[0028] Specifically, Figure 1 and Figure 2 As shown, when the upper mold 12 rises, the spring 2 and the hinge rod 17 will cause the connecting plate 16 to rise, so that the top plate 20 at the top of the fixed block 21 can push out the router plastic part inside the mold cavity 13, thereby preventing the router plastic part from being stuck inside the mold cavity 13 and being inconvenient to demold. The damper 22 can limit the spring 2 to prevent the connecting plate 16 from shaking. When the upper mold 12 descends, the limiting rod 15 at the bottom end of the upper mold 12 will be embedded in the sleeve 18 to cause the connecting plate 16 to squeeze the spring 2.

[0029] Embodiment 2: A servo motor 23 is installed at the rear end of the protective shell 4, a connecting shaft 25 is fixedly connected to the output end of the servo motor 23, a gear 24 is fixedly connected to the front end of the connecting shaft 25, a tooth plate 11 is arranged on the right side of the gear 24, and an upper mold 12 is fixedly connected to the right side of the tooth plate 11;

[0030] The outside of the gear 24 is processed with a tooth block, and the left side of the tooth plate 11 is processed with a tooth block of the same size as the outside of the gear 24. The gear 24 and the tooth plate 11 cooperate with each other. The two ends of the left side of the inside of the protective shell 4 are provided with a limited slide groove 10. The two ends of the tooth plate 11 are fixedly connected to the limited block 5, and the limited block 5 slides up and down inside the limited slide groove 10;

[0031] Specifically, Figure 1 , Figure 3 and Figure 4As shown, start the servo motor 23, and the servo motor 23 can drive the gear 24 to rotate through the connecting shaft 25. Since the gear 24 and the tooth plate 11 cooperate with each other, and the upper mold 12 is fixedly connected to the right side of the tooth plate 11, the rotation of the gear 24 can make the tooth plate 11 drive the upper mold 12 to rise and fall, so that the mold cavity 13 can be opened and closed conveniently. The limiting slide groove 10 limits the tooth plate 11 through the limiting block 5 to prevent the tooth plate 11 and the tooth block outside the gear 24 from being misaligned, which affects the lifting and lowering of the tooth plate 11 and the upper mold 12.

[0032] Embodiment 3: A support plate 6 is fixedly connected to the left side inside the protective shell 4, a hydraulic cylinder 7 is installed on the top of the support plate 6, a mounting plate 8 is installed on the top of the hydraulic cylinder 7, a limit block 9 is fixedly connected to the top of the mounting plate 8, the limit block 9 is embedded between the tooth blocks outside the gear 24, a reserved groove is opened on the right side of the upper mold 12, a limit slide bar 14 is fixedly connected to the right side of the top of the base 1, and the upper mold 12 slides outside the limit slide bar 14 through the reserved groove;
