If the same side template is used for forming the outer wall or the inner wall, the width of the side template is larger than the thickness of the die cavity corresponding to the outer wall, so that the side template can only seal the die cavity and cannot enter the die cavity to adjust the height, the length or the width of the die cavity, and therefore, the side template preferably comprises an outer wall side template and an inner wall side template which are respectively used for the outer wall and the inner wall corresponding to the wall body, and the outer wall side template and the inner wall side template are arranged along the thickness direction of the die cavity; and the output end of the driving mechanism is detachably connected with the corresponding outer wall side template or inner wall side template.

And the detachable ground connection can be realized by connecting through a bolt, connecting through a buckle and other modes, and the detachable ground connection can be realized by connecting and detaching the bolt and the buckle.
Preferably, when the mold cavity is closed in the first step, the driving mechanism matched with the outer wall side template moves the outer wall side template to close the mold cavity; and when the die cavity is closed in the second step, the driving mechanism matched with the inner wall side die plate moves the inner wall side die plate to close the die cavity. When the outer wall is formed, only the outer wall side template needs to be driven to work to seal the die cavity; when the inner wall is formed, the outer wall side template is kept still to continuously seal the die cavity where the outer wall is located, and the inner wall side template moves to seal the die cavity corresponding to the inner wall.
In above-mentioned scheme, because the interior sheathing can remove by the exterior sheathing for there are multiple positional relationship between interior sheathing and the exterior sheathing, in order to inject the initial position of wall body and make things convenient for the shaping, the improvement is, and is a plurality of the side form includes at least three movable side forms and an at least fixed side form that are connected with actuating mechanism, fixed side form is connected on one side of exterior sheathing to close die cavity one side between exterior sheathing and the interior sheathing. In this way, one side of the mould cavity is closed to serve as the starting position for the wall.
In order to shorten the distance that the concrete flows in the mould, avoid the unable corner position of filling to the die cavity of concrete, improve, the slip casting hole is located on the middle section of above-mentioned exterior sheathing or interior sheathing to realize the middle section slip casting.
Finally, the driving mechanism is preferably a hydraulic or pneumatic cylinder, the hydraulic or pneumatic cylinder can drive the side die plate to move, and meanwhile, the side die plate can be stably fixed on a proper position of the die according to needs, so that the side die plate is prevented from being displaced under the action of concrete pumping pressure to influence the forming of a wall body.
Compared with the prior art, the invention has the advantages that: the inner template in the mold can move relative to the outer template to change the thickness of the mold cavity between the inner template and the outer template, and the side templates connected with the driving mechanism can move according to the thickness of the mold cavity to seal the mold cavity, so that when the wall body is molded, the thickness of the mold cavity is adjusted only by moving the inner template to change the thickness of the wall body, and the wall body with different thickness specifications can be molded without repeatedly disassembling the mold and erecting the mold; on the basis that the outer wall is formed in the mold, the inner wall can be formed on the basis of the outer wall by increasing the thickness of the mold cavity, so that the outer wall and the inner wall can be formed in the same pair of molds, the inner wall and the outer wall do not need to be connected subsequently, the process is saved, and the production efficiency is improved; the side templates can seal the die cavity, and simultaneously can control the height, width or/and length of the die cavity according to the requirement, so that walls with different heights, widths or/and lengths can be formed; therefore, the walls with different sizes and specifications can be formed in the same auxiliary die.
