Description

Technical Field

[0001] The utility model relates to a steering wheel skeleton mucosa removal device, in particular to the structure of the steering wheel skeleton mucosa removal device. Background Art

[0002] The steering wheel is an important part of the car's control system. The steering wheel frame is connected to the car's steering shaft through a steel bushing. The steering wheel frame is made of magnesium alloy through a die-casting mold. The die-casting mold usually includes a movable mold, a fixed mold, a guide mechanism, a pouring system and an ejection mechanism.

[0003] During the die-casting of the steering wheel frame, the movable mold is guided by the guide mechanism and combined with the fixed mold to form a cavity. The steel sleeve is placed in the cavity, and the pouring system hydraulically presses the metal in the pressure chamber into the cavity to die-cast the steering wheel frame in the cavity. After the steering wheel frame is die-cast, the steel sleeve is embedded in the steering wheel frame as an insert, and the ejection mechanism demolds the steering wheel frame from the cavity.

[0004] During the die-casting process of the steering wheel frame, due to the adjustment of the die-casting process parameters, such as the pouring pressure, temperature and speed exceeding the process range, and the high temperature of the cooling water of the die-casting mold, the die-cast steering wheel frame will be sticky as a whole on the fixed mold side. After sticking, the steering wheel frame is difficult to demold.

[0005] The existing method generally uses a lever to pry the steering wheel frame out of the mold cavity, or uses a waste ejector to knock and vibrate it to remove it. When the clamping force between the steering wheel frame and the fixed mold core inside the fixed mold is large, the machine needs to be stopped and the mold disassembled before removal. This will damage the die-casting mold, and the removal efficiency is low, time-consuming and labor-intensive, affecting production efficiency.

[0006] The utility model aims to solve the problem that in the die-casting process of the steering wheel skeleton, when the steering wheel skeleton after the mucous film is taken out, the die-casting mold is easily damaged and the removal efficiency is low. Utility Model Content

[0007] In order to solve the above problems, the utility model provides a steering wheel skeleton mucosa removal device, including a slide rod 1, a sliding member 2 and a connecting member 3. The slide rod 1 is a straight rod with a stop block 11 provided at the rear end. The slide member 2 is sleeved on the slide rod 1 and can slide along the slide rod 1. The connecting member 3 is provided at the front end of the slide rod 1 and is detachably connected to the slide rod 1. The connecting member 3 is used to be fixedly connected to the shaft sleeve 41 on the steering wheel skeleton 4.

[0008] When using the present invention, the connector 3 is fixedly connected to the shaft sleeve 41 on the steering wheel frame 4 of the adhesive film, and the slider 2 is held and slid back and forth along the slide rod 1. The slider 2 continuously impacts the stopper 11 at the rear end of the slide rod 1, causing the steering wheel frame 4 of the adhesive film to be continuously vibrated. The clamping force between the steering wheel frame 4 and the fixed mold is released, and the mold is smoothly removed. The present invention can quickly remove the steering wheel frame 4 after adhesive film is formed without damaging the die-casting mold.

[0009] Preferably, a screw rod 12 is provided at the front end of the sliding rod 1, and the connecting member 3 includes a connecting rod 31 and a nut 32. The connecting rod 31 is a straight rod, one end of which is fixedly connected to the nut 32, and the other end is used to be fixedly connected to the sleeve 41 on the steering wheel frame 4. The nut 32 is connected to the screw rod 12 through threads.

[0010] By setting a screw 12 at the front end of the slide rod 1 and setting a nut 32 on the connecting part 3, the connecting rod 31 and the slide rod 1 are detachably connected through the cooperation of the nut 32 and the screw 12. When the steering wheel skeleton 4 of the mucosa is demolded, the connection between the connecting rod 31 and the slide rod 1 can be made firm. After the steering wheel skeleton 4 of the mucosa is demolded, the disassembly and assembly of the connecting rod 31 and the slide rod 1 can be facilitated.

[0011] Preferably, a limit block 13 is provided at the front end of the slide bar 1. The limit block 13 is provided at the front end of the slide bar 1 to prevent the sliding block from falling from the front end of the slide bar 1.

[0012] Preferably, the sliding member 2 includes a sliding cylinder 21 and a collision block 22. The sliding cylinder 21 is sleeved on the sliding rod 1 and can slide along the sliding rod 1. The collision block 22 is fixedly mounted at the rear end of the sliding cylinder 21. The collision block 22 at the rear end of the sliding cylinder 21 can enhance the impact force of the sliding member 2 on the stopper 11. The continuous impact of the sliding member on the stopper 11 by the sliding member causes the steering wheel frame 4 to be continuously vibrated, and the clamping force is released, allowing for smooth demolding.

[0013] Preferably, the sliding member 2 further includes a protective block 23, which is fixedly mounted at the front end of the sliding cylinder 21. The protective block 23 is provided at the front end of the sliding cylinder 21 to protect the operator's hands from colliding with the stopper 11 when the sliding member 2 is operated, thereby preventing the operator's hands from being injured by colliding with the stopper 13.

[0014] Preferably, the slider 2 is provided with a shock-absorbing cushion 24, which covers the outer periphery of the sliding cylinder 21 and the inner side surfaces of the collision block 22 and the protection block 23. By providing the shock-absorbing cushion 24 on the slider 2, when the slider 2 collides with the stopper 11, the slider 2 can be damped, thereby preventing the operator's hand from being injured.

[0015] Preferably, the sliding member 2 is an integrally formed structure, which can improve the firmness of the sliding member 2.
