An L-shaped plate 57 is fixed to one side of the fixed base 51, and a motor 58 is fixed to one side of the L-shaped plate 57. The motor 58 is controlled by an external switch and is electrically connected to an external power supply. A fixed block 59 is fixed to the output end of the motor 58, and a sliding rod is slidably connected to the inner surface of the fixed block 59. 510, one end of the sliding rod 510 passes through the fixed block 59 and extends to the outside of the fixed block 59, the other end of the sliding rod 510 is fixed with an L-shaped block 511, one side of the L-shaped block 511 is rotatably connected to one side of the sliding sleeve 54, the outer surface of the sliding rod 510 is sleeved with a spring 512, one end of the spring 512 is fixed to one side of the L-shaped block 511, and the other end of the spring 512 is fixed to one side of the fixed block 59, and a shovel plate 513 is provided on one side of the movable seat 56. When the shovel plate 513 moves horizontally, it can be inserted between the upper mold plate and the composite material. When it moves downward, the adhered composite material can be shoveled off to achieve quick and complete demoulding.

[0033] By setting up the demoulding mechanism 5 moving along the rectangular track and utilizing the shovel plate 513 to move along the rectangular track, the composite material adhered to the upper mold plate 10 can be quickly demoulded by scraping, thereby solving the problem of the composite material HP-RTM adhering to the mold plate after molding, which is inconvenient, inefficient and complete. The high degree of automation and high demoulding efficiency greatly improve the production efficiency.

[0034] A cylinder 8 is fixed on the top of the base 1. The cylinder 8 is controlled by an external switch and is electrically connected to an external power supply. The output end of the cylinder 8 passes through the bottom of the molding box 3 and extends to the interior of the molding box 3. The output end of the cylinder 8 is fixed with a lower mold plate 9.

[0035] An upper mold plate 10 is fixed on the top wall of the molding box 3. When the cylinder 8 drives the lower mold plate 9 to move upward, it is molded together with the upper mold plate 10 to mold the composite material, so that the composite material is pressed and formed. The bottom of the pusher plate 72 is slidably connected to the top of the lower mold plate 9.

[0036] Based on Example 1, see Figure 3 and Figure 5 As shown, a shaking-off and anti-sticking component 6 for shaking off the composite material adhered to the shovel plate 513 is provided between the fixed block 59 and the side plate 4.

The top of the protrusion 66 contacts and squeezes the inner surface of the wave groove 64. When the connecting plate 63 moves horizontally, it drives the protrusion 66 to move back and forth up and down in the wave groove 64, thereby driving the connecting plate 63 to shake up and down.

[0039] By shaking off the anti-sticking component 6, after the composite material HP-RTM is demolded using the shovel plate 513, the composite material HP-RTM adhered to the shovel plate 513 can be shaken off and fall onto the lower mold plate 9, effectively preventing the composite material HP-RTM from adhering to the shovel plate 513 after demolding, thereby facilitating the subsequent discharge of the composite material HP-RTM.

[0040] Based on Example 2, see Figure 3 and Figure 6 As shown, a pushing mechanism assembly 7 is provided on the side panel 4 for pushing out the composite material after demolding. The pushing mechanism assembly 7 includes two moving rods 71 ​​slidably connected to one side of the side panel 4. One end of the two moving rods 71 ​​passes through the side panel 4 and extends to the outside of the side panel 4.

[0041] A push plate 72 is fixed between one end of the two moving rods 71. When the push plate 72 moves, it can push out the composite material on the lower mold plate 9 to realize unloading. A square plate 73 is fixed between the other ends of the two moving rods 71. The outer surfaces of the two moving rods 71 ​​are both provided with spring three 74. The setting of spring three 74 can drive the moving rod 71 and the push plate 72 to reset.

[0042] One end of the two springs 3 74 is fixed to one side of the square plate 73 , and the other end of the two springs 3 74 is fixed to one side of the side plate 4 . A folding plate 75 is fixed to the top of the square plate 73 , and one side of the folding plate 75 contacts and squeezes one side of the installation box 61 .

[0043] Through the setting of the pushing mechanism assembly 7, when the moving seat 56 on the rectangular track moving demoulding mechanism 5 moves along the rectangular track and moves horizontally upward, it can drive the folding plate 75 and the pushing plate 72 to move, and then push the composite material HP-RTM on the lower mold plate 9 to achieve unloading. When the moving seat 56 moves downward, the spring three 74 can drive the pushing plate 72 to reset. The entire pushing process does not require manual operation. It is linked with the rectangular track moving demoulding mechanism 5 and can achieve the functions of demoulding, shaking off and pushing through a motor 58, which greatly simplifies the production process, reduces manual intervention, and significantly improves production efficiency and automation level.

[0044] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] During operation, the HP-RTM raw material is placed on the lower mold plate 9, and the cylinder 8 is started to drive the lower mold plate 9 to move upward, and then cooperate with the upper mold plate 10 to mold the HP-RTM raw material. When the molded composite material adheres to the upper mold plate 10, the motor 58 is started to drive the fixed block 59 to rotate, and then the fixed block 59 drives the slide bar 510 and the L-shaped block 511 to rotate, and then the L-shaped block 511 drives the moving seat 56 to slide downward. As the motor 58 drives the slide bar 510 to rotate, the moving seat 56 moves along the rectangular track, and when the moving seat 56 moves horizontally, it drives the shovel plate 513 to shovel into the upper mold plate When the movable seat 56 moves downward, the composite material is driven to be demoulded downward. When the movable seat 56 is reset horizontally, the connecting plate 63 is driven to contact and extrude with the protrusion 66. When the connecting plate 63 moves, the spring 2 62 will shake, and the composite material adhered to the shovel plate 513 will be shaken and dropped onto the lower mold plate 9. When the movable seat 56 moves horizontally, the mounting box 61 drives the folding plate 75, the square plate 73, the moving rod 71, and the pushing plate 72 to move, and then squeezes the compression spring 3 74. When the pushing plate 72 moves further, the composite material is pushed out. When the movable seat 56 moves downward, the spring 3 74 drives the pushing plate 72 to reset.
