Quick demolding anti-deformation ejection device for knuckle mold

Abstract

This utility model relates to the field of steering knuckle mold technology, specifically a quick demolding and anti-deformation ejection device for steering knuckle molds. It includes a demolding mechanism, which comprises a second outer shell. A closing plate is provided on the inner side of the second outer shell, and the inner side of the second outer shell is fixedly connected to the top side of the closing plate. A mold cavity is provided at one end of the closing plate. This quick demolding and anti-deformation ejection device for steering knuckle molds rotates a lead screw, causing the toothed plate connected to the lead screw to move, thus rotating the gear. When the connecting rod rotates, the tilt angle of the movable arm begins to change. During this process, the first outer shell gradually separates from the second outer shell, and the closing plate and mold cavity move along with their respective connected components. During the movement of the mold cavity, the inner plate remains stationary, allowing the contents inside to be ejected from the mold cavity under resistance. This gradual external force avoids product deformation caused by excessive ejection force.

Description

[0002] Device. Background Technology

[0003] The steering knuckle is a core component of the car chassis system. Shaped like a ram's horn, it connects the wheels, suspension, and steering system.

[0004] Key joint. It mainly consists of upper and lower forked lugs, journals, and other structural components, and is usually forged from medium carbon steel or alloy steel and heat-treated.

[0012] It allows metal materials to flow uniformly and fully fill the mold cavity under high temperature and high pressure, forming a steering knuckle part with a dense internal structure;

[0013] However, after the raw material is shaped, traditional molds lack an ejection structure inside the cavity, forcing the use of tools as a means of ejection.

[0014] When removing a shaped object using tools, improper operation may result in the tools coming into direct contact with the product surface.

A gear 16 is provided on the outside of the connecting rod 115. The outside of the connecting rod 115 is fixedly connected to the center of the gear 16. A toothed plate 17 is provided on one side of the gear 16. One side of the gear 16 is slidably engaged with the top side of the toothed plate 17. A lead screw 18 is provided on the inner wall of the toothed plate 17. The inner wall of the toothed plate 17 is threadedly rotatably connected to the outside of the lead screw 18. One end of the lead screw 18 is rotatably connected to the inner wall of the base plate 113. The inner wall of the base plate 113 is slidably connected to the bottom side of the toothed plate 17. A movable arm 14 is provided on one side of the connecting rod 115. One side of the connecting rod 115 is connected to the movable arm 14.

The inside of the mold cavity 19 is fixedly connected to the bottom end of the receiving tube 114. The outer side of the receiving tube 114 is fixedly connected to the inner wall of the outer shell 11.

[0066] When using this type of steering knuckle mold with a quick demolding and anti-deformation ejection device, firstly, through the design of the outer shell - 11

[0067] The outer shell 11 and the second outer shell 12 are connected by a mold cavity 19 on the inner side of the outer shell 11. One end of the mold cavity 19 is connected to a closing plate 110, and the top side of the closing plate 110 is connected to the second outer shell 12. At this time, the raw material is poured into the mold cavity 19 through the receiving pipe 114. As time goes by, when the raw material in the mold cavity 19 has been shaped, the object needs to be removed from the mold cavity 19. Therefore, an inner plate 111 is provided on the inner wall of the mold cavity 19. The two are connected in a fitting manner, and one end of the inner plate 111 is connected to a folding rod 112. The folding rod 112 is connected to the bottom plate 113 to provide support for the inner plate 111. Since a side plate 15 is provided on one side of both the first outer shell 11 and the second outer shell 12, and the inside of the side plate 15 is designed with a movable arm 14, the movable arm 14 is inclined when not driven. Then, by rotating the lead screw 18, the lead screw 18 is able to move. The connected toothed plate 17 moves, meshing with the gear 16 during this movement, causing the gear 16 to rotate. The gear 16 and connecting rod 115 are integrated, and the movable arm 14 is designed on the connecting rod 115. Therefore, as the connecting rod 115 rotates, the tilt angle of the movable arm 14 changes, gradually evolving from an inclined state to a lateral state. During this process, outer shell 11 gradually separates from outer shell 12, causing the closing plate 110 and mold cavity 19 to move along with their respective connected components. During the movement of the mold cavity 19, the inner plate 111 remains stationary. This allows the contents of the mold cavity 19 to be ejected from the mold cavity 19 under resistance. This relative motion design allows the molded steering knuckle to naturally eject without direct external impact, relying on the displacement difference between the mold cavity 19 and the inner plate 111. This ensures efficient demolding while the gradual external force effectively avoids product deformation caused by excessive ejection force.

[0068] Example 2: Please refer to Figures 3-4. The receiving mechanism 2 includes a platform 21. A support column 22 is provided on the bottom side of the platform 21. The bottom side of the platform 21 is fixedly connected to the top of the support column 22. The outer side of the support column 22 is connected through to the inner walls of the outer shell 11 and the outer shell 22 respectively. The bottom end of the support column 22 is fixedly connected to the top side of the base plate 113.

[0069] A support column 22 is designed at the top center of the base plate 113, and a platform 21 is designed at the top of the support column 22. The platform 21 is located below the mold cavity 19. When the mold cavity 19 moves, the object will naturally fall onto the platform 21 when it is pushed by the movement of the mold cavity 19. The platform 21 will receive the object and prevent it from falling directly onto the base plate 113 due to gravity, thus ensuring the integrity of the object when it comes out.

[0070] Referring to Figures 1-5: By rotating the lead screw 18, the toothed plate 17 connected to the lead screw 18 moves.

[0071] During the movement, it will mesh with gear 16, causing gear 16 to rotate. Gear 16 and connecting rod 115 are integrated, and movable arm 14 is designed on connecting rod 115. Therefore, when connecting rod 115 rotates, the tilt angle of movable arm 14 begins to change, gradually evolving from a tilted state to a lateral state. During this process, outer shell 11 will gradually separate from outer shell 12, and then closing plate 110 and mold cavity 19 will move along with their respective connected components. During the movement of mold cavity 19, inner plate 111 will remain stationary in its original position. This design allows the object inside the mold cavity 19 to detach from the mold cavity 19 when subjected to resistance. This relative motion design enables the molded steering knuckle to detach naturally without direct external impact, relying on the displacement difference between the mold cavity 19 and the inner plate 111. Secondly, a support column 22 is designed at the top middle of the bottom plate 113, and a platform 21 is designed at the top of the support column 22. The platform 21 is located below the mold cavity 19. When the mold cavity 19 moves, the object inside the mold cavity 19 will naturally fall onto the platform 21 when it is pushed, and the platform 21 will receive it, avoiding it from falling directly onto the bottom plate 113 and falling due to gravity.
