[0021] ​Clearly, the described embodiments are merely part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-5 A universal mold for prefabricated wall door and window hole, comprising four corner parts 1 and intermediate parts 2 arranged on opposite sides of adjacent two corner parts 1, the corner part 1 is made of high-strength material and has excellent compression resistance and shock resistance. Its design is simple and firm, which can ensure the stability of the prefabricated wall during pouring. At the same time, when pouring the prefabricated wall, the corner part 1 and the intermediate part 2 arranged and adjusted are placed on the top of the specific workbench, which is convenient for the stable pouring operation.

[0023] The side wall of the intermediate part 2 opposite the corner part 1 is provided with a jack 3, and the jack 3 is provided for horizontal movement of the corner part 1 for position adjustment, so as to adjust the overall length of the corner part 1 and the intermediate part 2. The top of the intermediate part 2 is provided with a sliding port 4, and the sliding port 4 and the jack 3 are throughly arranged; the purpose of the arrangement is to facilitate the subsequent fixing of the corner part 1.

[0024] The sliding port 4 is provided with a fixing structure which can be flexibly horizontally moved and used for fixing the corner part 1.

[0025] The fixing structure comprises a pair of sliding grooves 5 arranged in the sliding port 4, the sliding grooves 5 are horizontally slidably connected with sliding blocks 6, the opposite side walls of the two sliding blocks 6 are fixedly connected with the same sliding seat 7, and the sliding seat 7 and the corner part 1 are threadedly connected with the same fastening bolt 8. The staff can realize the adjustment of the position of the fastening bolt 8 by flexibly horizontally moving the sliding seat 7, so that the fastening bolt 8 is still installed on the sliding seat 7 when the position of the corner part 1 and the intermediate part 2 is adjusted, which effectively prevents the fastening bolt 8 from being lost due to random throwing and placing, and affects the subsequent fixing work and use cost.

[0026] A plurality of screw grooves 9 are equidistantly arranged on the top of the corner part 1, and the screw grooves 9 and the fastening bolt 8 are correspondingly arranged. The fastening bolt 8 realizes the fixing of the corner part 1 by cooperating with different screw grooves 9.

[0027] The top of the intermediate part 2 is provided with an annular insertion slot 10, a pair of telescopic rods 11 are fixedly connected in the annular insertion slot 10, the top of the telescopic rod 11 is fixedly connected with a sealing plate 13, the sealing plate 13 is arranged to prevent dust and impurities from entering the intermediate part 2 and hindering the sliding adjustment of the corner part 1 in the jack 3. A spring 12 is sleeved on the telescopic rod 11, and the telescopic rod 11 and the spring 12 are arranged to facilitate the fixing and installation of the sealing plate 13 and the horizontal sliding adjustment of the sliding seat 7 after the sealing plate 13 is vertically taken out upward. And the two ends of the spring 12 are fixedly connected with the annular insertion slot 10 and the sealing plate 13 respectively.

[0028] The sealing plate 13 is vertically slidably connected with the annular slot 10, and the sealing plate 13 and the sliding opening 4 are correspondingly arranged.

[0029] The bottom of the sealing plate 13 is provided with a groove 14 for facilitating the sliding connection with the annular slot 10, and the top of the sealing plate 13 is fixed with a lifting block 15.

[0030] The utility model can be described by the following operation mode to illustrate its functional principle.

[0031] The four corner parts 1 and the middle part 2 are placed on the top of a specific workbench to ensure that they are in the correct position.

[0032] The corner part 1 is horizontally moved through the insertion hole 3 to adjust the overall length of the mold to adapt to the size requirement of the prefabricated wall.

[0033] The through design of the sliding opening 4 and the insertion hole 3 enables the corner part 1 to be flexibly moved in the sliding opening 4.

[0034] When the above operation is performed, the sealing plate 13 is pulled vertically upward in advance to make the sealing plate 13 away from the sliding opening 4, and then there is enough space to operate the sliding seat 7 in the sliding opening 4.

[0035] After all the parts are fixed, the pouring operation of the prefabricated wall can be started.
