So, when rotating motor 241 starts, drive the pivot of mounting panel 23 and rotate, mounting panel 23 rotates and drives side form 3 rotation to realize the regulation of opposite side form 3 inclination, can make the prefabricated concrete member that the contained angle between side form 3 and the bottom form 1 is different, further improved the suitability of this preparation template.

Referring to fig. 1 and 4, in order to reduce the occurrence of the situation that the side form 3 rotates at will to affect the molding quality of the precast concrete unit when the manufacturing form is used, one end of the movable plate 2 away from the follower plate 24 is provided with a limiting assembly 7 for limiting the rotation of the mounting plate 23 under the influence of self weight in an inclined state to topple.

Referring to fig. 1 and 5, the restriction assembly 7 includes a pawl 71 and a return spring 72, the pawl 71 is rotatably connected to an end of the moving plate 2 away from the follower plate 24, an end of the moving plate 2 away from the follower plate 24 is fixedly connected with the restriction plate 25, and an end of the return spring 72 is fixedly connected with the restriction plate 25, and the other end is fixedly connected with a back of the pawl 71. One end of the rotating shaft of the mounting plate 23 far away from the rotating motor 241 is coaxially fixed with a ratchet wheel 73, a pawl 71 is used for propping against the ratchet wheel 73, a return spring 72 is used for maintaining a state that the pawl 71 is propped against the ratchet wheel 73, and the tooth tip of the ratchet wheel, which is positioned on one side of the mounting plate 23 far away from the pouring space 4, on the ratchet wheel 73 faces away from the pouring space 4.

After the inclination of the side template 3 is adjusted, the pawl 71 is abutted against the ratchet 73 through the arrangement of the pawl 71 and the ratchet 73, the situation that the side template 3 rotates and even topples towards one side far away from the pouring space 4 can be reduced, when the rotating motor 241 drives the mounting plate 23 to rotate towards the pouring space 4, the reset spring 72 is continuously compressed and rebounded, and when the reset spring 72 is in a compressed state, the pawl 71 is separated from the ratchet 73, the mounting plate 23 can rotate towards the pouring space 4, and the inclination adjustment of the side template 3 is realized. When the return spring 72 rebounds, the pawl 71 is meshed with the ratchet on the ratchet wheel 73, so that the possibility that the sideform 3 rotates towards the side far away from the pouring space 4 in the adjustment process of the sideform 3 can be reduced, and the adjustment efficiency of the inclination angle of the sideform 3 can be improved.

In addition, when this preparation template is in the production precast concrete piece, after filling up the concrete in pouring space 4, under the pressure effect of concrete, sideform 3 receives the effort that deviates from pouring space 4, can reduce sideform 3 and take place the possibility that rotates towards pouring space 4 to improve precast concrete piece's shaping quality.

Under the self gravity action of the side template 3, the bottom end of the side template 3 is abutted with the upper surface of the bottom template 1. The thickness of the sideform 3 is small compared to the volume of the concrete prefabricated part, and the bottom end of the sideform 3 has negligible effect on the appearance of the concrete when formed. Thus, when the manufacturing template is transported, the side template 3 can be removed from the mounting plate 23, which is beneficial to reducing the transportation space and facilitating the transportation of the manufacturing template. When the side template 3 is installed, after the second dovetail block 31 is aligned with the second dovetail groove 231, the second dovetail block 31 is inserted into the second dovetail groove 231, and under the self-weight effect of the side template 3, the side template 3 automatically slides down to be abutted with the bottom template 1, so that the installation of the side template 3 is completed.

Thus, after the side form 3 is mounted, the hooks 821 are connected to the retaining rings 232, and the connecting plate 81 is always subjected to a downward pulling force applied to the connecting plate by the tension spring 82 in the process of adjusting the side form 3 by the action of the tension spring 82, so that the connecting plate 81 is abutted on the bottom form 1, and the possibility that the side form 3 and the bottom form 1 are separated in the forming process of the concrete prefabricated part is reduced. When the sideform 3 needs to be removed, the sideform 3 can be removed from the mounting plate 23 by simply removing the hooks 821 from the retaining ring 232.

Referring to fig. 1 and 7, when the thickness of the moving plate 2 is not measured, the length of the sideform 3 is L, the length of the mounting plate 23 is M, the radius of the semicircle at the bottom end of the mounting plate 23 is r, the thickness of the mounting plate 23 is 2r, the angle between the sideform 3 and the bottom form 1 is α, and when the retaining ring 232 is omitted, the length of the tension spring 82 is L.

Assuming that the rotation center point of the mounting plate 23 is a point O, the perpendicular line passing through the long side of the sideform 3 is drawn through the point O, as can be seen from fig. 7:

so that

Also because 1 is more than 0,

so that
