Description

Technical Field

[0002] Hot pressing forming equipment is a mechanical device that forms materials under high temperature and high pressure. The materials processed by hot pressing forming are usually metal or plastic materials. Hot pressing forming equipment is widely used in industries such as automobiles, aerospace, and electronics, especially in the processing of heat dissipation aluminum plates in the manufacturing of new energy vehicles.

[0003] However, in the prior art, when the hot pressing forming equipment performs hot pressing operations, the precise control of temperature is the key point to improve the processing quality of products. The existing hot pressing forming equipment usually heats the mold by using an electric heating plate to raise the temperature of the mold. In the actual production process, because the upper part of the mold has a large exposed area and a fast heat dissipation speed, in order to make the surface temperature of the mold reach the set temperature, the set temperature of the electric heating plate should be higher than the set temperature of the mold surface. However, when the upper mold presses the lower mold for mold closing, the overall heat dissipation speed of the mold will decrease, and the balance between the heat supply and temperature rise of the electric heating plate and the heat dissipation and temperature drop of the mold is broken, resulting in the temperature inside the mold being higher than the set temperature, causing the temperature of the material heating to be too high and easily reducing the product quality.

The plurality of heat dissipation fans 31 are evenly distributed on both sides of the second mold 15. The heat dissipation fans 31 are located above the heat dissipation plates 32.

[0023] Next, specifically describe the specific settings and functions of this embodiment. The electric heating plate 12 is used to heat the first mold 13 and the aluminum plate placed inside it to a set temperature. During the heating process, the temperature is monitored in real time through the temperature sensors 16. Subsequently, the second mold 15 is pushed by the hydraulic cylinder 14 to perform hot pressing and forming processing on the aluminum plate placed inside the first mold 13;

[0024] When the second mold 15 and the first mold 13 are closed, the heat dissipation speed of the upper part of the first mold 13 decreases. When the temperature sensors 16 detect that the temperature on the surface of the first mold 13 is too high, at this time, the heat dissipation fans 31 are used to ventilate the surface of the heat dissipation plates 32 to accelerate the heat dissipation efficiency of the heat dissipation plates 32.

[0026] The effect achieved by the entire embodiment is that the hydraulic cylinder 14 is used to push the second mold 15 to perform hot pressing forming on the aluminum plate placed inside the first mold 13.

During the heating process, the temperature is monitored in real time by the temperature sensor 16. Subsequently, the hydraulic cylinder 14 is used to push the second mold 15 to perform hot pressing forming on the aluminum plate placed inside the first mold 13. During the downward movement of the second mold 15, the guiding tube 21 slides along the first guiding rod 22 to limit the movement of the second mold 15. At the same time, the guiding plate 25 slides along the second guiding rod 24 to further limit the movement of the second mold 15.

[0028] When the second mold 15 and the first mold 13 are closed, the heat dissipation speed of the upper part of the first mold 13 decreases. When the temperature sensor 16 detects that the temperature on the surface of the first mold 13 is too high, at this time, the ventilation fan 31 is used to ventilate the surface of the heat dissipation plate 32 to accelerate the heat dissipation efficiency of the heat dissipation plate 32. The heat inside the first mold 13 is evenly transferred to the surface of the heat dissipation plate 32 through the heat absorption plate 35 and the heat conduction plate 34 for ventilation and heat dissipation.
