In this embodiment, the four inner mold edge strips 12 are connected to form the square inner mold cavity 14, the inner mold cavity 14 can be used for placing a rigid framework, and in order to prevent the rigid framework from being changed in position during material distribution, and the product quality is not qualified, in this embodiment, the inner mold edge strips 12 (i.e., the upper inner mold edge strip 123 and the lower inner mold edge strip 122) above and below are provided with connecting holes connected with the rigid framework.

In order to align and communicate the outer mold cavity 24 and the inner mold cavity 14, four outer mold bars 22 are used to surround and form a square outer mold cavity 24, the outer mold cavity 24 is used to place a rigid framework, and the rigid framework is prevented from changing position during material distribution, so that the quality of the product is not qualified, and therefore, in the embodiment, the outer mold bars 22 (i.e., the upper outer mold bar 222 and the lower outer mold bar 221) located above and below are provided with connecting holes connected with the rigid framework.

Furthermore, the guiding and adjusting mechanism 3 comprises a guiding rod 32 and a guiding sleeve 31 corresponding to the guiding rod 32, wherein the guiding rod 32 is slidably connected with the guiding sleeve 31; the guide rods 32 are arranged on the inner mold edge strip 12 at intervals along the length direction of the inner mold edge strip 12, the guide sleeves 31 are arranged on the inner mold plate 11, and the inner mold edge strip 12 can move along the length direction of the guide rods 32 under the action of the guide rods 32 and the guide sleeves 31; and/or the guide rods 32 are arranged on the outer mold edge strips 22 at intervals along the length direction of the outer mold edge strips 22, the guide sleeves 31 are arranged on the outer mold plate 21, and the outer mold edge strips 22 can move along the length direction of the guide rods 32 under the action of the guide rods 32 and the guide sleeves 31.

In the above structure, since the first mold assembly 1 and the second mold assembly 2 need to be separated after the production of the prefabricated part is finished, the prefabricated part may be left in the first mold assembly 1 or the second mold assembly 2, and in this embodiment, the prefabricated part may be left in the second mold assembly 2 and moved together with the second mold assembly 2 in a direction away from the first mold assembly 1, the prefabricated part needs to be separated from the inner mold cavity 14 of the first mold assembly 1, and after the prefabricated part is molded, the frictional resistance between the prefabricated part and the inner mold edge strips 12 of the first mold assembly 1 may be large, and thus the inner mold edge strips 12 need to be separated. In the above-described structure, therefore, after the production is completed, the inner mold sides 12 are separated from each other by pulling the guide rods 32 attached to the inner mold sides 12, so that the inner mold cavity 14 is enlarged, the prefabricated parts can be easily separated from the inner mold cavity 14, and the prefabricated parts move together with the second mold assembly 2.
