Description
Technical Field
[0001] The utility model relates to the field of foam aluminum production, in particular to a demoulding device for foam aluminum production. Background Technique
[0002] Foam aluminum was invented in 1959. After adding additives to pure aluminum or aluminum alloy, it is made through a foaming process, and has both the characteristics of metal and bubbles. It has a small density, strong high-impact absorption ability, high temperature resistance, strong fire prevention performance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding performance, strong weather resistance, filtering ability, easy processing, easy installation, high forming accuracy, and can be surface coated. At present, the main preparation process of foam aluminum is the melting and foaming method. After melting and foaming, the foam aluminum product is obtained through the processes of die forming and cutting.
[0003] In the prior art, the Chinese utility model patent with the application number: 2022214651 and the patent name: a foam aluminum forming and demoulding device describes that "through the integrated design of a forming die, a cooling device, and a demoulding device, the continuous production requirements can be met. When forming, the aluminum liquid is placed into the forming die, and the temperature is reduced through the cooling device. After the temperature reduction is completed, the push plate is driven by an electric push rod, and the push plate pushes the ejector rod to eject the formed foam aluminum out of the die. Then, the foam aluminum can be transferred using a gripper. The entire use process of this device is simple, the equipment utilization rate is high, the forming and demoulding efficiency is high, and thus the production efficiency of foam aluminum is improved". The above device uses the ejector rod to eject the foam aluminum. However, due to the small acting surface of the ejector rod, the force cannot be evenly applied to the foam aluminum, resulting in excessive local force on the foam aluminum and causing damage to the foam aluminum when ejecting it. Moreover, since the foam aluminum will adhere to the inner wall of the die when solidifying and forming, the demoulding is rather troublesome. The above device cannot perform pretreatment on it but rigidly ejects the foam aluminum, which will not only cause product damage but also affect the demoulding efficiency. In summary, the present application now proposes a demoulding device for foam aluminum production to solve the above problems. Content of the Utility Model

The sliding rod 311 is fixedly connected between the left and right side walls of the inner cavity of the chute 310. The sliding rod 311 is used to limit the slider 312 and install the second return spring 313. The slider 312 is slidably connected to the outer side wall of the sliding rod 311.

[0030] As an improved solution to the above solution, the control panel 110, the electric telescopic rod 114, and the servo motor 216 are electrically connected.
[0031] Workflow: Pour the raw material into the lower mold 111, start the electric telescopic rod 114 through the control panel 110, and the electric telescopic rod 114 drives the upper mold 115 to move downward through the cooperation of the T-shaped groove 330 and the T-shaped limiting block 331 to cooperate with the lower mold 111 to shape the raw material;
[0032] During the movement of the upper mold 115, the knocking block 315 contacts the extrusion block 320. The extrusion block 320 causes the knocking block 315 to move through extrusion, creating a distance between the knocking block 315 and the lower mold 111. At the same time, the knocking block 315 drives the slider 312 to move through the L-shaped rod 314, stretching the second return spring 313. When the knocking block 315 disengages from the extrusion block 320, the second return spring 313 rebounds, driving the knocking block 315 to reset and knock on the lower mold 111. When the upper mold 115 descends to shape the raw material, the knocking of the knocking block 315 can make the raw material in the lower mold 111 more evenly distributed in the lower mold 111. When the upper mold 115 rises after the shaping is completed, the knocking can create a gap between the foamed aluminum and the lower mold 111, making it more convenient to demold.
[0033] After the shaping is completed, the servo motor 216 is started through the control panel 110. The output shaft of the servo motor 216 rotates, and through the cooperation of the lead screw 217 and the traction block 218, the top block 219 is driven to move leftward. The top block 219 increases the friction with the rubber wheel 214 through the anti-slip pad on the top, so that the rubber wheel 214 rolls upward along the top block 219. Then, the ejector plate 210 is driven to move upward through the ejector rod 211 to eject the foamed aluminum. At the same time, the mounting plate 212 squeezes the first return spring 213 to make the first return spring 213 contract, so that after the ejection is completed, the first return spring 213 rebounds to drive the ejector plate 210 to reset.
