[0003] When the existing molding device for composite material processing is used, the sealing effect is not very ideal when applying pressure to the composite material, which causes the glue inside the mold to easily penetrate through the gap to the outside, thereby causing material waste and affecting the quality of the composite material.

[0004] In addition, the molding device in the prior art also relies on natural cooling for temperature reduction, which has the disadvantages of difficulty in cooling, long cooling cycle and low efficiency. Utility Model Content

[0005] In view of the above analysis and in response to the deficiencies in the prior art, the utility model aims to provide a molding device for composite material processing, which solves at least one of the problems existing in the molding device in the prior art, such as glue seepage, poor sealing effect, long cooling cycle, and low efficiency.

[0006] The purpose of this utility model is mainly achieved through the following technical solutions:

[0028] (1) The utility model can improve the sealing performance between the mold and the pressure plate of the molding device for composite material processing by installing a sealing airbag. After the pressure plate moves to the inside of the mold, the telescopic rod works to push the rubber block to move. When the rubber block moves, it compresses the air inside the sealing chamber.

The extracted water flows into the water flow trough. When the water flows in the water flow trough, it will carry the heat on the mold and flow, thereby improving the heat dissipation efficiency of the mold.

[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0045] like Figure 1-Figure 7 As shown, the utility model discloses a molding device for composite material processing, comprising: a concave mold 6 and a pressure plate 4; the concave mold 6 can be matched and embedded with the pressure plate 4;

[0046] The side wall of the pressure plate 4 is provided with an annular groove 401 , and an annular sealing airbag 10 with adjustable volume is provided in the annular groove 401 .

[0047] During implementation, when the pressure plate 4 is engaged with the concave mold 6, a thermoforming chamber is formed between the pressure plate 4 and the concave mold 6, and the annular sealing airbag 10 expands and seals the annular groove 401 and the inner wall of the concave mold 6, thereby achieving sealing of the thermoforming chamber and preventing the molten composite material from overflowing.

[0048] Compared with the prior art, the utility model can improve the sealing between the mold and the pressure plate of the molding device for composite material processing by installing a sealing airbag, thereby achieving the purpose of improving the sealing and solving the problems of glue seepage and poor sealing effect in the molding device in the prior art.

[0049] Specifically, a concave strip groove 11 is provided on the side of the pressure plate 4 opposite to the concave mold 6, and a pneumatic chamber 14 connected to the annular sealing airbag 10 is fixedly provided in the strip groove 11; the air pressure change in the pneumatic chamber 14 can cause the air pressure change in the annular sealing airbag 10, thereby realizing the volume adjustment of the annular sealing airbag 10.

[0050] Specifically, an elastic sealing block 13 is provided in the pneumatic chamber 14 , and the elastic sealing block 13 can slide relative to the pneumatic chamber 14 to divide the pneumatic chamber 14 into a sealed first chamber 1401 with adjustable volume and a second chamber 1402 ; the first chamber 1401 is connected to the annular sealing airbag 10 .

[0051] During implementation, when the elastic sealing block 13 reciprocates, causing the volume of the first chamber 1401 to decrease, the gas in the first chamber 1401 enters the annular sealing airbag 10, causing the volume of the annular sealing airbag 10 to increase; similarly, when the volume of the first chamber 1401 increases, the gas in the annular sealing airbag 10 enters the first chamber 1401, causing the volume of the annular sealing airbag 10 to decrease.

[0052] Specifically, the elastic sealing block 13 may be made of rubber.

[0053] Specifically, the elastic sealing block 13 is located in the second chamber 1402 and is connected to a telescopic rod 12 on one side. The fixed end of the telescopic rod 12 is fixed to the strip groove 11, and the movable end is fixedly connected to the elastic sealing block 13. Under the action of the telescopic rod 12, the elastic sealing block 13 can reciprocate relative to the pneumatic chamber 14 to adjust the volume of the first chamber 1401 and the second chamber 1402; a connecting pipe 15 is provided on the side where the first chamber 1401 is connected to the annular sealing airbag 10, which is used for gas to circulate in the first chamber 1401 and the annular sealing airbag 10.

[0054] Compared with the prior art, the utility model can improve the sealing between the mold and the pressure plate of the molding device for composite material processing by installing a sealing airbag. After the pressure plate moves to the inside of the mold, the telescopic rod is operated to push the rubber block to move. When the rubber block moves, the air inside the sealed chamber is compressed. The compressed air flows into the interior of the sealing airbag through the connecting pipe, thereby expanding the volume of the sealing airbag and sealing the gap between the mold and the utility model, thereby achieving the purpose of improving the sealing, and solving the problems of glue seepage and poor sealing effect in the molding device in the prior art.

[0055] Specifically, the molding device is further provided with an L-shaped support frame 2 and a workbench 1;

[0056] One end of the L-shaped support frame 2 is fixedly connected to the workbench 1, and the other end is provided with a hydraulic rod 3;

[0057] The fixed end of the hydraulic rod 3 is fixedly connected to the L-shaped support frame 2, and the movable end is fixedly connected to the pressure plate 4;

[0060] Preferably, the concave mold 6 is fixedly connected to the workbench 1 via a square frame 5 arranged around its own side wall.

[0061] Preferably, the square frame 5 and the strip groove 11 can be made of heat-insulating materials to reduce the heat dissipation loss of the mold during heating and protect the non-heating area in the device from being affected by high temperature.

[0062] Preferably, a heat dissipation gap 501 is provided between the square frame 5 and the side wall of the concave mold 6, and the workbench 1 is inlaid with a cooler 16, which is connected to the heat dissipation gap 501 and can generate flowing air. After the flowing air enters the heat dissipation gap, it accelerates the cooling of the concave mold 6 in the cooling stage.

[0063] Preferably, if Figure 5 As shown, an exhaust pipe 19 is provided on the other side of the workbench 1 inlaid with the cooler 16 . The exhaust pipe 19 is connected to the heat dissipation gap 501 , and can discharge the flowing air that has undergone heat exchange in the heat dissipation gap 501 , thereby realizing unimpeded heat convection in the heat dissipation gap 501 .

[0064] Specifically, Figure 6 As shown, the cooler 16 is provided with holes 17 in an array, a fan 18 is installed inside the cooler 16, and the output end of the fan 18 extends to the inside of the square frame 5. The outside air flows into the cooler 16 through the holes 17. The fan 18 generates wind when working, and the wind flows into the heat dissipation gap 501 inside the square frame 5, thereby cooling the concave mold 6 inside the square frame 5.

[0065] Specifically, Figure 5 , Figure 6 As shown, a water tank 20 and a water pump 21 are fixedly installed inside the cooler 16, and a water flow trough 22 is installed on the square frame 5; the input end of the water pump 21 extends to the inside of the water tank 20, and the output end of the water pump 21 is connected to one end of the water flow trough 22, and a return pipe 23 is installed at the other end of the water flow trough 22, and the return pipe 23 is connected to the water tank 20.

[0066] During implementation, the water pump 21 works to extract water from the water tank 20, and the extracted water flows into the water flow trough 22. When the water flows in the water flow trough 22, it will carry the heat on the concave mold 6, thereby improving the heat dissipation efficiency of the concave mold 6. The water will flow back into the water tank 20 through the reflux pipe 23 for storage.

[0067] Compared with the existing technology, air cooling and water cooling can improve the heat dissipation efficiency of the mold and the internal composite materials, avoid scalding the staff due to excessive temperature, improve the practicality of the molding device for composite material processing, reduce the cooling time of the mold, facilitate sample removal, and improve production efficiency.
