[0002] Automobile engine shock absorbers are devices designed specifically to reduce the transmission of engine vibrations to the vehicle body. Their installation location and specific functions are crucial to the handling and comfort of the vehicle. When the engine vibrates, the shock absorbers will deform to absorb and disperse the vibration energy, reducing the amplitude transmitted to the chassis and body.

[0003] When producing automobile engine shock absorbers, the raw materials are usually poured into a mold and the raw materials are pressed into shape by the mold. After pressing and forming, the shock absorber will remain inside the mold. If the shock absorber is tightly adsorbed to the inside of the mold, it is inconvenient to remove the shock absorber from the mold, resulting in reduced convenience when using the pressing and forming device. Utility Model Content

[0004] The utility model aims to solve the problem that if the shock-absorbing pad is closely adsorbed to the inside of the mold, it is inconvenient to take the shock-absorbing pad out of the mold, resulting in reduced convenience when using the pressing molding device, and proposes a pressing molding device for automobile engine sound insulation and shock-absorbing pads.

[0006] The effect achieved by the above components is: when using a pressing molding device to produce sound insulation and shock absorbing pads, the raw materials of the shock absorbing pads are poured into the mold groove, and then the shaft rod and the mold cover are driven to rotate by operating the motor, so that the mold cover is pressed on the top of the machine body and fits with the top of the machine body, and the convex mold on the surface of the mold cover is pressed into the mold groove, and the machine body is heated by the electric heating module inside the machine body to form the raw materials. After a period of time, the motor is operated to drive the shaft rod and the mold cover to rotate to open the mold cover and take out the shock absorbing pad in the mold groove.

[0007] Preferably, the ejection device includes a half gear, one side of the half gear is fixedly connected to one end of the shaft rod, a T-shaped groove is provided on one side of the machine body close to the half gear, a T-shaped block is slidably connected to the inner wall of the T-shaped groove, a connecting rod is fixedly connected to one side of the T-shaped block, one end of the connecting rod is rotatably connected to a round rod, a round block is fixedly connected to the inner wall of the mold groove, the round rod moves inside the round block, a slide groove is provided on one side of the top of the T-shaped block, a gear rod is slidably connected to the inner wall of the slide groove, one side of the gear rod is meshed with one side of the half gear, two springs are provided on one side of the gear rod, and the two ends of the two springs are respectively fixedly connected to one side of the gear rod and one side of the inner wall of the slide groove.

After the half gear moves away from the gear rod, the spring will return to its original state and push the gear rod to move outward to return to its original position. When the mold cover is rotated upward to open, one side of the half gear contacts one side of the gear rod, which will drive the gear rod and the T-block to slide upward on the inner wall of the T-slot, and the connecting rod is driven by the T-block to make the round rod move upward inside the round block to push the formed shock-absorbing pad inside the mold groove out of the mold groove part, and separate the shock-absorbing pad from the mold groove, so that the staff can take out the shock-absorbing pad, thereby improving the convenience when using the press molding device, and then the half gear moves away from the surface of the gear rod, and the T-block and the round rod will fall due to gravity.

When the body is placed on the table, the suction cup at the bottom end of the U-shaped elastic sheet can be used to adsorb the body on the table, thereby avoiding as much as possible the sliding of the entire body when using the body, which affects the use.

[0017] Preferably, a plurality of convex strips are fixedly connected to both sides of the U-shaped elastic sheet, and the convex strips are linearly distributed on the outer surface of the U-shaped elastic sheet.

[0018] The effect achieved by the above components is that the U-shaped elastic sheet can be more conveniently moved by pinching the convex strip on the outer surface of the U-shaped elastic sheet to remove the U-shaped elastic sheet for replacement.
