[0005] The utility model solves the technical problems by adopting the following technical scheme: the guide rod structure for mould convenient to install, including the rod body and the guide bush, the rod body is set in the guide bush, and is connected with the guide bush slidingly, one end of the guide bush is extended to form a clasp ring part, the surface of the guide bush is outwardly convex to form a clamping part, a clamping groove is arranged between the clamping part and the guide bush, one end of the rod body extends outwardly to connect a block, one end of the block is provided with a plurality of positioning rods, the adjacent positioning rods are symmetrically arranged, and a plurality of threads are arranged on the surface of the block.

[0006] Further, one end of the guide bush extends outwardly to form a fixed block, and a fixed groove is arranged at one end of the fixed block.

[0007] Further, one end of the rod body extends outward to form a top rod, and the diameter of the top rod is smaller than the diameter of the rod body.

[0008] Further, the surface of the rod body is smooth, and the guide sleeve is a hollow cylindrical structure, and the inner wall of the guide sleeve is smooth.

[0009] Further, the axial center lines of the rod body and the guide sleeve are on the same horizontal plane.

[0010] Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a convenient-to-install guide rod structure for a mold, a clamping ring part and a clamping part on the guide sleeve form a clamping structure, quick pre-positioning and installation of the guide sleeve are realized through mechanical limiting, through the setting of the connecting block on the rod body and the screw thread on the connecting block, cooperating with the multi-point symmetrical layout of the positioning rod, quick pre-positioning and installation of the rod body can be realized, meanwhile, the positioning rod also effectively prevents the axial movement of the rod body in high-frequency reciprocating motion, and the stability of installation is greatly improved.
