[0013] Beneficial effects

[0014] This invention provides a high-performance molding die for processing carbon fiber sheets. Compared with the prior art, it has the following advantages:

[0015] (1) By setting up a pressure storage mechanism, the push block is repeatedly squeezed and the solid block is reset by the spring, so that the piston rod moves up and down inside the solid cylinder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a molding die for processing high-performance carbon fiber plates.

[0023] Example 1:

[0024] The device includes a lower mold 1, with an upper mold that can move up and down on its top. A pressure accumulator mechanism is provided on the body of the lower mold 1, comprising a pressure accumulator chamber 2 and a groove 3. An air pump can be connected to the pressure accumulator chamber 2 for pressure replenishment, and a pressure sensor can be installed inside the pressure accumulator chamber 2 to monitor the internal air pressure and ensure sufficient air pressure for demolding. The pressure accumulator chamber 2 is located inside the body of the lower mold 1, and the groove 3 is located on the outer surface of the lower mold 1. A fixed cylinder 4 is fixedly connected inside the groove 3, and a piston rod 5 is slidably connected inside the fixed cylinder 4. The piston of the piston rod 5 can compress air into the pressure accumulator chamber 2 for storage. One end of the piston rod 5 penetrates the body of the fixed cylinder 4 and extends into the groove 3. A fixed block 6 is fixedly connected to one end of the piston rod 5, and a push block 7 is movably connected to the outer surface of the fixed block 6. Both the push block 7 and the fixed block 6 are triangular. The two are identical in shape and size, and their beveled edges fit together to achieve oblique compression. A compression spring 9 is sleeved on the outside of the piston rod 5. The spring 9 rebounds to facilitate the reset of the piston rod 5. The two ends of the compression spring 9 are fixedly connected to the outer surfaces of the solid cylinder 4 and the solid block 6, respectively. The solid cylinder 4 has two sets of one-way valves 10 running through it. Each set of one-way valves 10 has two valves. Each set of one-way valves 10 can connect the pressure accumulator 2, the solid cylinder 4 and the outside, so that outside air can flow into the pressure accumulator 2 in one direction. The interior of each set of two one-way valves 10 is connected to the interior of the groove 3 and the interior of the pressure accumulator 2, respectively. The interior of the pressure accumulator 2 is connected to the exhaust pipe 11. One end of the exhaust pipe 11 is connected to the air passage on the lower mold 1 body. As a preferred embodiment, a solenoid valve can be installed on the exhaust pipe 11 to control the outflow of high-pressure air inside the pressure accumulator 2.

[0025] In this embodiment, the pusher 7 reciprocates inside the groove 3, thereby pushing the solid block 6 downward by oblique compression, so that the piston rod 5 follows the movement, thereby forcing the air in the lower part of the solid cylinder 4 into the accumulator 2. When the pusher 7 releases the compression of the solid block 6, the compression spring 9 rebounds, causing the solid block 6 to drive the piston rod 5 to rise and reset, thereby forcing the air in the upper part of the solid cylinder 4 into the accumulator 2. At the same time, the air pressure sensor monitors the air pressure inside the accumulator 2. If the air pressure is lower than expected, the external air pump is directly pumped into the accumulator 2 to replenish the pressure. When demolding is required, the solenoid valve on the exhaust pipe 11 opens, and the high-pressure air inside the accumulator 2 flows into the air passage, pushing out the formed carbon fiber plate to achieve demolding.

[0026] Example 2:

[0027] The push block 7 is externally equipped with a drive assembly 8, which includes a slide 81. The slide 81 is made of a rectangular frame, and its width is adapted to the internal dimensions of the groove 3. The outer surface of the slide 81 is slidably connected to the inside of the groove 3, and the outer surface of the slide 81 is fixedly connected to the outer surface of the push block 7. The sliding end of a reciprocating screw 82 is fixedly connected through the body of the slide 81. The rotation of the reciprocating screw 82 can drive the slide 81 to slide back and forth, so as to realize the continuous pressing action of the push block 7. The outer surface of the reciprocating screw 82 is rotatably connected to the inside of the groove 3, and the screw of the reciprocating screw 82 is rotatably connected through a filter plate 83. The filter plate 83 supports the reciprocating screw 82 and can also filter the external environment. The air is filtered, and the outer surface of the filter plate 83 is fixedly connected to the inside of the groove 3. One end of the reciprocating screw 82 is fixedly connected to a sprocket 84, and the outer surface of the sprocket 84 is connected to a chain 85. The connection between the chain 85 and the sprocket 85 can be equipped with anti-detachment measures. One end of the sprocket 84 is fixedly connected to the upper mold, and the outer surface of the sprocket 84 is movably connected to a fixed pulley 86. The connection between the chain 85 and the fixed pulley 86 has an anti-detachment effect to improve the tension and tightness of the chain 84. The shaft end of the fixed pulley 86 is embedded and rotatably connected to the outer surface of the lower mold 1. The other end of the sprocket 84 is fixedly connected to a pendant 87. Both the fixed pulley 86 and the pendant 87 have a tension and tightness effect on the chain 85.

[0028] In this example, when the upper mold opens, the chain 85 is pulled upward, and through the meshing of the chain 85 and the sprocket 84, the sprocket 84 drives the reciprocating screw 82 to rotate, thereby causing the slide 81 to drive the push block 7 to slide back and forth to squeeze the solid block 6. At the same time, when the upper mold closes, the pendant 87 pulls the chain 85 downward by its own weight, which not only moves the chain 85 downward but also stretches the chain 85. Through the pinching of the chain 85 and the sprocket 84, the sprocket 84 drives the reciprocating screw 82 to rotate in the opposite direction, so that when the upper mold opens and closes, the piston rod 5 continuously compresses the outside air to increase the amount of air compression.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
