming groove 7. Through the cooperation of the upper mold 5 and the lower mold 2, the forging of the ball cage flange is completed. During the downward movement of the upper mold 5, the positioning plate 605 passes through the positioning groove 6021. The initial position of the positioning block 610 corresponds to the through groove 612. When the positioning plate 605 moves downward, the positioning block 610 will completely pass through the through groove 612. After the workpiece is forged, before the upper mold 5 and the lower mold 2 are separated, the rotating column 609 is rotated so that the positioning block 610 is inside the retaining groove 613. Then, by pushing the upper mold 5 at both ends of the electric cylinder 4 to move upward, the retaining groove 613 will block the positioning block 610. During the upward movement, the positioning plate 605 will pull the moving frame 606 to move together, which will cause the ejector rod 607 to drive the circular ejector block 608 to move upward. The circular ejector block 608 can be used to eject the formed workpiece. During the separation of the upper mold 5 and the lower mold 2, the workpiece can be ejected from the inside of the forming groove 7 without manual operation, which can effectively improve the processing efficiency. The circular ejector blocks 608 are symmetrically arranged, and the workpiece is lifted from both sides at the same time, which is more conducive to ejecting the workpiece.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
