Description

Technical Field

[0001] The utility model belongs to the technical field of molds, in particular to a pressure composite mold structure with heating and cooling functions. Background Art

[0002] In the automotive interior industry, it is necessary to cover the outer surface of the product with a decorative layer, such as leather or fabric, to improve comfort and aesthetics. This technology of combining multiple layers of materials into one is called pressure lamination technology.

[0003] Most composite technologies require spraying glue on the material layer, first applying pressure to fully infiltrate the glue, then heating the glue to activate it, and finally cooling the glue. How to quickly and evenly achieve heating and cooling is the key to improving composite strength.

[0004] The mainstream composite equipment in the current automotive interior industry are as follows:

[0005] Mold water heating + air cooling: The cooling speed is slow and there is a risk of debonding;

[0006] Oven heating + mold temperature water cooling: uneven heating, activation effect is difficult to guarantee;

[0007] Integrated mold temperature water heating / cooling: As described in "CN202022862835-A kind of automobile instrument panel covering hot and cold pressing equipment", a lower mold carrying parts is successively docked with two upper molds. The first upper mold is a hot mold and the second upper mold is a cold mold. This is the pressure composite equipment with the best comprehensive performance at present, but there are still the following contradictions: if the temperature of the lower mold is set too high, the cooling speed will be reduced when combined with the cold mold; if the temperature of the lower mold is set too low, the heating speed will be reduced when combined with the hot mold.

[0040] A top plate 4 is installed in the middle of the lower mold body 1; the top plate 4 is installed on the top plate cylinder 8 through the top plate cylinder flange 6, and the top plate cylinder 8 drives the top plate 4 to move up and down; the top plate cylinder 8 is installed on the lower mold body 1; the cold air duct 7 passes through the top plate cylinder flange 6 and is connected to the top plate 4.

[0041] Wherein, the top plate cylinder 8 is an electric cylinder or a hydraulic cylinder or a gas-liquid booster cylinder.

[0042] See also Figure 2 The top plate 4 is a hollow structure with a blowing hole 5 on the side. When the top plate 4 moves to the bottom, it is supported by the mold concave platform 14 on the lower mold body 1. After the high-pressure cooling gas is introduced into the cold air duct 7, the cold air 13 is blown to the surface of the part 3 through the blowing hole 5 to cool it down.

[0043] The portion where the top plate cylinder flange 6 cooperates with the lower mold body 1 becomes a flange guide 12; the top plate cylinder flange 6 and the flange guide 12 cooperate with each other to achieve precise guidance of the top plate 4 moving up and down.

[0044] The material of the top plate cylinder flange 6 is stainless steel or carbon steel; the outside of the top plate cylinder flange 6 is covered with thermal insulation material; the material of the top plate 4 is aluminum alloy or copper alloy; the height of the top plate 4 is 2mm-30mm, preferably 5mm-10mm. The diameter of the blowing hole 5 is 0.5mm-5mm; the normal angle between the blowing hole 5 and the top plate 4 is 20°-80°, preferably 30-60°.

The existing technology is adopted to control the opening and clamping of the clamp 11 by the clamp clamping cylinder 10, and the overall up and down movement of the clamp 11 is controlled by the clamp lifting cylinder 9.

[0047] The working principle of the utility model is as follows:

[0048] When the lower mold and the hot mold 17 are connected, the top plate 4 is in the bottom state and is supported by the mold concave platform 14, and the heat of the lower mold body 1 is transferred to the top plate 4 through the mold concave platform 14, and then the lower mold body 1 and the top plate 4 jointly heat the lower surface of the part 3. The upper surface of the part 3 is heated by the hot mold 17 (such as Figure 3 In this process, the clamp lifting cylinder 9 is also in the bottom state, and the clamp clamping cylinder 10 makes the clamp 11 in the clamping state. At this time, the cold air pipe 7 does not pass the high-pressure cooling gas.

[0049] During the docking stage between the lower mold and the cold mold 15, first, the clamp clamping cylinder 10 opens the clamp 11, and then the clamp lifting cylinder 9 drives the clamp clamping cylinder 10 and the clamp 11 to rise at the same time; then the top plate cylinder 8 pushes the top plate 4 to move upward, and then the top plate 4 drives the part 3 to move upward, so that the part 3 is separated from the lower mold body 1, and the lower mold heating process ends. The clamp clamping cylinder 10 clamps the clamp 11 so that the part 3 fits firmly with the top plate 4. Finally, high-pressure cooling gas is introduced into the cold air duct 7, and the lower surface of the part 3 is sprayed from the blowing hole 5 for cooling. At this time, the upper surface of the part 3 is cooled by the cold mold 15.

[0050] In summary, the present invention achieves a function of perfect integration and seamless switching of heating and cooling within a mold, and has great applicability in the field of automobile interior mold manufacturing.
