The equipment used to protect the calf from injury mainly disperses and buffers the pressure and impact force applied to the athlete's calf, thereby protecting the athlete from injury during the movement; however, the existing shin guards have problems such as heavy weight, poor strength, and low wearing comfort, and further improvement is urgently needed.

[0034] To solve the problems existing in the above-mentioned calf protection plate, the present invention proposes a lightweight calf protection plate preparation structure.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 , including a die assembly for clamping, a punch 9 disposed inside the die assembly, and a product body 7 disposed between the punch 9 and the die assembly; a forming groove 2 is formed at the middle position inside the die assembly, the punch 9 is adapted to the forming groove 2, the product body 7 is laid outside the punch 9, the punch 9 presses the product body 7, one side of the product body 7 fits against the inner wall of the forming groove 2, the die assembly includes a first die 1 and a second die 8 that clamps with the first die 1, and the product body 7 is made of a lightweight material.

[0036] As Figure 1 、 Figure 2 and Figure 3As shown, the female die assembly is set as the outer die, the male die 9 is set as the inner die, and the product body 7 is clamped between the inner die and the outer die;

[0037] The female die assembly is divided into two parts, the first female die 1 and the second female die 8. They can form a whole only when they are closed, and at the same time, a complete forming groove 2 can be formed. When not closed, half of the forming groove 2 is respectively opened in the middle of the first female die 1 and the second female die 8, and the male die 9 is adapted to the overall forming groove 2;

[0038] Before the product body 7 is formed, it is first laid on the outer surface of the male die 9, and then the male die 9 is placed inside the forming groove 2, so that the product body 7 is clamped by the male die 9 and the female die assembly, and the product body 7 is extruded inside the forming groove 2. And inflate the male die 9, and the male die continuously expands and extrudes the product body 7 to ensure the shape and forming quality of the product;

[0039] At the same time, the material of the product body 7 is but not limited to Kevlar fiber, glass fiber, and carbon fiber.

[0040] Specifically, the product body 7 is cut into prepregs according to the developed dimensions of the product shape. Two Kevlar fiber prepregs with dimensions of about 350×220mm, two glass fiber prepregs with dimensions of about 350×220mm, and two carbon fiber twill fabric prepregs with dimensions of 350×220 are cut respectively. When the product body 7 is clamped in the male die 9 and the female die assembly, the forming temperature is set to 130 - 150°C, the pressure of the molding press is set to 2 - 10MPa, the pressure of the airbag is set to 0.6 - 0.9MPa, and the forming time is 60 - 120min.

[0041] Please refer to Figure 1 , on the side where the first female die 1 and the second female die 8 are mutually attached, there is a docking component. The docking component includes a first docking part 4 provided at the top of the female die assembly and second docking parts 5 provided on both sides of the female die assembly. The first docking part 4 and the second docking parts 5 are arranged along the up and down length direction of the female die assembly. Both the first docking part 4 and the second docking parts 5 include a docking groove and a docking block. The docking groove or the docking block is respectively provided on the first female die 1 or the second female die 8. Each docking block is correspondingly arranged with each docking groove, and the docking block is clamped inside the docking groove.

[0042] As Figure 1As shown in the figure, on one side where the first female mold 1 and the second female mold 8 are in contact with each other, a first docking part 4 and a second docking part 5 are provided. The first docking part 4 is located at the top of the first female mold 1 and the second female mold 8, and the second docking parts 5 are distributed at positions close to both sides of the first female mold 1 and the second female mold 8, ensuring that when the first female mold 1 and the second female mold 8 are closed, they are guided and positioned. Both the first docking part 4 and the second docking part 5 are composed of a docking groove and a docking block. Among them, the docking groove or the docking block can be arranged on the first female mold 1 or the second female mold 8, but they cannot be the same. It must be that the docking groove and the docking block correspond to each other to ensure that the docking block can be clamped inside the docking groove.

[0043] Please continue to refer to Figure 1 , docking holes 6 and docking rods are respectively provided at the four corners on the side where the first female mold 1 and the second female mold 8 are closed.

[0044] As Figure 1 shown, the design of the docking holes 6 and the docking rods can ensure the positioning of the four corners of the first female mold 1 and the second female mold 8, further ensuring the accuracy of mold closing and preventing skewing.

[0045] Please refer to Figure 1 and Figure 2 , a plurality of air pipe holes 3 are opened at the top position of the female mold assembly corresponding to the forming groove 2. The air pipe holes 3 are communicated with the forming groove 2. The male mold 9 is set as a silica gel airbag, and an inflation hole is provided at the position of the silica gel airbag corresponding to the air pipe holes 3.

[0046] As Figure 1 and Figure 2 shown, the male mold 9 is a silica gel airbag that can expand. An inflation hole is provided at the position of the silica gel airbag corresponding to the air pipe holes 3. When the male mold 9 is arranged inside the forming groove 2, through the air pipe holes 3, the air pipe is docked with the inflation hole to inflate the male mold 9, causing the male mold 9 to expand and become larger, squeezing the product body 7 against the inner wall of the forming groove 2 to clamp the product body 7 and ensure the forming of the product body 7.

[0047] When using the present utility model, the product body 7 is laid on the outside of the male mold 9. After laying, the male mold 9 is placed inside the forming groove 2, so that the product body 7 is clamped by the male mold 9 and the female mold assembly. And through the air pipe holes 3, the air pipe is docked with the inflation hole of the male mold 9 to inflate the male mold 9. The male mold 9 continuously expands and squeezes the product body 7, causing the product body 7 to be continuously squeezed against the inner wall of the forming groove 2 to ensure the shape and forming quality of the product.
