[0030] S2. Close the mold: Close the moving mold and the static mold on the manufacturing device together.

[0031] S3. Inject the plastic tray: Inject the raw material between the moving mold and the static mold and wait for the plastic tray to solidify and form.

[0032] S4. Demold: Release the limit on the plant fiber bar frame, then separate the moving mold and the static mold on the manufacturing device, and finally remove the plastic tray.

[0033] In this embodiment, as shown in the figure, the manufacturing device involved in steps S1 - S4 includes a bracket 1, and a static mold mechanism 2 is fixed on the inner wall of one side of the bracket 1. A plant fiber bar and its installation mechanism 3 are snap - connected to the inner wall of the static mold mechanism 2, and the plant fiber bar and its installation mechanism 3 are suction - connected to the static mold mechanism 2. A moving mold mechanism 4 is fixed on the other side of the bracket 1, and the moving mold mechanism 4 penetrates through the other side of the bracket 1. The static mold mechanism 2 and the moving mold mechanism 4 are used in combination to make the product into a tray shape. During injection molding, the plant fiber bar and its installation mechanism 3 will be embedded in the product, which can greatly improve the tensile strength of the product, significantly reduce the load deformation amount, and greatly reduce the cost.

[0034] In this embodiment, as Figure 1 and Figure 2 shown, the stationary mold mechanism 2 includes a stationary mold body 201, and a feeding valve 202 is fixed on the top of the stationary mold body 201. A first electric telescopic rod 203 is fixed on one inner wall of the bracket 1, and a first piston 205 is fixed at one end of the first electric telescopic rod 203. A first oil groove 204 is formed in the side wall of the stationary mold body 201. The first piston 205 is slidably connected in the first oil groove 204.

After the electromagnet 211 is powered on, the electromagnet 211 automatically attracts the iron block 304, and the locking block 303 automatically snaps into the first branch channel 208, facilitating the locking of the plant fiber bar main body 301. Before demolding, the push rod 210 pushes the locking block 303 into the sleeve 302. After the electromagnet 211 is powered off and the push rod 210 is removed, the demolding operation can be performed.

The second electric telescopic rod 401 penetrates through the other side of the bracket 1 and is connected to the moving plate 402. One side of the moving plate 402 is fixed with a moving die body 403. The moving plate 402 can move left and right under the telescopic action of the second electric telescopic rod 401, thereby driving the moving die body 403 to move left and right, facilitating the use or removal of the moving die body 403.

[0039] In this embodiment, as Figure 2 shown, a third electric telescopic rod 404 is fixed on the moving plate 402. The third electric telescopic rod 404 penetrates through one side of the moving plate 402 and the moving die body 403 and is connected to a third piston 405. A second oil groove 406 is formed in the moving die body 403. The third piston 405 is slidably connected in the second oil groove 406. The third piston 405 can move left and right under the telescopic action of the third electric telescopic rod 404. When the third piston 405 moves to the right, hydraulic oil can be pumped into the second oil groove 406.

A second branch channel 408 is formed on the outer side wall of the moving die body 403, and the second branch channel 408 is communicated with the hydraulic channel 407. A fourth piston 409 is slidably connected in the second branch channel 408, and a moving block 410 is fixed on the outer side of the fourth piston 409. Hydraulic oil is stored in the second branch channel 408. Before demolding, the third piston 405 moves to the right, the fourth piston 409 moves, and the moving block 410 moves accordingly and retracts into the second branch channel 408. Finally, the plastic tray can be successfully removed.

[0041] The usage method and advantages of the present invention: The preparation process of the plastic tray with built-in fiber ribs is as follows:

[0042] As Figures 1 to 5Shown as follows: First, place the main body 301 of the plant fiber reinforcement on the inner side of the static mold body 201 and make the sleeves 302 correspond to the locking blocks 303 one by one. After energizing the electromagnet 211, the electromagnet 211 automatically attracts the iron block 304, and the locking block 303 is stuck into the second branch channel 408 to lock the main body 301 of the plant fiber reinforcement. Then, the moving plate 402 and the moving mold body 403 are moved leftward as a whole. The moving mold body 403 is closed with the static mold body 201. Open the injection valve 202 to inject material between the moving mold body 403 and the static mold body 201. The plant fiber reinforcement and its installation mechanism 3 are embedded in the raw material. The moving block 410 is a mold for making holes in the plastic tray. After the raw material is formed, the first piston 205 moves rightward, and the second piston 209 and the push rod 210 move rightward to completely push the locking block 303 into the sleeve 302. After powering off the electromagnet 211, withdraw the push rod 210 into the first branch channel 208. Then, the moving plate 402 and the moving mold body 403 move rightward as a whole and reset. Next, the third piston 405 moves rightward, the fourth piston 409 slides, and the moving block 410 moves accordingly and retracts into the second branch channel 408.
