After the fixing sleeve 32 is installed on the surface of the connecting rod 31, the mounting plate 1 and the connecting rod 31 are fixed together by the fixing sleeve 32 and the support plate 33.

[0032] The fixing sleeve 32 is a nut, and both ends of the connecting rod 31 are provided with threads that are compatible with the fixing sleeve 32 for installing the fixing sleeve 32.

[0033] The mold is assembled from multiple assembly plates 1, which facilitates the transportation of the mold and allows it to be assembled into molds of different sizes as needed.

[0034] Both the mounting plate 4 and the assembly plate 1 have multiple mounting holes 9 inside.

[0035] Multiple assembly plates 1 are assembled by installing bolts into the mounting holes 9.

[0036] After the bolts are installed inside the mounting plate 4, the mounting plate 4 is positioned to limit its movement.

[0037] The working principle of the tie-rod type air defense door pre-embedded mold provided by this utility model is as follows:

[0038] In use, multiple assembly plates 1 are assembled together using bolts.

[0039] After inserting the two ends of multiple support rods 2 into the interior of two assembly plates 1 respectively, the multiple assembly plates 1 are connected by fixing multiple fixing sleeves 32 to the surfaces of the multiple support rods 2 respectively.

[0040] After fixing one end of each of the multiple support rods 2 to the inside of the multiple assembly plates 1, the multiple mounting plates 4 can be installed using bolts.
