Description

Technical Field

[0001] This utility model relates to the field of automotive steering knuckle forging die technology, specifically a forging die for automotive steering knuckle blanks. Background Technology

[0002] The steering knuckle is a key component of the car's steering system. It has a complex structure and typically includes fork lugs, discs, and rods.

[0003] In the prior art, publication number "CN115502319B" discloses a forging die for an automotive steering knuckle blank, including an upper die and a lower die. The upper die has an upper cavity corresponding to the fork lug of the steering knuckle blank, and the lower die has a lower cavity corresponding to the disc and rod portions of the steering knuckle blank. The lower cavity includes a through hole for accommodating the rod portion, the axis of which forms an angle α with the vertical direction. The lower die has an ejector guide hole, which includes a vertical guide hole and an inclined guide hole. The two ends of the inclined guide hole are connected to the vertical guide hole and the through hole, respectively. An inclined ejector mechanism is provided in the ejector guide hole. The inclined ejector mechanism includes a vertical ejector rod, a rolling steel ball, and an inclined ejector rod. The angle between the axis of the inclined ejector rod and the axis of the vertical ejector rod is also α. Several rolling steel balls are provided, all located between the vertical ejector rod and the inclined ejector rod. The forging die of this invention can directly forge the inner inclination angle of the steering knuckle and smoothly eject and demold, reducing the finished product machining allowance and reducing raw materials.

[0004] However, existing technologies still have significant shortcomings, such as: In the aforementioned device and existing technology, when forging is completed, demolding can be performed by adjusting the inclination angle of the steering knuckle. However, since the steering knuckle temperature is high at this time, it is difficult to demold without external force. As a result, when the steering knuckle forging is completed, the steering knuckle will be tightly engaged with the mold. If a demolding structure is not used, the forging efficiency of the steering knuckle will be affected. Utility Model Content

[0005] The purpose of this invention is to provide a forging die for an automobile steering knuckle blank, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forging die for an automotive steering knuckle blank, comprising a main die base, an assembly base, and a forging base. The forging base is eccentrically mounted through the surface of the main die base. A die arm one and a die arm two are mounted on the surface of the main die base. The main die base, the die arm one, and the die arm two together form an upper cavity corresponding to the fork lug of the steering knuckle blank. A lower cavity is provided at the bottom of the forging base, which corresponds to the disc and rod portions of the steering knuckle blank. A demolding assembly is provided on one side of the top of the main die base. The demolding assembly is used to effectively remove the forged steering knuckle blank from the die.

[0007] Preferably, the demolding assembly includes a demolding seat, which is installed on the top of the main mold base and is opposite to the mold arm. The surface of the main mold base is provided with an interference groove, and a demolding hole is provided in the central area of ​​the interference groove.

[0008] Preferably, the tilt angle between the mold arm and the main mold base is set to 15°.

[0009] Preferably, a forming ring is installed on the top of the mold arm, and the forming ring has a through hole through which the rod can pass.

Please see Figure 1-5 This utility model provides a technical solution: Example 1: A forging die for an automotive steering knuckle blank includes a main die base 1, an assembly base 4, and a forging base 6. The forging base 6 is eccentrically mounted through the surface of the main die base 1. A die arm 1 2 and a die arm 2 3 are mounted on the surface of the main die base 1. The main die base 1, die arm 1 2, and die arm 2 3 together form an upper cavity corresponding to the fork lug of the steering knuckle blank. A lower cavity 61 is provided at the bottom of the forging base 6. The lower cavity 61 corresponds to the disc and rod portions of the steering knuckle blank. A demolding assembly is provided on one side of the top of the main die base 1. The demolding assembly is used to effectively remove the forged steering knuckle blank from the die.

[0020] The demolding assembly includes a demolding seat 5, which is installed on the top of the main mold base 1. The demolding seat 5 is opposite to the mold arm 3. An interference groove 52 is provided on the surface of the main mold base 1, and a demolding hole 51 is provided in the central area of ​​the interference groove 52.

[0021] The tilt angle between mold arm 2 and main mold base 1 is set to 15°.

[0022] A forming ring 21 is installed on the top of the mold arm 2, and the forming ring 21 has a through hole through which the rod can pass.

[0023] The tilt angle between mold arm 2 3 and main mold base 1 is set to 35°.

[0024] A forming ring 31 is installed on the top of the mold arm 2 3. An extension arm 32 is installed on one side of the forming ring 2 31. A forming ring 33 is installed on one side of the extension arm 32. The forming ring 2 31 and the forming ring 33 also have through holes through which the rod can pass.

[0025] An assembly base 4 is installed on the side of the main mold base 1 away from the mold arm 2, and the surface of the assembly base 4 is provided with assembly holes.

[0027] Working principle: The operator can position and clamp the mold assembly through the assembly base 4 and its assembly holes. After clamping, the material to be forged is placed in the mold for forging the inner inclination angle of the steering knuckle surface. During the processing, the inclination angle between the mold arm 1 2 and the mold arm 2 3 and the main mold base 1 is quantitatively set, which can effectively form and forge the bottom inclination angle of the steering knuckle blank, thereby improving the forming effect of the inner inclination angle of the steering knuckle blank. After the bottom inclination angle of the steering knuckle blank is forged, the external demolding pry bar can be inserted into the demolding hole 51 on the surface of the demolding seat 5. As the demolding pry bar is continuously inserted, one end of the demolding pry bar will press against the gap area between the bottom of the steering knuckle blank and the top of the main mold seat 1. As the demolding pry bar continues to go deeper, the steering knuckle blank will loosen. If the steering knuckle blank is still tight, the demolding pry bar can be pried to make one end of the demolding pry bar lift the bottom of the steering knuckle blank. At this time, the interference groove 52 opens to ensure effective demolding of the steering knuckle blank.
