It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1 and 2, the mold assembly of the present embodiment can fix a plurality of anchor bolts 10 that are embedded. The mold assembly includes: the steel mold 20, a plurality of tube bodies 30, a plurality of stopper structures 40 and a positioning plate 50. A plurality of anchor bolts 10 pass through the steel mold 20 and are coupled to the steel mold 20. The steel die 20 is provided with a feed inlet 21. The plurality of pipe bodies 30 are fitted over the end portions of the plurality of anchor bolts 10 in a one-to-one correspondence. Each stop structure 40 is disposed on a corresponding tube 30. The stopping structure 40 has a stopping position protruding from the tube 30 and a recovering position retracted into the tube 30. Each tube 30 extends upwardly through the positioning plate 50 and the stop structure is in stop engagement with the positioning plate 50 when in the stop position.

By applying the technical scheme of the embodiment, concrete is poured into the foundation pit through the feeding hole 21. The plurality of pipe bodies 30 are fitted over the end portions of the plurality of anchor bolts 10 in a one-to-one correspondence. The setting of body 30 can prolong the length of rag bolt 10, is convenient for adjust the radial displacement volume that rag bolt 10 produced. The stopper structure 40 of the anchor bolt 10 has a stopper position protruded from the tube body 30 and a withdrawing position retracted into the tube body 30. Each tube 30 extends upwardly through the alignment plate 50. In the pouring process, the concrete is vibrated once every 20cm-40cm is poured. Meanwhile, the positioning plate 50 can move up and down relative to the tube body, and when the positioning plate 50 contacts the stopping structure 40, the positioning plate 50 can apply force to the positioning plate 50, so that the positioning plate 50 extrudes the stopping structure 40 to enable the stopping structure 40 to move from the stopping position to the recovery position. When the stop structure 40 is located at the stop position, if no force is applied to the positioning plate 50, the positioning plate 50 will stop and cooperate with the stop structure 40 to limit the positioning plate 50 to the plurality of tubes 30. At this time, the positioning plate 50 can limit the deflection of the plurality of pipe bodies 30, and thus can effectively reduce the position deviation of the plurality of anchor bolts in the related art. After the foundation is formed, the radial displacement of the exposed part of the foundation bolt 10 is small, and the accuracy of the embedded foundation bolt can be effectively improved. Therefore, the technical scheme of the application effectively solves the problem that the position of the foundation bolt is easy to deviate during construction and pouring in the related art.

For directly processing first accommodation hole on the locating plate, the processing degree of difficulty that can reduce the second accommodation hole is set up to the adapter sleeve, can conveniently process the second accommodation hole on the adapter sleeve. In addition, the second receiving hole is formed to allow the connecting sleeve to have a receiving space, so that the spherical convex pillar can be conveniently clamped in the second receiving hole, so as to limit the positioning plate 50 on the tube body 30.

As shown in fig. 1, in the present embodiment, the stopper structure 40 includes a plurality of stopper structures 40, and the plurality of stopper structures 40 are arranged at intervals along the axial direction of each tube body 30. The stop structures 40 are arranged at intervals along the axial direction of each tube body 30, so that the adjusting speed of the positioning plate 50 can be increased, and the working time can be saved. The end of the foundation bolt 10 is provided with an external thread, and the inner wall of the pipe body 30 is provided with an internal thread matched with the external thread; thus, the pipe body 30 and the anchor bolt 10 are coupled together, and the radial displacement of the anchor bolt 10 can be changed according to the change of the pipe body 30.
