Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] As shown in Figures 1 to 6 , the present application provides a vertically casted guardrail manufacturing mold, comprising:

[0026] An inner support seat 1, to which a plastic plate group 2 rotatable relative to the inner support seat 1 is attached, the plastic plate group 2 and the inner support seat 1 cooperate to form at least one plastic cavity 20, wherein the width above the plastic cavity 20 is greater than the width below the plastic cavity 20;

[0027] The plastic plate group 2 includes plastic side plates 21 respectively hinged on both sides of the inner support seat 1, and plastic edge plates 22 respectively hinged on both ends of the inner support seat 1, and a locking device 23 is arranged on the plastic side plate 21.

[0028] Specifically, the plastic plate group is composed of plastic side plates and plastic edge plates, which are both installed on the inner support seat through precise hinge mechanisms, allowing flexible rotation and adjustment within a certain range. The plastic side plate is responsible for the lateral shaping of the mold, and its surface is specially treated to improve wear resistance and corrosion resistance. The plastic edge plate defines the edge shape of the mold, ensuring the right angle and edge smoothness of the guardrail.

[0029] As shown in Figure 3 and Figure 4 , in this embodiment, the inner support seat 1 includes a base 11 and a plastic table 12 formed on the base 11, the plastic table 12 has a substantially trapezoidal cross section, a connecting base 13 is formed below the base 11, and a side connecting lug 131 for connecting the plastic side plate 21 and an edge connecting lug 132 for connecting the plastic edge plate 22 are arranged on the connecting base 13.

[0030] ​Specifically, the inner support seat serves as the base support structure of the mold, and is made of high-strength material to withstand the pressure during pouring. It is composed of a base, a molding table and a connecting base. The base is firmly fixed to the ground, and the molding table directly participates in the molding process. Its roughly trapezoidal cross-section design ensures the upper width and lower narrowness of the guardrail after molding. The connecting base is located below the base, and the side connecting ears and the edge connecting ears are evenly distributed on it. These connecting ears are made by precise mechanical processing and are used to stably connect with the molding plate group.

[0031] As shown in Figure 1 , Figure 4 and Figure 5 , in this embodiment, a side plate ear 211 corresponding to the side connecting ear 131 is formed at the lower end of the molding side plate 21. A first fixing hole 1311 is opened in the side connecting ear 131, and a second fixing hole 2111 corresponding to the first fixing hole 1311 is provided on the side plate ear 211. A side plate fixing member 2112 is threaded through the first fixing hole 1311 and the second fixing hole 2111 to form a fixed connection.

[0032] As shown in Figure 1 , Figure 4 and Figure 6 , in this embodiment, an edge plate ear 212 corresponding to the edge connecting ear 132 is formed at the lower end of the molding edge plate 22. A third fixing hole 1321 is opened in the edge connecting ear 132, and a fourth fixing hole 2121 corresponding to the third fixing hole 1321 is provided on the edge plate ear 212. An edge plate fixing member 2122 is threaded through the third fixing hole 1321 and the fourth fixing hole 2121 to form a fixed connection.

[0033] In order to realize the stable connection between the molding plate group and the inner support seat, the mold adopts an advanced fixing mechanism. The lower ends of the molding side plate and the molding edge plate are respectively provided with side plate ears and edge plate ears, which accurately correspond to the side connecting ears and the edge connecting ears on the connecting base. By opening first to fourth fixing holes at these connecting parts, and threading high-strength side plate fixing members and edge plate fixing members such as bolts, nuts, etc., the tight fixing between the components of the mold is realized. These fixing members are made of corrosion-resistant materials to ensure the stability of long-term use.

[0034] As shown in Figure 2 , Figure 5 and Figure 6 , in this embodiment, the locking device 23 includes a positioning bolt 231 protruding on the molding side plate 21, a locking arm 232 sleeved on the positioning bolt 231, and a locking protrusion 233 protruding on the molding edge plate 22.

[0035] Wherein, the locking arm 232 is provided with a locking buckle slot 2321 and a capsule-shaped movable hole 2322, the locking buckle slot 2321 receives the locking protrusion, the positioning bolt 231 is arranged in the movable hole 2322, and the locking arm 232 is further provided with an unlocking slope 2323 at one end close to the locking buckle slot 2321.

[0036] In order to ensure the stability of the mold during pouring, the locking device is integrated on the molding side plate. The device is composed of a positioning bolt, a locking arm and a locking protrusion. The positioning bolt is protruding on the molding side plate, and the locking arm is sleeved on the positioning bolt and can rotate freely. The locking arm is provided with a locking buckle slot and a capsule-shaped movable hole. The locking buckle slot is used to receive the locking protrusion on the molding side plate to realize the locking function. The movable hole allows the positioning bolt to be adjusted when needed. In addition, the locking arm is provided with an unlocking slope at one end close to the locking buckle slot, which facilitates easy unlocking of the mold after pouring is completed.

[0037] As shown in Figure 2 , Figure 5 and Figure 6 , in this embodiment, the molding side plate 21 is recessed at both ends, and the molding side plate 22 is provided with an embedded protrusion 221 corresponding to the embedded slot 213.

[0038] As shown in Figure 3 , in this embodiment, the thickness of the molding side plate 21 above is lower than that below.

[0039] As shown in Figure 2 , Figure 5 and Figure 6 , in this embodiment, the base 11 is formed with a protrusion part 111 at one end close to the molding side plate 22, and the molding plate is formed with a recess groove 222 matching the protrusion part 111.

[0040] In order to improve the sealing and stability of the mold, the molding side plate is designed with an embedded slot at both ends, and the molding side plate is provided with an embedded protrusion at one end close to the molding side plate. These protrusions are tightly embedded with the embedded slots, effectively preventing the problem of material leakage during pouring. At the same time, the thickness of the molding side plate above is designed to be lower than that below, which not only meets the strength requirement, but also reduces the overall weight of the mold. In addition, the base is provided with a protrusion part at one end close to the molding side plate, which matches the recess groove on the molding plate, further enhancing the stability of the mold structure.

[0041] In summary, the guardrail production mold ensures the stability and accuracy during pouring through precise design and high-strength material selection, providing a strong guarantee for producing high-quality and standardized guardrail products.
